Miter saw

A bevel angle lock and detent system for a miter saw includes a first locking unit fixed relative to the turntable and a second locking unit coupled to a bevel arm of the miter saw. An actuator is moveable between a first position and a second position to move the second locking unit relative to the first locking unit. In the first position， a brake member of the second locking unit is engaged with an arcuate surface of the first locking unit to lock a saw unit relative to a turntable. In the second position， the brake member is disengaged from the arcuate surface， thereby permitting pivoting movement of the saw unit， and a detent member of the second locking unit is engageable a detent aperture of the first locking unit to locate the saw unit relative to the turntable at one predetermined bevel angle.

斜切锯用斜面角度锁定与定位系统包含与转盘相对固定的第一锁定单元，以及与斜切锯斜置臂相连的第二锁定单元。执行器可在第一位置与第二位置之间移动，以带动第二锁定单元相对第一锁定单元运动。当执行器处于第一位置时，第二锁定单元的制动件与第一锁定单元的弧形工作面啮合，从而将锯切单元相对于转盘锁定。当执行器处于第二位置时，制动件脱离弧形工作面，允许锯切单元进行枢转运动；与此同时，第二锁定单元的定位件可与第一锁定单元的定位孔啮合，将锯切单元相对于转盘定位至预设斜面角度。
