Dual mode stapler

Abstract

This invention relates to a dual-mode stapler, comprising a first base, a second base, a needle cartridge assembly, a pressure handle assembly, and a locking mechanism. The second base, needle cartridge assembly, and pressure handle assembly are pivotally connected to the first base. The locking mechanism includes an operating member and a spring member. The operating member is disposed on one of the bases and can slide between a locked position and an unlocked position along a sliding direction. The spring member is disposed between the operating member and the base on which the operating member is located. When the operating member is in the locked position, the operating member engages with the other base, allowing the second base and the needle cartridge assembly to maintain an appropriate distance, enabling the stapler to be used in a needle-retracting mode. When the operating member is in the unlocked position, the second base pivots away from the needle cartridge assembly and is in an open state, enabling the stapler to be used in a non-needle-retracting mode.

Description

Technical Field

[0001] This invention relates to a handheld binding tool, and more particularly to a dual-mode stapler. Background Technology

[0002] A stapler is a hand tool that uses staples to bind paper. It includes components such as a base, a staple cartridge, and a pressure handle. The staple cartridge and pressure handle are pivotally connected to the base. By pressing the pressure handle, the staple cartridge is rotated relative to the base, causing the staple cartridge to move closer to the base. This allows the staples in the staple cartridge to pass through the object to be bound, and the staple retraction mechanism on the base bends and retracts the tips of the staples, thus completing the binding process.

[0003] To facilitate operation, there are many different types of staplers on the market that reduce the force required to press the stapler through different linkage designs. For example, in one type of existing stapler, multiple rods are designed with a pressure handle, and the needle cartridge and some rods of the pressure handle are pivotally connected to different positions on the base to form lever arms of different lengths to transmit force, thereby achieving the effect of saving effort.

[0004] However, if one wishes to switch this existing stapler to a non-retrieval mode, that is, to unfold the base relative to the staple cartridge and the pressure handle, and simply operate the pressure handle to allow the staples in the staple cartridge to pass through the binding material and insert and fix it to another object, without retrieving the staples through the staple retraction mechanism on the base, the pressure handle and the staple cartridge will also move and unfold relative to each other as the base unfolds, making it impossible to staple. Therefore, it cannot be used in a non-retrieval mode, and its uses are rather limited. Summary of the Invention

[0005] In order to solve the problem that existing staplers cannot be used in a non-retrieval mode and have limited uses, the present invention aims to propose a dual-mode stapler with a detachable base design that can be used normally in both non-retrieval and retrieval modes.

[0006] The dual-mode stapler proposed by this invention to solve the technical problem comprises:

[0007] Two bases, namely a first base and a second base, wherein the second base is pivotally connected to the first base;

[0008] A needle cartridge assembly, which is pivotally coupled to the first base and spaced apart from the second base;

[0009] A pressure handle assembly, pivotally coupled to the first base and spaced apart from the second base; and

[0010] A locking mechanism, which includes

[0011] An operating element, disposed on one of the bases, and slidable along a sliding direction between a locked position and an unlocked position; and

[0012] An elastic member is disposed between the operating member and the base on which the operating member is disposed, and the elastic member can elastically deform to drive the operating member to slide toward the locking position;

[0013] When the operating element is in the locked position, it is engaged with the other base; when the operating element is in the unlocked position, it is disengaged from the other base, allowing the second base to pivot relative to the first base in a direction away from the needle cartridge assembly and enter an open state.

[0014] The improved effects of the technical means of the present invention are as follows: When the present invention is applied to any stapler that needs to pivot different components at different positions on the base, different components are pivoted through the first base, and when switching to the non-retracting mode, the second base is pivoted to the open state in a direction away from the needle cartridge assembly. With the locking and unlocking of the locking mechanism, it can be freely switched between the retracting mode and the non-retracting mode, thereby providing a dual-mode stapler with more diverse and unrestricted uses.

