However, existing cable tie fastening tools still suffer from numerous technical shortcomings. Specifically, users need to manually control the tool's operation to regulate the tightness of the cable ties, or manually input the desired tightness level to precisely tighten the ties. This fails to meet the demands of modern industry for efficient, precise, and intelligent operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of existing cable tie fastening tools in that they cannot meet the requirements of efficient and precise cable tie fastening, and to provide a cable tie fastening tool.

[0008] Both the scanning module and the torque detection module are connected to the control module of the drive motor via signal connection.

[0009] 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.

[0012] Preferably, the cable tie fastening tool further includes an interactive input module and / or an interactive output module, the interactive input module and / or the interactive output module being disposed on the surface of the tool housing and located behind the scanning window.

[0013] By incorporating an interactive input or output module on the surface of the tool housing, the level of interaction between the user and the cable tie fastening tool is enhanced.

[0016] Preferably, the angle detection module is mounted on the drive shaft of the drive motor.

[0017] Since the shaft of the cable tie tightening mechanism is a wear part that needs to be replaced frequently, this solution indirectly obtains the rotation angle value of the cable tie tightening mechanism's shaft by setting the angle detection module on the drive shaft of the drive motor, thereby avoiding any impact on the disassembly and assembly of the cable tie tightening mechanism's shaft due to the setting of the angle detection module.

[0020] By enabling the drive motor to rotate the shaft to zero position based on the angle detection module, the shaft can be driven to the zero position before the cable tie fastening tool is used again, making it easier for users to install cable ties when using the cable tie fastening tool again and simplifying the use process.

[0021] Preferably, the operation process of the control module for the drive motor includes:

[0022] Calculate the target torque value of the drive motor based on the target tension value, compare the difference between the target torque value and the torque output value, and adjust the output torque of the drive motor to match the target torque value based on the difference;

[0023] During the adjustment of the output torque of the drive motor, the current rotational speed of the shaft of the cable tie tightening mechanism is calculated based on the rotational angle value, and the drive motor is controlled to decelerate based on the degree of reduction of the difference.

[0024] Preferably, the cable tie fastening tool further includes a data transmission module, which is signal-connected to the torque detection module and / or the control module of the drive motor, and is used to send the torque output value of the torque detection module to the back-end server wirelessly.

[0027] The scanning module is also used to obtain one or more of the specifications, quantity, and name of the cable ties from the barcode by scanning, and to send one or more of the specifications, quantity, and name of the cable ties to the backend server through the data transmission module.

[0028] The scanning module inside the cable tie fastening tool scans the barcode to obtain information such as the cable tie's specifications, quantity, and name. This data is then sent to the backend server via the data transmission module within the tool, enabling the server to monitor and record the cable tie's usage and facilitate timely replenishment of inventory.

[0029] Preferably, the cable tie fastening tool further includes an interactive input module, which is signal-connected to the control module of the drive motor.

[0033] Preferably, the control module of the drive motor is integrated into the control board of the cable tie fastening tool.

[0034] This structural design improves the integration of cable tie fastening tools.

[0036] The tool head housing and the handle housing are detachably connected. When the tool head housing is connected to the handle housing, the reduction mechanism is connected to the drive motor.

[0037] This cable tie fastening tool allows for the detachment of the tool head and handle. By changing 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 according to different cable ties, expanding the applicable scenarios of a single cable tie fastening tool.

[0038] The deceleration mechanism is also located in the tool head of the cable tie fastening tool and is connected to the cable tie tightening mechanism. This allows for the simultaneous replacement of different deceleration mechanisms with different reduction ratios when changing the cable tie fastening tool head, thereby meeting the tension differences between different sizes, specifications, and models of cable tie tightening mechanisms (some cable ties can be stretched to 1800 kgf).

[0039] Meanwhile, the drive motor, torque detection module, and scanning module are located inside the handle of the cable tie fastening tool, so that torque detection and tension input functions can be maintained even when the tool head is changed.

[0040] Preferably, the operation process of the control module for the drive motor includes:

[0041] The target torque value of the drive motor is calculated based on the target tension value. The difference between the target torque value and the torque output value is compared, and the output torque of the drive motor is adjusted based on the difference to match the target torque value.

[0042] The control module calculates the target torque value of the drive motor based on the target tension value, and then adjusts the output torque of the drive motor by comparing the difference between the target torque value and the torque output value, so that the tension corresponding to the output torque of the drive motor can match the target tension value obtained by scanning the code, thereby improving the accuracy of cable tie locking.

