[0032] When pulling up or pressing down the movable rod 302, the movable rod 302 may exceed the predetermined travel range, causing unnecessary impact or damage to the mechanical structure inside the device. Therefore, in an embodiment, the movable rod 302 is provided with a first limiting block 305 and a second limiting block 306. When the action of pulling up the movable rod 302 is performed, the first limiting block 305 will abut against the bottom surface of the top plate of the movable bracket 304, and when it is necessary to press down the movable rod 302, the second limiting block 306 will abut against the top surface of the driving plate 301, limiting the travel range of the movable rod 302, ensuring that the movable rod 302 will not exceed the predetermined travel limit during use, thereby ensuring the safety and reliability of the device.

[0033] After being pulled up, the movable rod 302 may not be stably fixed at the desired position, causing the movable rod 302 to shake or displace during use, affecting the accuracy and stability of the punching. Therefore, in an embodiment, the punching mechanism further comprises a limiting plate 307 and a second spring 308, the movable rod 302 is provided with a limiting slot 309, one end of the limiting plate 307 is hinged to the driving plate 301, the other end of the limiting plate 307 is used for clamping with the limiting slot 309, one end of the second spring 308 is connected with the limiting plate 307, and the other end of the second spring 308 is connected with the driving plate 301, the second spring 308 has a tendency to push the limiting plate 307 into the limiting slot 309. When it is necessary to pull up the movable rod 302, the second spring 308 will perform a resetting action, which will push the limiting plate 307 to tightly combine with the limiting slot 309, thereby ensuring that the movable rod 302 is stably fixed at the desired position, enhancing the stability and reliability of the entire adjusting assembly.

[0034] The limiting plate 307 may be hindered during movement, causing difficulty in clamping. Thus, in an embodiment, the limiting groove 309 is provided with a transition surface 310 near one end of the limiting plate 307, which extends upwardly and inclines toward the limiting plate 307. The transition surface 310 can effectively guide the limiting plate 307, ensuring that the limiting plate 307 can smoothly and accurately reach the predetermined position during movement.

[0035] In the process of paper punching, the paper to be punched is accurately placed into the punching space of the puncher. After aligning the paper, the height of the movable rod 302 is adjusted according to the actual need of the hole position on the paper, the movable rod 302 is pressed at the position where punching is needed, so that the movable rod 302 is in close contact with the end of the cutter body 402; the movable rod 302 is pulled up at the position where punching is not needed, so that the cutter is in a released state, then the handle 201 is rotated to drive the square tube 202 and the gear 203 to rotate, the gear 203 is engaged with the slot 311 on the first sliding block 3, thereby driving the first sliding block 3 to slide along the guide rail. The movable rod 302 moves correspondingly with the movement of the first sliding block 3, when the movable rod 302 presses the cutter body 402, the cutter body 402 passes through the cutter hole on the front blade plate 103 and the rear blade plate 104, and finally forms the required hole position on the paper. After punching is completed, the handle 201 is rotated to reset, and the cutter body 402 is reset synchronously under the elastic force of the first spring 405, so that the equipment can quickly and accurately return to the initial state and be ready for the next punching operation.
