The central shaft 4 is driven to rotate through the cable arranging assembly, and the cable inside the central shaft 4 is further driven to rotate. The cable is rotated and wound on the take-up drum to realize the cable take-up. Compared with the rotary take-up of the take-up drum of the existing single twisting machine, this structure controls the rotation of the transmission wheel on the cable arranging box through motor transmission, so that the cable arranging assembly rotates. The connection between the cable arranging assembly and the connecting key 43 makes the central shaft 4 rotate, which greatly reduces the motor load and reduces the production cost. At the same time, the rotation of the cable will drive the multiple wires inside the cable to be twisted, combining twisting and taking-up, saving processes and reducing production costs.

As shown in Figure 2, a groove is also provided at the center of the end of the shaft head 42, in which a bushing 46 is inserted, and a top cone 5 is connected to the bushing 46 through a bearing.

A shaft sleeve head 32 having a smaller diameter than the shaft sleeve 31 is formed on one end of the shaft sleeve 31, and a connecting key 43 extends to the surface of the shaft sleeve head 32, thereby lengthening the connecting key 43 and expanding the connection length between the shaft head 42 and the cable assembly, so that the cable assembly can move left and right and also drive the shaft head 42 to rotate.

The other end of the central shaft 4 extends to the outside of the other end of the sleeve 31, and a transmission wheel 6 is fixed on the central shaft 4. The transmission wheel 6 is connected to the motor through a belt.
