Sägeblattaufspannvorrichtung für ein motorisiertes Werkzeug

摘要

A saw blade clamping arrangement 12 particularly for power reciprocating saws and similar tools 10 having a reciprocating drive shaft 16 connected to a cutting member such as a saw blade 14 includes a clamping member 40 movable relative to the drive shaft 16 between a clamped position and a release position. A threaded fastener 42 passes through an aperture 56 formed in a portion of the clamping member 40 and functions to move the clamping member 40 to its clamped position upon selective rotation. A sleeve 44 surrounds the threaded fastener 56 for rotation therewith. When the sleeve 44 is biased against the clamping member 40 through the force of a biasing member 76, opposing surfaces 72 and 74 prevent rotation of the sleeve 44.
