Disclosed are a lifting column transmission assembly and a lifting column that includes an inner tube, the transmission assembly includes: an exteriorly threaded hollow spindle, a transmission screw, a sleeve fitted over the hollow spindle, a guide tube limited in the sleeve, and an actuating device actuating the guide tube to rotate, the guide tube and the hollow spindle being synchronously rotatable and being axially expandable and contractable relative to each other; the transmission screw and the hollow spindle being synchronously rotatable and being axially expandable and contractable relative to each other; the actuating device is disposed in the inner tube and securely mounted to an upper end of the sleeve; and a lower end of the sleeve is securely connected with a first transmission nut that is thread-fitted with the hollow spindle, the first transmission nut being securely coupled to the inner tube, the upper end of the sleeve being movably disposed. Vibration generated by the actuating device is transmitted to the first transmission nut via the sleeve, instead of being directly transmitted to a lifted platform on top of the inner tube, rendering a lighter vibration, a smoother transmission of the transmission assembly, and a lighter vibration during lifting of the lifting column.
