A linear lifting device including a lifting column, a synchronous adjusting mechanism, a first motion element and a second motion element is provided. The lifting column has a fixed end and a movable end. The synchronous adjusting mechanism, disposed on the movable end, has a first force-bearing end and a second force-bearing end, which are respectively separated from the center of the synchronous adjusting mechanism by a rotating radius and remain at a synchronous state. The first and second elements respectively connect the first and second force-bearing ends for generating a first force to push the first force-bearing end to move in a first force direction and generating a second force to push the second force-bearing end to move in a second force direction, such that the movable end can move with respect to the fixed end in a resultant force direction of the first and second force directions.
