Power tool

A power tool, which performs a predetermined operation by using a tool bit, comprising:

• at least one grip part,
• a dust suction device,
• wherein the dust suction device has a dust suction part that sucks and collects dust generated during operation at a tip of the tool bit, and the dust suction part can be moved between a first position in which the dust suction part covers at least a bit tip of the tool bit and a second position in which the bit tip is exposed to an outside environment prior to the operation, and is biased so as to be normally placed in the first position, and
• an operation mode switching mechanism that is capable of switching between a first operation mode in which the dust suction part placed in the first position is allowed to move between the first and second positions and a second operation mode in which the dust suction part moved from the first position to the second position is locked in the second position,
• wherein the operation mode switching mechanism is provided in a region of the grip part or its vicinity such that the operation mode switching mechanism can be operated with a user's hand holding the grip part,
• the operation mode switching mechanism comprises an operating part and a wire rope that transmits movement of the operating part to the dust suction part,
• the operating part is configured to move between i) a first operation position in which the dust suction part is allowed to move between the first position and the second position and ii) a second operation position in which the dust suction part is moved from the first position to the second position and is locked in the second position, and the first operation mode is selected when the operating part is placed in the first operation position, while the second operation mode is selected when the operating part is placed in the second operation position, and
• when the operating part is moved from the first operating position to the second operating position, the wire rope is moved by the movement of the operation part, and thereby the dust suction part is moved from the first position to the second position by movement of the wire rope.
