ABSTRACT:
A laser indicator is secured on a rotating shaft of a sawing machine, on which rotating shaft a saw is fitted; the laser indicator consists of a base, an upper cover, a laser module, and a threaded adjusting element passed through a screw hole of the upper cover; the laser module is pivoted to the base, and subjected to elastic force of an elastic member; the adjusting element is pressed against the laser module such that orientation of the laser module can be adjusted by means of turning the adjusting element; therefore, if the laser beam emitted from the laser module fails to head towards exactly the same direction as the blade of the saw, the user is allowed to turn the adjusting element to adjust the laser module to a correct position.
