Description

TECHNICAL FIELD The present invention relates to the field of sanitary ware technologies, and in particular, to a hinge and a shower door assembly. BACKGROUND In some existing shower door assemblies, a movable door panel is mounted on a fixed door panel by using a hinge, and the movable door panel is opened or closed by rotating around the hinge. An existing hinge generally includes a first body, a second body, and a hinge pin. The first body rotates around the hinge pin relative to the second body. When the first body rotates relative to the second body to an extreme position in which the first body and the second body overlap and approach each other, the first body and the second body abut against each other at ends close to the hinge pin, the first body and the second body have a relatively large gap at ends away from the hinge pin, and there is a specific included angle between the first body and the second body. When the existing hinge is mounted in a shower door assembly, in a rotation process in which the movable door panel overlaps and approaches the fixed door panel, the movable door panel and the fixed door panel more easily abut against each other at the ends close to the hinge pin, because the movable door panel and the fixed door panel each have a specific thickness. Consequently, when the movable door panel rotates relative to the fixed door panel to an extreme position in which the movable door panel and the fixed door panel overlap each other, there is a relatively large included angle between the movable door panel and the fixed door panel. In addition, as the movable door panel has a larger width, a larger gap is caused between the movable door panel and the fixed door panel at the ends away from the hinge pin. JP5563228B2 discloses a door connecting member for connecting a door to an attachment object in an openable and closable manner that includes a first connecting body attached to an attachment surface part of the door, a second connecting body attached to an attachment surface part of the attachment object and disposed to substantially face the first connecting body in a door closed state, and a first connecting arm and a second connecting arm connecting the first connecting body to the second connecting body by rotatably attaching one-end side portions and thereof to the first connecting body, and rotatably attaching the other end portions and thereof to the second connecting body. JPS62169177U discloses a hinge according to the preamble of claim 1. JP2006083558A discloses a double swinging hinge comprising a pair of blocks with front faces swollen in circular arc shape and with back faces of flat shape. TECHNICAL PROBLEM When the first body and the second body are located in the extreme position in which they overlap and approach each other, there is a specific included angle between the first body and the second body. When the movable door panel rotates relative to the fixed door panel and reaches an extreme position in which the movable door panel and the fixed door panel overlap each other, there is a relatively large included angle between the movable door panel and the fixed door panel. A relatively large gap exists between the movable door panel and the fixed door panel at the ends away from the hinge pin, and the movable door panel occupies relatively large space, which in turn limits a user's range of motion. TECHNICAL SOLUTION A hinge according to the invention is defined through the features of claim 1 and includes a first body, a second body, and a hinge part group. The hinge part group includes a first hinge part and a second hinge part, one end of the first hinge part is hinged to the first body on a first axis, the other end of the first hinge part is hinged to the second body on a second axis, one end of the second hinge part is hinged to the first body on a third axis, the other end of the second hinge part is hinged to the second body on a fourth axis, the hinge axes are parallel to each other, and the first hinge part and the second hinge part are distributed along an extension direction of the hinge axes; a distance between the first axis and the second axis is equal to a distance between the third axis and the fourth axis, and a distance between the first axis and the third axis is equal to a distance between the second axis and the fourth axis; and in the case of projection along the extension direction of the hinge axes, in a quadrangle with vertices separately located on the first axis, the second axis, the third axis, and the fourth axis, a vertex located on the first axis and a vertex located on the second axis are two end points of a same diagonal. The first body is hinged to the first hinge part by using a first hinge pin, the first body is hinged to the second hinge part by using a third hinge pin, the second body is hinged to the first hinge part by using a second hinge pin, and the second body is hinged to the second hinge part by using a fourth hinge
