Claim 8:
9. An elevating apparatus based on a hetero-oriented, non-isometric, dual-spiral drive structure, comprising
a first support and a second support that are telescoped together in a manner that they can rotate with respect to each other,
and comprising a first carrier and a second carrier that spirally encircle the first support, wherein
the first support is provided with a first recessed portion that serves to limit the second carrier to spirally move upward/downward and does not interfere with the first carrier,
and is further provided with a first raised portion that corresponds to a connection profile of the first carrier and is arranged opposite to the first recessed portion; and
the second support is provided with a second recessed portion that serves to provide the first carrier and/or the second carrier with a force along an axis of the first support, in which
a connector connected to the second carrier connects and/or leans against the first raised portion in a manner that the connector passes through the first recessed portion and the second recessed portion to be able to form, together with the second support and the first support, a simply-supported-beam force-bearing structure.
