A socket protection device, comprising: a shielding membrane disposed in a socket and having a diameter less than the inner diameter of the socket; and an elastic connecting band having one end fixed in the socket and the other end connected to the shielding membrane. The technical solution connects the shielding membrane to the elastic connecting band, so that the shielding membrane in use is pressed to the very bottom of the socket, and automatically returns to the starting position when the shielding membrane is no longer used, thus shielding and protecting the socket. |
