[0008] When the moving member is in the standby position, the first cutting portion and the second cutting portion can simultaneously abut the strap buckle, and one end of the strap body passing through the strap buckle can pass through the cutting slit and enter between the clamping surface and the traction surface along the first direction after passing through the cutting slit, and abut against the clamping surface and the traction surface; the second elastic member continuously pushes the clamping member to approach the traction member and makes the portion of the strap body abutting against the clamping surface continuously adhere to the traction surface, and the traction member can drive the portion of the strap body abutting against the clamping member to continue to move along the first direction through the traction surface; after a portion of a preset length of the strap body enters the cutting slit, the traction member can drive the clamping member to move along the first direction through the strap body, thereby driving the moving member to move along the first direction, so that the moving member moves from the standby position to the cutting position, and the moving member drives the first cutting body to rotate relative to the guide bracket, and the first cutting portion approaches the second cutting portion and closes the cutting slit.

[0042] The following Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 The utility model introduces a cable tie cutting device, wherein Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 The cable tie is not shown. The utility model provides a cable tie cutting device for tightening and cutting the cable tie. The cable tie includes a cable tie buckle and a cable tie body 30. One end of the cable tie body 30 is connected to the cable tie buckle, and the other end passes through the cable tie buckle. The cable tie includes a guide bracket 100, a cutting assembly 200 and a clamping assembly 300.

[0043] Please refer to Figure 1 , Figure 2 , Figure 4As shown, the cutting assembly 200 includes a first cutting piece 210 and a second cutting piece 220; the first cutting piece 210 includes a first cutting portion 211 and a first cutting body 212, the first cutting body 212 is rotatably connected to the guide bracket 100, and the first cutting portion 211 is connected to the first cutting body 212; the second cutting piece 220 includes a second cutting portion 221 and a second cutting body 222, the second cutting body 222 is connected to the guide bracket 100, and the second cutting portion 221 is connected to the second cutting body 222; the first cutting portion 211 and the second cutting portion 221 are arranged in sequence along the second direction, and define a cutting seam 230.

[0044] Regarding the function of the cutting seam 230, specifically, according to some embodiments of the present invention, the first cutting portion 211 and the second cutting portion 221 are arranged along the second direction (ie Figure 1 , Figure 2 , Figure 4 The first cutting portion 211 and the second cutting portion 221 define a cutting seam 230, and the cutting seam 230 connects the first cutting portion 211 and the second cutting portion 221 on one side of the first direction (i.e. Figure 1 , Figure 2 , Figure 4 The front side in the first direction) and the opposite side in the first direction (i.e. Figure 1 , Figure 2 , Figure 4 and enables the end of the cable tie body 30 that passes through the cable tie buckle to pass through in the first direction.

[0045] Please refer to Figure 2 , Figure 3 , Figure 4 As shown, the clamping assembly 300 includes a moving member 310, a pulling member 320, a clamping member 330, a first elastic member 340 and a second elastic member 350; the moving member 310 has a standby position A and a cutting position B, the standby position A and the cutting position B are arranged along a first direction, and the first direction is perpendicular to the second direction; the moving member 310 is slidably connected to the guide bracket 100, and can slide from the standby position A to the cutting position B along the first direction relative to the guide bracket 100, and the first cutting body 212 is transmission-connected to the moving member 310. The first elastic member 340 extends along the first direction, one end of the first elastic member 340 is connected to the guide bracket 100, and the other end of the first elastic member 340 is connected to the moving member 310, and the first elastic member 340 can provide an elastic force in the opposite direction of the first direction to the moving member 310.

[0046] Since the first elastic member 340 can exert an elastic force in the opposite direction of the first direction on the moving member 310, the moving member 310 needs to overcome the elastic force exerted by the first elastic member 340 when moving from the standby position A to the cutting position B along the first direction. Figure 2 , Figure 3 As shown, the first elastic member 340 is arranged along the first direction (ie Figure 3 The first elastic member 340 extends forwardly from the movable member 310, and the rear end of the first elastic member 340 is connected to the movable member 310, and the front end of the first elastic member 340 is connected to the guide bracket 100; the movable member 310 compresses the first elastic member 340 during the process of moving forward, so that the first elastic member 340 applies a backward elastic force to the movable member 310. According to other embodiments of the present invention, the movable member 310 stretches the first elastic member 340 during the process of moving forward, so that the first elastic member 340 applies a backward pulling force to the movable member 310.

