[0028] like Figure 4-6A fixing device, comprising an assembly structure fixed threaded rod 8, a rotating inner ring 10 and a rotating outer ring 11, wherein the rotating inner ring 10 and the rotating outer ring 11 are connected by two inner ring rotating locking screws 9, and the line between the two inner ring rotating locking screws 9 passes through the center of the rotating inner ring 10, the assembly structure fixed threaded rod 8 passes through the sensor assembly structure upper cover 2, and the two ends of the assembly structure fixed threaded rod 8 are fixed on the inner wall of the rotating inner ring 10; the line between the two inner ring rotating locking screws 9 is perpendicular to the assembly structure fixed threaded rod 8; and also includes an integral fixed outer frame 14, wherein the outer ring is fixed to the integral fixed outer frame 14 by two connecting fastening bolts 12, and the line between the two connecting fastening bolts 12 is perpendicular to the line between the two inner ring rotating locking screws 9; the integral fixed outer frame 14 is respectively installed with a strong magnet 13 and a strong magnet 2 15 at the two connecting fastening bolts 12, and a strong magnet 3 16 is installed at the bottom of the integral fixed outer frame 14.

[0029] like Figure 7 ; The assembly fixture is attached to the iron frame of the sightseeing car through its own strong magnets;
