The front and rear ends of the movable plate 41 are respectively slidably mounted on the outside of the two limit rods 5. The upper end of the movable plate 41 is rotatably connected with a plurality of push plates 42 at equal intervals. The plurality of push plates 42 are all "L"-shaped structures and the bottoms are all inlaid with counterweight bars 43. The lower left bottom end of the movable plate 41 is fixedly connected with a vertical rod 44, and a through groove 45 is opened inside the vertical rod 44.
