The semicircular angle ruler 20 is provided with an angle indication line 31, and zero scale lines of the angle indication line 31 coincide with the circle center of the semicircular angle ruler 20.
Through the arrangement, after the first vertical rod 10 and the second vertical rod 70 are placed on the shield segment to be tested, the first vertical rod 10 and the second vertical rod 70 have a height difference due to the inclination angle of the shield segment to be tested, at this time, the rubber rope 60 directly generates an offset on the semicircular angle ruler 20 due to the height difference between the first vertical rod 10 and the second vertical rod 70, and the angle indication line 31 overlapped with the rubber rope 60 is the inclination angle of the shield segment to be tested after being installed.
