A drive motor 10 is fixedly installed inside the heat dissipation frame 6 through a connecting structure 9. The output end of the drive motor 10 is connected to a heat dissipation fan 11. The heat dissipation fan 11 is driven to rotate by the drive motor 10 to achieve the purpose of dissipating heat inside the power distribution cabinet. The upper and lower ends of the hot outlet 14 are fixedly connected with side fixing blocks 15, and the interior of the side fixing block 15 is slidably connected with a first push rod 16, one end of the first push rod 16 is located on one side of the card slot 12, and one end of the first push rod 16 is used to push the card block 13 toward the outside, so as to facilitate the card block 13 to be pulled out from the inside of the card slot 12, and the other end of the first push rod 16 is rotatably connected with a roller 19, and the middle part of the inner surface of the two sides of the cabinet 1 is fixedly connected with a top fixing block 21, and the interior of the top fixing block 21 is slidably connected with a second push rod 20, one end of the second push rod 20 is in contact with the roller 19, and is used to apply a force to the first push rod 16 toward the card block 13, and the side surface of the second push rod 20 is fixedly connected with a handle 22.

[0025] Example 1: The inner and outer ends of the heat dissipation frame 6 are detachably mounted with strip dust screens 8 by bolts, which significantly improves the air circulation efficiency and effectively filters dust, while simplifying cleaning and maintenance work, and enhancing the stability and service life of the equipment. A number of heat dissipation fins 7 are fixedly connected to the lower end of the surface of the heat dissipation frame 6, which significantly increases the heat dissipation area, improves the heat dissipation efficiency, and helps the equipment to dissipate heat quickly, thereby ensuring the stable operation of the equipment and extending its service life.
