The lateral wall of added resilience gasket and ipsilateral position-limited box is against and added resilience spacer thickness is less than main elastomeric pad；On in this way,
It states structure and has substantially constituted triple protection, i.e., the first bolt head of first layer and position-limited box lateral wall directly abut constraint, the
The head of two layer of second bolt through additional spacer and position-limited box lateral wall it is indirect against, third layer position-limited box inner sidewall through main bullet
Property gasket pushed against indirectly with main nut, and first layer directly hardness against respond it is most fast, the second layer is through additional spacer against response
Speed is placed in the middle, can even respond most slow there are gap between the main elastomeric pad of third layer and main nut and position-limited box inner sidewall；
And first layer is easiest to destroy, the second layer takes second place, the most thick least destructible of the elastomeric pad of third layer, that is to say, that above-mentioned three
