Abstract:
A chuck for detachably fixing an object to a rotatable base, said chuck comprising:(a) a clamp having opposite ends; (b) a resilient member connected to one end of the clamp; and (c) a support detachably mounted to the rotatable base at the other end of the clamp; wherein the clamp is pivotally mounted to the support; wherein the resilient member is resiliently deformed when the support is mounted to the rotatable base; wherein the resilient member is configured to apply a force to said one end of the clamp, thereby causing the other end of the clamp to pivot downward to apply a pressing force against the object, which is disposed between the rotatable base and said other end of the clamp; and wherein, when the rotatable base rotates, a centrifugal force acts on the clamp and increases the pressing force against the object.
