    Abstract: Disclosed is a telescopic water pipe, comprising: an elastic inner pipe for allowing a liquid to pass therethrough, the elastic inner pipe having a contraction length and an extension length under the action of the pressure of the liquid passing therethrough; and a braided layer wrapped on an outer circumferential surface of the elastic inner pipe; wherein the elastic inner pipe and the braided layer form together a first telescopic pipe body, the first telescopic pipe body expanding and contracting with the expansion and contraction of the elastic inner pipe, and its outer diameters at the contraction length and at the extension length being close to the outer diameters of the elastic inner pipe at the corresponding lengths. Therefore, the braided layer can expand and contract in synchronism with the elastic inner pipe while protecting the elastic inner pipe from being pierced by external sandstone and burr, and the elastic inner tube is not worn out, thereby prolonging the service life of the first telescopic pipe body. Since the braided layer is woven seamlessly on the elastic inner pipe, the amount of use of the braided layer is saved, and the obtained first telescopic pipe body has a small volume, a small occupied space, a light weight, and also an unrestricted length.
