Title: Cordless motor assisted torque wrench

Abstract: A cordless motor assisted torque wrench. In an example embodiment, the torque wrench includes an elongated housing adapted to enclose an elongated battery pack, a drive head pivotably connected to a first end of the elongated housing at a pivot connection, an electronic torque setting device operable to receive a desired torque setting from a user, a torque sensing device for sensing a level of torque applied by the wrench to a workpiece, a motor disposed within the head, and a torque limiter configured to limit the torque applied by the wrench to a workpiece based on the desired torque setting and the level of torque sensed by the torque sensing device. The elongated housing preferably includes a first segment and a second segment slidably coupled to form a telescopic elongated housing that is configurable into at least two lengths.
