[0006] Furthermore, the flame-spraying hole of the first cartridge fixing piece is oriented obliquely downward toward the outside of the outer frame.

[0007] Furthermore, the first cartridge fixing member includes a first mounting plate connected to the outer frame, a first buckle is provided on the first mounting plate, and an accommodating space is formed between the first mounting plate and the first buckle.

[0008] Furthermore, it also includes a second cartridge fixing member, the second cartridge fixing member includes a second mounting plate connected to the outer frame, a second buckle is arranged on the second mounting plate, and a receiving space is formed between the second mounting plate and the second buckle;

[0009] The flame-spraying hole of the second cartridge fixing piece faces upward and / or obliquely upward on the outer side of the outer frame.

[0010] Furthermore, the outer frame is a circular wheel structure, the first cartridge fixing part and the second cartridge fixing part are both arranged in the outer frame, and a firework nozzle is provided on the outer peripheral surface of the outer frame, and the firework nozzle is respectively connected to the accommodating space of the first cartridge fixing part and the second cartridge fixing part.

[0011] Furthermore, the outer frame includes a first frame and a second frame, and the first frame and the second frame are detachably connected;

[0012] The first cartridge fixing member and the second cartridge fixing member are arranged on the first frame, and the openings of the first buckle and the second buckle face the second frame.

[0013] Furthermore, both the first frame and the second frame are provided with mounting platforms, the mounting platform of the second frame is provided with a second cartridge fixing component, and the opening of the second buckle faces the first frame.

[0016] The present invention also includes a firework comprising any of the above-mentioned firework stands and a firework cartridge installed in a first cartridge fixing member.

[0017] Beneficial effects of the utility model:

[0018] The utility model sets the bottom of the fireworks stand as an arc surface, so that after the fireworks stand is placed, it can be shaken relative to the placement plane along the arc extension direction of the arc bottom surface. The fireworks stand is symmetrically provided with a first cartridge fixing member, in which a fireworks cartridge is installed, and the reverse force generated by the fire of the fireworks cartridge spraying is used to provide the fireworks stand with power to lean to the other side. The arc bottom surface of the fireworks stand is provided with limiters at both ends along the arc extension direction, so as to avoid the fireworks stand from swinging too much, resulting in failure to cooperate with the fireworks cartridge or unstable swinging state and other unexpected movements, thereby ensuring the stability of the swinging state of the fireworks stand and improving the safety of fireworks discharge. The fireworks cartridges in the first cartridge fixings on both sides of the fireworks stand spray fire alternately. After the fireworks cartridges in the first cartridge fixings on one side spray fire, the fireworks stand tilts to the other side, and the limiting piece on the other side limits the shaking amplitude of the fireworks stand. Then, the fireworks cartridges in the first cartridge fixings on the other side spray fire to cause the fireworks stand to tilt back. The fireworks stand swings back to the side where it originally sprayed fire and the limiting piece on that side limits the shaking amplitude of the fireworks stand to that side, thereby achieving a swinging dynamic effect. By arranging fireworks cartridges that spray fire intermittently, the fireworks stand can be alternately sprayed fire repeatedly and multiple times on both sides of the fireworks stand to maintain the swinging state of the fireworks stand.

[0019] The fireworks stand provided by the utility model can be combined with other fireworks cartridges loaded therein and the appearance packaging to achieve various interesting dynamic effects, thus bringing more creativity and possibilities to the fireworks performance.
