Furthermore, a pair of opposite sides of the base are respectively and correspondingly provided with two mounting holes for realizing the fixed mounting of the base.

Further, the window frame is formed by integrally molding or assembling the top cover, the connecting beam and the base.

Furthermore, the connecting beam, the top cover and the base are in a certain inclined configuration or a certain vertical configuration.

The utility model also discloses a 360 laser demarcation appearance, its laser light-emitting department disposes above-mentioned window frame structure.

After the technical scheme is adopted, compared with the prior art, the method has the following beneficial effects:

1. effectively reducing the blocking area of the connecting beam to the light emitted by the light emitting tube, and obviously reducing the broken part of the laser line.

2. The window frame structure is optimized on the basis of the existing window frame structure, and is low in cost and convenient to install.
