When the bumper body1needs to be repaired, just lift the linkage lever upward, the linkage lever6-3drives the upper locking hook6-1-3to rotate around the hinge shaft of the upper locking hook6-1-3and open the lock cylinder lower groove upwards. At the same time, the limiting lever6-1-8on the upper locking hook6-1-3moves along the locking long hole of the special-shaped through groove on the lower locking hook6-1-4to the opening long hole end of the special-shaped through groove, and pushes the lower locking hook6-1-4to rotate with the lower hinge shaft6-1-10as the center, so that the lower locking hook6-1-4synchronously opens the lock cylinder upper groove downward. When the limiting lever6-1-8moves to the end of the opening long hole at the other end of the special-shaped through groove, the upper locking hook stretches the tension spring at the bottom, and at the same time, the lower locking hook squeezes the torsion spring at the bottom, at this time the lock cylinder upper groove and the lock cylinder lower groove are fully opened. In this way, the bumper body1can be quickly separated from the mounting frame.

Alternatively, when the weight of the bumper body1is too heavy, the lifting devices can be installed on both sides of the mounting frame. Then connect the controller3-2to the vehicle power supply, click the switch of the controller3-2, the controller362drives the telescopic lever of the pushing lever3-1to extend, and makes the telescopic lever hinged with the hinge shaft10on the bumper body1. Then click on the controller3-2to drive the pushing lever3-1back, so that the pushing lever3-1drives the bumper body1to lift up and lean against the mounting frame4, and then the locking bolt6-5passes through the connecting hole2-1on the vertical frame2and the mounting through hole11on the connecting frame6, and then is threaded with the locking nuts6-4to lock the vertical frame2and the connecting frame6. This greatly reduces the labor intensity, and finally the buffer block12is inserted between the bumper body1and the mounting frame4.
