[0002] As the name suggests, a digital torque wrench is a torque wrench with a digital display. It prompts the user through a digital display or LED light, and the torque setting can also be completed through buttons and digital displays. It is more convenient and easier to operate than a non-digital torque wrench.

[0003] When the digital torque wrench is working, the torque is displayed on the display screen. This setting is convenient for the user to observe the torque size in time. However, the operating environment is relatively complicated when the torque wrench is used. When the torque wrench is in use, the digital display screen is easily blocked by obstacles or scratched, making it impossible for the operator to read the torque value in time, and even causing the digital display screen to be scratched and damaged.
