摘要：
A quick release chuck device (10) includes a body member (12) and a device (14) for attaching the body member (12) to a drive spindle (76). A longitudinal bore or recess (22) is defined in the body member (12) and a resilient coiled member gripping device (56) is disposed in the longitudinal recess (22). The coiled member (56) defines an inner diameter bore (57) for receipt of a tool shank (82) inserted therein. A device (42) is provided for variably coiling the coiled member gripping device (56) within the longitudinal recess (22) thereby causing the inner diameter bore (57) to constrict and grip upon a tool shank (82) inserted therein.
