Description

Technical Field

[0001] This utility model relates to the field of binding equipment technology, specifically a manual punching mechanism. Background Technology

[0002] In office work, organizing documents is essential. The most common method is to punch holes in the corners of the documents and bind them with thread. However, this is cumbersome and inconvenient. As a result, hole punchers have gradually come into use. With continuous social development, the demand for hole punchers is constantly increasing, and various types of hole punchers are available on the market.

[0003] However, existing devices still have certain defects in use. For example, the "Portable Office Punch Machine" disclosed in patent number "CN201620611237.8" uses a clamp to position and hold the paper. However, the clamp can only fix the two ends of the paper. Also, since the thickness of the paper varies each time it is bound, while the height of the clamp is fixed, the design of the clamp is inconvenient for punching holes in paper of different thicknesses. In particular, it can only complete the punching operation, that is, after punching the hole, a nail needs to be installed separately. Utility Model Content

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0026] Please see Figure 1-7 This utility model provides an embodiment of a manual punching mechanism, including a base plate 1. A bracket 2 is provided on one side of the base plate 1. The bracket 2 is slidably connected to a pressure plate 3. A first screw 4 is provided on the side of the bracket 2 to move the pressure plate 3 so that the pressure plate 3 presses the paper between the pressure plate 3 and the base plate 1. A lead screw seat 23 is provided on the upper end face of the bracket 2, and the lead screw seat 23 is threadedly engaged with a second screw 5. The second screw 5 passes through one end of the lead screw seat 23 and is connected to a nail clip 7. The rotation of the second screw 5 within the lead screw seat 23 causes the nail 8 in the nail clip 7 to puncture the paper.

[0027] In summary, because the device uses the first screw 4 to move the pressure plate 3 downwards, it can reliably press the paper around the punched hole while simultaneously pressing paper of different thicknesses by raising and lowering the pressure plate 3. At the same time, the rotation of the second screw 5 causes the nail 8 to pierce the paper. This serves two purposes: first, it punches a hole in the paper; second, after the nail 8 penetrates the paper, the nail tip is pointed upwards and struck with a hammer, causing the nail tip to extend outwards along the radial direction of the nail 8. Therefore, the nail 8 can not only complete the punching operation but also, as needed, directly fix the paper with the nail 8.

[0028] Furthermore, since the pressure plate 3 slides within the groove 14 provided on the bracket 2 via the slider 17, the upward and downward movement trajectory of the pressure plate 3 can be ensured to be stable and reliable.

[0029] To enable the lifting and lowering of the pressure plate 3, an internal threaded seat 11 is provided at the upper end of the slide groove 14. The first screw 4 rotates within the internal threaded seat 11 to achieve the lifting and lowering of the pressure plate 3. Therefore, the screw drive between the first screw 4 and the internal threaded seat 11 ensures that the movement trajectory of the pressure plate 3 will not deviate; secondly, it ensures that the pressure of the pressure plate 3 on the paper is maintained for a long time after pressing; thirdly, the transmission method is simple and convenient, reducing the processing cost of the equipment; and fourthly, the pressure of the pressure plate 3 on the paper can be adjusted at any time by rotating the first screw 4.

[0030] Furthermore, the slider 17 is provided with a connecting seat 9 at one end passing through the slide groove 14; wherein, one end of the first screw 4 passes through the connecting seat 9 and is connected to the provided first retaining ring 15, and the first screw 4 is also provided with a limiting ring 16, and the first screw 4 is rotatably mounted on the connecting seat 9 through the mutual cooperation of the limiting ring 16 and the first retaining ring 15. Based on this, the assembly of the pressure plate 3 and the first screw 4 is simple and convenient.

[0031] In addition, since the bottom end of the slide groove 14 is provided with a notch 13, and the connecting seat 9 passes through the notch 13 and is connected to the first screw 4, the pressure plate 3 can be easily installed on the bracket 2.

[0032] Based on the above solution, since the pressure plate 3 is also provided with an avoidance groove 10 on one side and a groove 12 is also provided in the middle of the base plate 1, the avoidance groove 10 can prevent the pressure plate 3 from interfering with the downward movement of the nail 8. At the same time, the groove 12 allows the nail 8 to continue to move downward a certain distance after piercing the paper, so that one end of the nail 8 can completely penetrate the paper, and the nail tip can be exposed, making it convenient for the user to flatten the nail tip.

[0033] To facilitate the installation of the nail 8, the nail clip 7 includes an installation part 19; wherein, the circumferential surface of the installation part 19 is provided with an inlet 21 for easy insertion of the nail head, and the installation part 19 is connected to the second screw 5 through a connecting pipe 20, while the inlet 21 is connected to a circular hole 22 provided on the bottom surface of the installation part 19.

[0034] In summary, the head of the nail 8 can smoothly enter the nail holder 7 through the insertion port 21, and the nail 8 can rotate after being inserted. Therefore, when the nail 8 encounters resistance during its downward movement, it will not rotate with the second screw 5. This ensures that during the process of the nail 8 piercing the paper, apart from the vertical resistance, other resistances will not be transmitted to the second screw 5.

[0035] Furthermore, since one end of the second screw 5 passes through the connecting tube 20 and connects to the second retaining ring 18 provided inside the connecting tube 20, the nail clip 7 can also rotate freely. This allows the nail 8 to move only in one direction, reducing the transmission of resistance between the nail 8 and the paper to the second screw 5. Therefore, during the process of piercing the paper, the nail 8 can only move up and down and will not rotate with the second screw 5, thus reducing the resistance when the second screw 5 rotates.

[0036] In addition, since both the first screw 4 and the second screw 5 are equipped with handles 6 at their upper ends, it is convenient for the user to move the handles 6 by hand, thereby causing the two screws to rotate, so as to make holes in the paper.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
