The structure is a necessary structure of the charger in the prior art.

The shell is a U-shaped shell 3, the circuit board is a U-shaped circuit board 4 corresponding to the U-shaped shell 3 in shape, and the U-shaped shell 3 encloses a swing slot 5. The advantages of the design are as follows: the traditional square shell is changed into the U-shaped shell 3, the U-shaped opening part naturally forms the swing line groove 5, so that the charger cannot be blocked by the charging wire 2 when being reset to a balanced state under the influence of gravity.

And a threading hole 6 for the power line 1 and the charging wire 2 to pass through is formed in the side wall of the swing groove 5. The technical problem solved by the design is as follows: in the prior art, the power line 1 and the charging wire 2 are respectively located at two ends of the charging box, so that the direction of the charging box can be changed due to the fact that the direction of the charging wire 2 pulled by the power line 1 is changed, and the direction of the radiating holes is changed.
