[0016] The wrench is powered by a battery pack 9, which can be divided into 18V or 36V, and is used to power the power tool in different scenarios. The drive module 7 is responsible for powering the torque sensor 2 and collecting the torque signal fed back by it. At the same time, it drives the DC brushless motor 3 to run, drives the reducer 1 to achieve torque amplification, and controls the operation mode of the DC brushless motor 3 in combination with the torque signal to achieve accurate output torque; the control module 8 is provided with buttons and a display screen, which can realize information interaction with the operator. The control module 8 is connected to the drive module 7 through a serial port. The control module 8 sends the control parameters to the drive module 7 to change the operation process of the tool.

The control module 8 also provides a USB interface 14 and a wireless interface. The wireless interface can be replaced with different wireless methods according to the user's on-site conditions to meet the different connection requirements of the factory. The user can send and receive data to the control module 8 through the interface and connect to its own management system. The wrench is a gun-shaped structure, which can be held in one hand and is suitable for most workstations with low torque requirements and high precision requirements.

[0018] Embodiment 2: When the embodiment 1 is used, the lighting is improved by the lighting element 13 to meet the needs of different operation sites. However, when it is used in a place with low brightness, it is necessary to constantly change the situation around the bolts to be disassembled or installed. The only way is to manually adjust the direction of the entire device to adjust the irradiation angle of the lighting element 13. Based on this, the solution of the embodiment 1 is improved, such as Figure 2 As shown: The lighting element 13 includes a lighting lamp 131 and a deformation block 132; A deformation block 132 is fixed between the lighting lamp 131 and the reducer 1; The deformation block 132 is made of rubber.

[0020] By virtue of the deformable property of the deformable block 132 , the lighting angle of the lighting lamp 131 can be adjusted at will, and adaptive adjustment can be performed according to usage conditions, thereby improving the efficiency of removing or installing bolts.

[0021] Embodiment 3: When the embodiment 2 is in use, the lighting direction and angle of the lighting lamp 131 are adjusted manually, but the position of the lighting lamp 131 needs to be manually stabilized, resulting in reduced stability during the working process.
