摘要： A miter saw is provided having a support arm that is pivotally mounted to a base for adjustment of a pivot angle, the saw including a detent mechanism to provide pivot stops at common bevel angles, such as at 45° L, 0° (vertical), and 45° R. The detent mechanism includes a step-shaped, arcuate detent block mounted to the support arm in an adjustable manner to permit the accurate setting of the block in a home position. In an embodiment, a pair of set screws acts against opposite ends of the detent block, permitting precise adjustment in either direction. An axially movable detent pin is mounted to the base to contact against stepped surfaces of the block. The arm is free to pivot within a bevel angle range defined by one of the surfaces. Steps between surfaces act as a pivot stops, abutting the pin at a corresponding predetermined angle of the arm.
