[0024] See also Figure 1-Figure 5 In order to straighten the cable, ensure that the annular groove 11 fits the cable, and adjust the distance between the dynamic pressure roller 6 and the fixed pressure roller 9, the two vertical plates 2 are each provided with an adjustment groove 8, and an adjustment block 10 is provided inside the adjustment groove 8 through an electric push rod 12. The adjustment block 10 can slide up and down in the adjustment groove 8, and the adjustment block 10 is rotatably connected to the dynamic pressure roller 6 through a rotating rod 7. In order to ensure the stability of the adjustment block 10 sliding up and down in the adjustment groove 8 to avoid falling off or offset, sliding columns 14 are welded on the two side walls of the adjustment block 10, and the inner wall of the adjustment groove 8 is provided with a sliding groove 13 for facilitating the sliding column 14 to slide up and down.

[0025] See also Figure 1-Figure 5 In order to facilitate the marking and measurement of the length of the cable, a sliding cavity 20 of a measuring mechanism is provided in the annular groove 11 of the dynamic pressure roller 6, and a movable plate 18 of a sliding assembly is slidably provided in the sliding cavity 20. The movable plate 18 is connected to the bottom end of the sliding cavity 20 by a spring 19, and a sliding rod 16 is welded to the other end, and the sliding rod 16 slides out of the sliding cavity 20, and a socket 17 for convenient insertion of the marking member 15 is provided inside it. The marking member 15 can be chalk or a marker, etc., and the length of one circle of the dynamic pressure roller 6 with the marking member 15 can be 50 cm, or other lengths, so that when the cable is pulled, the dynamic pressure roller 6 and the fixed pressure roller 9 can be rotated, so that the cable can be straightened and marked at a fixed point, and the length can be measured, which is more convenient.

[0026] Working principle: When the utility model is used to measure the cable, the cable is first passed through the conical cleaning sleeve 21 and then through the guide ring 5. The cable can be cleaned first to remove dust and other impurities on the surface. At the same time, the guide ring 5 can be guided and straightened, and then pass through the annular groove 11, extend through the electric push rod 12, and slide the adjustment block 10 in the adjustment groove 8. The slide column 14 slides in the slide groove 13 to ensure the stability of the movement. Then the dynamic pressure roller 6 approaches the fixed pressure roller 9. The cable can be limited and guided through the annular groove 11, and the cable can be pulled (it can be pulled by a traction device, etc.). At this time The cooperating rotating rod 7 can rotate with the fixed pressure roller 9 and the dynamic pressure roller 6. On the one hand, the cable can be guided and straightened. On the other hand, when the marking piece 15 rotates to the bottom, it contacts the cable and can mark it. At the same time, an extrusion force is generated on the sliding rod 16, which causes the movable plate 18 to slide in the sliding cavity 20. The spring 19 contracts under the force to store potential energy, which does not affect the rotation and guiding operation. After continuing to rotate, the marking piece 15 loses contact with the cable and is reset under the action of the potential energy of the spring 19, which is convenient for the next marking operation. The cables can be marked at equal distances, and then the length of the cable can be measured, which is convenient for subsequent construction use.
