摘要

The device has a blade root (4') fixed on a cover of a sleeve (3) by a fastener pin (8). A sliding reel (5) is used on a cylindrical barrel of the sleeve for enveloping and blocking rotation of the root around the pin, and releases the pin for allowing rotation of the blade when the blade is folded-up by a translation of the reel toward a rotor center. A side abutment (7) is located or fixed on a side of the root, and rests against sides of arms of the cover of the sleeve so as to obtain fast alignment of axes of the sleeve and the root.
