In the actual product, a fixing member is installed on one side of the power supply housing 1 for fixing the power supply housing 1 on the surface of a designated pole or wall. By controlling the electric bolt 13 to shorten, the restrictions of the first slide rail 62 and the second slide rail 63 are released. The motor 72 is controlled to start rotating to drive the first gear 73 and the second gear 74, so that the winding roller 75 winds or relaxes the connecting rope 77, thereby realizing the lifting and moving of the "C"-shaped block 10, the slide rail block 12, and the distribution terminal housing 8. When it is necessary to check the distribution terminal housing 8, the distribution terminal in the distribution terminal housing 8 can be observed and operated without the aid of climbing tools, and the maintenance operation is convenient. After the maintenance is completed, the distribution terminal housing 8 is controlled to return to the initial position, and the electric bolt 13 is controlled to extend to fix the position of the distribution terminal housing 8.
