[0009] It also includes two giving way components, which have the same structure and are respectively located in the two butt joints. The stopper can be pushed by the giving way components to perform blocking.

[0010] In one possible design, the yielding assembly includes a support rod fixedly connected in the docking joint, the outer wall of the support rod is sleeved with a torsion spring, one side of the stop block is fixedly connected with a connecting column, two sliding grooves are provided in the docking joint, and the two ends of the connecting column are correspondingly slidably connected in the two sliding grooves, two movable grooves are provided in the connecting column, and the two ends of the torsion spring slide in the two movable grooves respectively.

[0011] In a possible design, a conflict ring is provided on one side of the two moving heads that are close to each other, and the two conflict rings are respectively conflict-matched with the two limit rings.

[0012] In a possible design, the two moving heads are fixedly connected to a support frame on one side away from each other, and the two support frames are fixedly connected to a contact head on one side away from each other, and the two contact heads can respectively contact the two stoppers.

[0013] In a possible design, the outer walls of the two docking joints are provided with matching blocks, which can be easily driven to rotate by a wrench. At the same time, the outer shape of the moving head is in the shape of a nut, which is also convenient for rotating the moving head by a wrench.

[0014] In a possible design, the two mating blocks are fixedly connected to one side away from each other with a butt joint pipe, through which the butt joint pipe can be used to butt joint with the end of the pipeline respectively.

[0015] In the present application, when the quick connector is needed to connect two pipes, firstly, the two butt joints are respectively butted and fixed with the two pipes, and then, the butt joint is driven by the mating block to threadably connect the hollow screw rod with the nut in the moving head. The stopper in the butt joint is supported by the torsion spring and the moving head is supported by the inner wall at one end of the butt joint. As the butt joint rotates, the moving head slides along the outer wall of the limit ring until it fits tightly with the butt joint.