[0047] Please refer to Figure 3 As shown, the clamping member 330 and the pulling member 320 are arranged along the second direction and are located on one side of the first cutting portion 211 and the second cutting portion 221 in the first direction.

[0048] It has been mentioned above that the cutting seam 230 defined by the first cutting portion 211 and the second cutting portion 221 can allow one end of the cable tie body 30 to pass through the cable tie buckle along the first direction. Based on the above embodiment, since the clamping member 330 and the traction member 320 are located on one side of the first cutting portion 211 and the second cutting portion 221 in the first direction, the end of the cable tie body 30 passing through the cutting seam 230 along the first direction can contact the clamping member 330 and / or the traction member 320.

[0049] Please refer to Figure 3 , Figure 4 , Figure 5 As shown, the clamping member 330 is rotatably connected to the moving member 310, and the rotation axis of the clamping member 330 relative to the moving member 310 is the first rotation axis 333, the first rotation axis 333 is parallel to the third direction, and the first direction, the second direction and the third direction are perpendicular to each other; the clamping member 330 has a clamping surface 331, and the clamping surface 331 is inclined relative to the first direction and faces the cutting seam 230. The second elastic member 350 is located on one side of the first rotation axis 333 in the first direction, and one end of the second elastic member 350 facing the opposite direction of the second direction is connected to the moving member 310, and the other end of the second elastic member 350 facing the second direction can abut against the clamping member 330; the traction member 320 is movably connected to the guide bracket 100, and the traction member 320 has a traction surface 321, which is arranged relative to the clamping surface 331 and is located on one side of the cutting seam 230 in the second direction.

[0050] When the second elastic member 350 is compressed, it will continue to apply elastic force to both ends. In the absence of external force, the clamping member 330 abutting against one end of the second elastic member 350 will be subjected to the elastic force in the second direction, thereby rotating around the first rotation axis 333, approaching the traction member 320 located on the one side of the clamping member 330 in the second direction and approaching the cutting seam 230 at the same time; since the clamping surface 331 is inclined relative to the first direction and faces the cutting seam 230, when the cable tie body 30 continues to move in the first direction and contacts the clamping surface 331 after passing through the cutting seam 230 along the first direction, the thrust of the cable tie body 30 can enable the clamping member 330 to overcome the elastic force of the second elastic member 350 in the second direction, and drive the clamping member 330 to rotate, so that the clamping surface 331 is away from the traction member 320 and away from the cutting seam 230.

[0051] Please refer to Figure 4 , Figure 5 As shown, since the clamping surface 331 is inclined relative to the first direction and toward the cutting seam 230, and the traction surface 321 is located on the side of the cutting seam 230 in the second direction, the cable tie body 30 can be guided by the clamping surface 331 after contacting the clamping surface 331 and bend in the second direction and approach the traction member 320.

[0052] Please refer to Figure 2 , Figure 4 , Figure 7 As shown, when the movable member 310 is located at the standby position A, the first cutting portion 211 and the second cutting portion 221 can abut against the tie buckle at the same time, and one end of the tie body 30 passing through the tie buckle can pass through the cutting slit 230 and after passing through the cutting slit 230, enter between the clamping surface 331 and the traction surface 321 along the first direction and abut against the clamping surface 331 and the traction surface 321.

[0053] It should be noted that the present invention does not limit the specific manner in which the cable tie body 30 passes through one end of the cable tie buckle and enters between the clamping surface 331 and the pulling surface 321. According to some embodiments of the present invention, please refer to Figure 4 , Figure 5 As shown, the cable tie body 30 can first abut the clamping surface 331 and push the clamping member 330 to move forward and upward around the first rotation axis 333, and expose the traction surface 321. The cable tie body 30 can abut the traction surface 321 while abutting the clamping surface 331. According to other embodiments of the present invention, please refer to Figure 6 As shown, the cable tie body 30 can first abut against the traction surface 321 , and simultaneously abut against the clamping surface 331 during the process of the cable tie body 30 moving forward.

[0054] Please refer to Figure 2 , Figure 4 , Figure 7As shown, the second elastic member 350 continuously pushes the clamping member 330 close to the traction member 320 and makes the portion of the cable tie body 30 abutting against the clamping surface 331 continue to adhere to the traction surface 321. The traction member 320 can drive the portion of the cable tie body 30 abutting against the clamping member 330 to continue to move along the first direction through the traction surface 321.

