Specifically, in one embodiment, the outer cylinder 110 is a cylinder with an integral structure, and one end of the cylinder is provided with an opening and is communicated with the inner space, and the spacer 130 is clamped on the inner side wall of the outer cylinder 110 and divides the inner space of the outer cylinder 110 into two areas, namely an inner bullet accommodating portion 111 for accommodating the inner bullet 120 and an ignition powder accommodating portion 112 for accommodating the ignition powder 140. The through holes 131 formed in the spacers 130 allow direct or indirect contact between the inner shell 120 and the primer 140. The igniting powder 140 may be similar to chemical components (including potassium chlorate and red phosphorus) of "throwing gun" in market, and may explode when being impacted or extruded to generate open fire or spark in a short time, and the burning speed of the igniting powder 140 in the igniting powder accommodating portion 112 may be dynamically adjusted by adjusting the components of the igniting powder 140, so as to achieve the effect of delaying the detonation of the inner bomb 120, and avoid the risk of the frying cylinder.

The piston 240 is configured to reciprocate in the piston cavity 250 under the action of the elastic member 220 during the compression and the return of the elastic member 220. When the elastic member 220 is compressed, the piston 240 moves in a direction away from the firework 10 to suck air out of the piston chamber 250. When the elastic member 220 is restored, the piston 240 moves in a direction approaching the firework 10 to discharge air in the piston chamber 250, and the discharged air collides with the bottom cap 150 of the firework 10. The firework 10 is exposed to compressed air, and is fired on the one hand, and the primer 140 on the other hand produces an explosion and ignites the inner charge 120 to obtain the effect of the firework being displayed in the air.
