The wire rope 50 has both ends and one end is fixed through the wire rope fixing hole 121 of the wire rope clip 10. Specifically, after one end of the wire rope 50 is inserted into the wire rope fixing hole 121, a portion around the wire rope fixing hole 121 is punched, and the wall of the wire rope fixing hole 121 is fixed by clamping one end of the wire rope 50 inserted into the wire rope fixing hole 121. The other end of the cable 50 is a cable penetration 122 for penetrating the cable clip 10. In other embodiments, one end of the cable 50 may be coupled to the cable fixing hole 121 by welding, screwing, bonding, or fastening.

When the preferred embodiment is used, please refer to fig. 1 and fig. 7 to fig. 8, the steel cable 50 is used to hang the steel cable type rfid tag 100 on a machine, a liquid pipeline, etc., and the information stored in the rfid chip 341 of the rfid rivet 30 can be read when checking the maintenance status of the device, so that the personnel checking the device can obtain the related data of the maintenance process of the device.