[0026] To gain a detailed understanding of the technical features and practical effects of the present invention, and to enable its implementation, the preferred embodiments shown in the figures are further described in detail below:

[0027] like Figures 1 to 3 As shown, a first preferred embodiment of the dual-mode stapler of the present invention includes two bases, a needle cartridge assembly 30, a pressure handle assembly 40, and a locking mechanism 50. The two bases are a first base 10 and a second base 20, the second base 20 being pivotally connected to the first base 10, the needle cartridge assembly 30 and the pressure handle assembly 40 being pivotally connected to the first base 10, and the locking mechanism 50 being disposed on one of the bases.

[0028] like Figure 2A and Figure 2B As shown, the first base 10 has a plurality of spaced-apart pivot positions. In the first preferred embodiment of the present invention, the plurality of pivot positions include a first pivot position 12, a second pivot position 13 and a third pivot position 14, which are respectively used for pivoting the second base 20, the needle cartridge assembly 30 and the pressure handle assembly 40. The first base 10 includes two parallel mounting plates 101 and a connecting plate 102 connected between the two mounting plates 101. The first pivot position 12, the second pivot position 13 and the third pivot position 14 are formed on the two mounting plates 101.

[0029] like Figure 2A and Figure 2B As shown, specifically, each pivot position includes two pivot holes, which are respectively provided through the two mounting plates 101. The two pivots 72 and 73 are respectively inserted through the two pivot holes and the component to be pivoted, or two pivot posts 74 are formed on the component to be pivoted and inserted into the two pivot holes, which can achieve the pivoting effect. In other embodiments, the pivoting method can also be to form pivot posts and pivot holes on the first base 10, the second base 20, the needle box assembly 30 and the pressure handle assembly 40, respectively. As long as the pivoting effect can be achieved, the connection form is not limited to the above.

[0030] like Figure 2B As shown, the second base 20 is elongated and has two opposite ends. One end of the second base 20 is pivotally connected to the first pivot position 12. Specifically, the second base 20 has two extension arms at one end, and the two mounting plates 101 are located between the two extension arms of the second base 20. The first base 10 also includes a rear seat 16, which covers a portion of the connecting plate 102 and the two mounting plates 101. The pivot 72 passes through the two extension arms of the second base 20, the rear seat 16, and the two mounting plates 101 to achieve the pivoting effect.

[0031] like Figure 2B As shown, the second base 20 has a needle-retracting structure at the other end to bend the staple and retract the staple. In the first preferred embodiment of the present invention, the second base 20 has a needle groove 23 at the end away from the first base 10. The needle groove 23 has a groove of a specific shape to bend and retract the end of the staple needle.

[0032] like Figure 2A As shown, the needle holder assembly 30 and the pressure handle assembly 40 also have elongated structures and are pivotally connected to the first base 10 at one end respectively. The needle holder assembly 30 includes a central groove 31 for receiving staples, and the pressure handle assembly 40 includes a pressure handle 42. The pressure handle 42 can be pressed and pivoted relative to the first base 10 to strike the staples, push the staples out of the central groove 31 and press them into the groove of the needle groove plate 23.

[0033] In addition, such as Figure 2A As shown, in the first preferred embodiment of the present invention, the pressure handle assembly 40 further includes an auxiliary pressure handle 41, a force-saving lever 80, and an outer cover 43. The auxiliary pressure handle 41 is pivotally connected to the third pivot position 14 via the pivot 74. The pivot 73 passes through two opposing pressure handle pivot holes 421 on the pressure handle 42, two opposing needle cartridge pivot holes 32 on the needle cartridge assembly 30, and two pivot holes on the second pivot position 13, thereby pivotally connecting the pressure handle 42 and the needle cartridge assembly 30 together to the second pivot position 13. The two ends of the force-saving lever 80 are respectively pivotally connected to the auxiliary pressure handle 41 and the pressure handle 42, thereby forming lever arms of different lengths to transmit force, achieving a force-saving effect. The outer cover 43 is made of plastic and covers the auxiliary pressure handle 41 for convenient operation. In short, the pressure handle assembly includes a pressure handle 42 and an auxiliary pressure handle 41 connected together, which are connected by the force-saving lever 80. The pressure handle 42 is pivotally connected to the needle cartridge assembly 30 at the second pivot position 13, and the auxiliary pressure handle 41 is pivotally connected to the third pivot position 14.

