The present invention relates an elevating apparatus based on a hetero-oriented non-isometric, dual-spiral drive structure, comprising a first carrier and a second carrier, further comprising a first support and a second support that are telescoped together in a manner that they can rotate with respect to each other, the first support is provided with a first recessed portion and a first raised portion that shares the same spiral direction and spiral pitch, the second support is provided with a homo-oriented, isometric, dual-spiral second recessed portion that has a spiral direction different from that of the first recessed portion. The carrier of the present invention is provided in a simply-supported-beam, and the carrier force can be achieved without additional weight, and the operation is stable and reliable.
