The twisting mechanism of the tungsten wire rope adopts the epicyclic train, so that each tungsten wire can reversely and automatically rotate for one circle relative to the twisting center when the twisted tungsten wire rope is twisted for one circle, and the twisted tungsten wires are tightly wound with each other and are not easy to loosen. The twisting of the multi-strand basic strand can be completed by three layers of central strand, inner layer twisting and outer layer twisting, or the multi-layer twisting of the finished tungsten wire rope can be completed by two layers, so that the internal stress generated after the tungsten wire twisting is eliminated and the process is simplified.
