Drainage wire temporary protection device

The utility model relates to the technical field of drainage wire protection, in particular to a temporary protection device for a drainage wire. Comprising a copper wire, two metal plate supports, two mounting bases, two guide columns, two spring pieces and two wire clamping supports, the metal plate supports are clamped above an insulating rod through clamping grooves, after one metal plate support is lifted to the wire end through the insulating rod, a pull ring is pulled downwards through a pull rope, and therefore the wire clamping supports are pulled through the guide columns, and the wire clamping supports are clamped on the metal plate supports. One metal plate support moves towards one end of the bottom of the wire clamping groove, so that the metal plate support is hung into the wire, the pull rope is loosened, the metal plate support is hung on the wire under the action of restoring force of the spring piece, the other metal plate support is lifted to the drainage wire end through the insulating ro
