A single-shot firework support with a pre-mounted heat-generation resistance wire and a corresponding fixed pedestal. A plastic support (1) is provide with a heat-generation resistance wire slot (4) at the top, a heat-generation resistance wire (3) is fixedly located in the heat-generation resistance wire slot (4) and two ends of the wire are electrically connected to two metal conductors (12) respectively, the other ends of the two metal conductors (12) are electrically connected to two plate electrodes (13) respectively and fixed at the bottom of the plastic support (1), the plastic support (1) is provided with an upper clamping structure (17) at the bottom, the fixed pedestal (2) is provided with a lower clamping structure (8), the lower clamping structure (8) is correspondingly clamped to the upper clamping structure (17) of the plastic support (1), the fixed pedestal (2) is provided with two elastic electrodes (5) at the top, the two elastic electrodes (5) are aligned with and electrically connected to the two plate electrodes (13) of the plastic support (1), and the elastic electrodes (5) are electrically connected to a socket (10) fixed to the fixed pedestal (2). This structure makes a propellant force completely act on an effect part in exploding high in sky; has a high safety coefficient, and stable and reliable performance; and is convenient and efficient in use. |
