ABSTRACT:
An impact tool for seating and cutting plural wires in a telephone wire termination block includes a movable cutter containing guide and shear elements having a spacial periodicity which differs slightly from that of terminals of the termination block. A force release mechanism in the tool handle includes a plunger translatable along the axis of the handle that engages a shaft for a stationary cutting head. The plunger passes through a bore of hammer which has a transverse bore sized to receive plural balls that are urged against and retain the plunger with the hammer. A main spring within the handle urges the hammer axially toward the shaft. The hammer passes through a ball-collar, which is axially translatable to remove retention between the hammer and the plunger, allowing the plunger to pass through the hammer bore, so that the hammer is rapidly axially translated by a main spring and strikes the plunger, imparting an impact force to the shaft. A force translation lever then linearly translates a movable cutter, which cuts the wires in rapid sequence.