[0055] The utility model drives the cable tie body 30 to move in the first direction through the traction surface 321 of the traction member 320, so that more parts of the cable tie body 30 pass through the cable tie buckle to achieve the tightening of the cable tie. For the specific form of driving the cable tie body 30 by the traction surface 321 according to some embodiments of the utility model, please refer to Figure 4 , Figure 5 As shown, the traction member 320 extends along the first direction and is rotatably connected to the guide bracket 100. The rotation axis of the traction member 320 relative to the guide bracket 100 is the second rotation axis 323, and the second rotation axis 323 is parallel to the first direction; the traction member 320 includes a threaded portion 322, the threaded portion 322 extends along the first direction and is arranged around the second rotation axis 323, the threaded portion 322 has a traction surface 321, and can engage with the toothed structure of the cable tie body 30. When the traction member 320 rotates around the second rotation axis 323, the traction surface 321 of the threaded portion 322 can drive the toothed structure in contact with the traction surface 321 to move forward in the first direction, thereby driving the cable tie body 30 to move forward. In the above embodiment, the clamping plate continuously pushes the cable tie body 30 in the second direction, so that the toothed structure of the cable tie body 30 can stably receive the pushing force of the traction surface 321 and move forward in the first direction, and the portion of the cable tie body 30 located between the first cutting portion 211 and the traction member 320 is bent in the second direction and engaged with the traction member 320, so that the traction surface 321 can continuously pull the cable tie body 30 in the first direction.

[0056] It should be noted that the traction surface 321 in the present invention should be a partial surface of the threaded portion 322 that can engage with the toothed structure of the cable tie body 30 in the second direction, rather than the entire surface of the threaded portion 322. Figure 5 As shown, according to some embodiments of the present invention, after a portion of the strap body 30 that was originally pushed by the clamping member 330 along the second direction is no longer affected by the clamping member 330, the internal stress between the various parts of the strap body 30 may cause the portion of the strap body 30 that was originally pushed by the clamping member 330 to move away from the threaded portion 322, and the threaded portion 322 will no longer apply a pushing force in the first direction to this portion of the strap body 30.

[0057] According to other embodiments of the present invention, please refer to Figure 6 As shown, the traction member 320 adopts a conveyor belt structure, and the surface of the conveyor belt facing the opposite direction of the second direction forms a traction surface 321; Figure 6 Observing from the direction of the paper, when the conveyor belt rotates clockwise, the traction surface 321 can continuously drive the tie body 30 to move in the first direction through friction. In the above embodiment, the clamping plate continuously pushes the tie body 30 in the second direction, so that the tie body 30 can be subjected to sufficient friction from the traction surface 321 and move along the first direction.

[0058] Without departing from the inventive concept of the present utility model, those skilled in the art may also use other structural forms to realize the driving of the traction surface 321 on the cable tie body 30. According to other embodiments of the present utility model, please refer to Figure 6 As shown, the traction member 320 adopts a conveyor belt structure, and teeth that can mesh with the toothed structure on the cable tie body 30 are evenly arranged on the circumference of the conveyor belt structure. When the conveyor belt rotates clockwise, the teeth on the transmission belt structure can drive the cable tie body 30 to move in the first direction.

[0059] As for the power source of the traction member 320, since the traction member 320 only needs to work continuously to pull the cable tie body 30, the cable tie cutting device can drive the traction member 320 in the form of electricity, pneumatics, hydraulics, etc. without departing from the inventive concept of the utility model to realize the automatic operation of the traction member 320. In some embodiments, please refer to Figure 1 , Figure 2 As shown, the cable tie cutting device further includes a handle 10 and an electric control switch 20, wherein a power supply and a motor are arranged inside the handle 10, the power supply, the electric control switch 20 and the motor are electrically connected to each other, the motor is used to drive the traction member 320, and the staff can control the electric control switch 20 to start or stop the motor from driving the traction member 320. Compared with other driving forms, using electric drive to drive the traction member 320 is more conducive to the lightweight of the cable tie cutting device and is convenient for the staff to use.

[0060] As mentioned above, the traction member 320 can continuously pull the cable tie body 30 to move along the first direction through the traction surface 321. After a portion of the preset length of the cable tie body 30 enters the cutting seam 230, the traction member 320 can drive the clamping member 330 to move along the first direction through the cable tie body 30, thereby driving the moving member 310 to move along the first direction, so that the moving member 310 moves from the standby position A to the cutting position B. The moving member 310 drives the first cutting body 212 to rotate relative to the guide bracket 100, and the first cutting portion 211 approaches the second cutting portion 221 and closes the cutting seam 230.

