When the elastic shaft 64 runs, it will drive the rotating rope 65 to run, and the rotating rope 65 will drive the connecting slide bar 72 to run. When the connecting slide bar 72 runs, it will drive the column slot plate 71 to run, and the column slot plate 71 will pull the rotating column plate 43 to adjust the angle. At the same time, when the connecting slide bar 72 runs, it will drive the needle bar connecting rod 73 to run, and the needle bar connecting rod 73 will drive the inner scale needle rod 69 to rotate along the surface of the transverse axis 66. By observing the contact between the other end of the inner scale needle rod 69 and the surface of the inner scale plate 68, it can be observed whether the angle is adjusted correctly. At the same time, when the other elastic shaft 64 rotates, it will eventually drive the outer scale needle rod 70 to rotate along the surface of the transverse axis 66, and finally observe the adjustment angle.
