Description

Technical Field

[0001] The present invention relates to the technical field of office equipment, and particularly to a punching and riveting device and a binding machine. Background Art

[0002] A binding machine is a binding device that mechanically (manually, automatically or fully automatically) fixes materials such as paper, bills, plastics or leather with binding nails, hot melt adhesives or nylon tubes, etc. According to different uses, it can be divided into industrial binding machines and civilian binding machines, and is commonly used in financial offices or file management in printing factories, enterprises and institutions, etc.

[0003] Taking nylon tube materials as an example for illustration, a binding machine generally includes a frame and a workbench, a pressing mechanism, a cutting mechanism and a punching and riveting mechanism that are all connected to the frame. The pressing mechanism can move up and down relative to the frame, the cutting mechanism can cut the nylon tube into small sections for binding use, the punching and riveting mechanism includes a drill bit assembly and a riveting assembly. The drill bit assembly can drill holes in the material to be bound, and the riveting assembly can insert the cut nylon tube into the above-mentioned drilled holes.

[0004] During operation, the material to be bound is placed on the workbench and pressed against the workbench by the pressing mechanism. The cutting mechanism cuts the nylon tube into small sections and collects them in the riveting assembly. The drill bit assembly drills holes in the material to be bound, and then the riveting assembly inserts the cut nylon tube into the drilled holes to complete the binding of the material.

[0005] Among them, the punching and riveting mechanism is preset with two rotation limit positions. The first rotation limit position is that the drill bit assembly is in the working position. At this time, the drill bit assembly corresponds to the material to be bound to drill holes at the corresponding position of the material to be bound. The second rotation limit position is that the riveting assembly is in the working position. At this time, the riveting assembly corresponds to the material to be bound to insert the nylon tube into the drilled hole. Therefore, the punching and riveting mechanism needs to rotate to switch the working position. For example, the normal position of the punching and riveting mechanism is the first rotation limit position. Normally, the drill bit assembly corresponds to the material to be bound. When riveting is required, the punching and riveting mechanism rotates so that the punching and riveting mechanism is in the second rotation limit position, making the riveting assembly correspond to the material to be bound. However, in the prior art, the rotation of the punching and riveting mechanism from the first rotation limit position to the second rotation limit position often fails to reach the position, affecting the normal use of the binding machine.

[0006] Therefore, the present application provides a new punching and riveting device and a binding machine for the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a punching and riveting device to solve the technical problem that the rotation of the punching and riveting mechanism of the binding machine in the prior art fails to reach the position.

[0008] The object of the present invention is further to provide a binding machine to further solve the technical problem that the rotation of the punching and riveting mechanism of the binding machine in the prior art is not in place.

[0009] Based on the above first object, the present invention provides a punching and riveting device, including a frame, a punching and riveting mechanism, and a pull rod capable of lifting relative to the frame;

[0010] The punching and riveting mechanism includes a rotating seat capable of rotating relative to the frame, and a drill bit assembly and a riveting assembly both connected to the rotating seat. The drill bit assembly can drill the material to be bound, and the riveting assembly can insert a nylon tube into the drilled hole;

[0011] A rotation receiving member is arranged on the rotating seat, and a rotation driving member is arranged on the pull rod. One end of the rotation driving member is rotatably connected to the pull rod, and the other end is connected to the pull rod through an elastic member;

[0012] The rotating seat is preset with a first rotation limit position and a second rotation limit position. When the rotating seat is in the first rotation limit position, the drill bit assembly is in the working position; when the rotating seat is in the second rotation limit position, the riveting assembly is in the working position;

[0013] During the process of the pull rod rising relative to the frame, the rotation driving member can contact the rotation receiving member and drive the rotation receiving member to move, so that the rotation receiving member drives the rotating seat to rotate from the first rotation limit position to the second rotation limit position;

[0014] Wherein, during the movement of the rotation receiving member, the rotation receiving member can make one end of the rotation driving member rotate relative to the pull rod, and the other end can overcome the pre-tightening force of the elastic member to compress the elastic member.

[0015] Further, the rotation driving member includes a first end and a second end arranged oppositely;

[0016] A receiving hole is formed on the circumferential surface of the pull rod. The first end is arranged in the receiving hole and is rotatably connected to the pull rod through a first threaded connector, and the second end is connected to the pull rod through an elastic member.

