    摘要： The present invention provides an apparatus for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, said apparatus comprising:
    a blade guard (120) configured to generally cover the portion of the blade extending above the table top, and being pivotally mounted to enable a work piece to be moved into a cutting position by the blade; and
    a quick release assembly (30) that attaches said blade guard to a riving knife positioned rearwardly of the blade and attached to the saw, said assembly having a mounting portion (130) and a lever (136) that is movable between a release position and a holding position, said blade guard being removable from said riving knife when said lever is in its release position.

    摘要： The present invention provides a kickback prevention apparatus for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, the blade being configured to cut a work piece as the work piece is moved from a forward position to a rearward position, and an elongated riving knife mounted to the saw rearwardly of the blade, said apparatus comprising:
    a bracket having at least one pivot shaft for pivotally supporting at least one elongated kickback arm, with the arm having at least one sharp surface for engaging a work piece to prevent reverse movement of the work piece during a cutting operation;
    a quick release assembly operatively associated with said at least one pivot shaft for attaching said apparatus to the riving knife, said assembly having a mounting body that is movable on said at least one pivot shaft between a release position and a holding position, said apparatus being removable from the riving knife when said mounting body is in its release position.
