Description

[0002] With the rapid development of my country's industry, the aviation, aerospace, shipbuilding, wind power, and nuclear power sectors are placing increasingly stringent demands on equipment assembly quality. Accurate tightening torque is particularly critical in equipment like diesel engines, motors, and generators. Consequently, manufacturers across various industrial sectors are placing increasing emphasis on the accuracy of torque measurements on tools like hydraulic wrenches, manual wrenches, and torque multipliers. The accuracy of torque on these tools directly impacts assembly quality, and as a result, users attach great importance to torque measurement on tightening tools.

[0003] However, due to the large variety of tightening tools that need to be measured, especially the different specifications of each type of tightening tool, the sizes of tightening tools also vary depending on the torque value.
