Reversible drill and drive tool II

摘要

A tool includes a pair of spaced apart substantially parallel arms carrying a mounting member to which are detachably connected axially oriented driver and drill elements. The mounting member is moveable along the arms reciprocally between a first position where it is manually rotated to select the axial orientation of the driver and drill elements and a second locked position to hold the driver and drill elements in a selected axial orientation until the mounting member is returned to the first position. The locking function is provided by a spring element actuated upon the mounting member being moved from the first position to the second position to apply pressure against the mounting member while in the second position.
