<p>The support (1) has a horizontal holding plate (5) provided with an orifice (10) extending across the plate along vertical direction (Z) perpendicular to the plate. The orifice receives a tool in vicinity of proximal end (3). A base (20) is parallel to the plate, and includes flat surfaces (23, 24) i.e. bearing surfaces, facing the plate. A distal end (4) of the tool rests on one of the surfaces. The plate and the base are moved relative to each other so that the bearing surface is placed at distance measured along the direction, where the distance varies with respect to the plate. An independent claim is also included for a housing for maintaining a tool.</p> |
