The test mechanism of claim 7, wherein: when the fourth step of the packaging process is carried out, the ROSA is taken out of the sealing device, then the ROSA is placed into the sealing box, meanwhile, the sliding block is pushed to the other end of the sliding rail until the vent hole, the through hole and the gas channel on the sealing box form an integral vent channel, the sealing box is subjected to air suction through the gas pipe joint, the content of helium in the extracted gas is detected, the whole air suction and detection process lasts for about 1 minute, wherein a large amount of helium components can be detected by an instrument in the first few seconds, the helium components are helium contained on the surface of a product, and the instrument does not judge a measured value in the stage; the helium detection level then rapidly drops to a very low level; if the product leaks, helium leakage is continuously detected by the instrument under the condition of external negative pressure, so that the test value is obviously higher than a normal level.

9. The test mechanism of claim 7 or 8, wherein: the cushion compression stress p, the cushion compression area S, and the reaction force when the cushion is compressed

The thrust of the cylinder is greater than the reaction force R.
