The junction of the flat channels 122 is used to divide the collimated light beam 2 emitted by the light source assembly 3 into a transmitted light beam 21 directed toward the top of the vertical channel and a reflected light beam 22 directed toward the outer end of the horizontal channel 122. The top of the vertical channel and the outer end of the horizontal channel 122 are respectively provided with conical mirror assemblies.

The conical mirror assembly at the outer end of the horizontal channel 122 is located in the direction of the reflected light beam 22 and is used to form a 360° vertical plane light curtain 7.

[0028] like Figure 3 , 5 As shown in Figures 6 and 7, the collimated light beam 2 generated by the light source assembly 3 of the utility model is divided into a transmitted light beam 21 and a reflected light beam 22 by a beam splitter 4, and passes through a vertical channel and a horizontal channel 122 which are perpendicular to each other, and then passes through a conical mirror assembly at the top of the vertical channel and the outer end of the horizontal channel 122 to form a mutually orthogonal 360° horizontal plane light curtain 6 and a 360° vertical plane light curtain 7, thereby forming two mutually perpendicular lines with an angle of 360°, which can form a 360° large-angle cross line on the surface of the building, meeting the use of large-area working conditions, and when a conical mirror assembly is used alone, the functions of a 360° ring line laser and a straight line laser can be realized, realizing multi-functional use.

[0029] Specifically, the conical mirror assembly includes a conical mirror 51 and a transparent tube 52 . The two transparent tubes 52 are respectively connected to the top of the vertical channel and the outer end of the horizontal channel 122 , and the two conical mirrors 51 are respectively connected to the ends of the two transparent tubes 52 .

The upper mounting seat 11 is provided with an upper vertical channel 111, and the lower mounting seat 12 is provided with a lower vertical channel 121 and a horizontal channel 122. One end of the horizontal channel 122 is vertically connected to the lower vertical channel 121.

The bottom surface of the upper mounting seat 11 is a 45° inclined surface. The beam splitter 4 is attached to the bottom surface of the upper mounting seat 11. The top of the lower mounting seat 12 is provided with three lower threaded holes 123 in a circular shape with equal spacing. The upper mounting seat 11 is provided with three upper threaded holes 112 corresponding to the lower threaded holes 123. The three lower threaded holes 123 correspond to the three upper threaded holes 112 in a one-to-one manner and are connected by bolts 13 respectively.

[0031] Furthermore, the conical mirror 51, the transparent tube 52, and the mounting seat are bonded to each other by an adhesive. When in use, the positions of the transparent tube 52 and the conical mirror 51 can be adjusted to ensure that the transmitted light beam 21 and the reflected light beam 22 are aligned with the tip of the conical mirror 51 at the top of the vertical channel and the outer end of the horizontal channel 122, respectively, and then bonded to each other by an adhesive.

[0033] Furthermore, the upper mounting seat 11, the lower mounting seat 12 and the bolt 13 are bonded to each other by an adhesive. When the beam splitter 4 is adjusted so that the transmitted light beam 21 and the reflected light beam 22 passing through it are just aligned with the tip of the conical mirror 51, the upper mounting seat 11, the lower mounting seat 12 and the bolt 13 are fixed by glue to ensure the accuracy of the light source.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
