As an implementation mode, corresponding to the installation position of the water pipe clamp 194, a sheath can be arranged on the water pipe, the outer diameter of the sheath is required to be larger than the diameter of the installation space, the sheath is fixedly matched with the water pipe clamp 194, abrasion of the water pipe is reduced, meanwhile, the water pipe clamp 194 has the identification function of the installation position, and when the water pipe clamp is installed, whether the position of the sheath corresponds to the water pipe clamp 194 or not can be determined, so that whether the installation of the water pipe is wrong or not can be determined. The sheath can be made of polyethylene material and is arranged on the water pipe through a thermal contraction process. The water pipe clamp 194 may be made of plastic. The water pipe is fixed through the water pipe clamp 194, so that the manual assembly cost is effectively reduced, the assembly difficulty is reduced, and meanwhile, the water pipe clamp 194 can be made of plastics, and the cost control is facilitated.

It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
