A miter saw includes a base having a peripheral wall, a table rotatably supported upon the base, and a miter angle lock. The miter angle lock includes a pin having a first end adjacent the peripheral wall and an opposite second end. The miter angle lock also includes a cam member engageable with the second end of the pin and movable between a locked position in which the first end of the pin is brought into frictional contact with the peripheral wall for locking the table relative to the base, and an unlocked position in which the first end of the pin is spaced from the peripheral wall of the base.

Miter saw

A miter saw including a base having a plurality of grooves formed in a bottom surface thereof, a table rotatable with respect to the base, a rotary indexing mechanism and a locking mechanism. The rotary indexing mechanism includes a body fixedly connected to and rotatable with the table and a protrusion provided on the body. The protrusion can be received within one of the plurality of grooves in the base and thereby angularly index the table at a desired position with respect to the base. The locking mechanism is operably coupled to the table and is configured to lock the table at the desired position. The miter saw has a more reasonable and practical structure that allows angular indexing and interlocking of the table with respect to the base to be accomplished by a single hand.

A cutting-off saw with a safety protection device, including a base; a support arm arranged on the base; a cutting blade coupled to the support arm by a driving head; a fan-shaped fixed guard and a movable guard configured to enclose the cutting blade and can be combined into a single disc; an extension arm coupled to a top portion of the support arm; the movable guard coupled to one end of a guard connecting rod; the other end of the guard connecting rod formed into an arc-shaped elbow and coupled to a stop button and the extension arm. An arc-shaped bayonet having a radian matching with that of the arc-shaped elbow of the guard connecting rod is arranged on a lower portion of the stop button. It ensures that the movable guard will never be turned upwards during the operation of loading or unloading a workpiece.
