Description

Technical Field

[0001] This utility model relates to the field of office equipment technology, specifically to a multi-hole punching machine. Background Technology

[0002] Hole punchers are commonly used devices in office settings, with their core function being to punch holes in paper for subsequent document binding. A typical design features multiple sets of punches spaced apart, capable of punching multiple holes in a single pass to meet basic binding needs. However, traditional hole punchers have significant limitations—the number of punches is fixed and cannot be adjusted, resulting in a complete limitation on the number of holes punched per pass. This makes them unsuitable for different binding standards and difficult to handle ad-hoc special punching scenarios, significantly lacking flexibility and easily leading to operational inconvenience or equipment idleness under diverse office requirements. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-hole punching machine that allows for easy adjustment of the number of holes punched in a single operation, adapting to different punching scenarios, improving applicability, and offering convenient and flexible use.

[0004] This utility model provides a multi-hole punching machine, comprising:

[0005] A base, wherein multiple punched holes are arranged horizontally at intervals on the base;

[0006] A rotating cover, which is located above the base and has one side hinged to the base;

Detailed Implementation

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0028] like Figures 1-4 As shown, this utility model embodiment provides a multi-hole punching machine, including a base 100, a rotating cover 200, and multiple sets of punch assemblies 300.

[0029] The base 100 has multiple punches 110 spaced horizontally.

[0030] The rotating cover 200 is located above the base 100, and one side of it is hinged to the base 100.

[0031] The punch assembly 300 includes a tool holder 310 and a punch 320. The punch 320 is fixed to the tool holder 310 and protrudes from one side of the tool holder 310. One end of the tool holder 310 is hinged to the inside of the rotating cover 200 and can rotate between two positions: the punch 320 facing backward and forward. The tool holder 310 can be temporarily positioned in either the backward or forward position of the punch 320.

[0032] The inner side of the rotating cover 200 is provided with a clearance space 210 to avoid the rearward-facing punches 320. Each punch 320 facing the front can be pressed into the corresponding punch 110 when the rotating cover 200 is pressed down.

[0033] In some embodiments, the clearance space 210 is a groove formed inside the rotating cover 200. It can be understood that the groove here can be a long slot that extends laterally and corresponds to the punches 320 of all punch assemblies 300, or it can include multiple single slots that are distributed laterally and correspond one-to-one with the punches 320 of each punch assembly 300.

[0034] In some embodiments, in order to temporarily position the tool holder 310 in two positions, one with the punch 320 facing backward and the other with the punch 320 facing forward, the inner side of the rotating cover 200 is provided with a first positioning member and a second positioning member for each punch assembly 300. The first positioning member is used to temporarily position the tool holder 310 with the punch 320 facing backward, and the second positioning member is used to temporarily position the tool holder 310 with the punch 320 facing forward.

[0035] Optionally, the first positioning element is a first positioning protrusion 220 protruding from the inner side of the rotating cover 200, and the second positioning element is a second positioning protrusion 230 protruding from the inner side of the rotating cover 200. The tool holder 310 is provided with positioning grooves 311 that can be respectively inserted into the first positioning protrusion 220 or the second positioning protrusion 230. When the positioning groove 311 on the tool holder 310 is stuck outside the first positioning protrusion 220 or the second positioning protrusion 230, it is necessary to overcome the frictional resistance between the positioning groove 311 and the first positioning protrusion 220 or the second positioning protrusion 230 in order to disengage the tool holder 310 from the first positioning protrusion 220 or the second positioning protrusion 230 and achieve temporary positioning of the tool holder 310.

[0036] It is understandable that the first and second positioning elements can temporarily position the tool holder 310 in other ways than this, such as magnetic attraction.

[0037] In some embodiments, paper positioning members 120 are respectively provided at both ends of the base 100 near a row of punch holes 110. A gap 121 for paper to be inserted is formed between the front part of the paper positioning member 120 and the base 100. When the paper is punched, the side of the punched paper can be inserted into the gap 121 between the paper positioning member 120 and the base 100, which makes it easier to control the edge distance of the punched paper.

[0038] In some embodiments, the rotating cover 200 has first latching portions 240 on both sides, and the base 100 has first latching positions 130 on both sides that can engage with each of the first latching portions 240 when the rotating cover 200 and the base 100 are closed. When stored, the rotating cover 200 can be closed, and the rotating cover 200 and the base 100 are fastened together by the first latching portions 240 and the first latching positions 130, which can prevent the rotating cover 200 from being accidentally opened.

[0039] In some embodiments, a positioning ruler 400 is provided on one side of the base 100. The positioning ruler 400 is provided with two adjusting grooves 410 extending in the front-rear direction. A positioning post 420 protruding from the upper side of the positioning ruler 400 is slidably installed in each adjusting groove 410. When the positioning post 420 slides to the front end of the adjusting groove 410, it is on the same straight line as each punch 110.

[0040] By setting positioning posts 420, during continuous punching, the positioning posts 420 can be positioned within the previously punched holes on the paper to determine the spacing between the two sets of holes. With two positioning posts 420, during continuous punching, the unused positioning posts 420 slide backward, while the required positioning posts 420 slide forward until they are aligned with each punch 110. This allows selection of the required positioning posts 420 for continuous punching. By using different positioning posts 420 to position different holes on the paper, the punching spacing between adjacent sets of holes can be adjusted.

[0041] In some embodiments, one end of the positioning ruler 400 is hinged to one end of the base 100 and can rotate between an unfolded state and a folded state. When the positioning ruler 400 is rotated to the unfolded state, it is substantially flush with the top surface of the base 100. When the positioning ruler 400 is rotated to the folded state, it is located on the underside of the base 100. The positioning ruler 400 can be unfolded in use and folded up in storage, which can reduce the storage volume.

[0042] Preferably, the positioning ruler 400 has a second latching part 430 at its end, and the base 100 has a second latching position 140 that can engage with the second latching part 430 when the positioning ruler 400 is folded under the base 100. When the positioning ruler 400 is folded up, it can engage with the second latching position 140 through the second latching part 430 to prevent the positioning ruler 400 from being accidentally opened. When the positioning ruler 400 is unfolded, it can be supported by the second latching part 430.

[0043] In some embodiments, the bottom of the base 100 is provided with a paper scrap box 500 that can be opened or closed. When closed, the paper scrap box 500 is located below each punch 110. When punching, the paper scrap box 500 is closed, and the scrap generated during punching is collected in the paper scrap box 500. When it is necessary to clean the paper scraps in the paper scrap box 500, the paper scrap box 500 can be opened.

[0044] In this embodiment, the punch assembly 300 to be used is rotated to the position where the punch 320 faces forward, and the punch assembly 300 not to be used is rotated to the position where it faces backward. When the cover 200 is rotated, the punch 320 facing forward can be pressed into the corresponding punch hole 110, thereby punching holes in the paper placed on the base 100. The punch 320 facing backward cannot punch holes in the paper on the base 100. This design makes it easy to adjust the number of holes punched at one time to adapt to different punching scenarios, improve applicability, and make it convenient and flexible to use.

[0045] In this embodiment, the punch assembly 300 is specifically configured with 6 punches, which can meet the punching requirements of 5 holes, 6 holes and 3 holes in a single punching operation, and can meet the binding requirements of 30 holes, 24 holes, 20 holes, 6 holes and 9 holes in continuous punching operation. According to the paper size, it can meet the punching and binding requirements of A4, A5, B5, A6 and A7, etc., so it is not limited by paper size, flexible and versatile, multi-purpose, and does not limit the number of holes.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
