A coding handle 801 is sleeved on the outer sides of the encoder base 808 and the coding handle connecting ring 810. The top of the coding handle 801 is fixed to the encoder button retaining ring 803 (threaded connection and adhesive application), and presses down and fixes the encoder button cover 802. Three threaded holes are evenly distributed along the circumferential direction on the bottom side of the coding handle 801.

[0093] 6) The pressing and rotating operations of the encoder are independent of each other, reducing mutual interference, maintaining a good hand feel, and effectively improving ergonomics.

[0094] 7) It adopts an unconventional internal layout. The power supply group is vertically set in the middle of the scope body. There are protruding handwheels on the top, left and right. The focusing handwheel and TYPE-C interface are set in the same mechanism, which effectively saves space. The sight adopts a conch-shaped shape, with a small size, light weight, coordinated appearance, and beautiful and smooth contours.

[0095] 8) The utility model has a peripheral interface, and the interface structure can be adjusted according to different devices to effectively meet actual combat needs.

[0096] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
