Abstract
Description
Technical Field
[0001] The invention relates to an electric stapler. Background Art
[0002] Existing electric staplers, such as an electronically controlled stapler disclosed in Chinese patent document CN2369864Y, include a machine base, a motor, a gear speed change mechanism, an eccentric wheel device, a lever mechanism, a blade assembly, and a nail track assembly. A micro switch is installed at the paper feed of the machine base. The micro switch can control the rotation of the motor. The motor is connected to the gear speed change mechanism. The gear speed change mechanism drives the eccentric wheel device. The eccentric wheel device drives the blade assembly to move up and down to press out the staples in the nail track assembly. The document to be stapled touches the micro switch once, the motor rotates once, and a stapling process is completed.
[0003] Since electric staplers are prone to staple jams, when users remove the jammed staples themselves, the staples are stuck and difficult to pull out. If the staples are pulled out forcibly, the upper blade may be deformed or even the binding mechanism may be completely destroyed, making the electric stapler unusable. Therefore, improvements are needed. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies of the prior art and provide an electric stapler so as to conveniently solve the problem of staple jamming.
[0005] The technical solution adopted by the present invention to solve the above technical problems is: an electric stapler, which includes a base, a bracket seat, a driving mechanism, an eccentric connecting rod mechanism, a nail channel assembly, a blade assembly, and a controller. The controller drives the eccentric connecting rod mechanism through the driving mechanism to make the blade assembly bind the nail channel assembly. The invention is characterized in that: a button lock assembly and a pop-up mechanism are also provided. The button lock assembly includes a button, a button lock spring, and a fixing pin. A pressing portion is provided at one end of the button, and a hook portion is provided at the other end. A hook groove corresponding to the hook portion is provided at the tail end of the nail channel in the nail channel assembly. The hook portion hooks the hook groove in a normal state. One end of the button lock spring is limited by the inner side of the button, and the other end is limited by the tail end of the nail channel. A trigger portion is also provided at the hook end of the button. The pop-up mechanism includes a swinging member and a pop-up connecting rod. The swinging member can be rotatably fixed on the circumference of the side wheel of the driving mechanism. The pop-up connecting rod is arranged below the swinging piece and can move forward and backward on the base. A pushing part is arranged at the rear part of the pop-up connecting rod, and the pushing part cooperates with the button triggering part of the button lock assembly. When the pop-up connecting rod moves forward, the pushing part causes the button triggering part to rotate upward so that the hook part at the end of the triggering part disengages from the tail hook groove of the inner nail channel and releases the inner nail channel. A moving part cooperating with the swinging part is arranged at the front part of the pop-up connecting rod. During binding, the controller controls the side wheels of the driving mechanism to rotate clockwise through the motor, and the swinging piece is outside the moving part and is not restricted. During stapling, the controller causes the side wheels to rotate counterclockwise through the motor, and the swinging piece is inside the moving part and is restricted to the moving part by the limiting part at the rear thereof, so that the moving part and the pop-up connecting rod move forward together with the side wheels, and the pop-up connecting rod pushing part causes the button triggering part to rotate upward so that the hook part at the end of the triggering part disengages from the tail hook groove of the inner nail channel and releases the inner nail channel.
[0006] Preferably, a moving part cooperating with the swinging part is provided at the front part of the pop-up connecting rod, the front end of the swinging part can extend out of the circumference of the side wheel and be blocked by the moving part, the front part of the swinging part in the clockwise direction is provided with a front blocking part, and the rear part of the swinging part is provided with a rear blocking part, and the swinging part is limited by the front blocking part and the rear blocking part. When the side wheel rotates clockwise, the swinging part moves downward due to its own gravity, and its head rests on the outer side of the moving part and can avoid the moving part because the rear blocking part is far away, so normal nailing can be carried out; when the side wheel rotates counterclockwise, the swinging part moves downward due to its own gravity, and its head rests on the inner side of the moving part. During rotation, the front blocking part blocks the swinging part from moving backward, so that the swinging part presses against the moving part and drives the moving part to move to the right, and finally the pushing part at the front of the pop-up connecting rod moves to the right, so that the hook end of the button rotates upward, so that the end hook is separated from the tail hook groove of the inner nail channel, so that the nail stuck in the nail channel assembly can be smoothly removed.
