摘要：<p>O A hand tightenable chuck for holding a cutting implement in place uses two screw systems (22, 32 and 24, 44) to achieve the proper degree of tightness. The first system (22, 32) providing a coarse tightening or pinching of the shaft (100) of the cutting implement and the second (24, 44) providing a clamping action. The combination of two screw systems eliminates the need for a key to tighten the chuck.</p>
