Even if the internal structure is creatively improved, there is an upper limit to its shock absorption effect. Therefore, there is room for improvement in actual use. Summary of the invention

During use, the ring at the top position drives the connecting column to move downward synchronously and squeezes the elastic member, so as to achieve the purpose of rebound shock absorption through the elastic member.

[0008] Preferably, the detection module is a distance sensor installed on the inner sides of the two support columns, one distance sensor is the transmitting end and the other distance sensor is the receiving end. When the two support columns are close to each other, it indicates that the entire shock absorbing assembly is in a buffering state. At this time, the buffering value can be calculated by the change in the distance between the two.
