An example apparatus is configured to couple to a trailer and a tow vehicle. The apparatus includes a frame; one or more clamps mounted to the frame and configured to couple the frame to an underplate of the trailer; and a shaft having a first end rotatably coupled to the frame and a second end configured to couple to at least one replicated element of a towed vehicle. The at least one replicated element is configured to engage the tow vehicle.

A ball joint tractor with simple structure and convenient operation is disclosed. When docking is required, it will realize automatic locking, and there is no need for separate personnel to operate. Docking can be completed without getting off the vehicle. The pull ring spring plunger used in the disclosure can be directly inserted into the tractor from the outside of the tractor. When the pull ring spring plunger is damaged, it can be replaced directly without replacing the whole ball joint tractor, which improves the service efficiency of the equipment and avoids the failure of the whole ball joint tractor due to poor spring pin. In the disclosure, by placing the fixing ball in the ball joint groove for locking, the risk of automatic unlocking is avoided, and the safety performance is high and the traction effect is good.
