[0022] Please see Figure 1-2 A semi-circular frame for launching special effects fireworks includes a base 1. The base 1 has a semi-circular frame 2 fixedly connected to its top. A connecting frame 3 is fixedly connected to the outside of the semi-circular frame 2. Nine equally spaced, circular insertion slots are provided on the side of the connecting frame 3 away from the semi-circular frame 2. Five equally spaced, circular launching components 4 are movably connected to the outside of the connecting frame 3. Each launching component 4 includes a fireworks launching tube 41. Five equally spaced, circular fireworks launching tubes 41 are inserted into the outside of the connecting frame 3. The front of the connecting frame 3... The side wall is threaded with five positioning bolts 42 that are evenly distributed in a ring. The front side wall of the connecting frame 3 is provided with nine threaded limiting holes that are evenly distributed in a ring. The threaded limiting holes are connected to the insertion slots and are adapted to the positioning bolts 42. The five positioning bolts 42 are threadedly connected to the front side wall of the five fireworks tubes 41 respectively. The inner walls of the fireworks tubes 41 and the connecting frame 3 are provided with matching lead wire holes. The outer side of the connecting frame 3 is provided with a lead wire groove that extends in a ring direction and is connected to the lead wire holes of each fireworks tube 41.

[0023] Two adjustable support components 5 are movably connected to the left and right sides of the inner top wall of the base 1 and are symmetrically distributed front and back. The bottom of the four adjustable support components 5 extends to the bottom of the base 1. Each adjustable support component 5 includes a connecting cavity 51. Two connecting cavities 51 are opened on the left and right sides of the base 1 and are symmetrically distributed front and back. A threaded rod 52 is rotatably connected to the inner top wall of each connecting cavity 51. A threaded cylinder 53 extending to the bottom of the base 1 is threadedly connected to the outside of the threaded rod 52. The inner bottom wall of the connecting cavity 51 is connected to a through hole opened on the base 1 and adapted to the threaded cylinder 53. A support foot 54 is fixedly connected to the bottom of the threaded cylinder 53. A rubber anti-slip pad with a thickness of two centimeters is fixedly connected to the bottom of the support foot 54. A threaded mounting hole is opened inside the support foot 54. A limiting plate 55 located inside the connecting cavity 51 is fixedly connected to the outside of the threaded cylinder 53.

[0024] It is worth noting that the standard parts used in this application can all be purchased from the market, and the specific connection methods of each part are all connected by conventional means such as bolts, rivets, and welding that are mature in the prior art. Furthermore, the machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.

[0025] In summary, the semi-circular frame for this special effects fireworks display, by incorporating the firing assembly 4, allows for the addition of fireworks tubes 41 when the number of tubes needs to be increased. These tubes 41 are inserted into the insertion slots and secured by the positioning bolts 42 and threaded limiting holes. Conversely, when the number of tubes needs to be reduced, the positioning bolts 42 are rotated to unscrew them, and the tubes are then pulled out of the insertion slots, thus reducing the number of tubes and meeting the practical needs of the staff. The device's practicality has been improved by setting an adjustable support component 5. The rotating support leg 54 drives the threaded cylinder 53 to rotate. With the cooperation of the threaded cylinder 53 and the threaded rod 52, the support leg 54 moves down, and the position of the four support legs 54 can be adjusted to adapt to uneven ground. This further improves the device's practicality and solves some defects of the existing semi-circular frame for special effects fireworks. For example, the number of firing tubes is fixed and cannot be increased or decreased according to usage needs, which cannot meet the user's needs. Also, the frame cannot be placed stably when the ground is uneven.
