Disclosed is a height-adjustable frame. The height-adjustable frame overcomes the defects that conventional frames are fixed in structure and not adjustable in height. Through matched connection among a foot plate, fixing lead screws, a top plate, fixing nuts, a rotary lead screw, a bearing and a bearing sleeve, a lifting structure is formed, wherein the inner face of the foot plate is parallel to the inner side face and the outer side face of the top plate and is opposite to the inner side face of the top plate. The height-adjustable frame has the advantages that the top plate can rise and fall freely, and thus, requirements on rise or fall of a driving main machine fixedly connected to the top plate are met; replacement of a driving belt is not needed during rise or fall of the driving main machine; the height-adjustable frame is simple in structure, reasonable in design and convenient to operate.
