Abstract:
1. A kickback-inhibiting device for inhibiting a workpiece from being lifted up by a cutting blade of a cutting device, wherein the cutting blade partly extends upward from an upper surface of a table used for placing the workpiece thereon, the kickback-inhibiting device comprising: a pair of kickback-inhibiting members each movable between an operative position where each kickback-inhibiting member is operable to engage the workpiece from an upper side in order to inhibit the workpiece from being lifted up, and an inoperative position where each kickback-inhibiting member is positioned upwardly away from the workpiece so as not to interact with the workpiece; a holding device arranged and constructed to hold the pair of kickback-inhibiting members in the inoperative position; and a riving knife disposed on a rear side of the cutting blade, as viewed in a cutting direction of the workpiece, and aligned with the cutting blade, wherein: the pair of kickback-inhibiting members are positioned on opposite sides of the riving knife and are vertically pivotally supported on the riving knife about a pivotal axis; and the holding device comprises: the retaining pin and the retaining holes are positioned away from the pivotal axis with respect to a radial direction of the pivotal axis such that the retaining pin and the retaining holes are positioned at substantially a same radial distance from the pivotal axis; and the retaining pin has opposite ends, each end engageable with a corresponding one of the retaining holes each of the kickback-inhibiting members in the inoperative position, only when each of the kickback-inhibiting members has pivoted upward to reach the inoperative position.
