[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Example:

[0027] like Figure 1-Figure 3 As shown, the present invention provides a technical solution for a copper pipe quick connector:

[0028] As shown in the figure, a copper pipe quick connector includes a connector sleeve 1, which includes an inner pipe sleeve 11 arranged inside the connector and forming an integrated structure, a groove ring 12 formed between the inner pipe sleeve 11 and the connector sleeve 1, a through hole 13 opened on the surface of the connector sleeve 1, a clamping hole 14 arranged on the outer surface of the connector sleeve 1 and forming an integrated structure with the through hole 13, a movable rod 15 with one end passing through the through hole 13 and extending into the groove ring 12, a rotating plate 16 arranged at the other end of the movable rod 15, a spring 17 wound around the outer surface of the movable rod 15 and located inside the through hole 13, and a clamping block 18 arranged at the end of the movable rod 15.
