At each clamping jaw (1, 2) there is supported a gripping plate (8, 9) tiltable around an axis (5, 6) vertical to the jaw axis. The two hinge quadrangles (3, 4) can be rotatably supported jointly by an axis running parallel to the hinge axes of the hinge quadrangles (3, 4), however, also the two hinge quadrangles can be jointly tiltable around one axis, which runs vertical to the hinge axes (FIG. 3).
