• a riving knife body disposed between the holder and the clamping plate and having
• a knife slot formed through two opposite sides of the riving knife body;
• a handle disposed at a side of the clamping plate facing away from the holder, the handle pivotally connected to the clamping plate, the handle being pivotable around a pivot axis and relative to the clamping plate, and the handle having
• a first side;
• a second side opposite to the first side of the handle;
• a curved hole extending around the pivot axis and having a locked end and an unlocked end;
• a stage surrounding the curved hole, formed at the first side of the handle, and the stage having
• a lower step being adjacent to the unlocked end of the curved hole;
• an upper step being adjacent to the locked end of the curved hole;
• and
• a thickness from the upper step to the second side of the handle being larger than a thickness from the lower step to the second side of the handle;
• a fastener assembly connected to the holder, the riving knife body, the clamping plate, and the handle, and the fastener assembly comprising:
• a connecting rod mounted through the holder, the knife slot of the riving knife body, the clamping plate, and the curved hole of the handle;
• a positioning flange disposed at an end of the connecting rod and disposed at one of the first side and the second side of the handle that faces away from the holder;
• and
• an elastic pressing element sleeved on the connecting rod, disposed between the positioning flange and the handle, and configured to push the handle toward the clamping plate;
• wherein
• the handle has a locked position and an unlocked position;
• when the handle is in the locked position, the fastener assembly is located at the locked end of the curved hole of the handle, and the elastic pressing element is located between the positioning flange and the upper step of the stage of the handle;
