The invention relates to the technical field of network cables, and discloses a screw protection device capable of avoiding transverse vibration and cooling. The screw protection device comprises a rack, a rotating shaft is rotationally connected in the rack, a mounting disc is rotationally connected to the outer side of the rotating shaft, a supporting column is fixedly connected to the surface of the mounting disc, an elastic cavity is fixedly connected to the end, away from the mounting disc, of the supporting column, a water inlet hole is fixedly connected to the outer side face of the elastic cavity, a push rod is fixedly connected into the elastic cavity, and a metal contact is fixedly connected to the end, away from the elastic cavity, of the push rod. Through movement of the elastic cavity, the elastic cavity is compressed, so that the resistance, connected into the interior of the elastic cavity, of an electromagnetic rod is reduced, the electromagnetic rod and a magnetic block are close to each other, and a solution in the elastic cavity enters a water bin through a water through hole, so that vibration can be automatically filtered during slight vibration, and balance weights on the two sides of the protection device can be automatically adjusted during serious vibration, so that vibration is reduced.
