the driving mechanism further comprises a force transmission piece, the force transmission piece is matched with the guide rod in a sliding mode, an elastic piece is arranged between the force transmission piece and the guide rod, and the elastic piece is used for enabling the force transmission piece to have a movement trend close to the pushing piece; the oblique photographing module is connected with the force transmission piece; the pushing piece can push the force transmission piece to slide relative to the guide rod when sliding relative to the machine shell, so that the oblique photographing module extends out of the opening.
8. The oblique photogrammetric surveying device of claim 7, characterized in that:
the door body comprises a first door plate and a second door plate, the first door plate is rotatably connected with the shell, the second door plate is rotatably connected with the first door plate, and the inhaul cable is connected with the second door plate; when the door body is located at a position for closing the opening, a distance is reserved between the pushing piece and the force transmission piece, the driver drives the pushing piece to move close to the force transmission piece so that the oblique photographing module extends out of the opening, the pushing piece has a first stroke and a second stroke, and when the pushing piece moves in the first stroke, the pushing piece only drives the second door panel and the first door panel to rotate towards a direction for opening the opening; when the pushing piece moves in the second stroke, the pushing piece drives the second door panel and the first door panel to rotate towards the direction of opening the opening, and meanwhile, the force transmission piece enables the oblique photographing module to slide towards the direction of extending out of the opening.
9. The oblique photogrammetric surveying device of claim 7, characterized in that:
the elastic component is clamped between the force transmission component and the limiting component.
10. A oblique photogrammetric surveying device according to claim 9, characterized in that:
the limiting piece is in threaded connection with the guide rod.
