[0072] When the angles of the backrest plate 7 and the leg support plate 10 need to be adjusted, the first knob 301 is turned to drive the bidirectional screw rod 303 to rotate through the transmission rod 302. At the same time, the two movable push plates 305 drive the locking plug block 304 and the locking clamping plate 306 to move synchronously through the threads under the drive of the bidirectional screw rod 303. At this time, the locking plug block 304 is separated from the outer wall of the positioning rotating plate 203 by movement, so that the locking of the positioning rotating plate 203 can be released.

[0073] Then, the backrest plate 7 is pushed to rotate along the outer wall of a group of fixed shafts 12. In this process, the positioning plug block 205 is squeezed by the outer wall of the backrest plate 7, and the connecting push plate 201 is pushed to slide along the inner wall of the support frame 5 through the limiting push plate 206 and the fixed push rod 207.

[0075] When the user needs to transport a special passenger with limited mobility, rotating the first knob 301 can make the locking card plate 306 move along the inner wall of the limiting slot 309 until the locking card plate 306 contacts the inner wall of one end of the limiting slot 309, thereby releasing the locking of the positioning rotating plate 203 and releasing the docking fixation of the docking frame 307 and the base 6, and then push the backrest board 7 and the leg support board 10 to flip over respectively until the upper surfaces of the backrest board 7 and the leg support board 10 are in the same horizontal state with the upper surface of the seat cushion bottom plate 1, at this time, the reinforcing plate 8 is driven by the backrest board 7 to contact the outer wall of the support frame 5, so that the user can be in a lying state, and then the second knob 404 is rotated, at this time, the bolt 403 is driven by the second knob 404 to move along the inner wall of the reinforcing plate 8 through the thread until the bolt 403 and the backrest board 7 are separated from each other, thereby releasing the limit of the limiting slide bar 402;

[0076] The first support frame 401 is then pushed to drive the limiting slide bar 402 to slide along the inner wall of the backrest plate 7. At this time, the reinforcing rod 405 is inserted into the inside of the limiting slot under the push of the limiting slide bar 402, so that the seat cushion base plate 1 and the backrest plate 7 can be reinforced at the rotation position. Then, the second knob 404 can be turned to reset the bolt 403, so that the limiting slide bar 402 can be limited and fixed. Then, the seat cushion base plate 1, the backrest plate 7, and the leg support plate 10 can be lifted through the second support frame 11 and the first support frame 401. In this process, the locking card plate 306 slides along the inner wall of the limiting card slot 309 through the docking plug-in frame 307 under the drive of the support frame 5 until the docking plug-in frame 307, the docking plug-in plate 308 and the base 6 are separated from each other, so that the seat can be temporarily used as a stretcher to transport special passengers with limited mobility in a seamless manner.
