After the two tightening plates 704 are in place, the hole in the middle of the electric vehicle brake assembly shell is inserted between the surfaces of the two tightening plates 704, and the pressure on the T-shaped pull rod 701 is released again. At this time, the return spring 702 is elastically reset after being stressed, pushing one end of the return spring 702 to move away from the support plate 6, so that the two movable rods 703 symmetrically hinged on the other end of the return spring 702 push the corresponding tightening plates 704 away from each other, thereby braking the electric vehicle brake assembly. The hole in the middle of the shell is tightened and positioned, and the servo motor 502 is started to drive the output end of the servo motor 502 to rotate the gear 503.
