Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a special measuring tool for a beam correction instrument. Background Art

[0002] Measuring tool is the abbreviation of physical measuring tool. It is an instrument with a fixed form when used, used to reproduce or provide a quantitative one or more known values, such as weights, standard batteries, color temperature lamps, resistors, gauge blocks, signal generators, and single-value or multi-value measuring instruments with or without scales. Measuring tools generally do not have indicators and do not contain moving parts during the measurement process. Instead, the indicator is formed by the object being measured itself. For example, a measuring tool for measuring liquid capacity uses the upper end face of the liquid as an indicator. Although adjustable measuring tools have indicating devices, they are used for adjusting the measuring tool rather than for indicating during measurement, such as the measurement in the signal generator.

[0003] The existing technology has the following problems when used in practice:

[0004] 1. The prior art does not have a component that can make the measuring mark automatically in close contact with the beam. In the actual measurement process, the measuring personnel may need to hold the ruler to measure, which may cause errors due to the posture of the staff holding the ruler;

[0005] 2. The prior art does not have components that can be used to fix beams of different models. In actual use, the device may be unable to be widely used because the types of beams that can be fixed by the device are too single. Utility Model Content
