[0036] Working principle: First, place the processing table 1 to a suitable position, place the plate on the top of the processing table 1, and then start the motor 2. Under the drive of the motor 2, the connecting column 1 3 rotates. When the connecting column 1 3 rotates, the external active roller 12 will rotate accordingly. The active roller 12 drives the driven roller 14 to rotate through the belt 13, and the driven roller 14 drives the connecting column 2 4 to rotate. At this time, the connecting column 1 3 and the connecting column 2 4 will drive the rotating plate 6 to rotate. When the rotating plate 6 rotates, the internal rotating rod 8 will rotate along the inner wall of the rotating groove 7. When the two rotating rods 8 are closest in straight line distance, the two connecting rods 9 move similarly, pushing the base frame 10 to slide on the inner wall of the driven roller 14, thereby clamping and fixing the plate. When the two rotating rods 8 are farthest in straight line distance, the two connecting rods 9 move away from each other, and at this time the clamping plate 11 no longer clamps the plate.

[0037] The front and rear positions of the connecting frame 16 are adjusted by the electric slide rail 15, and the left and right positions of the hydraulic cylinder 18 are adjusted by the electric slide rail 2 17. Then, the hydraulic cylinder 18 is started. As the hydraulic cylinder 18 moves, the edge pressing sleeve 21 contacts the plate. Driven by the hydraulic cylinder 18, the drill bit 19 punches the plate. At this time, the return spring 20 is compressed. The elastic properties of the return spring 20 can make the edge pressing sleeve 21 contact the plate more closely. Then, in conjunction with the positioning hole 22, it can avoid uneven holes during the punching process.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
