<p>A hand-held motor-driven cutting device is provided, comprising a motor 2, a first cutting tool 3, and a first transmission 5 arranged to translate a rotating motion to a reciprocating motion of the first cutting tool 3. The first transmission comprises a first rotatable part 6 arranged to be driven by the motor 2 and a first connecting rod 9 with a first end 11 and a second end 12. The first end 11 is eccentrically connected to the first rotatable part 6 at a first connecting point 10 of the first rotatable part 6 and the second end 12 is connected to the first cutting tool 3. The first transmission 5 comprises a force limiting element 4 arranged between the first rotatable part 6 and the first cutting tool 3 in order to prevent a transmitted force applied to the first cutting tool 3 from exceeding a predetermined force level. The present invention also relates to a method of transmitting momentum in a hand-held motor-driven cutting device.</p> |
