A mechanical lifting rod with multiple lead screws comprises a pipe body and a driving device, and the pipe body is provided with multiple circular pipes, wherein the axes of the pipes are on the same straight line, and the pipes are sleeved together in the mode that the diameters of the pipes change from large to small; an axial guide key is arranged on the outer wall of each circular pipe, the inner circumference of each circular pipe upper end upper sleeve is provided with guide slots, the driving device comprises the multiple circular pipe lead screws which are arranged in the circular pipes, the outer circumference of each circular lead screw is provided with an axial plane, each lower end pipe orifice is provided with pin holes, an arch-shaped pin block which can slide on the axial plane of the adjacent inner side lead screw is embedded in each pin hole, a circular-ring-shaped lower sleeve is connected between each circular pipe and the lower end of the corresponding circular pipe lead screw, a bearing is arranged on the upper section of each lower sleeve inner hole, a nut is arranged on the lower section of the lower sleeve inner hole, and each lead screw is meshed with the nut of the adjacent lower sleeve. When the mechanical lifting rod with the multiple lead screws is lifted up or dropped down, the multiple circular pipes are lifted up or dropped down synchronously, and the used time of lifting or dropping is shorter; the adjacent circular pipe lead screws of the driving device of the mechanical lifting rod with the multiple lead screws are mutually connected and transmit torque through the arch-shaped pin blocks and the radial pin holes, the structure is simple, and the mechanical lifting rod with the multiple lead screws can be lifted up to any height below the highest height.
