And then, the main control mechanism transmits a second instruction for controlling the motor 2 of the driving mechanism to rotate to the motor 2 after delaying for a preset time period. The motor 2 drives the horizontal bevel gear assembly 4 which is moved upwards to horizontally rotate, and since the horizontal bevel gear assembly 4 is meshed with the vertical bevel gear 11 at the moment, the horizontal bevel gear assembly 4 which horizontally rotates drives the vertical bevel gear 11 to vertically rotate, so that the vertical rotating shaft 10 is driven to vertically rotate, and then the camera 12 is driven to vertically rotate; wherein the delay preset time period is two seconds.
As shown in fig. 7, when the command is a command for horizontally rotating the camera 12, the main control system 17 first sends a first command for controlling the lifting mechanism 18 to the lifting mechanism 18, the lifting mechanism 18 immediately executes the first command, and at this time, the first command is a command for commanding the lifting mechanism 18 to move down the shift fork 9, so as to drive the horizontal bevel gear assembly 4 to move down to be engaged with the housing 5. And then, the main control mechanism transmits a second instruction for controlling the motor 2 of the driving mechanism to rotate to the motor 2 after delaying for a preset time period. The motor 2 drives the horizontal bevel gear assembly 4 which moves downwards to horizontally rotate, and the horizontal bevel gear assembly 4 which horizontally rotates drives the shell 5 to horizontally rotate due to the fact that the horizontal bevel gear assembly 4 is clamped with the shell 5 at the moment, so that the camera 12 is driven to horizontally rotate; wherein the delay preset time period is two seconds.
The main control system 17 is arranged in the embodiment, so that the camera 12 can be automatically controlled to rotate horizontally and vertically.
