Claim Text:
1. A tool head comprising: a pair of jaws pivotally attached to each other by a single pivot, each jaw having a frontwardly directed nose, a generally oppositely directed rear face, and a rearwardly directed cam member, the jaws positionable between (i) an open position in which the noses of the jaws are spaced apart and (ii) a closed position in which at least a portion of a forwardly directed nose region of a lateral face region of one jaw is disposed immediately adjacent to and alongside at least a portion of a forwardly directed nose region of a lateral face region of the other jaw; a linearly displaceable member having a pair of forwardly directed cam surfaces in contact with the rearwardly directed cam members of the pair of jaws; wherein upon forward displacement of the linearly displaceable member, camming engagement between the cam surfaces and the cam members results in pivotal displacement of the jaws; and a first stop assembly and a second stop assembly, each stop assembly having a spring assembly directed toward a rear portion of a corresponding jaw, wherein upon pivotal opening of the jaws, a rearwardly directed region of each jaw eventually contacts the spring assembly of a corresponding stop assembly thereby precluding further pivotal opening of the jaws.
