    • A guide to align a cutting or routing tool along a straight line has a stationary support fixed relative to the work and has arm-like linkage between the support and a hand-held tool or instrument. A first end-member of the first parallelogram frame is pivoted to the stationary support, preferably in conjunction with an arcuate angle indicator. Pivoted to this first end-member is a first parallelogram frame consisting of a pair of equal, parallel, arm-members which are pivoted to a pair of tangent identical rollers of a diameter equal to the effective distance between pivot centers of the first end-member. Means, such as bands around the rollers, insure that they revolve in opposite directions the same amount and remain tangent as the first arms move in parallelism. Extending from the center of each roller is one of a second pair of equal, parallel arms of the second frame which are pivoted to a final end-member of the same effective length as the first and the common end-members. The rollers thus constitute an elbow joint for the arm-like device. The final end-member of the second frame is fixed to the tool or to a guide against which the tool or instrument is aligned. One angle of movement of the first arm-members relative to their fixed end results in two angles of movement of the second arm-pair relative to the coupling mechanism. With the first end-member held in constant alignment to the work, movement of the tool or instrument is restricted to a predetermined straight line.
    • 沿着直线对准切割或布线工具的引导件具有相对于工件固定的固定支撑件,并且在支撑件和手持工具或工具之间具有臂状连接。 第一平行四边形框架的第一端部构件优选地与弓形角度指示器一起枢转到固定支撑件。 枢转到该第一端部构件的是第一平行四边形框架,该平行四边形框架由一对相等的平行的臂构件组成,该平行四边形框架枢转到直线等于第一端部构件的枢转中心之间的有效距离的一对切线相同的辊子, 会员。 手段,如滚筒周围的带,确保它们沿相反方向旋转相同的数量,并保持切线,因为第一臂平行移动。 从每个辊的中心延伸的是第二框架的第二对相等的平行臂中的一个,其枢转到与第一和共同的端部构件相同的有效长度的最终端部构件。 因此,辊构成了用于臂状装置的肘关节。 第二框架的最终端部件固定到工具或工具或仪器对准的导向件上。 第一臂部件相对于其固定端部的一个移动角度导致第二臂对相对于联接机构的两个移动角度。 当第一端构件保持与工件一致的对准时,工具或仪器的运动被限制在预定的直线上。
