This invention discloses a continuous fuse structure (2-10) for combination fireworks. The fireworks combination comprises one or more fire unit(s), which consists of several successive adjacent single tubes (1), with at least one fire-hole (5,7,10) located on each side wall of the single tube. Fire passes along the long segment fuses (3) throughout the single tube of each fire units. The long segment fuses are in detour and folded sections (6,9) corresponding to the number of single tube. According to the fire-sequence, each folded section of the detour is sequentially inserted in the fire holes of each single tube. In case a combination firework comprises of a multiple of fire units, flame spreads along fuses of the separates units and pass through the units.
