The invention discloses a gear lifting mechanism. The gear lifting mechanism comprises a rack, two guide rails, a lifting platform, two nuts, two screw rods and a drive mechanism. The guide rails are erected on the left side and the right side of the rack respectively. The left side and the right side of the lifting platform are each provided with a slide rod. The slide rods are each sleeved with the guide rail on the corresponding same side in the mode that the slide rods are capable of sliding up and down. The two slide rods are each fixedly provided with one of the nuts. The two screw rods are erected on the rack in a rotary mode, and the two screw rods are each connected with one of the nuts in a meshing mode. The drive mechanism is used for driving the two screw rods to rotate. The gear lifting mechanism is simple in structure; the lifting platform is driven by screw rod-nut pairs to lift. The gear lifting mechanism has a self-locking property, and is steady in driving, so that the work process of the lifting platform is safe and reliable.
