A mounting plate 703 is fixedly connected to the bottom of the mounting plate 702. The mounting plate 703 is slidably connected to the upright plate 701 via a slot. An L-shaped groove 704 is formed on one side of the slot, and a circular groove 705 is formed on one side of the L-shaped groove 704. A limiting rod 706 is engaged within the mounting plate 703. The limiting rod 706 is slidably connected within the L-shaped groove 704 and the circular groove 705. A push plate 707 is connected to the bottom of the limiting rod 706. The push plate 707 is slidably connected within the L-shaped groove 704 and pushes... A spring 708 is connected to one side of plate 707, and the other end of spring 708 is connected to the inner wall of L-shaped groove 704. A handle 709 is rotatably connected to the rear part of the inner wall of circular groove 705. A circular plate 710 is connected to the front part of handle 709.
