[0034] Specifically, the buffer plate 22 is arranged on the support rod 19, the buffer plate 22 directly contacts the bottom of the container, when the container is hoisted or transported, the buffer plate 22 is first impacted and moves downward, the damping rod 23 and the spring 24 are arranged at the bottom of the buffer plate 22 and the inner bottom of the support rod 19. When the buffer plate 22 moves downward, the damping rod 23 moves with the buffer plate 22, the damping medium in the damping rod 23 generates damping force through the damping hole or the valve, hinders the rapid movement of the buffer plate 22, and the spring 24 is compressed to absorb the impact force by using the elastic potential energy.
