The invention relates to the technical field of consultation services, and discloses a built-in device capable of adjusting the angle of a camera. The built-in device comprises a bracket, and the topof the bracket is rotatably connected with a vertical rotating frame. The left side surface of the vertical rotating frame is fixedly connected with a rotating frame guide wheel, and the right side ofthe bracket is provided with a rotating ball. The top of the rotating ball is fixedly connected with a protruding shaft, and the interior of the rotating ball is fixedly connected with the camera. According to the built-in device capable of adjusting the angle of the camera, the vertical rotating frame, the rotating frame guide wheel, the rotating ball, the protruding shaft, a U-shaped groove, ahorizontal rotating frame, a sliding block, a power wheel, a driven wheel, a limiting rod, a limiting wheel and a small guide wheel are matched for use, and therefore the effect of adjusting the angleof the camera in the horizontal direction and the vertical direction is achieved. The angle of the camera can be freely adjusted during consultation, a consultation target can be carefully observed more conveniently, and the automatic adjustment mode is quicker and more accurate.
