A revolving fixture intended to support tools or instruments is described. Said fixture comprises first elements for the connection to a carrying structure, and second elements adapted to lock the said tool or instrument and rotatable relative to the said first elements about a main axis. The main feature of this fixture is to comprise means apt to adjust, in a relatively precise, responsive and stable manner, the position of the said tool or instrument with respect to the said axis, so as to position the tip of the said tool or instrument in such a manner as to make it substantially coincide with a point of the said main axis and thus minimize the deviations of the tip of the tool or instrument from the said main axis during the rotation of the said second elements relative to the said first elements. |
