Abstract
A driver includes a housing, a driveshaft rotatable with respect to the housing and a chuck. The chuck includes a generally cylindrical body and a nut rotatably mounted relative to the body so that relative rotation between the nut and the body moves the chuck toward an open or closed position. A first sleeve is rotationally fixed to the nut and is axially movable and rotatable with respect to the body. A collar is disposed operatively between the first sleeve and the body. The collar is rotationally fixed to and axially movable with respect to the body and is axially fixed to and rotatable with respect to the first sleeve so that the collar moves axially with the first sleeve and with respect to the body between a first axial position and a second axial position. The collar is rotatable with respect to the housing in the first position and is rotationally fixed to the housing in the second position.
