[0006] Further, a chamfer is arranged at one end of the spherical lens connected with the through hole one, and the chamfer is a 60° chamfer.

[0007] Further, the depth of the through hole one is greater than a set value.

[0008] Further, the outer diameter of the mirror cover section is greater than that of the connecting section one, and the outer diameter of the mirror cover section is equal to the outer diameter of the threaded cylinder two.

[0009] Furthermore, the lens cover section is provided with a lens cover connecting thread.

[0010] Furthermore, the fixing component one includes a cylindrical threaded section, the threaded section is connected to a transition section, the diameter of the transition section is smaller than that of the threaded section; the end of the transition section is provided with an isolation wall two, the center of the isolation wall two is provided with a through hole two, the through hole two is coaxial with the threaded section, the diameter of the through hole two is smaller than that of the spherical lens, and the through hole two is connected to the spherical lens.

[0014] The beneficial effects of this scheme can be seen from the description above. It has a simple structure, reasonable design, and the following advantages:

[0015] (1) A spherical lens is used. The diameter of the spherical lens is small, and the diameter of the emitted parallel light is small, which helps the gun to be pointed and aimed. The depth of the through hole is greater than the set value, which can focus the light spot of the gun to be pointed and aimed within 2cm in diameter at a distance of 100m.

[0016] (2) The structure is simple, which makes the overall size of the equipment smaller and the weight lighter. For firearm accessories, it is easy to adjust and maintain and easy to carry.

[0017] (3) Through hole one and through hole two are chamfered so that the spherical surface of the spherical lens contacts the plane rather than the edge, thus avoiding scratches and pressure marks on the surface of the spherical lens. Since the incident light receiving part and the outgoing light emitting part cannot be determined when the spherical lens is installed, if there are scratches and pressure marks on the surface of the spherical lens, they are likely to be located at the incident light receiving part and the outgoing light emitting part after installation.

[0018] (4) Using a 60° chamfer can further reduce the radius of the spherical lens. Attached Figure Description
