The middle joint (4) between bearing arm (3) and basic frame (2), the back joints (5, 5') and adjusting members (7, 7') turned to the bearing frame (1) and the frontal joints (6, 6') of the adjusting members (7, 7'), turned to the basic frame (2), are made as ball-joints. The frontal joints (6, 6') are in the operational position placed regarding the horizontal higher than the back joints (5, 5'). The bearing arm (3) is on the bearing frame (1) made forwardly in direction (20) of movement and in its frontal parts there is made in the height of the basic frame (2) down oriented the bearing console (19).
