    摘要： A riving knife mounting assembly is provided that rigidly and accurately positions the riving knife relative to the cutting blade by way of a simple and intuitive mechanism. Interaction between a clamping plate and a locking plate engage opposite sides of the riving knife to hold the riving knife in place, and provides a sensible indication that the two components are properly mated. A cam lever assembly allows loosening or tightening the clamping plate and locking plate together about the riving knife by simply rotation of the lever. A spring assembly maintains pressure on the riving knife even in the loosened position to maintain proper positioning of the components. The clamping plate is part of a mounting bracket that is mounted to a motor arm movable with the drive assembly, and includes adjustment screws for adjusting the orientation of the riving knife relative to the cutting blade in multiple degrees of freedom.

    摘要翻译： 提供了一种劈刀安装组件，其通过简单直观的机构将劈刀相对于切割刀片刚性且精确地定位。 夹板和锁定板之间的相互作用与劈刀的相对侧接合，以将劈刀固定就位，并提供两个部件适当配合的合理指示。 凸轮杆组件允许通过杠杆的简单旋转将夹板和锁定板围绕劈刀松开或拧紧在一起。 即使在松动的位置，弹簧组件也能保持劈刀上的压力，以保持部件的正确定位。 夹板是安装到可与驱动组件一起移动的电动机臂上的安装支架的一部分，并且包括用于以多个自由度调节劈刀相对于切割刀片的定向的调节螺钉。

    摘要： A table-cutting type protective cover of a composite saw comprises a follower plate, a left and right auxiliary cover plate and a movable cover body. The follower plate and the movable cover body are respectively hinged to the two ends of the left and right auxiliary cover plate. The table-cutting type protective cover can be opened neatly, prevent the saw blade from being exposed and increase the safety of the saw.

    摘要： A power tool (20) having an integrated control system includes a workpiece supporting surface (24), a cutting instrument (28) extendable above the workpiece supporting surface, a guard assembly (52) securable above the workpiece supporting surface for covering at least a portion of the cutting instrument, the guard assembly having a first state for providing a first level of protection and a second state for providing a second level of protection, a motor coupled with the cutting instrument, and a power switch operable for starting the motor for driving the cutting instrument. The power tool includes a control system (100) in communication with the guard assembly for determining if the guard assembly is in the first state or the second state. Before the motor is started, the control system (100) automatically disables the motor if it determines that the guard assembly is in the second state. The control system includes a bypass switch (126) for enabling starting of the motor when the guard assembly is in the second state.

    摘要： The present invention provides an apparatus for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, the blade being configured to cut a work piece as the work piece is forwardly moved from a forward position to a rearward position, said apparatus comprising:
    a riving knife mechanism (22) releasably mounted to the saw rearwardly of the blade, and being configured to be adjustable between retracted and extended positions relative to the blade, the mechanism having an elongated relatively thin knife (34) that is mounted substantially in the same plane as the blade, the outer upper end of said knife being capable of being positioned below the table top when in its retracted position and extending to an elevation at least approaching the upper reach of the blade when in its extended position.
