发明名称 Self adjusting utility pliers
摘要 Self-adjusting pliers including first and second members each handle portions and jaw portions. The first member defines a rack having a plurality of teeth. A rack engagement structure is mounted to an intermediate portion of the second member and positioned adjacent the rack. During initial manual movement of the handle portions towards one another, the rack engagement structure travels in disengaged, spaced relation with respect to the rack. Then, after the jaw portions engage opposing sides of a workpiece, continued movement of the handle portions towards one another causes movement of the rack engagement structure toward the rack until the rack engagement structure engages the rack. The rack engagement structure has a movement restrictive portion being cooperable with the rack so as to limit the movement of the rack engagement structure toward the rack when the jaw portions contact one another in the absence of a workpiece therebetween.
