Unmanned aerial vehicle pneumatic auxiliary ejection device

The invention discloses a pneumatic auxiliary ejection device for an unmanned aerial vehicle. The pneumatic auxiliary ejection device comprises a base, a base, a fixed base connector, a high-pressureair pump, an air duct, an objective table, a connecting structure, an ejection height adjusting rod, a rotating rod, an ejection height adjusting rod fixing disc and the like. The system utilizes thelaunching height adjusting rod to adjust the initial launching angle of the launched object. Determining an initial azimuth angle and an initial emission angle; the gas collecting device collects a certain amount of gas to the high-pressure gas pump; gas needed by ejection is compressed through the high-pressure gas pump, the high-pressure gas is transmitted to the high-pressure gas chamber through the ventilation pipeline, at the moment, the high-pressure gas pushes the ejection rod to move towards the ejection baffle, the objective table stops moving after making contact with the ejection baffle, and an ejection obje
