Claims (9)

1 . A slide rail assembly, comprising: a first frame; a first bracket comprising a first hollow portion, said first bracket being displaced relative to said first frame; a positioning plate comprising a positioning hole, said positioning plate being set on said first frame and located in said first hollow portion; and a displacement module comprising a first shell, a second shell and a telescopic member, said first shell being combined with said first frame, said second shell being combined with said first bracket, said telescopic member having two opposite ends thereof respectively connected to said first shell and said second shell; thereby, when said telescopic member drives said second shell to be displaced, extended and reset in said first shell, allowing the first bracket to be displaced and extended in a first direction, said positioning plate abuts against one end of said first hollow portion to form a limit to prevent said first bracket from continuing to move in said first direction and drive said first bracket to reset in a second direction opposite to said first direction, and said positioning plate abuts an opposite end of said first hollow portion to form a limit to prevent said first bracket from continuing to move in said second direction.
2 . The slide rail assembly as claimed in claim 1 , wherein said first frame and said positioning plate are integrally formed.
3 . The slide rail assembly as claimed in claim 1 , wherein said first frame and said positioning plate are separately made.
4 . The slide rail assembly as claimed in claim 1 , wherein said first shell comprises a first fixing groove, a second fixing groove, a first accommodating space, a plurality of first limiting portions and a plurality of second limiting portions, said first fixing groove being combined with said first frame, said second limiting portions being respectively abutted against rails of said first frame; said second shell comprises a third fixing groove, a fourth fixing groove and a second accommodating space, said second shell having one end surface thereof abutting said first limiting portions for displacement of said second shell within said first accommodating space, said third fixing groove being combined with said first bracket; said telescopic member has two opposite ends thereof respectively connected to said second fixing groove and said fourth fixing groove, and is accommodated in said first accommodating space and said second accommodating space to extend and reset.
5 . The slide rail assembly as claimed in claim 4 , wherein said first shell further comprises a third limiting portion, said third limiting portion comprising an abutting side surface; said second shell further comprises at least one fourth limiting portion, said at least one fourth limiting portion corresponding to said abutting side surface of said third limiting portion for limiting said second shell in said first accommodating space.
6 . The slide rail assembly as claimed in claim 4 , wherein said first bracket further comprises a bracket protrusion combined with said third fixing groove, said bracket protrusion being set within said second hollow portion for displacement; said first frame further comprises a first protrusion and a second hollow portion, said first protrusion being combined with said first fixing groove.
7 . The slide rail assembly as claimed in claim 1 , wherein said telescopic member is selected from the group of springs, hydraulic rods, pneumatic rods, and other components that are able to be reset after being stretched under force.
8 . The slide rail assembly as claimed in claim 1 , further comprising a second bracket and a rail member respectively installed on said first frame, said second bracket being located at an opposite end of said first bracket relative to said first frame, said rail member comprising an extension section that protrudes after being folded, said extension section being adjacent to said positioning plate to allow one extended end surface of said extension section to be aligned with said positioning hole of said positioning plate.
9 . The slide rail assembly as claimed in claim 1 , wherein said positioning plate further comprises two fixing holes, and said positioning hole is located between said two fixing holes.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail assembly, wherein a first bracket and a displacement module are displaced and assembled on a first frame. 2. Description of the Related Art Generally speaking, the slide rail assembly can be mounted to a column of a rack via a first frame, and a spring is respectively assembled to the first frame and the first bracket, and the first bracket is displaced relative to the first frame, and the spring provides elasticity to the first bracket to make the first bracket displace toward the column. However, as market demands change, how to develop a different type of slide product has become an issue that cannot be ignored. SUMMARY OF THE INVENTION According to the viewpoint of the present invention, a slide rail assembly comprises a first frame; a first bracket being displaced relative to said first frame and comprising a first hollow portion; a positioning plate set on the first frame and located in the first hollow portion and comprising a positioning hole; and a displacement module comprising a first shell combined with the first frame, a second shell combined with the first bracket and a telescopic member having two opposite ends thereof respectively connected to the first shell and the second shell. Thereby, when the telescopic member drives the second shell to be displaced, extended and reset in the first shell, allowing the first bracket to be displaced and extended in a first direction, the positioning plate abuts against one end of the first hollow portion to form a limit to prevent the first bracket from continuing to move in the first direction and drive the first bracket to reset in a second direction opposite to said first direction, and the positioning plate abuts an opposite end of the first hollow portion to form a limit to prevent the first bracket from continuing to move in the second direction. Preferably, the first frame and the positioning plate are integrally formed. Preferably, the first frame and the positioning plate are separately made. Preferably, the first shell comprises a first fixing groove, a second fixing groove, a first accommodating space, a plurality of first limiting portions and a plurality of second limiting portions, the first fixing groove being combined with the first frame, the second limiting portions being respectively abutted against rails of the first frame; the second shell comprises a third fixing groove, a fourth fixing groove and a second accommodating space, the second shell having one end surface thereof abutting the first limiting portions for displacement of the second shell within the first accommodating space, the third fixing groove being combined with the first bracket; the telescopic member has two opposite ends thereof respectively connected to the second fixing groove and the fourth fixing groove, and is accommodated in the first accommodating space and the second accommodating space to extend and reset. Preferably, the first shell further comprises a third limiting portion, the third limiting portion comprising an abutting side surface; the second shell further comprises at least one fourth limiting portion, the at least one fourth limiting portion corresponding to the abutting side surface of the third limiting portion for limiting the second shell in the first accommodating space. Preferably, the first bracket further comprises a bracket protrusion combined with the third fixing groove, the bracket protrusion being set within the second hollow portion for displacement; the first frame further comprises a first protrusion and a second hollow portion, the first protrusion being combined with the first fixing groove. Preferably, the telescopic member is selected from the group of springs, hydraulic rods, pneumatic rods, and other components that are able to be reset after being stretched under force. Preferably, the slide rail assembly further comprises a second bracket and a rail member respectively installed on the first frame, the second bracket being located at an opposite end of the first bracket relative to the first frame, the rail member comprising an extension section that protrudes after being folded, the extension section being adjacent to the positioning plate to allow one extended end surface of the extension section to be aligned with the positioning hole of the positioning plate. Preferably, the positioning plate further comprises two fixing holes, and the positioning hole is located between the two fixing holes.
