An improved structure of a laser indicator includes an outer tube, a cover cap, a focus adjusting device, an optical lens, and a circuit board having a laser diode disposed thereon. The outer tube and the cover cap are joined to form a rod-shaped indicator housing. The optical lens and the laser diode are provided inside the focus adjusting device, which is comprised of an inner cover and an outer cover working in conjunction with a metallic spring. The laser diode is fittingly disposed inside the inner cover, while the outer cover is screwably connected to the outer cover. The spring is disposed between the inner cover and the optical lens. One end of the outer cover is screwably coupled to the cover cap, while the other end thereof forms a smooth holding surface to facilitate turning of the outer cover in focus adjustment. The arrangement of the spring ensures the positioning of the optical lens and forms a bridge for the conduction of electric currents between the outer and inner covers, thereby avoiding the problem that the inner cover is isolated from the outer tube after it is coated with a fixing glue.

Structure of a laser indicator

The principle of the present invention is to turn an electric power to a mechanical power and to make use of a mechanical mechanism to control the action of stapling and the opening of position switch with the arrangement of a thermo breaker and a LED to detect power source and to give alarm signal at time of shortage of power.
