Torque wrench with a long flexible rod, one end containing the handle and the other end with square head or hex head, square head or a hex head set for the sleeve, with the ball stuck. At the top is also equipped with a long pointer. Scale plate fixed to the handle seat, each grid scale is 1N (or kg / m). Before use, first installed in the wrench to adjust the indicator to the desired torque, and then pulled wrench, when the reach the predetermined torque, the pointer on the indicator will turn to the pin side, the last pointer and pin collision through the speaker signals or sensing signals inform the operator.
