After that, the remaining impact force and vibration pass through the shell 4 and contact the limit ring 203. The foam pad 10 bolted to the inside of the limit ring 203 will absorb and disperse the remaining impact force and vibration, and transmit the absorbed and dispersed impact force and vibration to the reinforcement tube 201.
