Description

Technical Field

[0001] The invention relates to the field of coil binding devices, in particular to a binding machine. Background Art

[0002] In the traditional binding method, the coil is first inserted into the binding hole of each medium (e.g., paper, photo, etc.), and then the coil is manually pressed into a closed shape. However, this binding method is not only inefficient, but also has the problem that the coil cannot be completely pressed into a closed shape, and the medium may fall out of the coil during use.

[0003] To this end, the Chinese utility model patent with patent number ZL202121180841.7 (authorization announcement number CN217347268U) discloses a binding machine, including a bracket, the bracket is provided with a guide block for fixing the coil, a clamping assembly for clamping the coil, and a pressing assembly for pressing down the coil, the clamping assembly is located above the guide block, the pressing assembly includes a pressure rod, a buckle plate and a connecting plate, the pressure rod passes through the coil along the entire coil axis, one end of the pressure rod is fixed to the connecting plate, and the other end is close to the buckle plate, the buckle plate can be movably fixed to the connecting plate, and the connecting plate can be movably fixed to the bracket. Compared with the traditional binding method, the above patent improves the convenience of binding and improves the efficiency of binding, but the binding machine can only be used to bind coils of fixed size.

[0004] In addition, in order to achieve the binding of the medium, it is first necessary to punch holes in the medium, and after the holes are punched in the medium, the medium is bound together using a coil. In order to achieve both the punching and binding functions, a puncher and a binder need to be configured at the same time. However, configuring a puncher and a binder at the same time is not only costly, but also cumbersome to operate, affecting the user experience.

[0005] To this end, the Chinese utility model patent with patent number ZL99204863.X (authorization announcement number CN2362670Y) discloses a combined device for paper punching and binding, including a housing, a punching device, an elastic load pressure plate, a coil pressing device and an adjustable cam brake. The punching device is provided with a knife seat and a plurality of punching tools. Each tool is provided with a sliding baffle, which can choose whether to punch with the knife seat. The elastic load pressure plate is pivoted on the front end support shaft of the housing to assist the stacked paper to pass through the spiral coil. A second crank handle is fixed at the end of the second rotating shaft of the coil pressing device, and a transmission gear is provided to engage with the second tooth row of the L-shaped pressure plate to clamp the open spiral coil into a closed state. The adjustable cam brake is in contact with the protrusion of the L-shaped pressure plate. It can be seen that although the above patent assembles the punching function and the binding function on the same device, the structure is complicated, and the punching function and the binding function are simply combined together. The two are independent in structure and function, and the operation is still relatively troublesome. For example, the user is required to operate the first crank handle when punching, and the user is required to operate the second crank handle when pressing. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a binding machine which can be used for binding coils of various sizes in view of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a binding machine that can be used for binding coils of various sizes in view of the prior art, and the binding machine also has a punching function, and the punching function is integrated with the binding function.

[0008] The technical solution adopted by the present invention to solve at least one of the above technical problems is: a binding machine, comprising a base, the top surface of the base is respectively provided with:

[0009] A first pressing member;

[0010] A second pressing member is arranged opposite to the first pressing member, and in an initial state, there is an initial distance between the second pressing member and the first pressing member;

[0011] An adjusting mechanism, used for driving the second pressing member to adjust the initial spacing between the second pressing member and the first pressing member, and making the initial spacing match the size of the coil to be pressed;

[0012] The pressing driving member is used to drive the first pressing member to move toward the second pressing member in an initial state to press the coil therebetween.

[0013] Furthermore, the first pressing piece and the second pressing piece are both long strip-shaped plates, and the two are arranged vertically opposite to each other in the horizontal direction, so that the coil can be placed in the gap between the two along its own length direction. By designing the specific shapes of the first pressing piece and the second pressing piece and the specific arrangement of the two, the two can better cooperate to press the coil.

[0014] Furthermore, the distance between the upper ends of the first pressing piece and the second pressing piece is smaller than the distance between their lower ends, so as to prevent the coil from being squeezed and coming out from between the first pressing piece and the second pressing piece during the pressing process.