[0061] Please refer to Figure 5As shown, specifically, for a cable tie that needs to be tightened to a certain degree, since the cable tie buckle abuts against the first cutting portion 211 and the second cutting portion 221, when the cable tie body 30 moves along the first direction, more parts of the cable tie body 30 will pass through the cable tie buckle, so that the cable tie is gradually tightened, and the end of the cable tie body 30 close to the cable tie buckle will generate a gradually increasing traction force on the part of the cable tie body 30 passing through the cable tie buckle. The combined effect of the traction force generated by the cable tie body 30 itself, the pressure of the clamping member 330 and the force of the traction member 320 will make the part between the cutting seam 230 and the clamping member 330 (that is, Figure 5 The portion between the position where the middle clamping member 330 presses the cable tie body 30 and the cutting seam 230 is gradually straightened, and this portion will move in the opposite direction of the second direction to gradually increase the contact area between this portion and the clamping surface 331, and gradually increase the friction force of this portion on the clamping member 330, and gradually increase the component of the friction force along the first direction.

[0062] Regarding the surface treatment of the clamping surface 331, those skilled in the art may set anti-skid patterns on the clamping surface 331 to increase the friction between the clamping surface 331 and the cable tie body 30. As a preferred solution, please refer to Figure 5 As shown, in some embodiments, the clamping member 330 has a plurality of anti-skid grooves 332, which all extend along the third direction and are arranged on the clamping surface 331. In the above scheme, on the basis of increasing the roughness of the clamping surface 331, when the cable tie body 30 enters the anti-skid groove 332 due to its own deformation, the inner wall of the anti-skid groove 332 can also exert a force in the first direction on the cable tie body 30, thereby preventing the cable tie body 30 from moving in the opposite direction along the first direction.

[0063] As mentioned above, the moving member 310 needs to overcome the elastic force applied by the first elastic member 340 in the process of moving from the standby position A to the cutting position B along the first direction. After a portion of the preset length of the cable tie body 30 enters the cutting slit 230, the cable tie has been tightened to a certain extent; the friction force applied by the cable tie body 30 to the clamping member 330 can overcome the elastic force of the first elastic member 340, and the moving member 310 starts to move from the standby position A along the first direction. In the process of the moving member 310 moving from the standby position A to the cutting position B, the clamping member 330 connected to the moving member 310 continues to push the cable tie body 30 in the second direction, and the cable tie body 30 continues to move in the first direction under the influence of the clamping member 330 and the traction member 320, so that the cable tie is further tightened to a preset degree; at the same time, the moving member 310 drives the first cutting body 212 to rotate through the transmission connection with the first cutting body 212, and the first cutting portion 211 connected to the first cutting body 212 rotates together.

[0064] Without departing from the inventive concept of the present utility model, those skilled in the art may reasonably preset the tension of the first elastic member 340 to adjust the elastic force that the moving member 310 needs to overcome before moving along the first direction. Figure 3 , Figure 4 , Figure 7 As shown, in some embodiments, the clamping assembly 300 further includes an adjusting member 360, the adjusting member 360 is connected to the guide bracket 100, one end of the first elastic member 340 is connected to the adjusting member 360, and the other end of the first elastic member 340 is connected to the moving member 310, and the adjusting member 360 can move relative to the guide bracket 100 along the first direction and the opposite direction of the first direction, and remain relatively still with the guide bracket 100 during the process of the moving member 310 moving from the standby position A to the cutting position B. The staff can move the adjusting member 360 relative to the guide bracket 100 along the first direction and the opposite direction of the first direction and simultaneously increase or decrease the elastic force of the first elastic member 340, thereby adjusting the tension of the cable tie cutting device on the cable tie. In some embodiments, the adjusting member 360 is threadedly connected to the guide bracket 100, and the staff can rotate the adjusting member 360 to move the adjusting member 360 relative to the guide bracket 100 along the first direction and the opposite direction of the first direction. In other embodiments, the relative position between the adjusting member 360 and the guide bracket 100 can be fixed by a pin, and the staff can move the adjusting member 360 relative to the guide bracket 100 along the first direction and the opposite direction of the first direction after pulling out the pin.

[0065] When the moving member 310 moves to the cutting position B, the first cutting portion 211 contacts the second cutting portion 221 and closes the cutting seam 230 , and the portion of the strap body 30 extending relative to the strap buckle is cut by the first cutting portion 211 and the second cutting portion 221 .

