Problems solved by technology

[0002] At present, the hand-cranked mobile lifting devices used in daily life, especially those mainly used in hospitals or medical beds in the rehabilitation industry, simply say that the structure of the crank handle mostly uses linear direct transmission, and directly installs gears or gears on the main shaft. The universal joint directly drives the main shaft through the hand-operated device installed at one end of the main shaft to control the movement and elevation; such a device has large transmission resistance, which is time-consuming and labor-intensive; and the hand-operated device will occupy a large space when it is not in use; bring great inconvenience
