Device for preventing back buckling of coiled optical cable

The utility model relates to a device for preventing back buckling of a coiled optical cable, which comprises operating rods and a base, the base is horizontally arranged and comprises at least two bottom edges which are parallel to each other, the bottom edges are respectively provided with a chute, each bottom edge is vertically provided with an operating rod, and the operating rods are in sliding connection with the chutes of the corresponding bottom edges. And the fixing device can be fixed at any position of the sliding track. According to the device for preventing the back buckling of the coiled optical cable, the optical cable is coiled around the operating rods in an 8-shaped manner, and the operating rods can reciprocate along the chutes, so that the distance between the operating rods can be adjusted by adjusting the bolts, the outer diameter of the coiled optical cable is further adjusted, and the optical cable passes through the two operating rods during coiling so as to fix the coiled optical cab
