A gearing mechanism (12) has four rods, of which two inner rods (15,16) are fastened to swivel via a fixed joint (19) and two outer rods (17,18) each link to jaw supports (6,7) via joints (20,21) on the inner rods and extra joints (13,14). A moving part (11) in a linear drive (8) links to the inner rods via a linkage element (22).
