The present invention relates to an automatic driver with high efficiency which includes an integral type torque meter or a detachable type torque meter (torque measuring device) that is selectively applied to an automatic (electric, air or others) driver tool to tighten or release screws or pieces in order to provide basic functions as a driver and accurately detect a torque value, thereby effectively controlling torque and managing quality. That is, in order to achieve the above-mentioned purpose, the automatic driver according to the present invention which generally comprises: an electric high-speed motor (not shown) mounted inside an upper main body cover (10) and operated by electric power; a holder (40) which is mounted at the lower side of the main body cover (10) and has a driver main shaft (30) connected with a high speed motor (20) mounted therein; and a tool connection bit (60) mounted at a lower end of the main shaft (30) to easily connect a tool further comprises an integral type torque meter (100) mounted inside the main body cover (10) between the driver main shaft (30) and the tool connection bit (60) or a detachable type torque meter (200) which is mounted at the lower part of the automatic driver and which is attached to or detached from the tool connection bit (60) protruding downwardly as occasion demands. |
