[0029] A connecting mechanism 7 for facilitating the later disassembly and maintenance of the device by workers is installed on the outside of the laser main body 1. One end of the connecting mechanism 7 is installed with a beam expanding structure 4 for diffusing the emitted light beam. Adjusting mechanisms 9 for adjusting the laser emission position of the laser main body 1 are installed at both ends of the bottom of the laser main body 1;

[0030] Specifically, the connecting mechanism 7 includes a housing 701, a bottom plate 702, a spring block 703, and a fixing seat 704.

[0031] Specifically, as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 shown, the connecting mechanism 7 is used to protect the laser main body 1, facilitate the later disassembly of the device by workers, and maintain the laser main body 1. By clamping the housing 701 on the top of the bottom plate 702, the fixing seat 704 will be located inside the bottom plate 702, and the spring block 703 will be clamped inside the fixing seat 704. Then, the housing 701 can be fixedly installed on the top of the bottom plate 702. When the worker pulls the spring block 703 and one end of the spring block 703 moves out of the inside of the fixing seat 704, the housing 701 can be removed from the top of the bottom plate 702, and then the laser main body 1 can be maintained, thus facilitating the operation of personnel. The adjusting mechanism 9 is used to adjust the laser emission position of the laser main body 1.

[0032] In this embodiment, the adjusting mechanism 9 is installed at both ends of the bottom of the laser main body 1 for adjusting the laser emission position of the laser main body 1. Specifically, the adjusting mechanism 9 includes a boss 901, a connecting seat 902, a sleeve 903, and a screw 904. Screws 904 are installed at both ends of the bottom of the laser main body 1.

[0033] Specifically, as Figure 1As shown in the figure, in order to adjust the position where the laser of the laser main body 1 is emitted, so that the operator can emit the laser at a specified position according to the actual use situation, the bosses 901 are arranged at both ends of the bottom of the bottom plate 702. The bosses 901 and the connecting seat 902 are rotatably connected by bolts. By rotating the laser main body 1, the bosses 901 can rotate inside the connecting seat 902, so that the left - right adjustment of the laser emission angle of the laser main body 1 can be carried out. The sleeve 903 is relatively horizontally rotatably arranged at the bottom of the connecting seat 902, and the sleeve 903 and the screw 904 are connected by threads. The operator can make the sleeve 903 move up and down outside the screw 904 by rotating the sleeve 903, so that the up - down use position of the laser main body 1 can be adjusted, and the laser is emitted at the specified position.

[0034] In this embodiment, the beam expanding structure 4 is installed at one end of the connecting mechanism 7 and is used to expand the beam emitted by the laser main body 1.

The small lens 404 is fixedly installed on the inner side main body of the beam combining and expanding lens seat 401 by threads. The large lens 403 is installed at the front end of the outside of the expanding adjustment seat 402, and the large lens 403 is fixedly installed on the outside of the expanding adjustment seat 402 by threads. The laser emitted from the light - emitting port of the laser main body 1 passes through the small lens 404 and the large lens 403 to achieve the cylindrical collimation and expansion of the beam.

[0036] Further, four groups of support columns 8 are installed on the top of the bottom plate 702.

[0037] Specifically, as Figure 2 shown, in order to support the laser device chip 101 at the top, the top of the support column 8 is connected to the laser device chip 101, and the support column 8 can raise the laser device chip 101 and play a supporting role for it.

[0038] Further, radiators 2 are installed on both sides of the laser device chip 101, and DC fans 3 are installed on both sides of the housing 701.

[0040] Furthermore, an optical output hole 5 is provided at one end of the housing 701, and a signal interface 6 is provided at the end of the housing 701 away from the optical output hole 5;

[0041] Specifically, as Figure 2 shown, in order to enable the laser main body 1 to work properly, by connecting the signal interface 6 to wires and data lines, it is used for power supply connection and signal control of the laser main body 1. The laser emitted by the laser main body 1 will be emitted through the optical output hole 5 into the internal of the beam expander structure 4 for cylindrical collimation and beam expansion.

[0042] Working principle: By clamping the housing 701 on the top of the bottom plate 702, the fixing seat 704 will be located inside the bottom plate 702, and the spring block 703 will be clamped inside the fixing seat 704. Then the housing 701 can be fixedly installed on the top of the bottom plate 702. At this time, through the control of the RF component 102 to provide RF energy, the laser diode chip 101 emits laser light. The laser light emitted from the light output port of the laser main body 1 passes through the small lens 404 and the large lens 403 to achieve cylindrical collimation and beam expansion of the light beam.