[0015] Furthermore, the pressing surfaces of the first pressing piece and the second pressing piece are respectively inclined inward from bottom to top along the length direction of the pressing pieces, so that the coil can be positioned between the first pressing piece and the second pressing piece, and the coil can be better prevented from falling out from between the two during the pressing process.

[0016] Furthermore, the first pressing part and the second pressing part are provided with anti-skid pads along their length directions respectively, so as to increase the friction between the coil and the pressing surfaces on both sides, thereby preventing the coil from moving (including upward slipping) during the pressing process and affecting the pressing effect.

[0017] Furthermore, the first pressing member and the second pressing member are both in the shape of long strips and are respectively arranged in parallel along the horizontal direction, and the above-mentioned adjustment mechanism includes:

[0018] An adjusting plate is arranged in the horizontal direction and fixed on one side of the second pressing member;

[0019] The adjusting hole is in the shape of a long strip and is provided on the adjusting plate, and its length direction intersects with the length direction of the second pressing piece and is inclined toward one side from the length direction of the second pressing piece;

[0020] The movable shaft can be limited to move back and forth in a direction parallel to the length direction of the second pressing part, and is vertically connected to the adjustment hole and can move back and forth along the length direction of the adjustment hole to drive the adjustment plate. In this way, when the movable shaft moves, it can drive the adjustment plate to move along the spacing direction between the first pressing part and the second pressing part, thereby driving the first pressing part, so that the first pressing part moves toward the second pressing part, or moves away from the second pressing part, changing the size of the initial spacing between the two. In addition, when the coil is pressed, since the movable shaft is limited along the spacing direction between the first pressing part and the second pressing part, the displacement of the second pressing part caused by the movement of the movable shaft is avoided.

[0021] Furthermore, the adjustment mechanism further includes a guide groove provided on the base, the guide groove extending in a direction parallel to the length direction of the second pressing piece, and one end of the movable shaft is embedded in the guide groove and can move back and forth along the guide groove. Through the cooperation between the movable shaft and the guide groove, the movable shaft is limited in the guide groove and can move back and forth in a direction parallel to the length direction of the second pressing piece.

[0022] Furthermore, the adjustment mechanism further comprises a moving plate, which extends horizontally, and the moving shaft is mounted on the moving plate, which is conducive to achieving a stable arrangement of the moving shaft.

[0023] Furthermore, a boss with a hollow interior is convexly provided on one side of the top surface of the base, the adjusting plate, the movable plate and the movable shaft are all accommodated in the inner cavity of the boss, and the guide grooves are respectively provided on the inner top surface and the inner bottom surface of the boss, and the upper and lower ends of the movable shaft are respectively embedded in the corresponding guide grooves and can move back and forth along the corresponding guide grooves.

[0024] In addition, one side of the boss is provided with an installation opening extending along the length direction of the second pressing part. The second pressing part is a plate member vertically arranged along the horizontal direction and can cover the installation opening, and the adjustment plate is fixed to the corresponding surface of the second pressing part along the length direction, and the other side of the boss is provided with a long strip-shaped guide opening, the length direction of the guide opening is parallel to the length direction of the second pressing part, and one end of the movable plate is provided with a shift block, which is embedded in the guide opening and can move back and forth along the guide opening. Thereby, the overall structure of the adjustment mechanism can be made more compact, and the movable shaft can move more smoothly, thereby ensuring the smooth movement of the first pressing part driven by the adjustment plate, and then ensuring the reliability of the initial spacing adjustment between the first pressing part and the second pressing part. In addition, by providing the shift block, it is convenient to shift the movable plate, thereby facilitating the adjustment of the initial spacing.

[0025] Furthermore, when the shift block is located at one end of the guide opening, the movable shaft is located at one end of the adjustment hole, the second pressing piece shields the installation opening, and the distance between the second pressing piece and the first pressing piece is the largest, while when the shift block is located at the other end of the guide opening, the movable shaft is located at the other end of the adjustment hole, the second pressing piece is located outside the installation opening, and the initial distance between the second pressing piece and the first pressing piece is the smallest. Thus, the first pressing piece can be stabilized in the initial state and the state with the smallest initial distance.

[0026] Furthermore, the pressing driving member is rotatably arranged on the top surface of the base and is provided with an elastic reset member, and is linked with the first pressing member through a transmission mechanism.

