Description
Technical field
The invention belongs to field of power tools, and in particular to a kind of safe electric drill for being capable of fast feed.
Background technology
Electric drill is a kind of electronic machining tool commonly used during ongoing operations, can be divided into electric hand drill, impact drill, hammer drill three
Type, its operation principle is that the rotor of electromagnetic rotating formula or electromagnetic reciprocating low capacity motor does magnetic field intercepts acting
Operating, apparatus for work is driven by transmission mechanism, and the power of drill bit is increased with moving gear, so that drill bit scraping material surface,
Preferably pierce object.
At present, electric drill is widely used in the reinforcing of building girder, plate, post, wall etc., finishing, wall peace in building and industrial circle
In the installation exercises such as dress, support, railing, billboard, air-conditioner outdoor unit, guide rail, satellite receiver elevator, steel-structure factory building,
Suitable for the fields such as medical science, 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 instrument, and by as a kind of gift, as mutual gift, thus electric drill has larger market development
Potentiality.
Also there is some other deficiency in electric drill of the prior art, as drill bit except rotary motion it is few forward
Feed motion, and the depth drilled can only be judged by range estimation experience, can not when boring multiple depth requirements identical holes
Accurate control；And drill bit is mostly exposed has certain potential safety hazard outside in existing electric drill technology, and when pair for needing to drill
During as materials such as wooden or gypsum, many airborne dusts can be produced, also have certain harm to the health of constructor.
The content of the invention
