[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions in the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0039] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0040] In the related art, a rotary stapler generally includes a base, a movable plate, and a press-binding mechanism, wherein one end of the movable plate is hinged on the base, and the other end of the movable plate extends upward at an angle, and the press-binding mechanism is rotatably arranged on the upper end of the movable plate. When binding paper documents (such as printed booklets or booklets cut and printed from other papers, etc.), taking center seam binding as an example, staples are loaded into the press-binding mechanism, and then the paper documents to be bound are placed between the base and the movable plate, and the press-binding mechanism is rotated to the horizontal direction so that the length direction of the staples is parallel to the extension direction of the center seam of the paper documents, and finally the press-binding mechanism is pressed, thereby fastening the staples to the paper documents and binding the paper documents.

[0041] When binding paper documents of different specifications (such as A3, A4 and other sizes), the binding is usually done based on the staff's estimated size or personal feeling. As a result, it is difficult to ensure the neatness of the paper documents after binding, especially for the center seam binding of paper documents. The staples are difficult to be evenly distributed on the center seam of the paper, resulting in poor binding effect of the paper documents, causing some paper to fall off easily in the bound paper documents; and when binding multiple documents of the same batch, it is necessary to estimate the binding position of each paper document one by one, making it difficult to grasp the neatness of the binding positions of the staples on the multiple paper documents, and the binding efficiency is low.

[0042] Therefore, the present application provides a stapler, by setting scale marks and limit pieces on the base, and setting a locking piece on the limit piece; when the stapler is used, the position of the limit piece is adjusted according to the specifications of the paper documents (such as A3, A4, etc.) and with reference to the scale marks, and then the limit piece is locked in the current position by the locking piece, and then the distance between the limit piece and the pressing binding mechanism is adjusted; then, the paper document only needs to be placed between the base and the movable plate, so that the side of the paper document leans against the limit piece, and then the stapler can be stapled. The binding mechanism is directly pressed down to bind the staples on the paper document, so that the staples are in a better binding position on the paper document, and the staples are evenly distributed at the middle seam of the paper document with reference to the scale marks, so that the force on the binding part of the paper document is more uniform, the binding effect is good, and the operation process is convenient; for multiple paper documents of the same batch, the same operation can be performed, so that the binding effect of the multiple paper documents is more neat, and the binding efficiency is high, which solves the technical problem of poor binding effect of paper documents in the prior art.

[0043] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0044] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a stapler, including a base 100, a movable plate 200, a limiting assembly 300 and a pressing binding mechanism 400; one end of the movable plate 200 is hinged on the base 100, and the other end of the movable plate 200 extends upward at an angle, and the pressing binding mechanism 400 is rotatably arranged on the movable plate 200; the limiting assembly 300 includes a limiting member 310 and a locking member 320 arranged on the limiting member 310, and the limiting member 310 is arranged on the base 100, and Slide relative to the base 100 to adjust the distance between the limit member 310 and the press binding mechanism 400. The limit member 310 is used to contact the side of the paper document to position the paper document. The locking member 320 is used to lock the limit member 310 in the current position. The base 100 or the movable plate 200 is provided with scale marks 500, which are distributed along the sliding direction of the limit member 310. The scale marks 500 are used to provide an indication of the position of the limit member 310.

[0045] Specifically, the base 100 is in a long strip structure, the lower end of the movable plate 200 is close to one end of the base 100, and the lower end of the movable plate 200 is hinged to the upper surface of the base 100, and the hinge portion of the movable plate 200 is provided with a torsion spring or a spring, so that the torsion spring or the spring can push the movable plate 200 to rotate away from the base 100, ensuring that when the stapler is in the initial state, there is a gap between the movable plate 200 and the base 100. The other end of the movable plate 200 extends upward at an angle, and the upper end of the movable plate 200 is close to the other end of the base 100, so that when the paper documents are placed between the base 100 and the movable plate 200, the paper documents have sufficient placement space, which is convenient for staplers to be bound on the paper documents.

[0046] Exemplarily, the press binding mechanism 400 includes a storage seat and a pressing shell, one end of the storage seat is rotatably set on the upper end of the movable plate 200, and the interior of the storage seat is used to store staples, and the storage seat has a staple outlet at one end facing the movable plate 200; the pressing shell is rotatably connected to the storage seat, and the pressing shell is provided with a push plate, which is correspondingly arranged above the staple outlet; when the pressing shell is pressed down, the push plate can push the staples in the storage seat out of the staple outlet, and enable the staples to be stapled to the paper document.

