The invention discloses a tensioning sleeve. The tensioning sleeve has the beneficial effects that when a shaft and a wheel hub are needed to be locked and fixed, inner ring sleeves sleeve the shaft, outer ring sleeves is located in inner holes of the wheel hub; screw rods are rotated so that two taper sleeves move towards each other in the axial direction of the taper sleeves to reduce the distance, the two taper sleeves are matched with tapers of the two ends of the inner wall of the corresponding outer ring sleeve and tapers of the two ends of the outer wall of the corresponding inner ring sleeve, so that the taper sleeves enables the inner ring sleeves to contract in a circumferential direction to clamp the shaft, and meanwhile, the taper sleeves enables the outer ring sleeves to expand in the circumferential direction to be tensioned in the inner holes of the wheel hub; and the screw rods are rotated in the reverse direction, the distance between the two taper sleeves is gradually increased, the corresponding outer ring sleeve and the corresponding inner ring sleeve are restored to the original state under elastic actions of the inner ring sleeve and the outer ring sleeve, and the crew rods can be loosened. The tensioning sleeve is reliable in connection, convenient to dismount and mount and free of damage to the shaft and the wheel hub.