[0017] Further, the receiving hole is a long hole extending along the length direction of the pull rod;

[0018] When the rotation driving member rotates relative to the first threaded connector to compress the elastic member, a part of the rotation driving member can enter the receiving hole.

[0019] Further, the punching and riveting device further includes a second threaded connector, and the elastic member is a helical spring;

[0020] A through hole is formed in the pull rod, a threaded hole is formed in the second end, the second threaded connecting piece passes through the through hole and is screwed into the threaded hole, and the nut of the second threaded connecting piece abuts against the pull rod. The helical spring is sleeved outside the second threaded connecting piece;

[0021] When the helical spring is compressed, the second end can drive the second threaded connecting piece to move along the through hole.

[0022] Further, the drill bit assembly includes a first slider capable of lifting relative to the rotating seat and a drill sleeve rotatably connected to the first slider, and a drill bit is arranged in the drill sleeve;

[0023] The riveting press-fitting assembly includes a second slider capable of lifting relative to the rotating seat and a guide pin arranged on the second slider.

[0024] Further, the punching and riveting mechanism further includes a rotating assembly capable of driving the drill sleeve to rotate relative to the first slider.

[0025] Further, the punching and riveting mechanism further includes a lifting assembly installed on the frame, a driving pin is arranged on the lifting assembly, and the lifting assembly can drive the driving pin to lift relative to the frame;

[0026] The first slider is provided with a first card slot, the second slider is provided with a second card slot. When the drill bit assembly is in the working position, the driving pin is clamped in the first card slot, and the driving pin can drive the first slider to lift; when the riveting press-fitting assembly is in the working position, the driving pin is clamped in the second card slot, and the driving pin can drive the second slider to lift.

[0027] Adopting the above technical solution, the punching and riveting device of the present invention has the following beneficial effects:

[0028] When the punching and riveting device works, the drill bit assembly drills the material to be bound, and the nylon tube is inserted into the drilled hole through the riveting press-fitting assembly to complete the binding operation. Among them, the punching and riveting device rotates by the relative rotation of the rotating seat and the frame to realize the switching of the two rotation limit positions of the rotating seat.

[0029] It should be noted that the rotation limit position is the limit position that the rotating seat can reach by rotation. That is, the rotating seat can only rotate between the first rotation limit position and the second rotation limit position. When the rotating seat rotates from the first rotation limit position to the second rotation limit position, the rotating seat cannot continue to rotate and stops. When the rotating seat rotates from the second rotation limit position to the first rotation limit position, the rotating seat cannot continue to rotate and stops.

[0030] Specifically, the pull rod rises relative to the frame, so that the pull rod drives the indexing drive member to rise, so that the indexing drive member can contact the indexing receiving member and drive the indexing receiving member to move, so that the indexing receiving member drives the rotating seat to rotate relative to the frame.

[0031] Wherein, during the process of the indexing drive member rising, the indexing drive member contacts the indexing receiving member, and the indexing receiving member reacts on the indexing drive member, applying pressure to the indexing drive member, so that one end of the indexing drive member rotates relative to the pull rod, and the other end overcomes the pre-tightening force of the elastic member to compress the elastic member.

[0032] If the rotating seat does not rotate in place, that is, the rotating seat has not reached the second rotation limit position, during the process of the pull rod rising relative to the frame, the indexing drive member continues to contact the indexing receiving member and drive the indexing receiving member to move, so that the rotating seat continues to rotate; if the rotating seat rotates in place, that is, the rotating seat rotates to the second rotation limit position, the rotating seat will not continue to rotate, so the indexing receiving member will not continue to rotate. At this time, during the process of the pull rod rising relative to the frame, the indexing receiving member makes one end of the indexing drive member continue to rotate relative to the pull rod, and the other end continues to overcome the pre-tightening force of the elastic member to compress the elastic member, so as to make the indexing drive member rotate relative to the pull rod to be closer to the pull rod through the compression of the elastic member, providing a clearance space for the indexing receiving member, so that the indexing drive member and the indexing receiving member will not be damaged due to interference. Therefore, when the pull rod rises relative to the frame, it will not affect the indexing receiving member, that is, even if the rotating seat rotates to the second rotation limit position, the pull rod can still continue to rise.

