[0002] In the existing bundling tool, the bundling tool handle and the bundling tool head are usually integrally connected and cannot be detached, so that the user needs to replace different bundling tools when dealing with different pulling force requirements, which is time-consuming and laborious for the user, and how to improve the universality of the bundling tool has become a technical problem to be solved in the field. SUMMARY

[0003] The utility model solves the technical problem that the existing bundling tool has low universality, and provides a bundling tool head, a bundling tool handle and a bundling tool.

[0004] The utility model solves the above technical problem by the following technical scheme:

[0005] A bundling tool head includes a bundling tightening mechanism, the bundling tool head also includes a tool head shell and a speed reducer, the speed reducer is arranged in the tool head shell and is connected with the transmission shaft of the bundling tightening mechanism, and the surface of the tool head shell has a connecting part that is detachably connected with the bundling tool handle.

[0006] When the tool head shell is connected with the bundling tool handle, the speed reducer is used for transmission connection with the driving motor in the bundling tool handle.

[0007] The bundling tool head is detachably connected with the bundling tool handle through the connecting part arranged on the tool head shell, the bundling tool head is detachable relative to the bundling tool handle, different sizes, specifications and models of bundling tightening mechanisms can be installed on the bundling tool handle by replacing the bundling tool head, different tool heads can be selected according to different bundling, and the application scenarios of a single bundling tool are expanded.

[0008] The speed reducer is also arranged in the bundling tool head and is in transmission connection with the bundling tightening mechanism, so that the speed reducer with different speed reduction ratios is replaced synchronously when the bundling tool head is replaced, and the pulling force difference between bundling tightening mechanisms with different sizes, specifications and models (such as some bundling pulling force that can be stretched to 1800kgf) is met.

[0009] Preferably, the reduction mechanism has a driven tooth corresponding to the driving gear on the shaft of the drive motor, the driven tooth being used to mesh with the driving gear so that the reduction mechanism is connected to the drive motor in a transmission manner.

[0010] By setting a driven tooth on the reduction mechanism to mesh with the driving gear on the shaft of the drive motor, the transmission connection is achieved. Compared with other docking solutions, the connection of positional relationship and transmission relationship is achieved simultaneously through gear meshing, resulting in a more compact docking structure.

[0011] At the same time, the contact area between the gears is relatively larger, which is conducive to the drive motor transmitting power with a larger torque to the cable tie fastening tool head.

[0012] Preferably, the reduction mechanism is connected to the drive motor via a plug-in engagement, and the plug-in engagement direction of the reduction mechanism is consistent with the detachable connection direction of the cable tie fastening tool head relative to the cable tie fastening tool handle.

[0013] The cable tie fastening tool head is directly connected to the cable tie fastening tool handle. Movement in one direction can achieve docking between the cable tie fastening tool head and the cable tie fastening tool handle in terms of both position and transmission, enabling quick replacement of the tool head relative to the main body.

[0014] Preferably, the connecting portion includes an annular recess formed on the surface of the tool head housing, the annular recess being for inserting an annular protrusion on the cable tie fastening tool handle to achieve a detachable connection relative to the cable tie fastening tool handle.

[0015] The tool head has a circular recessed part for inserting a circular protrusion on the handle to secure the cable tie, thereby positioning the tool head relative to the handle and improving the connection rigidity between the two, which is beneficial for the transmission of force.

[0016] Preferably, the connecting portion further includes a plurality of connecting holes formed on the periphery of the annular recess, the plurality of connecting holes being evenly arranged around the axis of the annular recess, the connecting holes being used for fasteners to pass through to achieve a detachable connection relative to the handle of the cable tie fastening tool.

[0017] The tool head is further provided with a connection hole for fasteners to pass through and fix to the cable tie fastening tool handle, thereby improving the reliability of the connection between the cable tie fastening tool head and the cable tie fastening tool handle.

[0018] These connecting holes are evenly arranged around the central axis of the annular recess, allowing the tool head to be fixed to the cable tie fastening tool handle at multiple positions in the direction of rotation of the axis, and the orientation of the tool head can be adjusted to meet different cable tie fastening needs.

