An elevating device includes an upper connecting seat, a lower connecting seat, at least one scissors unit, and a hoist. The lower connecting seat is vertically movable relative to the upper connecting seat between an upper position and a lower position. The at least one scissors unit interconnects the upper connecting seat and the lower connecting seat. The hoist is operable to release a rope to thereby move the lower connecting seat to the lower position and convert the at least one scissors unit to the expanded state, and is further operable to retract the rope to thereby move the lower connecting seat to the upper position and convert the at least one scissors unit to the contracted state.
