ABSTRACT:
A pliers having first and second plier arms which intersect and are connected to each other by a pivot pin. The first arm is displaceable stepwise relative to the second plier arm to change the spacing of plier jaws with respect to each other. The first plier arm passes through a free space in the second plier arm. The pivot pin is guided in a hole in the second plier arm and is displaceable transverse to a longitudinal plane of the pliers. The first plier arm is formed with a longitudinal slot with profiled flanks. The pivot pin has a first cross-sectional region in form-locked engagement with the profiled flanks in a coupled condition of the plier arms, and a second thinner cross-sectional region which is freely displaceable in the slot in a releasable uncoupled condition of the plier arms. The pivot pin has a head section at an actuating side which enters a recess in the second plier arm in a pressed actuating condition of the pivot pin. A diameter of the recess is substantially larger than a largest diameter of the head section.
