An adjusting seat 9 is installed on the magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8. Four arc grooves are arranged below the adjusting seat 9. The first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8 slide in the grooves below the adjusting seat 9. When the adjusting seat 9 is in a horizontal position, the counterweight iron inside the adjusting seat 9 is located directly above the first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8, and is used to connect the first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8. The suction seat 7, the fourth magnetic seat 8, and the adjustment seat 9 are connected with the first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8 by magnetism. The adjusting seat 9 is fixedly mounted with a steering seat 10, and the steering seat 10 is fixedly mounted with an infrared transmitter 11. The protective box 2 is fixedly mounted with a reflector 27 and a light-sensitive screen 28.

The reflector 27 can reflect the light of the infrared transmitter 11. The fine-tuning pointing device is arranged above the vehicle for automatic navigation guidance of the vehicle. When the infrared transmitter 11 is started to generate infrared light, when it irradiates the reflector 27, it is reflected by the reflector 27 to the light-sensitive screen 28 for reception. The light-sensitive screen 28 determines the angle of deviation between the plane where the adjustment seat 9 is located and the plane of the protective box 2 according to the sensed light signal, thereby determining the direction deviation. The reflection of the reflector 27 can increase the optical path, and the enlarged angle is convenient for the light-sensitive screen 28 to sense the signal. According to the current moving direction of the vehicle, the angle of the adjustment seat 9 needs to be automatically changed. Rotating the first gear rod 12, the second gear rod 13, the third gear rod 14, and the fourth gear rod 15 can drive the first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8 to rotate.
