摘要：
Wire cutting head for a brush cutter. The invention relates to a wire cutting head (1) for a brushcutter with an elongated cutting wire (5) held tightly on a base body (2) of the wire cutting head (1) which protrudes outward through an opening of the wire (3) into the base body (2) and with the rotating wire cutting head (1) defining a cutting plane (12). a clamping device (8) is disposed on the base body (2) of the wire cutting head (1) for the cutting wire (5) which comprises a clamping body (10) movable about a pivot pin (16), wherein the pivot axis (26) of the pivot pin (16) is situated in a plane (13) approximately parallel to the cutting plane (12). the clamping body (10) is spring-loaded through a clamping spring (25) to a clamping position in which the cutting wire (5) is held between a clamping surface (28) and the clamping body (10). the clamping surface (28) and the swivel pin bearing (16) are made of a common component. In order to obtain a robust clamping device, to be easily assembled it is envisaged to make the component (17) as a U-shaped arch (19), and to arrange the clamping body (10) between the tabs (21, 22) of the bow (19). the pivot pin (16) of the clamping body (10) is supported at the ends of the arch flap (19), with the U-shaped arch (19) connecting the flaps (21, 22) to the web (20) ), the clamping surface (28) is made for the cutting wire.cabeça de corte de fio para uma roçadeira. a invenção refere-se a uma cabeça de corte de fio (1) para uma roçadeira, com um fio de corte (5) alongado, mantido apertado em um corpo de base (2) da cabeça de corte de fio (1), que se projeta para fora através de uma abertura do fio (3) no corpo de base (2) e com a cabeça de corte de fio (1) girando define um plano de corte (12). um dispositivo de aperto (8) está disposto no corpo de base (2) da cabeça de corte de fio (1), para o fio de corte (5), o qual compreende um corpo de aperto (10) móvel em torno de um pino giratório (16), sendo que, o eixo de giro (26)
