By arranging the second spring 10, when the push block 7 moves horizontally and pushes the support block 18, the second spring 10 will be stretched by the movable plate 17, and when the push block 7 moves back and no longer pushes the support block 18, the second spring 10 will drive the fixing rod 16 to move back by bouncing the movable plate 17, so that the fixing rod 16 can quickly return to the initial position and disengage from the fixing hole 14, thereby ensuring the reuse of the device, and the cost of the second spring 10 is low, and the device is easy to use. In order to increase the scope of use of the device, a fixing rod 16 is fastened to the top of the movable plate 17. Through the cooperation between the top block 15 and the protrusion 5, when the top block 15 moves down and pushes the protrusion 5, the push block 7 will move horizontally and drive the fixing rod 16 to be stuck in the fixing hole 14 by pushing the support block 18.
