Description

Technical Field

[0001] This utility model relates to the field of laser level technology, and in particular to a foldable portable laser level. Background Technology

[0002] A laser level is an instrument that uses laser technology to measure horizontality. It uses a laser to generate a parallel laser beam, which is then dispersed into several straight lines by a precise optical system, forming a horizontal or vertical plane. By measuring the position of these laser lines, the position and direction of the horizontal or vertical line can be quickly and accurately determined. For example, a laser level for construction, disclosed in CN210293227U, includes a laser level with an upper connecting plate at its bottom, which is adhesively connected to the laser level. A protruding plate is located at the bottom of the upper connecting plate, and the protruding plate and the upper connecting plate are integrally formed. A circular plate is located below the upper connecting plate. The circular plate has a limiting post at its bottom end, and the limiting post and the circular plate are an integral structure. A supporting base plate is provided below the circular plate, and a sleeve is provided at the bottom end of the supporting base plate. A sliding support leg is provided on the inner side of the sleeve. The sliding support leg and the sleeve facilitate the leveling of the laser level. The sliding support leg and the sleeve allow the supporting base plate on which the laser level is placed to be quickly adjusted to a horizontal state, thereby preventing the laser level from being tilted after placement and facilitating the quick placement of the laser level. However, after prolonged use, dust will accumulate inside the docking hole of the level, and a large amount of iron powder will be attracted to the magnet, reducing the adhesion and fixing force, making the connection of the level less stable during use.
