The vertical rod 3 is slidably connected with the bearing block 1, and a compression spring 4 is arranged between the bearing plate 2 and the lower inner wall of the bearing block 1. The vertical rod 3 can improve the stability of the movement of the bearing plate 2, and the compression spring 4 can facilitate the resetting of the bearing plate 2;

[0023] Figure 1 As shown, the limit assembly includes a ring 6 fixedly connected to the bearing block 1, and a cross bar 7 fixedly connected to the clamping plate 5 is slidably connected inside the ring 6. The arrangement of the cross bar 7 can improve the stability of the movement of the clamping plate 5. A tension spring 8 is sleeved on the outer side of the cross bar 7. The two ends of the tension spring 8 are respectively fixedly connected to the clamping plate 5 and the ring 6. The tension spring 8 can facilitate the resetting of the clamping plate 5.
