[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the present invention, since the surface of the end of the tube body is provided with an external tube thread, the inner end of the nut is also provided with an internal thread sleeve. The surface of the tube body is connected through the external tube thread and the internal thread sleeve provided inside the nut, thereby forming a first tight connection, so that the tube body and the intermediate piece are tightly connected and not easy to fall off.

[0016] In the utility model, a limiting plate and a sealing ring are provided on the outer surface of the fixing part, and the sealing ring fits tightly against the inside of the nut to form a seal. A sealed environment of the pipe and the connector is formed by the sealing assembly, so that the inside of the pipe body is sealed to avoid accidents such as leakage.

[0017] In the present invention, a plurality of spring sheets are fixed on the outer surface of the fixing member and engaged with the inside of the tube body, thereby achieving a second tight connection between the intermediate member and the tube body, strengthening the tightness of the connection between the tube body and the intermediate member, and providing a tighter connection relationship.
