The cylinder 7 is then started, the cylinder 7 drives the slide bar 8 to move downward, the slide bar 8 drives the cross bar 9 to move downward, so that the circuit breaker contact is pressed and fixed by the cylinder 10 at the end of the cross bar 9, and then the electric telescopic rod 6 is started, the electric telescopic rod 6 drives the placement plate 3 to move downward, so that it can perform drilling operations inside the receiving groove, which can reduce the occurrence of debris splashing. After the drilling is completed, the electric telescopic rod 6 is used to drive the placement plate 3 to move upward, and the cylinder 7 drives the slide bar 8 to move upward, so as to facilitate unloading. The provided slide bar 8 and the movable cross bar 9 make it convenient to clamp and fix the circuit breaker contact, and the fixed position can be easily changed. In addition, the entire placement plate 3 can be stored in the interior of the receiving groove for processing during the processing, which reduces the splashing of debris and reduces safety hazards.

[0027] Furthermore, a sliding hole 13 is provided on the surface of the rotating block 11, and the cross bar 9 is slidably connected to the rotating block 11 through the sliding hole 13. A square groove 14 is provided on the top of the sliding hole 13, and a pressure plate 15 is slidably connected inside the square groove 14. A screw 16 is rotatably connected to the top of the pressure plate 15. The screw 16 threadedly penetrates the rotating block 11 upward, and a turning handle is fixedly installed on the top of the screw 16. Limiting teeth are evenly fixedly installed on the bottom of the pressure plate 15. Limiting tooth grooves are evenly provided on the top of the cross bar 9, and the cross bar 9 can slide in the rotating block 11. When sliding is not required, that is, when the workpiece is to be clamped, the handle can be manually turned to drive the screw 16 to rotate. When the screw 16 rotates, it will move on the turn block 11, so that the screw 16 drives the pressure plate 15 to move synchronously, thereby utilizing the limiting teeth at the bottom of the pressure plate 15 and the limiting tooth grooves at the top of the cross bar 9 to limit and fix, thereby enhancing the stability during the clamping process.

Since the rotation of the rotating block 11 is realized by the cooperation of the worm wheel 18 and the worm 17, and the worm wheel 18 and the worm 17 have a self-locking function, it can provide greater stability when the rotating block 11 does not need to rotate.

[0029] Furthermore, a hair dryer 5 is fixedly installed on the side wall of the workbench 1, and the air outlet of the hair dryer 5 is connected to the air duct 4, and the air duct 4 is installed on the inner wall of the receiving groove. By arranging the hair dryer 5, the placement plate 3 can be moved to the inside of the receiving groove during the drilling process, so that the air outlet of the air duct 4 is flush with the placement plate 3, so that the wind blown out by the hair dryer 5 can use the air duct 4 to act on the upper surface of the placement plate 3, and then act on the workpiece, so that the debris generated during the processing can be directly blown away, and the temperature of the processing parts can be reduced when blowing, thereby protecting the processing parts.

[0030] Furthermore, a placement groove is opened inside the workbench 1, the placement groove and the receiving groove are connected, and a collection box 2 is slidably inserted inside the placement groove so that the air duct 4 blows air on the inner wall of the placement groove and thus blows the processing debris into the collection box 2.

[0031] Furthermore, the slide bar 8 is located at the center of the placement plate 3 so that the cross bar 9 will not exceed the vertical space where the placement plate 3 is located during the sliding process.

[0032] In summary, during use, the circuit breaker contact is placed on the placement plate 3, and then the cross bar 9 is manually held to slide the cross bar 9 in the rotating block 11, and the rotating block 11 itself is rotated, so as to adjust the cylinder 10 at the end of the cross bar 9 to align with the position where the hole needs to be punched on the surface of the circuit breaker contact, and then the cylinder 7 is started, and the cylinder 7 drives the slide bar 8 to move downward, and the slide bar 8 drives the cross bar 9 to move downward, so as to use the cylinder 10 at the end of the cross bar 9 to press and fix the circuit breaker contact, and then the electric telescopic rod 6 is started, and the electric telescopic rod 6 drives the placement plate 3 to move downward, so that it performs a drilling operation inside the receiving groove, which can reduce the occurrence of debris splashing. After the drilling is completed, the electric telescopic rod 6 is used to drive the placement plate 3 to move downward, so as to perform a drilling operation inside the receiving groove, so as to reduce the occurrence of debris splashing. The movable placement plate 3 is moved up, and the cylinder 7 drives the slide bar 8 to move up, so as to facilitate unloading. The slide bar 8 and the movable cross bar 9 are provided, so as to facilitate clamping and fixing of the circuit breaker contacts, and the fixed position can be conveniently changed. In the processing process, the entire placement plate 3 can be stored in the inside of the receiving groove for processing, which reduces the splashing of debris and reduces safety hazards. The cross bar 9 can slide in the rotating block 11. When sliding is not needed, that is, when the workpiece is pressed, the handle can be manually turned, and the handle drives the screw 16 to rotate. When the screw 16 rotates, it will move on the rotating block 11, so that the screw 16 drives the pressure plate 15 to move simultaneously. The cross bar 9 is fixed by the limiting teeth at the bottom of the pressure plate 15 and the limiting teeth at the top of the cross bar 9, thereby enhancing the stability during the clamping process. The cross bar 9 is installed on the rotating block 11, and the rotating block 11 can be rotated to facilitate the adjustment of the position of the cylinder 10 to achieve the clamping of the workpiece. The rotation of the rotating block 11 is driven by the handle to drive the transmission rod 19 to rotate, the transmission rod 19 drives the worm 17 to rotate, the worm 17 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the connecting shaft 20 and the rotating block 11 to rotate synchronously, thereby realizing the activity of the cross bar 9 and stopping after rotating to the appropriate position. Since the rotation of the rotating block 11 is achieved by the cooperation of the worm wheel 18 and the worm 17, The worm wheel 18 and the worm 17 have a self-locking function, so they can provide greater stability when the rotating block 11 does not need to rotate. By setting the hair dryer 5, the placement plate 3 can be moved to the inside of the receiving groove during the drilling process, so that the air outlet of the air duct 4 is flush with the placement plate 3, so that the wind blown out by the hair dryer 5 can use the air duct 4 to act on the upper surface of the placement plate 3, and then act on the workpiece, so that the debris generated during the processing can be directly blown away, and the temperature of the processing parts can be reduced when blowing, so as to protect the processing parts. A collection box 2 is provided in the workbench 1, so that the blown away debris falls directly into the collection box 2 for collection.
