[0034] In addition, the shooting intelligent controller is installed in the vertical rod 5, and the shooting intelligent controller is provided with an instruction module, a processing module and a shooting positioning module. The instruction module is electrically connected with the processing module, the control button 8 and the touch display screen respectively.

The end of the mirror 11 away from the camera module 2 is rotationally connected with a connecting plate 20 through a rotating shaft. The side of the storage groove 13 close to the camera module 2 is provided with an arc-shaped groove matched with the rotating shaft. When the rotating shaft on the mirror 11 moves to the arc-shaped groove along the storage groove 13, the rotating shaft on the mirror 11 slides along the arc-shaped groove. The end of the connecting plate 20 away from the mirror 11 is rotationally connected with a push plate 21. The push plate 21 is controlled to reciprocate along the storage groove 13 through the driving mechanism, so that the mirror 11 is controlled to reciprocate along the storage groove 13, the mirror 11 is controlled to stretch out or retract, and the push plate 21 pushes the connecting plate 20 and the mirror 11 to move forward and stretch out, as shown in Figure 6As shown, when the rotating shaft moves to the arc-shaped groove on the reflector 11, the rotating shaft will slide along the arc-shaped groove, so that the reflector 11 deflects, as shown in the figure.

The driving motor 23 and the electromagnet 26 are electrically connected with the processing module. When it is necessary to control the corresponding reflector 11 to extend and deflect by a specified angle, the instruction module sends a control signal to the processing module, and the processing module controls the driving motor 23 to work by controlling the driving motor 23 to work, so that the screw rod 22 is driven to rotate, thereby controlling the movement of the screw rod sleeve 24 and the driving rod 25. At the same time, the processing module controls the electromagnet 26 on the driving rod 25 corresponding to the reflector 11 to work, and the electromagnet 26 generates magnetism and magnetically attracts the push plate 21. Therefore, the corresponding push plate 21 is moved during the movement of the driving rod 25, thereby pushing the reflector 11 to extend, and the length of the reflector 11 extending and the deflection angle are controlled by controlling the movement distance of the driving rod 25.

[0037] Moreover, a distance sensor 27 corresponding to the driving rod 25 is mounted on the shooting head 1, and the distance sensor 27 is electrically connected with the processing module. The position of the driving rod 25 is detected by the distance sensor 27, and the detected distance data is sent to the processing module.
