ABSTRACT:
The invention is an improved ratchet wrench with a handle pivotally attached to a rotating head which can be locked into a position either axially aligned with the handle or laterally angled to one side of the handle. A locking mechanism includes a spring-biased, J-shaped structure, having an actuating shaft which passes through the handle and a locking pin which selectively engages one of a plurality of holes defined in a neck of the rotating head. The locking mechanism has a button on the actuating shaft to sandwich the spring against the handle and permit manual depression in order to move the locking pin from a locked to the unlocked position, the locking pin being biased by the spring towards the neck in a locked position. Angling the handle to one side allows the wrench to be used to loosen or tighten bolts where there is insufficient space to use a conventional straight wrench. The ratchet head may also be removed from the handle for use as a palm wrench or for substitution of the ratchet head with a ratchet head of a different size.
