[0036] After adjusting the lens group of the parallel light source assembly 10, remove the well-tested and performance-good laser rangefinder 8 and avalanche tube, and then batch-detect the untested laser rangefinders 8. Turn on the laser rangefinder 8 and observe whether the light emitted by the laser rangefinder 8 hits the parallel light source assembly 10. This step is mainly used to detect whether the center point of the light source emitted by the optical path laser is parallel to the center point of the avalanche tube within a specified distance.

During the pushing process, the plug-in board 94 moves, and then the spring 95 is compressed.
