ABSTRACT:
A power saw is provided with a mechanism for shielding the circular saw blade of the power saw. The shielding mechanism is composed of a first shield, a second and third shield rotatable relative to said first shield, a pivot, a master connection rod, and a slave connection rod. The master connection rod is fastened with the pivot and second shield while the slave connection rod is fastened with third shield and the master connection. The second shield and third shield can be extracted to shield the circular saw blade of the power saw at such time when the circular saw blade is moved away from the work piece. The second shield and third movable shield are retracted to expose the circular saw blade at such time when the circular saw blade is moved toward the work piece.
