In this embodiment, the fixing flange of the first joint body, the second joint body and the fixing flange may be made of hard plastic or metal.

In this embodiment, as shown in fig. 2 and fig. 3, in order to realize accurate butt joint between the first connector body and the second connector body of the quick connector, 2 fixed convex grooves 12 are provided on the first connector body, 1 fixed convex groove 13 is provided on the first connector body, and the fixed convex grooves 12 and the fixed convex grooves 13 have different sizes and shapes. The number of the fixing grooves on the fixing flange is 3, the sizes of the fixing grooves 21 and the fixing grooves 22 are different, and the shapes of the fixing grooves 21 and the fixing grooves 22 can be the same or different, wherein the fixing grooves 21 are arranged corresponding to the fixing convex grooves 12, and the fixing grooves 22 are arranged corresponding to the fixing convex grooves 13. In this embodiment, the first joint body is provided with 4 fluid pipe interfaces 11, the second joint body is provided with 4 fluid pipe interfaces 31 corresponding to the fluid pipe interfaces in the first joint body, the diameter of the fluid pipe interface 11 disposed on the first joint body is smaller than that of the fluid pipe interface 31 disposed on the second joint body, and in order to ensure that the fluid pipe interface 11 disposed on the first joint body is in tight butt joint with the fluid pipe interface 31 disposed on the second joint body, a seal ring 6 is radially disposed in the fluid pipe interface disposed on the second joint body. In some embodiments, the sealing ring 6 can be sleeved on the fluid pipeline butt joint port 11 of the first joint body. The fluid pipeline butt joint arranged on the first joint body and/or the second joint body can be provided with an internal smooth mode and can also be provided with an internal thread mode. In this embodiment, the fluid line interface may be provided for multi-line transfer of a single fluid or for multi-line transfer of a plurality of fluids.

In some embodiments, the second connector body is provided with at least one hole, the hole is a blind hole 31, the elastic body, in this embodiment, a spring 5, is disposed in the blind hole 31, the pin 4 is disposed in the spring 5 to form a spring pin, the diameter of the pin is smaller than the inner diameter of the spring, and the pin is provided with a ferrule 41, which is clamped in the spring body.
