[0028] See also Figure 1 and Figure 3 , a switching mechanism 5, which is located between the galvanometer lens 2 and the reflector 4 and is used to quickly switch between laser alignment cutting and galvanometer scanning cutting. The switching mechanism 5 includes a driving mechanism and a connecting mechanism. The connecting mechanism is located between the reflector 4 and the driving mechanism and is used to connect the reflector 4. The driving mechanism is located on one side of the galvanometer lens 2 and is used to drive the reflector 4 to move. The connecting mechanism includes a mounting block 56 fixed to the top of the reflector 4 and a first slider 55 fixed to one side of the galvanometer lens 2. A linkage plate is fixed to one side of the mounting block 56, a block matching the first slider 55 is fixed to one side of the linkage plate, and a moving plate 54 is fixed to one side of the linkage plate.

[0031] When in use, pulling the control plate drives the plug plate 62 to move, and the movement of the plug plate 62 drives the moving block 64 to move, and the movement of the moving block 64 drives the spring 63 to contract. At the same time, the setting of the limit rod makes the moving block 64 more stable when moving, and the contraction of the spring 63 makes the plug plate 62 separate from the slot. After the plug plate 62 and the slot are separated from each other, the linkage plate is pulled to drive the disassembly block 65 to move, until the disassembly block 65 is moved to be separated from the moving plate 54, the reflector 4 can be disassembled, thereby facilitating the user to maintain and repair it.
