The frame is provided with a second groove at a position relative to the first groove. The first groove and the second groove form a limiting hole for the screw to rotate and cooperate, and the screw is rotatably connected to the frame through the limiting hole.

[0008] The screw is provided with a limiting block to prevent the screw and the limiting hole from generating relative displacement. The limiting hole is provided with a limiting groove that cooperates with the limiting block. The screw realizes limited relative rotation in the limiting hole through the cooperation between the limiting block and the limiting groove.
