Problems solved by technology

When the operator uses the computer, his feet will often step on the USB cable or be entangled by the USB cable. When the operator needs to get up, it is easy to cause a sudden force on the USB cable, disconnect the connection with the host computer and shorten the service life of the keyboard.
