When the punching head 21 and the punching hole 10 are adjusted to the required diameter, the motor 2 is turned off, and the staff twists the handle 32, and the handle 32 drives the threaded screw 2 30 to rotate. The threaded screw 2 30 drives the bracket 2 27 to move forward through the threaded fixed plate 3 26. When the accessories on the bracket 27 move to the required punching position corresponding to the punching hole 10, stop twisting the handle 32, which is adapted to adjust the punching position of the electrical accessories, and then turn on the cylinder 2 19. The cylinder 2 19 pushes the fixed plate 1 18 to move downward. When the fixed plate 18 moves downward, the slide bar 11 slides downward in the sleeve 5, and the fixed plate 18 drives the disc 2 16 on the rotating shaft 15 to move. The second disc 16 moves downward, and when the bottom of the second disc 16 is attached to the electrical accessories, the second cylinder 19 is closed, and then the first cylinder 17 is opened. The first cylinder 17 pushes the punch head 21 to slide downward on the second disc 16 by compressing the spring 22. When one end of the punch head 21 penetrates the accessory, the punching is completed, which is suitable for punching electrical accessories. After the punching, the waste of the accessory falls into the guide box 24 through the punching hole 10, and then slides from the guide box 24 into the waste barrel 23, which is suitable for centralized collection of the waste after the punching. After the punching is completed, the second cylinder 19 is opened to drive the second disc 16 to rise. When the second disc 16 rises, the punch head 21 is reset on the second disc 16 by the rebound of the spring 22, and then the threaded screw 28 is reversed to remove the punched accessory.