[0027] In the initial state, the coil to be pressed is placed in the gap between the first pressing part and the second pressing part, and the pressing driving part is rotated downward. The pressing driving part drives the first pressing part to move toward the second pressing part to press the coil placed between the first pressing part and the second pressing part. The elastic reset part is deformed so that the pressing driving part has a tendency to rotate upward and return to its initial state. In this way, the first pressing part can be driven by the rotation of the pressing driving part, and the pressing driving part automatically resets under the action of the elastic reset part after the pressing is completed. The operation is convenient and conducive to improving the user experience.

[0028] Furthermore, a punching mechanism is provided on the top surface of the base, and the punching mechanism includes a handle that can rotate up and down and a punching core, wherein the handle can press down the punching core to achieve punching, the pressing driving member is the handle, and the elastic reset member is a torsion spring installed on the rotating shaft of the handle. The present invention uses the handle of the punching mechanism as the pressing driving member, and the handle can achieve binding operation while achieving the punching drive. The punching function and the binding function are deeply integrated, which is conducive to the simplicity of the internal structure of the device.

[0029] Furthermore, the transmission mechanism includes a cam, a transmission gear set and a transmission rack, wherein the cam is arranged at the end of the connection end of the handle and can rotate around the rotating shaft of the handle, and the transmission gear set includes a first transmission gear meshed with the cam and a second transmission gear meshed with the transmission rack, wherein the first transmission gear meshes with the second transmission gear, and the transmission rack is connected to the first pressing part and extends along the spacing direction between the first pressing part and the second pressing part, and the rotation of the handle can drive the transmission rack to move back and forth along its own length direction. In this way, the handle rotates to drive the transmission gear set through the cam on it, and the transmission gear set drives the transmission rack to realize the movement of the first pressing part, so that the handle is transmitted to the first pressing part.

[0030] Furthermore, the first pressing member is a long strip-shaped plate member arranged vertically in the horizontal direction, and a horizontally extending sliding bottom plate is installed at the lower end of the first pressing member. The above-mentioned transmission racks are respectively arranged on both sides of the sliding bottom plate, and the sliding bottom plate can move back and forth along the length direction of each transmission rack.

[0031] The transmission mechanism also includes a gear seat arranged in a direction parallel to the length direction of the first pressing part, and the gear seat is provided with an upper axle and a lower axle located below the upper axle along its own length direction, wherein the first transmission gear is installed at both ends of the upper axle, and the second transmission gear is installed at both ends of the lower axle, and there are two cams arranged at intervals in a direction parallel to the length direction of the first pressing part, and each cam is meshed with the first transmission gear on the corresponding side, and at the same time, each transmission rack is meshed with the second transmission gear on the corresponding side. The above design enables the first pressing part to move back and forth more smoothly along the spacing direction between the first pressing part and the second pressing part under the drive of the handle.

[0032] Furthermore, the bottom surface of the gear seat is a plane and is slidably matched with the top surface of the sliding bottom plate, and a rollable ball is disposed at the bottom of the gear seat, the ball is at least partially exposed on the bottom surface of the gear seat, and the lowest point of the ball protrudes below the bottom surface of the gear seat. By designing the ball, the friction between the bottom surface of the gear seat and the top surface of the sliding bottom plate is reduced, so that the movement of the first pressing part can be smoother, the mutual friction between the parts is reduced, and the service life of the parts is extended.

[0033] Furthermore, a row of hanging poles arranged in a straight line and used to hang the coil along the length direction is provided on one side of the base. The coil is hung on each hanging pole along the length direction, so that the medium can be passed through the binding holes on the coil.

[0034] Furthermore, a baffle is included, and a plug hole for the baffle to be vertically inserted is provided on the top surface of the base, and when the baffle is inserted on the top surface of the base, the baffle can abut against the side of the medium to position the medium. Aligning the medium by the baffle is conducive to ensuring the accurate punching position.

[0035] Furthermore, the baffle is in the shape of a long strip, and the two ends of the baffle are respectively provided with plugs extending in the width direction thereof, and the above-mentioned plug holes are arranged on the top surface of the above-mentioned base and are respectively inserted into the plugs, and the plug holes are arranged into a preset array, in which the plugs at one end of the baffle are inserted into the corresponding plug holes according to the working position of the medium, and the plugs at the other end can always be inserted into another corresponding plug hole. This makes it convenient for users to adjust the position of the baffle according to different media sizes, different punching mechanisms, etc., and improve the user experience.