[0019] Preferably, the cable tie fastening tool head further includes a cable tie cutting mechanism, which includes an upper cutter, a lower cutter, and a handle;

[0020] The upper cutter is fixed to the tool head housing;

[0021] And / or, the lower cutter is rotatably connected to the tool head housing, and the outer surface of the lower cutter abuts against the upper cutter;

[0022] And / or, the handle is L-shaped.

[0023] The upper and lower cutters are coaxially aligned to position the upper cutter while allowing it to rotate. The lower cutter provides excellent support for the upper cutter when the cable tie is tightened, reducing stress.

[0024] The handle adopts an L-shaped design, changing from a grip to a push-pull method. This increases the lever arm and enhances the explosive force of the push.

[0025] Preferably, the surface of the tool head housing has multiple mounting ports for each component of the deceleration mechanism to enter and exit the tool head housing. The cable tie fastening tool head also includes multiple cover plates, which are detachably connected to the tool head housing and respectively close each of the mounting ports.

[0026] To address the issue that while split-type tool head housings are easy to install with a speed reduction mechanism, their low structural precision leads to poor transmission performance and an inability to transmit large forces.

[0027] To ensure the integrity of the tool head housing, multiple mounting ports are created on the single-piece tool head housing. Each component of the reduction mechanism is installed into the tool head housing through its respective port, and these ports are then closed with a cover plate. This allows the reduction mechanism to be housed within the single-piece tool head housing, improving the installation accuracy of the reduction mechanism relative to the tool head housing and enhancing transmission efficiency. Furthermore, the single-piece tool head housing has greater structural strength than a split-type tool head housing, enabling more reliable transmission of larger forces.

[0028] Preferably, the reduction mechanism includes a worm gear, a worm shaft, and a planetary reducer connected in sequence, and the worm gear, the worm shaft, and the planetary reducer are respectively disposed in the tool head housing through different mounting ports.

[0029] This utility model also provides a cable tie fastening tool handle, which is used to connect with the cable tie fastening tool head as described above.

[0030] This utility model also provides a cable tie fastening tool, which includes:

[0031] Cable tie fastening tool head as described above;

[0032] A cable tie fastening tool handle, the cable tie fastening tool handle being used to mate with the cable tie fastening tool head, the cable tie fastening tool handle further comprising:

[0033] The scanning module is used to obtain the target tensile force value of the cable tie from the barcode by scanning the code;

[0034] A torque detection module is provided, wherein the drive motor is connected to the cable tie tightening mechanism of the cable tie fastening tool head via the torque detection module, and the torque detection module is used to detect the torque output value of the drive motor.

[0035] Both the scanning module and the torque detection module are connected to the control module of the drive motor via signal connection.

[0036] This cable tie tightening tool is equipped with a scanning module and a torque detection module that are connected to the control module of the drive motor. The scanning module obtains the target tension value for tightening the cable tie by scanning a code, while the torque detection module detects the torque output value of the drive motor. The scanning and torque detection modules are connected to the control module of the drive motor, allowing the control module to adjust the motor's output torque based on the measured torque output value. This ensures the motor's output torque matches the target tension value required for tightening the cable tie, effectively tightening it according to actual needs. This cable tie tightening tool is easy to operate and requires no manual input of the target tension value.

[0037] The significant advantages of this invention are as follows: The cable tie fastening tool head, by having a detachable connection on its outer shell to the cable tie fastening tool handle, allows for easy assembly and disassembly of the tool head relative to the handle. By replacing the tool head, different sizes, specifications, and models of cable tie tightening mechanisms can be installed on the handle. Different tool heads can be selected for different cable ties, expanding the applicability of a single cable tie fastening tool. Furthermore, the reduction mechanism is also integrated within the tool head, maintaining a transmission connection with the tightening mechanism. This allows for simultaneous replacement of different reduction ratios of the reduction mechanism when changing the tool head, thus accommodating the varying tensile strengths of different sizes, specifications, and models of cable tie tightening mechanisms (some cable ties can stretch up to 1800 kgf).

