The adjusting cylinder 23 can drive the rotation of the internal structure through the air intake and exhaust. The angle of the rotating frame 30 is adjusted by the transmission shaft 24, so that the laser can be reflected at a specific angle, so that the first laser receiver 9 and the second laser receiver 13 receive the laser signal.
