[0036] When the tester is in use, the bevel frame 25 and the rounded plate 26 can protect precision components such as the flow meter 10 and the pressure gauge 701, prevent the external environment from affecting the test results, and prevent the components from being easily damaged by bumps. When components such as the pressure regulating valve 7, the flow regulating valve 1001 and the conversion valve 9 need to be adjusted, or when a component fails and needs maintenance, just pull out the rod 27 to the right, then rotate the rounded plate 26 forward, and adjust or repair components such as the pressure regulating valve 7 and the flow regulating valve 1001. After the adjustment or maintenance is completed, rotate the rounded plate 26 in the opposite direction to restore the rounded plate 26 to its original position, and finally insert the rod 27 back to its original position to fix the rounded plate 26.
