1. An elevating apparatus based on a hetero-oriented non-isometric, dual-spiral drive structure, comprising
a first carrier and a second carrier, being characteristic in further comprising a first support and a second support that are telescoped together in a manner that the first support and the second support 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, wherein
the first carrier is connected to the first support along the first raised portion in a manner that the first carrier spirally encircles the first support; and
the second carrier acquires a driving force that is provided by rotation of the second support and drives the second carrier to move along the first recessed portion,
in a manner that a connector passes through the first recessed portion and the second recessed portion to connect to and/or lean against the first raised portion.
