[0025] Working principle:

[0026] When in use, the connecting plate 101 is installed on the mobile device through the through hole, and then the connecting plate 101 is moved to the top of the power transformer to be hoisted by the mobile device, and then the threaded motor 115 is started to drive the threaded shaft 116 to rotate, and then the two threaded blocks 117 are driven to move closer to or away from each other through the thread, and then the two moving shafts 118 are driven to move through the two moving shafts 118 until the two hoisting hooks 123 correspond to the hoisting position of the power transformer;

[0027] When hoisting the power transformer, the winding motor 119 is started to drive the winding wheel 121 to rotate, and then the hoisting rope 122 is loosened, so that the hoisting hook 123 moves downward, so that the hoisting position of the hoisting hook 123 and the power transformer is fixed, and then the winding motor 119 is started to drive the winding wheel 121 to rotate in the opposite direction, and then the hoisting rope 122 is wound, and then the power transformer is hoisted and suspended;
