It can be explained that at least part of the charging connection line 20 close to the charging circuit is fixedly installed in the positioning portion 1111, which means that the charging connection line 20 located in the positioning portion 1111 is locked in the length direction of the charging connection line 20, and the remaining part of the charging connection line 20 outside the positioning portion 1111 is movably installed in the line clamping portion 1112, which means that the remaining part of the charging connection line 20 located outside the positioning portion 1111 can move freely.

[0051] Please see attached Figure 3In some optional embodiments, the cable clamping portion 1112 is a semi-enclosed structure with an opening in the circumference, and the two ends of the cable clamping portion 1112 are respectively provided with a first port 1113 for the charging cable 20 to pass through and a second port 1114 opposite to the first port 1113, and the charging cable 20 is detachably arranged in the cable clamping portion 1112; the charging cable 20 is detachably arranged in the cable clamping portion 1112, so that the user can take out or put back the charging cable 20 as needed when using it, and meet the user's long-distance charging needs. At the same time, the charging cable 20 can be retracted when the user charges at a close distance or does not need to use it, so as to reduce space occupation. It can be explained that the cable clamping portion 1112 is a semi-enclosed structure with an opening in the circumference, which means that the cable clamping portion 1112 forms an operating space for the user to take out the charging cable 20 or put the charging cable 20 back.

[0052] Please see attached Figure 1 In some other optional embodiments, the cable clamping portion 1112 is a circumferentially closed structure, and the two ends of the cable clamping portion 1112 are respectively provided with a first port 1113 for the charging connection line 20 to pass through and a second port 1114 opposite to the first port 1114, and the charging connection line 20 is retractably arranged in the cable clamping portion 1112. By retractably arranging the charging connection line 20 in the cable clamping portion 1112, the user can lengthen or shorten the charging connection line 20 as needed during use, thereby increasing the flexibility of use. Among them, the size design of the first port 1113 and the second port 1114 enables the charging connection line 20 to slide along its length direction, but does not allow the electrical connection seat 21 to slide into the cable clamping portion 1112. It can be explained that the cable clamping portion 1112 is a circumferentially closed structure, which means that when the charging connection line 20 slides inside the cable clamping portion 1112, at least part of it is installed in the cable clamping portion 1112, and the charging connection line 20 is limited, so that the user can lengthen or shorten the charging connection line 20. In addition, by setting the cable clamping portion 1112 as a circumferentially closed structure, the charging cable 20 is in a stored state when not in use. When the middle part of the charging cable 20 protrudes from the outside of the perforation 12 to form a carrying portion 13, when the user lifts it, a section of the charging cable 20 close to the electrical connection seat 21 is confined inside the cable clamping portion 1112, thereby avoiding the risk of the charging cable 20 falling off from the cable clamping portion 1112 when the user lifts the self-contained charging device through the carrying portion 13.
