Abstract
A driver include: an axis, a shank with a handle engagement portion, and a handle configured to releasably and continuously adjustably fix the shank in position. The handle includes a sleeve with two slots axially oriented, first and second handle portions, a torsion spring between the handle portions, and two retaining balls riding in the two slots and disposed in the first handle portion and biased apart. With the first handle portion in a rotationally neutral position, the retaining balls are pressed against the shank, fixing the shank in position. Rotating the first handle portion with respect to the second handle portion releases the retaining balls and allows the shank to be adjusted in the handle.
