Description

technical field [0001] The invention relates to the field of electric tools, in particular to a portable household electric drill. Background technique [0002] Electric drill is a drilling tool powered by electricity. It is a conventional product in electric tools and is also the most demanded electric tool product. Electric drill products are suitable for drilling holes in steel, wood and plastic, and are the most used among hand-held electric tools. One of the most popular tools, the electric drill is the most commonly used electric tool. It has the advantages of convenience, low price, and portability, and is well received by workers in the hardware and decoration industries; [0003] Due to the ventilation and heat dissipation of the electric drill, there is a lot of dust inside after long-term use.

Problems solved by technology

[0003] Due to the ventilation and heat dissipation of the electric drill, there is a lot of dust inside after long-term use. The dust will mix and deteriorate the lubricating oil on the gears and bearings and dry up, which will aggravate wear and tear, especially if it is used in an alternative way. There is an excessively large gap, so it is extremely necessary to keep the interior clean. At the same time, due to the large amount of dust generated during work, the cleaning work is difficult to complete. At the same time, although the staff will wear a protective cover to work, it will affect the surrounding environment. Dust and Debris will fly randomly, causing serious pollution;

[0004] When using an electric drill, it is often necessary to replace the drill bit. Because of the convenience, the operator directly replaces the drill bit when the electric drill is not powered off. If you or someone else accidentally touches the switch when changing the drill bit, it is very dangerous. At present, when the household electric drills used in the market need to drill to the top, the electric drill body can only be turned upwards. On the one hand, it affects the accuracy, on the other hand, there is no guarantee for the safety of the staff, it is inconvenient to use, and there are some problems in positioning during the work process. lacking
