Abstract

A lifting device with a cable management is provided. The lifting device includes: an outer pipe, an actuation mechanism, a linkage member, a cable, and a cable management component. The actuation mechanism is accommodated in the outer pipe and has a motor and a screw rod. The linkage member is accommodated in the outer pipe and mutually screw-fitted with the screw rod to operate, and moves relative to the outer pipe. The cable has a spiral coiled cable unit. A shaft core line in parallel with the screw rod is defined by the spiral coiled cable unit. The cable management component is disposed in the outer pipe and in parallel to the shaft core line. The spiral coiled cable unit is reeled on the cable management component. Accordingly, the cable may be stably positioned and the cable may be prevented from rubbing or being tangled with the screw rod.
