ABSTRACT:
A blade mechanism includes a driving ring. At least two blades each have a pivot, a driving pin and an opening. The pivot of one blade is placed between the pivot and the driving pin of the other blade. The blades are rotated around the pivots by the driving ring. The opening is formed in the blades so as not to block the rotation of the other blades.
