[0070] When the elastic support component 33 is working, the inflation work is realized through the inflation self-locking component 332. The specific operation is to plug the manual inflation airbag into the manual inflation airbag plug interface 3323, and the air enters the airbag cushion 331 through the air source tube 3322 and the U-shaped tube 3321. The controller 325 receives the air pressure data measured by the air pressure sensor 3324, and closes the micro electric control valve 3325 when the air pressure data reaches the set value to complete the inflation process. When deflation, the micro electric control valve 3325 can be opened by the controller 325 for deflation or the exhaust valve 3326 can be manually opened for deflation.

[0071] When the temporary support device 20 is working, the single-sided open-end zipper 221 is pulled and closed to complete the connection between the two folding airbags 211 and the two base airbags 212, and the base airbag 212 is inflated through the second inflatable self-locking component 25 until the air pressure in the base airbag 212 reaches the set value, and then the folding airbag 211 is inflated through the first inflatable self-locking component 24 until the air pressure in the folding airbag 211 reaches the set value. The working principles of the second inflatable self-locking component 25 and the first inflatable self-locking component 24 are consistent with the inflatable self-locking component 332. After completion, the user moves the shaft rod 233 through the operating rod 234, and the shaft rod 233 is engaged with the engaging groove 231 to complete the support point switching.
