Laser alignment device of a circular saw
The present invention relates to a laser alignment device of a circular saw, including a rotary disk base, a protective cover, and a magnetic ring base. The rotary disk base is mounted on a drive shaft of a circular saw. The rotation shaft of the motor may rotate the drive shaft to rotate the rotary disk base, so that the rotary disk base may be rotated at a high speed, and the silicon steel plates and the armature coil of the rotary disk base may be rotated at a high speed. Thus, an induced current may be produced between the silicon steel plates and the armature coil of the rotary disk base and the stator member of the magnetic ring of the magnetic ring base, so as to provide an electrical energy to the laser generator.
