ABSTRACT:
Plier-type hand tool comprises a frame having spaced-apart jaws and a fixed handle extending therefrom. One of the fixed jaws has a ram therein which is reciprocable towards and away from the other jaw. The actuating means for moving the ram comprises a movable handle which is pivoted to the frame. Closing of the handles causes two toggle mechanisms to be straightened which are concatenated with the ram. The arrangement of the toggle mechanisms is such that a relatively deep throat is provided between the jaws for the acceptance of a wide workpiece such as a flat electrical cable. A removable tension member may be provided on the ends of the jaws to prevent excessive flexure of the jaws during use of the tool.
