[0057] A laser rangefinder 6 is installed inside the housing 2 and located near the high-energy laser 5. The emitting end of the laser rangefinder 6 extends out of the housing 2, and the laser emitted by the emitting end of the laser rangefinder 6 is aligned with the height direction. It is used to measure the distance between its emitting end and a predetermined position on the bracket. Specifically, the kit has a mounting clip 16 with a detection surface that is perpendicular to both the laser emitted by the high-energy laser 5 and the laser emitted by the laser rangefinder 6.
