Therefore, another "permanent parallel" adjustment mode is mostly used: the light path of the sighting telescope and the light path of the laser are in a relatively parallel state, and the target can be hit after a certain distance is reached by the diffusion of the laser;
In the second calibration process by adjusting the relative parallelism of the two light paths, a distance measuring device is needed, the traditional distance measuring device mostly measures the relative distance between the two light paths through a tape measure, then the measured value is marked on the reflective cloth in a mode of two endpoints, after entering a gun calibration mode, the cross center of the sighting device is aligned with an upper point, the light spot center is aligned with a lower point, and then the calibration is completed if the two light paths are all at the same point after the distance is replaced for multiple tests;
however, the distance measurement mode occurs in the actual use process, because the two end points of the measuring tape cannot be exactly positioned at the central axes of the sighting telescope and the laser transmitter due to manual measurement, and because the measuring tape is provided with a thicker shell, errors in measurement are further larger, so that the situation that the correction precision is low and multiple times of correction and verification are needed is easily caused;
therefore, we improve on this and propose a distance measuring device for calibrating a laser countermeasure sighting telescope.

a calibrating plate 44 is arranged on the inner side of the extension arm 43 and is used for being spliced with the end part of the telescopic rod 41, and an anti-slip rubber sleeve 45 is wrapped on the surface of the clamping head 42;
The calibration plate 44 is located on the central axis of the ring body 31, so that when the ring body 31 is respectively located on the corresponding sighting telescope or gun barrel, the measurement distance between the two opposite sides is synchronously reflected through the calibration plate 44, and meanwhile, through the arrangement of the telescopic rod 41, the two positioning units 3 can be reasonably adjusted according to the positions corresponding to the sighting telescope or gun barrel, so that the requirements of clamping assembly can be met;
Through the arrangement of the anti-skid rubber sleeve 45, when the clamping head 42 is sleeved on the indication seat 21, the elastic action of the supporting spring 23 and the reset spring 28 can be overcome, and the clamping of the clamping head 42 position in the corresponding indication seat 21 can be ensured;
The indicating unit 2 comprises an indicating seat 21 sleeved on the surface of the measuring unit 1 in a sliding manner, a bearing seat 22 arranged in the indicating seat 21 in a sliding manner and a supporting spring 23 connected to one side of the bearing seat 22 and fixed with the side wall of the indicating seat 21;
