[0045] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a fixing ring 11, a connecting block 12 and a fixing bolt 13.

When the fan 26 is running, it will blow air downward, thereby increasing the gas flow rate inside the heat dissipation block 24, increasing the heat dissipation efficiency, and thus having a cooling effect on the focusing cavity plate 5.

[0068] The working principle and use process of the present invention:

[0069] First, the operator can put the laser generator 3 into the shell 1 and make it located above the mounting block 2. Then the operator can pass the fixing bolt 17 through the inside of the laser generator 3 and screw it into the inside of the mounting block 2 to fix the laser generator 3. After that, the operator can make the two clamping plates 8 enter the inside of the two notches 7 respectively. At this time, the connecting block 12 will be located inside the fixing ring 11. The operator can extend the right end of the focusing cavity plate 5 into the inside of the shell 1 and put the copper sheet 22 on the outside of the focusing cavity plate 5, and finally make the clamping block 6 enter the inside of the laser generator 3.

[0070] Then, the operator can use the fixing bolt 13 to pass through the interior of the fixing ring 11 and screw it into the interior of the shell 1 to fix the two focusing cavity plates 5 through the fixing ring 11. Then the operator can cover the cover 18 so that the heat sink 24 is located inside the cover 18. The operator can use the mounting bolt 20 to pass through the interior of the cover 18 and screw it into the interior of the fixing block 19 to fix the cover 18. After that, the operator can place the fan 26 above the heat sink 24, use the mounting bolt 27 to pass through the interior of the laser lens 16 and screw it into the interior of the positioning block 15 to fix the fan 26. When the fan 26 is running, the gas flow rate inside the heat sink 24 can be increased, thereby dissipating the heat of the focusing cavity plate 5 through the copper sheet 22 and the heat conductive block 23.
