The invention relates to a rod or shaft (1) with radial bristles (2) that project through holes (7) of a casing (6) and can be hidden within same, complemented with a handle (2) provided with a groove (4) wherein a manual actuating lever (5) can be moved in order to hide or project the bristles (2). The manual actuating lever (5) is pivotable forwards and backwards and is stable in any of said positions, so as to keep the bristles in the hidden or projected form thereof in a stable manner. In a variation on the embodiment, the actuation is carried out by means of a rack (9) with a toothed section (10) provided with a lever or trigger-type element (5'), and in another embodiment, the actuation is carried out by means of a lug (12) mounted in a rotary casing (8'), said lug engaging, on the inside, in a helical groove (11) provided in the inner part associated with the shaft or rod of the bristles (2). |
