Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of staplers, in particular to a stapler without a needle. Background Art
[0002] The stapler can easily staple several sheets of paper together without staples. The stapler applies pressure to press the paper into uneven patterns, so that the embossed papers are tightly bitten against each other, and the binding is completed, minimizing the damage to the paper, and the stapled papers are easy to remove.
[0003] In the prior art, as the thickness of the paper bound by the stapler increases, the stapling stroke of the stapler will be affected, making it difficult to control the binding force of the stapler. If the force is too small, the bite at the center of the paper will become weaker, making the paper easy to loosen, while if the force is too large, the paper at the edge will be crushed, causing the paper to be damaged. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a stapler without needles, so as to solve the technical problems mentioned in the above background technology.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0011] By adopting the above technical solution, different degrees of pressure can be applied according to the different thicknesses of paper, so as to avoid the paper being crushed while ensuring the bite between the papers and preventing the papers from being loose.
[0012] In a preferred example, the utility model can be further configured as follows: a slide groove is provided on the inner side wall of the buffer groove, an insert block is connected to the slide groove via an elastic member, and a slot for inserting the insert block is provided on the side wall of the pressure block.
[0013] By adopting the above technical solution, the stapler can have a stable pressure threshold during normal binding, so that the stapler can normally bind paper with a smaller thickness.

[0015] By adopting the above technical solution, when the paper thickness is large, the stapler can squeeze the insert block into the slide groove due to excessive stapling pressure, so that the pressing block moves upward in the buffer groove to reduce the stapling pressure.
[0016] In a preferred example, the utility model can be further configured as follows: the top of the second embossed plate and the bottom of the first embossed plate are both provided with evenly distributed convex points, and the convex points between the first embossed plate and the second embossed plate are staggered.
[0017] By adopting the above technical solution, when the first embossing plate and the second embossing plate are pressing the paper together, the staggered convex points can be used to make the patterns on the paper closely bite together, thereby improving the bite strength.
[0018] In a preferred example, the utility model can be further configured as follows: a rubber sleeve is fixedly connected to the top of the pressing plate, and an anti-slip pattern is provided on the top of the rubber sleeve.
[0019] By adopting the above technical solution, the pressure exerted on the hand when pressing the stapler to staple papers can be reduced, thereby improving the user comfort.
[0020] In summary, the present invention includes at least one of the following beneficial technical effects:
[0021] 1. This needleless stapler, by arranging a buffer groove and a pressing block at the bottom of the pressing plate, can separate the insert block from the card slot when the paper thickness is large and the pressure of the first embossed plate pressing the paper exceeds the pressure between the insert block and the card slot, and then the pressing block moves up in the buffer groove to reduce the pressure applied to the paper, which can effectively prevent the edge of the paper from being damaged by excessive pressure, ensure the integrity of the paper and ensure the connection strength after stapling;
[0022] 2. This kind of stapler, by staggeredly arranging the convex points of the first embossed plate and the second embossed plate, allows the indentations left on the paper when the first embossed plate and the second embossed plate are pressed together to bite each other, which can effectively enhance the bite strength between the papers and make the connection of the papers more secure after stapling.

DETAILED DESCRIPTION
[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0029] Example:
[0030] Reference Figure 1 - Figure 3 The utility model discloses a needleless stapler, including a base 1, a pressure plate 2 is hinged on one side of the top of the base 1, a buffer groove 3 is provided on the bottom of the pressure plate 2 away from the hinge, a pressure block 4 is slidably connected in the buffer groove 3, a first embossed plate 5 is fixedly connected to the bottom of the pressure block 4, and a second embossed plate 6 is fixedly connected to the top of the base 1, and the second embossed plate 6 is located directly below the first embossed plate 5.
[0031] In this embodiment, after aligning the paper, it is inserted between the pressing plate 2 and the base 1, and the second embossing plate 6 is located at the position where stapling is required, and then the pressing plate 2 is pressed to clamp the paper with the first embossing plate 5 and the second embossing plate 6, and then pressure is continuously applied to the pressing plate 2 until stapling is completed.
[0032] When the thickness of the stapled paper is relatively large, the first embossing plate 5 will contact the paper in advance and apply pressure to the paper. As the pressure plate 2 continues to apply pressure, the pressure on the paper will continue to increase until the pressure exceeds the resistance between the plug block 12 and the card slot 13. The pressing block 4 presses the plug block 12 into the slide slot 10. After the plug block 12 is separated from the pressing block 4, the pressing block 4 will move up in the buffer slot 3 due to the pressure, thereby effectively preventing the paper from being damaged by excessive pressure.
[0033] See also Figure 2 It can be found that a spring sheet is connected to the hinge between the pressure plate 2 and the base 1, so that the pressure plate 2 can be pushed to reset by the spring sheet after the stapler completes stapling, which can be convenient for continuous use. At the same time, the reset of the pressure plate 2 will also cause the pressure block 4 to reset under the force of gravity and the elastic force of the support spring 9, until the slot 13 contacts the insertion block 12 again, and the insertion block 12 is pushed out by the elastic member 11 to clamp the pressure block 4, preventing the insertion block 12 from falling out of the buffer slot 3.
