The edge of the paper to be punched is placed above the rectangular opening 2. Vertical plates 3 are fixedly connected to the left and right sides of the upper end of the worktable 1. A controller 4 is located on the right end of the right vertical plate 3. The controller 4 can be of model S7-1200, or any existing controller capable of performing this function. The controller 4 is electrically connected to a hydraulic cylinder 6. A [missing information - likely a device name or specification] is fixedly connected to the front upper end of both vertical plates 3. A top plate 5 has a hydraulic cylinder 6 fixedly installed at its upper center. The output end of the hydraulic cylinder 6 passes through the top plate 5 and is fixedly connected to a lifting plate 7. A drilling assembly 8 is provided at the lower end of the lifting plate 7. The drilling assembly 8 includes a mounting block 801, which is located directly above the rectangular opening 2. The upper end of the mounting block 801 is fixedly connected to the lower end of the lifting plate 7. A mounting groove 802 is provided at the left end of the mounting block 801. Limit openings 803 are provided at both the front and rear ends of the mounting groove 802. Several first limit blocks 804 are provided inside the mounting groove 802. A punching rod 805 is fixedly connected to the lower end of a first limiting block 804. Second limiting blocks 806 are fixedly connected to both the front and rear ends of the first limiting block 804. The two second limiting blocks 806 slide within the front and rear limiting openings 803, respectively. The first limiting block 804 and the second limiting blocks 806 are mounted on the mounting block 801 via a fastening assembly 807, which includes bolts and nuts. Furthermore, both the first limiting block 804 and the second limiting block 806 have threaded holes that match the bolts, allowing the bolts to be threaded into the threaded holes. The internal components, along with nuts, secure the first limiting block 804 and the second limiting block 806 to the mounting block 801, thereby securing the drilling rod 805. Both upright plates 3 have inner grooves 17, with a sliding rod 18 fixedly connected inside the groove 17. A slider 19 is slidably connected to the outer surface of the sliding rod 18. The inner sides of the two sliders 19 are fixedly connected to the left and right ends of the lifting plate 7, respectively. The sliders 19 slide up and down on the outer surface of the sliding rod 18, guiding and stabilizing the lifting movement of the lifting plate 7, thus improving the accuracy of the drilling process.

[0030] Reference Figure 2 , Figure 5 and Figure 6As shown, a bidirectional threaded rod 9 is rotatably installed between the two upright plates 3. The bidirectional threaded rod 9 is located behind the top plate 5. A rotating rod 12 is fixedly connected to the right end of the bidirectional threaded rod 9. The right end of the rotating rod 12 extends to the outside of the right upright plate 3 and is fixedly connected to a second turntable 13. The second turntable 13 can drive the rotating rod 12 to rotate inside the upright plate 3, thereby driving the bidirectional threaded rod 9 to rotate. Moving plates 10 are threadedly connected to both ends of the outer surface of the bidirectional threaded rod 9. A first limiting rod 20 is fixedly connected between the two upright plates 3 and the rear of the bidirectional threaded rod 9. The two moving plates 10 are slidably connected.

The upright plate 3 has through holes for the sliding of the second limiting rods 1102. The sliding of the second limiting rods 1102 inside the upright plate 3 can increase the stability of the movement of the L-shaped plate 1101. The inner side of the L-shaped plate 1101 Limiting grooves 1103 are provided at both the front and rear ends. A threaded sleeve 1104 is fixedly connected to the upper end of the L-shaped plate 1101. A one-way threaded rod 1105 is threadedly connected to the inside of the threaded sleeve 1104. A first turntable 1106 is fixedly connected to the upper end of the one-way threaded rod 1105. A fixing plate 1107 is provided on the inner side of the L-shaped plate 1101. Buffer pads are provided at the contact points between the fixing plate 1107 and the L-shaped plate 1101 and the paper. The buffer pads can increase friction to prevent paper slippage and also prevent damage to the paper caused by the fixing plate 1107 and the L-shaped plate 1101, thus improving the adaptability to different types of paper. In accordance with the requirements, the upper end of the fixed plate 1107 is provided with a bearing seat 1108, the upper end of the bearing seat 1108 is rotatably connected to the lower end of the one-way threaded rod 1105, and the front and rear ends of the outer side of the fixed plate 1107 are fixedly connected with limit plates 1109. The limit plates 1109 slide inside the limit groove 1103. A rectangular groove 16 is opened on the front right side of the workbench 1. The rectangular groove 16 is connected to the rectangular opening 2. A collection box 14 is slidably connected inside the rectangular groove 16. A handle 15 is fixedly connected to the right end of the collection box 14. The collection box 14 facilitates the collection of waste generated by drilling and keeps the working environment clean.

[0031] The working principle and usage process of this utility model are as follows: In use, stack the papers to be punched together, aligning their edges. Place the papers on the upper part of the workbench 1, with the punching position positioned above the rectangular opening 2. Then, rotate the second turntable 13. The second turntable 13 drives the bidirectional threaded rod 9 to rotate via the rotating rod 12, thereby causing the movable plate 10 on its outer surface to move inward. During the inward movement of the two movable plates 10, they respectively drive the fixing component 11 at its lower end to move inward until the L-shaped plate 1101 in the fixing component 11 abuts against the left and right ends of the paper, thus limiting the two sides of the paper. Next, rotate the first turntable 1106. The first turntable 1106 drives the unidirectional threaded rod 1105 to rotate inside the threaded sleeve 1104 and above the bearing seat 1108, thereby causing the fixing plate 1107 to move downward. The downward movement of the fixing plate 1107 limits the upper end of the paper, thus completing the punching of the paper. The first limiting block 804 is fixed in place. Then, according to the required number of holes, the corresponding number of first limiting blocks 804 are inserted into the mounting groove 802 from the left end of the mounting block 801. This allows the second limiting blocks 806 connected to the front and rear ends of the first limiting block 804 to slide inside the limiting opening 803. Then, according to the required hole spacing, the distance between two adjacent first limiting blocks 804 and the position and distance between the paper and the punching rods are adjusted using a measuring device. After adjustment, the first limiting blocks 804 and the second limiting blocks 806 are fixed on the mounting block 801 by the fastening assembly 807, thus completing the installation of the punching rods 805. Then, the controller 4 controls the hydraulic cylinder 6 to drive the lifting plate 7 to move downward, thereby driving the punching rods 805 to move downward through the rectangular opening 2. The punching rods 805 can then be used to punch holes in the paper. After punching, the debris falls into the collection box 14 through the rectangular opening 2, thus collecting the debris.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
