Patent ID: 8016279

Claim:
A jaw assembly comprising: two jaw members; said jaw members having a length D 5 , a height D 6 and a width D 1 along the majority of the length of said jaw member; each of said jaw members having a base end with a flat space on facing surfaces of the jaw members, said flat surface having a width of D 2 , D 2 being less than D 1 , an angled surface extending from D 1 to D 2 , said angled surface having a length D 7 such that a first open space is formed between the flat surfaces and a second generally V shaped open space is formed between the angled surfaces when the facing surfaces are aligned; a cam; said cam comprising a disc having an x and a y axis that intersect at a center point of the disc, said axes being horizontal and vertical respectively, two side surfaces, and a perimeter surface with a width D 8 , a lever extending radially from the perimeter surface of the disc such that the longitudinal axis of the lever is substantially parallel to the x axis, and a pivot pin transversing the disc and extending substantially perpendicular to the side surfaces of the disc; said pivot pin being located off set from both the x and y axes, and located on the opposing side of the y axis from the lever and on the same side of the x axis as the lever; said cam pivotally mounted via the pivot pin between the jaw members at the flat surface in said first open space; and wherein the off set of the pivot pin is configured such that a progressively increasing portion of the disc is rotated into the V shaped open space as the lever is moved from a first position to a second position.
