[0029] In this embodiment, in actual use, when the power adapter body 2 is working, the generated heat is conducted to the heat conducting plate 16, and then conducted to the heat sink 17 through the heat conducting plate 16. The heat sink 17 transfers the heat to the air, and the fan 18 transfers the heat in the air out of the interior of the box body 1.

[0030] Specifically, refer to Figure 3 The inner thread of the box body 1 is connected with a threaded column 19 , and one end of the threaded column 19 located inside the box body 1 is fixedly connected with a fixing plate 20 .

[0038] Working principle:

[0039] Firstly: a conductive slip ring is installed on the top of the take-up drum 4, which is electrically connected to the connecting wire 3. The wire slip ring is provided with a connection to the winding wire 5. The winding wire 5 can be electrically connected to the connecting wire 3 in the rotating state through the conductive slip ring. When the power adapter body 2 is inside the box body 1, the winding wire 5 needs to be wound into the box body 1, and the motor 7 is started. The motor 7 drives the right gear 8 to rotate, and the right gear 8 drives the toothed synchronous belt 9. The toothed synchronous belt 9 drives the left gear 8 to rotate, and the left gear 8 drives the take-up drum 4 to rotate. The take-up drum 4 rewinds the winding wire 5, and the right gear 8 drives the reciprocating screw rod 6 to rotate, and the reciprocating screw rod 6 drives the sliding ring 10 to slide back and forth;

[0040] Then: the sliding ring 10 drives the winding wire 5 to slide back and forth, so that it cooperates with the winding drum 4 to rotate, and the winding wire 5 is evenly wound to prevent the winding of the winding wire 5 from being chaotic and causing the winding wires 5 to be entangled with each other. At the same time, the first cleaning sheet 12 and the second cleaning sheet 14 cooperate to clean the outside of the winding wire 5. When the power adapter body 2 is working, the heat generated is conducted to the heat sink 17 through the heat conduction plate 16, and is transferred to the air through the heat sink 17. The fan 18 conducts the heat in the air out of the box body 1 to maintain the normal temperature of the power adapter body 2.
