Abstract: A riving knife assembly has a holder, a clamping plate, a riving knife body disposed between the holder and the clamping plate, a handle pivotally connected to the clamping plate, and a fastener assembly connecting the holder, the riving knife body, the clamping plate, and the handle. The handle has a curved hole and a stage surrounding the curved hole and having a lower step and an upper step. The fastener assembly includes a connecting rod, a positioning flange, and an elastic pressing element. When the handle is in a locked position, the elastic pressing element is located between the positioning flange and the upper step of the stage to clamp the riving knife body. When the handle is in an unlocked position, the elastic pressing element is located between the positioning flange and the lower step of the stage to release the riving knife body.

Abstract: A sawdust collection system includes a sawdust duct secured in a saw blade housing and having an enlarged portion formed on a front end thereof. A sawdust chute is partially pivotally received in a lower portion of the enlarged portion of the sawdust duct such that the sawdust chute can be swung relative to the sawdust duct. A first stopper laterally outwardly extends from a bottom of the sawdust chute and a torsion spring is mounted between the sawdust duct and the sawdust chute to prevent the sawdust chute from a vibration during operating. A second stopper laterally outwardly extends from a top of the sawdust chute. The second stopper selectively abuts a distal edge of the enlarged portion for limiting the moving range of the sawdust duct.

Abstract: A feeding device for a table saw includes a sliding board slidably mounted on one side of a worktable of the table saw and having a moving direction corresponding to a saw blade. The sliding board includes two grooves defined in two opposite sides thereof and respectively parallel to the moving direction of the sliding board. A moving seat is selective slidably mounted on one side of the sliding board. A pushing rod is laterally slidably mounted to the moving seat and has a first side forming a pushing face for abutting against a datum of a workpiece. A first locking device and a second locking device respectively extend through the pushing rod and the moving seat to selectively hold the pushing rod and the moving seat in place for confirming a cutting angle of the workpiece.