[0033] Therefore, as long as the pull rod rises relative to the frame, the rotating seat can keep rotating until the rotating seat rotates to the second rotation limit position and stops rotating. During the process of the pull rod continuing to rise, the indexing drive member and the indexing receiving member will not affect each other. Therefore, the punching and riveting device can ensure that the rotating seat rotates from the first rotation limit position to the second rotation limit position, that is, it can ensure that the punching and riveting device rotates in place.

[0034] In summary, the punching and riveting device can make the rotating seat rotate by the rising of the pull rod. If the rotating seat does not rotate in place, the pull rod continues to rise until the punching and riveting device rotates in place and stops rotating. If the punching and riveting device rotates in place, the continued rising of the pull rod will not affect the punching and riveting device. Therefore, the punching and riveting device alleviates the technical problem of the incomplete rotation of the punching and riveting mechanism of the binding machine in the prior art.

[0035] Based on the above second object, the present invention provides a binding machine, including the punching and riveting device described above.

[0036] Further, the binding machine further includes a material cutting mechanism;

[0037] The blanking mechanism includes a blanking pipe, a toggling member, and a sliding seat connected to the frame. A slideway is provided on the sliding seat, and a sliding plate capable of sliding along the slideway is provided on the slideway. A cutting knife is provided on the sliding plate. One end of the toggling member is disposed in the slideway and abuts against the sliding plate. The blanking pipe corresponds to the cutting knife.

[0038] A rotating body is provided on the pull rod. The toggling member is provided with an inclined surface. During the process of the pull rod rising relative to the frame, the circumferential surface of the rotating body can contact the inclined surface and cause the inclined surface to move relative to the rotating body, so that the toggling member moves, and thus the toggling member pushes the sliding plate to slide along the slideway, and thus the cutting knife slides to cut the blanking in the blanking pipe.

[0039] Further, the binding machine further includes a pressing mechanism;

[0040] The pressing mechanism includes an upper pressing arm and a lower pressing arm both connected to the frame and capable of lifting relative to the frame. The upper pressing arm is disposed at the upper end of the lower pressing arm. The pull rod is connected to the upper pressing arm.

[0041] Adopting the above technical solution, the binding machine of the present invention has the following beneficial effects:

[0042] By providing the above punching and riveting device in the binding machine, correspondingly, the binding machine has all the advantages of the above punching and riveting device, which will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Embodiment 1

[0068] Please refer to Figure 2 and Figure 3 , this embodiment provides a punching and riveting device. The punching and riveting device includes a frame 11, a punching and riveting mechanism, and a pull rod 2 that can move up and down relative to the frame 11; please continue to refer to Figure 4 , the punching and riveting mechanism includes a rotating seat 31 that can rotate relative to the frame 11, and a drill bit assembly 4 and a riveting assembly 5 both connected to the rotating seat 31. The drill bit assembly 4 can drill holes in the material to be bound, and the riveting assembly 5 can insert a nylon tube into the drilled hole. A rotation receiving member 32 is provided on the rotating seat 31, and a rotation driving member 22 is provided on the pull rod 2. One end of the rotation driving member 22 is rotatably connected to the pull rod 2, and the other end is connected to the pull rod 2 through an elastic member 23.

[0069] The rotating seat 31 is preset with a first rotation limit position and a second rotation limit position. When the rotating seat 31 is in the first rotation limit position, the drill bit assembly 4 is in the working position; when the rotating seat 31 is in the second rotation limit position, the riveting assembly 5 is in the working position.

[0070] During the process of the pull rod 2 rising relative to the frame 11, the indexing drive member 22 can contact the indexing receiving member 32 and drive the indexing receiving member 32 to move, so that the indexing receiving member 32 drives the rotating seat 31 to rotate from the first rotation limit position to the second rotation limit position; wherein, during the movement of the indexing receiving member 32, the indexing receiving member 32 can make one end of the indexing drive member 22 rotate relative to the pull rod 2, and the other end can overcome the pre-tightening force of the elastic member 23 to compress the elastic member 23.

[0071] With such a setting, when the punching and riveting device works, the drill bit assembly 4 drills the material to be bound, and the riveting assembly 5 inserts the nylon tube into the drilled hole to complete the binding operation. Among them, the rotation of the rotating seat 31 relative to the frame 11 realizes the rotation of the punching and riveting device, so as to realize the switching between the two rotation limit positions of the rotating seat 31.

