Abstract
A tool driver includes a housing and a rotatable drive shaft extending therefrom. A chuck for holding the tool includes a generally cylindrical body member having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face and threads formed thereon. A nut is in operative communication with the drive shaft so that the drive shaft rotationally drives the nut. The nut engages the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A locking mechanism is mounted to at least one of the housing and the body and is selectively actuatable to a first operative position and a second operative position. In the first position, the locking mechanism rotationally locks the housing and the body with respect to each other. In the second, it permits relative rotation between the body and the housing.
