[0023] The through-body and the outer shell are connected and fixed by screw threads and sealed by an O-ring;
[0024] The nylon hose is connected through the bamboo-jointed inverted teeth of the clamp ring, and the nylon tube and the O-ring are axially sealed.
[0025] The material of the two pipes 1 is nylon;
[0026] Among them, nylon tubes are used, which have good physical, chemical and mechanical properties: wear resistance, smooth surface, soft, easy to bend, easy to install, simple processing. At the same time, they have rigidity. When a certain shape is required, they can be made into various shapes like metal tubes, and do not require complex equipment and tooling; they can resist corrosion from many chemical substances; they are dimensional stable; they have low permeability; they are insulated; they have a long service life and good temperature resistance.
[0027] The ends of the two pipes 1 extend to the middle of the inner cavity of the through-body 3, and the two pipes 1 are connected to the inner cavity of the through-body 3;
[0028] So that the solutions in the two pipes 1 can flow.
[0029] Two symmetrically mounted clips 5 and positioning rings 6 are respectively located on the outer walls of the two ends of the pipes 1, and the inner wall of the clip 5 is clamped with the outer wall of the pipe 1, and the inner wall of the positioning ring 6 is plugged with the outer wall of the clip 5;
[0030] The outer shell 2 is rotated to push the positioning ring 6, so that the positioning ring 6 can press the clamp 5 under the action of limiting the clamp 5 in the inner cavity of the straight-through body 3, so that the inner wall of the clamp 5 locks the outer wall of the pipe 1, and the pipe 1 is locked in the inner cavity of the straight-through body 3.
[0031] The material of the clip 5 is copper or aluminum;
[0032] The use of copper or aluminum materials can effectively prevent rust and increase service life.

If the high-pressure air plastic quick connector is loose, a wrench can be used to clamp the outer shell 2 and the straight-through body 3 respectively to lock the connection of the high-pressure air plastic quick connector, so as to better improve the sealing effect of the high-pressure air plastic quick connector.
