[0036] Specifically, the device provides stable support through the base 1, and the two mounting columns 2 on the top jointly support the mounting seat 5, and the position height of the mounting seat 5 is adjusted by a fixed adjustment component 1 to cooperate with the lower ring seat 11 at the bottom to adjust the division coefficient of the measurement data. An upper ring seat 6 is fixed to the outer wall of the mounting seat 5, and a glass layer 7 and an eccentric magnifying glass 8 are installed in the middle of the upper ring seat 6.

[0044] Please refer to the attached Figure 2 The three-claw centering assembly includes three centering bolts 18. The outer walls of the three centering bolts 18 are threadedly connected to the middle of the lower ring seat 11, and the three centering bolts 18 are equipped with centering heads 19 at one end thereof.

[0045] Specifically, during the measurement process, in order to ensure that the position of the cable to be measured is fixed and the cross vertical line on the dial 13 is aligned with the cable point, the centering bolt 18 is rotated to push the centering head 19 toward the outer wall of the cable to be measured and fix it by clamping in three directions.
