A movable groove is formed on the side surface of clamp 29 near the core column, and the other end of the core column is slidably connected to the movable groove. An installation groove 21 is formed on the side surface of the main body 1 away from clamp 18. A worm gear 20 is rotatably connected to the upper surface of the installation groove 21, and a connecting rod is fixedly connected to the lower surface of the worm gear 20. The other end of the connecting rod passes through the installation groove 21 and is fixedly connected to an elliptical block 17. The upper surface of the elliptical block 17 is rotatably connected to the lower surface of the main body 1. Clamp 18 and clamp 29 are L-shaped, and a workpiece 6 is provided on the inner surface of clamp 18 and clamp 29. An installation shaft is rotatably connected to the inner surface of the installation groove 21, and a worm 19 is fixedly connected to the side surface of the installation shaft. The worm 19 and the worm gear 20 mesh. The self-locking characteristics of the worm 19 and worm gear 20 prevent the elliptical block 17 from reversing.

[0024] The upper surface of the mounting bracket 2 has a movable groove 4, and a slider 5 is slidably connected in the movable groove 4. An arc groove plate 16 is fixedly connected to the side surface of the clamp 2 9 near the elliptical block 17. The upper surface of the main body 1 is fixedly connected to the mounting bracket 2.

[0026] Working Principle: During use, the position of clamp 2 9 is first adjusted according to the different widths of workpiece 6. One end of workpiece 6 is placed in the recess on the side surface of clamp 1 8, and then the rotating component 18 is rotated. The rotation of the rotating component 18 will drive the worm gear 19 to rotate on the mounting shaft, and the rotation of the worm gear 19 will drive the worm wheel 20 on the inner surface of the mounting groove 21 to rotate. When the worm wheel 20 rotates, the elliptical block 17 connected to its lower surface by the connecting rod will also rotate. For workpiece 6 with a smaller width, the rotating component 18 can be rotated more times so that the protruding part of the elliptical block 17 abuts against the recessed part of the arc groove plate 16. In this way, clamp 2 9 will move towards clamp 1 8, and at the same time the spring 11 is stretched, and the core column moves in the movable groove. In this way, clamp 2 9 can fix workpieces 6 of different widths within a certain range, which is convenient for punching operations. After fixing, the photoelectric sensor 12 will emit a conspicuous light to mark the place to be punched and transmit the data to the control element. After receiving the data, the control element drives the motor 3 to rotate. The motor 3 drives the threaded rod 13 to rotate, and the rotation of the threaded rod 13 causes the slider 5 to move within the moving groove 4. Subsequently, the electric cylinder 14 drives the punching head 15 to perform punching under the guidance of light, completing the entire punching process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
