[0040] In order to improve the sealing performance of the connection between the connector 20 and the connecting pipe, corrugated elastic ridges 22 are evenly distributed on the surface of the mating portion 21 of the connector 20. When the connector 20 is mated with the connecting pipe, the elastic ridges 22 can be deformed and filled in the gap between the connector 20 and the connecting pipe, thereby improving the sealing performance and preventing medium leakage.

[0041] In order to facilitate the disassembly and assembly of the connecting member 20, a positioning groove 31 is provided in the medium channel 11, and the positioning grooves 31 are evenly distributed. The surface of the connecting member 20 is provided with a positioning portion 23 corresponding to the positioning groove 31. The number and shape of the positioning grooves 31 are set according to actual conditions. During installation, it is only necessary to align the positioning portion 23 with the positioning groove 31 and then insert it into the medium channel 11 to achieve the installation of the connecting member 20. The surface of the connecting member 20 is provided with a mounting portion 25, and a sealing member 28 is installed on the mounting portion 25. The sealing member 28 can be a sealing ring or other sealing components. The setting of the sealing member 28 improves the sealing effect.

The locking block 19 It can move axially in the movable groove 34 without colliding with the movable groove 34. At the same time, an adjustment groove 29 is provided on the main body 10, and the adjustment groove 29 is arranged opposite to the movable groove 34. When the end sleeve 14 needs to be replaced or installed, the adjusting rod 18 is rotated to adjust the locking block 19 to the adjusting groove 29. Only then can the end sleeve 14 be installed or removed. The connecting pipe and the connecting piece 20 are matched, and the adjusting rod 18 is rotated using existing tools. The adjusting rod 18 is rotated to drive the locking block 19 to move toward one end close to the connecting pipe until the surface of the locking block 19 is against the surface of the connecting pipe, thereby locking the connecting pipe.
