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.

A hitch insert set, hitch system, and method of coupling a hitch cover to a hitch receiver are generally disclosed herein. The hitch system includes a hitch receiver designed to couple to a vehicle, with the hitch receiver defining a receiver opening. The hitch system further includes a hitch cover comprising a tube portion and a cover portion that substantially covers the receiver opening. At least one hitch insert from a hitch insert set couples to the hitch receiver and the tub portion, in use, with the at least one hitch insert filling a gap between the hitch receiver and the tube portion of the hitch cover. The tube portion coupled coupled within the receiver opening such that the tube portion is at least partially retained in place by the at least one hitch insert.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar having a modulus of elasticity, the moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar; and wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle; and wherein the modulus of elasticity of the moment bar is low enough wherein the modulus of elasticity of the moment bar is low enough to reduce displacement of the vehicle when the vehicle and trailer are not parallel is disclosed.

The present invention discloses a trailer connector sleeve lock, comprising a lock cover, a lock tongue piece and a lock hole plate, wherein the lock hole plate is rotatably installed on the lock cover and is provided with a lock hole, and the lock hole plate rotates to the lock cover to serve as the side wall of the lock cover, they are spliced together to form a sleeve lock structure, wherein an opening is arranged above the sleeve lock structure, and the opening is smaller than the size of the lock tongue piece, wherein the lock tongue piece is provided with a lock tongue and is clamped in the sleeve lock structure, wherein the lock tongue extends out of the lock hole and is fixed through an additional lock. The advantageous effects of the present invention are that: the lock cover and the lock hole plate are spliced into a sleeve lock structure, and then the lock tongue piece is clamped in the sleeve lock structure, the lock tongue in the lock tongue piece extends out of the lock hole plate, and then the trailer is locked in such a manner that the lock tongue is fixed by the additional lock, and the installation is convenient. The four sides of the lock tongue piece are completely covered by the lock cover, and the lock tongue is inserted into the lock hole plate, so that a thief cannot damage the sleeve lock by cutting the lock tongue. The damage difficulty is high, the time-consuming is long, and the protection effect is good.

A vehicle hitch insert, assembly, and system are disclosed. As part of the system, a hitch receiver is coupled to a vehicle. A hitch receiver cover is coupled to the hitch receiver and includes a lateral side that defines at least one receiver cover opening with a first diameter. Further, a hitch insert includes a substantially U-shaped main body that is slidably coupled to a lateral side of a hitch receiver cover. The main body includes a first wall defining a plurality of hitch insert openings that partially overlap with one another, with each hitch insert opening having a second diameter, a second wall connected to the first wall at a first joint, and a third wall connected to the second wall at a second joint. In use, a fastener extends through the at least one receiver cover opening and one of the plurality of hitch insert openings.

A trailer hitch lock provides a finned, external shell around a centrally-disposed lock assembly. The material of the shell, its distribution of fins, and the fin dimensions all cooperate to defeat a destructive attack on the lock by a portable angle grinder.