[0007] Preferably, the front end of the swing member is tooth-shaped (swinging tooth), and the front end of the moving part is also provided with an inner inclined surface matching the tooth, so that the front end of the swing member can easily detach from the moving part when the side wheel rotates clockwise.
[0008] Preferably, the swing gear is rotatably fixed on the circumference of the side wheel by screws, and this fixing method is more convenient.
[0009] More specifically, the trigger portion is an oblique groove on the back of the button, and the pushing portion of the pop-up connecting rod is a protruding surface. The oblique groove cooperates with the protruding surface. When the trigger portion is not subjected to force, the oblique groove holds the protruding surface; when the pop-up connecting rod moves forward, the protruding surface moves and lifts up the oblique groove, and the button also overcomes the spring force and rotates upward, thereby causing the button hook portion to disengage from the tail hook groove of the inner nail channel.
[0010] Preferably, a restoring mechanism is further provided between the pop-up connecting rod and the base, and when the pop-up connecting rod pushes an external force, the restoring mechanism enables the pop-up connecting rod to return to its original position.
[0011] More specifically, the return mechanism is a return spring, the front end of which is limited by the end of a pop-up link, and the rear end of which is limited by a bracket on the base. A guide groove is also provided on the pop-up link, and a guide pin is inserted into the guide groove. The guide pin is fixed on the base. In this way, when the pop-up link is moved to the right by the swing tooth, the guide pin can guide and compress the return spring. When the pop-up link loses the external force of the swing tooth, the return force of the return spring resets the pop-up link.
[0012] Preferably, a limiting mechanism is arranged beside the swing tooth in the counterclockwise direction, and the limiting mechanism includes an elastic member, and the elastic member includes two bent pieces, one piece is fixed on the side wheel, and the other piece is beside the swing tooth. A protrusion spaced from the swing tooth is also arranged on the edge of the swing tooth, and the other piece of the elastic member is on the counterclockwise path of the protrusion. This can better ensure that the swing tooth can fall on the inner side of the pushing part when the side wheel rotates counterclockwise.
[0013] Preferably, the nail channel assembly includes an inner nail channel, an outer nail channel, a long pin pusher, a nail pusher, and a nail pusher spring. The inner nail channel is placed in the outer nail channel and can slide in the outer nail channel. A hook groove is provided at the tail of the inner nail channel. One end of the long pin pusher is fixed to the tail of the outer nail channel, and the other end is fixed to the front of the outer nail channel. The nail pusher spring is sleeved on the long pin pusher, one end of which is limited by the tail of the outer nail channel, and the other end is fixed to the nail pusher. The nail pusher is placed in the inner nail channel and can slide in the inner nail channel. The staples are placed between the head of the inner nail channel and the front end of the nail pusher, so that the nail channel assembly stapling and staple processing mechanisms are consistent.
[0014] Compared with the prior art, the present invention has the following advantages: due to the provision of a button lock assembly and a pop-up mechanism, the two cooperate with the existing nail channel assembly and the eccentric connecting rod mechanism, and when a nail is stuck, the driving mechanism can be reversely started to make the nail channel in the nail channel assembly pop out, so that the nail stuck in the nail channel assembly can be smoothly removed, thereby conveniently solving the problem of nail jamming.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] For the convenience of description, the directional words used below, such as front, back, clockwise, counterclockwise, etc., are described according to the existing drawings. They are not limitations on the protection scope of the present invention and can still change accordingly according to different visual directions of the drawings. Example
[0030] like Figure 1-12 As shown, the electric stapler includes a base 1, a bracket base 2, a motor 3, a transmission gear 75, a reduction gear set 7, a button lock assembly 4, an ejection mechanism 5, an eccentric connecting rod mechanism 6, a staple channel assembly 8, a blade assembly 9, and a controller (not shown in the figure).