[0034] like Figure 3As shown, the locking mechanism 50 includes an operating member 51 and an elastic member 52. In the first preferred embodiment of the present invention, the operating member 51 is slidably disposed in the second base 20. Specifically, the second base 20 includes a body 21 and a top cover 22. A space is formed between the body 21 and the top cover 22 for the operating member 51 to be disposed and slide therein. The operating member 51 can slide along a sliding direction S between a locked position and an unlocked position. Specifically, the body 21 is a plastic component, and the top cover 22 is a metal component.

[0035] like Figure 3 and Figure 4 As shown, in a first preferred embodiment of the present invention, the operating member 51 includes a locking portion 511, which is located at one end of the operating member 51 near the first base 10. The first base 10 includes a locking hook 11, which extends from the end of the connecting plate 102 near the operating member 51 by bending. Figure 4 As shown, when the operating member 51 is in the locked position, the engaging part 511 is located between the engaging hook 11 and the needle box assembly 30 and is engaged with the engaging hook 11.

[0036] like Figure 3 and Figure 4 As shown, the elastic element 52 is disposed between the second base 20 of the operating member 51. In the first preferred embodiment of the present invention, the elastic element 52 is a compression spring, which is disposed between the seat 21 and the upper cover 22 along the sliding direction S. The operating member 51 is located between the elastic element 52 and the first base 10. The two ends of the elastic element 52 abut against the operating member 51 and the seat 21 respectively, and can stably drive the operating member 51 toward the locking position with elastic restoring force.

[0037] The dual-mode stapler of this invention can be used in two modes: a staple removal mode and a staple non-removal mode. Figure 4 As shown, in the retractable mode, the operating member 51 is pushed to the locking position by the elastic member 52. At this time, the operating member 51 on the second base 20 is engaged with the first base 10, which can prevent the second base 20 from pivoting away from the needle cartridge assembly 30 relative to the first base 10, thereby fixing the two bases and making the second base 20 in a closed state. This ensures that an appropriate distance is maintained between the second base 20 and the needle cartridge assembly 30. In this way, the object to be bound can be placed between the needle groove plate 23 of the needle cartridge assembly 30 and the second base 20, and the pressure handle assembly 40 is pressed to make the staples in the needle cartridge assembly 30 pass through the object to be bound. The staples are bent and retracted through the groove of the needle groove plate 23, thus completing the binding.

[0038] And such Figure 5As shown, by operating the operating member 51 to slide from the locked position to the unlocked position, the operating member 51 is disengaged from the first base 10. The engaging portion 511 of the operating member 51 is no longer engaged with the engaging hook 11 of the first base 10. At this time, the second base 20, which is no longer restricted, can be pivoted relative to the first base 10 in a direction away from the needle cartridge assembly 30, and as... Figure 6 The device is in an open state, and can then be switched to the non-retractable needle mode. By placing the object to be bound between the needle cartridge assembly 30 and another object, and pressing the handle assembly 40, the staples in the needle cartridge assembly 30 pass through the object to be bound and are inserted into the other object, thus binding the object to the other object.

[0039] Compared to existing staplers where the needle cartridge and pressure handle are pivotally connected to different positions on the base, if the stapler wants to switch to a non-retractable mode, the needle cartridge and pressure handle will unfold together when the base is opened relative to the needle cartridge and pressure handle, making it impossible to use in the non-retractable mode. This invention splits the base into a first base 10 and a second base 20, so that the needle cartridge assembly 30, the pressure handle 42 and the auxiliary pressure handle 41 of the pressure handle assembly 40 are combined with the first base 10. With the locking and unlocking of the locking mechanism 50, when switching to the non-retractable mode, the second base 20 pivots relative to the first base 10 in a direction away from the needle cartridge assembly 30, which can prevent the pressure handle 42 and the auxiliary pressure handle 41 from unfolding together. In the retractable mode, the locking mechanism 50 restricts the operation of the operating member 51, so that the second base 20 and the needle cartridge assembly 30 maintain an appropriate distance, thereby allowing normal switching between the retractable mode and the non-retractable mode.

