The sleeve (19) taking the shaft (3) of the instrument is so fixed onto a holder (1) that the holder extends over at most 90 deg of the sleeve circumference and on one side only. The sleeve runs along one outside edge (10) of the holder and is releasably clamped into place in the holder part (7) having triangular section in a plane normal to the axis of the sleeve (19). The one holder part (1) slides relative the other holder parts in a guide (23) parallel to the sleeve axis (19), using a slider (27) to move the holder part (7) as described. When the holder part (7) is mounted on an adapter (9), this in turn swivels on base (8) round a first axis (Y) perpendicular to the slide axis of the part (7), the axis arranged on the underside of the main holder (1). Swivel device (34) serves to swivel the part (7) in relation to the adapter (9). |
