[0017] The main control chip 1 can be a commercially available microcontroller or a chip with integrated BLE, such as the CH582M. Figure 1 As shown, it has multiple GPIO pin interfaces (i.e., the main control chip 1 has multiple GPIO pin interfaces), ADC interface, UART interface, SPI interface, I2C interface and PWM output terminal.

[0018] The current measurement circuit 2 is connected to the main control chip 1 via a GPIO pin interface. It can include a contact-type current measurement unit and / or a non-contact-type current measurement unit. The contact-type current measurement unit detects whether the circuit is energized by contacting the circuit under test; the non-contact-type current measurement unit detects changes in the electric field around the circuit through electromagnetic induction. The current measurement circuit 2 is connected to a GPIO pin interface of the main control chip 1 to convert the detected analog signal into a digital signal. The specific structure of the current measurement circuit 2 is not limited, as long as it can achieve the above functions. Its structure can preferably be as follows: Figure 2 shown.

LED indicator 4 is connected to one or two other GPIO pin interfaces of the main control chip 1; this LED indicator 4 includes a red LED and a green LED, the green LED indicating circuit safety and the red LED indicating circuit danger (see...). Figure 4 The main control chip 1 receives signals from the power measurement circuit 2, determines whether the line is energized based on the signal strength, and controls the working status of the buzzer 3 and LED indicator 4. When a live wire is detected, the buzzer 3 sounds a continuous alarm; an active or passive buzzer can be used. The LED's on / off state can be controlled via GPIO, ensuring clear visibility even in daylight.

Figure 6 As shown, this allows it to connect to the main control chip 1; the charging circuit 7 can also use a charging management chip or discrete components to divide the 5V voltage to 4.2V to support constant current and constant voltage charging of the lithium battery. The lithium battery 8 is connected to the charging circuit 7, and its interface circuit is as follows: Figure 7 As shown; the lithium battery 8 is preferably a polymer lithium battery with a nominal voltage of 3.7V, which provides power to the entire intelligent module; the lithium battery 8 is connected to the charging circuit 7 and the main control chip 1 monitors the battery power. When the power is below 20%, the LED indicator 4 will flash to prompt the user to charge.

[0022] The TOF ranging sensor 11 is connected to the main control chip 1 via an I2C interface, and its structure is as follows: Figure 9 As shown. The TOF distance sensor 11 is preferably a laser TOF sensor, with a measurement range of 0.1m-2m and an accuracy of ±1cm. The TOF distance sensor 11 is installed in a suitable position on a clamping tool and can measure the length of the line to be cut.

[0023] In this embodiment, the intelligent module integrated into the pliers also includes a USB interface 10. The USB interface 10 is connected to the charging circuit 7 to provide charging power to the lithium battery 7. It adopts a USB Micro interface or a Type-C interface and supports 5V / 1A charging input. Figure 8 As shown. The intelligent module integrated into the clamp tool also includes a digital display module 5. The digital display module 5 is connected to the main control chip 1 via an interface and is used to display information such as the measured voltage value, distance measurement result, and battery level. The digital display module 5 uses a 0.96-inch OLED display screen or digital tube, which has a backlight function and can be clearly displayed even in low-light environments (e.g., ...).
