Description

Technical Field

[0001] This utility model relates to the field of stapler technology, and in particular to a right-angle stapler and its staples. Background Technology

[0002] Staplers are a common stationery item in people's daily lives and offices. They mainly use staples to bind paper, cards or other thin materials together.

[0003] For example, a handheld stapler disclosed in an existing patent (publication number: CN210678583U) has the following characteristics: When the staple path assembly encounters the pin groove of the base assembly and cannot go down, the upper cover assembly continues to increase the force, and the blade in the upper cover assembly pushes the staples in the staple path assembly out of the staple outlet, thus forming the staple-driving operation; the handle and the hinge plate both form a first lever with the left end of the base assembly, and the upper cover assembly and the staple path assembly both form a second lever with the right end of the base assembly. The hinge plate connects the first lever and the second lever, and the hinge plate receives the force of the first lever as the driving force of the second lever, resulting in a good labor-saving effect.

[0004] However, the aforementioned handheld stapler cannot produce staples at right angles when in use.

[0005] Therefore, there is an urgent need to develop a staple that can produce right angles. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a right-angle stapler and its staples, aiming to solve the technical problem that the existing staplers cannot staple at right angles.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A right-angle stapler includes a top cover, a base, a staple storage compartment, and a handle. One end of the top cover is hinged to a first end of the base, and a staple pusher is provided at the other end of the top cover. A pressure device is provided at the second end of the base corresponding to the staple pusher. The opposite side walls of the handle are respectively hinged to the inner side walls of the base. Both ends of the handle extend beyond the base. One end of the handle is a grip, and the other end consists of two interconnected fasteners. The opposite side walls of the top cover have concave arc-shaped grooves facing the base. A pin is provided between the two arc-shaped grooves, and the two ends of the pin located outside the arc-shaped grooves are detachably connected to the two fasteners. The handle can drive the pin to slide along the arc-shaped grooves. A first reset member is provided between the pin and the top cover for the sliding reset of the pin. One end of the staple cartridge is hinged to the top cover. The axis of rotation of the staple cartridge around the top cover is parallel to the axis of rotation of the top cover around the base. The staple cartridge is located between the base and the top cover. A pusher is slidably disposed inside the staple cartridge. A second reset member is connected between the pusher and the staple cartridge for sliding reset of the pusher. An upper presser is disposed at the other end of the staple cartridge corresponding to the position of the lower presser. The upper presser has a staple ejection groove for ejecting staples. The staple pusher is used to push the staples in the staple cartridge from the position of the staple ejection groove into the space between the upper presser and the lower presser. The staple ejection groove is an inverted V-shaped groove with a 90° angle. The surface of the upper presser facing the lower presser is a first inverted V-shaped surface with a 90° angle. The surface of the lower presser facing the upper presser is a second inverted V-shaped surface with a 90° angle.

[0009] Furthermore, the surface on the pusher used for pushing the nail is a third inverted V-shaped surface with a 90° angle.

[0010] Furthermore, the right-angle stapler also includes a limiter, which is adjustablely disposed at the second end of the base. The extension direction of the limiter is the same as the extension direction of the base, and the limiter can be adjusted along the extension direction of the base.

[0011] Furthermore, the limiter includes a U-shaped seat, the inner sidewall of the first end of the U-shaped seat abuts against the outer sidewall of the base, the second end of the U-shaped seat extends beyond the base, and adjustment parts are respectively provided on the two side walls of the U-shaped seat. The adjustment parts are used to adjust the movement of the U-shaped seat along the extension direction of the base, and the two outer side walls of the first end of the U-shaped seat are fixed with vertically extending limit parts.

[0012] Furthermore, each of the adjustment parts includes a plurality of adjustment holes, and the plurality of adjustment holes of each adjustment part are arranged along the extension direction of the U-shaped seat, and the adjustment holes are locked to the U-shape by a locking member.

[0013] Furthermore, the multiple adjustment holes of each of the adjustment parts are interconnected.

[0014] Furthermore, each of the adjustment parts includes a U-shaped groove, the U-shaped groove being along the extending direction of the U-shaped seat, and the U-shaped groove and the U-shape being locked together by a locking member.

[0015] This utility model also provides a staple, which is clamped between the pusher and the presser. The staple includes a main body and two legs. The main body includes a first inclined part and a second inclined part. One end of the first inclined part and one end of the second inclined part are connected to form an inverted V-shaped structure at 90°. One leg is vertically fixed to the other end of the first inclined part, and the other leg is vertically fixed to the other end of the second inclined part.

[0016] Furthermore, the main body also includes a connecting portion, through which the first inclined portion and the second inclined portion are connected.

