[0018] Please see Figure 1-3 The signal processing terminal 2 has control buttons 16 movably mounted on its surface, and the outer casing 1 has through holes corresponding to the display screen 4 and control buttons 16. A force sensor 5 is embedded in the top of the signal processing terminal 2, and both the display screen 4 and the force sensor 5 are connected to the signal processing terminal 2 via signal transmission.

[0019] Please see Figure 1-3Force sensor 5 employs a high-precision pressure sensor with a measurement range of 1-1000 Newtons and an accuracy of ±0.5 Newtons. Installed at the contact point between the measuring instrument and the stainless steel cable tie, it can sensitively detect the tension generated during the tightening process of the cable tie and convert it into an electrical signal. Signal processing terminal 2 is electrically connected to force sensor 5, receiving the electrical signal from force sensor 5. After amplification, filtering, and analog-to-digital conversion, the analog electrical signal is converted into a digital signal (this technology is well-known and will not be described in detail here), facilitating subsequent processing and display.

[0020] Please see Figure 1-3 The force sensor 5 has a detachable movable clamp 6, and a positioning clamp 7 is detachably installed on the top of the housing 1 via bolts. The movable clamp 6 and the positioning clamp 7 are used to securely connect the measuring instrument and the stainless steel cable tie tightening tool, ensuring that their relative positions are stable during testing and guaranteeing the accuracy of the test data.

[0021] Example 2, please refer to Figure 4-5 A cover 8 is hinged to the front end of the outer shell 1. A handle 9 is fixedly installed on the surface of the cover 8. A protrusion 10 is fixedly installed on the front end of the outer wall of the cover 8. A groove 11 corresponding to the protrusion 10 is opened on the front outer wall of the outer shell 1. The cover 8 is engaged with the outer shell 1 through the protrusion 10 and the groove 11.

[0022] Please see Figure 4-5 The protrusion 10 has a positioning hole 12 inside, and a positioning block 15 is engaged at the opening of the positioning hole 12. The end of the positioning block 15 inserted into the positioning hole 12 is hemispherical. The protrusion 10 is installed inside the groove 11 through the positioning hole 12 and the positioning block 15. The positioning block 15 is fixedly installed on the side wall of the groove 11. The surface of the protrusion 10 has an arc groove 13 and a guide opening 14 corresponding to the positioning block 15. The positioning hole 12, the arc groove 13, and the guide opening 14 are interconnected.

[0023] Working principle: 1. Powering on: Press the power button on the data display module on the instrument's casing to turn on the instrument. At this time, the data display module will perform a self-test, and the screen will display relevant startup information and the initial settings interface. After the self-test is complete, the display will show "0.00", indicating that the instrument is ready to perform measurements.

[0024] 2. Measurement: A stainless steel cable tie tightening tool is used to tighten the stainless steel cable ties. During tightening, the force sensor assembly senses the tension on the cable tie in real time and converts it into an electrical signal, which is then transmitted to the signal processing unit. The signal processing unit amplifies, filters, and performs analog-to-digital conversion on the electrical signal, before transmitting the digital signal representing the tension value to the data display module. The display screen shows the current tension value of the cable tie in real time. The operator can adjust the tightening force of the cable tie tightening tool according to the displayed value to achieve the desired tightening tension.

[0025] 3. Function Operation: To switch the display unit of the tension value, press the unit switching button on the data display module to switch between units such as Newtons and kilograms. To zero the current measurement data, press and hold the data zeroing button until the display shows "0.00", then release the button to complete the zeroing. To maintain the peak tension value during the measurement process, press the peak hold button. The display will then continuously show the maximum tension value during the measurement. Pressing the button again will cancel the peak hold function.

[0026] 4. Power off: After the measurement is completed, press the power button to turn off the measuring instrument. If the measuring instrument will not be used for a long time, it is recommended to remove the internal lithium battery and store it properly to extend its lifespan.

[0027] In summary, this stainless steel cable tie tightening tool tension testing and measuring instrument transmits the tension generated by the cable tie to the force sensor 5 through the instrument's movable clamp 6 when the cable tie is tightened. The force sensor 5 converts the tension into an electrical signal, which is processed by the signal processing terminal 2 and displayed digitally in real time on the display screen 4. The operator can adjust the operating force of the stainless steel cable tie tightening tool according to the displayed tension value to achieve the appropriate tightening force.

[0028] This tension testing and measuring instrument can accurately measure the tension of stainless steel cable tie tightening tools, offering high measurement accuracy and a small error range, providing reliable data support for cable tie tightening operations. Its reasonable structural design, convenient operation, and easy installation and disassembly make it suitable for various models of stainless steel cable tie tightening tools. Furthermore, by accurately controlling the cable tie tightening tension, it effectively avoids problems such as cable tie loosening or object damage caused by improper tension, improving work efficiency and quality while reducing maintenance costs.

[0029] When the tension testing instrument of this application is not in use, the cover 8 is rotated 180 degrees to close, and the protrusion 10 at the front end of the cover 8 is inserted into the groove 11. At the same time, the positioning block 15 also precisely enters the positioning hole 12 along the sliding groove 13 on the outer wall of the protrusion 10, thereby locking the protrusion 10 in the groove 11, thus locking the cover 8 and ensuring that the cover 8 will not be opened accidentally.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
