Title: Led light laser sighting device

Description:
FIELD OF THE INVENTION 
     This invention relates to a laser sighting device, and in particularly to such a laser sighting device with an LED (Light Emitting Diode) light as can be rapidly mounted. 
     BACKGROUND OF THE INVENTION 
     Sighting device is an important part of small arms. In the development of small arms, there have successively appeared various types of laser sighting devices, such as mechanical laser sighting device, optical laser sighting device and laser sighting device. Laser indicator sighting device finds wide use in fire arms, and especially it has unique advantages when it is used as short-distance rapid fire sight. On the other hand, LED, owing to its technology development, and especially owing to the sophistication of the production of the high power cold white LED, now features low energy-consumption and high brightness and thus instantly finds use in the arms for illumination at night. 
     In the development of such sighting devices of the arms, there is a trend towards making a combined sight by combining an LED light with an laser indicator. Nevertheless, such a combined sight of the prior art has three disadvantages. First, it has an incompact structure without an integral design, because the LED flashlight and the laser indicator are separate, i.e., being mounted on the arms separately from each other, or the laser indicator is attached to the LED flashlight. Second, it has a large volume and weight, rendering the arms including excessive accessories, requiring complex operation and presenting inconvenience in carrying. Third, it requires lengthy installation, which involves mounting it on a guide, usually by conventional screw-clamping with accessory tools, for example a wrench, thus necessitating provision of tools at all times and presenting inconvenience in practical use.
