[0041] Specifically, the limiting assembly 9 includes a first groove 902 opened inside the fixed block 8 and a second groove 907 opened inside the second receiving groove 19. A first spring 901 is fixed inside the first groove 902, and one end of the first spring 901 is connected to a first movable block 903. A buffer plate 904 extending to the outside of the fixed block 8 is installed on one side of the first movable block 903. When the buffer plate 904 is squeezed by the data transmission head 7, it will move and push the first movable block 903 to move, so that the first movable block 903 squeezes the first spring 901. The buffer plate 904 is slidably connected to the first groove 902 through the first movable block 903, so that when the buffer plate 904 moves, it can drive the first movable block 903 to slide inside the first groove 902.

[0042] Specifically, a second spring 908 is fixed inside the second groove 907, one end of the second spring 908 is connected to a second movable block 906, and a baffle 905 extending to the inside of the second receiving groove 19 is fixed on one side of the second movable block 906.

A data transmission head 7 is installed at one end of the data cable 10. The data transmission head 7 can be stored in the second storage slot 19.

[0044] Embodiment 2:

[0045] On the basis of the above-mentioned first embodiment, since the bracket 12 needs to be limited after being received in the receiving chamber 11 to prevent it from being rotated out of the receiving chamber 11 at will, the following structure is provided.

[0046] See also Figure 4-Figure 5 A first magnetic block 14 is installed on one side of the bracket 12, and a second magnetic block 15 is installed on the inner wall of the storage cavity 11. A through groove 16 is opened on the bracket 12, and the first magnetic block 14 is fitted with the second magnetic block 15. The first magnetic block 14 and the second magnetic block 15 function to limit the bracket 12, prevent the bracket 12 from rotating at will, and improve the stability of the bracket 12.

[0047] The working principle of the utility model is as follows: first, when the power bank needs to be used, the corresponding USB plug can be rotated so that the first USB plug 5 or the second USB plug is rotated out from the first storage slot 3, and then inserted into the USB interface of the corresponding device, and the power switch 20 is pressed to charge the device; after charging is completed, the first USB plug 5 or the second USB plug can be rotated in the opposite direction so that the first USB plug 5 or the second USB plug is rotated into the first storage slot 3, and the port of the first USB plug 5 or the second USB plug is inserted into the card slot 6, so as to achieve the purpose of storing the first USB plug 5 or the second USB plug;

[0048] When the bracket 12 is needed, the user can forcefully rotate the bracket 12 to separate the first magnetic block 14 from the second magnetic block 15, so that the bracket 12 can be rotated out of the storage chamber 11. When the bracket 12 is not needed, the bracket 12 can be rotated in the opposite direction to rotate the bracket 12 into the storage chamber 11, and the first magnetic block 14 and the second magnetic block 15 can be fitted together, so that the bracket 12 can be limited to prevent the bracket 12 from rotating at will.

[0049] When the data transmission head 7 is needed, the baffle 905 can be pushed first, so that the baffle 905 moves into the second groove 907, and the second movable block 906 squeezes the second spring 908. After the baffle 905 no longer limits the data transmission head 7, the data transmission head 7 can be taken out from the second receiving groove 19; when the data transmission head 7 is not needed, the data transmission head 7 can be stored in the second receiving groove 19, and the baffle 905 is released at this time. The second spring 908 stretches and pushes the second movable block 906 to reset and move, and drives the baffle 905 to reset, so that the baffle 905 contacts the top of the data transmission head 7, so as to limit the data transmission head 7 and prevent the data transmission head 7 from being moved out of the second receiving groove 19 at will;

[0050] When the data transmission head 7 is stored in the second storage slot, the data transmission head 7 will contact the buffer plate 904. If the user carries the power bank by holding the data cable 10, the data transmission head 7 will be pulled to move and squeeze the buffer plate 904. After the buffer plate 904 is squeezed, it will move and push the first movable block 903 to move, so that the first movable block 903 squeezes the first spring 901. The first spring 901 is compressed to buffer the squeezing force applied by the data transmission head 7, thereby protecting the data transmission head 7.
