摘要:
The present invention discloses an integral-type combined firework, in which several tubular holes whose central longitudinal axes are parallel to each other are uniformly distributed on 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 one small through hole that penetrates through the bottom of the body and is provided with a spreading fuse, the body, the tubular holes and the small through holes thereof are an integrally molded structure; the bottom in each tubular holes is provided with propellant powder and connected with the spreading fuse, the propellant powder is provided with an inner cylinder or an effect powder on it. The integral-type combined firework using the above solution has standard specification, firm structure and results in high production efficiency; moreover, the original fuse connection at the side of the cylinder body is changed into the fuse connection at the bottom, and the fuse connecting holes are mechanically molded with a consistent size of the hole and precisely controlled distance between holes, therefore, the launching time is accurate and safety is good.
