Apparatus for measuring torque of a torque tool by using an indirect structure

A torque tool, comprising:

• a main body, the main body comprises a tool head, a driving head, and a handle body, wherein the driving head is arranged on the tool head and the handle body is connected with the tool head;
• a microstructure part, the microstructure part is arranged on one side surface of the main body, and the microstructure part further comprises a sensing structure for sensing the strain or displacement generated by a force exerted on the torque tool and converting the strain or displacement into an electrical signal;
• a signal processing part, the signal processing part comprises a signal operator and a display, wherein the signal operator is electrically connected with the microstructure part and the display is electrically connected with the signal operator, and the signal processing part is capable of receiving the electrical signal and performing signal process;
• and
• an electrical power part, the electrical power part is arranged in the main body and is capable of providing electrical power for the microstructure part and the signal processing part.
