  • Patent number: 8322285
    Abstract: A combined firework is disclosed. In the combined firework, several tubular holes whose central longitudinal axes are parallel to each other are uniformly distributed in a body, the tubular holes have openings upward and bottom ends closed. The closed end of the bottom of each tubular hole is provided with two small through holes penetrating through the bottom of the body and respectively provided with an inward fuse and an outward fuse in series connection. The body, the tubular holes and the small through holes thereof are an integrally molded structure. On the bottom in the tubular hole propellant powder is provided and connected with the outward fuse and the inward fuse. On the propellant powder an inner cylinder or effect powder is provided.
