The utility model relates to a chain easy to disassemble. The chain easy to disassemble comprises outer chain plates, inner chain plates and connecting shafts. Each outer chain plate is a hollowed-out plate with three oval through holes, and the through holes in two sides of each outer chain plate are connecting holes allowing the connecting shafts to penetrate. Each inner chain plate is an oval ring, and two ends of each ring are provided with arc bends towards one side. Each connecting shaft is a pin with two ends provided with a circular cap and an oval cap respectively, and one end, with the oval cap, of each connecting shaft penetrates through the connecting holes of the corresponding outer chain plate and the ring of the corresponding inner chain plate to connect the outer chain plates and the inner chain plates together to form a chain body. When the chain is stressed to stretch, bends of the two inner chain plates are overlapped to outwardly support the two outer chain plates to be attached onto the caps at two ends of each connecting shaft, so that stability in connection of the chain is realized. The chain easy to disassemble is simple and reasonable in structure, convenient to assemble and disassemble and stable in structure after assembly.
