[0027] Example 2

[0028] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an adjustment structure is provided between the first measuring ruler 1 and the second measuring ruler 2;

[0029] The adjusting structure controls the movement of the second measuring scale 2 by stretching, and the adjusting structure is used to adjust the angle between the first measuring scale 1 and the second measuring scale 2. The adjusting structure includes an adjusting slot 3, which is opened inside the second measuring scale 2 and extends to the bottom of the second measuring scale 2. A sliding plate 4 is slidably connected inside the adjusting slot 3, and the sliding plate 4 is set as an annular structure. A connecting column 5 is set inside the sliding plate 4.
