[0003] The computers used by some confidential units contain a lot of confidential information. In order to avoid leakage or damage of information, enterprises usually need to strictly control the USB ports on the computers to prevent someone from maliciously stealing information through the USB ports or implanting viruses into the computers. In reality, the USB ports are usually blocked, but this also brings certain limitations to the use of computers, that is, it is difficult to use the USB ports for data transmission. The prior art has also designed a non-standard USB adapter, which can avoid the use of conventional USB by jamming the non-standard USB adapter in the USB port, thereby further protecting the data in the computer and achieving normal data transmission through the non-standard USB adapter.

[0004] Although the above-mentioned non-standard USB adapters can meet the function of confidentiality protection, they usually cannot be removed from the USB socket. Conventional USB components cannot be used normally and can only be removed by violent destruction. However, after such removal, the USB socket will be destroyed and cannot be used. There are some non-standard USB adapters that can be removed, but most of them have complex structures and are difficult to manufacture. Utility Model Content
