[0037] The working principle of this embodiment is as follows:

[0038] When it is necessary to move the patient from the transfer vehicle to the operating bed, first move one side of the transfer vehicle closer to the side of the operating bed, start the first hydraulic cylinder 7, the hydraulic rod of the first hydraulic cylinder 7 extends out and drives the two scissor-type lifting frames 6 to rise through the first connecting rod 16, so that the seat board 2 rises. When the seat board 2 is flush with the operating bed, stop the first hydraulic cylinder 7, and then start the two second hydraulic cylinders 8. The hydraulic rod of the second hydraulic cylinder 8 extends out to drive the armrest 12 to move to the side of the seat board 2 and be flush with the seat board 2, and drive the back board 1 to rotate toward the horizontal plane where the seat board 2 is located through the armrest 12. At the same time, the armrest 12 drives the footrest bracket 3 to rotate toward the horizontal plane where the seat board 2 is located through the second connecting rod 17 and the third connecting rod 18, until the back board 1, the footrest bracket 3, the two armrests and the seat board 2 are in the same plane, stop the second hydraulic cylinder 8, at this time the patient is in a lying state, and the medical staff then moves the patient horizontally to the operating bed, and the patient's transfer from the transfer vehicle to the operating bed is completed.

[0039] When the operation is completed, the medical staff will move the patient from the operating bed to the transfer vehicle in a supine position, and then start the first hydraulic cylinder 7. The hydraulic rod of the first hydraulic cylinder 7 will retract and drive the two scissor lifts 6 to rise through the first connecting rod 16, so that the seat plate 2 drops to the original height, and then stop the first hydraulic cylinder 7. At this time, the two second hydraulic cylinders 8 will be started. The hydraulic rod of the second hydraulic cylinder 8 will retract and drive the armrest 12 to move to the original position, and drive the back plate 1 to rotate to the original angle through the armrest 12. At the same time, the armrest 12 drives the footrest bracket 3 to rotate to the original angle through the second connecting rod 17 and the third connecting rod 18. At this time, the support plate 11 in the support plate slot 21 is pulled out, and when the convex point 22 of the sliding telescopic rod 10 is pulled to the corner of the L-shaped slide groove 20, the sliding telescopic rod 10 is rotated. After the retracted rod 10 is in a vertical state, it moves downward along the vertical part of the L-shaped slide groove 20 and reaches the bottom surface of the slide groove. At this time, the bottom of the sliding telescopic rod 10 is tightly against the bottom surface of the slide groove, and the sliding telescopic rod 10 is fixed under the common limit of the bottom surface of the slide groove and the vertical part of the L-shaped slide groove 20. At this time, after the telescopic sliding telescopic rod 10 is adjusted to a suitable height, the support plate 11 is rotated to a horizontal level. At this time, the patient can lower his head and place his forehead on the support plate 11. The support plate 11 can help the patient better meet the requirements of lowering his head after surgery, and the patient does not need to control the angle and direction by himself, making the patient more comfortable. The patient who needs to tilt his head back does not need to pull out the support plate 11, but only needs to lean his head against the head pad 14, and the back plate 1 can be adjusted to a comfortable angle for the patient through the angle adjustment mechanism.
