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.

本斜切锯斜角锁定与定位系统包括与转盘相对固定的第一锁定单元，以及连接于斜切锯斜切臂的第二锁定单元。执行器可在第一位置与第二位置之间移动，以驱动第二锁定单元相对于第一锁定单元运动。当处于第一位置时，第二锁定单元的制动构件与第一锁定单元的弧形表面啮合，从而将锯切单元相对于转盘锁定。当处于第二位置时，制动构件脱离弧形表面，由此允许锯切单元进行枢转运动；此时第二锁定单元的定位构件可与第一锁定单元的定位孔啮合，以将锯切单元相对于转盘定位至预设斜切角度。
