Adjusting structure of a laser indicator of a sawing machine

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 includes a base, a circuit board, a laser module connected to the circuit board, a vibrating switch, an elastic piece, a battery set, a covering member over the base, and threaded element; the elastic piece is secured to the base at one end while the laser module is fitted on the elastic piece; the covering member has a screw hole, and a through hole facing the laser module for allowing a laser beam to pass through; the threaded element is passed through the screw hole of the covering member and pressed against the elastic piece; thus, the orientation of the laser module can be adjusted for the laser beam to head towards the same direction as the saw blade by means of turning the threaded element.

1 . An adjusting structure of a laser indicator of a sawing machine,
 a laser indicator being securely fitted on a rotating shaft of a sawing machine, on which rotating shaft a saw is fitted;   the laser indicator comprising:   a base;   a circuit board secured on the base;   a laser module connected to the circuit board;   an elastic piece, the elastic piece being secured to the base at one end thereof; the laser module being fitted on the elastic piece;   a vibrating switch fitted on the circuit board;   a battery set, the battery set touching the circuit board such that the battery set, the laser module, and the vibrating switch together comprise a circuit;   a covering member positioned over the base, the covering member having a first through hole facing the laser module for allowing a laser beam emitted from the laser module to pass through; the covering member having a screw hole thereon; and   a threaded element, the threaded element being passed through the screw hole of the covering member and pressed against the elastic piece for changing position of the laser module.   
   
   
       2 . The adjusting structure of a laser indicator of a sawing machine as recited in  claim 1  further having a manual switch fitted on the circuit board; the covering member having a second through hole facing the manual switch. 
   
   
       3 . The adjusting structure of a laser indicator of a sawing machine as recited in  claim 1 , wherein the covering member includes front and rear covering parts; the front and the rear covering parts having a plurality of fasteners and fastening holes thereon; the front and the rear covering parts being coupled together with the fasteners being fitted in the fastening holes thereof.
