ABSTRACT:
A hand tool for providing telescoping and axial repositioning of an elongate shaft relative to a handle. The handle includes a first closed end and a second open end which defines a hollowed and axially extending interior within which is securably mounted an intermediate sleeve. The elongate shaft includes a first end which is inserted within the handle and sleeve and a second fastener bit engaging end. A plurality of individual apertures are formed along a selected surface of the elongate shaft and are arranged in axially and spaced apart fashion. A lever mechanism is mounted within apertures in the handle and sleeve and includes a detent which seats within a selected one of the individual apertures in the shaft to maintain the shaft in a locked position. A spring biases the detent in the locked position and is counteracted by a trigger which is depressed to unseat the detent from its associated aperture and to permit the elongate shaft to be axially repositioned and the detent subsequently reseated in a further selected aperture of the shaft which defines a desired and axially repositioned length of the shaft.
