Referring to fig. 2, a deformation chamber 41 is formed in the elastic ring 4, and the deformation chamber 41 is filled with an extrusion gas, which may be air or oxygen. The inner ring side wall of the elastic ring 4 is abutted against the outer side wall of the insertion section 2 by extruding gas, and the outer side wall of the elastic ring 4 is abutted against the inner side wall of the connection section 3, so that the sealing efficiency is further improved. The elastic ring 4 is made of a flexible material and can generate a certain deformation amount, and in this embodiment, the elastic ring 4 is made of a polyamide fabric, so that the elastic ring 4 is not easy to break.
Referring to fig. 2, a first clamping ring 5 and a second clamping ring 6 are arranged in the connecting section 3, the first clamping ring 5 and the second clamping ring 6 are respectively positioned at two sides of the elastic ring 4, and the first clamping ring 5 is positioned at one side of the elastic ring 4 away from the pipe orifice of the connecting section 3.
