The invention relates to a helicopter coaxial double-parachute rotor parallel driving device. The helicopter coaxial double-parachute rotor parallel driving device comprises a rotor mechanism, a base, a movable table, a ball rod, three driving branches, a driving mechanism and a plurality of spring branches; and the rotor mechanism comprises a movable table, a mandrel, an inner sleeve, an outer sleeve, a pull rod group, an upper paddle group, a lower paddle group, an upper umbrella rod group, a lower umbrella rod group, a gear group and a lead screw motor. The upper and lower paddle groups are rotationally connected with the convex circular truncated cones of the inner and outer sleeves, and the movable table is rotationally connected with the inner and outer sleeves; the two ends of the three driving branches are hinged to the base and the movable table to drive the rotor mechanisms to swing to change the course; the engine is horizontally and fixedly connected with the engine base, and an engine shaft drives the inner sleeve and the outer sleeve to rotate forwards and backwards through the transverse shaft, the two bevel gears, the two bevel gears, the two transmission shafts and the gear group; the lead screw motor drives the paddle group to change umbrella angles through the mandrel, the pull rod group and the umbrella rod group; and the spring branches divert rotor loads to the engine base. The invention has the advantages of flexible course change, high navigational speed, large lift force, simple structure, good stability and the like.
