Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a level measuring instrument. Background Technology

[0002] A level is a tool used to measure whether an object or surface is horizontal or vertical. It is widely used in construction, decoration, engineering construction, and industrial equipment installation to ensure that components or structures meet design requirements, achieving precise installation and calibration.

[0003] For example, a level measuring instrument described in patent publication number CN220751160 U has the following design: A protective sleeve, a sliding groove, a protrusion, a mounting base, and a spring are incorporated. During use, the protective sleeve covers both ends of the level measuring instrument. If the level measuring instrument is accidentally dropped, the spring inside the protective sleeve provides cushioning and protection. The telescopic column and handle allow the telescopic column to be pulled outwards by gripping the handle. The friction between the telescopic columns helps maintain a certain height. The telescopic column can be adjusted according to the worker's height, avoiding frequent bending. To retract the instrument, the handle is pressed down to return the telescopic column to its initial position.

[0004] The above-mentioned technologies are mainly for the detection of horizontal or vertical walls. When it comes to the detection of inclined or curved surfaces, it is difficult to achieve the detection and it is not convenient to adjust according to different detection requirements. At the same time, the hanging rope in the above-mentioned technologies mainly serves the purpose of portability. When the equipment needs to be stably installed on non-planar, inclined, vertical, or curved surfaces, it is difficult to fix the ruler by hanging rope alone. Utility Model Content
