ABSTRACT:
The resiliently biased movable tool jaw in, for example, a strap applying tool is maintained in closed contact with the other jaw of the tool against a counteracting force during a critical phase of the tool cycle by the selective deployment of a lock pin engageable with the movable jaw and which is operatively coupled to an actuator cooperative with a reciprocating plunger employed to drive the movable tool jaw into its closed position. Movement of the lock pin is synchronized with the movement of the plunger to insure correspondence between the relative positions of the lock pin and the movable jaw.
