When the external connecting pipe 7 is rotated counterclockwise, when the end of the L-shaped insert block 10 rotates to the limit in the rotation groove 12, the external connecting pipe 7 is released, and the elastic force of the first spring 15 drives the fixing rod 14 and the fitting disc 9 to rebound, so that the end of the L-shaped insert block 10 is stuck in the clamping groove 13. At this time, the insertion pipe does not come out, thus completing the installation and fixation of the external connecting pipe 7. When the external connecting pipe 7 is installed, it will squeeze the top of the vertical rod 18, causing the vertical rod 18 to move downward. The vertical rod 18 drives the bottom block 19 to move downward, and the bottom block 19 stretches the second spring 20, so that the bottom block 19 abuts against the top of the bottom plate 1. During use, the water inlet pipe 3 is connected to the external water delivery pipe.