[0047] It should be noted that the stopper 310 is slidably disposed on the base 100 along the length direction of the base 100, so that after the stopper 310 is slid and locked by the locking member 320, the distance between the stopper 310 and the pressing binding mechanism 400 can be adjusted and temporarily locked. When a paper document is placed in the gap between the base 100 and the movable plate 200, the stopper 310 can limit the amount of insertion of the paper document.

[0048] like Figure 2As shown, specifically, the base 100 is provided with scale marks 500, and the scale marks 500 are distributed along the length direction of the base 100, so that the position of the limiter 310 can be adjusted with reference to the scale marks 500, so that the limiter 310 is adjusted with higher accuracy. For example, the position where the limiter 310 needs to be placed for common paper specifications can also be indicated on the scale marks 500, further facilitating the position adjustment of the limiter 310, such as marking A3, A4, etc. on the scale marks 500.

[0049] In addition, in other embodiments, scale marks 500 may be disposed on the upper surface of the movable plate 200 to facilitate the user to view the scale marks 500 during use.

[0050] When the paper document is center-bound, the position of the limiter 310 is adjusted according to the specifications of the paper document (such as A3, A4, etc.) and with reference to the scale mark 500, and then the limiter 310 is locked in the current position by the locking member 320, so that there is a better distance between the limiter 310 and the pressing binding mechanism 400. Then, the paper document only needs to be placed between the base 100 and the movable plate 200, so that the side of the paper document leans against the limiter 310, and the pressing binding mechanism 400 can be directly pressed down to bind the staples on the paper document, so that the staples are in a better binding position on the paper document, the binding effect is good, and the operation process is convenient. For multiple paper documents of the same batch, the same operation can be performed, so that the binding effect of the multiple paper documents is relatively neat, and the binding efficiency is high, which solves the technical problem of poor binding effect of paper documents in the prior art.

[0051] like Figure 2 As shown, in some embodiments, a track groove 110 extending along the sliding direction of the limit member 310 is provided on the upper surface of the base 100, and the limit member 310 is partially slidably set in the track groove 110, and the locking member 320 is used to lock the limit member 310 at different positions in the track groove 110.

[0052] In the embodiment of the present application, the track groove 110 is an upwardly open structure, and the limiter 310 is vertically arranged and the lower part is inserted into the track groove 110. When the limiter 310 slides, the track groove 110 can guide the limiter 310, so that the limiter 310 is more stable during the adjustment process, and the use effect of the limiter 310 is improved.

[0053] like Figure 2 and Figure 3As shown, in some embodiments, there are two track grooves 110, and the two track grooves 110 are respectively located on opposite sides of the movable plate 200. The limiting member 310 includes a connecting portion 311 and two supporting portions 312 connected to the connecting portion 311. One end of the track groove 110 extends toward the side of the base 100 and is connected to the side surface of the base 100. The supporting portion 312 is correspondingly inserted into the track groove 110 and rotated relative to the track groove 110 to receive the supporting portion 312 in the track groove 110.

[0054] Specifically, in the position-limiting member 310, the two support portions 312 are both vertically extended and respectively located on opposite sides of the movable plate 200, and the lower ends of the support portions 312 are inserted into the track groove 110, so that the support portions 312 can slide along the track groove 110. The connecting portion 311 is located above the movable plate 200, and the two ends of the connecting portion 311 are respectively connected to the upper ends of the two support portions 312. Specifically, the connecting portion 311 and the support portion 312 are integrally formed. Of course, the connecting portion 311 can also be connected to the support portion 312 by welding or bonding, so that the position-limiting member 310 as a whole is an inverted U-shaped structure mounted on the movable plate 200. At this time, the locking member 320 is arranged on the support portion 312, so that the locking member 320 can lock the support portion 312 at different positions in the track groove 110.

[0055] When the stapler is in use, the sliding movement of the plurality of support parts 312 can be controlled simultaneously by moving the connecting part 311, and then the support part 312 is locked by the locking part 320, thereby adjusting the position of the limiter 310. Then, the paper document can be abutted against the support part 312 to position the paper document, thereby improving the binding effect of the paper document.

