Abstract

A trimming tool (70) may have a variety of features such as a lockable telescoping tube (10), a tool guard (96) having a snap-fit fastener, an adjustment mechanism comprising a rotational mechanism (112) and a pivoting mechanism (114), or any combination of these features. A method of attaching a tool guard to a trimming tool is also provided.

Description

technical field [0001] The invention relates to a string trimmer. More specifically, the present invention relates to string trimmers having one or more different devices. Background technique [0002] String trimmers (sometimes commonly referred to as "weed wackers") are used to trim and sometimes edge lawns, light leaves and their respective borders. String trimmers typically employ a flexible nylon (or other plastic) cutting wire attached to a rotating head that spins at high speeds to cut vegetation. Such string trimmers may include electric or air motors that directly or indirectly power the rotating head. [0003] More recently, additional features have been included in such string trimmers, such as replaceable heads, self-feeding heads, telescoping handles, pivoting heads, and more. Current telescoping heads require turning screws, wing nuts, or other types of screw-type devices that hold the rod formed of concentric tubes in place by the friction created by the sc...
