摘要： A hand tool having a first hand tool member assembly having a jaw portion, a tension assembly, and a cam assembly and a second hand tool member assembly having a jaw portion. The hand tool further has a jaw portion first pivot point coupling the first hand tool member assembly to the second hand tool member assembly and a jaw portion second pivot point coupling the first hand tool member assembly to the second member assembly. The jaw portion second pivot point located closer to the first member and second member jaw portions than the jaw portion first pivot point. The first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion are structured to close together in a three-phase motion consisting of a first pivot phase, a transition phase and a second pivot phase, the first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion pivot relative to each other about the jaw portion first pivot point during the first pivot phase and pivot relative to each other about the jaw portion second pivot point during the second pivot phase. The cam assembly is structured to engage the tension assembly when the first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion contact a workpiece thereby initiating the transition phase between the first pivot phase and the second pivot phase wherein the rotation about the jaw portion first pivot point is halted causing the jaw portions to rotate about the jaw portion second pivot point.
