The adjusting trapezium is moved upwards or downwards in a position during releasing of outer clamping screws (12) by moving adjusting wedges in opposite directions. The wedges are adjusted by rotating internal spindles (15). A frame part is connected with the adjusting trapezium by an internal clamping screw (13) and an internal clamping plate (8).
