The evagination pipe is furnished with that the cunning for covering the admittedly described flaring tube head periphery is fixed or the evagination pipe is equipped with being used for
The solid flaring tube head periphery of set and the cunning for resisting the basal disc are fixed, and the fixed inner circumferential of cunning is formed with for preventing from the expansion
Mouth tube head moves back de- multiple tracks ring slope；
Evagination pipe periphery is by together or the elastic washer that is respectively configured of multiple tracks outer groove arranged side by side and the flaring
The sealing of tube head inner circumferential.Sliding clamping method is: first by the flaring tube head of evagination pipe indentation butt tube, resisting flaring tube head front end
The basal disc；It slides to again the cunning of inner sleeve butt tube is fixed and resists the basal disc.It is hinged with fast and easy, and adhesion
The good advantage of energy.
As optimization, when the outer groove is one, positioned at the front end of the evagination pipe；When the outer groove is multiple tracks,
It is located at the front end of the evagination pipe, other distributions successively spaced inwardly together；The other parts periphery of the evagination pipe is formed with institute
State multiple tracks ring slope.
As optimization, evagination pipe front end is formed with the outer groove for being furnished with elastic washer together, the evagination pipe
Periphery is formed with multiple tracks ring slope；Or front and rear part periphery of the evagination pipe in addition to middle part is formed respectively with multiple tracks ring arranged side by side
Slope, preferably evagination pipe middle part periphery are formed with the flat-top ring concordant with ring slope flash；Or in the middle part of evagination pipe and rear portion
Periphery is formed with multiple tracks ring slope arranged side by side, and the preferably described evagination pipe front periphery is formed with the flat-top ring concordant with ring slope flash；
Or evagination pipe front end be formed respectively with middle part together be furnished with the outer groove of elastic washer, it is described outer
Front and rear part periphery of the convex pipe in addition to middle part is formed respectively with multiple tracks ring slope arranged side by side.
As optimization, what the land rank being formed between the evagination pipe base portion and basal disc front side was configured by outer groove
Elastic washer and the fixed front end inner circumferential sealing of the cunning cooperate.
As optimization, the fixed front end inner circumferential of cunning is formed with the concave ring stage matched with the land rank and its elastic cushion snare.
As optimization, the fixed inner circumferential of cunning by together or the elastic washer that is respectively configured of multiple tracks inner groove arranged side by side with
The flaring tube head periphery sealing that evagination pipe periphery set is matched.
As optimization, inner groove inner circumferential front fixed positioned at the cunning when being one.
As optimization, the fixed front end inner circumferential of cunning is formed with the concave ring stage matched with the land rank and its elastic cushion snare；
The concave ring stage is the inner groove backward；The inner groove is moved back relative to the flaring tube head for anti-on-slip to be fixed backward
De- multiple tracks ring slope.
As optimization, the fixed middle part periphery of cunning is formed with annular groove；The connector be elbow joints, threeway, four-way,
To any multiterminal head of Threaded Connector Coupling, reducer union.The fixed periphery of cunning is formed with the arrow for being directed toward sliding tight direction.
As optimization, multiple tracks ring slope is the forward direction ring slope that evagination pipe periphery is formed with that high front side is low on rear side of multiple tracks；It is described
Multiple tracks ring slope is the forward direction ring slope that the fixed inner circumferential of the cunning is formed with that low rear side is high on front side of multiple tracks.The front and back forward direction Huan Po described in per pass
The bottom concordant with its preceding low side is all formed with to rise as high as the banks, behind forward direction ring slope described in per pass flash and the bottom rise as high as the banks between be formed with radial hang down
Straight wall.
Sliding clamping method is: first by the flaring tube head of evagination pipe indentation butt tube, resisting flaring tube head front end described
Basal disc；It slides to again the cunning of inner sleeve butt tube is fixed and resists the basal disc.
After adopting the above technical scheme, tightly inside and outside seal nipple is hinged with the fast ski-running of the present invention with fast and easy, and touch
The good advantage of performance.