[0031] The bracket seat 2 is fixed on the base 1, the motor 3 is fixed on the bracket seat 2 by screws, and the transmission gear 75 is fixed on the motor shaft.
[0032] A gear box 21 is also provided on the bracket seat 2. The reduction gear set 7 includes four reduction gears 71, 72, 73, and 74. Each reduction gear is fixed in the gear box 21 of the bracket seat 2 by a pin. The reduction gear 74 is meshed with the transmission gear 75.
[0033] An eccentric connecting rod mechanism 6 is arranged in the bracket seat 2, and the eccentric connecting rod mechanism 6 includes a connecting rod 61, a supporting pin 62, a guide shaft 63, and a side wheel 64. One end 611 of the connecting rod 61 is connected to the blade assembly 9, and the other end 612 is provided with a guide groove 613. The guide shaft 63 of the last gear 71 of the reduction gear group is connected to the guide groove 613 through a rubber ring 68. One end of the guide shaft 63 is fixed on the circumference of the last gear 71 of the reduction gear group, and the other end is fixed on the circumference 641 of the side wheel 64. The side wheel 64 is fixed on the other side of the bracket seat 2. The side wheel 64 The connecting rod 66 is fixed between the center of the circle of the last gear 71, and a supporting groove 612 is also provided at the front of the connecting rod 61. After the supporting pin 62 passes through the supporting groove 612, its two ends are fixed on the two sides of the bracket seat 2. When the last gear 71 rotates, the guide shaft 63 rotates eccentrically, and the connecting rod 61 moves up and down through the limiting guidance of the guide groove 613, thereby driving the blade assembly 9 to move up and down. As a result, the rotational movement on the last gear 71 of the reduction gear set 7 is transmitted through the eccentric connecting rod mechanism 6 to move the blade assembly 9 up and down, so that the staples in the nail channel assembly are ejected to complete the binding work.
[0034] In this embodiment, the two ends of the support pin 62 are fixed on the two sides of the bracket seat 2 through the fixed buffer ring 65, so that the support pin 62 can move to a certain extent to prevent damage caused by the rigid connection with the bracket seat 2.
[0035] The above-mentioned nail channel assembly 8 includes an inner nail channel 81, an outer nail channel 82, a long pin pusher 83, a nail pusher 84, and a nail pusher spring 85. The inner nail channel 81 is placed in the outer nail channel and can slide in the outer nail channel. A hook groove 811 is set at the tail of the inner nail channel 81. One end of the long pin pusher 83 is fixed to the tail of the outer nail channel, and the other end is fixed to the front of the outer nail channel. The nail pusher spring 85 is sleeved on the long pin pusher 83, one end of which is limited by the tail of the outer nail channel 82, and the other end is fixed on the nail pusher 84. The nail pusher 84 is placed in the inner nail channel and can slide in the inner nail channel. The staples are placed between the head of the inner nail channel and the front end of the nail pusher 84.
[0036] The staple channel assembly 8 is fixed to the base 1 through the outer staple channel 82 and cooperates with the blade assembly. The blade 91 in the blade assembly pushes out the staples installed in the inner staple channel 81 and staples.
[0037] A nail channel handle 816 is further provided at the other end of the inner nail channel 81 , and the inner nail channel 816 can be moved by the nail channel handle 86 .
[0038] A sensor switch 10 is also provided next to the staple channel assembly 8. When a sheet of paper enters during stapling, the sensor switch 10 can sense it and send a signal to the controller, which then starts the motor 3 for stapling.
