The other end of the transmission shaft extending to the front of the drive forms as a pincer-like slot, and a worm is disposed between the two ends. One end of a gear set having a plurality of gears drives a clamping unit, and the other end rotates a roller. A worm wheel is disposed on one of the gears in the middle of the gear set and is engaged with the worm with self-locking so that the transmission shaft can be rotated by hand to eject a disk.
