The invention discloses a novel M-shaped synchronous unfolding device for wings of a barrel-shot unmanned aerial vehicle. A wing bearing plate comprises a gunpowder barrel positioning device, a boss, an arc groove, an inner wing shaft, a transmission gear shaft, an inner wing spring pin hole and a rectangular block; the folding wing group comprises an inner wing, an outer wing, teeth, a stepped shaft, a torsional spring and an outer wing spring pin, the stepped shaft serves as a rotating shaft, and the torsional spring is arranged on the stepped shaft; one end, with teeth, of the inner wing is a root and is fixed on the inner wing shaft, an inner wing spring pin is arranged at the horizontal center line, the lower end of the inner wing spring pin is embedded into the arc groove, and an inner wing torsion spring hole is formed in the horizontal center line of one end without teeth and is matched with the lower end of the torsion spring; an outer wing spring pin is arranged at one point of the outer wing horizontal center line, the lower end of the outer wing spring pin is in plane contact with the stepped shaft, and an outer wing torsion spring hole is formed in the outer wing horizontal center line farther from the outer wing rotating shaft than the outer wing spring pin and matched with the upper end of a torsion spring; the gear unfolding mechanism comprises two transmission gears, a rack, a rack transmission rod and a gunpowder barrel. According to the invention, miniaturization of the barrel-launched unmanned aerial vehicle is realized, and transportation and launching in various environments are facilitated.
