With the continuous improvement of assembly quality requirements in industries such as new energy vehicles, aerospace, and rail transit, traditional pneumatic and manual tightening tools are accelerating their upgrade to high-precision digital torque systems and electric servo tightening tools.　

In the field of aerospace manufacturing, the failure of tightening a bolt can lead to serious consequences　

With the rapid evolution of new energy vehicle manufacturing towards flexibility, digitization, and traceability, traditional tightening tools that rely on manual recording or independent operation are no longer able to meet the quality management needs of modern production lines.　

The torque output accuracy of bolt tightening tools will inevitably drift in high-intensity and high-frequency usage environments.　

In the assembly and maintenance processes of industries such as automobile manufacturing, engineering machinery, and rail transit, traditional mechanical torque wrenches (such as pointer type and preset type) have long dominated.
