Three groups of cable ties 9 are fixed at the bottom position of the mounting platform 6, and the middle outer side of the connecting hose 8 is suspended on the outer side of the cable ties 9. By placing the air port 11 and the elastic airbag 10 on the outside of the aviation mechanical part body 13, the elastic airbag 10 can be placed in the circulation part of the aviation mechanical part body 13. At this time, the control component 3 is used to control the air pump 7 to perform air outlet processing, which can cause the elastic airbag 10 to expand. At this time, the elastic airbag 10 will fit in the circulation part of the aviation mechanical part body 13. When the valve 12 is fully closed, the connecting hose 8 will no longer supply air to the inside of the elastic airbag 10. At this time, air will only be supplied to the inside of the air port 11, and the pressure detection processing will be displayed by the pressure display table 2.
