ABSTRACT:
Through combination of gears with different sizes in a transformation gear set configured in the height adjustment device, the height adjustment device can be fine-tuned. When an actuator of the height adjustment device is pressed, a first gear engaging with the actuator rotates and has a first relative distance with the actuator while a second gear engaging with a rack of the supporter has a second relative distance with the rack. The second relative distance is shorter than the first relative distance and the supporter is adjusted in a large scale and is fine-tuned through operating one single actuator.
