摘要： A scroll saw includes upper and lower driving arms, a saw blade, a blade retaining unit, push rod, a biasing unit, and an actuating unit. The blade retaining unit includes a pivot seat mounted pivotally on a distal end of the upper driving arm, and an upper blade holder mounted on the pivot seat. The pivot seat is pivotable relative to the upper driving arm from a first position, where the upper blade holder engages an upper blade end of the saw blade, to a second position, where the upper blade holder disengages from the upper blade end. The biasing unit provides a biasing force that pivots the pivot seat to the first position. The actuating unit provides a pressing force on the push rod to push the pivot seat to pivot to the second position so as to permit release of the saw blade.

摘要： The invention pertains to a saw, in particular to a jig saw or scroll saw, with a saw blade which is driven by a force acting on a parallelogram of rods. A saw blade is attached to a connecting shank which joins two longitudinal side arms. The two longitudinal side arms are designed to move in their longitudinal direction. On at least one of the two longitudinal side arms a guide element in the form of, for example, a turning roller, is positively guided against a stationary guide surface which is at an angle, preferablye an acute angle, to the connecting shank. As a result of this positive guidance, the backward movement of the saw blade from the cut edge during the return stroke is reduced to a desired value. Thus a jig saw of small size, but with a large stroke, can be realized in which the saw blade is guided parallel to the cut edge at all times but is moved back by a small amount from the cut edge during the return stroke.

摘要： A novel mounting assembly for use with a universal woodworking tool support system is the subject of the invention. First and second straight elongated support stanchions are received by tubular members of the universal tool support system. A scroll saw is mounted on top of these two straight stanchions. A drive train includes an eccentric drive for reciprocating the scroll saw arms and a concentric mass between the eccentric drive and the output of the prime mover is part of the universal tool support system. The concentric mass together with the straight support stanchions greatly reduces the vibrations which are transmitted through the drive train to the scroll saw framework.
