[0039] In some examples, in order to achieve the compression sealing and anti-loose effect, the compression sealing assembly 4 is designed, which comprises an outer threaded layer 4-1, an outer sleeve layer 3 screwed on the outer threaded layer 4-1, an outer ring groove 4-2 formed on the surface of the joint body 1, an inner ring groove 4-3 formed on the inner surface of the outer sleeve layer 3, a plurality of springs 4-4 arranged in the inner ring groove 4-3, and a compression block 4-5 connected with one end of the spring 4-4, the compression block 4-5 can press the gas hose 2 in the outer ring groove 4-2 by the elastic force of the spring 4-4, thereby achieving the effect of compression sealing.

[0040] As shown in Figures 1-5 , the present embodiment proposes a reinforcing support assembly 5, which comprises a pair of protrusions 5-1 arranged on the opposite ends of the outer surface of the outer sleeve layer 3, an insertion groove 5-2 formed on the surface of the protrusion 5-1, a fixing sleeve 5-3 inserted and connected in the insertion groove 5-2, a threaded stud 5-4 screwed in the fixing sleeve 5-3, and a support block 5-5 arranged at one end of the threaded stud 5-4.
