Helicopter rotor parallel driving and operating device

The invention relates to a helicopter rotor parallel driving and operating device, which comprises a main parallel mechanism, an auxiliary parallel mechanism, an engine, a transmission shaft, a mandrel, three pin shafts, three springs, three auxiliary springs, a stand column, a connecting rod set, a pedal set and the like. The main parallel mechanism and the auxiliary parallel mechanism are similar in proportion and each comprise a movable table, a machine base, three straight rods, three guide rods and a ball rod. Machine bases are mutually and fixedly connected, the two ends of the straight rod are hinged to the movable table and the guide rod, the guide rod slides in vertical holes of the machine bases, and the ball rod penetrates through a through hole of the movable table to be hinged to the machine bases. The engine is fixedly connected with the bases, the mandrel is rotatably connected with the movable table, and two ends of the transmission shaft are connected with an engine shaft and a mandrel univer