[0066] The moving member 310 adjusts the rotational position of the first cutting portion 211 through the transmission connection relationship with the first cutting body 212, and finally closes the cutting seam 230. Without departing from the inventive concept of the utility model, the utility model does not limit the transmission connection relationship between the moving member 310 and the first cutting body 212. Those skilled in the art can realize the transmission of the moving member 310 to the first cutting body 212 by combining the common technical means in the field.

[0067] In particular, as a preferred solution for transmission connection between the first cutting body 212 and the moving member 310, in some embodiments, please refer to Figure 8 , Fig. 9As shown, the first cutting body 212 is rotatably connected to the guide bracket 100 through the rotating connecting member 240, and the rotation axis of the first cutting body 212 of the guide bracket 100 relative to the guide bracket 100 is the third rotation axis 2123, and the third rotation axis 2123 is in the rotating connecting member 240; the first cutting portion 211 is located on the side of the third rotation axis 2123 opposite to the first direction; the first cutting body 212 has a lifting surface 2121, the lifting surface 2121 faces the moving member 310 and is inclined in the second direction, and the lifting surface 2121 is located on one side of the third rotation axis 2123 in the first direction; the moving member 310 pushes the lifting surface 2121 in the process of moving to the cutting position B, driving the first cutting body 212 to rotate relative to the guide bracket 100. When the moving member 310 moves to the cutting position B, it applies a supporting force to the lifting surface 2121 of the first cutting body 212. Since the lifting surface 2121 is inclined in the second direction, the supporting force on the first cutting body 212 includes a component force in the opposite direction of the second direction. Then, the lifting surface 2121 of the first cutting body 212 moves in the opposite direction of the second direction, and the first cutting portion 211 moves in the second direction and approaches the second cutting portion 221, and finally the cutting seam 230 is closed. The above embodiment directly realizes the movement of the first cutting portion 211 through the supporting effect of the moving member 310 on the first cutting body 212, and the structure is simpler, which is conducive to reducing production costs.

[0068] The above fully describes the process of the cable tie cutting device tightening and cutting the cable tie. In the above process, the cable tie cutting device can automatically tighten the cable tie and cut the portion of the cable tie body 30 that passes through the cable tie buckle, ensuring the consistency of the tightening degree and cutting flatness of the cable tie; the staff only needs to make the cable tie body 30 pass through one end of the cable tie buckle, insert it into the cutting slit 230 and enter between the clamping surface 331 and the traction surface 321, and make the cable tie buckle abut against the first cutting portion 211 and the second cutting portion 221 at the same time, and the operating burden is greatly reduced.

[0069] On the basis of the above solution, other improvements can be made to the cable tie cutting device.

[0070] For further information, please refer to Figure 8 , Fig. 9As shown, in some embodiments, the rotation axis of the first cutting body 212 relative to the guide bracket 100 is the third rotation axis 2123, and the cable tie cutting device includes a third elastic member 500, the third elastic member 500 is connected to the guide bracket 100 and is located on the side of the third rotation axis 2123 in the opposite direction of the first direction, the third elastic member 500 is abutted against the first cutting body 212, and can apply an elastic force in the opposite direction of the second direction to the first cutting body 212; the first cutting body 212 also has a limiting plane 2122, and the limiting plane 2122 faces the second direction; the moving member 310 includes a limiting portion 313, the limiting portion 313 is located on the side of the third rotation axis 2123 in the first direction, and the limiting portion 313 abuts against the limiting plane 2122 when the moving member 310 is in the standby position A. The above-mentioned embodiment can apply elastic force to the first cutting body 212 through the third elastic member 500 when the movable member 310 is in the standby position A, thereby preventing the first cutting portion 211 from directly contacting the second cutting portion 221 and closing the cutting seam 230 without being subjected to other external forces, thereby preventing the cable tie body 30 from being unable to pass through the cutting seam 230; on the other hand, the limiting portion 313 of the movable member 310 can abut against the limiting plane 2122, thereby controlling the opening degree of the cutting seam 230, and ensuring that the cable tie buckle can abut against the first cutting portion 211 and the second cutting portion 221 at the same time.

