Single synchronous belt driving type unmanned aerial vehicle nest centering device

The utility model discloses a single synchronous belt driving type unmanned aerial vehicle nest centering device, and belongs to the technical field of unmanned aerial vehicles. Linear sliding rail assemblies, synchronous wheels and tensioning wheels are mounted on the four walls; one end of the synchronous belt is hung on the synchronous wheel, and the other end of the synchronous belt is hung on the tensioning wheel; the inner side surface of the synchronous belt is hung on the toothed idle wheel, and the outer side surface of the synchronous belt is hung on the tensioning idle wheel; the synchronizing wheel is connected with a driving motor; the four centering rods are mutually staggered and distributed in a # shape to form a size-adjustable rectangular frame; the two ends of each centering rod are installed on the linear sliding rail assemblies. The two ends of each centering rod are connected with the synchronous belt, so that the moving directions of the two centering rods in the same set are opposite.