[0040] Furthermore, the design of this invention can also be applied to situations where the pressure handle 42 and the auxiliary pressure handle 41 share the same pivot; such as... Figure 2A As shown, the first base 10 is also pivotally connected to a rear cover 62 to cover the structure in which the first base 10 is pivotally connected to the needle cartridge assembly 30 and the pressure handle assembly 40. The pivot point of the rear cover 62 is different from that of the needle cartridge assembly 30, the pressure handle 42 and the auxiliary pressure handle 41. Since the existing stapler only contains a single base, even if the pivots of the needle cartridge and the pressure handle are the same, when switching to the non-retractable mode and unfolding the base relative to the needle cartridge, the rear cover 62 will also be driven to move relative to the needle cartridge and the pressure handle, thereby jamming each other or jamming with other components of the stapler, hindering the unfolding of the base.

[0041] In contrast, the present invention, through the structural configuration of the first base 10, the second base 20 and the locking mechanism 50, pivots the rear cover 62 to the first base 10, and when switching to the non-retractable needle mode, the second base 20 pivots away from the needle cartridge assembly 30, which can also prevent the rear cover 62 from being moved by the mechanism and avoid the rear cover 62 from getting stuck with the needle cartridge assembly 30, the pressure handle assembly 40 or other components of the stapler.

[0042] Therefore, the present invention can be applied to any stapler that requires different components to be pivotally connected at different positions on the base. Different components are pivotally connected through the first base 10, and when switching to the non-retractable mode, the second base 20 is pivoted to the open state to unfold. With the locking mechanism 50 locking and unlocking, it can be freely switched between the retractable mode and the non-retractable mode. This avoids the problem that existing staplers cannot be used in the non-retractable mode or that the mode switching is hindered, thereby providing a dual-mode stapler with more diverse and unrestricted uses.

[0043] Furthermore, such as Figure 3 As shown, the operating member 51 also includes a ramp 512, which is formed on the engaging portion 511 and located in the direction from the second base 20 toward the needle cartridge assembly 30. Specifically, with Figure 4 Taking the perspective of [the location] as an example, the two ends of the second base 20 are defined as a front end and a rear end, respectively, close to [the location]. Figure 4 On the left and right sides, the rear end of the second base 20 is pivotally connected to the first base 10, and the inclined surface 512 faces the rear end of the second base 20. Figure 4 bottom side facing Figure 4 On the top side, the inclined surface 512 gradually slopes toward the front end of the second base 20.

[0044] like Figure 7 and Figure 8 As shown, when switching from the non-retractable needle mode to the retractable needle mode, when the second base 20 is pivoted from the open state toward the needle magazine assembly 30, the locking hook 11 of the first base 10 abuts against the inclined surface 512 of the operating member 51, thereby pushing the operating member 51 to slide toward the unlocked position and causing the elastic member 52 to elastically deform until the locking part 511 of the operating member 51 passes past the locking hook 11 of the first base 10 and is locked again by the locking hook 11 and positioned between the locking hook 11 and the needle magazine assembly 30, thus switching the retractable needle mode.

[0045] With the design of the inclined surface 512, when switching the retraction needle mode, there is no need to apply additional force to pull the operating member 51. Simply pivoting the second base 20 from the open state will directly push the operating member 51, which has been pushed to the locked position by the elastic member 52, open it and reset the second base 20, thus improving operational convenience. In other embodiments, the number and shape of the inclined surface 512 vary depending on the shape of the engaging part 511, and are not limited to the first preferred embodiment of the present invention.

