摘要: The present invention provides an ergonomical handle for a power tool that reduces the risk of injury to operator's wrist or forearm by redirecting torsional forces upper arm and reducing force provided operator necessary resist torque produced tool. includes concave channel means attaching adjacent barrel tool, such as annular collar with substantially elliptical outer diameter. In preferred embodiment, inner side wall are curved in nonparallel fashion so mirror planar dorsal sides hand. use, inserts hand into channel. walls frictionally engage may operate without gripping thereof.
