[0046] When describing the embodiments of the present invention, the orientation or positional relationship expressed by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or positional relationship shown in the relevant drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0048] Combination Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, a firework of the utility model comprises: a base 1, a first cartridge 2 arranged on the base 1 and filled with fireworks powder, a wing portion 3 movably connected to the base 1 and symmetrically arranged on opposite sides of the first cartridge 2, and a second cartridge 4 arranged on the wing portion 3 and filled with fireworks powder; in this embodiment, the wing portion 3 and the base 1 are provided with a first elastic member 5a for providing elastic restoring force, one end of the second cartridge 4 is connected to the wing portion 3, and the other end is extended in a direction away from the wing portion 3; in this embodiment, the first lead of the first cartridge 2 is connected to the second lead of the second cartridge 4. In this embodiment, when the wing portion 3 is in the retracted state, the two wing portions 3 are arranged opposite to each other, and the ejection end of the second cartridge 4 (i.e., the end of the second cartridge 4 not connected to the wing portion 3) is opposite to the other wing portion 3.

[0049] Through the above arrangement, the first cartridge 2 and the second cartridge 4 can be ignited simultaneously by igniting the first fuse, wherein the second cartridge 4 generates a propulsion force on the wing portion 3 after ignition, and then the reciprocating flapping of the wing portion 3 is achieved under the action of the elastic restoring force of the first elastic member 5a, thereby achieving a dynamic bionic effect during the fireworks firing process, effectively improving the firing effect and ornamental value of the utility model.

[0050] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the utility model, the second cartridge 4 is arranged perpendicularly to the wing part 3. Through the above arrangement, the second cartridge 4 is arranged perpendicularly to the wing part 3, so that the propulsion force generated by the second cartridge 4 after ignition can more effectively push the wing part 3, thereby making the two opposite wing parts 3 unfold, so that the first elastic member 5a is compressed to generate elastic restoring force, so as to facilitate the retraction of the two wing parts 3, thereby generating a corresponding reciprocating flapping effect.

[0051] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the utility model, in the second cartridge 4, the filled fireworks gunpowder is divided into a plurality of gunpowder parts, and the plurality of gunpowder parts are arranged in series with a second fuse at intervals. In this embodiment, the plurality of gunpowder parts arranged at intervals can realize the effect of segmented driving, wherein the size, volume and other parameters of each gunpowder part and the length of the fuse connected to each other can be controlled to realize the corresponding action control. In this embodiment, in the second cartridge 4, the size, volume and other parameters of each gunpowder part can be adjusted accordingly according to the propulsion process of the wing part 3, wherein, since the first elastic member 5a is used to realize the reciprocating flapping of the wing part 3, then, in the second cartridge 4, each gunpowder part is controlled to be set to stop pushing after the wing part 3 is pushed out, so that the first elastic member 5a can effectively make the wing part 3 be elastically retracted, and after the wing part 3 is retracted, the next gunpowder part in the second cartridge 4 starts to ignite, so as to push the wing part 3 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 second cartridge 4 may also be changed. For example, the fireworks powder is continuously filled into the second cartridge 4 as a whole and the wing portion 3 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 5a itself. Therefore, the filling of the fireworks powder in the second cartridge 4 only needs to be sufficient to push the wing portion 3 and enable the wing portion 3 to flap back and forth under the action of the first elastic member 5a.

[0052] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, according to an embodiment of the utility model, the wing part 3 is connected to the base 1 by a first elastic member 5a, wherein the first elastic member 5a can be a spring (such as a metal spring or a non-metallic material spring).

In this embodiment, in order to ensure the connection stability and elastic recovery stability of the wing part 3 and the base 1, a plurality of first elastic members 5a can be arranged at equal intervals along the edge of the base 1 to ensure the stability of the connection. Further, the plurality of first elastic members 5a can also be set as one body, so that the first elastic member 5a is integrally attached to the connection position of the wing part 3 and the base 1, further ensuring the stability of the connection position.

[0053] like Figure 1 As shown, according to one embodiment of the present invention, the wing part 3 can be movably connected to the edge of the base 1 through the first elastic member 5a. At this time, the first elastic member 5a plays a dual role of fixing the connection position of the wing part 3 and elastic recovery; wherein, the first elastic member 5a is respectively connected to the wing part 3 and the base 1 by bonding, welding, etc., or by an integral molding method. Of course, in another embodiment, the wing part 3 can be connected to the base 1 by a rotational connection, so that the first elastic member 5a is set based on the position of the rotational connection, and further provides elastic recovery force to the wing part 3.

[0055] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, adjacent third cartridges 32 are arranged at intervals, and the intervals between adjacent third cartridges 32 are gradually increased in the direction away from the movable connection portion of the wing portion 3. Through the above arrangement, the fireworks ejection direction of the third cartridge 32 is scattered, so that it can better adapt to the shape of the entire wing structure 31, so that the fireworks of the present invention have better ignition and viewing effects.
