Abstract (en)

[origin: WO2004020153A1] A self-adjusting pliers (20) is operable to grasp a workpiece (22) between an upper jaw (24) and a lower jaw (26). The pliers includes an upper arm (28) having a first end and a second end, with the upper jaw at the first end. A jaw arm (34) has a first end and a second end. The second end of the jaw arm is pivotably connected to the upper arm at a main pivot (40) adjacent to the second end of the upper arm, so that the first end of the jaw arm is movable in a circular arc relative to the main pivot. The lower jaw is at the first end of the jaw arm in movable facing relation to the upper jaw so that the workpiece may be grasped between the upper jaw and the lower jaw. An engagement mechanism (86) releasably engages the jaw arm to the upper arm at an engagement position responsive to a movement of the jaw arm relative to the upper arm and responsive to a size of the workpiece grasped between the upper jaw and the lower jaw, to thereby prevent rotation of the jaw arm relative to the upper arm.
