A power tool for cutting or trimming is provided. The power tool comprises a main body (110,210,310,410) having at least one handle (123,130,230) arranged to be grasp by a user during the operation of the power tool, an anti-vibration mechanism (100,150) arranged to reduce the transmission of any vibration forces generated by the main body to the at least one handle during the operation of the power tool, a locking mechanism (200) arranged to selectively restrict a rotational movement of the handle with respect to the main body and/or the power tool from being activated in response to an actuation of an actuator, a noise reduction engine air-intake mechanism (300) and a forward pointing exhaust outlet (400) arranged to discharge exhaust generated by a combustion engine (440). The power tool is improved and provides easy, practical and secure presentation and good user experience.
摘要:
The invention regards a system and method for assisting reductive shaping of an object into a desired 3D-shape by removing material. The system comprises a tool and a localization means. The tool is configured to remove material from an object by means of a cutting function or a grinding function performed by a working head of the tool. The localization means determines a position of the working head relative to the desired 3D-shape. Each time the grinding function or cutting function would remove material from an inside of the desired 3D-shape the cutting or grinding function is deactivated.
