However, this traditional way of resisting earthquakes will cause damage and aging of the seismic supports after multiple earthquakes, and there is the possibility of fatigue failure or even breakage. The use of traditional seismic supports to resist earthquakes can no longer meet actual needs. Summary of the invention

When an earthquake is transmitted, the second buffer spring can reduce the up-and-down (vertical) vibration, the third buffer spring can reduce the upward vibration, and the lifting ring formed at the end of the buffer connecting rod is fixed to the vertical suspension rod, thereby reducing the vibration generated by the vertical suspension rod.
