The invention provides a synchronous lifter, and relates to the technical field of lifters. The synchronous lifter comprises: a plurality of lifting units, wherein the lifting units are sequentially arranged at intervals, each lifting unit comprises a gear box, a transmission nut is movably arranged in the gear box and used for rotating along the axis of the transmission nut, a transmission lead screw matched with the transmission nut in a threaded mode is arranged in the transmission nut in a penetrating mode, and the transmission lead screw penetrates through the gear box; and transmission assemblies, wherein the transmission assemblies are arranged between the adjacent lifting units, the transmission assemblies are in transmission fit with the transmission nuts in the two lifting units, and a transmission structure composed of the multiple transmission assemblies drives the multiple lifting units to ascend and descend synchronously. The synchronous lifter has the functions of preventing a loaded heavy object from falling and increasing the torque.
