摘要:
A trimmer head of a hand-held cutting device may include a spool onto which trimmer line is loadable and from which the trimmer line is dispensable, a housing including a first housing portion and a second housing portion operably coupled to the first housing portion to house the spool where the housing is driven rotationally about an axis by a shaft during powered operation of the device, a coupling assembly configured to selectively couple the spool to and decouple the spool from the housing during powered operation of the device based on an axial position of the coupling assembly within the housing, and a button operably coupled to the coupling assembly to alter the axial position of the coupling assembly when the button is moved out of a rest position by a bump of the button on a surface.
