[0001] The present invention relates to the technical field of power banks, and in particular to a universal power bank with a function of clamping a mobile phone. Background Art

[0002] Power banks are a type of mobile power source that allows people to temporarily charge their mobile phones, tablet computers, watches and other devices. Power banks are very common nowadays. Whether they are office workers or people traveling for fun, almost everyone has one. However, as the capacity of milliamperes increases, power banks are also getting heavier and larger, making them inconvenient to carry. You have to carry a data cable with you. In addition, power banks currently on the market usually do not have a mobile phone clamping function. Although some design solutions for power banks with mobile phone clamping functions have been proposed, the following problems still exist:

[0003] (1) The mobile phone is clamped by a spring. When clamping a small mobile phone, the clamping force is too small and it is easy to fall off. When clamping a large mobile phone, the elastic force is too large and it is not easy to clamp;

[0004] (2) It can only be used on designated mobile phones and cannot be used on other mobile phones, making it impossible to share it with others;

[0005] (3) The action of holding the phone is rather cumbersome, and it is difficult to remove it after charging is completed. If it is not removed, it will affect the feel of using the phone;

[0006] (4) The clamping mechanism is clamped on both sides of the mobile phone, which can easily touch the mobile phone buttons or block the use of the mobile phone buttons;

[0056] When the present invention is not in use, the clamping member A3 can rotate along the threaded hole below the shell, and the clamping member B can rotate along the threaded hole D on the bracket. The buckles 301 of the clamping members A3 and the clamping members B are flush with the shell. When in use, the clamping members A3 and the clamping members B are rotated to make the clamping members A3 and the buckles 301 on the clamping members B perpendicular to the shell, and the hand-tightening bolt is twisted to increase the distance between the drive bracket and the cover plate 12, that is, the distance between the clamping members B and the clamping members A3 is increased, and the mobile phone is placed between the clamping members B and the clamping members A3, and the hand-tightening bolt is slightly twisted in the reverse direction to further clamp the mobile phone, and the charging head 1 is pulled out, and the charging connector 102 is connected to the mobile phone. Turn on the power switch to charge the mobile phone.
