System for adjustable elevating platform and have it

The utility model discloses a system for adjustable elevating platform and have it. Adjustable elevating platform is including supporting the main part, two -way lead screw, first platform and second platform, and load -bearing platform, it sets up on supporting the main part to by first platform and second platform centre gripping, when two -way lead screw was rotatory, two -way lead screw converted the gyroscopic moment power of the two -way lead screw axial direction in the edge motion of first platform and second platform to, makes first platform and second platform keep away from the motion each other in opposite directions or each other, when first platform and the 2nd platform movement, first platform and second platform combined action make load -bearing platform can support main part - load -bearing platform orientation motion relatively. Adopt this kind of structure can make load -bearing platform support main part - load -bearing platform direction motion relatively to make the article that bear keep away from or be close and support the main part in support main part - load -bearing platform direction on the load -bearing platform, and can come precise adjustment through the motion of controlling first platform and second platform.
