[0025] In this embodiment, guide plates 9 are fixedly connected at both ends of the horizontal plate 5, and a limit plate 10 is arranged on the outside of the guide plate 9, and an anti-collision cotton 12 is fixedly connected to the outside of the limit plate 10. A first spring 11 is connected between the two limit plates 10 arranged opposite to each other, and the first spring 11 plays a role of buffering and adjustment. A pushing component for pushing the limit plate 10 to move is arranged on the outside of the guide plate 9, and the pushing component includes a side frame 16 fixedly connected to the outside of the guide plate 9, and a rotating shaft 25 rotatably connected to the side frame 16. and a contact plate 15 fixedly connected to the outside of the rotating shaft 25, a mounting seat 17 fixedly connected to the outside of the side frame 16, a shaft 18 rotatably connected to the outside of the mounting seat 17, a pawl 23 fixedly connected to the outside of the shaft 18, a ratchet 24 fixedly connected to the outside of the rotating shaft 25, a shift plate 19 fixedly connected to the outside of the shaft 18, a fixing plate 21 fixedly connected to the outside of the side frame 16, a convex plate 22 fixedly connected to the outside of the fixing plate 21, and a second spring 20 connected between the convex plate 22 and the shift plate 19;
