After the two protective covers 203 have made semi-circular motions, the two protective covers 203 are completed and completely cover the surface of the ruler 1 and the box body 101. At this time, the rectangular ring 3 can be manually inserted to fix the splicing of the two protective covers 203.

[0077] Example 3:

[0078] See also Figure 1-Figure 5 Based on Example 1, this embodiment provides a portable measuring ruler for silver mine surveying projects that can achieve finer measurement accuracy. The specific concept is as follows:
