[0025] Benefits: The provision of the transparent protective plate 45 facilitates the operation of the lens 3, thereby enhancing the practicality of the device.

[0026] The working process of this utility model is as follows:

[0027] When the pan-tilt camera is in use, in order to ensure the quality of the lens 3, a protective component 4 is provided. When other objects are about to collide with the lens 3, the protective component 4 provided on the front of the lens 3 will work, and then the transparent protective plate 45 will replace the lens 3 to contact the object, and transfer the external force it receives to the first telescopic rod 42 and the buffer spring 43.

[0028] In the above scheme, when the pan-tilt camera is in use, in order to avoid the connection line 5 from getting entangled with other components, a wire harness auxiliary component 6 is provided. Before the pan-tilt camera body 2 is used, the second limit frame 67 inside the wire harness auxiliary component 6 is first pulled outward. After pulling a certain distance, one end of the connection line 5 is passed through the inside of the two sets of wire harness auxiliary components 6, and then the second limit frame 67 is slowly loosened. At this time, the reset spring 66 will restore the second limit frame 67 to its original position, so that the first wire harness wheel 64 and the second wire harness wheel 69 will limit the position of the passing connection line 5, thereby avoiding the connection line 5 from getting entangled with other components.
