[0002] As the economy continues to progress, the level of science and technology is also constantly innovating and developing. Mobile phones, headphones, tablets and other electronic products have become indispensable necessities in people's lives. They provide a lot of help for life, making life more convenient, and can also enrich people's spiritual world, allowing people to understand different worlds and listen to different music without leaving home, greatly increasing people's spiritual wealth.

[0003] Among them, when using Bluetooth headsets, there is no need to worry about the wires getting tangled like in previous wired headsets, which makes it more convenient. However, it is paired with a Bluetooth headset box, which is used to charge the Bluetooth headset anytime and anywhere, so that the Bluetooth headset can be replenished anytime and anywhere, avoiding power shortage when used next time.

[0004] The shrapnel connector in the current Bluetooth headset box is prone to displacement, warping and other elastic parts during long-term use, which can easily lead to poor contact, affecting the use of the headset box and preventing the headset from charging normally.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
