[0048] like Figures 1 to 9 As shown, the handle 42 drives the sliding push plate 41 to move, so that the sliding push plate 41 pushes the first movable frame 44 and the second movable frame 45 to move and unfold by rotating the push rod 43, so that the locking block 46 is engaged with the fixed groove 9, and at the same time, the extrusion inclined surface 47 squeezes the pressing protrusion 53 and the pressing support plate 51 to move downward, so that the pressing support plate 51 and the pressing rod 52 squeeze the main airbag 61 to contract, and the expansion airbag 62 expands to push the elastic sealing strip 63 to move and unfold and engage with the sealing groove 10, and at the same time, the elastic sealing strip 63 squeezes and pushes the inspection door body 1 downward.
