Diameter.
Preferably, the clip inner wall is equipped with the conical surface connecting with the second convex edge lower section, the wedge angle direction card of the conical surface
Bind round tail end.The conical surface forms the big space of small tail in clip inner wall, so that the interior claw being set in clip is to clip head end
When direction is mobile, the elastic slice on interior claw is pressurized along the conical surface and is deformed, and each elastic slice is tightened to center, the metal of elastic slice tail end
Card it is increasingly tighter block external water pipe.
Preferably, the metal inclined tab uniform intervals are arranged, the quantity of metal inclined tab is 12 ~ 20.Metal inclined tab
It is evenly spaced on the shape for forming similar gear sheet in clip outer wall with optimal number range, connect clip with outer retainer ring
Fastening.
Preferably, the metal inclined tab width and the ratio range of metal inclined tab spacing are 1:0.8 ~ 1.2.
Preferably, the metal inclined tab and the angular range of clip outer wall are 40 ° ~ 70 °.
Preferably, the depth of groove is less than the vertical range on metal inclined tab top and clip outer wall.It designs in this way
Purpose be to be embedded in metal inclined tab in the groove of outer retainer ring inner wall, the firmness that increase clip is connect with outer retainer ring.
Preferably, the interior claw, clip and outer retainer ring are cylinder.
The beneficial effects of the utility model are:
The external clamping type snapping quick coupling of the utility model is connected using external clamping type between clip and outer retainer ring, is avoided
Ultrasonic bonding mode bring rosin joint and welding slag problem, avoid wanting for the frequent replacement stationary fixture in production process
It asks, improves product quality stability and product processing efficiency；For the metal inclined tab of clip outer wall similar to gear plate shape, stress is equal
It is even, so that clip is connect fastening with outer retainer ring；External water pipe is directly inserted into interior claw and realizes fixation, easy to operate, and by
In the structure of interior claw and clip inner wall, interior claw is higher to the firmness of the connection of external water pipe.