[0036] Furthermore, a receiving groove for receiving the baffle is concavely formed on the base, and when the baffle is received in the receiving groove, the baffle is hidden under the outer surface of the base, so as to avoid the baffle being lost when not in use.

[0037] Furthermore, a storage box for storing debris generated by punching is slidably mounted on the bottom of the base, and the storage box can extend outward from the base in a horizontal direction. The debris is collected in the storage box to prevent the debris from scattering, and it is also convenient to dump the debris collected in the storage box.

[0038] Compared with the prior art, the advantages of the present invention are: the present invention uses an adjustment mechanism to adjust the size of the initial spacing between the first pressing member and the second pressing member, and makes the initial spacing size match the size of the coil to be pressed, and drives the first pressing member to move toward the second pressing member through a pressing driving member to press the coil between the two. It can be seen that the present invention can realize the pressing of coils of various sizes (6.4mm to 16mm), thereby realizing the binding of products using coils of different sizes, such as notebooks, calendars, photo albums, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention is further described in detail below with reference to the accompanying drawings.

[0055] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0056] like Figures 1 to 15 As shown, a binding machine includes a base 1, and a first pressing piece 21, a second pressing piece 22, an adjustment mechanism 3 and a pressing drive are respectively arranged on the top surface of the base 1. The second pressing piece 22 is arranged opposite to the first pressing piece 21, and in the initial state, there is an initial spacing between the second pressing piece 22 and the first pressing piece 21. The adjustment mechanism 3 is used to drive the second pressing piece 22 to adjust the initial spacing between the second pressing piece 22 and the first pressing piece 21, and make the initial spacing match the size of the coil to be pressed. The pressing drive is used to drive the first pressing piece 21 to move toward the second pressing piece 22 in the initial state to press the coil between the two.

[0057] As can be seen from the above, the present invention uses the adjustment mechanism 3 to adjust the size of the initial spacing between the first pressing member 21 and the second pressing member 22, and makes the initial spacing size match the size of the coil to be pressed, and drives the first pressing member 21 to move toward the second pressing member 22 through the pressing driving member to press the coil between the two. It can be seen that the present invention can realize the pressing of coils of various sizes (6.4mm to 16mm), thereby realizing the binding of products using coils of different sizes, such as notebooks, calendars, photo albums, etc.

[0058] Preferably, the first pressing member 21 and the second pressing member 22 are both long strip-shaped plates, and the two are arranged vertically opposite to each other in the left-right direction, so that the coil can be placed in the gap between the two along its own length direction. Figure 1 and Figure 7 By designing the specific shapes of the first pressing piece 21 and the second pressing piece 22 and the specific arrangement of the two, the two can better cooperate with each other to press the coil.

[0059] More preferably, if Figure 7 As shown, the distance between the upper ends of the first pressing piece 21 and the second pressing piece 22 is smaller than the distance between the lower ends thereof, so that the coil can be prevented from being squeezed out from between the first pressing piece 21 and the second pressing piece 22 during the pressing process. In this embodiment, specifically, the pressing surface of the first pressing piece 21 and the pressing surface of the second pressing piece 22 are respectively inclined inward from bottom to top along the length direction of the pressing pieces, so that the coil can be positioned between the first pressing piece 21 and the second pressing piece 22, so as to better prevent the coil from being removed from between the two during the pressing process. Preferably, the pressing surface of the first pressing piece 21 and the pressing surface of the second pressing piece 22 are respectively arranged with anti-skid pads 211 and 221 along their own length direction. The anti-skid pads 211 and 221 are used to increase the friction between the coil and the pressing surfaces on both sides, so as to prevent the coil from moving (including upward removal) during the pressing process and affecting the pressing effect.

