As shown in fig. 2, a plurality of strings 3 may be used to connect with the flexible rope 4 that is subjected to force by means of a winding so that the force of the flexible rope 4 may be transferred to the bypass traction means. In the construction of the electric power transmission line, a soft rope 4 is often used for paying off, the soft rope 4 is used as a primary guide rope of a wire, one end of the soft rope is connected with a traction rope of the wire, the other end of the soft rope is connected with a traction machine, and the traction machine drives the traction rope of the wire to move through the soft rope 4 so as to drag the traction rope of the wire. If the tractor fails and needs to be replaced or a connector is replaced, a bypass traction device is needed to transfer the stress of the soft rope 4 so as to fix the soft rope 4 for the purpose of replacing the tractor or the connector. Existing bypass traction devices typically employ a wire clamp to connect and secure the rope, but wire clamps are typically applied to steel ropes and have no securing effect on the flexible rope 4. Because the flexible cord 4 is deformed by the pressure of the wire clamp. The same problem occurs when the soft rope is fixed in the fields of mountain climbing, high-altitude operation and the like. The bypass traction device for the soft rope provided by the embodiment of the invention can be connected with the stressed soft rope 4 in a winding manner through the plurality of strings 3 arranged at the front end of the traction rope 1, so that the stress of the soft rope 4 can be transferred to the bypass traction device, and the bypass traction device has good stress transfer effect and fixing effect.

The winding mode is easy and convenient to operate, an operator can quickly get on the hand, the winding mode has a good fixing effect, and the winding mode is convenient to detach and fix the strings 3. As another example, in another embodiment of the present invention, as shown in fig. 2, a plurality of strings 3 may be alternately wound into a net shape by a spiral manner to connect the flexible ropes 4. The plurality of strings 3 which are staggered and wound into a net form consistent radial force on the soft rope 4, and the plurality of strings 3 are mutually pressed, so that the soft rope 4 can be well fixed, and a good stress transfer effect is achieved.
