[0065] A pneumatic clamping mechanism 200, which is used to seal one end of the conveying device, and is fixedly connected to the first connecting pipe 4;

[0066] A support assembly 100, wherein the support assembly 100 is used to adjust the height of the pneumatic clamping mechanism 200;

[0067] The bottom support mechanism 400 is used to support the conveying device and adjust its height.

[0068] In the embodiment of the utility model, when in use, the gas delivery equipment is placed on the bottom support mechanism 400, and one end of the gas delivery equipment is adjusted to be flush with the first sealing plate 7 through the bottom support mechanism 400, and then the pneumatic clamping mechanism 200 is adjusted to be flush with the other end of the gas delivery equipment through the support assembly 100, and then the other end of the gas delivery equipment is squeezed and sealed by the pneumatic clamping mechanism 200, so as to seal the output end and the input end of the gas delivery equipment, and then the first connecting pipe 4 is supplied with gas through the inflator 3, and the gas enters the gas delivery equipment and the second connecting pipe 5 through the pneumatic clamping mechanism 200 until the air pressure value of the barometer 6 is the same as the air pressure value of the inflator 3. At this time, by observing the values ​​displayed by the two, it is easy to judge whether the gas delivery equipment is leaking. The operation is simple and convenient, and it can adapt to gas delivery equipment of different specifications and types.
