Patent ID: 8448669

Claim:
A tube for cable sheath having a front end, a rear end, and two side plates, the tube being formed with a hollow cylinder and a hollow abutting section from the front end to the rear end in turn, the rear end being formed with a receiving space, the receiving space having an opening, the side plates being protrusive from the abutting section along an extension direction of the front end, a clamping space being formed between each of the side plates and the cylinder; wherein the clamping spaces of the side plates of the tube are adapted for an outside of the abutting section of another tube being clutched therein, the cylinder of the tube is received into the receiving space of another tube revolvingly; wherein the side plates are separately located on two opposite side of the tube, two opposite side portions of the rear end of one the tube is permanent at least partially located between either of the side plates and the cylinder of another adjacent tube when the adjacent tubes are connected together with their respective axes being coaxial or non-coaxial; wherein when the adjacent tubes are connected together, an inner circumferential surface of the rear end of one the tube engages with an outer circumferential surface of the cylinder of another adjacent tube, and the rear end of one the tube overlays the cylinder by over an half of the entire length of the cylinder of another adjacent tube; wherein as one of the two opposite side portions of one the rear end is abutted against the cylinder and one of the two side plates of another adjacent tube to position the two adjacent tubes at a fixed angle, the other opposite side portions is abutted against the cylinder and the other side plate of the adjacent tube.
