Two rough-surfaced Velcro tapes are installed on a side part of the equipment screen cabinet; the two rough-surfaced Velcro tapes are placed on the same horizontal line; a face thrust Velcro tape is installed on each rough-surfaced Velcro tape; one side of the face thrust Velcro tape is provided with a fixing seat; a rotating shaft is mounted on the fixing seats; and the rotating shaft is equipped with a roller shaft. The roller shaft is installed on the equipment screen cabinet via cooperation between the face thrust Velcro tape and the rough-surfaced Velcro tapes, so an alarm sign on the roller shaft can be quickly installed on and detached from the equipment screen cabinet. The roller shaft can rotate on the rotating shaft, so the alarm sign can be quickly collected after being detached from the equipment screen cabinet and dust on the alarm sign can be prevented.