[0056] After the stapler is used, the stopper 310 can be moved to the side of the base 100, and then the stopper 310 can be rotated so that the support part 312 is horizontal, and then the stopper 310 can be slid toward the side of the base 100 so that the support part 312 is correspondingly stored in the track groove 110, thereby folding or storing the stopper 310. This reduces the possibility of obstruction to the reset of the pressing binding mechanism 400, and also reduces the possibility of damage to the stopper 310 due to external force during the storage of the stapler.

[0057] In other embodiments, the limiting member 310 may be set to other shapes; the height of the connecting portion 311 may be greater than the height of the pressing binding mechanism 400. The two supporting portions 312 may be divided to limit the paper document from different positions respectively; on this basis, the track grooves 110 may be set to other numbers, in which case the number of supporting portions 312 corresponding to the track grooves 110 is set to be multiple.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, the bottom of the track groove 110 has a sliding channel 120 extending along the length direction of the track groove 110, and the width of the sliding channel 120 is greater than the width of the track groove 110; a cylindrical connector 313 is provided at the lower end of the support portion 312, and the cylindrical connector 313 is slidably set in the sliding channel 120.

[0059] In the embodiment of the present application, one end of the sliding channel 120 also extends toward one side of the base 100 and is connected to the side surface of the base 100, so that the extension trajectory of the sliding channel 120 is consistent with the extension trajectory of the track groove 110, and the sliding channel 120 and the track groove 110 are combined into a stepped groove structure with the small end opening upward.

[0060] It should be noted that the cylindrical connector 313 is integrally formed with the support portion 312. Of course, the cylindrical connector 313 can also be fixed to the lower end of the support portion 312 by welding or bonding. The cylindrical connector 313 is slidably disposed in the sliding channel 120, and the axial direction of the cylindrical connector 313 is perpendicular to the length direction of the sliding channel 120. The length of the cylindrical connector 313 is greater than the width of the track groove 110, so that the cylindrical connector 313 can move in the sliding channel 120 and can also rotate in the sliding channel 120.

[0061] During the overall movement of the stopper 310, the sliding channel 120 can limit the cylindrical connector 313, so that the lower end of the support portion 312 is not easily separated from the track groove 110, further improving the stability of the stopper 310 as a whole during the position adjustment process, and improving the use effect. In addition, when it is necessary to store the stopper 310, it is only necessary to move the stopper 310 as a whole to the side of the base 100, and then rotate the stopper 310 as a whole and move it toward the side of the base 100, so that the support portion 312 is horizontally inserted into the sliding channel 120, thereby achieving the purpose of partially storing the stopper 310.

[0062] like Figure 3 and Figure 4 As shown, in some embodiments, a plurality of positioning holes 121 spaced apart along the sliding direction of the limiting member 310 are provided at the bottom of the sliding channel 120, and the locking member 320 is used to cooperate with at least one positioning hole 121 to lock the limiting member 310 at the current position.

[0063] When in use, the limit member 310 can be moved along the track groove 110, and then the locking member 320 is engaged with the positioning hole 121 at the current position to lock the limit member 310 at the current position so that the limit member 310 abuts against the side of the paper document, thereby improving the convenience of the paper document binding process.

[0064] In addition, the spacing of the multiple positioning holes 121 at the bottom of the sliding channel 120 can be reasonably arranged according to the needs. For example, the position of at least one positioning hole 121 corresponds to the word A3 on the scale mark 500; the position of at least one positioning hole 121 corresponds to the word A4 on the scale mark 500. When the limiter 310 moves to the position corresponding to the word A3 or A4 on the scale mark 500, the locking member 320 can cooperate with the positioning hole 121 at the position, and then the limiter 310 is locked at the position, which is convenient for users to bind paper documents of common specifications, and further improves the convenience of using the stapler.

[0065] like Figures 3 to 5 As shown, in some embodiments, the locking member 320 includes a positioning pin 321, an elastic member 322 and a control member 323. The positioning pin 321 is slidably set on the support portion 312. The elastic member 322 is set in the support portion 312 and is used to push the positioning pin 321 to move toward the bottom of the sliding channel 120 to be inserted into the positioning hole 121. The control member 323 is set on the connecting portion 311 and is used to control the positioning pin 321 to move away from the positioning hole 121.

