電動工具
Document Type and Number:
Japanese Patent JP4933707
Kind Code:
B2
Abstract:
An electric power tool has a motor-driven circular tool that can be clamped by means of a clamping device. A mechanical braking device (2) serves to brake the tool. A safety element (4) prevents improper handling of the electric power tool. In a safety position, the safety element (4) prevents the motor from being turned on and activates the braking device (2). In a release position, the safety element (4) allows the motor to be turned on and the braking device (12) is released. An additional locking mechanism prevents that a clamping lever, needed to actuate the clamping device, can be actuated in the clamped state in the safety position. In the release position of the safety element, the locking mechanism is unlocked.
