On additional transverse shafts of platform are rigidly fixed blades 6. Additional transverse shafts platforms are articulated by tie rods 11, 12 with vertical flat cams 10 secured on platforms with their inner sides. Device has L-shaped levers 13, having large and small arms. Large arms are pivotally mounted on parts of platforms, further from handles.
