Elevating apparatus based on hetero-oriented, non-isometric, dual-spiral drive structure

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.

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.
