The invention discloses a screw elevator. The screw elevator comprises a fixing base, a screw and a lifting platform. The lifting platform is arranged above the fixing base in parallel. The top of the screw is perpendicular to the bottom of the lifting platform. The screw is perpendicular to the fixing base and extends to the position below the fixing base. Sliding blocks are arranged at the four corners of the lifting platform respectively. Four stand columns are arranged on the fixing base. Each stand column is axially provided with a sliding groove corresponding to the corresponding sliding block. In this way, according to the screw elevator, the sliding blocks at the corners of the lifting platform are supported by the four stand columns respectively in the lifting process of the lifting platform, so that shaking of the sliding blocks is restrained, the sliding blocks are only allowed to move up and down in the vertical direction, and the lifting platform is prevented from inclining; besides, the lifting platform is buffered by hydraulic supporting rods when descending to the bottom, so that the stability of the lifting platform is improved.
