Hand tightenable device for holding a cutting implement |
摘要 |
A hand tightenable chuck for holding a cutting implement in place has been developed. The chuck uses two screw systems to achieve the proper degree of tightness; a first system providing a coarse tightening or pinching of the shaft and a second providing a clamping action. The combination of screw systems eliminates the need for the key used to tighten conventional chucks.
