When vibration occurs, the middle hyperbolic ball plate 2 will also be displaced and produce an angular offset, and the internal damping pendulum 8 will generate directional motion potential energy with the hyperbolic ball plate 2 due to inertia, so as to compensate for the potential energy consumed when the spherical slider 3 is displaced and rotated by the damping member 6, so that the device can be stably reset, thereby achieving a more stable reset effect of the device, ensuring continuous support stability, and having the advantages of better use effect, solving the problem in the prior art that the potential energy conversion will generate consumption, resulting in insufficient reset potential energy and inadequate reset, so there is a poor reset effect, which leads to a reduction in the later support effect.
