After the measurement is completed, the one-way bearing can be driven by rotating the screw block to rotate the winding frame 14 to reel in the measuring line 15. When the winding frame 14 rotates, it will drive the sprocket 23 to rotate, and the sprocket 23 drives the sprocket 18 to rotate through the chain 25. The sprocket 18 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the moving block 19 to swing up and down with the limiting sleeve 20, and the measuring line 15 is evenly reeled on the winding frame 14. By driving the rotating ring 9 to rotate, the rotating ring 9 moves with the through hole 26 and the guide component, and the direction and angle of the two through holes 26 and the measuring line 15 can be changed, thereby improving the efficiency and accuracy of measurement.
