Abstract
A torque indication device for a hand tool includes a handle with a processing unit connected thereto and a head having a driving member connected thereto is rotatably connected to the handle. The head has an insertion which is inserted into an axial recess of the handle. A first notch is defined in a distal end of the insertion. An intermediate member has a second notch defined in a first end thereof and a second end of the intermediate member is a flat surface. A bead is engaged with the first and second notches. A spring is received in the axial recess and a first sensor is clamped between a first end of the spring and the flat surface. A second sensor is clamped between a second end of the spring and an inside of the axial recess. The first and second sensors are electrically connected with the processing unit.
