Preferably, described nozzle body is corresponding with front intersegmental part conically, hemispherical or half elliptic.
This shape improves the first anti-falling pipe, the second anti-falling pipe and the laminating degree between nozzle body and front intersegmental part.
Preferably, the edge of the first described anti-falling pipe and the flared end of the second anti-falling pipe is set to crimping, and crimping is socketed elastic ring.
Can be fitted on inwall around crimping, crimping also can be pushed down elastic ring and be fitted on inwall, further increases the sealing of sealing between the first anti-falling pipe and nozzle body inside and the second anti-falling pipe and front intersegmental part.
The beneficial effect of the invention:
First anti-falling pipe of the present invention and the second anti-falling pipe are threaded togather, again they are agreed with respectively the inside being placed on nozzle body and leading portion, first anti-falling pipe and the second anti-falling pipe are under the impact of high speed abradant jet, the first anti-falling pipe and nozzle body inside is made to fit tightr, better tightness, second anti-falling pipe and front intersegmental part, fit tightr, better tightness, structure is simple, improve the bonding strength between nozzle and pipe joint and sealing, ensure that cutting power and cutting speed reach the requirement of work, workpiece is without the need to carrying out secondary cut processing, otch one-shot forming, good manufacturability is aesthetic in appearance, reach the requirement of high precision processing.
