摘要:
A spreading tool (4) for widening a jewelry ring, in particular for pressing an inner ring portion (24) into an outer ring portion (26) of a hollow ring (22), has a plurality of spreading jaws (10), the insides (48) of which bound a receiving space (50), into which a spreading body (52) can be inserted for spreading open the spreading jaws (10), and which form on the outsides (34) thereof a plurality of coaxial ring receptacles (32) each being bounded radially inwardly by circumferentially disposed wall sections (36) of the spreading jaws (10). The ring receptacles (32) have diameters (Dn) that decrease relative to one another toward a free end (40) of the spreading jaws (10), characterized in that the spreading jaws (10) bound the ring receptacles (32) on both sides also in the direction of a main axis (A).
