ABSTRACT:
Spring-tension pliers are disclosed having two clamping arms (2, 3) mounted see-saw fashion on a pivot pin (1), the arms forming a handle (4) with their legs, the legs being pivotable toward one another against the force of a spring (5) to open a clamping mouth formed by the other ends of the legs (6), with clamping jaws (7) being associated with the free ends of the clamping legs (6). The clamping jaws (7) are pivotable around a pivot axis (8') parallel to the pivot joint axis, end sections (9) of the clamping legs are rounded concentrically with respect to jaw pivot axis (8'), and these rounded areas (11) each fit into a correspondingly rounded recess (10) of the clamping jaws.
