8. A nursing bed lifting device according to claim 1, wherein the method of using the nursing bed lifting device, the specific steps are:

Step 1: The patient is lying on the bed, and when the device needs to be used to assist the patient in lifting his back, the first hydraulic pump (14) under the upper body pad (2) is activated by the PLC controller (16), and the first hydraulic pump (14) is used ) drives the first hydraulic telescopic rod (12), the first hydraulic telescopic rod (12) cooperates with the expansion and contraction of the spring telescopic rod (13) to drive the support plate (11) to rise and fall, and the support plate (11) rises and falls When the upper body pad (2) is turned on, the rotating rod (20) at the end of the upper body pad (2) rotates, thereby driving the upper body pad (2) to turn over, so as to assist the patient in lifting the back;

Step 2: When it is necessary to assist the patient to turn sideways or to move the muscles and bones of the back, the PLC controller (16) controls the two air pumps (29) to start at the same time, and the air pump (29) is used to drive the extension and contraction of the pneumatic telescopic rod (30) to drive the first air pump (29). A back pad (27) and a second back pad (28) are turned around the short axis (34) to increase the range of assisting the patient to lift their backs when the device is in use; when one of the air pumps (29) is controlled by the PLC controller (16) ) when starting, use the air pump (29) to drive one of the back pads to turn over to assist the patient to turn sideways; when the PLC controller (16) controls the two air pumps (29) to switch back and forth to start, use the first back pad (27), The second back pad (28) is turned back and forth to assist the patient to move the back muscles and bones;

Step 3: When the patient needs to get up and the waist cannot exert force due to the trauma, the PLC controller (16) controls the second hydraulic pump (18) and the drive motor (35) to start simultaneously, and the second hydraulic pump (18) ) to drive the second hydraulic telescopic rod (19) to extend and retract and push the support base (22), so that the lumbar pad (3) and the leg pad (4) are folded, and the patient’s legs are driven to bend, and the drive motor (35) drives the The shaft (10) is rotated to flip the flip (24), which provides a force application point for the patient's foot when flipped, and assists the patient to stand up.
