[0026] Working principle:

[0027] When in use, the device can be installed at a designated position, the cable can be wound around the outside of the lead tube 11, so that the cable is wound between the wire clamping ring 6 and the fixed clamping ring 7, and then the cable can be passed through the second lead hole 10, and through the first lead hole 9 to pass the cable into the lead tube 11, and then the cable can be passed out from the top of the lead tube 11, and the cable can be led to the designated position of the transformer through the lead tube 11;

[0028] The staff can rotate the fixing bolt 20 clockwise, and the fixing bolt 20 drives the connecting rod 14 to rotate. The connecting rod 14 rotates inside the bearing 13, and the connecting rod 14 does not drive the fixing clamp ring 7 to rotate through the bearing 13;

[0029] The fixing bolt 20 moves downward through the thread, and the fixing bolt 20 drives the connecting rod 14 to move together, so that the connecting rod 14 drives the slide 4 to move through the bearing 13, so that the fixing clamp ring 7 can fit tightly with the outside of the cable, and the cable can be firmly clamped by the fixing clamp ring 7 and the lead tube 11 to prevent the cable from falling off from the outside of the lead tube 11;

[0030] During use, the staff can first pull the top plate 19 upwards, the top plate 19 stretches the fixing spring 18, and the top plate 19 drives the connecting rod 16 to move together, and the connecting rod 16 drives the fixing rod 3 to move together, and the fixing rod 3 can be taken out from the inside of the fixing hole 2, so that the limit of the wire block 5 can be released, so that the wire block 5 can move;

[0031] Then the staff can move the wire block 5, which can drive the lead tube 11 to move, so that the cable can be led to different positions of the transformer;

[0032] After the adjustment is completed, the staff releases the top plate 19. At this time, the elastic action of the fixing spring 18 pulls the top plate 19 to move downward and reset. The top plate 19 drives the connecting rod 16 to move together, and the connecting rod 16 drives the fixed plug rod 3 to move. The fixed plug rod 3 can be inserted into the corresponding fixed socket 2 on the U-shaped plate 1.
