[0034] The measuring member 4 is connected to the transparent observation member 3 and is spaced apart from the scale 32 . The measuring member 4 is provided with at least one measuring plane 41 for contacting the structure to be measured.

[0035] The liquid storage container 1 itself can be used as a mounting structure, and the liquid storage cavity 11 of the liquid storage container 1 can be used to store liquid, so that the liquid can be tested and used multiple times. The conductive member 2 is connected to the liquid storage container 1, and the transparent observation member 3 is connected to the conductive member 2, so that the three can be connected. The conductive member 2 is provided with a conductive channel 21, and the first opening 211 and the second opening 212 of the conductive channel 21 are respectively connected to the bottom of the liquid storage cavity 11 and the bottom of the observation cavity 31 of the transparent observation member 3, so that the liquid stored in the liquid storage cavity 11 can flow from the conductive channel 21 to the observation cavity 31 of the transparent observation member 3. According to the principle of communicating vessels, the liquid in the liquid storage container 1 can enter the observation cavity 31 of the transparent observation member 3 until the liquid level in the liquid storage container 1 is flush with the liquid level in the observation cavity 31. From the transparent observation member 3 set to be transparent, the height of the liquid in the observation cavity 31 is observed. Then, the scale 32 value corresponding to the height of the liquid level in the observation cavity 31 is observed through the scale 32 on the surface of the transparent observation member 3. The measuring piece 4 connected to the transparent observation piece 3 and spaced from the scale 32 will not affect the observation of the scale 32, and the measuring plane 41 on the measuring piece 4 that contacts the structure to be measured can be used for leveling or measuring errors. When in use, the measuring plane 41 can be used as a reference, and when leveling is required, the structure to be leveled is made flush with the measuring plane 41. For the structure to be measured, the height of at least two positions where the structure to be measured needs to be flush can be measured, and according to the difference in the displayed values, it can be judged whether there is a large height error in the structure to be measured.
