Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a level ruler bracket. Background Art

[0002] Leveling, also known as "geometric leveling", is a method of measuring the height difference between two points on the ground using a level and a level rod. The level rod is a scale used to measure the height difference in leveling. The level rod must be kept in a vertical state during use. However, the most commonly used in the leveling process is the tower ruler. Most common tower rulers do not have their own level. Usually, the existing level is used to manually assist in the vertical leveling of the level rod, which is inconvenient to operate. In addition, the leveling process tests the operator's continuous stability. After leveling with the level rod, it is necessary to manually hold the ruler for a period of time. However, continuous holding of the ruler can easily cause fatigue, and unstable holding of the ruler will also affect the accuracy of the measurement.
