[0030] Working principle: In actual use, when a ship collides with a bridge pier, the impact plate 24 and the rotating shaft 26 are arranged so that when the impact occurs, the impact plate 24 will shrink inwards due to the impact force, and the side connected to the third spring 231 is used for buffering and unloading through the third spring 231, and the other end shrinks inwards, and at the same time, the first spring 211 and the fourth spring 251 are squeezed, and at the same time, the pull rod 222 is pulled to tilt toward the fixed cylinder 3, and at the same time, the second spring 223 is squeezed to unload the force. When the side of the impact plate 24 close to the rotating shaft 26 is parallel to the rotating shaft 26, the rotating shaft 26 can rotate, that is, it can absorb part of the impact force. When the impact force is less than the spring elastic force, the impact plate 24 and the rotating shaft 26 are restored to their original positions under the joint action of the first spring 211, the second spring 223, the third spring 231, and the fourth spring 251;
