At the same time, the outlet pipe 5 abuts against the second annular step surface 6112, thereby fixing the outlet pipe 5 inside the first outer pipe 1. At this time, the annular abutment part 44 abuts against the outer end face of the outlet end of the first outer pipe 1, thus forming the first assembly; then the second inner pipe 3 is inserted into the first outer pipe 1. The inner tube 4 is inserted into the outer tube 2 with its outlet facing the inlet. The inner tube 4 is rotated to connect the inner tube 4 and the outer tube 2 with threads, and its abutment part 44 abuts against the lower end face of the second connection part 21, thus forming assembly two. Assembly two is then fixedly connected to the valve body so that the first water passage 100 connects to the first water outlet and the second water passage 200 connects to the second water outlet. The fixing seat assembly 7 is then installed on the wall so that the outer tube 2 is fixed in the mounting hole 721. Assembly one and assembly two are then fixedly connected.

One end of the second inner pipe 4 is fixedly connected to the valve body. The inner pipe formed by the second inner pipe 4, the first inner pipe 3, and the outlet pipe 5 constitutes the first water passage 100, which forms the second water passage 200 with the outer pipe formed by the first outer pipe 1 and the second outer pipe 2. The outlet connector 6 is provided with a first outlet hole 611 and a second outlet hole 64. Thus, the first outlet, the first water passage 100, and the first outlet hole 611 constitute the first water path, and the second outlet, the second water passage 200, and the second outlet hole 64 constitute the second water path. The system forms a dual-waterway shower pipe. Because the inner wall of the second outer pipe 2 has a second connecting part 21, and the outer wall of the second inner pipe 4 has a second connecting mating part 43, the second connecting part 21 and the second connecting mating part 43 are threaded together. Furthermore, the outer wall of the second inner pipe 4 has an abutment part 44, which is adapted to abut against the lower end face of the second connecting part 21 along the water flow direction. This makes the second inner pipe 4 more securely fixed relative to the second outer pipe 2 along the water outlet direction, further strengthening the connection between the second inner pipe 4 and the second outer pipe 2. Compared to existing technologies, the entire inner pipe, especially the second inner pipe located at the outlet end of the valve body, is more secure. 4. In addition to the fixed connection with the valve body, a fixed connection with the second outer pipe 2 is added, which increases the structural strength of the entire pipeline and makes the fixation more reliable. This effectively avoids the abnormal noise caused by the water flow impact causing the inner pipe to vibrate or even hit the outer pipe when the pipeline is filled with water. Moreover, in this embodiment, the first inner pipe 3 and the first outer pipe 1 are connected to each other by setting the first connecting part 13 and the first connecting mating part 312 respectively, which increases the fixed connection between the first inner pipe 3 and the first outer pipe 1, further enhancing the structural strength of the overall pipeline, thereby better reducing the impact of water flow impact when the pipeline is filled with water.

[0068] In this embodiment, the first outer tube 1 and the second outer tube 2 are sealed and inserted together. The first inner tube 3 passes through the first outer tube 1 and is fitted with the second inner tube 4. The first inner tube 3 is threadedly connected to the first outer tube 1. The second inner tube 4 passes through the second outer tube 2 and is threadedly connected to the second outer tube 2. Therefore, the first outer tube 1 can slide relative to the second outer tube 2 and drive the first inner tube 3 to slide relative to the second inner tube 4, thereby realizing the lifting and lowering adjustment of the shower pipe. Moreover, the first inner tube 3 and the first outer tube 1, and the second inner tube 4 and the second outer tube 2 are detachably connected by the threaded connection, which is simple and firm.

[0069] In this embodiment, the water outlet connector 6 is threadedly connected to the first outer pipe 1, and the water outlet pipe 5 is sealed and inserted into the water outlet connector 6 and abuts against the second annular stepped surface 6112, which facilitates assembly.

[0070] In this embodiment, the first anti-rotation groove 6111 is adapted to be inserted into the tool to facilitate the installation of the water outlet connector 6.

[0071] In this embodiment, the height of the first outer tube 1 is freely adjustable through the fixed base assembly 7 to meet the user's needs.
