The racks 102 on both sides move The two arc-shaped clamping plates 103 are driven to move toward the middle while moving, and the slide groove 101 prevents the two racks 102 from deviating from the trajectory when moving. As the arc-shaped clamping plates 103 on both sides gradually move, the outer surface of the gas pressure gauge body 104 is slowly and firmly clamped between the two arc-shaped clamping plates 103, so as to prevent the gas pressure gauge body 104 from shaking left and right, thereby preventing the gas pressure gauge body 104 from shaking, avoiding inaccurate measurement of the gas pressure gauge due to shaking, and being able to firmly clamp the gas pressure gauge, thereby improving the test accuracy of the gas pressure gauge.
