The present Invention disclosed a transmission assembly, which relates to the field of transmission devices. Solved is a technical problem that a same transmission assembly cannot be adapted to both orderly-assembling and reversely-assembling. A technical solution for solving the technical problem mainly comprising a hollow spindle, of which the outer wall is provided with an outer thread; a transmission worm disposed in the hollow spindle; a first transmission nut which is thread-fitted with the transmission worm, wherein the hollow spindle is rotatably positioned relative to the first transmission nut in an axial direction, and an external portion of the first transmission nut is provided with a locking structure for limiting the first transmission nut from rotating; a second transmission nut which is thread-fitted with the hollow spindle; a bushing which is bushed outside of the hollow spindle, the second transmission nut being fixedly connected with the bushing; and a guide tube which is rotatably limited in the bushing; further disclosed a lifting column having the transmission assembly. Irrespective of whether the lifting column is orderly assembled or reversely assembled, the transmission assembly is always adaptable, thereby reducing manufacturing costs.
