The bullet-proof snap ring 223 is an unsealed circular ring, and a plurality of arc-shaped notch grooves 2231 are uniformly arrayed on the bullet-proof snap ring 223. The more arc-shaped notch grooves 2231 are, the easier the bullet-proof snap ring 223 is extruded by the arc-shaped convex ring 227 to deform, the larger resistance can not be formed in the descending process, and the layer-by-layer buffering effect can be formed.

The arcuate collar 227 includes a first ramp 228 and a second ramp 229, the first ramp 228 having a slope that is less than the slope of the second ramp 229, and the first ramp 228 having a slope that is longer than the slope of the second ramp 229.
