Description

TECHNICAL FIELD The present disclosure relates to the technical field of ceiling curtains and in particular to a quickly-mounted ceiling curtain. BACKGROUND The ceiling curtains are sun-shading and daylighting products applied to top surfaces and facades of buildings to directly and efficiently improve sunlight illumination and control photo-thermal radiation to enter indoors through top-surface daylighting parts, thereby achieving indoor thermal environment. The ceiling curtains usually comprise a rectangular frame, which is composed of a top beam, a bottom beam and two side beams. During mounting, most of them are mounted by drilling holes with auxiliary tools and fixing with screws to the mounting positions of the buildings. Drilling holes will not only damage the walls and affect the aesthetics but also produce dusts difficult to clean, leading to time-consuming and labor-consuming mounting and low efficiency. SUMMARY For the above situations in the prior arts, the technical problem to be solved by the present disclosure is to provide a quickly-mounted ceiling curtain, which can be quickly mounted with less time and labor but with higher efficiency. In order to solve the above technical problem, the present disclosure employs the following technical solution: there is provided a quickly-mounted ceiling curtain, which comprises a frame body formed by connecting a top beam, a bottom beam and two side beams. At least one end of the top beam is provided with a holing-free mounting member for supporting the frame body on a mounting position of a building. At least one end of the bottom beam is provided with a holing-free mounting member for supporting the frame body on the mounting position of the building. Preferably, the holing-free mounting member is mounted on one end of the top beam and the other end of the top beam is provided with a corner box; the holing-free mounting member is mounted on one end of the bottom beam and the other end of the bottom beam is provided with a corner box. Preferably, a first connection portion for inserting into the top beam or the bottom beam and a second connection portion for inserting into the side beam are disposed on the corner box. The first connection portion and the second connection portion are perpendicular to each other. Preferably, a detachable cover surface is disposed on the corner box, and a first extension edge and a second extension edge perpendicular to each other are disposed on an outer side of the corner box. A round hole is opened on each of the first extension edge and the second extension edge. Preferably, the holing-free mounting member comprises a connection seat, a moving abutting block, a driving piece, a transmission piece and a locking piece. The connection seat is provided with a first insertion portion for inserting into the top beam or the bottom beam, and a second insertion portion for inserting into the side beam. A cavity is disposed in the connection seat and the moving abutting block is in slide cooperation with the cavity. A linkage shaft is disposed on the moving abutting block and the linkage shaft penetrates through the cavity and is exposed at an outer end of the connection seat and connected with a screw and a washer. The driving piece is mounted inside the cavity and at least one end of the driving piece is in communication with the outside of the connection seat. The transmission piece is sleeved on the linkage shaft and linkage-assembled with the driving piece in a perpendicular crossing way. The locking piece is thread-sleeved on the transmission piece to limit the axial movement of the moving abutting block. Preferably, a first elastic piece is sleeved on the linkage shaft, and both ends of the first elastic piece are respectively abutted against an end of the transmission piece and the moving abutting block. In a natural state, the first elastic piece is in a compressed state so as to push the moving abutting block to move out of the cavity of the connection seat. The washer at the end of the linkage shaft is in blocking connection with an outer wall of the connection seat. Preferably, the driving piece is a worm rod which is disposed at a side away from the moving abutting block inside the cavity. The transmission piece comprises a worm gear portion in cooperation with the worm rod and a screw rod portion in cooperation with the locking piece. A through hole in communication with the cavity is opened on the connection seat for the ends of the worm rod to communicate with the outside. Preferably, the worm gear portion is linked with the screw rod portion through tooth surface meshing. A second elastic piece is sleeved on the linkage shaft, and both ends of the second elastic piece are respectively abutted against the worm gear portion and an inner bottom surface of the cavity. In a natural state, the second elastic piece is in a compressed state to push the worm gear portion to mesh with the screw rod portion. Preferably, a