[0043] A control method for a cable tie fastening tool, used to correct the output torque of the cable tie fastening tool as described above, the control method comprising:

[0044] The control module of the drive motor of the cable tie fastening tool controls the operation of the drive motor by a preset output torque value;

[0055] The control module of the drive motor controls the torque of the drive motor based on the difference between the target torque value and the torque output value, wherein the smaller the difference, the smaller the increase in the output torque of the drive motor.

[0056] This closed-loop control method enables precise control of the output torque of the drive motor, allowing the cable tie fastening tool to output precise torque for different cable ties (based on different target tension values ​​input), thus meeting the precise tightening requirements of different cable ties.

[0057] Preferably, the control method further includes:

[0058] The control module of the drive motor also controls the speed of the drive motor based on the difference between the target torque value and the torque output value, wherein the smaller the difference, the smaller the speed of the drive motor.

[0059] As the output torque of the cable tie fastening tool gradually approaches the target torque, the speed of the drive motor should be kept as low as possible so that the drive motor can stop in time when the torque is reached, thus avoiding over-rotation.

[0060] Preferably, the control module of the drive motor uses a field-oriented control method to control the drive motor.

[0061] The motor control program adopts the field-oriented control (FOC) method, which achieves the effect of separate control of torque and speed, and also provides technical support for high-precision and high-efficiency control of cable tie fastening tools.

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. Attached Figure Description

[0085] 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.

[0086] Example 1

[0087] like Figure 1 As shown, this utility model provides a cable tie fastening tool 100, which includes a tool housing 1, a cable tie tightening mechanism 2, a scanning module 5, a drive motor 4, and a torque detection module 6. The cable tie tightening mechanism 2 is disposed on the front surface of the tool housing 1, the scanning module 5 is disposed on the top of the tool housing 1, and the drive motor 4 and the torque detection module 6 are disposed inside the tool housing 1.

[0088] like Figure 1 and Figure 2 As shown, the cable tie tightening mechanism 2 connects to the end of the cable tie via a cross groove on its rotating shaft 21. Driven by the drive motor 4, it rotates, tightening the cable tie. The scanning module 5 obtains the target tension value for tightening the cable tie from the barcode by scanning. The torque detection module 6 is located on the transmission path between the drive motor 4 and the cable tie tightening mechanism 2. The torque detection module 6 detects the torque output value of the drive motor 4. By connecting the scanning module 5 and the torque detection module 6 to the control module 41 of the drive motor 4, the target tension value for tightening the cable tie obtained by the scanning module 5 by scanning the barcode and the torque output value detected by the torque detection module 6 can be transmitted to the control module 41. This allows the control module 41 to control the output torque of the drive motor 4 based on the target tension value obtained by scanning the barcode and the actual torque output value, ensuring that the tool tightens the cable tie to the required degree.

[0089] The cable tie fastening tool 100 is equipped with a scanning module 5 and a torque detection module 6, which are signal-connected to the control module 41 of the drive motor 4. The scanning module 5 obtains the target tension value for tightening the cable tie by scanning a barcode. The torque detection module 6 detects the torque output value of the drive motor 4. The scanning module 5 and the torque detection module 6 are signal-connected to the control module 41 of the drive motor 4, enabling the control module 41 of the drive motor 4 to adjust the output torque of the motor based on the measured torque output value, so that the output torque of the motor matches the target tension value required to tighten the cable tie, and effectively tightens the cable tie according to actual needs. The cable tie fastening tool 100 is easy to operate and does not require manual input of the required target tension value. The specific value of the target tension value of the cable tie can be determined based on multiple factors, including the preferred tension range of the cable tie, the actual needs of the user (customer), etc. Therefore, by inputting the tension value information into the barcode, the cable tie fastening tool 100 can obtain it by scanning the barcode, which can speed up the input process and reduce the input difficulty. Another advantage is that it allows for the customization of actual tensile strength values ​​based on the user's (customer's) actual needs, and avoids data transmission errors caused by human factors during the process of transmitting data via barcode information.

[0090] In this embodiment, the cable tie fastening tool 100 further includes a reduction mechanism 3, and the drive motor 4 is connected to the cable tie tightening mechanism 2 via the reduction mechanism 3. A torque detection module 6 is located at the transmission connection between the drive motor 4 and the reduction mechanism 3 to directly detect the output torque of the drive motor 4. The torque detection module 6 is implemented by placing a torque sensor between the drive motor 4 and the reduction mechanism 3.