[0034] The elastic member 11 may be an elastic member with elastic force such as a spring or an airbag, and is used to exert a force on the insert block 12 to extend out of the slide slot 10 to ensure that the insert block 12 can be stably inserted into the slot 13 .
[0035] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a plurality of inwardly concave slots 7 are provided on the top of the pressing block 4 , and plug rods 8 are slidably connected in each of the slots 7 , and the top of the plug rods 8 is fixedly connected to the inner top wall of the buffer groove 3 .
[0036] In this embodiment, because the pressing block 4 needs to slide in the buffer groove 3 to prevent the pressure from continuing to increase when it is subjected to a large pressure, in order to ensure the sliding stability of the pressing block 4, a plurality of plug rods 8 are arranged in the buffer groove 3, and a slot 7 connected to the plug rod 8 is opened on the top of the pressing block 4, so that the pressing block 4 will be restricted by the plug rod 8 when sliding, which can make the sliding of the pressing block 4 more stable and enable the pressing block 4 to always maintain stable contact with the paper when sliding in the buffer groove 3.
[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, a gap is left between the inner bottom wall of the slot 7 and the insertion rod 8 and a support spring 9 is provided, and the bottom of the support spring 9 is fixedly connected to the inner bottom wall of the slot 7 .
[0038] In this embodiment, when the paper thickness is relatively large, the paper in contact with the first embossing plate 5 and the second embossing plate 6 has been embossed with patterns, but the paper located at the center is far away from the first embossing plate 5 and the second embossing plate 6, so the patterns are not obvious, resulting in a poor lamination effect.
[0039] Therefore, a support spring 9 is provided between the slot 7 and the insertion rod 8, so that the support spring 9 is compressed when the pressing block 4 slides in the buffer slot 3, and the support spring 9 applies elastic force to the pressing block 4, thereby slowly increasing the pressure on the paper, changing the pressure increase curve, and improving the stapling effect without damaging the paper.
[0040] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a slide groove 10 is provided on the inner side wall of the buffer groove 3 , an insert block 12 is connected to the slide groove 10 via an elastic member 11 , and a slot 13 for inserting the insert block 12 is provided on the side wall of the pressing block 4 .
[0041] In this embodiment, when the thickness of the stapled paper is within a normal range, because the pressing block 4 slides in the buffer groove 3, a gap is left between the pressing block 4 and the buffer groove 3, which may cause the pressing block 4 to slip out of the buffer groove 3 and be lost. Therefore, a slide groove 10 is opened in the buffer groove 3, and an insert block 12 is connected to the slide groove 10 through an elastic member 11, so that when the pressing block 4 is reset, the slot 13 is inserted and fixed by the insert block 12, which can effectively prevent the pressing block 4 from slipping out of the buffer groove 3.
[0042] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a bevel 14 is processed on the bottom of one side of the insert block 12 close to the pressing block 4 , and a slope 15 that fits the bevel 14 is processed on the inner bottom wall of the slot 13 .
[0043] In this embodiment, when the pressing block 4 is subjected to pressure, the pressing block 4 needs to squeeze the insert block 12 inserted in the slot 13 out of the slot 13 so that the pressing block 4 can slide in the buffer slot 3. Therefore, an angle 14 is provided at the bottom of the insert block 12, and an inclined surface 15 that fits the angle 14 is provided at the bottom of the slot 13, so that when the pressing block 4 applies pressure to the insert block 12, the pressure is converted into a linear force that pushes the insert block 12 to move in the slide groove 10, and when the linear force is greater than the elastic force of the elastic member 11, the insert block 12 is separated from the slot 13.
[0044] In a further preferred embodiment of the present invention, Figure 1 As shown, the top of the second embossed plate 6 and the bottom of the first embossed plate 5 are both provided with evenly distributed convex points, and the convex points between the first embossed plate 5 and the second embossed plate 6 are staggered.
[0045] In the present embodiment, because the paper is squeezed by the second embossing plate 6 and the first embossing plate 5 to form embossing, and then the embossing is closely contacted and bitten, the convex points of the first embossing plate 5 and the second embossing plate 6 are staggered, so that the embossings left by the first embossing plate 5 and the second embossing plate 6 can be bitten with each other, thereby further improving the connection strength of the paper after binding.
[0046] In a further preferred embodiment of the present invention, Figure 1 As shown, a rubber sleeve 16 is fixedly connected to the top of the pressing plate 2, and an anti-slip pattern is provided on the top of the rubber sleeve 16.
[0047] In this embodiment, because the stapler staples the papers together by squeezing, and the squeezing stapler requires the hand to continuously apply pressure to the pressing plate 2, the reaction force on the hand is relatively large, and frequent and continuous use can easily cause hand soreness. Therefore, a rubber sleeve 16 is connected to the top of the pressing plate 2, and the flexibility of the rubber sleeve 16 can reduce the pressure and improve comfort.
[0048] At the same time, the outer wall of the rubber sleeve 16 is provided with anti-skid patterns, which can make it easier to relay when pressed by hand, so as to achieve a better binding effect of the paper.
[0049] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