[0066] In the embodiment of the present application, two positioning pins 321 and two elastic members 322 are provided, and are respectively provided on two supporting parts 312. Specifically, the positioning pin 321 extends vertically and is provided through the lower end of the supporting part 312, so that the positioning pin 321 can reciprocate vertically in the lower end of the supporting part 312. The elastic member 322 is provided as a vertically extending spring and is located in the supporting part 312. The elastic member 322 is coaxially sleeved on the positioning pin 321, and one end of the elastic member 322 is connected to the positioning pin 321, and the other end is connected to the supporting part 312.

[0067] The elastic member 322 can keep the positioning pin 321 moving downward, and then the lower end of the positioning pin 321 is inserted and matched with the positioning hole 121 through the push of the elastic member 322, so as to achieve the purpose of locking the limit member 310.

[0068] The control member 323 is provided as one and is disposed in the connecting portion 311 , so that the control member 323 can simultaneously pull the positioning pins 321 in the two supporting portions 312 to move the positioning pins 321 away from the positioning holes 121 , thereby achieving the purpose of unlocking the limiting member 310 .

[0069] In other embodiments, the elastic member 322 may also be configured as an elastic paddle fixed inside the support portion 312 , so that the elastic paddle can push the positioning pin 321 to move downward, thereby achieving the purpose of the positioning pin 321 being matched with the positioning hole 121 .

[0070] like Figure 4 and Figure 5As shown, in some embodiments, the control member 323 includes a control portion 3231 and a traction member 3232 , the control portion 3231 is slidably disposed on the connecting portion 311 , one end of the traction member 3232 is connected to the positioning pin 321 , and the other end is connected to the control portion 3231 .

[0071] Specifically, the control part 3231 is set as one and is a block structure. The control part 3231 is inserted and slidably connected to the connection part 311. The traction member 3232 is set as a traction rope, which can be made of plastic or a filamentary structure made of metal such as copper and iron, without limitation; the number of traction members 3232 corresponding to the positioning pins 321 is set to two, and the two traction members 3232 are respectively set to the two positioning pins 321. One end of the traction member 3232 is connected to the positioning pin 321, and the other end is connected to the control part 3231; the traction member 3232 can be connected to the positioning pin 321 or the control part 3231 by bonding, welding or binding, without limitation.

[0072] During operation, the pressing control part 3231 can simultaneously pull the two traction parts 3232, and then simultaneously pull the two positioning pins 321 away from the positioning hole 121, so as to achieve the purpose of unlocking the limit member 310; when the pressing on the control part 3231 is cancelled, the positioning pin 321 will automatically be plugged into and matched with the positioning hole 121 at the bottom of the sliding channel 120 under the push of the elastic part 322, so as to achieve the purpose of locking the limit member 310 and complete the position adjustment of the limit member 310.

[0073] In other embodiments, the control part 3231 can also be configured as a rotating rod or a rotating disk, in which case the rotating rod or the rotating disk is rotatably disposed on the connecting part 311, and the end of the traction member 3232 away from the positioning pin 321 is connected to the movable end of the rotating rod or the rotating disk. When the rotating rod or the rotating disk is rotated, the traction member 3232 can be pulled, thereby achieving the purpose of pulling the positioning pin 321.

[0074] like Figure 5 As shown, in some embodiments, the control member 323 also includes a reset member 3233 disposed on the connecting portion 311, and the reset member 3233 is configured such that when the elastic member 322 pushes the positioning pin 321 to move toward the positioning hole 121, the reset member 3233 pushes the control portion 3231 to move in the opposite direction, thereby reducing the resistance encountered by the positioning pin 321.

[0075] In the embodiment of the present application, the reset member 3233 is a spring and is arranged inside the connecting part 311. One end of the reset member 3233 supports the connecting part 311, and the other end is connected to the control part 3231, so that after the control part 3231 is pressed, the reset member 3233 has a reverse thrust on the control part 3231.

[0076] Specifically, the reset member 3233 is located in front of the control part 3231 in the pressing direction, and the axial direction of the reset member 3233 is parallel to the pressing direction of the control part 3231; at this time, the control part 3231 is integrally formed with a support column, and the support column is coaxially arranged on the inner side of the reset member 3233, so that the support column has a better supporting effect on the compression and reset process of the reset member 3233, thereby improving the stability of the reset member 3233 during use.