[0072] It should be noted that the rotation limit position is the limit position that the rotating seat 31 can reach by rotation, that is, the rotating seat 31 can only rotate between the first rotation limit position and the second rotation limit position. When the rotating seat 31 rotates from the first rotation limit position to the second rotation limit position, the rotating seat 31 cannot continue to rotate and stops. When the rotating seat 31 rotates from the second rotation limit position to the first rotation limit position, the rotating seat 31 cannot continue to rotate and stops.

[0073] Specifically, by raising the pull rod 2 relative to the frame 11, the pull rod 2 drives the indexing drive member 22 to rise, so that the indexing drive member 22 can contact the indexing receiving member 32 and drive the indexing receiving member 32 to move, so that the indexing receiving member 32 drives the rotating seat 31 to rotate relative to the frame 11.

[0074] Among them, during the process of the indexing drive member 22 rising, the indexing drive member 22 contacts the indexing receiving member 32, and the indexing receiving member 32 reacts on the indexing drive member 22, applying pressure to the indexing drive member 22, so that one end of the indexing drive member 22 rotates relative to the pull rod 2, and the other end overcomes the pre-tightening force of the elastic member 23 to compress the elastic member 23.

[0075] If the rotating seat 31 does not rotate to the proper position, that is, the rotating seat 31 has not reached the second rotation limit position, during the process of the pull rod 2 rising relative to the frame 11, the indexing drive member 22 continues to contact the indexing receiving member 32 and drive the indexing receiving member 32 to move, so that the rotating seat 31 continues to rotate; if the rotating seat 31 rotates to the proper position, that is, the rotating seat 31 rotates to the second rotation limit position, the rotating seat 31 will not continue to rotate. Therefore, the indexing receiving member 32 will not continue to rotate. At this time, during the process of the pull rod 2 rising relative to the frame 11, the indexing receiving member 32 causes one end of the indexing drive member 22 to continue to rotate relative to the pull rod 2, and the other end continues to overcome the pre-tightening force of the elastic member 23 to compress the elastic member 23. Thus, by compressing the elastic member 23, the indexing drive member 22 rotates relative to the pull rod 2 to be closer to the pull rod 2, providing a clearance space for the indexing receiving member 32. Therefore, the indexing drive member 22 and the indexing receiving member 32 will not be damaged due to interference. Therefore, when the pull rod 2 rises relative to the frame 11, it will not affect the indexing receiving member 32, that is, even if the rotating seat 31 rotates to the second rotation limit position, the pull rod 2 can still continue to rise.

[0076] Therefore, as long as the pull rod 2 rises relative to the frame 11, the rotating seat 31 can keep rotating until the rotating seat 31 rotates to the second rotation limit position and stops rotating. During the process of the pull rod 2 continuing to rise, the indexing drive member 22 and the indexing receiving member 32 will not affect each other. Therefore, this punching and riveting device can ensure that the rotating seat 31 rotates from the first rotation limit position to the second rotation limit position, that is, it can ensure that the punching and riveting device rotates to the proper position.

[0077] In summary, this punching and riveting device can make the rotating seat 31 rotate by the rising of the pull rod 2. If the rotating seat 31 does not rotate to the proper position, the pull rod 2 continues to rise until the punching and riveting device rotates to the proper position and stops rotating. If the punching and riveting device rotates to the proper position, the continued rising of the pull rod 2 will not affect the punching and riveting device. Therefore, this punching and riveting device alleviates the technical problem of the incomplete rotation of the punching and riveting mechanism of the binding machine existing in the prior art.

[0078] Optionally, a first limiting structure and a second limiting structure are provided on the frame 11. The first limiting structure is used to limit the first rotation limit position of the rotating seat 31, and the second limiting structure is used to limit the second rotation limit position of the rotating seat 31. That is to say, when the rotating seat 31 rotates from the first rotation limit position to the second rotation limit position, the rotating seat 31 contacts the second limiting structure, and the limiting effect of the second limiting structure makes the rotating seat 31 unable to continue rotating and stop. When the rotating seat 31 rotates from the second rotation limit position to the first rotation limit position, the rotating seat 31 contacts the first limiting structure, and the limiting effect of the first limiting structure makes the rotating seat 31 unable to continue rotating and stop. Optionally, both the first limiting structure and the second limiting structure are screws connected to the frame 11.

[0079] Optionally, the rotation seat 31 is rotated back from the second rotation limit position to the first rotation limit position by a return spring (not marked in the figure) connected to the rotation seat 31 and the frame 11.

[0080] Optionally, the elastic member 23 is a spring or a spring piece, etc.