[0071] The above-mentioned solution of moving the first cutting portion 211 by supporting the lifting surface 2121 through the moving member 310 has been described. Figure 2 , Figure 7 , Figure 8As shown, the first cutting body 212 also has a limiting plane 2122, which faces the second direction and is located on one side of the third rotation axis 2123 in the first direction; the lifting surface 2121 is smoothly connected to one side of the limiting plane 2122 in the first direction; the moving member 310 abuts against the limiting plane 2122 when in the standby position; in the process of moving from the standby position A to the cutting position B, the moving member 310 abutting against the limiting plane 2122 transitions to abutting against the lifting surface 2121. Through the above scheme, in the process of the moving member 310 moving from the standby position A to the cutting position B, that is, before the first cutting part 211 and the second cutting part 221 cut the cable tie body 30, the opening degree of the cutting seam 230 will be limited by the limiting plane 2122 and will not increase, ensuring that the cable tie buckle can stably abut against the first cutting part 211 and the second cutting part 221 during the cutting process. On the other hand, during the movement along the first direction, the movable member 310 will sequentially abut the limiting plane 2122 and the lifting surface 2121, and finally push the lifting surface 2121 and drive the first cutting body 212 to rotate relative to the guide bracket 100; the cable tie cutting device can change the contact position of the movable member 310 and the first cutting body 212 by the movement of the movable member 310 along the first direction, so that the movable member 310 can adjust the posture of the first cutting body 212 during the movement along the first direction, thereby adjusting the opening size of the cutting seam 230, thereby realizing the cutting function of the cable tie cutting device on the cable tie body 30.

[0072] For further information, please refer to Figure 7 , Fig. 9 As shown, in some embodiments, the guide bracket 100 has a receiving channel 110, which extends along the first direction. The receiving channel 110 has a receiving port 111 at one end opposite to the first direction, and the receiving port 111 is connected to the cutting slit 230; the cable tie body 30 enters the receiving port 111 after passing through the cutting slit 230, and then enters between the clamping surface 331 and the traction surface 321. The receiving channel 110 can limit the movement of the cable tie body 30 along the third direction and the reverse direction of the third direction. When the moving member 310 moves to the cutting position B, the part of the cable tie body 30 attached to the traction surface 321 is separated from the receiving channel 110. The receiving channel 110 of the above embodiment can limit the movement of the cable tie body 30 along the third direction and the reverse direction of the third direction through the inner wall, thereby ensuring that the cable tie body 30 will not be separated from between the clamping member 330 and the traction member 320 during the process of the traction member 320 pulling the cable tie body 30.

[0073] Furthermore, in some embodiments, the cable tie cutting device further includes a collecting bin 400, which is connected to the guide bracket 100 and has a receiving chamber 410; the receiving channel 110 is connected to the receiving chamber 410 at the end in the first direction. Through the above solution, the receiving chamber 410 can collect the portion of the cable tie body 30 that is separated from the receiving channel 110, thereby preventing the cut cable tie body 30 from being separated from the cable tie cutting device and causing pollution to the working environment.

[0074] Please refer to Figure 1 , Fig. 9 As shown, as a preferred solution, in some embodiments, the collecting bin 400 is connected to one side of the guide bracket 100 in the third direction, and the guide bracket 100 further has a collecting channel 120, which extends along the third direction, one end of which is connected to the end of the receiving channel 110 in the first direction, and the other end of which is connected to the accommodating chamber 410. The collecting channel 120 can receive the cable tie body 30 from the receiving channel 110, and the cable tie body 30 can enter the accommodating chamber 410 under the guidance of the inner wall of the collecting channel 120 after entering the collecting channel 120. The collecting channel 120 can change the transportation direction of the cable tie body 30, so that the collecting bin 400 can be set on one side of the receiving channel 110 in the third direction, thereby reducing the space occupied by the cable tie cutting device in the first direction and the second direction.

[0075] Please refer to Fig. 9 As shown, further, in some embodiments, the guide bracket 100 also has a guide channel 130, which extends along the first direction, one end of the guide channel 130 is connected to the cutting slit 230, and the other end of the guide channel 130 is connected to the receiving port 111; the area of ​​the cross section of the inner wall of the guide channel 130 perpendicular to the first direction gradually decreases along the first direction, and the guide channel 130 is used to guide the cable tie body 30. The guiding effect of the guide channel 130 on the cable tie body 30 can make it easier for the end of the cable tie body 30 to enter between the clamping member 330 and the traction member 320, so as to make it easier for the staff to operate. On the other hand, the extension length of the cutting slit 230 in the third direction and the reverse direction of the third direction can also be adjusted according to the maximum spacing of the guide channel 130 in the third direction, so that one end of the cable tie body 30 can enter the cutting slit 230 more easily.

[0076] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
