[0028] Specifically, the first connector 1 adopts a first-specification connector 11 or a second-specification connector 12; one end of the first connector 1 is used to connect to the corresponding pipeline 10.

[0029] Specifically, the second connector 2 adopts the first specification connector 11 or the second specification connector 12; one end of the second connector 2 is used to connect to the corresponding pipeline 10.

One end of the second specification connector 12 is inserted into the pipeline 10 so that an additional locking component is needed at this end. Therefore, the connector buckle 3 can achieve the connection of the pipeline 10 by different combination methods, regardless of whether the first specification connector 11 or the second specification connector 12 is selected for the first connector 1 and the second connector 2.

[0033] In some embodiments, the connector buckle 3 adopts a first-specification buckle 31, a second-specification buckle 32, or a third-specification buckle 33.

[0044] In this embodiment, the external threaded tube 323a is set in a half-open manner, with one half set on the second specification body 321 and the other end set on the second specification end cap 322, so that the external threaded tube 323a is formed when the second specification body 321 and the second specification end cap 322 are put together, and then locked by the nut 323b.

[0045] like Figure 5 As shown, in some embodiments, the end face of the mating end 111 is provided with a first annular recess 111a and a second annular recess 111b; wherein the cross-section of the first annular recess 111a is rectangular; the cross-section of the second annular recess 111b is triangular; and the first annular recess 111a is located on the periphery of the second annular recess 111b.
