摘要： A circular saw includes a base plate defining a base plane, a bevel bracket which supports a circular saw blade and is pivotally mounted on the base plate for tilting the blade, the bevel bracket having a pivoting axis which is parallel to the base plane and the blade and perpendicular to a rotational axis of the blade, and the blade partly extending through an opening forming in the base plate, and an anti-splinter device for preventing cutting chips from splintering. The anti-splinter device comprises a pair of slides mounted in the opening and forming a gap between their opposing ends, an outcoming section of the blade passing through the gap, and slide driving means associated with the bevel bracket and driving the slides to move in conformity with the tilting of the blade to allow the gap to accommodate the positional change of the outcoming section of the blade.

摘要： A portable power tool includes a motor housing and a motor mounted in the motor housing. The motor includes a rotary spindle. The portable power tool also includes a trigger configured to be actuated and released to switch on and off the motor. The portable power tool also includes a mechanical brake assembly connected with the trigger and automatically operated by the trigger. Accordingly, the brake assembly releases the spindle when the trigger is activated and brakes the spindle when the trigger is released.
摘要翻译： 便携式电动工具包括马达壳体和安装在马达壳体中的马达。 电机包括旋转主轴。 便携式电动工具还包括触发器，其构造成被致动和释放以接通和断开电动机。 便携式电动工具还包括与触发器连接并由触发器自动操作的机械制动组件。 因此，当触发器被激活时，制动器组件释放主轴并且当触发器被释放时制动主轴。
