the inner tube opening 101 is provided with a first external thread, the outer tube opening 201 is provided with a first internal thread matched with the first external thread, the fastener A102 is provided with a second internal thread, and the fastener B202 is provided with a second external thread matched with the second internal thread.

In this embodiment, the thread direction between the first external thread and the first internal thread is opposite to the thread direction between the second external thread and the second internal thread.

The inner tube opening 101 and the outer tube opening 201 are connected by a first internal thread and a first external thread, the fastener a102 is slid into contact with the fastener B202, then the fastener B202 is rotated, at which point the fastener a102 continues to slide on the ram 103 towards the fastener B202 under the action of a second internal thread and a second external thread until the fastener a102 reaches the end of the ram 103, at which point the fastener a102 is fixed with the fastener B202.

Therefore, to open the inner tube opening 101 and the outer tube opening 102, the fastener B202 needs to be rotated first, so that the fastener B202 is separated from the fastener a 102. So that the high-pressure pipe is firmly connected.

Such a design also allows for the splicing of multiple high pressure tubes to one another, as shown in fig. 1.

Further, the outer wall of the inner tube head 1 is provided with a first convex ring 105, and two sides of the first convex ring 105 are provided with first clamping grooves; the outer wall of outer tube head 2 is equipped with second bulge loop 205, just second bulge loop 205 both sides are equipped with the second draw-in groove.
