[0033] First, the medical staff puts a mattress on the two support plates 7, and the patient lies flat between the two support plates 7. When the bedridden patient needs to be turned over, the medical staff first deflects the patient's head in the turning direction, and then drives the second transmission shaft 20 to slide on the first transmission shaft 18 through the push rod 23 and the driving disc 22 according to the turning direction of the patient, and selects the first gear 25 to mesh with the two fourth gears 29 or the third gear 32 to mesh with the two fourth gears 29 according to the turning direction of the patient;

[0034] After the selection is completed, the medical staff starts the motor 24, and the power output shaft of the motor 24 rotates through the card plate 19 to drive the second transmission shaft 20 to rotate. The rotation of the second transmission shaft 20 drives the first gear 25 and the third gear 32 to rotate synchronously. According to the patient's turning direction, one of the first gear 25 and the third gear 32 drives the two fourth gears 29 at the same end to rotate. The fourth gear 29 rotates to drive the third transmission shaft 28 and the second pulley 30 concentric therewith to rotate. The second pulley 30 rotates to drive the first pulley 13 to rotate through the transmission belt. The rotation of the first pulley 13 drives The first screw shaft 12 coaxial therewith rotates, and the first screw shaft 12 rotates to drive the first drive plate 15 screwed with the first screw shaft 12 to slide in contact with the base plate 1, that is, the first drive plate 15 which is initially far away from the middle support plate 4 moves toward the middle support plate 4, and then the fourth ear seat group 16 on the top of the first drive plate 15 applies force to the support plate 7 through the third ear seat group 11 with the assistance of the connecting rod 17, so that the support plate 7 rotates around the axis of the first connecting shaft 10, thereby assisting the patient with half of his body lying on the support plate 7 to complete the turning operation under the synchronous coordination of the medical staff;

[0035] The lateral distance between the stop plate 14 and the middle support plate 4 is greater than the lateral distance between the third ear seat group 11 and the middle support plate 4, thereby preventing the support plate 7 from rotating too much and causing the patient to fall.
