PROBLEM TO BE SOLVED: To position a sleeve in such a manner that the sleeve can be fixed and is rotatable.SOLUTION: A sleeve bracket assembly comprises a frame 10 and a plurality of first sleeve mounts 21. The frame includes a first sleeve track 13 having a groove 133. Each of the first sleeve mounts includes a hollow positioning button 212 having telescopic projection 2123 or flange which projects from a stem 211 and the top surface of the stem. The stem of each of the first sleeve mounts or the positioning button has a circular section, whereby a sleeve is rotatable. The projection or flange can position the sleeve so as to be able to fix the sleeve. Consequently, the sleeve bracket assembly firmly positions the sleeve and enables the sleeve to be rotatable. |
