ABSTRACT:
A removable attachment for use with a hand-held tool is disclosed. The tool comprises a housing and a cutting blade mounted therein for continuous reciprocating movement during operation. The attachment comprises a work piece receiving member pivotally mounted to the tool housing. An adjustable clamping member is pivotally mounted to the work piece receiving member. An adjuster, movable between an operable and a non-operable position, is operably connected to the clamping member for adjusting the clamping member so as to clamp a work piece positioned on the work piece receiving member for operation thereon by the cutting blade. A quick release mechanism comprising a sliding member, movable between a first position and a second position, is provided for quickly moving the adjuster between its operable and non-operable positions. A rotatable cam is operatively connected with the sliding member; rotation of the cam causes the sliding member to move from the first position to the second position thereby causing the sliding member to move the adjuster into the operable position. In the operable position, the adjuster is operably connected to the clamping member, and in the non-operable position, the clamping member and the adjuster are freely movable allowing the operator to quickly position a work piece in the clamp or remove a cut work piece.
