Abstract
A tool holding device for persons with limited hand mobility has complementary tool handles and socket of cylindrical or conical form. The socket is integral with a rotatable part and may have an upper open section above the socket diameter permitting tools to be snapped into rotatable relationship with the socket. The rotatable base for the socket is surrounded by an annular fixed housing, and housing and socket base have complementary facing O-ring grooves above which the housing has a locating flange turned inward over the rotatable socket base. The O-ring locates the parts and provides frictional holding force while allowing snap-out snap-in disassembly for cleaning. A strap through the fixed rim retains the parts in assembly and has hook and loop or other easily fastened fasteners for securing the unit to the hand or other limb of the user.
