Abstract

A trimmer head (1) arranged to be driven to rotate a trimming line (3), wherein the trimmer head comprises a housing (1a, 1b) and an inner body connected to a spool (13, 39) of the trimming line (1c), the trimmer head is characterized in that the inner body is arranged to be movable relative to the housing so that the trimming wire wrapped around the spool of trimming wire is released and drawn out by the centrifugal force caused by the rotation of the trimmer head, This allows the supply of trimming lines. According to a trimmer (10) comprising a trimmer head as described above, wherein the trimmer further comprises drive means (2, 4) for driving the trimmer head in rotation, and wherein the trimmer is arranged to The rotational speed of causes relative motion of the inner body relative to the housing.

Description

technical field [0001] The present application relates to a method for feeding a trimmer with trimmer line, a trimmer head and a trimmer, and in particular to automatic feeding of trimmer line for an electric trimmer. Background technique [0002] Electric trimmers operate by turning or spinning a line or lines at high speed. When the thread touches grass or other vegetation, the grass is mowed by the thread. This physical interaction between the grass and the trimming line causes the trimming line to wear down and the line often shortens over time. In order to provide a uniform cutting operation, more wire needs to be fed. [0003] The prior art solution is to provide the trimmer with a button which is arranged on the underside of the trimmer head. When the operator wants to feed more thread, he can do so by gently pushing the trimmer head onto the ground, thereby pushing the button that enables the supply of thread. [0004] Such solutions are shown, for example, in US...
