According to the spiral elevator, an input worm shaft rotates and drives a worm gear to rotate, and the worm gear is connected to a lifting lead screw through threads so that the lifting lead screw can move in the axial direction; the shell sleeves the outer sides of the lifting lead screw and the worm gear; the clutch body is slidably arranged on the outer side of the lifting lead screw in a sleeving mode, and the clutch body is selectively and axially fixed to the worm gear. One end of the ratchet wheel is fixed to one end of the lifting lead screw, the other end of the ratchet wheel is fixed to the anti-rotation body, and a plurality of key grooves are formed in the anti-rotation body at equal intervals in the circumferential direction. The anti-rotation key is axially arranged on the inner wall of the shell and can be clamped with the key groove; the convex rattan body is arranged on the shell in a manner of being capable of popping up inwards, and the convex rattan body is selectively clamped with the ratchet wheel; the ratchet wheel is selectively and axially fixed to the clutch body, and the convex rattan body is arranged on the upper side of the anti-rotation key. The invention has the characteristic of satisfying movement or rotation.
