step S1, when the patient lies on the first turnover bed board, when the medical staff needs to turn over the patient, the medical staff pulls the lifting handle of the second fixing piece to pull the locking bolt out of the locking groove of the second extending plate to lift the second extending plate upwards, so that the second turnover bed board is folded upwards to cover the first turnover bed board;

step S2, when the second turnover bed board is folded and covered on the first turnover bed board, the first half gear and the second half gear are matched to form a gear, the first semicircular rod and the second semicircular rod are matched to form a rotating rod, the second extending plate corresponds to the first extending plate, and the first turnover bed board and the second turnover bed board can be fixed by screwing the fixing nut through the first threaded hole and the second threaded hole;

step S3, starting a driving motor, wherein the driving motor rotates positively to drive a driving gear to rotate, and the driving gear is meshed with a gear formed by matching a first half gear and a second half gear, so that the driving gear can drive the gear to rotate, and the gear can drive a rotating rod formed by matching a first semicircular rod and a second semicircular rod to rotate;

step S4, when the first semicircular rod and the second semicircular rod rotate to drive the first turnover bed board and the second turnover bed board to rotate 90 degrees clockwise, the worker loosens the first fixing piece to disassemble the detachable movable plate, and after the first turnover bed board and the second turnover bed board turn 90 degrees clockwise again, the first turnover bed board and the second turnover bed board continue to turn to the initial position of the detachable movable plate, so that the patient can turn over;

step S5, the medical staff pulls the lifting handle of the second fixing piece to pull out the locking bolt, the detachable movable plate is detached to the original position of the second turnover bed plate, the medical staff loosens the lifting handle, the locking bolt returns to the locking groove of the third extending plate through the resetting function of the resetting spring, and the detachable movable plate is fixed at the initial position of the second turnover bed plate;

step S6, after the patient turns over, the medical staff spirally disassembles the fixing nut, folds the first turning bed board upwards to unfold the first turning bed board, and the patient lies prone on the second turning bed board;

step S7, medical personnel pull the lifting handle of the first fixing piece to pull out the locking bolt, the medical personnel loosen the lifting handle, the locking bolt returns to the locking groove of the second extension plate through the reset function of the reset spring, and the second turnover bed plate is fixed. Through the use steps from the step S1 to the step S7, the medical staff can better realize the turning over of the patient.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
