The adjustable composite shock-absorbing rubber pad of claim 6, wherein: when the fixed magnetic ring (323) and the sliding magnetic ring (33) are separated from each other by the maximum distance, the elastic force of the return spring (34) is greater than the repulsive force of the fixed magnetic ring (323) to the sliding magnetic ring (33).
8. The adjustable composite shock-absorbing rubber pad of claim 5, wherein: when the fixed magnetic ring (323) is separated from the sliding magnetic ring (33) by the minimum distance, the elastic force of the return spring (34) is smaller than the repulsive force of the fixed magnetic ring (323) to the sliding magnetic ring (33).
9. The adjustable composite damping rubber pad of claim 1, wherein: the liquid storage bag (35) and the expansion bag (36) are both elastic rubber bag body structures, and the rubber elasticity of the liquid storage bag (35) is smaller than that of the expansion bag (36).
10. The adjustable composite shock-absorbing rubber pad of claim 1, wherein: the side of the expansion bag (36) opposite to the release groove (321) is glued with a wear-resistant layer.
