The depths of the first rotating groove and the second rotating groove are the same. When connecting, it improves the connection effect of the drag chain sections, and the overall structure is simple and tidy, improving the use effect. When in use, the seven sets of drag chain sections are sequentially rotatably connected end to end. One end of the drag chain section is detachably connected to the fixed cylinder 1 through a quick-release component, and a fixed seat 7 is rotatably arranged at the other end of the drag chain section. The fixed seat 7 is a hollow structure, and a fixing plate is fixedly arranged on the outer wall of the fixed seat 7. A through hole is opened on the fixing plate to facilitate fixing the other end of the drag chain section on the refrigerator; the drag chain section includes symmetrically arranged chain plates 2. The inner walls of the bottoms of the two chain plates 2 are fixedly connected through an inner cover plate 203. An outer cover plate 3 is detachably arranged on the inner wall of the top of the chain plate 2. First slots 204 are opened on the inner walls of the tops of the two chain plates 2. First plug-in plates 301 are fixedly arranged at both ends of the outer cover plate 3. The two first plug-in plates 301 are respectively inserted and connected with the corresponding first slots 204. During the wire threading process, the outer cover plate 3 can be removed from the chain plate 2, and then the wire harness is arranged inside the chain plate 2, improving the wire threading efficiency. When in use, by fixedly arranging the first plug-in plates 301 at both ends of the outer cover plate 3 and opening the first slots 204 on the chain plate 2, it is convenient for the installation and disassembly of the outer cover plate 3, thus facilitating the installation of the wire harness inside the chain plate 2 and also facilitating the arrangement of the wire harness inside the chain plate 2, improving the use effect; multiple sets of partition rods 401 are slidably arranged on the inner wall of the inner cover plate 203.
