摘要： A shearing tool for cutting cement siding which includes upper and lower blade holders. Each blade holder has first and second ends and an elongated slot extending substantially therebetween. The blade holders are positioned so that the slots face each other and are substantially aligned. Upper and lower blades are removably mounted in the slots of the upper and lower blade holders, respectively. The upper and lower blades each have a relatively narrow cross-sectional width and a cutting edge. When positioned in the slots of the blade holders, the upper and lower blades define a cutting plane in which the cutting edges are substantially aligned and face each other. A number of links are operatively connected to the ends of the blade holders so that either the upper or lower blade holder can move towards the other in the cutting plane. The links are configured so that the cutting edges of the blades are substantially parallel upon engaging a cement siding workpiece in a closed position, and an actuator is connected to at least one of the links for moving either the upper or lower blade holders towards the other to engage the upper and lower blades with the siding in the closed position.

摘要翻译： 用于切割水泥壁板的剪切工具，包括上下刀片支架。 每个刀片保持器具有第一和第二端以及基本上在其间延伸的细长槽。 刀片保持器被定位成使得槽彼此面对并且基本上对准。 上刀片和下刀片分别可拆卸地安装在上和下刀片支架的槽中。 上下叶片各自具有相对窄的横截面宽度和切割刃。 当定位在刀片保持器的槽中时，上刀片和下刀片限定切割平面，切割刃基本上对齐并相对。 许多连接件可操作地连接到刀片保持器的端部，使得上刀片保持器或下刀片保持器可以在切割平面中朝着另一个移动。 链节被构造成使得叶片的切割边缘在将水泥壁板工件接合在关闭位置时基本上平行，并且致动器连接到至少一个连杆，用于将上部或下部刀片保持器朝着另一个移动 以将上部和下部刀片与侧板接合在关闭位置。
