The elastic soft sleeve is a rubber sleeve.
The end face of the elastic soft sleeve exceeds the end face of the straight pipe connector.
Annular grooves are arranged on the periphery of the long joint rod at intervals.
The length of the joint long rod is 120mm-150 mm.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model is convenient for connecting the oxygen belt and the oxygen pipe, can adjust the oxygen at any time, ensures that the joint is oxygen-tight, and improves the safety factor.
