After the nuts are loosened, the constraints on the base plate and the fixing frame are released. Then, a person grabs the fixing frame and moves it laterally. When the fixing frame moves, the base plate and the threaded rods move together. When the fixing frame moves to the appropriate position, the nuts are tightened again. The utility model has a lateral position adjustment function and can be adjusted according to the vehicle towed or the environment on site, thereby improving the balance and controllability of the vehicle and having high practicality.

[0018] 2. The utility model is used by taking the traction member out of the vehicle. After the traction member is taken out, the rear ends of the two limit blocks are pinched with one hand and moved inward. When the limit blocks move, they press down on the limit springs through the cooperation of the guide rods and the guide grooves to cause them to contract. When the limit blocks move to the bottom, the front ends are pushed into the fixed frame. Then the personnel push the traction member to make the limit blocks pop out from the limit grooves. This makes it easy to quickly disassemble and assemble the traction member, is simple and convenient to operate, improves the work efficiency of the personnel, and has good flexibility.
