Abstract
A handheld power tool has a monostable operating button 6 which has a stable switching position and a pressed switching position. A catch 32 which can be pivoted between a releasing position and a locking position in a pivoting direction 34 is provided, wherein the catch 32, in the locking position, stops the monostable operating button 6 in the pressed switching position. An operating knob 30 can be moved by the user in a shifting direction 31 which is perpendicular to the pivoting direction 34. The catch 32 is attached to the operating knob 30 by means of a joint 36. A slotted link 38 converts a movement of the catch 32 along the shifting direction 31 into a pivoting movement in the pivoting direction 34.
Claims18
A handheld power tool comprising:
- a tool holder for holding a tool;
- a percussion mechanism;
- an electric motor for driving the percussion mechanism;
- a monostable operating button having a stable switching position and a pressed switching position;
- a device controller switching off the electric motor in response to the stable switching position and activating the electric motor in response to the pressed switching position;
- a catch pivotable between a releasing position and a locking position in a pivoting direction, the catch, in the locking position, stopping the monostable operating button in the pressed switching position;
- an operating knob movable by the user in a shifting direction perpendicular to the pivoting direction;
- a joint, the catch attachable to the operating knob via the joint, the joint fastening the catch to the operating knob in both the releasing and the locking position;
- and
- a link converting a movement of the catch along the shifting direction into a pivoting movement in the pivoting direction.
