When in use, the screw sleeve 19 can be guided when moving by the mutual cooperation between the guide groove 21 and the guide block 22, so that the screw sleeve 19 is more stable when moving. The nursing bed body 3 can be guided when moving by the cooperation of the guide rod 23, so that the nursing bed body 3 is more stable when moving.

[0023] Working principle: First, start the second servo motor 17 to drive the screw 18 to rotate. Under the limit of the guide groove 21 and the guide block 22, the screw 18 is used to drive the screw sleeve 19 to move, and then the hinge rod 20 is driven to move. Under the guidance of the guide rod 23, the hinge rod 20 is used to drive the nursing bed 3 to move, and the nursing bed 3 is adjusted to an appropriate height. Then the patient can rest on the nursing bed 3. When eating, the medical staff takes out the table board 5 and puts one end of the connecting rod 6 into the inside of the mounting seat 8, so that the connecting rod 6 and the mounting seat 8 are engaged with each other, and then Then, the first servo motor 10 is started to drive the threaded rod 11 to rotate, thereby driving the threaded sleeve 12 to move, and then under the limitation of the limit groove 14 and the limit block 15, the threaded sleeve 12 is used to drive the movable cavity 13 to move, and the movable cavity 13 is moved to the inside of the positioning hole 7, so as to limit the position of the connecting rod 6 and complete the convenient installation of the table board 5. When the table board 5 needs to be disassembled after use, the first servo motor 10 is started to reverse it, and the movable cavity 13 is moved out from the inside of the positioning hole 7. At this time, the connecting rod 6 can be taken out from the inside of the mounting seat 8 and the table board 5 can be removed.
