The operator starts the electric push rod 15, and the electric push rod 15 starts to drive the pressure plate 13 to move. The pressure plate 13 moves to drive the second connecting plate 12 and the special-shaped plate 11 to rotate. The special-shaped plate 11 rotates around the second support rod 14 to drive the first connecting plate 10 and the fixed plate 8 to rotate, so that the mounting plate 2 is more tightly connected to the plate body 1, which can effectively prevent the bolts from loosening and falling off when the vehicle is driving, causing problems with the car.

[0025] In the utility model, the locking assembly includes a mounting cylinder 6, which is fixed to one side of the plate body 1 by bolts, an L-shaped groove 17 is provided on one side of the mounting cylinder 6, a connecting rod 18 is rotatably connected to the circumferential inner wall of the mounting cylinder 6, a cylindrical pin 16 is welded to one side of the connecting rod 18, and the cylindrical pin 16 slides with the L-shaped groove 17, a spring 19 is welded to the inner wall of the bottom of the mounting cylinder 6, and the spring 19 contacts the connecting rod 18, and a positioning groove is provided on the mounting plate 2. When the rear axle beam and the vehicle need to be aligned, the mounting plate 2 is provided with a positioning groove. When the frame is fixed, the operator first connects the mounting plate 2 with the frame, and then turns the knob 7. The rotation of the knob 7 drives the connecting rod 18 to rotate, and the rotation of the connecting rod 18 drives the cylindrical pin 16 to slide in the L-shaped groove 17. When the cylindrical pin 16 slides to the edge of the L-shaped groove 17, the spring 19 is reset, the cylindrical pin 16 and the connecting rod 18 move, the positioning groove contacts the connecting rod 18, and the connecting rod 18 is pressed against the positioning groove, so that the plate body 1 and the mounting plate 2 are quickly fixed, and the connecting rod 18 is connected.

The knob 7 rotates to drive the connecting rod 18 to rotate, and the connecting rod 18 rotates to drive the cylindrical pin 16 to slide in the L-shaped groove 17. When the cylindrical pin 16 slides to the edge position of the L-shaped groove 17, the spring 19 is reset, the cylindrical pin 16 and the connecting rod 18 move, and the connecting rod 18 is against the positioning groove, thereby quickly fixing the plate body 1 and the mounting plate 2. The operator then starts the electric push rod 15, and the electric push rod 15 starts to drive the pressure plate 13 to move. The pressure plate 13 moves to drive the second connecting plate 12 and the special-shaped plate 11 to rotate. The special-shaped plate 11 rotates around the second support rod 14 to drive the first connecting plate 10 and the fixed plate 8 to rotate. The fixed plate 8 rotates around the first support rod 9 to squeeze the mounting plate 2, so that the mounting plate 2 is more tightly connected to the plate body 1, which can effectively prevent the bolts from loosening and falling off when the vehicle is driving, causing problems with the car.