[0081] Preferably, please refer to Figure 9 and Figure 10 , in this embodiment, the indexing drive member 22 includes a first end and a second end disposed opposite to each other; a receiving hole 21 is formed on the circumferential surface of the pull rod 2, the first end is disposed in the receiving hole 21 and is rotatably connected to the pull rod 2 through a first threaded connector 24, and the second end is connected to the pull rod 2 through an elastic member 23.

[0082] With such a setting, the indexing drive member 22 is connected to the inside of the pull rod 2, thereby saving space and preventing the indexing drive member 22 from interfering with other components in the binding machine to a certain extent, so that the operation of the punching and riveting mechanism is more stable.

[0083] Preferably, please refer to Figure 10 , in this embodiment, the receiving hole 21 is a long hole extending along the length direction of the pull rod 2; when the indexing drive member 22 rotates relative to the first threaded connector 24 to compress the elastic member 23, a part of the indexing drive member 22 can enter the receiving hole 21.

[0084] With such a setting, on the one hand, it saves the internal space of the binding machine, and on the other hand, the receiving hole 21 provides a limiting function for the rotation of the indexing drive member 22, making the rotation of the indexing drive member 22 more stable and reducing the noise to a certain extent.

[0085] Preferably, please refer to Figure 10 , in this embodiment, the punching and riveting device further includes a second threaded connector 25, and the elastic member 23 is a helical spring; a through hole is formed on the pull rod 2, a threaded hole is formed at the second end, the second threaded connector 25 passes through the through hole and is screwed into the threaded hole, and the nut of the second threaded connector 25 abuts against the pull rod 2; the helical spring is sleeved outside the second threaded connector 25; when the helical spring is compressed, the second end can drive the second threaded connector 25 to move along the through hole.

[0086] With such a setting, when the second end overcomes the pre-tightening force of the helical spring to compress the helical spring, the second end drives the second threaded connector 25 to move relative to the pull rod 2 along the through hole, that is, the second threaded connector 25 is in clearance fit with the through hole.

[0087] In summary, the movement of the second threaded connector 25 along the through hole provides a guiding function for the movement of the second end of the indexing drive member 22, making the rotation of the indexing drive member 22 more stable and further reducing the operating noise.

[0088] Preferably, please refer toFigure 5 and Figure 6 In this embodiment, the drill bit assembly 4 includes a first slider 41 capable of lifting relative to the rotating seat 31 and a drill sleeve 42 rotatably connected to the first slider 41. A drill bit 43 is disposed inside the drill sleeve 42; the riveting press assembly 5 includes a second slider 51 capable of lifting relative to the rotating seat 31 and a guide pin 52 disposed on the second slider 51.

[0089] It should be noted that when the drill bit assembly 4 is in the working position, the drill sleeve 42 rotates relative to the first slider 41, enabling the drill bit 43 to rotate. Moreover, the first slider 41 rises relative to the rotating seat 31, capable of drilling the material to be bound.

[0090] The guide pin 52 is provided with a cut nylon tube. When the riveting press assembly 5 is in the working position, the guide pin 52 corresponds to the drilled hole. Thus, the second slider 51 rises relative to the rotating seat 31, causing the guide pin 52 to rise and insert the nylon tube into the drilled hole.

[0091] Preferably, in this embodiment, the punching and riveting mechanism further includes a rotating assembly capable of driving the drill sleeve 42 to rotate relative to the first slider 41.

[0092] Optionally, in this embodiment, the rotating assembly includes a rotating motor 61. A first belt pulley is fixedly connected to the output shaft of the rotating motor 61, and a second belt pulley is fixedly connected to the drill sleeve 42. The first belt pulley and the second belt pulley are connected by a conveyor belt. With such a setting, when the rotating motor 61 is started, it can drive the drill sleeve 42 to rotate through the first belt pulley, the conveyor belt, and the second belt pulley, thereby causing the drill bit 43 to rotate for drilling the material to be bound.

[0093] Preferably, in this embodiment, the rotating motor 61 is installed on the frame 11, and the rotating seat 31 is connected to the output shaft of the rotating motor 61 through a bearing. Therefore, the rotation of the output shaft of the rotating motor 61 does not affect the rotation of the rotating seat 31, and the output shaft of the rotating motor 61 provides a rotation center for the rotation of the rotating seat 31.

