For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.
[0018] In one embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4The bottom of the two moving blocks 13 are fixedly connected to the sliding groove. The front side of the positioning plate 18 is provided with a movable plate 7, and the front side of the movable plate 7 is provided with two guide openings, and the two guide openings are symmetrically arranged on the left and right. The front ends of the two sliding rods 6 pass through adjacent guide openings, and the front side of the positioning plate 18 is fixedly connected to two limit plates 19, and the two limit plates 19 are symmetrically arranged on the left and right. The corresponding sides of the two limit plates 19 are slidably connected to the movable plate 7, and the front side of the movable plate 7 is fixedly connected to two racks 8, and the two racks 8 are symmetrically arranged on the left and right. The front side of the positioning plate 18 is fixedly connected to two connecting plates 17 near the bottom, and the two connecting plates 17 are symmetrically arranged on the left and right. The front side of the connecting plate 17 is plugged with a central shaft, and the front end of the central shaft is fixedly connected to a gear 14, which meshes with the rack 8. The side of the connecting plate 17 away from the movable plate 7 is fixedly connected with a bell 15, and the outside of the central shaft is fixedly sleeved with a touch rod 16.
