[0002] Staplers are commonly used tools in people's daily study, work and life. They bind complicated paper pages into books, so that people no longer have to worry about the order of the pages being messed up. There are many types of existing staplers, which usually have functions such as loading needles, stapling needles, changing the shape of the needles, and anti-skid and anti-noise functions.

[0003] In the invention patent with application number CN201710729433.4, a new stapler is disclosed, including a base, a cavity is provided inside the base, a rotating rod is provided inside the cavity, two second connecting blocks are sleeved on the rotating rod, and two first rotating rods and two second rotating rods are respectively connected to the two second connecting blocks, the upper end of the base is provided with a first opening connected to the cavity, the upper end of the base is provided with a connecting block, the lower end side wall of the connecting block and the bottom end side wall in the cavity are both provided with a first connecting block, the first rotating rod and the second rotating rod are connected to the first connecting block at one end away from the second connecting block, the connecting block passes through the first opening, a hollow groove is provided inside the connecting block, the upper end of the connecting block is provided with a second opening connected to the hollow groove, and a nail box is provided inside the hollow groove. The stapler rotates the rotating rod to move the two second connecting blocks inward or outward at the same time, so as to adjust the distance between the pressing handle and the pressing plate so as to adapt to the binding of books of different thicknesses. The stapler can also limit the position of the staples when binding books, thereby avoiding the deviation of the binding position of the books.

[0004] However, when the stapler is binding documents, test papers, papers, etc. of a certain thickness, the staplers may be deformed during the pressing process due to certain reasons (such as uneven force or the paper is too thick, etc.), so that the deformed staplers are easily stuck in the staple outlet channel, resulting in a staple jam problem, and even causing the staple outlet channel to be blocked. The stuck position is difficult to observe, and the fault point is difficult to quickly and effectively eliminate, thereby reducing work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] Example 1

[0046] See also Figure 1-17 As shown, a stapler provided by an embodiment of the present invention includes a base 1 and a pressing handle 2, a U-shaped backstage clamp 3 is arranged on one side of the base 1, an L-shaped component 4 hinged to the pressing handle 2 is arranged on the upper side of the backstage clamp 3, a stapler 5 is arranged on the inner side of the L-shaped component 4, a sliding handle 501 is arranged on one side of the stapler 5, a first strip hole 401 adapted to the sliding handle 501 is arranged on one side of the L-shaped component 4, and a side of the backstage clamp 3 close to the sliding handle 501 is provided. Two card slots 301 are symmetrically arranged, and card platforms 502 adapted to the card slots 301 are arranged on both sides of the nail remover 5, and second strip holes 402 adapted to the card platforms 502 are arranged on both sides of the L-shaped component 4; when the sliding handle 501 moves along the first strip hole 401, the card platform 502 can move along the second strip hole 402 and be inserted into the card slot 301; a push pin 6 located on one side of the nail remover 5 is arranged on the lower side of the pressing handle 2, and a nail removal channel 7 is arranged on the lower side of the push pin 6.

[0047] In this embodiment, the left side of the L-shaped member is installed on the backstage clamp, and the upper right end of the L-shaped member is rotatably connected to the pressing handle via a connecting shaft, so that the pressing handle can press down the ejector pin.

[0048] Usually, when a stapler is stapling documents, test papers, papers, etc. of a certain thickness, the staples are easily deformed during the downward pressing process due to uneven force or the paper being too thick, causing the deformed staples to get stuck in the staple outlet channel, and the stuck position is difficult to observe and the fault point is difficult to eliminate quickly and effectively.

[0049] The ejector cannot be pressed down again after a staple is stuck. Since the stapler always pushes the staples to the front end (i.e., each time it is pressed, there will always be an intact staple at the stapler outlet. After a staple is stuck, once the stapler handle is pressed again, the ejector will push down the second staple, and the outlet will be blocked by the previous staple. Therefore, pressing the stapler again will cause more and more staples to block the outlet, making it difficult to remove and reducing work efficiency.)

[0050] The embodiment of the present invention provides a stapler capable of quickly removing stuck staples. When a staple is stuck, the sliding handle of the stapler is pushed toward one side of the stapler without releasing the handle, and the stapler port pushes the intact staples on the staple path backwards to a certain distance, so that the passage from the ejector to the stuck staple position is unobstructed. While pushing the sliding handle toward one side, the card table is inserted into the card slot, so that the stapler and the L-shaped member are fixed on the same horizontal line, preventing the stapler from rotating vertically when the stapler's pressing handle is pressed down, thereby ensuring the stability of the structure.

[0051] The pressing handle of the stapler is pressed down to make the ejector pin empty. Under the action of the pressing handle, the ejector pin moves downward along the staple outlet channel and presses the stuck staple out of the staple outlet, thereby effectively eliminating the staple jam fault and improving work efficiency.

[0052] The stapler has a simple structure and is easy to use. The cooperation between the card table and the card slot can prevent the staple remover from rotating up and down during the process of removing the stuck staples, thereby improving the installation stability.

