The airflow will take away the heat on the surface of the transformer body 16, and then discharge it outward through the heat dissipation ports 5 on the side guard plates 2 on both sides, so as to achieve heat dissipation of the transformer body 16. When encountering bumps during driving, the transformer body 16 slides on the top of the base plate 1, so that the push plate 14 squeezes the connecting rods 13 on both sides to push the slider 10 to slide to both sides of the slide bar 9 and squeeze the first spring 11, and the opposite end of the slider 10 will stretch the second spring 12, and the second spring 12 will weaken part of the force during the stretching process, and the first spring 11 will buffer the remaining force during the squeezing process, thereby reducing the amplitude of the shaking of the transformer body 16 and reducing the possibility of damage to the transformer body 16.
