The direction adjusting motor is used for driving the hollow gear to rotate.

The center of the light-receiving surface of the area array light-receiving part fixed on the holder should coincide with the axis of the hollow gear 4d so that the light-receiving surface of the area array light-receiving part is disposed concentrically with the hollow gear 4 d.

The azimuth adjustment motor 4a is used to drive the hollow gear 4d to rotate. The hollow gear 4d is inserted into the insertion hole of the eccentric rotary arm 3d and can rotate therein, namely, the eccentric rotary arm 3d is provided with an insertion hole for inserting the hollow gear 4 d. When the eccentric shaft 3c drives the eccentric rotary arm 3d to rotate, the eccentric rotary arm 3d drives the hollow gear 4d to rotate around the axis of the eccentric shaft 3 c.
