The rotary knob includes a handle bowl (1), a coupling part (2) for attaching it to the casing, a bush (3), a cover disk (4), a bolt (5) and a clamping disk (6). The clamping disk is guided into the handle bowl and is able to rotate on the bush, so that as the handle bowl is rotated, the clamping dish moves synchronously with it to move the bowl along. |
