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.
Claims9
An adjusting structure of a laser indicator of a sawing machine, which laser indicator is securely fitted on a rotating shaft of a sawing machine;
- said rotating shaft having a saw securely fitted thereto;
- said laser indicator comprising;
- a base, the base having two opposing fixed pieces fixed thereon;
- an upper cover, the upper cover and the base being coupled together in a separable manner;
- a circuit board secured on the base;
- a battery set;
- a laser module;
- the circuit board, the laser module, and the battery set being connected together to comprise a circuit;
- the base having a though hole for allowing a laser beam emitted from the laser module to pass through;
- the laser module having a pivotal post-shaped portion on each of two lateral sides thereof;
- the laser module being pivoted to the opposing fixed pieces on the base at the pivotal post-shaped portions thereof;
- a prism fitted on a laser emitting end of the laser module;
- an elastic member exerting elastic force on the laser module;
- and an adjusting element, the adjusting element being fitted to the upper cover and touching the laser module.
