[0002] A laser leveler is a commonly used measuring tool in the construction, decoration and other industries. It is mainly used to quickly and accurately determine the horizontal plane or straight line reference. It emits a laser beam to form a horizontal plane or plumb line within a certain range for construction workers to refer to, thereby improving construction efficiency and accuracy. Drawing vinyl lines on exterior walls is a common architectural decoration technique, mainly used to enhance the aesthetics and practicality of the building's exterior. Vinyl lines can be drawn using a laser leveler.

[0003] However, in the process of implementing relevant technical solutions, at least the following technical problems were found: during the on-site construction of the joints and glue application on the exterior walls of prefabricated buildings, the prefabricated vertical components are often manually hoisted for drawing. Coupled with the errors caused by manual layout, it is inevitable that the prefabricated components and the black glue lines of the joints are not on the same horizontal line. When drawing with a laser level, the spacing of the black glue lines of the joints cannot be determined, affecting the subsequent laying of masking tape. Utility Model Content
