Specifically, the connecting plate 302 is detachably connected with the mounting plate two 202 through bolts.

[0032] Since the inherent frequency of the steel wire shock absorber is low (which can be as low as 1-5 HZ), the vibration energy can be quickly attenuated, and resonance can be reduced. Therefore, the main shock absorber 1 in the embodiment adopts the multi-strand winding structure of the steel wire shock absorber, and the pre-compression amount is set to 10-30% to reduce the low-frequency response.
