The resistance assembly 83 is fixedly connected to the surface of the ceramic medium body 1, and includes a slide cylinder 831 and a hinge block 834. The slide cylinder 831 is fixedly connected to the surface of the ceramic medium body 1, and the slide cylinder 831 is internally slidably connected to a sliding plate 832, and the side of the sliding plate 832 away from the inside of the slide cylinder 831 is fixedly connected to a sliding rod 833, and the end of the sliding rod 833 away from the sliding plate 832 is fixedly connected to the inner side of the protective cover 81, and the side of the sliding plate 832 is hinged with a contact rod 835 through the hinge block 834, and the front end of the contact rod 835 is fixedly connected to an elastic rope 836, and the end of the elastic rope 836 away from the contact rod 835 is fixedly connected to the side of the sliding plate 832, and a deceleration block 837 is fixedly connected to the inner wall of the slide cylinder 831.
[0025] The protective cover 81 is located outside the ceramic dielectric body 1 and is made of silicone. When the ceramic dielectric body 1 is impacted, it will first contact the protective cover 81. The protective cover 81 made of silicone has a certain elasticity and can buffer the impact force generated by the impact.
[0026] The protective cover 81 is provided with openings near the feed pin 4 and the tough connecting belt 6, and ventilation holes are provided on both sides of the protective cover 81. The protective cover 81 will not affect the operation of the tough connecting belt 6 and the feed pin 4, and the ventilation holes can help dissipate heat.
[0027] There are eight buffer springs 82 in total, and each buffer spring 82 is grouped into two and is respectively located on the four sides of the ceramic dielectric body 1 . The eight buffer springs 82 can absorb the impact force when the four sides of the ceramic dielectric body 1 are hit.
[0028] The end of the contact rod 835 away from the sliding plate 832 is arc-shaped, and the end of the contact rod 835 away from the sliding plate 832 is close to the deceleration block 837 .

[0030] A specific application of this embodiment is: the ceramic dielectric body 1 is installed on the drone by stretching the tough connecting belt 6 and the mounting plate 7. When the ceramic dielectric body 1 is hit on all sides, it will first contact the protective cover 81. The protective cover 81 made of silicone material has a certain elasticity and can buffer the impact force generated by the impact. At the same time, the eight buffer springs 82 will also absorb the impact force when the ceramic dielectric body 1 is hit on all sides and gradually tighten. At this time, the sliding rod 833 is driven by the force to drive the sliding plate 832 to move inside the sliding cylinder 831. When the contact rod 835 moves with the sliding plate 832, its arc-shaped The end will contact the speed reduction block 837. At this time, the contact rod 835 will be deflected without generating too much resistance. When the buffer spring 82 rebounds and drives the sliding rod 833 and the sliding plate 832 to move in the opposite direction and restore, the contact rod 835 follows the sliding plate 832 to move and contact the speed reduction block 837 again and cannot deflect. At this time, the arc-shaped end of the contact rod 835 is squeezed with the rubber speed reduction block 837 to generate resistance, which slows down the speed and amplitude of the buffer spring 82 when it rebounds, and prevents the buffer spring 82 from rebounding too fast and causing shock again, thereby better protecting the ceramic medium body 1.
