Description

Technical Field ,

[0001] The utility model relates to the technical field of impact drills, and specifically relates to a noise-reducing indoor decoration drilling machine. Background Art

[0002] An impact drill is a power tool that mainly performs rotary cutting and also has an impact force generated by the operator's thrust, and is used for drilling operations on various materials. In indoor decoration of houses, an impact drill is usually used for drilling operations in walls.

[0003] When an impact drill is in use, it needs to be pressed against the outside of the wall and a thrust is applied for drilling. However, in existing houses and home buildings, there are usually hollow materials, which may cause the impact drill to penetrate the wall during drilling operations and hit the outside of the wall, causing harm to both the user and the impact drill, thereby reducing the overall use effect.
