Zusammenfassung:	The utility model relates to a shell retreating combination tool and belongs to the field of mechanical assembling. The shell retreating combination tool comprises a sleeve ring, a clamping ring and a pulling chain. Inner threads are machined on the inner ring face of the sleeve ring, and an annular position clamping groove is formed in the middle of the outer ring of the sleeve ring. The clamping ring is an annular combination piece composed of two semi-annular split pieces. A pin hole is formed in the connection portion of the two split pieces. Connecting blocks with connecting holes are arranged in the axial direction of the two semi-annular split pieces of the clamping ring in an outward-extending mode. The two ends of the pulling chain are fixed with the connecting blocks on the two semi-annular split pieces of the clamping ring. The two semi-annular split pieces of the clamping ring are arranged in the annular position clamping groove of the sleeve ring in a sleeved mode. The two semi-annular split piec
