Small-size and high-precision fullerene flap actuating mechanism

The invention discloses a small-size and high-precision fullerene flap actuating mechanism, and belongs to the field of unmanned aerial vehicle wings. The fullerene flap actuating mechanism comprises a first connecting rod, a second connecting rod, a connecting rod frame, a third connecting rod, a fourth connecting rod, a fixed rack and a steering engine, the fixed rack is installed in a wing, and the outer contour of the fixed rack is matched with the upper and lower surfaces of the rear edge of the wing to serve as a fixing piece of the whole actuating mechanism; the first connecting rod, the second connecting rod, the connecting rod frame and the third connecting rod are all of straight rod structures, and connecting through holes are formed in the two ends. The fourth connecting rod is a special-shaped rod, serves as an output part of the whole mechanism and is connected with the wing surface of a trailing edge flap, one end of the fourth connecting rod is a straight rod, and the outer contour of the othe
