[0020] In this embodiment, during use, a single cable is passed through the cable guide device. At this time, the single cable is at an angle to the front of the outer frame 1, and it passes through both the front and back of the outer frame 1. Then, during the process of twisting the single cable into a bus, the cable guide device is controlled by the control device to move on the corresponding support 2, thereby adjusting the angle between the single cable and the bus, thus adjusting the pitch. Since one control device controls four cable guide devices, the four cable guide devices can be controlled to move synchronously on the support 2. As the cross center of the outer frame 1 of the cable guide device moves, the angle between the single cable and the bus becomes smaller and smaller, and vice versa.
