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 table saw includes a suspension rod having a bottom face formed with a flattened face, and a motor gear box rotatably mounted on the suspension rod and having a top face formed with a recess. When the motor gear box touches the suspension rod, the flattened face of the suspension rod is received in the recess of the motor gear box, thereby reducing the vertical distance between the rotation shaft of the circular blade and the work table, so that the height of the circular blade protruding outward from the work table is increased, thereby increasing the cutting height of the circular blade, so that the circular blade may be used to cut a workpiece having a larger thickness, thereby increasing the cutting efficiency of the table saw.
Abstract translation: 台锯包括具有形成有平坦面的底面的悬架杆和可旋转地安装在悬架杆上并具有形成有凹部的顶面的马达齿轮箱。 当马达齿轮箱接触悬架杆时，悬挂杆的平坦面被容纳在马达齿轮箱的凹槽中，从而减小了圆形刀片的旋转轴与工作台之间的垂直距离，使得高度 从工作台向外突出的圆形刀片增加，从而增加圆形刀片的切割高度，从而可以使用圆形刀片来切割具有较大厚度的工件，从而提高台锯的切割效率。

Abstract: A wheeled stand for a table saw has a stand body, two wheels rotatably connected to the stand body, and a kickstand pivotably connected to the stand body. The stand body has a first side, a second side, an infeed side, and an outfeed side. The two wheels are disposed near the second side of the stand body. The kickstand disposed at the outfeed side of the stand body and has a folded position and an unfolded position in which the kickstand obliquely extends downwardly and away from the infeed side of the stand body. The kickstand can be unfolded and support the stand body at the outfeed side thereof during cutting a workpiece to prevent the wheeled stand from being tipped over.

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.
