Preferably, referring to FIGS. 3 and 5 , the second connection portion 102 includes a first protrusion 1021, the first protrusion 1021 has an inclined surface section 1021a and a fixed section 1021c sequentially connected along the circumference of the water inlet end 10, the height of the inclined surface section 1021a increases sequentially along the circumference of the water inlet end 10 toward the fixed section 1021c, a groove 1021b is provided at one end of the inclined surface section 1021a close to the fixed section 1021c, and the fixed section 1021c extends along the axial direction of the water inlet end 10;

The third connecting portion 211 includes a second protrusion 2111, which has an axial section 2111a and a circumferential section 2111b which are connected to each other and extend axially and circumferentially along the sleeve 21 respectively. The axial section 2111a is clamped in the groove 1021b so that the circumferential section 2111b abuts against the inclined section 1021a and the fixed section 1021c.

In this embodiment, the sleeve 21 moves axially along the water inlet end 10, so that the sleeve 21 is sleeved outside the water inlet end 10. At this time, the axial section 2111a is located on the side of the lowest height of the inclined section 1021a, and the sleeve 21 rotates along the circumference of the water inlet end 10 toward the direction of increasing height close to the inclined section 1021a. At this time, the axial section 2111a moves along the inclined surface of the inclined section 1021a, moves and is clamped into the groove 1021b.
