The invention relates to the technical field of bearing installation accessories, and discloses a reinforced adapter sleeve which comprises a bearing and a taper sleeve, the taper sleeve is sleeved with the bearing, the right end of the taper sleeve is sleeved with a large nut in a threaded mode, the outer wall of the taper sleeve is slidably sleeved with a clamping piece, and the clamping piece is pressed on an inner wheel of the bearing. An elastic inner layer is fixedly installed on the inner wall of the taper sleeve, a taper sleeve body is made of high-strength abrasion-resistant alloy, the elastic inner layer is made of elastic memory alloy, and by means of the design, pre-deformation can be conducted by heating the taper sleeve and the elastic inner layer during installation, and when external force impact or temperature change occurs, the holding force can be adjusted in a self-adaptive mode, so that the service life of the taper sleeve is prolonged. Loosening is effectively prevented, an anti-falling part is arranged at the right end of the taper sleeve and used for preventing the large nut from falling off and loosening from the taper sleeve, a jacking part is arranged at the left end of the taper sleeve and can jack the taper sleeve, and the connection stability between the taper sleeve and the optical axis and the bearing is enhanced.
