Abstract
An optical disc clamping device is provided. A driving bar is moved away from a center hole to synchronously drive a first linking bar and a second linking bar. A first pivotal rod and a second pivotal rod are respectively driven by the first slider and the second slider to move towards the center hole to drive a carrier which carries a chucking disk disposed thereon to contact a spindle motor. A suppresser is fixed at the rim of the center hole to press on the chucking disk to clamp the disc stably.
