Background
The laser line projector (also called laser line marker) is an instrument which utilizes laser beams to form a fan-shaped laser surface through a cylindrical lens or a glass rod and projects and forms horizontal and/or vertical laser lines, and is widely used in the fields of decoration and the like as an auxiliary tool for horizontal or vertical alignment of construction. When using a laser marker, sometimes only one horizontal line is needed, and the position of a point is marked on the horizontal line, i.e. the mark is made. For example, when hanging a plurality of pictures, it is necessary to make a plurality of pictures hung on a reference (e.g., a wall surface) on a horizontal plane. In addition, when a plurality of pictures are hung, the hung pictures are required to be spaced apart by a certain distance, for example, arranged at equal intervals, so that the layout of the pictures is reasonable. In this case, a ruler is generally used to measure, mark points, thereby forming the required marks, and then the picture can be hung at the marks. Such an operation is inconvenient and time-consuming.

In one embodiment, the light selection module is a liquid crystal panel. In one embodiment, the liquid crystal panel is rectangular. In one embodiment, the laser generation module comprises a laser for generating a laser beam and a laser switch for controlling the laser to work.
