The invention relates to a lead screw with an upper limiting switch. The lead screw comprises a lead screw upper part and a lead screw lower part which are connected through a threaded rod, the end of the threaded rod is provided with a first gear and a second gear, and the first gear is engaged with the second gear. The lead screw is provided with the upper limiting switch, the upper limiting switch comprises a blocking piece, an upper limiting switch assembly and a sliding seat, and the sliding seat is provided with an upper limiting moving rod and a pressing rod. The upper limiting switch assembly comprises an upper limiting microswitch, and the upper limiting microswitch is provided with an upper limiting contact piece. The lead screw is simple in structure and high in sensitivity, the failure rate is almost zero, and the lead screw contributes to stable lifting and effective limiting of a lifting platform.
