[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] During the use of the utility model fire-resistant cable stranding machine, the stranded wires for the fire-resistant cable are stranded through the stranding machine body. During the operation of the stranding machine body, the slider can be controlled to slide on the slide frame through the driving component, so that the slider drags the left block to slide;

[0015] The left block drags the middle blocks through the connecting components, and the left block makes the left block, the middle block and the right block move away from each other, so that the U-shaped rods are separated from each other to form an isolation cover to cover the rotating arm of the stranding machine body; when the wire coil of the stranding machine body needs to be replaced, the control slider is reset, and under the squeezing action of the left block, the U-shaped rods are close to each other, thereby exposing the stranding machine body.
