Clamping and pressing thin-wall stainless steel pipe connecting structure with interval concave parts

The clamping and pressing thin-wall stainless steel pipe connecting structure comprises a first pipeline, a connecting pipe is arranged in the first pipeline, a second pipeline is arranged on the right side of the first pipeline, and connecting grooves are formed in the inner wall of the first pipeline and the inner wall of the second pipeline. According to the device, the first fixing ring is arranged, a connecting pipe can be extruded to deform through cooperation of the first fixing ring and a second fixing ring, and therefore the first pipeline and the second pipeline can be fixed, and the operation mode is convenient; the fixing effect of the connecting pipe on the first pipeline and the second pipeline can be further improved through cooperation of the connecting grooves, the use performance of the connecting pipe is improved, sealant can be injected into the pipelines through the sealant injection openings, and glue can make full contact with the pipelines through cooperation of the flow guide grooves
