Abstract: A trimmer head for a trimmer has a base member having a trimmer line opening. A clamping device arranged in the base member clamps a trimmer line that defines a cutting plane when rotated. The clamping member of the clamping device is rotatably disposed on a pivot bolt having a pivot axis positioned in a plane that is parallel to the cutting plane. The clamping member is spring-loaded by a clamping spring into a clamping position. The trimmer line is secured in the clamping position between a clamping surface and the clamping member. A centrifugal force acting on the trimmer line loads the clamping member in the clamping position. A U-shaped bracket has bracket legs connected by a stay. The clamping member is positioned between the bracket legs. The pivot bolt is supported on the bracket leg ends. The stay of the U-shaped bracket forms the clamping surface.

Abstract: An internal combustion engine has a combustion chamber having a spark plug arranged thereat. A crankcase supports a crankshaft. An intake for introducing fuel and combustion air into the combustion chamber is provided. An exhaust for exhausting combustion gases from the combustion chamber is provided. A piston is connected to the crankshaft and drives the crankshaft in rotation. A wheel member is connected to the crankshaft and rotates with the crankshaft. An alternator driven by the crankshaft supplies electric power to a consumer. The alternator is arranged within a radial boundary of the wheel member and external to the crankcase. The alternator has a stator and a rotor, wherein the crankshaft penetrates the stator and wherein the rotor is fixedly connected to the wheel member.
