[0002] With the increasing development of the commodity economy, there are more and more places where cable ties are needed to bundle objects, and the application of cable tie guns is becoming more and more widespread. Cable tie guns are special products manufactured and sold specifically for binding and tightening cable ties. They are generally divided into: all-plastic type, all-metal type, and composite type.

[0003] The existing cable tie gun uses a wrench to pull a lever backward, which in turn drives a clamping tooth to grip the cable tie and a drive gear, pulling the drive gear back to a certain position. Once the drive gear is pulled back, it engages a hook pressure block, which presses down on the hook. This causes the cutter to pull up the cutter bar, cutting the cable tie. In this design, because both the pressure block and the hook need to act simultaneously to pull up the cutter bar and drive gear, assembly is inconvenient, and the added number of parts can reduce the cable tie's lifespan.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-3 As shown, a cable tie gun that is easy to assemble includes a housing 1, a wrench 2, a pull rod 3, and a clamping tooth 4. The wrench 2 is movably connected to the housing 1, one end of the pull rod 3 is fixedly connected to the wrench 2, and the other end is fixedly connected to the clamping tooth 4. The pull rod 3 is movably disposed in the housing 1, and the clamping tooth 4 is rotatably connected to one end of the pull rod 3.

[0030] A transmission gear 5 is fixedly connected to the pull rod 3, and a hook 6 is provided on the transmission gear 5. The hook 6 is rotatably connected to the housing 1. A positioning gear 61 is fixedly connected to the hook 6, and the positioning gear 61 is set at an angle on the hook 6.

[0031] A drive shaft 7, a tool holder drive plate 8, a tool shaft 9, and a tool holder 10 are provided on one side of the hook 6. The drive shaft 7, tool holder drive plate 8, tool shaft 9, and tool holder 10 are arranged sequentially. The drive shaft 7 is fixedly connected to the housing 1, and the hook 6 passes through the drive shaft 7. The tool holder drive plate 8 is fixedly connected to the hook 6. One end of the tool holder drive plate 8 is rotatably connected to the drive shaft 7, and the other end is rotatably connected to the tool shaft 9. One end of the tool holder 10 is rotatably connected to the tool shaft 9 and fixedly connected to the tool holder drive plate 8, and the other end is located at the end of the housing 1.

[0032] The end of the tool holder 10 away from the tool shaft 9 is fixedly connected to the blade 12. The blade 12 is located at the end of the housing 1 and is located on one side of the clamping tooth 4.

[0033] The cable tie gun provided in this application, which is easy to assemble, reduces the number of parts, simplifies the assembly process, and lowers the assembly difficulty and time cost by integrating the hook 6 with the transmission gear 5. It eliminates the pressure block in traditional cable tie guns, and directly drives the tool holder transmission plate 8 and the tool holder 10 through the hook 6, reducing the cooperation between parts and lowering the risk of failure. It also reduces friction and wear between parts, and improves the service life of the cable tie gun. The inclined positioning teeth 61 can better cooperate with the cable ties, providing more reliable positioning and clamping force.

[0034] The cable tie gun provided in this application operates as follows: When the lever 2 is pulled, the pull rod 3 drives the clamping teeth 4 to move towards the front end of the housing 1, causing the clamping teeth 4 to engage with the housing 1 to clamp the cable tie. As the pull rod 3 moves, its transmission teeth 5 drive the hook 6 to rotate around the transmission shaft 7. When the hook 6 rotates, it drives the blade transmission plate 8, which in turn drives the blade 10 via the blade shaft 9, causing the blade 12 to move towards the cable tie and cut off the excess. The integrated structure of the transmission teeth 5 and the hook 6 reduces the number of parts and simplifies the assembly process. A single hook 6 simultaneously drives the clamping teeth 4 to clamp and the blade 12 to cut, improving operational continuity. The inclined positioning teeth 61 engage with the cable tie's teeth to prevent slippage, ensuring the transmission of tension and providing more stable tension. The transmission shaft 7 enables multi-component linkage, resulting in high space utilization and suitability for handheld tool design.

[0035] In another embodiment of this utility model, three positioning teeth 61 are provided, all of which are fixedly connected to the hook 6. The three positioning teeth 61 simultaneously engage with the serrated structure of the cable tie, which provides a more balanced clamping force compared to single-point or double-point contact, preventing the cable tie from slipping. The planar contact formed by the three points is more stable, especially under high tension (such as when tightening a thick cable tie), it can disperse stress and avoid tooth slippage or wear caused by local overload.

[0036] In another embodiment of this utility model, the housing 1 is provided with a movable groove 11, and one end of the wrench 2 is movably disposed within the movable groove 11. The movable groove 11 provides a clear sliding track for the wrench 2, ensuring that the wrench 2 moves only in a preset direction (such as back and forth) during the operation, avoiding transmission deviation or jamming caused by shaking. The groove structure restricts one end of the wrench 2 within the housing 1, preventing the wrench 2 from detaching from the housing 1 and ensuring stable force transmission during operation.

[0037] In another embodiment of this utility model, the wrench 2 is provided with a rotating hole 21, which is mounted on the drive shaft 7. The wrench 2 is rotatably connected to the housing 1 via the drive shaft 7. The rotating hole 21 and the drive shaft 7 form a rotating pair, allowing the wrench 2 to rotate only around a fixed axis, ensuring the certainty of the action trajectory and avoiding wobbling or deviation. The position of the drive shaft 7 determines the lever arm length of the wrench 2. Optimized design allows the operator to generate sufficient clamping or cutting torque with less force, improving operating efficiency.

[0038] In another embodiment of this utility model, the pull rod 3 is provided with multiple positioning holes 31, which are evenly arranged on the pull rod 3, and the transmission teeth 5 are installed in the positioning holes 31. By selecting different positions of the positioning holes 31 to install the transmission teeth 5, the engagement depth and angle between the transmission teeth 5 and the cable tie teeth can be adjusted to adapt to standard cable ties with different tooth pitches. The displacement of the positioning holes 31 can change the initial position of the transmission teeth 5, thereby adjusting the preload when the cable tie is tightened, and meeting the tension requirements of different application scenarios (such as cable fixing and packaging bundling).

[0039] In another embodiment of this utility model, a limiting plate 13 is fixedly connected to one end of the pull rod 3 near the clamping teeth 4. The limiting plate 13 is disposed above the clamping teeth 4 and forms a clamping channel with the clamping teeth 4. The width of the channel matches the thickness of the cable tie, ensuring that the cable tie always maintains a straight line movement during the tightening process, avoiding jamming or cutting position deviation caused by offset. The limiting plate 13 covers the upper part of the clamping teeth 4 to prevent the cable tie from tilting upward or bending laterally when under force, especially maintaining the stability of the cable tie under high tension.

[0040] The cable tie gun provided in this application, which is easy to assemble, reduces the number of parts, simplifies the assembly process, and lowers the assembly difficulty and time cost by integrating the hook 6 with the transmission gear 5. It eliminates the pressure block in traditional cable tie guns, and directly drives the tool holder transmission plate 8 and the tool holder 10 through the hook 6, reducing the cooperation between parts and lowering the risk of failure. It also reduces friction and wear between parts, and improves the service life of the cable tie gun. The inclined positioning teeth 61 can better cooperate with the cable ties, providing more reliable positioning and clamping force.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