[0017] Furthermore, the support leg is integrally formed with the main body.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] When using this right-angle stapler, the first step is to place two adjacent sheets of paper from the cardboard box lid between the upper and lower pressure units, ensuring that the right angle formed by the two adjacent sheets corresponds to the right angle on the lower surface of the upper pressure unit and the right angle on the upper surface of the lower pressure unit. Then, the handle is gripped and brought close to the lid. The handle then drives the pin to slide from the end of the arc-shaped groove away from the upper pressure unit to the end of the arc-shaped groove near the upper pressure unit. This causes the staple pusher on the lid to push the staples stored in the staple magazine out of the staple slot of the upper pressure unit, thus staples the two adjacent sheets of paper together. This results in right-angle staples, achieving a 90° binding effect. This method is suitable for binding the folded parts of cardboard boxes and is convenient for small businesses that need cardboard box packaging to make their own small-scale cardboard boxes.

[0037] Please refer to Figure 1 - Figure 9 In one aspect, this utility model provides a right-angle stapler, including an upper cover 1, a base 2, a staple storage compartment 3, an upper pressure unit 4, a lower pressure unit 5, a pusher 6, a limiter 7, and a handle 8. One end of the upper cover 1 is hinged to the first end of the base 2, and the other end of the upper cover 1 is fixed with a staple pusher 12; the lower pressure unit 5 is fixed to the second end of the base 2 corresponding to the position of the staple pusher 12. Furthermore, the upper cover 1 has concave arc-shaped grooves 10 on its opposite side walls, which are recessed towards the base 2. A pin 11 is disposed between the two arc-shaped grooves 10, with both ends of the pin 11 respectively placed within the two arc-shaped grooves 10. The axial direction of the pin 11 is perpendicular to the horizontal direction of the extension of the upper cover 1 or the base 2. A first reset element (not shown) is provided between the pin 11 and the upper cover 1. The extension direction of the first reset element is the same as the extension direction of the upper cover 1. The first reset element is a spring, used for the sliding reset of the pin 11.

[0038] One end of the staple storage compartment 3 is hinged to the upper cover 1, and the other end of the staple storage compartment 3 is provided with an upper pressure device 4 corresponding to the position of the lower pressure device 5. The staple storage compartment 3 is located between the base 2 and the upper cover 1. The axis of rotation of the staple storage compartment 3 around the upper cover 1 is parallel to the axis of rotation of the upper cover 1 around the base 2. A pusher 6 is slidably disposed inside the staple storage compartment 3 along its own axial direction. A second reset member 61 is connected between the pusher 6 and the staple storage compartment 3. The second reset member 61 is a spring and is used for the sliding reset of the pusher 6. In addition, the upper pressure device 4 has a staple dispensing groove 40 for dispensing staples; such as Figure 6 As shown, the surface of the upper pressure unit 4 facing the lower pressure unit 5 is a first inverted V-shaped surface 41 with a 90° angle, and the staple outlet groove 40 extends from top to bottom through the first inverted V-shaped surface 41; the surface of the lower pressure unit 5 facing the upper pressure unit 4 is a second inverted V-shaped surface 50 with a 90° angle; and the staple pusher 12 is mainly used to push the staples in the staple storage compartment 3 from the position of the staple outlet groove 40 into the space between the upper pressure unit 4 and the lower pressure unit 5; the staple pushing surface 120 of the staple pusher 12 is set as an inverted V-shaped surface with a 90° angle to accommodate the staples of this embodiment.

[0039] The opposite side walls of the handle 8 are hinged to the side walls of the base 2. Both ends of the handle 8 extend beyond the base 2. One end of the handle 8 is a grip 81, and the other end is two interconnected fasteners 80. The fasteners 80 are integrally connected to the grip 81. The two fasteners 80 are detachably connected to the two ends of the pin 11 located outside the arc groove 10. The two fasteners 80 are located on the outer side of the upper cover 1 and the nail storage compartment 3, respectively, and the handle 8 can drive the pin 11 to slide along the arc groove 10. Specifically, each fastener 80 has a slot 801 adapted to the pin 11, and the slot 801 hooks onto the pin 11. Before use, the right-angle stapler of this embodiment has the pin 11 located at the end away from the staple pusher 12 in the arc groove 10 (the rear end), and the slots 801 on the two fasteners 80 respectively engage with the two ends of the pin 11 extending outward from the outer side of the upper cover 1. When stapled, the right-angle stapler of this embodiment first places two adjacent sheets of paper from the paper box cover 13 between the upper pressure device 4 and the lower pressure device 5, and makes the right angle formed by the two adjacent sheets of paper in the paper box correspond to the right angle on the lower surface of the upper pressure device 4 and the right angle on the upper surface of the lower pressure device 5. Then, hold the gripping part 81 of the handle 8 so that the handle 8 The grip 81 is brought close to the top cover 1 (i.e., the handle 8 is turned counterclockwise). At this time, the handle 8 will drive the pin 11 to slide from the end away from the upper pressure unit 4 (rear end) in the arc groove 10 to the end close to the upper pressure unit 4 (front end) in the arc groove 10. This will drive the staple pusher 12 on the top cover 1 to push the staples 9 stored in the staple storage compartment 3 out of the staple outlet slot 40 of the upper pressure unit 4. This will cause the staples 9 to bind two adjacent papers of the paper box together, thereby making the stapler produce right-angle staples 9, achieving a 90° binding effect (e.g., ...). Figure 10 As shown), the right-angle stapler of this embodiment can be used for 130-position staplering of the folded part of a cardboard box, making it convenient for stores that need cardboard box packaging to make small-scale cardboard boxes themselves.

