Abstract

The utility model relates to a lifting desk, which comprises a desktop and hollow leg stands. The lifting desk comprises upper supporting tubes, crossbeams, threaded rods and sleeves, wherein the upper supporting tubes are movably connected with the leg stands through adjusters and can slide up and down. A motor or a handle drives bevel wheels in the upper supporting tubes to rotate and drives the threaded rods to move along the sleeve, so that the supporting tubes can move up and down along outer sleeves to adjust the height of the desktop; the upper supporting tubes at two sides is driven by a driving shaft in the middle to make synchronous movement, thus the lifting desk has the advantages of convenient adjustment and simple use.
