[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3, an embodiment of the present utility model provides a high-pressure-resistant stainless steel quick connector structure, including: a stainless steel connector A1 and a stainless steel connector B2. A nut 3 is sleeved on the surface of the stainless steel connector A1, and the nut 3 is screwed onto the stainless steel connector B2. Support ears are symmetrically arranged on the surface of the nut 3, and a fixing component 4 for stable connection is installed on the support ears.
