[0002] Gatling fireworks are a type of fireworks designed to imitate Gatling guns. It is mainly a type of combined fireworks composed of a number of single bead-spitting products distributed in a circle. When ignited, it forms a similar firing effect to that of a Gatling gun. It has a large charge, a fast firing rate, a strong power, and is very interesting, and is deeply loved by consumers. At present, the existing Gatling fireworks include a launch tube, on which a plurality of paper tubes are arranged in a circle to fix the bead-spitting fireworks, and a fuse cover is arranged at the tail of the bead-spitting fireworks. The production of the product is labor-intensive and time-consuming, with low production efficiency and high cost. Utility Model Content

[0005] In a feasible implementation, the axially raised surface of the outer cylinder is flush with the smooth surface.

[0006] In a feasible implementation, the length of the first smooth section is greater than or equal to the second smooth section, and the second smooth section is provided with a matching cover.

[0007] In a feasible implementation, a hollow groove is provided in the middle section to form a handle, which is helpful for reducing weight.

[0008] In a feasible implementation, a finger groove is provided on the handle to facilitate holding.

[0009] In a feasible implementation, the integrated structure is made of plastic.

[0010] In a feasible implementation, the first smooth section and the second smooth section are cylindrical, conical or polygonal in shape, and the cover body is sleeved in the second smooth section.

[0011] The beneficial effects of the utility model are as follows: by developing an outer tube structure made of integrated plastic, the shell is designed along the axial direction to cooperate with a single bead-spitting firework tube for fixation, which is convenient for placement, and a hollow groove is provided as a handle to reduce weight; it also has the advantage of being easy to operate and use, and effectively improves the efficiency of product assembly and reduces the production cost of such products.
