The utility model discloses a firework with novel lead setting, which comprises an outer drum (1) and an inner drum (2) assembled inside the outer drum. A lead hole (3) for a lead (4) to penetrate through is arranged on the outer drum (1), a sealing layer (5) is arranged inside the outer drum, the height of the sealing layer is larger than that of the lead hole, a groove (7) is arranged on the upper surface of the sealing layer, and the depth of the groove is lower than the height of the lead (4). The firework can avoid a fire string when being set off, the lead cannot be flattened or even broken by pressing since the lead does not need to be disassembled and bent, and fire cutoff is eliminated when the firework is set off. In addition, one end or both ends of the lead hole are sealed and separated by the filling layer, the lead linearly penetrates through the groove on the sealing layer, and the groove can be formed simultaneously when the sealing layer is compacted, thereby not only simplifying manufacturing technique, improving production efficiency, favoring the firework to realize streamline mechanical production operation, being capable of preventing the fire string and fire cutoff of the firework, effectively guaranteeing complete setting off of the firework, enhancing setting off effect of the firework, and eliminating safety accident hidden risks of setting off of the firework.