[0091] The linear relationship between the tension and torque values ​​is established. This linear relationship can be input into the control module 41 of the drive motor 4 during the tool manufacturing process. After acquiring the target tension value from the scanning module 5, the control module 41 can calculate the target torque value of the drive motor 4 based on the target tension value. The output torque of the drive motor 4 is then controlled based on the target torque value and the torque output value measured by the torque detection module 6. Of course, the linear relationship between tension and torque values ​​is existing technology and can be obtained through formula calculation or product calibration, which will not be elaborated here. Furthermore, in this embodiment, the control module 41 of the drive motor 4 converts the target tension value into a torque value after acquiring the target tension value and performs closed-loop control of the drive motor 4 based on torque. The closed-loop control scheme and principle based on torque for the motor can be found in existing technologies and will not be elaborated here.

[0092] Specifically, in this embodiment, the operation of the control module 41 of the drive motor 4 includes the following steps: First, the control module 41 calculates the target torque value of the drive motor 4 based on the target tension value obtained by the scanning module 5. Then, it compares the difference between the target torque value and the torque output value, and adjusts the output torque of the drive motor 4 based on this difference, so that the output torque of the drive motor 4 matches the target torque value, improving the accuracy of the cable tie tightening and ensuring that the tightness of the cable tie meets the requirements.

[0093] In this embodiment, as Figure 1 As shown, the scanning window 51 of the scanning module 5 is located at the top center of the tool housing 1, and the scanning window 51 faces forward, so that the user can align the scanning window 51 with the barcode to input the target tension value while holding the tool housing 1. The barcode containing the target tension value information for tightening the cable tie, scanned by the scanning module 5, can be a QR code, a traditional barcode, or any other barcode format. These barcodes can be printed or affixed to the outer packaging of the cable tie product or other easily scannable locations, allowing the user to quickly input the target tension value into the cable tie fastening tool 100 by scanning the barcode with the scanning module 5 when the cable tie is needed. Based on the torque detection module 6, the drive motor 4 is subjected to closed-loop feedback control to effectively tighten the cable tie according to actual needs. Furthermore, the information stored in the barcode scanned by the cable tie fastening tool 100 can include various information such as the cable tie's specifications, quantity, and name. This allows the cable tie fastening tool 100 to obtain more information than just the target tensile force value during a single scan, enhancing its digital capabilities and enabling it to perform more functions based on the more information obtained through scanning. Preferably, the information within the barcode can be encrypted, ensuring that only the scanning module 5 of the cable tie fastening tool 100 can compile and extract the information, thus protecting the cable tie information and tightening parameters.

[0094] For example, the cable tie fastening tool 100 can also be equipped with a data transmission module 8. The data transmission module 8 is connected to the control module 41 of the drive motor 4. After obtaining various information, including the specifications, quantity and name of the cable tie, by scanning the code, the data transmission module 8 sends the various information of the cable tie to the back-end server wirelessly, so that the back-end server can monitor and record the usage of the cable ties, which is convenient for timely replenishment of inventory.

[0095] Specifically, after scanning the QR code on the outer packaging of the cable ties using the cable tie fastening tool 100, users obtain information about the cable tie's specifications, quantity, and name. This information is then uploaded to the backend server after scanning. The backend server records the scanned specifications, quantity, and name of the cable ties and deducts this information from the corresponding warehouse data. This allows for real-time monitoring of cable tie usage and timely inventory updates. Compared to the current method of manually recording, reporting, and adjusting inventory after cable tie usage, this method effectively simplifies the difficulty of backend monitoring.

[0096] In addition, in this embodiment, the data transmission module 8 is also connected to the torque detection module 6 by signal, so that the data can be transmitted wirelessly to the back-end server, enabling the back-end server to monitor and record the torque of the cable ties, which facilitates torque inspection and construction management.

[0097] In this embodiment, as Figure 2 As shown, the cable tie fastening tool 100 also includes an angle detection module 7. The angle detection module 7 is used to detect the rotation angle value of the rotating shaft 21 of the cable tie tightening mechanism 2. The angle detection module 7 is signal-connected to the control module 41 of the drive motor 4. By setting the angle detection module 7 to detect the rotation angle value of the rotating shaft 21 of the cable tie tightening mechanism 2, and by signal-connecting the angle detection module 7 to the control module 41 of the drive motor 4, the control module 41 of the drive motor 4 can adjust the rotation angle of the motor based on the measured rotation angle value.