[0046] Furthermore, in other embodiments, the structure in which the first base 10 engages with the operating member 51 and pushes against the inclined surface 512 is not limited to using the locking hook 11. As long as the first base 10 can engage with the locking portion 511 of the operating member 51 in the needle retraction mode, and can push against the inclined surface 512 and push the operating member 51 towards the unlocking position when switching from the non-needle retraction mode to the needle recovery mode, the invention can achieve multiple uses and the aforementioned effect of further improving operational convenience.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the seat body 21 of the second base 20 includes a connecting hole 211. The connecting hole 211 is provided through the seat body 21 in a direction intersecting the sliding direction S, thereby connecting the space between the seat body 21 and the upper cover 22. Specifically, the connecting hole 211 is provided in a direction perpendicular to the sliding direction S. In this way, when switching to the non-pin retraction mode, the user can insert his finger through the connecting hole 211 between the seat body 21 and the upper cover 22 and apply force to push the operating member 51 to slide. With the design that the operating member 51 is hidden inside the second base 20, the operation is still convenient.

[0048] In addition, such as Figure 2B As shown, in the first preferred embodiment of the present invention, the dual-mode stapler further includes a bottom cover 63, which is attached to the bottom of the second base 20 and covers both sides of the pivot 72 of the first base 10 and the second base 20. The bottom cover 63 can limit the pivot 72 and prevent the pivot 72 from falling out of the first base 10 and the second base 20. The bottom cover 63 is provided with a through hole, which is linearly opposite to and communicates with the connecting hole 211, and can maintain the function of the connecting hole 211.

[0049] Furthermore, such as Figures 3 to 5 As shown, the operating member 51 is also provided with an operating hole 513. The operating hole 513 is formed on the operating member 51 along a direction intersecting the sliding direction S and is located within the range of the connecting hole 211. Specifically, the operating hole 513 is set along a direction perpendicular to the sliding direction S. After the user's finger passes through the connecting hole 211, it can be inserted into the operating hole 513 of the operating member 51, thereby applying force along the sliding direction S to push the operating member 51 to slide along the sliding direction S, making the operation more convenient and effortless. In other embodiments, the operating hole 513 can also be replaced by other forms such as grooves or notches for the user's fingers to insert and operate.

[0050] like Figure 9 and Figure 10The second preferred embodiment of the dual-mode stapler of the present invention is shown. The difference between the second and first preferred embodiments of the present invention is that the operating member 51A of the locking mechanism 50A is disposed on the surface of the second base 20A, and the first base 10A does not have the locking hook 11. When the operating member 51A is in the locked position, the locking part 511A of the operating member 51A is directly engaged with the connecting plate 102A of the first base 10.

[0051] like Figure 9 and Figure 10 As shown, the engaging portion 511A of the operating member 51A is located between the two mounting plates 101A and can engage with the connecting plate 102A. The second base 20A has at least one sliding groove 24 formed on its upper surface. The sliding groove 24 is arranged along the sliding direction S. The operating member 51A is disposed on the sliding groove 24 and can move along the sliding groove 24 between the locked position and the unlocked position. The sliding groove 24 restricts the operating member 51A to slide in the sliding direction S, so that the operating member 51A can be disposed outside the second base 20A, allowing personnel to directly operate the operating member 51A from the outside of the second base 20A and to visually inspect the status of the operating member 51A.

[0052] The number of the sliding grooves 24 can be determined according to the space and sliding stability requirements of the second base 20. In the preferred embodiment of the present invention, there is no particular limitation. In other embodiments, the sliding grooves 24 can also be provided on the side or bottom surface of the second base 20, depending on the desired position of the operating member 51A. For example, the operating member 51A can also be provided on the side or bottom surface of the second base 20, or even cover the second base 20, and is not limited to the second preferred embodiment of the present invention.

[0053] like Figure 9 and Figure 10 As shown, the operating component 51A adopts a hollow design. Specifically, the main body 510 of the operating component 51A is spaced apart from the engaging portion 511A. The operating component 51A also includes two spaced-apart connecting arms 514. One end of each connecting arm 514 is integrally connected to the main body 510. The first base 10A is located between the two connecting arms 514, and each mounting plate 101A of the first base 10A is provided with a notch 103. The two connecting arms 514 pass through the notches 103 of the two mounting plates 101A and are integrally connected to the engaging portion 511A.

