Algning mechanism for hand-held power saw

摘要

An aligning mechanism for a hand-held circular saw has a base adapted to be attached to the circular saw. The base has an upper surface and a lower surface. At least two paddles are pivotally mounted about a horizontal axis and movable in unison between a deployed position and an undeployed position. Each paddle when in its deployed position extends below the lower surface of the base and is capable of contacting an edge of the workpiece so that the saw blade is aligned in a predetermined position with respect to the edge. The paddles move in unison toward their undeployed positions as the saw blade engages the workpiece while maintaining the predetermined alignment between the saw blade and the edge.
