[0007] Preferably, the combined bolt includes a third spring washer and a nut.

[0008] In summary:

[0009] In the utility model, the angle of the eccentric wheel can be adjusted according to the tonnage of the heavy object to make the wheel reach the optimal state, thereby preventing the wheel from being subjected to excessive or insufficient force that affects the actual effect; when encountering an uneven road surface, the mechanism of the utility model can ensure the buffering of the auxiliary wheel moving up and down, thereby preventing the auxiliary wheel from slipping and ensuring the stability and driving force of the entire vehicle.
