Background technique
Electric drill is common a kind of electronic machining tool during ongoing operations, can be divided into electric hand drill, impact drill, hammer drill three
Seed type, its working principle is that the rotor of electromagnetic rotation or electromagnetic reciprocating small capacity motor does magnetic field intercepts acting
Operating drives apparatus for work by transmission mechanism, the power of drill bit is increased with moving gear, thus make drill bit scraping material surface,
Preferably pierce object.
Currently, electric drill is widely used in the reinforcing of building girder, plate, column, wall etc., finishing, wall peace in building with industrial circle
In the installation exercises such as dress, bracket, railing, billboard, air-conditioner outdoor unit, guide rail, satellite receiver elevator, steel-structure factory building,
Suitable for the fields such as medicine, drilling at the sea and daily life.And, it is expected that in following ten to 15 years, world's electric tool pin
Volume is sold by the speed growth by annual 5%.Electric tool is a kind of " easy-consumed goods of low value ", and in European and American areas, electric tool is not only
As a kind of tool, and by as a kind of gift, become mutual gift, thus electric drill has biggish market development
Potentiality.
There is also some other deficiencies for electric drill in the prior art, such as drill bit in addition to rotary motion is few forward
Feed motion, and the depth to drill can only be judged by range estimation experience, it can not when boring the identical hole of multiple depth requirements
It accurately controls；And drill bit is mostly exposed has some potential safety problems outside in existing electric drill technology, and when pair for needing to drill
When as materials such as wooden or gypsum, many fugitive dusts can be generated, also have certain harm to the health of constructor.
