Preferably, the quick-press locker on the rear trailing arm support platform includes a positioning bracket fixed on the rear trailing arm support platform, and a dynamic pressure block hinged with the rear trailing arm support platform. The positioning brace supports the rear trailing arm from below, and the dynamic pressure block presses the rear trailing arm from above.

Preferably, the positioning brace has two horizontal frames arranged in parallel, and the working surface of the dynamic pressure block corresponds to the middle part of the two horizontal frames. The work is stable and the quality of the device is guaranteed.

Preferably, the working surface of the dynamic pressure block is a rack tooth working surface. The rack teeth are consistent with the length direction of the rear trailing arm, which increases the pressing friction.

Preferably, the rear trailing arm support platform is provided with an auxiliary positioning baffle on the rear side of the fixed rear trailing arm of the rear brake. The auxiliary positioning baffle is installed and adjusted according to the angle designed for the mounting bracket of the rear trailing arm.

Preferably, the auxiliary positioning baffle is provided with a vertical plate, and an angle marking line is provided between the auxiliary positioning baffle and the base. When fastening the rear trailing arm mounting bracket, the rear trailing arm mounting bracket can be selected to be fixed at the desired angle.

The beneficial effects of the utility model are: as long as the movable washer in the positioning table is replaced, the rapid switching of rear brake assembly and mixed line production of different specifications can be realized; Selecting the pressing force can protect the workpiece and ensure the safety of other parts on the brake during the assembly process; the positioning is accurate and reliable, and the overall structural strength is strong.
