A rotating block 3 is fixedly welded on the outer side of the rotating shaft 7. A connecting block 4 is fixedly welded at one end of the rotating block 3. A guide wheel 5 is rotatably installed inside the other end of the connecting block 4. Steel moves between the two guide wheels 5 on both sides to limit the steel. The upper part of the rotating shaft 7 penetrates through the guide body 1 and is fixedly welded with an outer pulling rod 17. An inner pulling rod 14 is slidably installed inside the outer pulling rod 17. The other end of the inner pulling rod 14 is rotatably installed with a moving block 11. A first lead screw 9 is threadedly connected to the middle of the moving block 11. An installation frame 8 is fixedly welded on the upper part of the guide body 1. One end of the first lead screw 9 is rotatably connected to the installation frame 8. The other end of the first lead screw 9 penetrates through the installation frame 8 and is fixedly welded with a first rotating cap 10. By rotating the first rotating cap 10 to drive the first lead screw 9 to rotate, the moving block 11 moves back and forth. By driving one end of the inner pulling rod 14 to move and rotate, the inner pulling rod 14 moves along the inside of the outer pulling rod 17 and drives the outer pulling rod 17 to rotate. The rotating block 3 is driven to rotate by the rotating shaft 7, so as to change the distance between the guide wheels 5 and realize the adjustment of the guide assembly 1;

[0020] A limiting groove 18 is provided in the upper part of the guide body 1. A limiting block 19 is fixedly welded to the lower part of the moving block 11. The limiting block 19 is slidably installed inside the limiting groove 18 to prevent the first lead screw 9 from driving the moving block 11 to rotate. Connecting seats 12 are fixedly welded to both sides of the moving block 11. Two sets of upper and lower connecting pieces 13 are fixedly welded to the side of the inner pulling rod 14 close to the moving block 11.