[0098] Specifically, in this embodiment, the angle detection module 7 is mounted on the drive shaft of the drive motor 4. This is because the rotating shaft 21 of the cable tie tightening mechanism 2 is a consumable part that needs frequent replacement. Therefore, in this solution, by mounting the angle detection module 7 on the drive shaft of the drive motor 4, the rotation angle of the rotating shaft 21 of the cable tie tightening mechanism 2 is indirectly obtained by the angle detection module 7 detecting the rotation angle of the drive shaft of the drive motor 4. This avoids the angle detection module 7 affecting the disassembly and assembly of the rotating shaft 21 of the cable tie tightening mechanism 2. In this embodiment, the angle detection module 7 specifically uses an encoder to achieve accurate angle detection.

[0099] Based on the angle detection module 7, the operation of the control module 41 of the drive motor 4 further includes: adjusting the output torque of the drive motor 4 based on the difference between the target torque value and the torque output value, so that the output torque of the drive motor 4 gradually matches the target torque value; the control module 41 of the drive motor 4 also calculates the current rotational speed of the shaft 21 of the cable tie tightening mechanism 2 based on the rotational angle value measured by the angle detection module 7, and controls the drive motor 4 to decelerate based on the degree of reduction in the difference in output torque. As the output torque of the cable tie fastening tool 100 gradually approaches the target torque, the speed of the drive motor 4 is controlled so that the drive motor 4 can stop in time when the torque reaches the target, avoiding over-rotation.

[0100] For example, if the target torque value calculated from the target tensile force for a certain style and model of cable tie is 10 nm, then when the output torque of the drive motor 4 is 5 nm, the current rotational speed of the shaft 21 of the cable tie tightening mechanism 2 is calculated based on the rotational angle value measured by the angle detection module 7, and the drive motor 4 is controlled to decelerate. Furthermore, when the output torque of the drive motor 4 is 8 nm, the drive motor 4 is further controlled to decelerate, so that when the output torque of the drive motor 4 is 10 nm, the drive motor 4 can be controlled to stop quickly.

[0101] Under this control scheme, the control module 41 preferably adopts the field-oriented control (FOC) method to control the drive motor 4. The field-oriented control method achieves the effect of separate control of torque and speed, and also provides technical support for the high-precision and high-efficiency control of the cable tie fastening tool 100.

[0102] Furthermore, for the cable tie fastening tool 100, during the tightening process driven by the rotating shaft 21, the cable tie continuously wraps and accumulates on the outer surface of the rotating shaft 21. Therefore, the torque transmitted from the rotating shaft 21 to the cable tie increases with the winding of the cable tie, resulting in an increase in the lever arm. Even with a constant torque, the torque output to the cable tie will increase due to the winding of the cable tie on the surface of the rotating shaft 21. Therefore, by using the angle detection module 7, the angle of the rotating shaft 21 can be measured, and the degree of winding of the cable tie on the rotating shaft 21 can be further calculated. This allows for the calculation of the increase in the lever arm, enabling control of the output torque to prevent the torque acting on the cable tie from increasing due to the continuous winding of the cable tie on the surface of the rotating shaft 21. The relationship between the measured rotation angle value, the degree of winding of the cable tie on the surface of the rotating shaft 21, the increase in the lever arm, and the increase in the final output torque can be established through a linear relationship for conversion. The specific calculation formula will not be elaborated here.

[0103] like Figure 1 As shown, the cable tie fastening tool 100 also includes an interactive input module 91 and an interactive output module 92. Both the interactive input module 91 and the interactive output module 92 are disposed on the surface of the tool housing 1 and located behind the scanning window 51. By providing the interactive input module 91 and the interactive output module 92 on the surface of the tool housing 1, the level of interaction between the user and the cable tie fastening tool 100 is improved. Positioning the interactive input module 91 and the interactive output module 92 behind the scanning window 51 facilitates the user's simultaneous input or output of information to the cable tie fastening tool 100 while scanning the barcode. In other embodiments, depending on actual needs, only the interactive input module 91 may be provided on the cable tie fastening tool 100 to output information, or only the interactive output module 92 may be provided to facilitate the user's input of information to the tool.

