Abstract
A lifting bracket comprises an upper supporting board, a lower supporting board, a left supporting frame and a right supporting frame, wherein the left supporting frame and the right supporting frame are both formed by foldable supporting frames. Each foldable supporting frame comprises two parallel four-connection-rod mechanisms which are vertically adjacent. The vertically-adjacent four-connection-rod mechanisms achieve synchronous driving through two hinged driving arms. The upper supporting board and the lower supporting board are respectively connected onto middle connection boards and lower connection rods in the parallel four-connection-rod structures. When the lower supporting board is pulled downwards, the four-connection-rod mechanisms are folded upwards, the upper supporting board and the lower supporting board rise, the distance between the upper supporting board and the lower supporting board is shortened, and the upper supporting board, the lower supporting board, the left supporting frame and the right supporting frame do not occupy space.
