[0011] For further improvement, the limit block is threadedly connected to the rotating rod, and the limit block and the rotating rod are detachable, so that the rotating rod can be detached from the turning handle and can be installed as needed.

[0012] The beneficial effects of the utility model are as follows: when the turning handle is turned, the turning handle drives the rotating shaft to rotate, and the rotating shaft drives the locking block to move toward one end of the guide rail through the screw, and the locking block contacts the guide rail to lock the slider in position. When the mounting block needs to be removed, the screw is turned to make the screw away from the threaded hole, and the sliding block is pulled upward. The sliding block drives the positioning shaft to move upward, so that the positioning shaft is away from the positioning block, and the mounting block can be removed. The structure is simple, and the locking mechanism can be disassembled. BRIEF DESCRIPTION OF THE DRAWINGS
