Wrench, has torque gage with main body and drive, and sensor units measuring deformation of spring unit and sending signal to processor, which determines torque value by using signal
摘要
<p>The wrench has a torque gage with a main body (1) and a drive. The main body has a receiving space at an end and is provided with a processor (12). The drive is positioned in the receiving space. The drive has a spring unit, and two sensor units that are provided at the ends of spring unit. The sensor units measure deformation of the spring unit and send a signal to the processor that determines the torque value by using the signal.</p>
