TORQUE-CORRECTABLE TORQUE WRENCH AND TORQUE CORRECTION METHOD THEREOF

摘要

A torque wrench includes a mechanical structure and an electronic structure. The mechanical structure includes a tubular body, a flexible rod, an abutment member, an elastic member, a trip mechanism, an adjustment mechanism and a mechanical scale indication mounted in the tubular body for indicating the set torque of the wrench. The electronic structure includes at least one torque sensor and a display unit. When correcting the torque value of the mechanical structure, a force is applied to the wrench and the torque sensor detects the trip torque value of the wrench. The torque value of the mechanical structure is adjusted to match the torque value detected by the torque sensor so as to eliminate the error of the torque value of the mechanical structure.

1. A torque-correctable torque wrench comprising:
a tubular body; an operation head positioned at a front end of the tubular body; a mechanical torque mechanism disposed on the tubular body, the mechanical torque mechanism having a mechanical torque display assembly, the mechanical torque display assembly serving to show the mechanical torque value of the torque wrench by means of scales and indication mark; and an electronic torque sensation mechanism disposed on the tubular body, the electronic torque sensation mechanism having an electronic display screen for showing the electronic torque value of the torque wrench, the read values of the scales of the mechanical torque display assembly being adjustable in a longitudinal direction of the tubular body.
