[0032] Embodiment 2, based on Embodiment 1, in combination with Figure 3 and Figure 4 Description:

[0033] The pressing and rotating lock sleeve 4 comprises: a lock plate part 41, a fastening part 42, and a connecting part 43. The lock plate part 41, the fastening part 42, and the connecting part 43 are of an integral structure. The integral structure design makes the lock sleeve have strong integrity, not easily loosen or fall off, thus improving the reliability and safety of the connection.

[0034] The lock plate part 41 is arranged on one side of the fastening part 42, and the connecting part 43 is arranged on the other side of the fastening part 42. The lock plate part 41 is used in cooperation with the water pipe connection seat 5, and the connecting part 43 is connected to the telescopic pipe 3. The fastening part 42, as the transition part between the lock plate part 41 and the connecting part 43, can provide additional support and fixation functions, ensuring the stability and durability of the entire lock sleeve.

[0035] There are three groups of the lock plate parts 41, and the three groups of lock plate parts 41 are evenly arrayed at intervals. The interval angle of the three groups of lock plate parts 41 is 120 degrees. The 120-degree interval makes the lock plate parts evenly distributed on the circumference. In this way, it can be ensured that on the 360-degree circumference, each lock plate part can bear an equal responsibility area, thus realizing an even load distribution. The evenly distributed lock plate parts can enhance the structural stability because each lock plate part can provide support, reducing the stress concentration problem caused by concentrated loads.

[0036] One side of the lock plate part 41 is provided with a fitting surface 411, and the fitting surface 411 is used for pressing the sealing ring 6 arranged on the water pipe connection seat 5. Thereby improving the sealing performance.

[0037] An anti-slip pattern 421 is provided on the outer side of the fastening portion 42. With such a setting, it is convenient for the staff to rotate the fastening portion 42.
