Abstract: A device comprising horizontal and vertical shafts wherein the horizontal one is connected to a handle while the vertical shaft is operatively connected to a movable member of the clutch. Geometrical axes of said shafts are lying in a common plane, whereas shafts for transmitting rotation from the horizontal shaft to the vertical one are interconnected through a Geneva mechanism with a driving member of said mechanism being fixed to the horizontal shaft while a driven member thereof is fixed to the vertical shaft. It is possible with such an arrangement of the device to reduce the force applied by an operator of the machine tool to the clutch control handle.
