[0002] A punching machine is a device used to punch holes in single-page documents or papers. It is often used in office environments or file storage places. This punch uses the force of a punch to push the perforating blade into the paper, creating holes so that the document can be placed in a folder or snap binder. This type of punch is usually able to process multiple sheets of paper at the same time, which is efficient and is one of the common tools for office document processing.

[0003] However, when the stamping single-page punching mechanism is in use, the paper needs to be placed on the base, and then the punching lifting shaft is compressed downward by the armrest. The punching lifting shaft simultaneously pushes the punching head downward, and the punching head will punch the paper when it contacts the paper. When the punching head approaches the paper, the pressing plate on the lower side of the punching head will press tightly on the paper to prevent the paper from shifting during punching. However, in the process when the pressing plate does not contact the paper, the paper is not fixed on the base, so wind or other factors will easily cause the paper to move on the base. The movement of the paper will cause a position deviation between the punching position and the punching head, resulting in punching errors. Utility Model Content

A spring stopper 8 is provided at the top of the lifting shaft 5, and a lifting reset spring 7 is provided between the spring stopper 8 and the mechanism top box 6. The lifting reset spring 7 is sleeved on the outside of the punching lifting shaft 5, and the punching lifting shaft 5 can drive the fixed plate 12 to move up and down. The outer diameter of the lifting reset spring 7 is smaller than the diameter of the spring stopper 8.

The front sides of the left and right ends of the U-shaped punched handrail 9 are both provided with lifting grooves 11. The two lifting slots 11 are respectively located inside the left and right ends of the mechanism top box 6, and the two lifting slots 11 are both plugged with lifting levers 10. The two lifting levers 10 are fixedly connected to the punching lifting shaft 5 by welding. When the punching single-page punching mechanism is used to punch paper, the punching single-page punching mechanism first needs to be placed on the desktop through the base 1, and then the paper to be punched is placed on the base 1, and the rear end of the paper is blocked by the paper stop bar 2, and then it is necessary to hold the U-shaped punching armrest 9 and press it toward the front and lower side, and the U-shaped punching The hole armrest 9 will contact the two lifting levers 10 during the pressing process, so that the two lifting levers 10 move downward through the lifting slots 11, and the lifting levers 10 will drive the punching lifting shaft 5 to move downward, so that the punching head 4 completes the punching operation on the paper when it moves downward.

The pressing piece 15 is parallel to the base 1. When the punching head 4 is pressed downward by the U-shaped punching armrest 9 to punch the paper, the pressing mechanism 3 will be synchronously driven to move downward. , which will make the pressing piece 15 contact with the paper before the punching head 4. After the pressing piece 15 contacts the paper, as the punching lifting shaft 5 continues to descend, the pressing piece 15 will push the two pressing guide rods 19 upwards, which will compress the pressing springs 16 outside the pressing guide rods 19. After the pressing piece 15 presses the paper, the punching head 4 will descend normally, and the punching head 4 will pass through the perforations 17 inside the pressing piece 15 and contact the paper, and then the paper will be punched. During the punching process, the pressing piece 15 is always pressed tightly on the paper to prevent the paper from being displaced. After the punching is completed, the punching head 4 resets upward, the pressing piece 15 will also reset upward synchronously, and the pressing spring 16 will also reset and push the pressing piece 15 downward, so that the pressing piece 15 is reset to the bottom of the punching head 4, so that the pressing piece 15 can continue to press and fix the next paper.

[0024] like Figure 1 and Figure 3As shown, a paper integral fixing device 14 is arranged at the center of the right end of the base 1, and the paper integral fixing device 14 includes a horizontal bracket 24, a fixing bracket 25, an anti-slip ring 26 and a rotating connecting rod 27. The fixing bracket 25 is fixed to the outer wall of the right end of the base 1, and a rotating connecting rod 27 is inserted into the right end of the fixing bracket 25. The rotating connecting rod 27 can rotate clockwise and counterclockwise on the fixing bracket 25. Two anti-slip rings 26 are sleeved and fixed on the bottom end of the rotating connecting rod 27. The two anti-slip rings 26 are respectively located on the outside of the upper and lower ends of the fixing bracket 25. A horizontal bracket 24 is arranged on the top of the rotating connecting rod 27. The paper integral fixing device 14 also includes a fixed pressure plate 20, a clamping spring 21, a fixed guide rod 22 and an operating head 23. The horizontal bracket A guide hole is provided inside the left end of 24, in which a fixed guide rod 22 is inserted, an operating head 23 is provided at the top of the fixed guide rod 22, a fixed pressure plate 20 is provided at the bottom end of the fixed guide rod 22, a clamping spring 21 is provided between the fixed pressure plate 20 and the horizontal bracket 24, the clamping spring 21 is sleeved on the outside of the fixed guide rod 22, the horizontal bracket 24 is parallel to the base 1, the rotating connecting rod 27 can drive the horizontal bracket 24 to rotate clockwise or counterclockwise above the base 1, the outer wall of the bottom end of the fixed pressure plate 20 can be completely attached to the outer wall of the top end of the base 1, the fixed guide rod 22 can move up and down in the guide hole, the clamping spring 21 can push the fixed pressure plate 20 downward by the spring elastic force, and the diameter of the operating head 23 is larger than the diameter of the guide hole.

[0025] like Figure 1 and Figure 3 As shown, when the paper is placed on the base 1 and is ready to be punched, in the process of pressing down the punching cylinder to punch the paper, although the punching head 4 will fix the paper through the pressing piece 15 when it approaches the paper, the paper is in an unfixed state during the entire process of pressing down the punching head 4. Therefore, in this process, wind force or other factors will easily cause the paper to move on the base 1, which will cause the punching position on the paper to deviate from the punching head 4. Therefore, at this time, the paper overall fixing device 14 is needed to press and fix the entire paper. Specifically, after the paper is placed on the base 1, the user needs to pinch the operating head 23 and pull it upwards, which will pull the fixed pressure plate 20 upwards through the fixed guide rod 22, and then the fixed pressure plate 20 needs to be kept in place. The horizontal bracket 24 is kept in this state and driven to rotate. The horizontal bracket 24 is rotated through the rotating connecting rod 27 on the fixed frame 25, so that the horizontal bracket 24 can be flexibly rotated to the top of the paper. When the fixed pressure plate 20 is rotated to the top of the center of the paper, it stops rotating, and then the operating head 23 pulled upward is released. At this time, the clamping spring 21 will generate a reset elastic force, which will push the fixed pressure plate 20 downward. The fixed pressure plate 20 moves downward through the fixed guide rod 22, so that the fixed pressure plate 20 is firmly pressed on the upper end of the paper, and the paper is clamped and fixed on the base 1. In this way, during the process of punching holes in the paper, the external force will not cause the paper to be displaced, thereby ensuring that the punching head 4 can accurately punch holes in the paper.