[0077] When the position of the limiter 310 is adjusted, the pressure on the control part 3231 is canceled, and when the elastic part 322 pushes the positioning pin 321 to slide toward the positioning hole 121, the reset part 3233 will simultaneously push the control part 3231 to reset. Therefore, in the process of the positioning pin 321 moving toward the positioning hole 121, the pulling force of the traction part 3232 that needs to be overcome can be reduced, so that the speed of the positioning pin 321 when resetting is higher, and the overall use effect of the locking part 320 is better.

[0078] In other embodiments, the reset member 3233 may also be configured as an elastic paddle, so that the elastic paddle is disposed on the inner side of the connecting portion 311 and is used to push the control portion 3231 to reset.

[0079] like Figure 3 and Figure 6 As shown, in some embodiments, a clamping block 600 is provided at one end of the limit member 310 away from the rail groove 110, and the clamping block 600 is configured so that after the limit member 310 is tilted and slides into the sliding channel 120 from the side of the base 100, the clamping block 600 cooperates with one end of the sliding channel 120 toward the side of the base 100 to at least partially fasten the limit member 310 in the sliding channel 120.

[0080] In the embodiment of the present application, the number of the clamping blocks 600 corresponding to the supporting parts 312 is set to two, and the two clamping blocks 600 are respectively fixed to the ends of the two supporting parts 312 away from the track groove 110, so that the clamping blocks 600 can cooperate with the open ends of the sliding channel 120 facing the side of the base 100. Specifically, the clamping blocks 600 are integrally formed with the supporting parts 312. Of course, the clamping blocks 600 can also be fixed to the supporting parts 312 by welding, bonding or screwing, which is not limited.

[0081] When the stopper 310 is stored, the stopper 310 is rotated as a whole and moved toward the side of the sliding channel 120 as a whole, so that the support portion 312 is gradually inserted into the sliding channel 120, thereby achieving the purpose of partially storing the stopper 310. In addition, after the support portion 312 is completely inserted into the sliding channel 120, the clamping block 600 at the end of the support portion 312 will cooperate with the opening of the sliding channel 120, thereby locking the stopper 310 as a whole, improving the stability of the stopper 310 when it is partially stored, and reducing the possibility of the stopper 310 detaching from the sliding channel 120.

[0082] In order to improve the convenience of the clamping block 600 when cooperating with the sliding channel 120 , the edge of the clamping block 600 facing one end of the sliding channel 120 may also be set as a chamfered structure to facilitate the clamping block 600 to be inserted into the sliding channel 120 .

[0083] like Figure 6 As shown, specifically, the inner wall of the sliding channel 120 at one end facing the side of the base 100 has a clamping protrusion, and after the clamping block 600 is inserted into the sliding channel 120 from the side of the base 100, the clamping block 600 is interference fit in the sliding channel 120 through the clamping protrusion.

[0084] In actual configuration, the clamping protrusion is integrally formed by the inner wall of the sliding channel 120, and can also be fixed to the inner wall of the sliding channel 120 by welding or bonding; and the clamping protrusion can be in the shape of a convex point or a long strip, without limitation. After the clamping block 600 is inserted into the sliding channel 120, the clamping protrusion will be tightly pressed against the side wall of the clamping block 600, achieving an interference fit of the clamping block 600 in the sliding channel 120, thereby ensuring the stability of the limiting member 310 after partial storage.

[0085] In summary, the present application provides a stapler, when paper documents are center-stitched, the position of the limiter 310 is adjusted according to the specifications of the paper documents (such as A3, A4, etc.) and with reference to the scale mark 500, and then the limiter 310 is locked in the current position by the locking member 320, so that there is a better distance between the limiter 310 and the pressing binding mechanism 400. Then, the paper document only needs to be placed between the base 100 and the movable plate 200, so that the side of the paper document leans against the limiter 310, and the pressing binding mechanism 400 can be directly pressed down to staple the staples on the paper document, so that the staples are in a better binding position on the paper document, and the staples are evenly distributed at the center of the paper document with reference to the scale mark 500, so that the force on the binding part of the paper document is more uniform, the binding effect is good, and the operation process is convenient. The same operation can be performed on multiple paper documents of the same batch, so that the binding effect of the multiple paper documents is relatively neat and the binding efficiency is high, which solves the technical problem of poor binding effect of paper documents in the prior art.
