ABSTRACT:
A rotatable knob for fixation of an apparatus support includes a knob shell (1), a coupling part (2) for the connection of the knob shell to the spindle, a sleeve (3) which is connectable to the housing, a cover disc (4) which is secured by the sleeve (3) to the housing, a screw (5) arranged in the knob shell (1) for the setting of the holding force and a clamping disc (6) which cooperates with the knob shell (1) and the sleeve (3). The clamping disc (6) is guided in the knob shell (1) and is rotatably arranged on the sleeve (3) so that, on rotation of the knob shell, (1) the clamping disc (6) executes a synchronous rotary movement with the knob shell (1) and the linear movement with respect to the knob shell (1).
