The invention relates to the technical field of lifting devices, in particular to a lifting device with a stable lifting effect. The lifting device comprises a base, a lifting column, a lifting nut, alead screw, a shell body, an electric motor, a driving wheel, a driven wheel, an upper limiting switch, a lower limiting switch, a control mainboard and a control switch, wherein the lead screw is rotationally mounted on the base, the lifting nut is in threaded connection with the lead screw, the lifting nut is fixedly connected with the lifting column, the lifting column is connected with the shell body in a clamped mode, the limiting switches are mounted in the shell body, the lifting column is provided with triggering parts corresponding to the limiting switches, the electric motor is fixedly mounted on the base, the electric motor is fixedly connected with the driving wheel, the driven wheel is fixedly connected with the lead screw, the driving wheel meshes with the driven wheel, thecontrol mainboard is mounted in the shell body, the control switch is mounted on the shell body, and the control switch and the electric motor are both connected with the control mainboard. The lifting device has the substantial effects that lifting is stabler, the operation is easy, overtravel of the lifting column can be avoided, and the safety of the lifting device is improved.