[0060] Further, if Figure 4 and Figure 5 As shown, the adjustment mechanism 3 includes an adjustment plate 31, an adjustment hole 311 and a movable shaft 32. The adjustment plate 31 is arranged in the horizontal direction and fixed on one side of the second pressing piece 22. The adjustment hole 311 is in the shape of a long strip and is provided on the adjustment plate 31. The length direction of the adjustment hole 311 intersects with the length direction of the second pressing piece 22 and is inclined toward one side from the length direction of the second pressing piece 22. In this embodiment, specifically, the second straight line extends in the left-right direction, the third straight line extends in the front-back direction, and the first straight line extends from front to back toward the left.

[0061] Furthermore, the movable shaft 32 can be limited to move back and forth in a direction parallel to the length direction of the second pressing piece 22, and vertically penetrates the adjustment hole 311 and can move back and forth in the length direction of the adjustment hole 311 to drive the adjustment plate 31. In this way, when the movable shaft 32 moves, it can drive the adjustment plate 31 to move along the spacing direction between the first pressing piece 21 and the second pressing piece 22, thereby driving the first pressing piece 21, so that the first pressing piece 21 moves toward the second pressing piece 22, or moves away from the second pressing piece 22, thereby changing the size of the initial spacing between the two. In addition, when the coil is pressed, since the movable shaft 32 is limited in the spacing direction between the first pressing piece 21 and the second pressing piece 22, the displacement of the second pressing piece 22 caused by the movement of the movable shaft 32 can be avoided.

[0062] Preferably, if Figure 5 As shown, the adjustment mechanism 3 further includes a guide groove 111 provided on the base 1, the guide groove 111 extending in a direction parallel to the length direction of the second pressing piece 22, and one end of the movable shaft 32 is embedded in the guide groove 111 and can move back and forth along the guide groove 111. The movable shaft 32 is limited in the guide groove 111 by the cooperation between the movable shaft 32 and the guide groove 111, and can move back and forth in a direction parallel to the length direction of the second pressing piece 22. In addition, the adjustment mechanism 3 further includes a movable plate 33, the movable plate 33 extending horizontally and arranged on the upper side or the lower side of the adjustment plate 31, and the movable shaft 32 is installed on the movable plate 33, which is conducive to realizing the stable setting of the movable shaft 32.

[0063] In this embodiment, specifically, Figure 1 , Figure 6 as well as Figure 7 As shown, a hollow boss 11 is convexly provided on one side of the top surface of the base 1, and the adjustment plate 31, the moving plate 33 and the moving shaft 32 are all accommodated in the inner cavity of the boss 11, and the guide grooves 111 are respectively provided on the inner top surface and the inner bottom surface of the boss 11, and the upper and lower ends of the moving shaft 32 are respectively embedded in the corresponding guide grooves 111, and can move back and forth along the corresponding guide grooves 111. The adjustment plates 31 are divided into two pieces, and the two adjustment plates 31 are spaced apart from each other, and the moving plate 33 is sandwiched between the two adjustment plates 31, so as to facilitate the smooth movement of the moving plate 33, and the adjustment holes 311 are respectively provided on each adjustment plate 31, and the upper and lower ends of the moving shaft 32 on the moving plate 33 are respectively penetrated in the adjustment holes 311 of the corresponding adjustment plates 31.

[0064] Furthermore, one side of the boss 11 is a vertical wall and is provided with a mounting opening 113 extending left and right, the second pressing member 22 is a vertically arranged plate and can cover the mounting opening 113, and each of the adjustment plates 31 is fixed to the corresponding surface of the second pressing member 22 along the length direction. In this embodiment, preferably, each adjustment plate 31 and the second pressing member 22 are an integral part (such as Figure 5 As shown). A long strip-shaped guide opening 112 is formed on the other side of the boss 11, and the length direction of the guide opening 112 is parallel to the length direction of the second pressing member 22. A shift block 34 is formed on one end of the movable plate 33, and the shift block 34 is embedded in the guide opening 112 and can move back and forth along the guide opening 112. Figure 2 As shown. The overall structure of the adjustment mechanism 3 can be made more compact, and the movable shaft 32 can move more smoothly, thereby ensuring the smooth movement of the first pressing member 21 driven by the adjustment plate 31, and then ensuring the reliability of the initial spacing adjustment between the first pressing member 21 and the second pressing member 22. In addition, the setting of the shifting block 34 facilitates the shifting of the movable plate 33, thereby facilitating the adjustment of the above-mentioned initial spacing.

