Torque wrench with digital display

Abstract

A torque wrench with a digital display, characterized in that it comprises a torque output head (100), a shaft body (200), a first control unit (300) and a second control unit (400); wherein the torque output head (100) is located at one end of the shaft body (200), wherein a side wall of one end of the shaft body (200) facing the torque output head (100) is provided with a strain gauge, wherein the strain gauge is configured to detect a deformation amount of a rear part of the torque output head (100); and wherein the first control unit (300) is arranged on the shaft body (200), wherein the second control unit (400) is arranged separately relative to the shaft body (200), wherein the first control unit (300) and the second control unit (400) are connected to each other via signal technology, and wherein the first control unit (300) is further connected to the strain gauge via a line.
