The plate 12 is longitudinally connected to the reducer 22, and the connecting frame 24 is installed on the rotating shaft 23; the fixing mechanism 03 includes a base 31, three groups of shock absorbers 32, three groups of springs 33, a fixing seat 34, two groups of splints 35 and two groups of locks 36. The base 31 is installed on the connecting frame 24, and the connecting frame 24 has a groove. The three groups of shock absorbers 32 are all installed in the groove of the connecting frame 24. The three groups of springs 33 are respectively mounted on the three groups of shock absorbers 32. The fixing seat 34 is slidably installed in the groove of the connecting frame 24 and connected to the top of the three groups of shock absorbers 32. The two groups of splints 35 are rotatably installed on the connecting frame 24.

The rotating shaft 23 then drives the connecting frame 24 and the cylinder back to their original position, making it easier for staff to replace the cylinder. The two sets of filters 14 filter impurities in the water. Two sets of baffles 15 prevent water from spilling outside the cavity of the water tank 11 during the cylinder's rotation.

Then the three groups of shock absorbers 32 drive the fixing seat 34 to slide downward to fix the gas cylinder. Then the staff rotates the two groups of clamps 35 and uses the two groups of lock buckles 36 to lock and connect the two groups of clamps 35. By covering the surfaces of the base 31, the fixing seat 34 and the two groups of lock buckles 36 with rubber pads, the hard friction between the gas cylinder and the fixed clamping device is reduced to prevent the surface of the gas cylinder from being scratched. At the same time, the rubber pad can increase the friction to prevent the gas cylinder from falling off the fixing mechanism 03.

Then the rotating shaft 23 drives the connecting frame 24 and the gas cylinder to reset, which is convenient for the staff to replace the gas cylinder. The two groups of filters 14 filter impurities in the water. By setting two groups of baffles 15, water is prevented from being spilled outside the cavity of the water tank 11 during the rotation of the gas cylinder.
