The second breach is offered, the angle that the first breach and the second breach are in vertical direction is 90 degree.
Bearing pin projection, the raised size of bearing pin and the first breach and second are provided with the bottom cylindrical of the traction bearing pin
The shape of breach is corresponding.
The spring catch includes spring catch draw ring, spring catch stage casing and spring catch divergent ends, the one end in spring catch stage casing
Spring catch draw ring is provided with, the other end of spring catch draw ring is provided with spring catch divergent ends, and spring catch divergent ends are located at pin shaft hole
Outside.
The traction seat is fixed on vehicle frame trough girder or vehicle frame pipe beam.
The beneficial effects of the utility model are：
1. the utility model employs traction seat and traction bearing pin, and bearing pin projection is provided with traction bearing pin, leading
Draw pin-and-hole and offer the first breach and the second breach respectively, only when bearing pin projection is relative with the first breach and the second breach successively
Ability plug traction bearing pin together, is additionally provided with the spring catch be easy to unlock and extracted.
2. the utility model is compact-sized, occupy little space, traction seat is used cooperatively with traction bearing pin, the moulding of bumper
And the arrangement of license plate will not adversely affect to the arrangement of draw-gear, the plug space of towing pin is larger, and has
There is good auto-lock function, anticreep performance is improved.
