Technical Field

[0001] This utility model relates to a level, specifically a short level with good accuracy and stability. Background Technology

[0002] A spirit level is a common measuring tool, used for 95% of measurements, including horizontal and vertical alignment. It is widely used in construction, machinery installation, carpentry, and other fields. In recent years, with the increasing sophistication of daily life and production, short spirit levels have become increasingly popular due to their small size, ease of storage, and portability. However, the compact design of short spirit levels often limits their functionality, resulting in simple product designs. Their small size also makes them prone to being carelessly dropped or misplaced, leading to accidents such as collisions and falls. Furthermore, existing short spirit levels suffer from limited protection points and poor reliability, with the bubble level holder sometimes becoming loose, causing variations in bubble level accuracy.