[0039] The blade assembly 9 comprises a blade 91, a blade seat 94 and a fixing member 93. The blade 91 is fixed to the blade seat 94 by the fixing member 93. The blade seat 94 is provided with a connecting groove 941. One end 611 of the connecting rod 61 is inserted into the connecting groove 941 and is rotatably connected by a connecting pin 942.
[0040] The above-mentioned blade assembly 9 is arranged in the front end bracket cavity 23 of the bracket seat 2, and the blade assembly 9 is also provided with a guide 92. One end of the guide 92 is fixed in the side groove of the blade seat 94, and the other end is inserted into the blade guide groove 231 of the bracket seat 2. In this way, the blade assembly 9 can be driven to move up and down under the guidance of the guide 92 by one end 611 of the connecting rod 61, and the binding function is realized by the blade 91.
[0041] A trigger switch 15 is also provided next to the guide member 92. When the guide member 92 moves downward, the trigger switch 15 is triggered, and the trigger switch gives a signal to the controller. The controller continues to move the blade assembly 9 downward through the motor 3 and the eccentric connecting rod mechanism 6 to complete the stapling.
[0042] The pop-up mechanism 5 includes a swing tooth 51 and a pop-up connecting rod 52. The swing tooth 51 is rotatably fixed on the circumference of the side wheel 64 by screws. The pop-up connecting rod 52 is arranged below the swing tooth 51, movably connected to the base 1, and can move back and forth on the base 1.
[0043] A pushing portion 521 is provided at the rear of the pop-up link 52, and the pushing portion 521 cooperates with one end of the button 41 of the button lock assembly 4. When the pop-up link 52 moves to the right, the pushing portion 521 causes one end of the button 41 to rotate upward so that the end hook portion 412 disengages from the tail hook groove 811 of the inner nail channel 81.
[0044] The front part of the pop-up connecting rod 52 is provided with a moving part 522 cooperating with the swing tooth 51. The front end of the swing tooth 51 can extend out of the circumference of the side wheel 64 and be blocked by the moving part 522. The front part of the swing tooth 51 has a front blocking part 642 in the clockwise direction and a rear blocking part 643 in the rear. The swing tooth 51 is limited by the front blocking part 642 and the rear blocking part 643. When the side wheel 64 rotates clockwise, the swing tooth 51 moves downward due to its own gravity, and its tooth tip leans against the outer side of the moving part 522. The swing tooth 51 can avoid the moving part 522 because the rear blocking part 643 is far away. Fig.11 When the side wheel 64 rotates counterclockwise, the swing tooth 51 moves downward due to its own gravity, and its tooth tip leans against the inner side of the moving part 522. When rotating, the front blocking part 642 blocks the swing tooth 51 from moving backward, so that the swing tooth 51 abuts against the moving part 522, and drives the moving part 522 to move forward, and finally the pushing part 521 at the front of the pop-up connecting rod 52 moves forward, so that one end of the button 41 rotates upward, so that the end hook part 412 is separated from the tail hook groove 811 of the inner nail channel 81, so that the inner nail channel 81 is ejected under the action of the nail pusher spring 85, so that the paper stuck in the nail channel assembly can be smoothly taken out. Fig.12 .
[0045] A restoring mechanism is further provided between the pop-up link 52 and the base 1. In the present embodiment, the restoring mechanism is a restoring spring 53. The front end of the restoring spring 53 is limited by the end of the pop-up link 52, and the rear end of the restoring spring 53 is limited by the bracket 13 on the base 1. A guide groove 523 is further provided on the pop-up link 52. A guide pin 54 is inserted into the guide groove 523. The guide pin 54 is fixed on the base 1 (not shown in the figure). In this way, when the pop-up link 52 is moved to the right by the swing tooth 51, the guide pin 54 can guide and compress the restoring spring 53. When the pop-up link 52 loses the external force of the swing tooth 51, the restoring force of the restoring spring 53 resets the pop-up link 52.
