When the connection hole 503 corresponds to the first fixed end 602, the first fixed end 602 is inserted into the interior of the connection hole 503 under the push of the elastic member 604, which is convenient for fixing it and preventing it from falling off. And under the action of the limiting block 603, the first fixed end 602 is limited and slides with the connecting cylinder 601 to prevent rotation. A wire is provided between the first fixed end 602 and the second fixed end 606. Similarly, the operator inserts the second wire harness 520 into the bottom of the docking end 301, so that the first wire harness 510 and the second wire harness 520 are connected.
