Abstract
The tool handle of the invention includes a shank connected via a ratcheting mechanism to a male square drive. A pair of handle wings are pivotally connected to the shank at a transverse pivot hinge such that the handle wings can be changed between a screwdriver-type configuration, an L-shape configuration, a T-shape configuration or other intermediate configurations. When the handle wings are in the fully open position, the handle wings bear against the shank to create a mechanism for transferring power between the handle wings and the tool shank without the need for a separate lock. A quick change adapter having a female drive can be connected to the male square drive such that the tool handle can be used with a wide variety of tools including taps and extractors, sockets, screwdriver bits and the like.
