[0024] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0025] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0026] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0027] Please see Figure 1-5This utility model discloses a one-piece loose-leaf binding punch, comprising a housing 1, a pressure cap 2, and a punch 8. The housing 1 has an accommodating space and a ruler 3 connected thereto. A blade plate 6 and a pass-through component 4 are fixedly connected within the housing 1. A support component is provided in the accommodating space. One end of the pass-through component 4 is connected to the blade plate 6, and the other end is connected to the support component. The blade plate, the pass-through component, and the support component are sequentially connected and integrally formed. In practical use, the one-piece design eliminates the assembly steps of traditional multi-part components, effectively avoiding errors and loosening risks caused by parts assembly. Compared to a split structure, the one-piece design not only significantly shortens the user's installation time but also significantly improves the stability and durability of the overall structure, reduces subsequent maintenance costs, and makes the product more reliable and efficient in use. The paper feed component 4 has a paper inlet 42 and at least two punch holes 41. The punch holes 41 are connected to the paper inlet 42 and pass through the paper feed component 4. One end of the pressure cover 2 is rotatably connected to the blade plate 6. The side of the pressure cover 2 facing the housing 1 has at least two protrusions 21 with different heights. The punch 8 includes a blade cap 81 and a blade body 82. The blade cap 81 abuts against the protrusions 21, and the blade body 82 can pass through the punch holes 41. The blade body 82 is fitted with a spring 97 so that the spring 97 abuts against the paper feed component 4, causing the blade body 82 to return to its original position. When the pressure cover is pressed down, the protrusions abut against the punches in sequence according to their height, and the punches pass through the punch holes. Specifically, the shapes and numbers of the protrusions 21, punches 8, and punch holes 41 are matched. The punch holes 41 can be made into other shapes to cooperate with punches 8 of the same shape, achieving diversity of hole shapes. Specifically, there are five protrusions 21, five punches 8, and five punch holes 41. The end face of the protrusion 21 is arc-shaped, and the radius decreases gradually from the middle to both ends. When the pressure cover 2 is pressed down, the different protrusions 21 squeeze the knife cap 81 and punch holes in the paper one by one. The blade 82 is columnar, and the end face of the blade 82 near the punch hole 41 has a V-shaped recessed area. The V-shaped recessed area reduces the contact area between the blade 82 and the paper. When the user uses the product, the protrusions 21 with different diameters combine with the V-shaped recessed area of ​​the blade 82, which significantly reduces the force required by the user when the device is punching. Compared with the traditional structure, it can save operating force and truly achieve a highly efficient and labor-saving user experience.

[0028] Specifically, one end of the ruler 3 is provided with a locking block 31, and the housing 1 is provided with a locking groove 32. The ruler 3 is engaged with the locking block 31 and the locking groove 32, making the ruler 3 detachably connected to the housing 1. This structural design not only facilitates the installation, disassembly, and replacement of the ruler 3, but also effectively ensures the stability of the ruler 3 during use. At the same time, the ruler 3 on the surface of the housing 1 provides users with intuitive and clear distance reference scales. When drilling holes in multiple stages, users only need to use the ruler 3 as a positioning reference to quickly and accurately determine the position of each hole, thereby ensuring that the height of multiple holes is consistent, effectively avoiding binding deviations caused by misaligned holes, significantly improving the standardization and accuracy of the drilling operation, and greatly optimizing the user experience.

[0029] In this embodiment, the support member 5 is provided with a limiting groove, and the housing 1 is provided with a limiting block. The support member 5 is fixedly connected to the limiting block through the limiting groove. Specifically, the fixed connection between the support member 5 and the limiting block through the limiting groove not only ensures the accurate positioning of the support member 5 during installation and effectively avoids assembly deviations, but also allows for quick separation through simple operations during disassembly, without the need for complex tools or cumbersome steps. This connection method significantly optimizes the product's installation and disassembly process, greatly improves assembly efficiency and maintenance convenience, and balances structural stability with ease of use, providing users with an efficient and worry-free user experience.

[0030] In this embodiment, the accommodating space is provided with a receiving groove 10, which is located below the punch hole 41. The housing 1 is provided with an opening 11 communicating with the receiving groove 10. Specifically, the receiving groove 10 is used to hold the perforated paper scraps to prevent them from scattering, while the opening 11 on the housing 1 provides a convenient channel for cleaning up the paper scraps. Users can easily and quickly pour out the paper scraps in the receiving groove 10 through the opening 11, effectively improving the cleaning efficiency after the punching operation, ensuring a clean and orderly environment for the equipment, and optimizing the overall user experience.

[0031] In this embodiment, the pressure cap 2 is provided with a connecting hole 22, and the blade 6 is provided with a connecting post 23. The pressure cap 2 is rotatably connected to the connecting post 23 through the connecting hole 22. This design allows the pressure cap 2 to rotate flexibly around the connecting post 23, and it can be easily opened and closed during drilling operations. This not only ensures the stability of the structural connection, but also provides users with a smooth operating experience, taking into account both practicality and convenience.

[0032] The working principle of this utility model is as follows:

[0033] When using this product for punching, the user simply needs to place the paper smoothly into the paper inlet 42, then press down on the pressure cover 2. As the pressure cover 2 gradually approaches the housing 1, the protrusion 21 on the pressure cover 2 precisely squeezes the blade cap 81, and the blade 82 passes through the punch hole 41 through the paper to complete the punching operation. The paper scraps generated during the punching process will automatically fall into the receiving groove 10 below the punch hole 41. After the punching operation is completed, the user can easily empty and clean the paper scraps through the opening 11 on the housing 1. When it is necessary to punch the paper in multiple stages, the user only needs to use the scale 3 as a positioning reference to quickly and accurately determine the position of each punch, thereby ensuring that the height of multiple punches is consistent and effectively avoiding binding deviations caused by punching misalignment.

[0034] The advantages of this utility model are:

[0035] 1. This utility model features a blade plate, a pass-through component, and a support component connected in sequence and integrally formed, eliminating the assembly process of traditional multi-part components, effectively avoiding errors and loosening risks caused by parts assembly, and significantly improving the stability and durability of the overall structure.

[0036] 2. The pressure cap is designed with protrusions of varying diameters, which effectively disperses the reaction force generated by the paper when the pressure cap is pressed down, thus saving effort.

[0037] 3. The casing is connected to a ruler. When it is necessary to punch holes in paper in multiple stages, users only need to use the ruler's scale as a positioning reference to quickly and accurately determine the position of each hole, thereby ensuring that the height of multiple holes is consistent and effectively avoiding binding deviations caused by misaligned holes.

[0038] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
