[0030] Referring to Figures 1 to 4 , the present utility model provides a fireworks 100, including a holding arm 10 and a fireworks unit 20 installed on the holding arm 10.

[0031] The holding arm 10 is shaped like a gunstock or a crossbow arm, and the holding arm 10 is made of plastic material or hard cardboard material.

[0032] Specifically, when using paper shell material, the holding arm 10 can be folded and pasted into a specific shape; when using plastic material, it can be directly injection molded.

[0033] The overall shape of the firework 100 resembles a crossbow or a gun, and the firework unit 20 can use multiple firework tubes to launch simultaneously, forming a more beautiful firing effect.

[0034] The structure of the firework 100 of the present invention is described below with a specific example.

[0035] The holding arm 10 includes a firing side 11 and a holding side 12 that are arranged opposite to each other, the firework unit 20 is installed on a side close to the firing side 11, and the firing direction of the firework unit 20 matches the direction of the firing side 11. Persons skilled in the art should know that the firing direction of the firework unit 20 matches the direction of the firing side 11, which means that the firing direction of the firework unit 20 is basically toward the firing side 11, and it is not required to be completely consistent, as long as it does not affect the person holding the holding side 12 or the person behind the holding side 12 who is firing or watching; for example, it can be fired to the left front, right front, or upper front, which can be considered that the firing direction of the firework unit 20 matches the direction of the firing side 11.

[0036] The firework unit 20 includes a bottom support 21, a top support 22, and a plurality of firework tubes 23. The bottom support 21 is fixed to the middle of the holding arm 10, and the top support 22 is fixed to a side close to the firing side 11. The bottom end of each firework tube 23 is fixed to the bottom support 21, and the firing end of each firework tube 23 is fixed to the top support 22. The leads of the plurality of firework tubes 23 are connected together.

[0037] In this embodiment, the width of the top support 22 is greater than the width of the bottom support 21, and the multiple firework tubes 23 are arranged in a radial manner and form a fan ring shape, so that the spraying directions of the multiple firework tubes 23 are dispersed; by setting the shape of the firework unit 20 to be a fan ring, a crossbow-shaped effect is presented, and at the same time, the multiple firework tubes 23 are arranged in a radial manner, so that the ejection direction of the fireworks forms a certain arc range, thereby enhancing the viewing effect of the fireworks.

[0038] It is understandable that in other embodiments, the overall shape of the firework unit 20 may also be a rectangular parallelepiped, a cylindrical shape (such as a machine gun shape), etc., and the arrangement of the firework tubes 23 may also be set as needed.

[0039] Preferably, in this embodiment, the bottom support 21 is in a fan-shaped ring shape. The inner ring surface of the bottom support 21 is closed, and the outer ring surface is open. The bottom end of the fireworks tube 23 extends into the interior of the bottom support 21 through the opening of the outer ring surface, and the bottom end of the fireworks tube 23 is adhesively fixed to the bottom support 21 with glue.

[0040] The top support 22 is in an arc shape, and a plurality of fixing holes 221 are formed in the top support 22. The firing end of the fireworks tube 23 passes through the fixing holes 221 to fix the firing end of the fireworks tube 23 to the top support 22.

[0041] Preferably, in a preferred embodiment, the bottom support 21 is made of plastic material, and a plurality of mounting seat holes (not shown in the figure) are formed inside the bottom support 21; the arrangement direction of the mounting seat holes is in a radial arrangement for mounting the bottom end of the fireworks tube 23. In this way, the bottom end of the fireworks tube 23 can be better fixed, and then combined with glue for bonding, so that the fireworks tube 23 and the bottom support 21 are firmly combined.

[0042] Preferably, the bottom support 21 is a structure integrated with the holding arm 10 or a split structure adhesively bonded with glue.

[0043] Preferably, in this embodiment, the top support 22 is a wide strip with a certain thickness in an arc shape; the outer top surface of the top support 22 near the firing side has a bottom seal 222, and the inner bottom surface far from the firing side is open; the fixing holes 221 are formed in the bottom seal 222. The firing end of the fireworks tube 23 extends into the top support 22 through the opening of the inner bottom surface of the top support 22, then aligns with the fixing holes 221, and finally is fixed with glue; the firing end of the fireworks tube 23 can extend out of the fixing holes 221 or can be aligned with the fixing holes 221 but not extend out of the top support 22. Those skilled in the art can select according to needs as long as the firing end of the fixing column fireworks tube 23 is fixed and the firing and ejection of the fireworks are not affected.

[0044] Preferably, the width of the bottom support 21 is greater than the width of the top support 22. Relatively speaking, the fixing of the bottom end of the fireworks tube 23 is the main stress-bearing position.

[0045] Preferably, in this embodiment, it further includes a fixed spacer. The fixed spacer is in the shape of an arc-shaped sheet, and a plurality of holes 31 are formed in the spacer. The positions of the holes 31 correspond to the positions of the plurality of fireworks tubes 23; the holes 31 are semi-hole structures. Specifically, the fixed spacer can be made of plastic or paper. During use, the spacing of the holes 31 is determined according to the installation position of the fixed spacer. For example, if it is installed on one side close to the bottom end of the fireworks tube 23, the total length of the spacer is smaller and the spacing of the holes 31 is also smaller; conversely, the closer it is to the firing end of the fireworks tube 23, the larger the size of the spacer and the larger the spacing of the holes 31; the specific calculation method is calculated according to the size of the fan-shaped ring formed by the arrangement of the fireworks tubes 23. The structure of the semi-hole 31 is more conducive to the installation of the spacer.

[0046] Preferably, in a preferred embodiment, the fixed spacer 30 includes a first spacer 301 and a second spacer 302. The first spacer 301 is disposed in the middle of the fireworks tube 23; the second spacer 302 is disposed at the opening of the inner bottom surface of the top support 22.

[0047] Preferably, in a specific embodiment, in order to increase the number of fireworks tubes 23, a plurality of the fireworks tubes 23 can be arranged in a multi-layer structure, and the fireworks tubes 23 in each layer are arranged in a fan-shaped ring. For example, in this embodiment, an example of two layers with 10 fireworks tubes 23 in each layer is shown.

[0048] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present invention should be covered by the protection scope of the present invention.
