ABSTRACT:
A torque detection device on a power tool includes at least one resistive strain gauge connected to an outer periphery of the shaft which is rotatably received in the barrel of the tool and driven by a motor. At least one conductive collar is mounted to the shaft and electrically connected to the at least one resistive strain gauge. A display device includes a display screen which is located at an outer periphery of the barrel and electrically connected to at least one signal member which is electrically connected to the at least one conductive collar. The at least one resistive strain gauge is deformed together with the deformation of the shaft so as to transfer the deformation of the at least one resistive strain gauge to electronic signals which are displayed by digits in the display screen.