[0046] The button lock assembly 4 comprises a button 41, a button lock spring 42 and a fixing pin 43. A pressing portion 411 is provided at one end of the button 41 and a hook portion 412 is provided at the other end. The hook portion 412 hooks the tail hook groove 811 of the inner nail channel 81 in a normal state. One end of the button lock spring 42 is limited by the inner side of the button 41 and the other end is limited by the tail end 821 of the nail channel.
[0047] The button 41 is also provided with a trigger portion 414. The trigger portion of the present embodiment is provided on the side of the button 41, and an oblique groove 4141 is provided on the back thereof. The oblique groove 4141 cooperates with a protruding surface 521 provided on one end of the pop-up connecting rod 52 on the pop-up mechanism 5. When the trigger portion 414 is not subjected to force, the oblique groove 4141 holds the protruding surface 521 at one end of the pop-up connecting rod. When one end of the pop-up connecting rod moves outward, the protruding surface 521 moves and lifts up the oblique groove 4141, and the button 41 also overcomes the spring force and rotates outward, thereby causing the hook portion 412 of the button 41 to disengage from the tail hook groove of the inner nail channel 81.
[0048] The binding process of the above electric stapler is as follows:
[0049] When the paper is inserted into the nail track and contacts the contact switch 10, the contact switch 10 sends a signal to the controller, and the controller sends a signal to start the motor 3, driving the transmission gear 75 to rotate. The transmission gear 75 is decelerated by the reduction gear group and then drives the connecting rod assembly 6 to rotate. The connecting rod assembly 6 drives the blade assembly 9 to move downward through its one end 611. The guide rod 92 triggers the quick-action switch 74 to make the motor 3 continue to rotate clockwise. At this time, the connecting rod assembly 6 continues to drive the blade assembly 9 to move downward, pushing out the staples in the nail track assembly, bending the staples into shape at the nail plate 14, and completing a circle of stapling. At this time, the side wheel 64 rotates clockwise, and the swinging tooth 9 on the side wheel 64 contacts the ejection connecting rod (the swinging tooth avoids air), which does not affect normal binding. Fig.11 .
[0050] The above-mentioned normal stapling is similar to the action of the electric stapler disclosed in Chinese patent document CN2369864Y, and reference may also be made to the description in the above document.
[0051] When the electric stapler is stuck, the controller controls the motor 3 to reverse, so that the side wheel 64 reverses counterclockwise to drive the lever to lift the blade assembly 9, and the swing tooth 51 on the side wheel 64 falls on the inner side of the pushing portion and is restricted by the pushing portion and the front blocking portion 642, thereby driving the ejection link 52 to move forward, and finally the pushing portion 521 at the front of the ejection link 52 moves forward and one end of the button 41 rotates upward to make the end hook portion 412 disengage from the tail hook groove 811 of the inner nail channel 81, so that the inner nail channel 81 is ejected under the action of the nail pusher spring 85, so that the paper stuck in the nail channel assembly can be smoothly removed. Fig.12 .
[0052] Another embodiment
[0053] This embodiment is the same as the previous embodiment except for the following differences.
[0054] In the above-mentioned embodiment, a limiting mechanism is arranged beside the swing tooth 51 in the counterclockwise direction, and the limiting mechanism includes an elastic member 516. The elastic member 516 includes two bent pieces 5161 and 5162. The piece 5161 is fixed on the side wheel 64, and the other piece 5162 is beside the swing tooth 51. A protrusion 511 spaced apart from the swing tooth 51 is also arranged on the edge of the swing tooth 51. The other piece 5162 of the elastic member 516 is on the counterclockwise path of the protrusion 511. In this way, when the side wheel 64 is rotating, if the swing tooth 51 rotates counterclockwise, the other piece 5162 of the elastic member 516 will limit the swing tooth 51 and prevent it from deviating, thereby ensuring that the swing tooth can fall on the inner side of the pushing portion when the side wheel rotates counterclockwise, thereby smoothly realizing its function of pushing the pop-up connecting rod forward counterclockwise.
