[0027] The spacing adjustment mechanism 191 is installed on multiple binding straps 180. The setting of the spacing adjustment mechanism 191 is used to adjust the distance between the corresponding binding straps 180. The spacing adjustment mechanism 191 includes a first wing plate 1911, an arc plate 1912, a second wing plate 1914, a support plate 1915, a pin rod 1916, and a spring 1917. Different connecting shafts 190 are respectively installed on multiple first wing plates 1911 and multiple second wing plates 1914. One end of the arc plate 1912 is fixed on the outer wall of the first wing plate 1911, and the arc plate 1912 is slidably inserted into the second wing plate 1914. A slot 1913 is formed on the arc plate 1912, and a counterbore is formed on the second wing plate 1914.

[0029] Specifically, the working principle of this oxygen and water storage device with strong applicability: During use, the first support frame 150, the binding strap 180, the first wing plate 1911, and the second wing plate 1914 are sleeved on the high-pressure gas cylinder 110. Then, the pin rod 1916 is pulled to make the end of the pin rod 1916 leave the slot 1913. The first wing plate 1911 is pushed by the handheld part 194 to adjust the distance between the first wing plate 1911 and the second wing plate 1914, that is, to make the binding strap 180 clamp tightly on the high-pressure gas cylinder 110. After adjustment, the pin rod 1916 is released. Under the reaction of the spring 1917, the lower end of the pin rod 1916 is inserted into the slot 1913 to fix the arc-shaped plate 1912 in the second wing plate 1914. Then, the high-pressure gas cylinder 110 is placed on the bottom water tank 130. Then, the end water tank 120 is clamped on the high-pressure gas cylinder 110, and the end water tank 120 is fixed on the high-pressure gas cylinder 110 by bolts. Then, the end water tank 120, the bottom water tank 130, and the connection box 140 are installed together. This oxygen and water storage device with strong applicability facilitates the adjustment of the distance between the first wing plate 1911 and the second wing plate 1914 according to the models of the high-pressure gas cylinder 110, the end water tank 120, the bottom water tank 130, and the connection box 140, making the applicability of the binding strap 180 stronger and bringing a better use experience to the user.
