During the rotation process, the protective cover 2 is rotated by sliding the sliding groove 7 and the limit ring 4. A buffer assembly 11 is connected to one side of the instrument panel 1. The buffer assembly 11 includes a mounting plate 109 mounted on the outside of the instrument panel 1. The mounting plate 109 is slidably connected to the buffer rod 101. One end of the mounting plate 109 is penetrated and connected to the buffer rod 101. One end of the buffer rod 101 is connected to the protective plate 102.

[0023] The implementation principle of a high-precision instrument protection device in the embodiment of the present application is as follows: when in use, when the protection plate 102 is hit by an external object, the impact force is transmitted to the outside of the protection plate 102, and the protection plate 102 drives the buffer rod 101 to move under the impact of the external force. The protection plate 102 moves to squeeze the second spring 103, so that the second spring 103 is compressed, and the movement of the buffer rod 101 drives the pressure plate 104 to slide. Since the pressure plate 104 is slidably connected with the moving rod 105, the pressure plate 104 slides and squeezes the third spring 106, so that the third spring 106 is compressed. Since the moving rod 105 is located inside the buffer rod 101, when the buffer rod 101 moves, with the cooperation of the push plate 107, the first spring 108 and the damping rod 110 are squeezed and compressed. Under the elastic potential energy of multiple springs, the impact force of the protection is absorbed and the intensity of the impact force is reduced, thereby better protecting the outside of the instrument panel 1 and preventing the outside of the instrument panel 1 from being damaged by the impact force.
