In one embodiment, the walking driving motor is a stepping motor, and the first vehicle body 11 can be controlled to move in a certain step, so as to drive the fine adjustment device to move in a certain step, for example, the moving step of the first vehicle body 11 can be set according to the distance between two adjacent fine adjustment points, or according to the distance between the elevation adjustment screws, or according to the distance between the rail adjustment screws, so that the elevation fine adjustment arm 122/the rail fine adjustment arm 132 can be prevented from frequently performing attitude adjustment, and thus the track panel adjustment efficiency and the adjustment accuracy can be improved.

(2) In one embodiment, as shown in fig. 1 to 4, the fine adjustment device includes an elevation fine adjustment module, which includes two sets of elevation fine adjustment mechanisms 12 respectively disposed on the left and right sides of the first vehicle body 11.
