Because the nursing bed is in the lowest position when the first lifting frame 21 and the second lifting frame 22 are in the recovery limit position, the nursing bed is in the highest position when the first lifting frame 21 and the second lifting frame 22 are in the supporting limit position, and the height difference between the bed frame 10 and the ground is between 120mm and 200mm when the nursing bed is in the lowest position, the nursing bed has the function of an ultralow bed, and patients can be prevented from falling. When the nursing bed is positioned at the highest position, the height difference between the bed frame 10 and the ground is between 800mm and 850mm, so that nursing staff can care patients without bending down.

The first lifter 21 and the second lifter 22 may have the same structure or may have different structures. When the two structures are different, the first lifting driving piece 211 can be used to drive the second lifting frame 22 to lift in the process that the first lifting driving piece 211 in the first lifting frame 21 drives the first lifting rod assembly 213 to lift. Of course, when the two structures are identical, the second lifting frame 22 has a second lifting driving member, and the second lifting driving member and the first lifting driving member 211 are disposed at intervals along the length direction of the bed frame 10.
