The invention discloses a combined type dragging chain. The combined type dragging chain comprises a number of chain links and encapsulation blocks installed corresponding to each chain link. The chain links are connected end to end so that a long-strip dragging chain body is formed. The encapsulation blocks and the corresponding chain links are combined and installed into an enclosed ring shape for installation of cables. Adjacent encapsulation blocks are interconnected through flexible parts. The portion of the dragging chain links and the portion of the encapsulation blocks are combined respectively, and then the dragging chain links and the encapsulation blocks are used in combination so that rapid installation and disassembling of the chain links and the encapsulation blocks can be achieved, and cables can be conveniently placed in the dragging chain and put into use; the dragging chain can also be rapidly disassembled integrally so that cables can be replaced, disassembled and assembled; installation and use efficiency of the dragging chain is improved greatly; and the dragging chain is adaptive to the industrial high-speed process.
