During the process of resetting the bed board 2, the bed board 2 will compress the damping rod 9 to shrink the damping rod 9. When the damping rod 9 is subjected to force, the pressure will be transmitted to the buffer rod 6. With the cooperation of the sleeve 11 and the guide column 12, the buffer rod 6 rotates in the sleeve 11 along the direction of the spiral groove 7 and gradually descends. At this time, the buffer rod 6 rotates between the first connecting block 5 and the second connecting block 8, so that the buffer rod 6 shrinks into the bottom box 3, and the arc-shaped elastic ring 4 is squeezed and deformed by the buffer rod 6. The deformation of the arc-shaped elastic ring 4 and the spiral rotation of the buffer rod 6 in the sleeve 11 are used to buffer the pressure, thereby achieving buffering of the bed board 2.
