Miniature bionic flapping wing aircraft

The utility model relates to the technology of miniature aircrafts, and provides a miniature bionic flapping-wing aircraft, which aims to solve the problems of larger volume, complicated structure, poor flight stability, higher flight maneuverability, higher energy consumption and the like of the conventional flapping-wing aircraft, and comprises wings, a rack, a driving component, a steering engine component and an empennage component, the driving assembly comprises a driving motor fixed to the rack, a driving gear, a first transmission gear, a driven gear, a second transmission gear, a left sector gear and a right sector gear. The driving gear is meshed with a first transmission gear, the first transmission gear and a driven gear are coaxially fixed, the driven gear is meshed with a second transmission gear, a crank is eccentrically arranged on the second transmission gear, a sliding guide rod and a sliding groove are further arranged on the right sector gear, and the crank is matched with the sliding groov
