The invention discloses an automatic elevator convenient to move up and down. The automatic elevator convenient to move up and down comprises a body. Symmetrical fixed bars are symmetrically and fixedly arranged left and right on the top surface of the body, lifting racks are slidably connected to the two symmetrical fixed bars, and lifting blocks are arranged on the lifting racks. Compared with an existing ladder, people can be driven to lift automatically through the rotating lifting gears, so that the manpower and material resources are saved, and meanwhile, the lifting efficiency can be improved effectively. At the same time, the lifting shaft can be driven to rotate by transmission between a worm wheel and a worm. The safety of the elevator is improved by means of a self-locking characteristic between the worm and the lifting gear, and people are prevented from falling off. Meanwhile, feet of people can be fixed roughly, so that the safety can be improved to a certain extent.