[0065] Furthermore, when the shift block 34 is located at one end of the guide opening 112, the movable shaft 32 is located at one end of the adjustment hole 311, the second pressing member 22 shields the installation opening 113, and the distance between the second pressing member 22 and the first pressing member 21 is the largest. When the shift block 34 is located at the other end of the guide opening 112, the movable shaft 32 is located at the other end of the adjustment hole 311, the second pressing member 22 is located outside the installation opening 113, and the initial distance between the second pressing member 22 and the first pressing member 21 is the smallest, so that the first pressing member 21 can be stabilized in the initial state and the state with the smallest initial distance.

[0066] Further, preferably, the pressing drive member is rotatably arranged on the top surface of the base 1 and is provided with an elastic reset member, and is linked with the first pressing member 21 through the transmission mechanism 5. In the initial state, the coil to be pressed is placed in the gap between the first pressing member 21 and the second pressing member 22, and the pressing drive member is rotated downward. The pressing drive member drives the first pressing member 21 to move toward the second pressing member 22 to press the coil placed between the first pressing member 21 and the second pressing member 22. The elastic reset member is deformed so that the pressing drive member has a tendency to rotate upward to restore to its initial state. In this way, the first pressing member 21 can be driven by the rotation of the pressing drive member, and the pressing drive member is automatically reset under the action of the elastic reset member after the pressing is completed. The operation is convenient and conducive to improving the user experience.

[0067] Furthermore, the binding machine in this embodiment also has a punching function, so a punching mechanism 4 is also provided on the top surface of the base 1. The punching mechanism 4 includes a handle 41 that can be rotated up and down and a punching core 42. Figure 6 As shown. The handle 41 can press down the punching mechanism 42 to punch holes, the pressing driving member is the handle 41, and the elastic reset member is a torsion spring 43 installed on the rotating shaft 410 of the handle 41. It can be seen that the present invention uses the handle 41 of the punching mechanism 4 as the pressing driving member, and the handle 41 can realize the binding operation while realizing the punching drive. The punching function and the binding function are deeply integrated, which is conducive to the simplicity of the internal structure of the device.

[0068] Further, in this embodiment, if Figure 7 , Fig.11 , Fig.13 , Fig.14 as well as Fig.15 As shown, the transmission mechanism 5 includes a cam 51, a transmission gear set 52 and a transmission rack 531, wherein the cam 51 is arranged at the end of the connection end 411 of the handle 41 and can rotate around the rotating shaft 410 of the handle 41. The transmission gear set 52 includes a first transmission gear 521 meshed with the cam 51 and a second transmission gear 522 meshed with the transmission rack 531, wherein the first transmission gear 521 meshes with the second transmission gear 522. The transmission rack 531 is connected to the first pressing part 21 and extends along the spacing direction between the first pressing part 21 and the second pressing part 22, and the rotation of the handle 41 can drive the transmission rack 531 to move back and forth along its own length direction. In this way, the handle 41 rotates and drives the transmission gear set 52 through the cam 51 thereon, and drives the transmission rack 531 through the transmission gear set 52 to realize the movement of the first pressing part 21, so that the handle 41 is transmitted to the first pressing part 21.

[0069] Furthermore, a horizontally extending sliding base plate 53 is installed at the lower end of the first pressing member 21, and the transmission racks 531 are respectively arranged on the left and right sides of the sliding base plate 53, and the sliding base plate 53 can move back and forth along the length direction of each transmission rack 531. The transmission mechanism 5 also includes a gear seat 54 arranged along the left and right directions, and an upper wheel shaft 541 and a lower wheel shaft 542 located below the upper wheel shaft 541 are respectively arranged on the gear seat 54 along the left and right directions. Among them, the first transmission gear 521 is respectively installed at both ends of the upper wheel shaft 541, and the second transmission gear 522 is respectively installed at both ends of the lower wheel shaft 542. There are two cams 51 and they are spaced apart in the left and right directions. Each cam 51 is meshed with the first transmission gear 521 on the corresponding side, and at the same time, each transmission rack 531 is meshed with the second transmission gear 522 on the corresponding side.
