Through adopting above-mentioned technical scheme, when the fastening ring was screwed up gradually, the fastening ring made the slight deformation of tube-shape clamp ring emergence, played the effect of pressing from both sides tight plastic hose.

The utility model discloses further set up to: the outer diameter of the cylindrical clamping ring is gradually widened from the end far away from the internal thread A to the end close to the internal thread A.

By adopting the technical scheme, the outer diameter of the cylindrical clamping ring is gradually widened from front to back, so that the fastening ring is screwed more tightly, and the cylindrical clamping ring is also screwed more tightly for clamping the plastic hose.

The utility model discloses further set up to: the inner diameter of the fastening ring becomes gradually wider from the end away from the internal thread A to the end close to the internal thread A.

Through adopting above-mentioned technical scheme, make tighrening ring and the cooperation of tube-shape clamping ring use compacter.

The utility model discloses further set up to: and a hexagonal locking block is arranged on the outer ring of the cylindrical clamping ring provided with the internal thread A end.

Through adopting above-mentioned technical scheme, hexagon latch segment person of being convenient for with the spanner screw up the tube-shape clamp ring on the joint body.
