A plug lid (5) for plugging the through hole (2) is connected with the inner wall of the through hole (2) in a threaded mode. The top of the plug lid (5) is provided with a groove (3), the bottom of the groove (3) is provided with a scratch (4) allowing a screwdriver to be inserted therein, and the groove (3) is covered by a soft plug (11). The length of the plug lid (5) is smaller than the depth of the through hole (2). The inner wall of the bottom end of the through hole (2) is fixedly provided with a connection plate (8) with an oil hole (9). The leather roller sleeve is simple in structure and ingenious in design. The plug lid (5) is taken down, and oil can be fed into the leather roller sleeve through an oil gun so as to overcome the defect of oil insufficiency of the leather roller sleeve.
