Abstract:
A plier tool capable of releasably locking opposed jaws onto a workpiece by a manual one-handed operation, comprising, in combination:a primary lever assembly having:spaced-apart, elongated rigid sidewalls disposed in generally parallel relation to each other to provide a forward jaw end and a rearward distal end;an elongated fixed wedge mounted between the sidewalls and extending toward the distal end and having a forward end adjacent the jaw end;a rigid, elongated, slidable wedge mounted between the sidewalls to slide in contact with the fixed wedge;a manually-slidable adjusting means disposed in contact with both the fixed wedge and the slidable wedge for slidably advancing or retracting the slidable wedge along the fixed wedge; anda secondary lever assembly having:a pivotal jaw member mounted to pivot on the primary lever assembly at a point adjacent the jaw end;an elongated handle member having a forward end pivotally connected to the pivotal jaw member whereby it may be manually pivoted relative to the primary lever assembly, and a rear handle end;a rigid link member having a first end pivotally connected to the handle member at an intermediate point thereon, and a second end movably secured to the slidable wedge whereby sliding advancement or retraction of the slidable wedge is translated to the link member.