[0040] Before binding, the right-angle stapler of this embodiment places a row of staples 9 into the staple storage compartment 3. The specific operation is as follows: Rotate the gripping part 81 of the handle 8 clockwise to disengage the slot 801 on the fastener 80 from the pin 11. Then rotate the top cover 1 clockwise to lift it, thus placing the staples 9 into the staple storage compartment 3. The row of staples 9 is held between the pusher 6 and the pressure unit 4. It should be noted that after placing the staples 9 and ensuring they are in place, rotate the top cover 1 counterclockwise to lower it and engage the slot 801 on the fastener 80 with the pin 11. At this time, the end of the pin 11 is located within the arc-shaped groove 10, away from the end of the pressure unit 4.

[0041] In this embodiment, the limiter 7 is adjustablely disposed at the second end of the base 2. The extension direction of the limiter 7 is the same as the extension direction of the base 2, and the limiter 7 can be adjusted along the extension direction of the base 2. The limiter 7 is mainly used to ensure that the staples fall in the same position every time they are bound, which can greatly improve the accuracy and consistency of binding, making the bound paper boxes more aesthetically pleasing.

[0042] Specifically, the limiter 7 includes a U-shaped seat 70, the inner sidewall of the first end of the U-shaped seat 70 abuts against the outer sidewall of the base 2, the second end of the U-shaped seat 70 extends beyond the base 2, and adjustment parts are respectively provided on the two side walls of the U-shaped seat 70, which are used to adjust the movement of the U-shaped seat 70 along the extension direction of the base 2; in addition, the two outer side walls of the first end of the U-shaped seat 70 are fixed with a limiting part 702 extending vertically. When binding the lid of the paper box, the adjacent folded portions 130 of the paper box lid 13 are placed between the upper pressure device 4 and the lower pressure device 5, and the right angle formed by the adjacent folded portions 130 of the paper box corresponds to the right angle on the lower surface of the upper pressure device 4 and the right angle on the upper surface of the lower pressure device 5. That is, the outer surface of the right angle formed by the adjacent folded portions 130 is in contact with the lower surface of the right angle of the upper pressure device 4, and the inner surface of the right angle formed by the adjacent folded portions 130 is in contact with the upper surface of the right angle of the lower pressure device 5. The limiting part 702 will push against the paper box lid 13. By adjusting the limiting part 702, the depth of the U-shaped seat 70 entering the paper box lid 13 is limited, thereby ensuring that the staples can fall in the same position every time they are bound, which can greatly improve the accuracy and consistency of binding.

[0043] In this embodiment, each adjustment part includes multiple adjustment holes 701, which are arranged along the extending direction of the U-shaped seat 70. The adjustment holes 701 are locked to the U-shape by a locking member. That is, by adjusting the locking member at different positions of the adjustment holes 701, the position of the limiter 7 on the base 2 can be adjusted. The locking member in this embodiment can be a locking knob or a screw, and is not limited here. Furthermore, the multiple adjustment holes 701 of each adjustment part are interconnected, which facilitates switching the locking member between different adjustment holes 701.

[0044] Of course, in other embodiments, each adjustment part also includes a U-shaped groove, which extends along the extension direction of the U-shaped seat 70, and the U-shaped groove and the U-shape are locked together by a locking member. In this way, the position adjustment of the limiter 7 on the base 2 can also be achieved.

[0045] It should be noted that the working principle of the right-angle stapler in this embodiment is the same as that of existing traditional staplers. Compared with existing traditional handheld staplers, the innovation of the right-angle stapler in this embodiment lies in: changing the structure of the staple-pushing surface 120 on the staple pusher 12, the structure of the paper-adhering surface on the upper pressure 4, and the structure of the paper-adhering surface on the lower pressure 5.

[0046] Secondly, referring to Figure 10 This utility model also provides a staple, in which the staple is clamped between the pusher 6 and the presser 4 described in the first aspect. Specifically, the staple includes a main body and two legs 93. The main body includes a first inclined portion 90, a connecting portion 92, and a second inclined portion 91. One end of the first inclined portion 90 is connected to one end of the second inclined portion 91 to form an inverted V-shaped structure at 90°. Specifically, the first inclined portion 90 and the second inclined portion 91 are connected by the connecting portion 92. In addition, one leg 93 is vertically fixed to the other end of the first inclined portion 90, and the other leg 93 is vertically fixed to the other end of the second inclined portion 91. The legs 93 are integrally formed with the main body. After binding is completed, the two legs 93 of the staple are respectively inserted into the two adjacent folds 130 of the cardboard box cover 13, while the first inclined portion 90 and the second inclined portion 91 clamp the two adjacent folds 130 of the cardboard box cover 13. Therefore, it can be seen that the staples in this embodiment facilitate the right-angle stapler in this embodiment to complete the binding of the paper box cover 13.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
