The invention relates to a worm and gear type lifting platform. The worm and gear type lifting platform comprises a pedestal and an end cover; the end cover is arranged above the pedestal; a round hole is formed in the upper head face of the pedestal; a vertically arranged rotating shaft is arranged in the round hole; a worm and a worm gear arranged horizontally and engaged to each other are arranged at the joint between the pedestal and end cover; the worm gear is arranged on the rotating shaft in an interference fit mode, and one end of the worm extends out of the pedestal; the end cover is provided with a workbench capable of moving up and down; the upper end of the rotating shaft is in threaded connection with the workbench. When working, through rotating a hand wheel, the worm drives the worm gear to rotate so as to drive the rotating shaft to rotate, and the rotating shaft enables the workbench to move up and down through threaded transmission. The worm rotates by a scale according to the worm and gear transmission ratio and threaded transmission pitch through manual regulation, the workbench ascends or descends a little to achieve precise regulation, and the cost is low.
