A telephone line box includes a telephone line, a housing and a cable chassis. The telephone line includes two telephone plugs and a belt-type cable connected between the two plugs. The housing includes a cylindrical slot in it, two openings located on one end of the housing for placing the two plugs, and one cable path between each of the openings and the cylindrical slot for allowing the cable to pass through. The cable chassis is rotatably positioned in the cylindrical slot of the housing having a disc and a reel installed at the center of the disc. The cable is divided into two parts separated by a middle portion that is fixed to the reel. When the cable chassis is rotated along a specific direction to collect the two parts of the cable through the two cable paths of the housing, the two parts of the cable will be wrapped around the reel through two neighboring entry positions in the cylindrical slot, and the two cable paths are arranged along two tangential directions extended from the two entry positions of the cylindrical slot. When one part of the cable is pulled out of the cylindrical slot along one cable path, the other part of the cable will be smoothly carried out through the other cable path in the same time without becoming tangled.
