Abstract

Pliers having a pair of handles and a pair of shank members have one member of a die pair for treating a workpiece on each of the shank members. The die members are attached to the inner sides of the shank members rotatably about an axis situated in the tool plane, and a follower is provided to ensure their corotation. The workpiece may be introduced into the die pair frontally or laterally, depending on the rotational position of the die pair. In one embodiment, the die members are also pivotable about axes extending at right angles to the tool plane. The pliers may be used in many applications such as crimping electrical terminals.
