When moving to one side, the tension of the other winding roller 601 is tightened, so that the camera 501 can be reset when the head is reset. A connecting rope 602 is arranged on the outside of the winding roller 601, and the two ends of the connecting rope 602 are respectively connected to the slider 402 and the inner plate 2, so that they are linked. When one side of the inner plate 2 rotates toward the inside of the helmet 1, the connecting rope 602 is pulled, and the slider 402 is driven by the connecting rope 602 to slide in the same direction in the slide groove 401, and the camera 501 is driven to move with the rotation of the head.

[0023] In this embodiment, all electrical components are controlled by conventional controllers.

[0024] For example, please refer to Figure 1-5The inner plate 2 is located in the helmet 1 and is rotatably connected to the inner wall of the helmet 1 through a bearing. The two mounting frames 3 are rotatably connected to the outer wall of the helmet 1 through a damping shaft. The angle of the monitoring device can be changed by rotating the mounting frame 3. The annular frame 4 is connected to the outer wall of the mounting frame 3 through bolts. The end of the annular frame 4 away from the mounting frame 3 is an arc structure. The slide groove 401 is located at the arc structure. The slider 402 is located in the slide groove 401 and is slidably connected to the inner wall of the slide groove 401 through a slide rail.
