[0027] The working principle and use process of the present invention: When in use, the present invention first installs the components on the transformer housing 1. When installing the adjusting electric box 2, the adjusting electric box 2 is placed close to the first metal block 9 so that it squeezes the second fixed block 12. One end of the second fixed block 12 slides inside the second sliding groove 14 and squeezes the spring A, causing the spring A to be deformed under force. When the second fixed block 12 is squeezed to a certain extent, the bottom end of the connecting plate 7 is just located at the opening of the first sliding groove 6. At this time, the adjusting electric box 2 is moved downward so that the connecting plate 7 is embedded in the first sliding groove 6. After being fully embedded, the second fixed block 12 is just moved to the first limiting groove 11. At this time, the spring A loses pressure and recovers its deformation, pushing the second fixed block 12, and embedding the second fixed block 12 into the first limiting groove 11 until it fits with one end of the elastic metal sheet 5. The adjusting electric box 2 is fixed. To disassemble it, a slender tool can be inserted into the first fixed groove 10, and the elastic metal sheet 5 can be pushed upward to deform and elongate. One end of the elastic metal sheet 5 pushes the second fixed block 12, so that the second fixed block 12 shrinks toward the inside of the second sliding groove 14 until it completely slides out of the first limiting groove 11, and then the adjustment electric box 2 is moved upward to make the connecting plate 7 slide out of the first sliding groove 6, and the adjustment electric box 2 is removed. If the surface of the heat sink 4 is contaminated with dust after long-term use, affecting the heat dissipation effect, the fixing rod 3 can be pulled upward, and the pulley 20 can slide inside the second limiting groove 16, so that the cleaning head 15 slides along the surface of the heat sink 4 to clean the dust on its surface. If the cleaning head 15 needs to be removed, the fixing rod 3 can be pushed to one side to shrink the telescopic joint 19, and the pulley 20 on the other side of the fixing rod 13 moves out of the second limiting groove 16, and the fixing rod 13 is removed.
