Abstract

An electric saw device includes a first saw blade and a second saw blade. The first and the second saw blades are respectively driven by a small transmission shaft and a large transmission shaft to rotate in opposite directions. A round rib is disposed on an inner end surface of the first saw blade, and at least three recessed holes are arranged in a top end surface of the round rib at equal angle intervals. A steel ball is accommodated in each of the recessed holes, and protrudes out of the recessed hole. Protruding ends of the steel balls urge against an inner surface of the second saw blade, so as to limit a distance between the first saw blade and the second saw blade, and form a rolling friction when the first and the second saw blade rotate in the opposite directions. Further, a power output shaft of the electric saw device is joined with the small transmission shaft of the first saw blade through a key connection structure, so as to ensure that the saw blades do not tilt after installation.