[0104] Specifically, in this embodiment, as Figure 3 As shown, the interactive output module 92 is a touchscreen. The interactive output module 92 is signal-connected to the torque detection module 6, enabling it to output the torque value of the cable tie fastening tool 100 via image display, allowing the user to easily understand the torque or tension of the cable tie fastening tool 100. In other embodiments, the interactive output module 92 can also be a speaker or indicator light, providing sound or light feedback to the user regarding the torque status. Furthermore, since the tension and torque values ​​of the cable ties can be converted using a linear relationship, in other embodiments, the actual tension value can also be directly output. Tension values ​​are easier for users to understand than torque values, providing a more intuitive feedback on the cable tie tightening status.

[0105] In addition, such as Figure 4 As shown, the interactive output module 92 can also be connected to the angle detection module 7 via a signal, so that the interactive output module 92 can display the rotation angle of the rotating shaft 21 of the cable tie tightening mechanism 2 through an image display method, so as to provide the user with more information and facilitate the user to make quick and accurate usage judgments based on the actual situation.

[0106] In this embodiment, as Figure 5 As shown, the interactive input module 91 is signal-connected to the control module 41 of the drive motor 4. The interactive input module 91 allows users to input information and precisely control the operation of the control module 41. The interactive input module 91 can be implemented using any module that allows users to input information into the tool, such as buttons, microphones, or data input ports. For example, in this embodiment, the interactive input module 91 includes buttons on the surface of the tool housing 1 and a touchscreen input function on the display screen. Users can perform a series of tasks such as scanning codes and tightening cable ties by operating the buttons and the touchscreen.

[0107] This utility model further provides a control method for the above-mentioned cable tie fastening tool 100, so as to achieve precise tightening of the cable tie or correction of the output tension.

[0108] In this embodiment, based on the touchscreen and button configuration, the tool has a UI module that can be displayed via the touchscreen. This UI module has four buttons on either side of the touchscreen for navigating the UI menu and inputting relevant parameters.

[0109] The UI module features three LEDs above the touchscreen. These LEDs illuminate to indicate whether the operation was successful or failed. For example, when tightening cable ties, if the tension is less than 10% of the target tension, the LEDs will light up red; otherwise, they will light up green.

[0110] The main interface of this UI module also displays the torque and tension during the tightening process in real time, making it easy for operators to understand the results. In addition, through button operation, the tension curve can also be displayed on the touch screen, showing the tension change curve throughout the entire tightening process.

[0111] like Figure 6 As shown, this utility model provides a control method for a cable tie fastening tool 100, which is used to control the cable tie fastening tool 100 to tighten the cable ties. The control method for the cable tie fastening tool 100 includes:

[0112] S11, the control module 41 of the drive motor 4 calculates the target torque value of the drive motor 4 based on the target tension value.

[0113] S12, the control module 41 of the drive motor 4 controls the torque of the drive motor 4 based on the difference between the target torque value and the torque output value. Wherein, the smaller the difference, the smaller the increase in the output torque of the drive motor 4.

[0114] This closed-loop control method enables precise control of the output torque of the drive motor 4, allowing the cable tie fastening tool 100 to output precise torque for different cable ties (based on different target tension values ​​input), thus meeting the precise tightening requirements of different cable ties.

[0115] In this embodiment, since an angle detection module 7 is also provided to detect the rotation angle value of the rotating shaft 21, the control module 41 of the drive motor 4 can calculate the rotation speed of the rotating shaft 21 through the rotation angle value, thereby achieving precise control of the rotation speed of the drive motor 4. Therefore, the control method of the cable tie fastening tool 100 further includes:

[0116] S13, the control module 41 of the drive motor 4 also controls the speed of the drive motor 4 based on the difference between the target torque value and the torque output value, wherein the smaller the difference, the smaller the speed of the drive motor 4.

[0117] As the output torque of the cable tie fastening tool 100 gradually approaches the target torque, the speed of the drive motor 4 is controlled to be smaller so that the drive motor 4 can stop in time when the torque reaches the target, thus avoiding over-rotation.

[0118] In the control method described above, steps S12 and S13 can be performed simultaneously.

[0119] Specifically, in this embodiment, the control module 41 of the drive motor 4 adopts the field-oriented control (FOC) method to control the drive motor 4, which realizes the effect of separate control of torque and speed, and also provides technical support for the high-precision and high-efficiency control of the cable tie fastening tool 100.

[0120] In addition, such as Figure 7 As shown, this utility model provides another control method for the cable tie fastening tool 100, which uses an internal torque detection module 6 to correct the output torque of the cable tie fastening tool 100. The control method for the cable tie fastening tool 100 includes:

[0121] S21, the control module 41 of the drive motor 4 controls the operation of the drive motor 4 by a preset output torque value.

