摘要： In an angle-grinder with a rotating handle and a latch for fixing the handle in two different rotational positions, an interlock mechanism is provided for greater security against unwanted rotation of the handle when the tool is being used. The interlock mechanism is moved to a locking position by depressing the trigger to start the motor, and thus provides a safety lock backing up the latch, in case the latch is accidentally released during use. In its unlocking position the interlock mechanism may prevent actuation of the trigger when the handle is not properly aligned in one of its operating positions.
摘要翻译：在具有旋转手柄和用于将手柄固定在两个不同旋转位置的闩锁的角磨机中，提供互锁机构，用于在使用工具时更好地防止手柄不必要的旋转。通过按下触发器来启动电动机，互锁机构被移动到锁定位置，并且因此在使用期间意外释放闩锁的情况下提供了将闩锁备用的安全锁。在其解锁位置时，当手柄在其一个操作位置未正确对准时，互锁机构可以防止触发器的致动。