[0076] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0077] like Figures 1-7 As shown, this embodiment provides a cable tie tightening tool head 10, which includes a cable tie tightening mechanism 100. Specifically, the cable tie tightening mechanism 100 is connected to the end of the cable tie via a cross groove 111 on a tightening shaft 110, and rotates under the drive of a drive motor to tighten the cable tie. The cable tie tightening tool head 10 also includes a tool head housing 200 and a reduction mechanism 300. The reduction mechanism 300 is disposed inside the tool head housing 200 and connected to the drive shaft of the cable tie tightening mechanism 100. The surface of the tool head housing 200 has a connecting portion 400 that is detachably connected to the cable tie tightening tool handle 20. When the tool head housing 200 is connected to the cable tie tightening tool handle 20, the reduction mechanism 300 is used for transmission connection with the drive motor (not shown in the figure) inside the cable tie tightening tool handle 20.

[0078] The cable tie fastening tool head 10 is detachable from the cable tie fastening tool handle 20 by a connecting part 400 provided on the tool head housing 200 and detachable from the cable tie fastening tool handle 20. By replacing the cable tie fastening tool head 10, different sizes, specifications and models of cable tie tightening mechanisms 100 can be installed on the cable tie fastening tool handle 20. Different tool heads can be selected according to different cable ties, thus expanding the applicable scenarios of a single cable tie fastening tool 1.

[0079] The deceleration mechanism 300 is also installed inside the cable tie fastening tool head 10 and is connected to the cable tie tightening mechanism 100 for transmission. This allows the deceleration mechanism 300 with different reduction ratios to be replaced simultaneously when the cable tie fastening tool head 10 is replaced, thereby meeting the tension differences between cable tie tightening mechanisms 100 of different sizes, specifications and models (some cable ties can be stretched to 1800 kgf).

[0080] The reduction mechanism 300 has a driven tooth 340 corresponding to the driving gear 24 on the shaft 21 of the drive motor. The driven tooth 340 is used to mesh with the driving gear 24 so that the reduction mechanism 300 is connected to the drive motor for transmission.

[0081] The transmission connection is achieved by setting a driven tooth 340 on the reduction mechanism 300 to mesh with the driving gear 24 on the shaft 21 of the drive motor. Compared with other docking solutions, the gear meshing method achieves both positional and transmission connections simultaneously, resulting in a more compact docking structure. At the same time, the contact area between the gears is relatively larger, which is beneficial for transmitting the larger torque of the drive motor to the cable tie fastening tool head 10.

[0082] like Figure 10 As shown, the reduction mechanism 300 is connected to the drive motor via a plug-in engagement method. The plug-in engagement direction of the reduction mechanism 300 is the same as the detachable connection direction of the cable tie fastening tool head 10 relative to the cable tie fastening tool handle 20 (e.g., Figure 10 (As shown in the connection direction B).

[0083] The cable tie fastening tool head 10 is directly connected to the cable tie fastening tool handle 20. Movement in one direction can realize the docking of the cable tie fastening tool head 10 and the cable tie fastening tool handle 20 in terms of both position and transmission relationship, so as to realize the quick replacement of the tool head relative to the handle part.

[0084] Combination Figure 1 , Figure 8 , Figure 9 and Figure 10The connecting portion 400 includes an annular recess 410 formed on the surface of the tool head housing 200, the annular recess 410 being used to insert an annular protrusion 22 on the cable tie fastening tool handle 20 to achieve a detachable connection relative to the cable tie fastening tool handle 20.

[0085] The connecting portion 400 of the tool head is provided with an annular recess 410 for the annular protrusion 22 on the tool handle 20 to be inserted into, thereby positioning the tool head relative to the handle portion, improving the connection rigidity between the two and facilitating the transmission of force. In other embodiments, the connecting portion 400 may also adopt other forms of connection, such as using other shapes of concave-convex mating parts for insertion.

[0086] like Figure 1 As shown, the connecting portion 400 also includes four connecting holes 420 formed on the periphery of the annular recess 410. The four connecting holes 420 are evenly arranged around the axis of the annular recess 410 (not shown in the figure). The connecting holes 420 are used for fasteners 430 to pass through to achieve a detachable connection with respect to the cable tie fastening tool handle 20.

[0087] The connecting portion 400 of the cable tie fastening tool head 10 is further provided with a connecting hole 420 for fasteners 430 to pass through for fixing to the cable tie fastening tool handle 20, thereby improving the reliability of the connection between the cable tie fastening tool head 10 and the cable tie fastening tool handle 20.

[0088] The connecting holes 420 are evenly arranged around the axis of the annular recess 410, so that the cable tie fastening tool head 10 can be fixed to the cable tie fastening tool handle 20 at multiple positions in the rotation direction of the axis, and the orientation of the tool head can be adjusted to meet different cable tie fastening needs.

