Problems solved by technology
[0003] The light output structure of the existing line projector often needs to be equipped with multiple laser emitters. Some laser emitters emit horizontal lines, and the other laser emitters emit vertical lines. The stability of multiple lasers is poor. As long as one laser moves Causes angular misalignment between horizontal and vertical

Abstract
The invention discloses a light emitting structure of a demarcation device, and relates to the technical field of demarcation devices. The light emitting structure comprises a pendulum bob body, a vertical line emitting channel located on one side of the pendulum bob body, a light emitting channel located in the pendulum bob body, a laser emitter located at the lower end of the light emitting channel and used for emitting laser, a glass sheet located in the light emitting channel and used for reflecting and refracting the laser, a vertical line prism positioned in the vertical line emitting channel and used for refracting the reflected laser into a vertical line, and a horizontal line prism positioned at the upper end of the light emitting channel and used for reflecting the refracted laser into a horizontal line; the included angle between the laser and the glass sheet is 45 degrees, the vertical prism is cylindrical, and the horizontal prism is conical. A laser emitter is adopted, and laser is reflected and refracted to finally form a vertical line and a horizontal line.
Description
technical field [0001] The invention belongs to the technical field of a wire casting device, and in particular relates to a light output structure of a wire casting device. Background technique [0002] At present, the line throwing instrument has been widely used in construction, decoration and other similar work to provide horizontal lines and vertical lines to achieve orientation and positioning. Commonly used line projectors are mainly composed of a light output structure and a compensation structure. [0003] The light output structure of the existing line projector often needs to be equipped with multiple laser emitters. Some laser emitters emit horizontal lines, and the other laser emitters emit vertical lines. The stability of multiple lasers is poor. As long as one laser moves Causes angular misalignment between horizontal and vertical lines. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings ...
