Further, the outer surfaces of the main rod and the auxiliary rod are provided with external threads, and the main rod and the auxiliary rods are fixedly connected by a tightening sleeve. The inner surface of the tightening sleeve is provided with internal threads, and the tightening sleeve is formed by The main rod fastening sleeve and the auxiliary rod fastening sleeve with different diameters are composed, the inner diameter of the main rod fastening sleeve is consistent with the outer diameter of the main rod, and the inner diameter of the auxiliary rod fastening sleeve is consistent with the outer diameter of the auxiliary rod.

Further, the main rod and the auxiliary rod are respectively provided with several limit holes, and the main rod and the auxiliary rod are fixedly connected by several limit bolts.

Further, the first cover frame is provided with U-shaped fixing plates parallel to the main rods every few main rods along the direction of the cable trench, and the second cover frame corresponds to the U-shaped fixing plates along the direction of the cable trench The fixed screw is provided; the U-shaped fixed plate includes a first fixed plate and a second fixed plate arranged in parallel, the first fixed plate is fixedly connected with the first cover frame, and the second fixed plate is provided with a screw that allows the Through the central hole, the outer surface of the fixing screw is provided with full threads, and the fixing screw passes through the second fixing plate on both sides and respectively provided with first nuts and second nuts.

The beneficial effects of the utility model are:

The utility model adjusts the span of the cover plate according to the width of the cable trench through the plugging of the main pole and the auxiliary pole, and can be recycled in different projects. In addition, reinforcing ribs are added to the main pole to avoid the influence of the strength when the span increases, which increases the reliability of the self-adaptive cover of the cable trench.
