Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 5, in an embodiment of the utility model, a dust collection assembly for a drilling machine includes: a hollow drill bit 20 and a dust extraction adapter 10. The dust adapter 10 is used to mount a hollow drill bit 20 to a drilling machine. The dust collection adapter 10 includes: a connecting shaft 11, a rotary sleeve 12 and a dust collection pipe 13. The connecting shaft 11 is used to connect the hollow drill bit 20 and the drilling machine. One end of the connection shaft 11 is provided with a first connection structure 111 for connecting the hollow drill bit 20. The other end of the connecting shaft 11 is provided with a second connecting structure 112 for connecting to a drilling machine. The drill bit is mounted to the connecting shaft 11.