[0053] In order to further improve the stability of the nail remover in the process of removing the stuck nails, the shape of the nail remover 5 is an inverted U-shape, which is convenient for being inserted into the L-shaped component. Both sides of the bottom of the nail remover 5 are provided with sliders 503, and both sides of the bottom of the L-shaped component 4 are provided with slide grooves 403 adapted to the sliders 503. The slide grooves on both sides of the bottom of the L-shaped component are in contact with the sliders on the bottom of the nail remover, so that the nail remover can move along the slide grooves on the L-shaped component. The function of the slide grooves is to prevent the nail remover from being separated from the inner wall of the L-shaped component.

[0054] A U-shaped nail channel 8 is provided on the upper side of the L-shaped member 4, and the nail remover 5 is sleeved on the outer side of the nail channel 8, that is, the L-shaped member and the nail remover form a cavity for accommodating the nail channel, and the nail channel is installed in the cavity, and the intact staples are sleeved on the upper side of the nail channel and can move along the nail channel. A first buckle 404 is provided on one side of the bottom of the L-shaped member 4, and a first through hole 801 is provided on the nail channel 8 on the upper side of the first buckle 404. The first buckle 404 passes through the first through hole 801 and is connected to a first spring 802, and a second buckle 803 connected to the first spring 802 is provided on the nail channel 8. The two ends of the first spring are respectively connected to the first buckle and the second buckle, and are used to connect the L-shaped member and the nail channel, which is convenient for disassembly and installation, and prevents the nail channel from moving as the nail remover pushes the intact staples backward, and has a certain reset elastic force to avoid wear between the components.

[0055] In order to facilitate the resetting of the staple remover and the intact staples and push the staples at the front end to the top of the staple outlet channel, a staple pusher assembly 9 is provided on the upper side of the staple remover 5, and the staple pusher assembly 9 includes an L-shaped fixing portion 901, a connecting rod 902 located at the lower side of the fixing portion 901, and a sliding piece 903 sleeved on the connecting rod 902 and movably connected to the connecting rod 902, a second spring 904 is sleeved on the connecting rod 902, one end of the second spring 904 is fixedly connected to the fixing portion 901, and the other end is abutted against the sliding piece 903, the lower side of the fixing portion 901 is buckled on the staple channel 8, and is detachably connected to the L-shaped component 4, and the sliding piece 903 is fixed to the upper side of the other end of the staple remover 5.

[0056] like Fig.17 As shown, the installation method of the push pin assembly is as follows: one end of the connecting rod 902 close to the sliding sheet 903 is arranged on the upper side of the sliding sheet 903, and a connecting sheet which is sleeved on the connecting rod 902 is arranged above the sliding sheet 903, and a second spring 904 is installed on the push pin connecting rod to facilitate the movement of the sliding sheet 903 on the connecting rod 902 and ensure the sliding sheet is reset.

[0057] The stapler assembly is buckled on the stapler channel. First, push the stapler handle along the stapler slide until it cannot slide. At this time, from the outside, the stapler card table slides into the card slot of the backstage clamp, so that even under external interference, the other parts of the stapler, except the handle, the second spring and the ejector, are completely in a balanced state. From the inside (overall structure diagram), when sliding the stapler handle, since the original moving direction of the stapler is provided by the pusher, under the action of the second spring force of the original pusher, the pusher head always pushes the staples on the stapler channel to the forefront, so that the first pressed stapler is always kept in the stapler outlet channel. The improved internal stapler head pushes the undamaged staples placed on the stapler channel in the opposite direction along the stapler channel. At the same time, the staples also push the stapler head to move in the opposite direction, that is, the second spring on the pusher is compressed. Keeping this state, there is only one stuck staple in the stapler outlet channel, and then the handle is compressed in air, and the staple can be discharged under the action of the ejector. After initially eliminating the problem of staple jam, first release the pressure handle, then release the handle of the stapler. Under the action of the second spring force of the stapler pusher, the stapler pusher head pushes the intact staple forward, the stapler pushes the stapler head to reset, and the stapler card table withdraws from the card slot of the backstage clamp. The first staple needle is reset to the staple outlet channel. The task of eliminating the staple jam is completed.

[0058] Specifically, an L-shaped support member 10 is provided on the upper side of the nail remover 5, and the support member 10 is installed in the L-shaped member 4. A third spring 101 is connected to the upper side of the support member 10, and the upper end of the third spring 101 is connected to the pressing handle 2; strip grooves 201 are provided on both sides of the third spring 101 on the pressing handle 2, and the upper end of the ejector 6 is inserted into the strip groove 201 through a hinge, and is hinged to the pressing handle 2. Here, the hinge can be a pin, which is used to movably connect the ejector to the strip grooves on both sides of the pressing handle. The two ends of the third spring are respectively connected to the support member and the pressing handle. When the pressing handle is pressed down, a compression force is generated on the third spring, so that the third spring has a reset elastic force toward the pressing handle. After the pressing handle is released, the pressing handle is driven to move upward under the action of the reset elastic force of the third spring, thereby improving the convenience of use.

