Abstract
A height-adjustable support device comprises a support frame, a moving member, an elastic device, an underdriving gear set, a first cord-shape object, and a second cord-shape object. The moving member is arranged in a manner of moving along the support frame, so that the object is fixed and can be moved along the support frame. The elastic device is arranged at one end of the support frame in a manner of flexing in a direction parallel with a moving direction of the moving member. The underdriving gear set is fixed on the support frame, and includes a driving unit, a first rolling unit, a driven unit and a second rolling unit. When the moving member generates a first displacement, the first cord-shape object drives the driving unit to rotate together with the driven unit, further drives the second rolling unit to rotatablely rolls the second cord-shape object, so that the elastic device generates a second displacement smaller than the first displacement.
