Abstract (en)
The present invention relates to a safety mechanism for manual cutting machines comprising a cutting element (2) and a motor (3), comprising a throttle trigger (4) connected to the motor (3), configured to accelerate the motion of the cutting element (2); and a locking device (5) configured to lock the cutting element (2). Wherein the throttle trigger (4) has a first path (Ra) that starts from a rest position (Po) to a safety position (Ps), which enables the motion of the cutting element (2) to be accelerated when the throttle trigger (4) is pulled from the rest position (Po) to the safety position (Ps); and a second path (Rs) that occurs after the first path (Ra), which enables the locking device (5) to be activated in order to lock the cutting element (2) by continuing to pull the throttle trigger (4) once the safety position (Ps) has been exceeded.
