[0003] For example, the public document with application number 201920870230.1 discloses a dust-proof cutting device for circuit board processing. The utility model has a simple structure and reasonable design. It is convenient to quickly fix circuit boards of different thicknesses and sizes, ensure cutting stability, and has a dust removal function. In addition, it can quickly adjust the position of the circuit board and quickly cut the circuit board at different positions and angles. However, the dust-proof device for circuit board processing, no matter the debris and dust generated during cutting or drilling, is only blocked and protected by the cover body. The debris accumulates inside the protective cover, and the protective cover is not easy to disassemble, which is not conducive to cleaning the internal dust. This dust collection and processing process is not convenient and fast enough.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a dustproof device for circuit board processing is proposed. Utility Model Content
