When the fixed plate 433 receives a force toward the steering wheel 41, the fixed plate 433 approaches the mounting plate 431 and compresses the elastic member 432, and the elastic member 432 contracts in the length direction of the guide bar; when the force is removed, the elastic member 432 extends along the length direction of the guide rod, and the two ends of the elastic member exert force to the mounting plate 431 and the fixing plate 433 outward, so that the fixing plate 433 and the mounting plate 431 are away from each other. Preferably, each elastic member 432 corresponds to one guide rod, and when four elastic members 432 are provided, four guide rods are provided, and the four elastic members 432 are respectively sleeved on the four guide rods one by one.

The head of the bolt 434 and the nut 435 limit the length of the bolt 434 between the fixing plate 433 and the mounting plate 431, that is, limit the maximum distance between the fixing plate 433 and the mounting plate 431, and effectively prevent the bolt 434 from being separated from the mounting plate 431 and the fixing plate 433. Under the above structure, the bolt 434 is not fixed to the fixing plate 433 and the mounting plate 431, so that the bolt 434 can be conveniently detached, adjusted and replaced. Since the distance between the mounting plate 431 and the side wall of the track beam 1 is constant, when the fixing plate 433 is forced to move towards the mounting plate 431, the end of the elastic member 432 on the mounting plate 431 cannot move any more, and the end of the elastic member 432 on the fixing plate 433 is forced to compress.
