[0033] A piston body 1, wherein a first mounting hole 11 is provided on the piston body 1;

[0034] A plurality of second mounting holes 12 and a plurality of fluid channels 13 are provided on the piston body 1, and the plurality of second mounting holes 12 and the plurality of fluid channels 13 correspond to each other;

[0035] The blocking member is arranged in the second mounting hole 12 , and at least a part of the blocking member is provided with a damping hole 21 , and the damping hole 21 is communicated with the fluid channel 13 .
