ABSTRACT:
A hand tool adapter for bench operation comprising a frame including a cradle adapted to receive one handle of a two-handle hand operated tool. The adapter includes apparatus for securing the handle in place in relatively fixed relationship with the base. An actuator arm is coupled via a linkage to the base and includes a receiver for the other handle of the hand operated tool. The base positions the jaws or working portion of the hand tool to the front of the base available for clearer visibility by the operator. The linkage provides mechanical advantage for the operator to minimize and tend to standardize the force required for actuation of the hand tool. The handle of the apparatus is dimensioned and positioned to provide a clearly defined range of movement from unoperated to operated positions. An adjustable stop limits travel of the operating handle.
