A lifting structure operating precisely and stably at all stages of a lifting and lowering action includes a lifting assembly and a driving assembly. The lifting assembly includes two first links, two second links, and two seats. A first connecting arm of each first link has first and second ends, the first end having a first gear structure. A second connecting arm of each second link has third and fourth ends, a second and complementary gear structure being provided on the third end. The first gear structures are engaged and the second gear structures are engaged. The second end is rotatably connected to the fourth end through one of the two seats. The driving assembly can drive the two seats towards each other to perform lifting or drive them away from each other to perform lowering.
