[0016] To realize the limitation of the turning angle of the tractor:

[0017] Further provided that: the limiting block is fixedly installed on both sides of the rotating plate, and the wear indication line is fixedly installed on both sides of the rotating plate.

[0018] By adopting the above technical scheme, when the tractor turns, the limiting block will rotate synchronously, and when the limiting block rotates to a certain angle, it will be blocked by the limiting block, preventing the semi-trailer and the tractor from forming an excessively large angle, which may cause folding accidents.
