[0015] The beneficial effects of the utility model are as follows:

[0016] This invention involves inserting a cartridge into the central through-hole of an optical disc. Multiple outer cartridges slide at the bottom of the cartridge, causing them to extend and retract, which in turn moves a connecting block. This moving block to a position on the bottom of the disc away from the central through-hole causes a second rubber block to move, bringing its top into contact with the bottom of the disc. Multiple movable cartridges slide at the bottom of a fixed cartridge, moving them closer to one side of the disc, which in turn moves a first rubber block closer to that side, bringing its bottom into contact with the top of the disc. This, combined with the second rubber block, clamps the disc, allowing it to be moved and gripped. This device is not only simple in structure but also highly stable when gripping the disc, preventing it from falling. It solves the problems of existing devices being overly complex, unable to guarantee stable disc positioning, having high maintenance costs, and being prone to disc drop and damage during use, making them inconvenient to use.
