Referring also to fig. 4, probe assembly 43 includes a cartridge 431 and a flange 433 fixedly attached to cartridge 431. In the illustrated embodiment, cartridge 431 has a plurality of first fixing holes 432, such as screw holes, formed at its side ends. Correspondingly, the flange 433 is formed with a plurality of second fixing holes 434, and the second fixing holes 434 axially penetrate the flange 433.

In assembly, as shown in fig. 5, first, the adjusting seat 473 is fitted into the mounting block 419 of the lens barrel 411; thereafter, the probe assembly 43 is mounted to the mount 413 of the lens barrel 411 until the flange 433 abuts against the bottom of the mount 413. At this time, the lugs 435 of the flange 433 are opposed to the adjustment seats 473 one by one, and the first active surface 436 of the lug 435 is superposed on the radially inner side of the first sheet 475 of the adjustment seat 473, and the second active surface 437 is superposed on the axially inner side of the second sheet 477. While the first active surface 436 of the ear 435 and the first sheet 475 of the adjustment seat 473 are both planar in this embodiment, it should be understood that in other embodiments, both may be provided as curved surfaces.

The assembled gun sight 40 is then inspected and calibrated at the optical platform. As shown in fig. 6, when the axis of the movement 431 of the probe assembly 43 and the axis of the lens assembly 41 cannot completely coincide, the center a of the movement image deviates from the target center B. At this time, the position of the probe assembly 43 is adjusted by rotating the adjusting screw 471 until the axis of the movement 431 coincides with the axis of the lens assembly 41, thereby completing the calibration of the gun sight 40. The gun sight 40 corrected by the adjusting screw 471 can ensure that the imaging center a of the movement of the gun does not deviate from the target center B without further correction after being assembled with the gun, as shown in fig. 7, and the shooting accuracy is ensured. According to the gun sight disclosed by the utility model, through the arrangement of the adjusting screw 471, the position of the detector assembly 43 can be conveniently and finely adjusted in a radial plane after the assembly, the influence of the tolerance of the component or the deviation in the assembly process on the gun sight 40 is compensated, the coaxiality of the detector assembly 43 and the lens assembly 41 is ensured, the integral structure is simple, the operation is convenient, the adjusting effect is good, and the user experience is good.
