Oxygen and acetylene cylinder supporting frame

The utility model discloses an oxygen and acetylene cylinder supporting frame which comprises two fixing supporting legs, the upper ends of the two fixing supporting legs are jointly connected with a fixing sector ring, containing grooves are formed in the bottoms of the two fixing supporting legs, and two longitudinal sliding grooves and a plurality of limiting holes are symmetrically formed in the lower portions of the two fixing supporting legs. Each limiting hole and the corresponding longitudinal sliding groove communicate with the corresponding containing groove in position, and a supporting mechanism is arranged between the two fixing supporting feet. The gas cylinder fixing device has the advantages that after a gas cylinder is inserted into the fixing sector ring, the fixing supporting legs and the gas cylinder jointly form a triangular stable structure, the gas cylinder can be conveniently and rapidly fixed, safety accidents caused by gas cylinder toppling in the operation process are avoided, the d
