[0012] Furthermore, the sleeve is fitted onto the outside of the water outlet pipe and is movably connected to the water outlet pipe. One end of the outside of the water outlet pipe extends to the center of the connection between the sleeve and the nozzle. The inside of the nozzle is in contact with the outside of the water outlet pipe. The inner diameter of the nozzle is smaller than the inner diameter of the sleeve.

[0013] By adopting the above technical solution, the water outlet pipe can directly contact the inside of the nozzle, allowing the water flow to enter the nozzle immediately and improving the efficiency of water spray cleaning.

[0014] Furthermore, the retaining ring engages inside the retaining groove and is rotatably connected to the retaining groove. The outer side of the retaining ring and the inner side of the retaining groove are in contact with each other. The first retaining seat and the second retaining seat both adopt a semi-circular structure. The first retaining seat and the second retaining seat are the same size and have the same specifications. The limiting rod and the limiting groove are engaged and connected. The bolt and the threaded hole are threadedly connected.

[0015] By adopting the above technical solution, the retaining ring on the outside of the sleeve is clamped by two sets of semi-circular retaining seats. At the same time, the sleeve can rotate inside the retaining seat through the retaining ring to adjust the angle. The structure can be disassembled and installed by bolts, which is convenient for operation and use.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] The system employs a sleeve, a retaining ring, a retaining seat, and bolts. A sleeve is added to the outside of the outlet pipe, along with a retaining ring and a retaining seat that works with the retaining ring. This allows the angle of the sleeve to be adjusted by rotating between the retaining ring and the retaining seat. There are two sets of retaining seats, which can be disassembled and installed separately using bolts. The sleeve can be removed at any time for cleaning or replacement, resulting in a convenient user experience. Attached Figure Description
