[0007] Based on the above technical features, further, a plurality of limiting protrusions are provided on the inner wall of the connecting ring in a circumferential direction, and the limiting protrusions cooperate with the limiting holes of the connecting sleeve for limiting and fixing.

[0008] Based on the above technical features, further, the fixed protective cover and the retractable protective cover are both made of transparent materials, so that the user can clearly observe the working area of ​​the drill bit and discover abnormal situations in time during the work process.

[0009] Based on the above technical features, preferably, a quick connection mechanism is further provided between the fixed protective cover and the retractable protective cover, and the user can quickly install or remove the retractable protective cover by operating the quick connection mechanism to flexibly adapt to different work scenarios and needs.

[0010] Based on the above technical features, preferably, the angle adjustment assembly also includes a thread adjustment structure, and the thread adjustment structure is located at the rear end of the connecting sleeve, and the user can adjust the length of the connecting sleeve by rotating the thread adjustment structure.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] By adjusting the angle of the protective cover, users can better control the coverage of the protective cover, effectively preventing debris or splashes from hitting hands or other parts of the body. The adaptable protective cover angle design helps improve work safety and reduce the risk of accidental injury;

[0013] The quick connection mechanism design allows users to quickly install or remove the retractable protective cover, reducing tool and time costs and improving work efficiency. Users can easily replace the protective cover according to actual needs to meet the needs of different work scenarios, enhancing the practicality and convenience of the product.
