step two: when a patient needs to turn over, the threaded rod (1204) is rotated to change the position of the nut block (1203) arranged on the threaded rod (1204), namely the position of the connecting rod (804) can be changed, so that the angle between the connecting rod (804) and the sliding rail (11) is changed, and then the angles of the second fixing block (803) fixed on the connecting rod (804) and the turn-over plate (802) are changed, so that the turn-over plate (802) is turned upwards, and the patient is helped to turn over;

step three: when a patient needs to back, a crank (705) positioned on the back of the bed frame (1) is rotated, the distance between the threaded connecting rod (702) and the sleeve (701) is changed under the action of the threads, the angle of the second supporting frame (9) can be driven to change, then the angle of the back plate (10) fixed on the second supporting frame (9) is driven to change, and the back lifting function is realized when the back plate (10) is turned upwards;

step four: when a patient needs to leave the bed, the knob (16) is rotated to enable the knob (16) to abut against the hinge shaft of the guardrail (13), so that the guardrail (13) is fixed, and the guardrail (13) can be put down by reversing the knob (16) in the same way to bring convenience for the patient to get off the bed;

step five: when the second leg-bending plate (6) is positioned below the bed frame (1) and the back-lifting plate (10) is turned upwards, the patient can be in a sitting state.
