摘要

A chuck device includes a body having a slot in a first end thereof and a hole is defined radially in the body and communicates with the slot. A spring is mounted to the body and is biased between a stepped shoulder on the body and a movable clamp connected to the body. A connection rod is connected to a second end of the body. A positioning pin is movably inserted in the hole and an end of the positioning pin extends from the hole and has a tapered periphery. A sleeve is slidably mounted to the body and has a first tapered inner periphery for being matched with the tapered periphery of the positioning pin. A second tapered inner periphery is defined in a second end of the sleeve so as to push the movable clamp when sliding the sleeve by compressing the spring.
