Specifically, the guide rail 31 has a certain inclination angle in the buffer block 3, and the direction of the guide rail 31 inclining towards the buffer block 3 is related to the driving direction of the device arranged at the corner of the road, in the initial state, the joint of the force unloading assembly 4 and the guide rail 31 is pushed to the end position of the guide rail 31 by the second elastic element 5, when the force unloading assembly 4 is impacted by external force, it will move along the guide rail 31 towards the inward-inclining direction of the guide rail 31, at this time, the second elastic member 5 is pressed and compressed, due to the inward inclination of the guide rail 31, the force unloading assembly 4 moves in an oblique line, and has two movement modes, namely moving to one side and moving to the direction in the buffer block 3, at the moment, an external force source, namely, the vehicle is collided, and the deviation guide is carried out on the vehicle after the collision by the traction force and the buffer force deviated to one side, so that the secondary traffic accident caused by the vehicle rushing out of the road is avoided.

Further, the force unloading assembly 4 comprises a force unloading plate 41 and a guide member 42, the guide member 42 is mounted on the force unloading plate 41, one end of the guide member 42 far away from the force unloading plate 41 is slidably connected with the guide rail 31, and the guide member 42 is connected with the second elastic member 5.

Referring to fig. 4, the guide member 42 is specifically a connecting component between the force unloading plate 41 and the buffer block 3, wherein a plurality of balls are disposed on a contact surface of the guide member 42 in sliding connection with the guide rail 31, so that the entire force unloading assembly 4 can normally and smoothly move along the guide rail 31, and the occurrence of jamming, failure of buffering effect, failure of buffering protection for colliding vehicles and deviation of force unloading effect are avoided.
