the following points are notable:

1. the second pipe barrel 14 is fixedly provided with a limiting block matched with the second plug rod 16, and the limiting block is arranged to prevent the second plug rod 16 from being separated from the second pipe barrel 14 to cause the failure of left and right shock absorption and buffering, so that the smooth performance of the shock absorption of the part is ensured.

2. The plug plate 13 is made of rubber materials, so that the sealing degree of the pipe barrel one 12 in the plug plate 13 is increased by the elasticity of the rubber, and the primary shock absorption failure caused by the air leakage phenomenon between the pipe barrel one 12 and the plug plate 13 and formed by the pipe barrel one 12, the plug plate 13 and the plug rod one 2 is prevented.

3. The elastic rope 20 can be woven by multiple strands, and the arrangement has the advantage that the elasticity of the elastic rope 20 is increased, so that the three-stage damping effect formed by the second rack 18, the second gear 19, the support rod and the elastic rope 20 is more obvious.