[0122] S22. The first actual output torque value of the cable tie fastening tool 100 is detected by the torque detection module 6, and the first actual output torque value is transmitted to the control module 41 of the drive motor 4.

[0123] S23, the control module 41 of the drive motor 4 adjusts the torque output parameters of the drive motor 4 based on the difference between the first actual output torque value and the preset output torque value.

[0124] This control method adjusts the torque output parameters of the drive motor 4 by measuring the actual output torque value through the torque detection module 6, thereby achieving precise control.

[0125] In addition, such as Figure 8 As shown, this utility model provides another control method for the cable tie fastening tool 100, which uses an external tension gauge or other tension detection device to correct the output torque of the cable tie fastening tool 100. The control method for the cable tie fastening tool 100 includes:

[0126] S31, the control module 41 of the drive motor 4 controls the operation of the drive motor 4 by a preset output torque value.

[0127] S32. The actual output tension value of the cable tie fastening tool 100 is detected by an external tension gauge, and the actual output tension value is transmitted to the control module 41 of the drive motor 4.

[0128] S33, the control module 41 of the drive motor 4 calculates the second actual output torque value based on the actual output tension value, and adjusts the torque output parameters of the drive motor 4 based on the difference between the second actual output torque value and the preset output torque value.

[0129] This control method calculates a second actual output torque value based on the actual output tension value measured by an external tension gauge, and then adjusts the torque output parameters of the drive motor 4 based on the second actual output torque value to achieve calibration and precise control. The actual output tension value measured by the external tension gauge can be obtained by scanning a barcode containing the actual output tension value information displayed on the tension gauge's display interface using the scanning module 5 of the cable tie fastening tool 100, or by displaying the actual output tension value data on the tension gauge's display interface and having the user input the measured tension data into the tool through the interactive output module 92 of the cable tie fastening tool 100.

[0130] Example 2

[0131] This embodiment also provides a cable tie fastening tool 100, whose structure is largely the same as that of the cable tie fastening tool 100 provided in Embodiment 1, with the main difference being that... Figure 8 As shown, in this embodiment, the control module 41 of the drive motor 4 is integrated into the control board 101 of the cable tie fastening tool 100. This structural arrangement can improve the system integration of the cable tie fastening tool 100 and enhance its operational reliability.

[0132] Example 3

[0133] This embodiment provides a cable tie fastening tool 100, the structure of which is roughly the same as that of the cable tie fastening tool 100 provided in Embodiment 1, the main difference being that... Figure 9 As shown, the cable tie fastening tool 100 is divided into two parts: a tool head and a handle. That is, the tool housing 1 of the cable tie fastening tool 100 is divided into two separate parts: a tool head housing 11 and a handle housing 12.

[0134] For the tool head, the cable tie tightening mechanism 2 is disposed on the surface of the tool head housing 11, and the reduction mechanism 3 is disposed inside the tool head housing 11 and connected to the drive shaft of the cable tie tightening mechanism 2. For the handle, the drive motor 4, torque detection module 6, angle detection module 7, and data transmission module 8 are disposed inside the handle housing 12, and the scanning window 51 of the scanning module 5 is disposed on the surface of the handle housing 12. The tool head housing 11 and the handle housing 12 can be detached or connected relative to each other. When the tool head housing 11 is connected to the handle housing 12, the reduction mechanism 3 is connected to the drive motor 4, so that the power of the drive motor 4 can be transmitted to the cable tie fastening tool 100.

[0135] The cable tie fastening tool 100 allows for the detachment of the tool head and the handle. By changing the head of the cable tie fastening tool 100, different sizes, specifications, and models of cable tie tightening mechanisms 2 can be installed on the handle of the cable tie fastening tool 100. Different tool heads can be selected according to different cable ties, thus expanding the applicable scenarios of a single cable tie fastening tool 100.

[0136] The deceleration mechanism 3 is also located in the tool head of the cable tie fastening tool 100 and is connected to the cable tie tightening mechanism 2. This allows the deceleration mechanism 3 with different reduction ratios to be replaced simultaneously when the cable tie fastening tool 100 head is changed, thereby meeting the tension differences between cable tie tightening mechanisms 2 of different sizes, specifications and models (some cable ties can be stretched to 1800 kgf).

[0137] Meanwhile, the drive motor 4, torque detection module 6, and scanning module 5 are located inside the handle of the cable tie fastening tool 100, so that torque detection and tension input functions can be maintained even when the tool head is changed.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
