Claim 16:
17. An elevating apparatus based on a hetero-oriented, non-isometric, dual-spiral drive structure, being characteristic in 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 share the same spiral direction and spiral pitch,
the second support is provided with a second recessed portion that has a spiral direction different from that of the first recessed portion and has opposite openings in the second recessed portion's radial section, wherein
a first carrier is such configured that it spirally encircles the first support along the first raised portion; and
a connector connected to the second carrier acquires, in a manner that it passes through the first recessed portion and the second recessed portion to connect to and/or lean against the first raised portion, a driving force that is provided by rotation of the second support and drives the second carrier to move along the first recessed portion.
