[0025] Initially, the first telescopic cover 321 and the second telescopic cover 322 are overlapped and stored in the fixed cover 31. After the USB plug 21 is inserted to the outside of the charging port 11, the positioning component 33 adjusts the positions of the first telescopic cover 321 and the second telescopic cover 322, so that the first telescopic cover 321 and the second telescopic cover 322 are pulled out of the fixed cover 31 in sequence and sleeved on the outside of the USB plug 21.

When the USB plug 21 needs to be protected, the first telescopic cover 321 and the second telescopic cover 322 are pulled out in turn and sleeved on the outside of the USB plug 21. At this time, the guide block 332 and the first magnetic block 333 are fitted with each other, and the first magnetic block 333 fixes the position of the guide block 332 through magnetic attraction, and then fixes the positions of the first telescopic cover 321 and the second telescopic cover 322.

[0036] During charging, the charging sheet 22 is inserted into the charging port 11. At this time, the USB plug 21 is synchronously inserted into the outside of the charging port 11. The USB plug 21 is between the two sets of fixed covers 31. The first telescopic cover 321 and the second telescopic cover 322 are pulled out in turn and sleeved on the outside of the USB plug 21. At this time, the guide block 332 and the first magnetic block 333 fit each other. The first magnetic block 333 fixes the position of the guide block 332 through magnetic attraction and then fixes the position of the first telescopic cover 321 and the second telescopic cover 322. The first telescopic cover 321 and the second telescopic cover 322 can provide all-round safety protection for the USB plug 21, and can effectively prevent the USB plug 21 from being squeezed and deformed by the outside. When the charging sheet 22 and the charging port 11 loosen and slide off, it can effectively prevent the USB plug 21 from being completely separated from the mobile power body 1, and prevent the mobile power body 1 from falling directly.
