A bayonet shaped fastener, which fastens and unfastens the collet (3) to/from the chuck (2) without a tool, is provided. Thereby, the present invention has low structural costs and high functionality. The clamping device comprises: an operation ring (14) in which the bayonet shaped fastener is manually operated; and a body tube which is connected to the operation ring (14) and fixes the collet (3) to the chuck (2). |
