At this time, the gas in the plurality of hollow cylinders 206 is sucked out, and under the action of the suction, the plurality of push plates 205 can slide at the inner walls of the plurality of hollow cylinders 206, at this time the plurality of transmission rods 204 pull the plurality of fixed plates 203 under the guidance of the plurality of push plates 205, so that the plurality of fixed plates 203 slide out of the inner walls of the plurality of connecting plates 210. At this time, under the action of gravity, the body 1 falls downward, and the separation between the body 1 and the cabin 2 is completed, so that the body 1 and the cabin 2 can be separated when the passenger plane is used, and the separation mode is relatively simple.

[0057] When the fuselage 1 and the cabin 2 are separated, the nitrogen gas sucked by the plurality of delivery pumps 212 is discharged through the output end into the interior of the second cross rod 309, and further inflates the air bag 301 through the flow guide pipe 308 and the inflation port 307. In normal use, the plurality of baffles 304 can slide on the outer surface of the plurality of cross shafts 303 respectively, and the plurality of convex plates 302 support the plurality of cross shafts 303. By rotating the plurality of baffles 304, the plurality of mounting plates 305 and one side of the inner wall of the storage groove 3 are in contact. The plurality of mounting plates 305 are fixed in the interior of the storage groove 3 by the suction force of the plurality of magnets 306. The plurality of baffles 304 support the air bag 301. When the air bag 301 is not inflated, the volume is small, and the plurality of baffles 304 can support the air bag 301. When inflated, the air bag 301 expands and the volume becomes larger, which can knock open the plurality of mounting plates 305, and further make the air bag 301 inside the cabin 2 support the cabin 2. If the cabin 2 falls on land, the air bag 301 can play a buffering role. If the cabin 2 falls into the sea, the air bag 301 can play a floating role, so that the cabin 2 will not sink, and the passengers can quietly wait for rescue, thereby increasing the survival chance of the passengers when the cabin 2 is separated, especially when landing on the water surface, the floating state of the cabin can be maintained to avoid sinking of the cabin.

[0058] After the fuselage 1 and the cabin 2 are separated, by opening the external power switch of the bidirectional motor 413, the output shaft of the bidirectional motor 413 can rotate forward and reverse, and further the output shaft of the bidirectional motor 413 drives the rotating rod 414 to rotate. Because the outer surface of the two bidirectional threaded rods 403 has two different helical thread grooves, the two sleeves 404 are connected with the two different helical thread grooves on the outer surface of the bidirectional threaded rods 403, and the two sliding cylinders 406 can slide on the outer surface of the round rod 405. When the bidirectional threaded rods 403 rotate in different directions, the two sleeves 404 move in opposite directions on the outer surface of the bidirectional threaded rods 403. At this time, the output shaft of the bidirectional motor 413 is controlled to rotate counterclockwise, and further the rotating rod 414 drives the second gear 416 to rotate, and further the second gear 416 drives the bidirectional threaded rods 403 to rotate counterclockwise, so that the two sleeves 404 drive the two transmission plates 407 to move in opposite directions, so that the plurality of positioning rods 408 slide out of the interior of the plurality of second through holes 417 and the plurality of first through holes 412, and the plurality of bottom plates 410 are not clamped by the plurality of positioning rods 408, and further the arc-shaped plates 411 are loose. When the cabin 2 falls downward, the arc-shaped plates 411 and the cabin 2 are separated, and the two mounting frames 4 inside the parachute 401 are opened, the air resistance of the cabin 2 is changed, and the falling speed is slowed down, so that the falling speed of the cabin 2 can be slowed down when the cabin 2 lands, the impact force when landing is reduced, and the safety of the cabin 2 in the landing process is improved.
