摘要： A trimmer head configured to receive fixed-length segments of trimmer line has a main housing with a cylindrically shaped side wall forming an open end with diametrically opposed trimmer line holes formed therein. The main housing is rotatable about its central axis by means of a drive shaft. The trimmer head receives an insert body in its open end that is rotated by the main housing. The insert body has an arcuate channel extending from the first line hole adjacent one side of the insert body to the second line hole adjacent the diametrically opposed side of the insert body when the insert body is in a load/unload position with respect to the main housing. In this position, there is a substantially direct guide path between the first and second line holes that allows for easy movement of the line segment along the path. The insert body is rotatable and movable axially with respect to the main housing to an operational position. When in this position, the line segment is forced to take an indirect path between the first and second trimmer line holes, thereby securing the line segment in place during use of the trimmer head.

摘要： A combination blower assembly and string trimmer whereby the string trimmer head is easily detachable without the use of any tools. The device includes a blower assembly that further includes an upper and lower housing mated together to form a volute-shaped cavity where an impeller with airfoil-shaped blades reside. The detachable string trimmer head is located under the lower housing of the blower assembly and is easily attached or removed from the blower assembly by a simple push and turn motion. The blower assembly further includes an air inlet and air inlet cover. When the air inlet cover is rotated to a position where the air inlet is open the blower assembly is operable and the string trimmer is inoperable. Furthermore, when the air inlet cover is rotated to a position where the air inlet is closed the blower assembly is inoperable and the string trimmer is operable.

摘要翻译： 组合鼓风机组件和弦线修剪器，其中弦线修剪器头部可以容易地拆卸而不使用任何工具。 该装置包括鼓风机组件，该鼓风机组件还包括配合在一起的上部和下部壳体，以形成具有翼型叶片的叶轮所在的蜗壳形空腔。 可拆卸的弦线修剪器头位于鼓风机组件的下壳体下方，并且通过简单的推动和转动运动容易地附接或从鼓风机组件移除。 鼓风机组件还包括空气入口和空气入口盖。 当空气入口盖旋转到空气入口打开的位置时，鼓风机组件可操作，并且弦线修剪器不可操作。 此外，当进气口盖旋转到空气入口关闭的位置时，鼓风机组件是不可操作的，并且弦线修剪器可操作。
