    • A saw blade clamping arrangement particularly for power reciprocating saws and similar tools having a reciprocating drive shaft connected to a cutting member such as a saw blade includes a clamping member movable relative to the drive shaft between a clamped position and a release position. A threaded fastener passes through an aperture formed in a portion of the clamping member and functions to move the clamping member to its clamped position upon selective rotation. A sleeve surrounds the threaded fastener for rotation therewith. When the sleeve is biased against the clamping member through the force of a biasing member, opposing surfaces prevent rotation of the sleeve.
    • 特别是用于动力往复锯的锯片夹持装置和具有连接到诸如锯片的切割构件的往复式驱动轴的类似工具包括可在夹紧位置和释放位置之间相对于驱动轴移动的夹紧构件。 螺纹紧固件穿过形成在夹紧构件的一部分中的孔,并且用于在选择性旋转时将夹紧构件移动到其夹紧位置。 套筒环绕着螺纹紧固件与其一起旋转。 当套筒通过偏置构件的力而抵靠夹紧构件偏置时,相对表面防止套筒旋转。