[0059] In order to facilitate the positioning of the moving path of the ejector pin and prevent the ejector pin from deflecting during the pressing process, a top plate 11 is provided on one side of the support member 10. One side of the support member 10 and the top plate 11 enclose a mounting channel 12 for mounting the ejector pin 6. The upper end of the ejector pin is hinged to the pressing handle, and the lower end of the ejector pin is inserted into the mounting channel and can move along the mounting channel. The nail-out channel 7 is provided on the lower side of the mounting channel 12. Through the mounting channel and the nail-out channel, the ejector pin is limited to move in the mounting channel and the nail-out channel, which prevents the ejector pin from deflecting during the pressing process, thereby improving the binding efficiency.

[0060] A sleeve 13 is provided on one side of the top plate 11, and the sleeve 13 is sleeved on one side of the L-shaped component 4 and fixedly connected to the L-shaped component 4 through a pin; U-shaped clamping grooves 131 are provided on both sides of the bottom of the sleeve 13, and clamping protrusions 405 matching the U-shaped clamping grooves 131 are provided on both sides of the L-shaped component 4, and the U-shaped clamping grooves 131 are clamped on the clamping protrusions 405; a first observation port 132 is provided on the sleeve 13, and a second observation port 112 located on one side of the first observation port 132 is provided on the top plate 11, and the first observation port 132 and the second observation port 112 are both provided at the upper end of the nail removal channel 7.

[0061] Here, the U-shaped clamping grooves on both sides of the bottom of the sleeve are clamped on the clamping protrusions on both sides of the L-shaped member, which improves the stability of the installation. A first observation port is provided at the connection between the sleeve near the nail outlet channel and the installation channel, and a second observation port is provided on the top plate near the first observation port, and the first observation port is provided on one side of the second observation port. The first observation port overlaps with the second observation port, and both are located at the nail outlet position at the upper end of the nail outlet channel, which is convenient for observing the nail jamming of the stapler.

[0062] In order to facilitate the ejector to push intact staples to one side of the staple channel, two L-shaped arms 504 extending toward the top plate 11 are symmetrically arranged on the port of the ejector 5, and two L-shaped slots 111 adapted to the corresponding L-shaped arms 504 are arranged on the side of the top plate 11 close to the ejector 5. The L-shaped arms on the ejector can push intact staples backwards to a certain distance, and after ejecting the staples, the sliding handle of the ejector is released, and the L-shaped arms at the front end of the ejector can drive the intact staples to the frontmost staple outlet, so that the first staple at the front end of the staple pushes the L-shaped arms at the front end of the ejector into the L-shaped slot on the top plate, thereby improving the installation stability of the ejector and facilitating the ejector to stably press down the first staple at the staple outlet.

[0063] The backstage clamp 3 is provided with a pin 302 for positioning and rotating the L-shaped member 4, and a fourth spring 303 is provided on one side of the pin 302 (i.e., between the backstage clamp and the L-shaped member), and both ends of the fourth spring 303 are respectively connected to the backstage clamp 3 and the L-shaped member 4. Here, the fourth spring is used to connect the backstage clamp and the L-shaped member, has certain shock absorption and support performance, and improves the installation stability of the L-shaped member.

[0064] Example 2

[0065] See also Figure 18-19As shown, the difference from the above-mentioned embodiment is that a nail plate 14 is installed on the base 1, and the nail plate 14 is arranged on the lower side of the nail outlet channel 7, and a shock-absorbing assembly 141 is connected to the lower side of the nail plate 14; the function of the top plate is mainly to locate the downward position of the staples, and when the staples are discharged, the ejector pin is compressed, and when the staples are driven to be discharged, it is pressed down to the nail plate to prevent it from pressing on the base and causing certain damage to the base. The shock-absorbing assembly under the top plate has a certain shock-absorbing performance to prevent the nail plate from damaging the base due to excessive downward pressure from the ejector pin. Specifically, the shock-absorbing assembly includes a ring located on the base, and a shock-absorbing connecting rod vertically connected to the lower side of the top plate is connected inside the ring, and a shock-absorbing spring is sleeved inside the shock-absorbing connecting rod.

[0066] A strip mounting groove is provided on one side of the base 1 close to the backstage clamp 3, and scales are provided on both sides of the strip mounting groove. A U-shaped position correction part 15 which can be movably connected along the strip mounting groove is installed on the strip mounting groove, and an inverted cone-shaped limit spring 151 is connected to the lower side of the position correction part 15, and the limit spring 151 is installed in the strip mounting groove.

[0067] Specifically, the base includes an upper base and a lower base, and the upper base and the lower base are combined to form a cavity, so that the shock absorbing component and the limit spring can be installed in the cavity.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