[0089] like Figures 1-7 As shown, the cable tie fastening tool head 10 also includes a cable tie cutting mechanism 500, which includes an upper cutter 510, a lower cutter 520, and a handle 530. The upper cutter 510 is fixed to the tool head housing 200. The lower cutter 520 is rotatably connected to the tool head housing 200, and the outer surface of the lower cutter 520 abuts against the upper cutter 510. The handle 530 is L-shaped.

[0090] In this embodiment, the upper cutter 510 and the lower cutter 520 are coaxially coupled to position the upper cutter 510 and retain its rotational function. The lower cutter 520 provides good support for the upper cutter 510 when the cable tie is tightened, reducing stress. Specifically, in this embodiment, the upper cutter 510 is clip-shaped, divided into an upper half and a lower half, and the lower cutter 520 is cylindrical and inserted into the upper cutter 510 for coaxial coupling.

[0091] Furthermore, the handle 530 adopts an L-shaped design, changing the previous grip handle 530 to a push handle 530 method, which can increase the lever arm and thus improve the explosive force of the push.

[0092] like Figures 2-5 As shown, the surface of the tool head housing 200 has three mounting ports 600 for each component of the reduction mechanism 300 to enter and exit the tool head housing 200. The cable tie fastening tool head 10 also includes three cover plates 700, which are detachably connected to the tool head housing 200 and respectively enclose the mounting ports 600 of the planetary reducer 330, worm gear 310, and worm 320.

[0093] To ensure the integrity of the tool head housing 200, this design incorporates three mounting openings 600 on the single-unit tool head housing 200. Each component of the reduction mechanism 300 is installed into the tool head housing 200 through its respective mounting opening 600, and then closed by a cover plate 700. This allows the reduction mechanism 300 to be housed within the single-unit tool head housing 200, improving the installation accuracy of the reduction mechanism 300 relative to the tool head housing 200 and enhancing transmission efficiency. Furthermore, the single-unit tool head housing 200 has greater structural strength than the split-unit tool head housing 200, enabling more reliable transmission of larger forces. This design solves the problem that while a split-unit tool head housing 200 allows for easy installation of the reduction mechanism 300 internally, its lower structural precision can lead to poor transmission performance and an inability to transmit larger forces.

[0094] like Figures 1-7 As shown, the reduction mechanism 300 includes a worm gear 310, a worm 320 and a planetary reducer 330 connected in sequence. The worm gear 310, the worm 320 and the planetary reducer 330 are respectively installed in the tool head housing 200 through different mounting ports 600.

[0095] like Figures 8-10 As shown, this utility model also provides a cable tie fastening tool handle 20, which is used to connect with the cable tie fastening tool head 10 as described above.

[0096] like Figure 10As shown, this utility model also provides a cable tie fastening tool 1, which includes: a cable tie fastening tool head 10 as described above; a cable tie fastening tool handle 20, which is used to connect with the cable tie fastening tool head 10, and the cable tie fastening tool handle 20 further includes: a scanning module 23, which is used to obtain the target tension value of tightening the cable tie from the barcode by scanning; a torque detection module (not shown in the figure), in which a drive motor is connected to the cable tie tightening mechanism 100 of the cable tie fastening tool head 10 through the torque detection module, and the torque detection module is used to detect the torque output value of the drive motor; both the scanning module 23 and the torque detection module are signal connected to the control module (not shown in the figure) of the drive motor.

[0097] The cable tie tightening tool 1 is equipped with a scanning module 23 and a torque detection module that are signal-connected to the control module of the drive motor. The scanning module 23 obtains the target tension value for tightening the cable tie by scanning a code. The torque detection module detects the torque output value of the drive motor. The scanning module 23 and the torque detection module are signal-connected to the control module of the drive motor, allowing the control module to adjust the output torque of the drive motor based on the torque output value measured by the torque detection module. This ensures that the output torque of the drive motor matches the target tension value required for tightening the cable tie, effectively tightening the cable tie according to actual needs. This cable tie tightening tool is easy to operate and does not require manual input of the required target tension value. The details of how the scanning module 23, the torque detection module, and the control module of the drive motor are prior art and will not be elaborated upon here.
