Claims

[Scope of utility model registration request]

The end face has a conical convex shape, and an annular groove is formed on this end face, and the inside of the annular groove and a liquid passage hole provided at the center of the base and communicating with the fire extinguishing liquid supply path are communicated with each other by a communication hole. and a base body that allows the fire extinguishing liquid sent through the fire extinguishing liquid supply channel to be fed into the annular groove, and a cap nut shape that is attached to this base body and is in close contact with the end surface of the base body. A plurality of circular recesses into which blade pieces can be freely fitted are formed in a portion of the conical cover plate portion facing the base and aligned with the annular groove, and continuous to the circular recesses, A cover with a spout that spouts out the extinguishing liquid after it has passed through the blade in a divergent shape, and blades that are the same shape and are twisted at equal angles on the peripheral edge of a disk that is held between the cover and the base. A wide-angle fire extinguishing nozzle consisting of a plurality of blade pieces.
