Abstract
A chuck for detachably fixing an object to a rotatable base, the chuck comprising (a) a support detachably mountable to the base, (b) a clamp having opposite ends, the clamp being pivotally mounted to the support between the ends of the clamp, and (c) a resilient member connected to one end of the clamp, the resilient member being resiliently deformed when the support is mounted to the base, which applies a force to the one end of the clamp, thereby causing the other end of the clamp to pivot downward, and apply a pressing force against an object disposed between the base and the other end of the clamp, wherein when the base rotates, centrifugal force acts on the clamp and increases the pressing force against the object.
Claims21
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.
A fixing structure for detachable mounting, comprising:
- a base having a dovetail type groove including a bottom and a top, formed along the base and whose cross-section is a substantially trapezoidal such that the groove top has a width less than a width of the groove bottom;
- and
- an object having an end with a block integrally provided at said end of the object and said block being insertable into said groove;
- wherein the object is rotatable with the block about an axis of the object, and the block is structured such that when the object is positioned at a first rotation angle position around the axis of the object, the block can be inserted into the groove and when the block is rotated from the first rotation angle position to a second rotation angle position, the block engages with the groove and thus further rotation of the block is prevented and the block cannot be removed from the groove at the second rotation angle position.
