[Prior art]

Conventionally, firecrackers have the concept of being used as a party in the room or as a toy in the home, and if it is used indoors, it is a condition that the ejected jet does not fly too far so as not to be scattered. I also liked that the length of the tape itself is about 2 to 3 meters.

In other words, the conventional firecracker is in a conical hollow body 33 having an openable firing part 32 occluded in a plurality of protruding pieces 31 provided before use, as shown in FIG. The extruding force generated by the explosion of the gunpowder 34 provided is transmitted to the circular pressure receiver 35 made of paper, which is formed of paper or the like, and is installed between the firing unit 32 and the gunpowder 34, and The pressure receiver 35 releases the launch unit 32 of the electric body 33 and is discharged to the outside from the launch unit 32, and at this time, the pressure receiver 35 and the electric launch unit 32 The jet 36, such as a small wound tape or a piece of paper, stored in between was air-launched from the launching unit 32.

[Problems that the invention tries to solve]

However, the conventional firecrackers are not particularly problematic in use in a narrow room, but, for example, the distance to be thrown away for use in cheering for outdoor equipment such as soccer or football, or for playing various music shows in a large hall, etc. 3m and the length of the tape is also very poor, 1 ~ 2m.

The present invention has been made in order to solve the above problems, and even when used in cheering or outdoor halls of outdoor ball games, the shape of the ejection of the tape, etc. without any inferiority, that is, the distance thrown away dozens of meters, the length of the open tape It is aimed at providing a very safe firecracker that can be discharged nicely to be tens of meters long.

[Means to solve the problem]

The present invention has been made to solve the above-described problems, and the technical means for solving the above-mentioned problems is, at one end (2) inside the ordinary body (3) in which both ends (1) and (2) are opened. Explosion of the gunpowder (9) to which the pulling string (8) to be exposed and the gunpowder (9) of the gunpowder (9) prevents exposure of the gunpowder (7) and the electric gun (9). Between the ejection force 5 and the inserted firecracker which is air-launched at the other end 1 between the pressure receiver 6 and the other end 1 of the ordinary body 3 and the pressure receiver 6 which are extruded. In addition, the electric body 3 has a hollow cylindrical shape, and the pressure receiver 6 slides freely on the inner wall of the body 3 in a compressed state, and the body ( One end 2 of 3) is in close contact with the electric fastener 7, and the other end 1 is in close contact with the lid 4.
