CN102440555A , wherein the height of the desktop is changeable by rotating a threaded rod, and the Chinese patent applicationCN102715729B , which discloses a lift table including a desktop, a switch, and two support assemblies comprising a base, a motor, a reducer, a screw rod, two supporting rods, and a torsion spring. Therein, the motor, reducer, and wire rod are installed inside the base, whereas the reducer and the wire rod are connected to each other. The motor is connected to the two supporting rods at the lower end, by means of the reducer and the wire rod, and the two supporting rods are connected to each other by means of the torsion spring. The desktop cover plate comprises a base plate, a top surface decorative board, and a lateral decorative plate. The switch is installed on the top surface decorative board, or on the lateral decorative plate. The upper end of the support rod is connected to a substrate, and the two supporting rods are arranged symmetrically along the centre of the substrate. Tables of the above types can be raised or lowered, but this function is achieved by means of a mechanical drive, which is prone to mechanical failure and making them unable to use. - The problem to be solved by the present invention is to provide a combined lift table with a simple structure and a low failure rate.
