The fixing head (1), joined to the upper end of the support column attached vertically movable between the three legs, is provided with a central opening (3) with at least one inner step (3.1, 3.2, 3.3) for the insertion of various kinds of bolts protruding from the lower surface of the individual telescope. Two square head bolts, serving as abutments during the adjustment of the position can be screwed into threaded bores (5, 7) positioned on top of the head (1). Three mounting areas (15, 17, 19) are created by three curved recesses (9, 11, 13), each provided with a tangential bore (21, 23, 25) for the accommodation of a fixing bolt. |
