<p>The laser marking electric cutting tool in the field of electric tools comprises a base (1) for disposing the work piece to be cut, a support (2) fixed to the base (1), a saw cutting member (4) hinged on the support 2 and a laser emitter (3-1). It is characterized in that said laser emitter (3-1) is arranged in the hinge shaft (3) of the support (2), and a light hole is provided on the hinge shaft (3) for enabling the laser beam to reach the surface of the work piece just under the saw cutting member. Obviously, because of the built-in laser emitter, it is possible not only to keep the former configuration and compact structure of the entire machine, but also to protect the emitter by the outer cylindrical surface of the hinge shaft from contamination or damage.</p> |
