ABSTRACT:
A portable trimmer for cutting weeds comprises a cutter, a driving device for rotationally driving the cutter, a control lever for controlling power of the driving device, a braking device for stopping rotation of the cutter, and an interlocking device operatively connected with the control lever and the braking device. The braking device has a wedge shaped brake shoe that is connected with the interlocking device and has an inclined upper surface inclined downwardly from a rotationally retarded side toward a rotationally advanced side of the cutter, a housing enclosing the brake shoe and having an inclined guide surface opposite to the inclined upper surface of the brake shoe, and a pressing device provided between the brake shoe and the housing and for causing an initial movement of the brake shoe toward a cutter surface of the cutter. The inclined guide surface guides the brake shoe from a braking position to a released position where the brake shoe is spaced from the cutter surface by being moved toward the rotationally retarded side of the cutter by being pulled by the interlocking device against a pressing force applied by the pressing device.
