In this state, as in the case of the Nichrome wire R, by setting six flying fireworks 7 and igniting the ends of the continuous ignition fuse D with a match or the like, the fire propagates through the continuous ignition fuse D. ,
Fire is sequentially transmitted to the fuses 7b of the six flying fireworks 7, and the flying fireworks 7 are continuously emitted. By the way, compared with the case where the Nichrome wire R is used, it is necessary to set the continuous ignition fuse D every time, but after igniting the end of the continuous ignition fuse D, You can enjoy a different way of playing from when you use the Nichrome wire R in that the time it takes to launch the flying fireworks is shortened.

Next, the procedure and mode of adjusting the flight direction of the flying fireworks 7 will be described. First, the intermediate support plate 17 is adjusted to an appropriate height in accordance with the length of the bamboo strip 7c in the flying fireworks 7, and each outer lower support hole 21 is positioned directly below the upper support hole 11 with a screw N ₂ To fix. Then, after the bamboo strip 7c of the flying fireworks 7 is passed through the upper support hole 11 and then through the outer lower support hole 21 of the intermediate support plate 17 corresponding thereto, the fire wire 7b of the flying fireworks 7 which is bent in advance is the nichrome wire. Set 6 flying fireworks 7 so that they will be placed on top of R. In such a state, the entire portion of the flying fireworks 7 can be detached upward by the portion where the fuse 7b of the flying fireworks 7 contacts the nichrome wire R and the portion where the lower end of the tubular body 7a contacts the upper surface of the support body 4. You will be supported. In this state, if the squib 7b of the flying fireworks 7 is ignited by the igniter 5 in the above-described manner, the six flying fireworks 7 are vertically fired at substantially the same time or continuously. Further, as shown in FIG. 7 (b), the flying fireworks 7 are set in the vertical direction, and the intermediate support plate 17 is rotated about the support pillars 3 to support the bamboo sticks 7c in the flying fireworks 7. Since the conical notch 23 formed below the support body 4 can freely move around the portion in contact with the upper surface of the body 4 as a fulcrum, the six flying fireworks 7 can be moved according to the turning distance thereof. Slightly tilted to the vertical. When the squib 7b of the flying fireworks 7 is ignited in such a state, the six flying fireworks 7 are fired upward by adding the moving components in the tangential direction of the circular support 4 to each other. Furthermore, when the bamboo fireworks 7c are inserted into the inner lower support holes 22 of the intermediate support plate 17 when setting the flying fireworks 7, the flying fireworks 7 are perpendicular to the tangential direction of the circular support 4. Orientation, and tends to tilt somewhat towards the outside of the support 4. Therefore, if the squib 7b of the flying fireworks 7 is ignited in such a state, the flying fireworks 7 fly in an orbit spreading like a fountain. Furthermore, if the bamboo support 7c of the flying fireworks 7 is inserted into the inner lower support hole 22 of the intermediate support plate 17 and the intermediate support plate 17 is moved up and down as shown in FIG. 7 can change the inclination of the direction perpendicular to the tangential direction of the support 4 in various ways, and in such a state, the intermediate support plate 17 is attached to the support 3
By rotating about, the flying fireworks 7 can be directed in various directions. Therefore, by rotating the intermediate support plate 17 having such a flight direction adjusting function to the left or right or sliding it up or down, the flying fireworks 7 can be operated in such a state.
You can make the flying fireworks 7 fly in various orbits by firing. Further, as the ignition mechanism, in addition to moving the ignition device 5, the ignition device 5 may be fixed and the flying fireworks 7 may be moved to ignite the squib 7b. Although all of the embodiments described above include the ignition device 5, it does not matter if the ignition device 5 is removed and the squib 7b of each flying fireworks 7 is manually ignited.

<Effect of the device> The flying fireworks launching device 1 of the present invention can emit a plurality of flying fireworks at the same time or continuously, and the flight direction of the flying fireworks 7 can be adjusted. You can play different flying fireworks. Moreover, in the case of the structure in which the ignition wire 7b of the flying fireworks 7 is indirectly ignited by the nichrome wire R or the like, it is possible to play safely as compared with the case of directly igniting the ignition wire by a match or the like.
