[0025] Specifically, the limiting assembly 27 includes a protrusion 271, a slide groove 272, a fixed seat 273 and a rubber pad 274, wherein protrusions 271 are provided at both ends of the slide plate 23, a slide groove 272 corresponding to the protrusion 271 is provided inside the fixed box 21, a fixed seat 273 is provided at the lower end of the fixed box 21, and a rubber pad 274 is provided at the lower end of the fixed seat 273.

[0026] By adopting the above technical solution, when the skateboard 23 slides, the protrusions 271 at both ends of the skateboard 23 slide in the slide grooves 272 of the fixed box 21. The setting of the protrusions 271 and the slide grooves 272 prevents the skateboard 23 from moving too far and causing pressure damage to the damping rod 25 and the spring 26. When the vibration amplitude is large, the fixed seat 273 at the lower end of the fixed box 21 prevents the bottom plate 22 from hitting the lower end of the fixed box 21, and a rubber pad 274 is set at the lower end of the fixed seat 273 to play a buffering role.

[0027] Specifically, a sliding hole corresponding to the sliding column 24 is provided at the lower end of the fixing box 21 , and an angle of 90 degrees is formed between adjacent sliding columns 24 . The sliding column 24 and the bottom plate 22 as well as the sliding column 24 and the sliding plate 23 are all welded by spot welding.

[0028] By adopting the above technical solution, the sliding column 24 can slide at the lower end of the fixed box 21, and a plurality of sliding columns 24 can be evenly distributed. Spot welding makes the sliding column 24 and the bottom plate 22 as well as the sliding column 24 and the slide plate 23 more secure.

The damping rod 25 and the spring 26 can play a buffering and shock-absorbing role on the caster body 6. By setting the buffer assembly Component 2 can buffer and reduce shock to the caster body 6 to improve the practicality of the device. By setting the limit component 27, the protrusions 271 at both ends of the slide plate 23 slide in the slide groove 272 of the fixed box 21 when the slide plate 23 slides. The setting of the protrusion 271 and the slide groove 272 prevents the slide plate 23 from moving too far and causing pressure damage to the damping rod 25 and the spring 26. When the vibration amplitude is large, the fixed seat 273 at the lower end of the fixed box 21 prevents the bottom plate 22 from hitting the lower end of the fixed box 21, and a rubber pad 274 is set at the lower end of the fixed seat 273 to play a buffering role.
