But many rotor crafts arm folding mechanism and rotor craft

The embodiment of the utility model discloses but many rotor crafts arm folding mechanism and rotor craft, include: fuselage and horn. The one end and the fuselage of horn are connected through the pivot, the horn with the one end that the fuselage is connected is equipped with the fastener, the fuselage with position that the horn is connected be equipped with with fastener complex locking piece,the locking piece is in the fuselage with in the horizontally connect form of horn. Link together fuselage and horn through the pivot, it rotates to make the horn can follow the fuselage junction, the horn can turn into the second connection status by the first connection status that is in horizontal operating condition, set up the locking piece on the fuselage, set up and locking piece complex fastener on the horn, the locking piece can be when the horn be in first connection status with the fuselage, inject the degree of freedom of fastener in three dimensions, can reduce effectively owingto produce the horn that v
