[0002] An electric drill is a drilling machine that uses electricity as power. It is a conventional product among power tools and also the most in-demand power tool product. Its annual production and sales volume accounts for 35% of China's power tools. The main specifications of electric drills are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49 mm, etc. The number refers to the maximum diameter of the drill bit for drilling holes on steel with a tensile strength of 390N / mm2. The maximum drilling diameter for non-ferrous metals, plastics and other materials can be 30 to 5 larger than the original specifications.

[0003] The existing Chinese patent with announcement number CN216176864U discloses a handheld electric drill drilling device for engineering construction, including a handheld electric drill body, a drill bit is arranged at the output end of the handheld electric drill body, and a mounting hoop is arranged at the mounting end of the handheld electric drill body close to the drill bit, the mounting hoop is arranged in a ring shape, and a mounting ring is arranged at the inner wall of one side of the mounting hoop close to the drill bit, an elastic protective sleeve is arranged at the side wall of the mounting ring away from the mounting hoop, the elastic protective sleeve is sleeved on the outer ring of the drill bit, and the end of the elastic protective sleeve away from the mounting ring is aligned with the end of the drill bit away from the handheld electric drill body, a dust reduction mechanism is arranged at the inner side wall of the end of the elastic protective sleeve close to the drill bit, and a sound insulation sleeve is arranged at the outer ring of the elastic protective sleeve. The application facilitates avoiding the overflow of debris and dust during the drilling operation, reduces pollution to the environment, and is conducive to improving the environmental protection effect.
