A motorized vegetation trimmer apparatus (10) comprising an elongate main handle (12) to which is connected a motor (14) that rotatably drives a trimmer head (16) located at a distal end of the handle. The trimmer head (16) carries one or radially outwardly projecting cutting members (18) which cut vegetation as the trimmer head rotates. Each cutting member comprises a finite length of flexible strand. The cutting member is releasably gripped by a one-way gripping mechanism including a reciprocating gripping member (25, 152, 252) and a compression spring )50, 150, 250) that biases the gripping member into gripping contact with the strand.
L'invention concerne un appareil motorisé (10) servant à tailler la végétation, comprenant une poignée principale allongée (12) à laquelle est connectée un moteur (14) entraînant de manière rotative une tête tranchante (16) située à une extrémité distale de la poignée. La tête tranchante (16) comprend un ou plusieurs éléments tranchants (18) saillant de manière radiale vers l'extérieur, coupant la végétation tandis que la tête tranchante effectue un mouvement de rotation. Chaque élément tranchant comprend une longueur de filament flexible définie. L'élément tranchant est bloqué de manière amovible par un mécanisme de préhension unidirectionnel pourvu d'un élément (25, 152, 252) de préhension à mouvement alternatif et d'un ressort (50, 150, 250) de compression polarisant l'élément de préhension en contact avec le filament.
