[0025] The working principle of the rotatable hanging basket in the above technical solution is explained as follows:

[0026] When the present invention is implemented in the rescue work, the hanging port 1 and the gravity rope are first installed, and then slowly lowered. The hanging basket body 4 is connected to the support seat 2 through the lifting rope 3. When it is placed at the rescue position, the rescuer on the hanging basket body 4 presses the connecting ring 41c downward on the upper surrounding layer 41. At this time, the telescopic slide 1b2 slides down along the positioning slide sleeve 1b3. During the sliding process, the lower connecting seat 1b4 pushes out the airbag ring 441 inside the lower surrounding layer 44. In this way, during the sea rescue, the hanging basket body 4 can float well on the sea surface, and as the upper surrounding layer 41 is compressed, the overall height of the hanging basket body 4 is reduced. The lowering of the upper layer 41 is achieved by lowering the connecting ring 41c and lowering the upper layer 41. ...

[0027] The upper surrounding layer 41 with telescopic function can not only improve the rescue efficiency and safety of rescue use, but also play a certain benefit when the hanging basket main body 4 is placed and stored. When the hanging basket main body 4 is not in use, the upper surrounding layer 41 can be retracted again, and as the upper surrounding layer 41 shrinks, the airbag ring 441 at the bottom of the lower surrounding layer 44 is brought out, which can avoid direct contact between the lower surrounding layer 44 and the ground, and the protective texture at the bottom of the extended airbag ring 441 can increase its contact roughness, so that when idle, the hanging basket will not shake left and right as the aircraft flies.
