The invention discloses a synchronous expansion and contraction guide ring for a sleeve. The synchronous expansion and contraction guide ring is provided with a first end surface and a second end surface in the axial direction, wherein the diameter of the first end surface is larger than that of the second end surface, the synchronous expansion and contraction guide ring comprises a plurality of fan-shaped bodies which are arranged in the circumferential direction of the synchronous expansion and contraction guide ring, the plurality of fan-shaped bodies jointly define the synchronous expansion and contraction guide ring in a surrounding mode, an elastic element is connected between every two adjacent fan-shaped bodies so that the diameter of the synchronous expansion and contraction guidering can be relatively increased or reduced. The synchronous expansion and contraction guide ring for the sleeve has the advantages that the hardness is relatively high, the friction coefficient is relatively low, moreover, the synchronous expansion and contraction guide ring can expand and contract along with expansion and contraction of the sleeve so that the problem of failure of inserting ofa coil due to the fact that the steel coil is inserted into the sleeve to generate interference can be effectively solved.
