In this embodiment, in the first cartridge 3, the size, volume and other parameters of each powder part can be adjusted accordingly according to the propulsion process of the wing structure 2, wherein, since the first elastic member 6 is used to realize the reciprocating flapping of the wing structure 2, then, in the first cartridge 3, each powder part is controlled to be set to stop pushing after the wing structure 2 is pushed out, so that the first elastic member 6 can effectively make the wing structure 2 be elastically retracted, and after the wing structure 2 is retracted, the next powder part in the first cartridge 3 starts to ignite, so as to push the wing structure 2 out again, so as to realize the reciprocating flapping of the wing part. Of course, the manner in which the fireworks powder is filled in the first cartridge 3 may also be changed. For example, the fireworks powder is continuously filled into the first cartridge 3 as a whole, and the wing structure 2 is pushed to the maximum opening position only during the first ignition. The subsequent flapping effect is completely achieved by the elastic restoring force of the first elastic member 6 itself. Therefore, the filling of the fireworks powder in the first cartridge 3 only needs to be sufficient to push the wing structure 2 and enable the wing structure 2 to flap back and forth under the action of the first elastic member 6.

[0081] The above is only one solution of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
