[0002] A laser is a device used to process optical fibers, and a fiber laser is a laser that uses optical fibers as a medium, and can have higher beam quality, better stability, and so on.

[0003] When a fiber laser is in use, the interface between the fiber and the optical fiber often needs to be dust-proofed to prevent the interface from being contaminated and causing loss, which would affect the fiber laser's processing of the optical fiber. Existing technology, such as a dust-proof and moisture-proof device for a semiconductor laser optical fiber interface with announcement number CN214411756U, comprises: a dust-proof seat, which is annular, and a first end of the dust-proof seat is fixedly sleeved on the boss and sealed to the boss; a dust-proof head, one end of the dust-proof head is open and the other end is closed, and the open end of the dust-proof head is detachably sealed to the second end of the dust-proof seat; the dust-proof and moisture-proof device can isolate the optical fiber interface from the outside air when the laser optical fiber interface is not connected to an optical fiber, thereby achieving sealed dust-proof treatment.

[0004] However, the utility model uses a dustproof seat and a first sealing ring to achieve dust-proof sealing of the optical fiber interface. This method may cause the first sealing ring to not be able to seal the optical fiber interface well due to inaccurate placement of the dustproof seat, and the dust-proof effect is difficult to ensure, or it may be necessary to repeatedly cover and remove the dustproof seat to ensure that the dustproof seat completely seals the optical fiber interface, making the utility model inconvenient to use. Utility Model Content

[0005] In response to the technical defects mentioned in the above background technology, the present invention proposes a high-power fiber laser and cutting head disassembly dust-proof device with sealing effect.

[0011] In one embodiment, it further includes: a rubber pad; the rubber pad is fixedly connected to the contact position between the dust cover and the inner wall of the cutting head.

[0012] The beneficial effects are:

[0013] The utility model provides a dust cover with a thread and a rotating sleeve, so that the dust cover is highly matched with the cutting head, and the dust cover can well seal the cutting head. The use of a guide block can ensure that the threads on the dust cover are aligned with the rotating sleeve of the rotating sleeve before the dust cover is connected to the rotating sleeve. At the same time, the position of the dust cover can be restricted, so that the placement position of the dust cover is more accurate, the cover can be better covered, and the sealing effect of the dust cover is improved.
