The first and the second tong members are pivotally connected to one another by a first pin at their hinge ends. A cam is slidably disposed between the first and the second tong member hinge ends. The cam includes a first transverse slot and a second transverse slot having a plurality of incremental and adjacent support surfaces. The first pin extends through the first transverse slot and limits the slidable movement of the cam. A second pin is attached to the second tong member hinge end and extends through the second transverse slot and is adapted to rest against the plurality of incremental support surfaces.
