Casing structure of cable reel

Abstract

A casing structure of a cable reel includes a hollow main body, which has two ends communicating with the outside and an interior space rotatably receiving therein a reciprocal rotary disk that receives therein a cable having first and second end sections in such a way that the first and second end sections of the cable extend out of the main body through the two ends of the main body. The main body has at least one first through opening in communication with the interior space of the main body. The first and second end sections of the cable are provided with predetermined colors so that when the first and second end sections of the cable are selectively pulled, a visual effect caused by reciprocal rotation of the first and second end sections of the cable is observable through the first through opening.
