Specifically, during the working process, the supporting wheel group 400 is installed between the two assembly seats 340. During the movement of the supporting wheel group 400, when the supporting wheel group 400 moves forward, the supporting wheel group 400 moves backward. When the vehicle body is hit, under the action of the two elastic components 300, the two sliders 320 will move up along the two slide grooves 210 respectively, and the impact force of the supporting wheel group 400 will be buffered by two buffer springs 330.
