Claim:
A power saw comprising: a table configured to receive a workpiece; a saw blade and motor assembly; a linear guide mechanism operatively connected to said table and being configured to pivotally support said saw blade and motor assembly, said linear guide mechanism enabling movement of said saw blade and motor assembly along a predetermined linear path in a forward or a rearward direction at a constant level; said linear guide mechanism including a first link and a second link pivotally connected by a first hinge connection, said first and second links enabling said linear guide mechanism to maintain said saw blade and motor assembly at said constant level; and a locking mechanism fixed to said first hinge connection for locking said linear guide mechanism to prevent said saw blade and motor assembly from being moved along said predetermined linear path, wherein said locking mechanism includes an elongated wedge portion configured to be pivotally inserted in a space created between opposing ends of said first and second links at said first hinge connection, to prevent said first and second links from pivoting about said first hinge connection relative to each other.
