Abstract: A seed crystal lifting device (100) and a single crystal furnace (200) are provided. The seed crystal lifting device (100) is applied in the single crystal furnace (200), including a frame (1), a cable pipe (4), and a driving component (5). The frame (1) is disposed at a top of the single crystal furnace (200). The cable pipe (4) is movably disposed on the frame (1), and a peripheral wall of the cable pipe (4) is configured to wind a seed crystal rope. The driving component (5) is disposed to the frame (1) and configured to drive the cable pipe (4) to rotate around an axis of the cable pipe (4) and slide along a vertical direction at the same time to wind and lift the seed crystal rope.
