ABSTRACT:
A multiple purpose ratchet tool including a reversible, and preferably, lockable ratchet head having an output shaft adapted to receive a tool bit such as a socket or screwdriver blade for use, and also including a main handle portion and an auxiliary handle portion matable to the main handle portion to form a generally cylindrical grippable handle. The main handle portion is pivotally mounted to the ratchet head about an axis perpendicular to that of the output shaft. Releasable main handle portion locking means may retain the main handle portion generally parallel to the output shaft. However, when the main handle portion locking means is released, the main handle portion may be repositioned at any angle up to and including perpendicularly to the output drive shaft axis. The auxiliary handle portion may be pivotally mounted to either the ratchet head coaxailly with the main handle portion pivot mount, or, to and anywhere along, the length of the main handle portion, and is adapted to be releasably, foldably matable against the main handle portion. When pivoted away from the main handle portion up to and including 90.degree., the auxiliary handle portion is useful for torque multiplication to the output shaft. Alternately, the main and auxiliary handle portions together may be pivoted up to and including 90.degree. to the axis of the output shaft to provide useful function similar to that of a conventional ratchet handle. A detent may be provided to releasably retain the handle in the perpendicular orientation.
