Bent wrench having torque measurement function

Abstract

A bent wrench includes a wrench body including a handle formed with a bent portion, and at least one strain gauge mounted on a connection of the handle and the bent portion to measure the torque of the wrench body. Thus, the strain gauge is extended through the connection of the bent portion and the two ends of the handle and can measure the torque of the wrench body in the optimum manner due to the smallest structural strength of the connection of the bent portion and the two ends of the handle, so that the strain gauge can measure the torque of the wrench body exactly and optimally.
