A low mounting distance raising column, comprising a drive unit, a lifting tube, and a transmission assembly. The lifting tube includes a first tube, a second tube, a third tube, a fourth tube, and a fifth tube, a lower end of the fifth tube being secured on the drive unit. The transmission assembly includes a first screw rod, a second screw rod, a third screw rod, and a fourth screw rod, an output end of the drive unit being in transmission fit with the first screw rod and configurable to drive the first screw rod to rotate. A lower end of the second screw rod is provided with a first nut in threaded transmission connection with the first screw rod, a lower end of the third screw rod is provided with a second nut in threaded transmission connection with the second screw rod, a lower end of the fourth screw rod is provided with a third nut in threaded transmission connection with the third screw rod, and a lower end of the first tube is provided with a fourth nut in threaded transmission connection with the fourth screw rod. Since the adjacent screw rods are in threaded transmission connection and respective nut is provided between every two adjacent screw rods, a transmission assembly which is compact in both axial and radial directions is achieved, thereby implementing a low retracted-height, large stroke-length lifting column.
