Abstract
A clutch control mechanical device is disclosed for the brush axle of a vacuum cleaner. The clutch control mechanical device is located at the undercarriage of the machine with a pressure control shaft extending out of the inner sides of the undercarriage. At the corresponding position, the underside of the upper body joining the undercarriage is equipped with a pressure control piece so that when the upper body is in a vertical position to the undercarriage, the pressure control piece shall press down on the pressure control shaft of the clutch control mechanical device which suspends rotation of the brush axle. When the upper body is in a slanted angle to the undercarriage, the removal of external force shall return the pressure control shaft to its original position by a spring bias which rotates the brush axle.