[0097] Embodiment 2

[0098] Embodiment 2 provides a binding machine, the binding machine includes the punching and riveting device of embodiment 1, the technical features of the punching and riveting device disclosed in embodiment 1 are also applicable to this embodiment, and the technical features of the punching and riveting device disclosed in embodiment 1 are not described again. The following is a further detailed description of the implementation of the binding machine in conjunction with the accompanying drawings.

[0099] See also Figure 1 The binding machine provided in this embodiment includes the punching and riveting device. The punching and riveting device further alleviates the technical problem of the punching and riveting mechanism of the binding machine not rotating properly in the prior art.

[0100] Preferably, see Figure 3 , Figure 8 and Figure 9 In this embodiment, the binding machine also includes a cutting mechanism 8; the cutting mechanism 8 includes a blanking tube, a toggle member 81 and a slide seat 82 connected to the frame 11, a slideway 83 is provided on the slide seat 82, a slideway 83 is provided on the slideway 83, a slide plate 84 that can slide along the slideway 83 is provided on the slideway 83, a cutter 85 is provided on the slide plate 84, one end of the toggle member 81 is provided in the slideway 83 and abuts against the slide plate 84, and the blanking tube corresponds to the cutter 85.

[0101] A rotating body 26 is provided on the pull rod 2, and a toggle member 81 is provided with an inclined surface 811. When the pull rod 2 rises relative to the frame 11, the circumferential surface of the rotating body 26 can contact the inclined surface 811, and the inclined surface 811 moves relative to the rotating body 26, so that the toggle member 81 moves, so that the toggle member 81 pushes the slide plate 84 to slide along the slideway 83, so that the cutter 85 slides to cut off the blanking in the blanking tube.

[0102] That is, the pull rod 2 rises relative to the frame 11 so that the cutting mechanism 8 cuts off the nylon tube in the blanking pipe.

[0103] With such an arrangement, the rising of the pull rod 2 relative to the frame 11 can drive the punching and riveting mechanism to rotate, and can also drive the cutting mechanism 8 to move, making the structure of the binding machine simpler and reducing the cost of the binding machine.

[0104] Preferably, seeFigure 2 In this embodiment, the binding machine also includes a clamping mechanism; the clamping mechanism includes an upper pressing arm 91 and a lower pressing arm 92 both connected to the frame 11 and capable of being raised and lowered relative to the frame 11, the upper pressing arm 91 is arranged at the upper end of the lower pressing arm 92, and the pull rod 2 is connected to the upper pressing arm 91.

[0105] It should be noted that the upper pressing arm 91 and the lower pressing arm 92 are lowered to press the materials to be bound. Specifically, the upper pressing arm 91 can drive the lower pressing arm 92 to descend together with the frame 11, so that the lower pressing arm 92 presses the materials to be bound, and the upper pressing arm 91 drives the pull rod 2 to descend.

[0106] On the basis that the lower pressure arm 92 always presses the material to be bound, the upper pressure arm 91 rises, thereby the pull rod 2 rises. On the one hand, during the process of the pull rod 2 rising relative to the frame 11, the transfer drive member 22 can contact the transfer receiving member 32 and drive the transfer receiving member 32 to move, so that the transfer receiving member 32 drives the rotating seat 31 to rotate from the first rotation limit position to the second rotation limit position; on the other hand, during the process of the pull rod 2 rising relative to the frame 11, the circumferential surface of the rotating body 26 can contact the inclined surface 811 and move the inclined surface 811 relative to the rotating body 26, so that the toggle member 81 moves, so that the toggle member 81 pushes the slide plate 84 to slide along the slideway 83, so that the cutter 85 slides to cut off the blanking in the blanking tube.

[0107] With this arrangement, the upper pressure arm 91 is lifted and lowered relative to the frame 11 to achieve the lifting and lowering of the pull rod 2, thereby driving the punching and riveting mechanism and the cutting mechanism 8 to move. In other words, the binding machine is a linkage binding machine, which makes the binding machine simple to install and maintain, and the operation of the binding machine is safer and more reliable.

[0108] Preferably, see Figure 1 In this embodiment, the binding machine also includes a shell 12, and the punching and riveting device, the cutting mechanism 8 and the pressing mechanism are all arranged in the shell 12.

[0109] The binding machine of this embodiment has the advantages of the punching and riveting device of the first embodiment, which have been described in detail in the first embodiment and will not be repeated here.
