A brush is provided which comprises a shaft in the form of a hollow rod (1) through which passes a pressure bar (2) which projects from both of the hollow rod ends. The bar is displaceable displaceable in the hollow rod. When the pressure bar is in the position where it projects out of the hollow rod, at its other end it extends into a fixture bowl (5) against the force of a spring (7), and is articulated to one end of at least one rocker arm (10). At its other end, the rocker arm is connected to the fixture bowl which is shaped to accommodate, on its exterior, a cleaning bowl of soft material, pref. paper. The fixture bowl, under the effect of the pressure bar (2), releases the cleaning bowl by the action of the rocker arm drawing the upper part of the fixture bowl inwards from the cleaning bowl. |
