[0006] Through the above structural setting, the setting of the mounting member can realize the opening and closing of the circular through hole. The hinge between the fixed arc plate and the movable arc plate is similar to a hinge structure. The fixed arc plate and the movable arc plate are hinges, but they are arc-shaped hinges, thus forming a circular through hole. The movable arc plate is movably limited. When it is closed with the fixed arc plate, it is limited by an external object and thus fixed.

[0007] The present application is further provided as follows: Two T-shaped guide rails are arranged on the fixing plate; a limiting block with a U-shaped cross-section is slidably arranged on the fixing plate; a sliding groove adapted to the guide rail is arranged on the limiting block; the limiting block can be horizontally displaced on the surface of the fixing plate along the guide rail under the action of an external force.
