Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a national phase application under 35 U.S.C. 371 of International Application No. PCT/CN2020/120748 filed on Oct. 14, 2020, the entire contents of which are incorporated herein by reference.

BACKGROUND In order to improve the shooting accuracy and adapt to different shooting occasions or targets, it is necessary to adjust the emission angle of the LED light source of the inner-red-dot aiming device. Generally, the adjusting screw and the return spring are configured to be matched with each other to complete the adjustment of the pitch angle or the left-and-right angle of the emission angle of the LED light source, and especially the up-and-down adjusting mechanism operates independently, inevitably causing the mutual influence, resulting in the adjustment of the pitch angle to be affected by the adjustment of the left-and-right angle, and thus leading to the low precision and instability and reducing the good user experience. For example, referring to Invention Patent No. 2016209805049, titled “LIGHT SOURCE ADJUSTING MECHANISM FOR INNER-RED-DOT AIMING DEVICE”, each of the adjustment of the pitch angle and the adjustment of the left-and-right angle depends on an independently operating mechanism. In addition, the existing inner-red-dot aiming devices mainly rely on rechargeable batteries for power supply, or combined with solar cells for supplementary power supply.
