Adjustable tools which may be linked through a coupling so that the tool and the handle are rotatable relative to each other in a released condition and locked relative to each other in a locked position. The tool and the handle may thus be adjusted to have the tool at any desired orientation to the handle and in a locked position in that orientation.

This application is entitled to and hereby claims the benefit of the filing date of Provisional Application Ser. No. 60/682,255 entitled "Adjustable Tools: filed May 18, 2005 by Charles A. Cole.
An indexable tool includes a handle having a first prong formed with a first splined orifice and a second prong formed with a second splined orifice. An indexable body has a third splined orifice aligned with the first and second splined orifices. A splined coupling arrangement rotatably joins and selectively locks and unlocks the handle and the indexable body together. The coupling arrangement includes a push button, first and second adjacently disposed inserts, a retainer, a cap and a spring. In a locked position, the spring is biased to hold external splines of the first and second serrated inserts in common engagement with the first, second and third splined orifices to prevent relative rotation between the indexable body and the handle. In an unlocked position, the push button is pushed against the bias of the spring to move external splines of the first serrated insert into exclusive engagement with the third splined orifice of the indexable body, and to move the external splines of the second serrated insert into engagement with the splined orifice of the second prong enabling rotary adjustment of the indexable body relative to the handle and about the cylinder.
