Preferably, the upper end and the lower end of the two annular blocks are fixedly connected with a plurality of rollers, and the rollers are respectively in rolling connection with the inner top and the inner bottom of the corresponding annular groove.

Preferably, the cross section of the annular groove and the annular block are both T-shaped.

Preferably, the rubber hose comprises polar rubber, a pressure-resistant rubberized fabric rubber tube is arranged at the upper end of the polar rubber, a steel ring is arranged on the pressure-resistant rubberized fabric rubber tube, and a galvanized soft film is arranged at the upper end of the pressure-resistant rubberized fabric rubber tube.

Preferably, the outer walls of the two connectors are provided with first thread layers, and the inner walls of the two connectors are provided with second thread layers.

Preferably, the two first thread layers are in threaded connection with the corresponding second thread layers.

Compared with the prior art, the device has the advantages that:

compared with the prior art, the flexibility of the rubber hose enables the position of the pipe head interface to be changed in any direction to change the inherent, directional and complicated phenomena of pipe construction, so that the material is saved, the construction efficiency is greatly improved, and the appearance is ensured;

compared with the prior art, through setting up of locating lever and locating hole for when tube head and connector are connected, ensure that the tube head can not appear the condition of smooth silk with the connector when rotating, thereby ensure the stability when tube head and connector are installed.