[0054] In addition, such as Figure 9 and Figure 10As shown, the elastic element 52A is still a compression spring. The two ends of the elastic element 52A abut against the engaging part 511A of the operating element 51A and the second base 20A, respectively. The second base 20A is also provided with a groove 25 for mounting the elastic element 52A. The operating element 51A is also provided with a protrusion 515 along a direction intersecting the sliding direction S, so that when operating, force can be applied along the sliding direction S to push against the protrusion 515, thereby pushing the operating element 51A, making the operation more convenient and less strenuous.

[0055] Preferably, the locking mechanism 50A further includes at least one bolt 53, and the operating member 51A is provided with at least one elongated hole 54, which extends parallel to the slide groove 24 along the sliding direction S. The bolt 53 passes through the elongated hole 54 and is screwed into and positioned on the second base 20A. When the operating member 51A slides relative to the second base 20A along the sliding direction S, the operating member 51A moves relative to the bolt 53 and the second base 20A via the elongated hole 54. Through the bolt 53 and the elongated hole 54, in conjunction with the aforementioned slide groove 24, a limiting effect can be provided, allowing the operating member 51A to slide stably within a specific stroke provided by the elongated hole 54 in the sliding direction S.

[0056] like Figure 11 The third preferred embodiment of the dual-mode stapler of the present invention is shown. The difference between the third and fourth preferred embodiments is that the elastic member 52B is integrally formed with the operating member 51B and can be elastically bent relative to the operating member 51B. The end of the elastic member 52B away from the operating member 51B abuts against a stop seat 26 provided on the second base 20.

[0057] Specifically, the elastic element 52B is a thin sheet that can be bent relative to the operating element 51B. When force is applied to slide the operating element 51B toward the unlocked position, the elastic element 52B is blocked by the stop seat 26, compressed, and bent. After the force is stopped, the elastic element 52B can return to its original position, driving the operating element 51B to slide toward the locked position, thereby providing another form of elastic element 52B. In addition to compression deformation, in other embodiments, the elastic element can also be a tension spring, torsion spring, or other elastic member depending on the structure of the first base 10 and the second base 20, as long as it can push the operating element 51 toward the locked position with elastic restoring force. The form of the elastic element is not limited to the above.

[0058] In addition to the three preferred embodiments described above, in other embodiments, the locking mechanism 50 can also be disposed on the first base 10. When the operating member 51 is in the locked position and the unlocked position, it engages with or disengages from the second base 20. This also achieves the effect of the present invention in avoiding the inability to switch to the non-pin-retracting mode and having more diverse uses. In the three preferred embodiments described above, the operating member 51 of the locking mechanism 50 is disposed on the elongated second base 20. It can directly slide along the length direction of the second base 20 as the sliding direction S and form an accommodating space for the operating member 51 and the elastic member 52. The design is relatively simple, and the design of the locking mechanism 50 does not require much additional space.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.

6. The dual-mode stapler as described in any one of claims 1 to 5, characterized in that, The second base includes a base and a top cover, and the operating element is located between the base and the top cover.

7. The dual-mode stapler as described in claim 6, characterized in that, The second base has a connecting hole that extends through the base along a direction intersecting the sliding direction, thereby connecting the space between the base and the top cover.

8. The dual-mode stapler as described in claim 7, characterized in that, The operating member is provided with an operating hole, which is formed on the operating member along a direction intersecting the sliding direction and is located within the range of the connecting hole.

9. The dual-mode stapler as described in any one of claims 1 to 5, characterized in that, The surface of the second base has at least one slide rail arranged along the sliding direction. The operating member is disposed on the slide rail of the second base and can slide along the slide rail between the locked position and the unlocked position.

10. The dual-mode stapler as described in claim 9, characterized in that, The operating member has at least one elongated hole that is parallel to the slide rail. The locking mechanism includes at least one bolt that passes through the elongated hole and is positioned on the second base. The operating member moves relative to the bolt and the second base through the elongated hole.
