High-precision torque wrench

The utility model discloses a high-precision torque wrench, comprising a sense component, a moment arm and a display component. The sensor component is connected with the moment arm. The display component is connected with the sense component via a signal line, so as to display the output. The sense component comprises a forced plate, an elastomer, a group of connection boards, a square drive and a group of strain gages. The group of the connection boards comprises a front connection board and a rear connection board. The forced plate and the elastomer are fixedly arranged between the front connection board and the rear connection board, forming a fixed body. The square drive is disposed on a lower end face of the sense component. The group of the strain gages are arranged on the sense component. One end of the moment arm is fixed to the other side of the rear connection board, for the purpose of applying a force. The display component is electrically connected with the group of the strain gages. By means of the high-precision torque wrench of the utility model, the measured torque value is not affected by the position where the force is applied, so that the scientific and reliable calibration means are provided for test and calibration of torque wrench calibrators.
