How to use: Between uses, it is necessary to determine the state that the patient needs to use, that is, the state of use of the bed or the state of wheelchair use, and can be switched back and forth through the switching device. Take the example of switching from a hospital bed use state to a wheelchair use state. First, by rotating the operating handle 14 to 180°, the driving wheel 47 rotates synchronously, and the driving wheel 47 also rotates 180°, that is, half a circle. The driving wheel 47 thus drives the first transmission wheel 45 to rotate. Since the diameter of the driving wheel 47 is 0.5 times the diameter of the first transmission wheel 45, the rotation angle of the first transmission wheel 45 is 90°, and the adjustment of the operating handle 14 is completed. After that, the operating handle 14 can be fixed by a cover body (not shown in the figure) adapted to the first fixing groove 13 . Because the scroll wheel 41 is eccentrically arranged on the rotating disk. Therefore, the scroll wheel 41 will move from the position shown in FIG. 6 to the position shown in FIG. 7 , so that the scroll wheel 41 is in contact with the ground, thereby realizing the function of the wheelchair. At the same time, since the bed boards in the use state of the hospital bed are all located on the same plane, the medical staff can adjust the angles between the first bed board 1 , the second bed board 2 and the third bed board 3 according to actual needs to make To the most suitable use for the patient, after the adjustment is completed, tighten the bolts to prevent the wheelchair bed from collapsing under load. Through the above steps, the patient can switch to using the wheelchair, and the operation is very simple.

When the medical staff needs to switch to the use state of the hospital bed, the operation opposite to the above steps can be repeated.
