Abstract
An optical marking mechanism for a power tool, the power tool comprising a cutting blade with a cutting width. The optical marking mechanism comprising a light source emitting a first light beam and an optical element located on the end of the emitting light for converting the first light beam into a planar light beam. The planar light beam being able to assist a user in incorporating the cutting width of the cutting blade when cutting a workpiece to increase the measurement accuracy of the resultant cut workpiece.

An optical marking mechanism for a power tool, the power tool comprising a cutting blade with a cutting width, the optical marking mechanism comprising:
- a light source emitting a first light beam;
- an optical element for converting the first light beam into a planar light beam, the optical element being located on an emitting end of the light source;
- and
- a light blocking means located in a light path of the light source and the optical element.
An optical marking mechanism for a power tool, the power tool comprising a cutting blade with a cutting width, the optical marking mechanism comprising:
- a light source emitting a first light beam;
- an optical element for converting the first light beam into a planar light beam, the optical element being located on the emitting end of the light source;
- wherein the optical element is a lens, the lens having a first part which allows light to pass through without diverging.
A method for marking lines using an optical marking mechanism for a power tool, comprising:
- providing a light blocking means on a light path of a light source and an optical element, which creates a laser module project two parallel planar laser beams;
- projecting the two parallel laser beams on a workpiece to form two parallel laser indicating lines, each laser indicating line having two sides, a distance being formed between the two sides that are adjacent to each other.
