After the rotating plate 7 is rotated to fit between the corresponding socket on the external wall, the rotating plate 7 helps to limit the corresponding socket on the external wall and the power adapter body 1, so that the power adapter body 1 can be used stably and reliably when in use. After the power adapter body 1 is inserted into the corresponding socket, the power adapter body 1 can be prevented from being skewed, so as to prevent the power adapter body 1 from having poor contact due to skew when in use, which helps to use the power adapter body 1 normally.

[0031] Among them, first limiting pads 5 are fixed to the inner surfaces at both ends of the first retaining groove 2 on the power adapter main body 1, and the first limiting pads 5 are in a matching and fitting state with the relative surfaces at the corresponding positions in the first retaining groove 2 on the power adapter main body 1, and the power adapter main body 1 can fix and limit the first limiting pads 5; the two end surfaces of the rotating plate 7 are in a matching and fitting state with the relative surfaces of the corresponding first limiting pads 5, and a fixing rod 4 is fixed between the bottoms of the inner surfaces at both ends of the first retaining groove 2 on the power adapter main body 1, and the power adapter main body 1 can fix and limit the fixing rod 4.

[0032] The fixing rod 4 is in a horizontal state, and the fixing rod 4 passes through the two side surfaces of the corresponding position on the first limiting pad 5. The first limiting pad 5 is provided with a matching second through hole 10 corresponding to the fixing rod 4. The second through hole 10 on the first limiting pad 5 helps to limit the fixing rod 4 and the first limiting pad 5; the middle part of the rotating plate 7 close to one end of the fixing rod 4 is provided with a first through hole 9 corresponding to the fixing rod 4. The first through holes 9 pass through the two end surfaces of the corresponding position on the rotating plate 7. A second limiting pad 6 is fixed in the first through hole 9 on the rotating plate 7, and the rotating plate 7 can fix and limit the second limiting pad 6.

[0033] The inner ring surface of the first through hole 9 on the rotating plate 7 is in a matched and fitted state with the outer ring surface of the corresponding second limiting pad 6, and the inner ring surface of the second limiting pad 6 is in a matched and fitted state with the outer ring surface of the corresponding fixed rod 4, and the second limiting pad 6 helps to limit the first through hole 9 on the rotating plate 7 and the fixed rod 4; a matching second retaining groove 3 is provided on the corresponding heat sink 11 on the power adapter body 1, and a plurality of heat sinks 12 are spaced apart on the side surface of the heat sink 11 away from each other, and a connecting plate 8 is fixed to the middle part of the surface of the end of the rotating plate 7 away from the fixed rod 4, and the connecting plate 8 helps to rotate the rotating plate 7, so as to facilitate the use of the rotating plate 7.

[0034] The working principle of the utility model is: during use, when the power adapter body 1 needs to be used, the power adapter body 1 is inserted into the corresponding socket on the external wall, and the power adapter body 1 is connected to the line that needs to be connected to the outside world, so that the power adapter body 1 can be used, and the connecting plate 8 is further pushed toward the side away from the middle of the power adapter body 1. When the connecting plate 8 is pushed, it will drive the rotating plate 7 to rotate toward the side away from the middle of the power adapter body 1.

[0035] When the rotating plate 7 rotates, it will rotate between the first limiting pad 5 in the first retaining groove 2 on the power adapter main body 1. The first limiting pad 5 helps to limit the first retaining groove 2 on the power adapter main body 1 and the rotating plate 7, so that there is friction resistance between the first retaining groove 2 on the power adapter main body 1 and the rotating plate 7. When the rotating plate 7 rotates, it will drive the second limiting pad 6 in the first through hole 9 to rotate. When the second limiting pad 6 rotates, it will rotate along the outer side of the fixed rod 4. The power adapter main body 1 can fix and limit the fixed rod 4, which is convenient for the stable use of the fixed rod 4. The fixed rod 4 can limit the rotating plate 7 through the second limiting pad 6 in the first through hole 9 on the rotating plate 7, which helps to stably rotate the rotating plate 7.

[0036] The rotating plate 7 is rotated to fit with the corresponding position on the corresponding socket on the external wall. The second limiting pad 6 helps to create friction resistance between the rotating plate 7 and the fixed rod 4, so as to facilitate the positioning of the rotating plate 7 after the rotation is completed. The rotating plate 7 helps to limit the power adapter body 1 and the corresponding socket on the external wall, avoiding the power adapter body 1 from being skewed during use, which helps to use the power adapter body 1 normally.

[0037] After rotating the rotating plate 7 to fit with the corresponding socket on the external wall, the heat sink 11 in the second retention groove 3 on the power adapter main body 1 is in contact with the external air, and heat is generated when the power adapter main body 1 is used. The heat sink 11 in the second retention groove 3 on the power adapter main body 1 and the heat sink 12 on the heat sink 11 help to dissipate the heat generated on the power adapter main body 1, which can prevent the accumulation of heat on the power adapter main body 1 and help to use the power adapter main body 1 normally.

[0038] During use, it is convenient to use the power adapter main body 1 stably and reliably. After the power adapter main body 1 is plugged into the corresponding socket, the power adapter main body 1 can be prevented from being skewed, so as to prevent poor contact due to the skewness of the power adapter main body 1 when it is used, which is conducive to the normal use of the power adapter main body 1.
