Portable miter saws
摘要:
A portable miter saw for cross-cutting and mitering elongated workpiece has a mechanism interlocked with the turntable for shutting the saw blade clearance gap in the guide fence. The mechanism is provided with a pair of shutter plates slidable on the guide fence and an interlocking piece connected to the shutter plates and movable in operative association with the turntable so as to linearly displace the shutter plates upon rotation of the turntable to selectively change the cutting angle of the saw blade.
