Abstract：
 The present invention relates to a multidisk type optical disk positioning and fastening mechanism, including fastening positioning element, drive element and support elemnt. The described fastening positioning element and drive element are coaxially-mounted on the support element. Said fastening positioning element is a cylindrical stepped body, and the intersected place of the stepped surface and cylindrical body has uniformly-distributed circular channels, and on the cylinder body and in the position corresponding to the circular channel an inverted-U-shaped through channel is cut, so that the intersected position of the cylinder body and steppen surface is formed into flexible hinge. Three pawls of upper portion of said drive element are inserted into the internal cavity of stepped body of lower portion of fastening positioning element, and matched with the inverted U-shaped thin sheet of lower portion of the cylinder body. The lower portion of drive element is a cylinder body, and the support element is made into a cup body. It possesses the advantages of compact structure, high positioning accuracy and high reliability, etc.
