Portable screw driver for e.g. screws in aeronautic industry, has transmission unit i.e. connection unit, placed between gripping handle and body, and measurement unit i.e. sensor, measuring information representative of maintenance efforts

摘要

The screw driver (30) has a housing body (31), and an end unit that is likely to be involved in rotation by an electrical motor. An axis of the end unit is tilted with regard to the body. A set of transmission resources is placed between the motor and the end unit. A transmission unit i.e. connection unit (38), is placed between a gripping handle (35) and the body for maintenance of the screw driver by an operator and for opposing screwing torque. A measurement unit i.e. sensor (39), measures information that is representative of maintenance efforts.
