Description

Technical Field

[0001] The utility model relates to the technical field of cable storage tools, in particular to an iron-wooden drum for cable storage and release. Background Art

[0002] Cable reels are tools used to wind and store cables. After production, the cables are wound on the cable reels and stored in rolls for easy transfer and transportation. Existing cable reels are usually in the form of wire drums, which are used to wind cables. At both ends of the wire drum, wire drums are usually provided.
