4. the connecting ring at the upper external thread end of the inserting pipe is embedded in the external thread pipe, and the inserting pipe and the external thread pipe can be rotatably connected at the moment; when the external threaded pipe needs to be rotated, the first internal thread sleeve is unscrewed, so that the connecting ring is not abutted against the limiting ring any more, and then the external threaded pipe can be rotated under the condition that the inserting pipe does not rotate, so that the external threaded pipe is prevented from rotating to influence the connection between the inserting pipe and the hose;

after the rotation of the external threaded pipe is finished, the first internal thread sleeve is screwed down to enable the connecting ring to be abutted against the limiting ring, and at the moment, the connecting gap between the inserting pipe and the external threaded pipe can be sealed, so that the gap between the inserting pipe and the external threaded pipe is prevented from being leaked;

5. the rubber sealing ring arranged on the limiting ring can be abutted against the connecting ring, so that the tight connection between the limiting ring and the connecting ring can be facilitated, and finally, the leakage of a gap between the plug-in pipe and the external threaded pipe can be further avoided;

6. after the inserting pipe is embedded into the hose, the second internal thread sleeve is rotated, so that the second internal thread sleeve drives the adjusting ring to approach to one side of the check ring by pushing the moving sleeve, and after the acute-angle end of the adjusting ring is inserted into the lower side of the check ring, the check ring made of elastic rubber material can be expanded, so that the check ring can tightly abut against the inner wall of the hose, and finally, the stable connection between the hose and the inserting pipe can be facilitated;

the adjusting ring is embedded in different positions of the lower side of the check ring according to the inner diameters of different hoses, so that the expanded outer diameter of the check ring can be adjusted, the check ring can be abutted against the inner walls of the hoses with different inner diameters, and stable connection between the splicing pipe and the hoses with different inner diameters can be facilitated;

7. the anti-slip stripes are arranged on the outer surfaces of the first internal thread sleeve and the second internal thread sleeve, and the friction force can be increased by the anti-slip stripes, so that the possibility of slipping during the rotation of the first internal thread sleeve and the second internal thread sleeve is reduced, and the stable rotation of the first internal thread sleeve and the second internal thread sleeve is facilitated;

8. when the splicing pipe is embedded into the hose and the check ring is abutted against the inner wall of the hose, the end part of the hose is also wrapped outside the adjusting ring and the snap ring, and then the plurality of clamping rods on the second internal thread sleeve are rotated, so that the rubber clamping blocks at the end parts of the clamping rods are embedded into the annular groove formed between the snap ring and the adjusting ring, and the hose can be pressed into the annular groove by the rubber clamping blocks, and finally, the stable connection between the hose and the splicing pipe can be facilitated;

9. when the rubber clamping block is embedded into the ring groove, the locking ring groove which is arranged on the adjusting ring and is positioned on the inner wall of one side of the ring groove is utilized, meanwhile, the rubber clamping block is integrally provided with the locking part, the locking part can be embedded into the locking ring groove, and finally, the hose can be tightly clamped in the locking ring groove, so that the stable connection between the hose and the splicing pipe is further facilitated;

10. utilize the locking annular groove all to be arc with the surface of locking portion, convex locking annular groove and locking portion surface can play the guide effect, make things convenient for the quick joint between locking annular groove and the locking portion.
