Plug interface protection structure for computer case

The utility model relates to the field of computer interface protection, and discloses a plug interface protection structure for a computer case. Computer interface protection is set, when a USB interface needs to be used, the outer surface of a sliding shaft fixedly installed over the USB interface rotates towards a rotary button, a sliding baffle fixedly connected with the outer surface of the sliding shaft is driven to rotate on the outer surface of a sliding supporting column, and the angle can be freely adjusted during use; when a small device such as a small USB flash disk is connected, the angle can be adjusted to be small so that the device can be prevented from loosening or falling off due to the fact that the connected device is touched in the using process, the multiple sockets correspond to the multiple baffles, the angle of the unused sockets can be adjusted to be closed so that dust and tea water can be prevented from being spilled in, and then the containing box is fixedly installed under the U
