    • A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used. The pair of movable fences are located on opposite sides of a working tool such as a saw blade. A fixed clamping arrangement is associated with each movable fence and provides a single point actuation member for each movable fence to clamp the movable fence to the fixed fence such that the movable fence is vertically aligned and flush with the fixed fence. In one embodiment, each movable fence is provided with a gap-filling flap which is pivotably secured to the movable fence to be movable between a lower and an upper position. In its lower position, the gap-filling flap minimizes the gap between the movable fence and the working tool. In its upper position, the gap-filling flap provides additional support when working with taller or thicker workpieces. The workpiece-supporting fence further includes a fence position indicator which allows for the positioning of one or both of the movable fences for providing clearances for a specific miter and/or bevel cut. In addition, the workpiece-supporting fence incorporates a detent system for locating the fence at tone or more of the most popular miter and/or beveling settings.
    • 工件支撑栅栏具有可移动地连接到固定围栏的一对可移动栅栏,固定栅栏固定到使用栅栏的装置的基部。 一对可移动围栏位于诸如锯片的工作工具的相对侧上。 固定的夹紧装置与每个活动围栏相关联并且为每个可移动围栏提供单点致动构件,以将可移动围栏夹紧到固定围栏,使得可移动栅栏垂直对准并与固定栅栏齐平。 在一个实施例中,每个活动围栏设置有间隙填充折片,该间隙填充折片可枢转地固定到可移动围栏,以在下部和上部位置之间移动。 在其较低的位置,间隙填充翼片使可移动围栏和作业工具之间的间隙最小化。 在其上部位置,间隙填充翼片在使用较高或较厚的工件时提供额外的支撑。 工件支撑围栏还包括挡板位置指示器,其允许定位一个或两个可移动挡板,以提供用于特定斜角和/或斜切的间隙。 此外,工件支撑围栏包括用于将篱笆定位在音调或更多最受欢迎的斜角和/或斜面设置的制动系统。
