When specifically used：During water spray, water valve is made, water is flowed into from guide base 10 and the space of annular groove 5
Sprayed in the internal thread outer wall 2 and from port, this is device in straight mouth water spray.Because the interface body 1, external screw thread are sprayed water
Pipe 3 and guide base 10 are fixed as one structure, so when fireman's manual rotation interface body 1, external screw thread sparge pipe 3 and lead
Base 10 is flowed equally to rotate, when the annular seal convexity structure 12 in guide base 10 withstands soft sealing ring 13, water spray
Stop, completing water spray process.
Embodiment 2
As shown in figure 3, stealthy fire-fighting lance improves place relative to embodiment 1 and is in embodiment：Internal thread outer wall 2 can
Multiple for fixed annular groove to set, each annular groove is interior to set one or more metal wire, in the present embodiment,
Annular groove number is 4, and diagonally disposed, and the fixed component used in each annular groove is 3 metal lines.
Embodiment 3
As shown in Fig. 4,5,8, stealthy fire-fighting lance improves place relative to embodiment 1 and is in the present embodiment：The ring
Circular hole chassis 14 is inserted with connected in star 5, T fonts bolt 15 is plugged in the external screw thread sparge pipe 3, and the bolt 15 is passed through
The center hole on the circular hole chassis 14 is simultaneously fixed on the circular hole chassis 14 by nut 16, and the bolt end face 17 is located at
The outside of interface body end face 18, and the diameter of bolt end face 17 is less than the diameter of the inner circular groove of interface body 1,
The bolt end face 17 is provided with inside soft sealing structure 19, the interface body 1 close to the side of external screw thread sparge pipe 3 and set
It is set to arcuation necking stereochemical structure 20.The external screw thread sparge pipe 3 fixes (glue is solid) on the end face of the interface body 1.This
The water gun structure of embodiment optimizes the inner connecting structure of interface body 1, and the internal structure of interface body 1 is arranged to
Arcuation necking stereochemical structure causes water flow jet more smooth.
When specifically used：During water spray, water valve is made, water is sprayed into from the circular hole on circular hole chassis 14, by described outer
Screw thread sparge pipe 3 sprays from the gap of bolt end face 17 and body end face 18, and this is device in flower-shaped water spray.Because described connect
Mouth body 1 is the structure that is fixed as one with external screw thread sparge pipe, and bolt 15, circular hole chassis 14 and internal thread outer wall 2 are structure as a whole.
So when fireman's manual rotation interface body 1, external screw thread sparge pipe 3 equally rotates, now bolt 15, the and of circular hole chassis 14
The integrative-structure of internal thread outer wall 2 is moved backward relative to interface body 1.When the arc of arcuation necking stereochemical structure 20 during this
When vertex of surface touches soft sealing structure 19, water spray stops, and completes water spray process.
Embodiment 4
As shown in fig. 6, stealthy fire-fighting lance improves place relative to embodiment 3 and is in the present embodiment, ball bearing 21
