An insert block 324 is fixedly provided at the end, and the insert block 324 is movably connected with the connecting and fixing flange 2. A dial plate 325 is fixedly provided on the upper end of the insert block 324. By toggling the dial plate 325, the insert block 324 is driven to compress the spring 323, and the outer flange 31 is rotated to make it threadedly connected with the connecting and fixing flange 2, and then the dial plate 325 is loosened, the spring 323 is reset and pushes the insert block 324 to make it fit and connect with the connecting and fixing flange 2 and fix it, thereby completing the connection and fixation of the pipeline, and the operation process is convenient and quick.

[0024] Combination Figure 3, the outer flange 31 includes a threaded cap 311 that is threadedly and movably connected to the connecting and fixing flange 2. One end of the threaded cap 311 is fixedly provided with an angle ring 313. An inner side of the angle ring 313 is fixedly provided with a sealing ring 314. An outer side of the sealing ring 314 is movably provided with a tightening ring 312. By screwing the threaded cap 311 to be threadedly connected to the connecting and fixing flange 2, the connection at the pipe joint is realized. The sealing effect at the joint is improved by the sealing ring 314 provided on the inner side of the angle ring 313. The tightening ring 312 provided on the outer side of the sealing ring 314 continuously generates a centripetal binding force on the sealing ring 314, further improving the sealing effect of the sealing ring 314.

[0025] Combined with Figure 2 , the water delivery pipe 1 includes a pipe one 11. A pipe two 12 is fittingly and movably arranged inside the pipe one 11. A through hole one 13 is opened on an outer surface of the pipe one 11. A slot one 14 is opened on an outer surface of the pipe two 12.

The opening of the slot two 215 enables it to cooperate with the plug one 324 to fix the connecting and fixing flange 2 and the connecting and movable flange 3 after tightening to prevent loosening.

[0028] Combined with Figure 6, the elastic plug 23 includes a spring three 231 fixedly connected to the surface of the through hole two 212. A limiting plate 232 is fixedly arranged at the lower end of the spring three 231. An insertion block two 233 is fixedly arranged at the lower end of the limiting plate 232.

Lift the limiting plate 232 to compress the spring three 231, and then align the insertion block two 233 with the through hole one 13 and the slot one 14 and release the limiting plate 232. The spring three 231 resets and pushes the limiting plate 232 and the insertion block two 233 downward, so that the insertion block two 233 passes through the through hole one 13 and contacts and fixes with the slot one 14, preventing displacement between the device and the pipeline, thereby invalidating the connection.
