[0041] Preferably, when the rotating ring 421 rotates, the arc-shaped groove 422 rotates with it, and in this process, the arc-shaped groove 422 extrudes the control rod 423, and then drives the fixing rod 424 on the control rod 423 to move in the storage groove 425, by controlling the movement of multiple fixing rods 424 to the inside, and then the fixing rod 424 is fixed in the connecting head 412 to complete the connection with the mounting head 411.

[0042] Further, the mounting part 4 further comprises an extrusion part 43, which comprises a connecting groove 431 arranged on the connecting head 412, a long rod 432 arranged on the connecting groove 431, a control ring 433 arranged on the long rod 432, an inclined groove 434 arranged on the control ring 433, an extrusion inner thread ring 435 arranged on the water pipe 321, and an extrusion rod 436 arranged on the extrusion inner thread ring 435.

The extruded rods 436 moving to the right will cooperate with the inclined groove 434 opened at the left end of the control ring 433 and extrude the inclined groove 434, thereby pushing the control ring 433 to rotate. The control ring 433 will synchronously drive the rotating ring 421 inside the connecting head 412 to rotate when it rotates. At the same time that the rotating ring 421 rotates, the arc-shaped groove 422 opened in it will also rotate. The rotating arc-shaped groove 422 will extrude the control rod 423 placed in the groove, thereby driving the fixed rod 424 installed on the control rod 423 to move in the storage groove 425 opened in the connecting head 412. Through the continuous extrusion of the arc-shaped groove 422 on the control rod 423, the multiple fixed rods 424 will move inwardly and shrink. Finally, these inwardly shrinking fixed rods 424 will firmly fix the connecting head 412 inside the mounting head 411, completing the installation and fixation of the mounting head 411 and the connecting head 412.
