A device for launching fireworks, the device includes: a plastic plug and a locking base. The plastic plug includes: a resistance heating wire, a slot for accommodating the resistance heating wire, two metal conductors, two plate-like electrodes, and an upper clamping structure. The locking base includes: a lower clamping structure, two spring electrodes, and a circuit connecting socket. The top of the plastic plug is provided with the slot for accommodating the resistance heating wire. The resistance heating wire is fixed in the slot for accommodating the resistance heating wire and two ends of the resistance heating wire are electronically connected with one ends of the two metal conductors. The other ends of the two metal conductors are respectively electronically connected with the two plate-like electrodes and fixed at a bottom of the plastic plug. The bottom of the plastic plug is provided with the upper clamping structure.
