Description
Technical field
The utility model belongs to electrical appliances field, especially a kind of electric hand drill with refrigerating function.
Background technology
At present, existing electric hand drill relies primarily on metal bit rotation, cutting metal pore-forming, however long period high speed is revolved
The change of team generates high temperature, causes metal bit discoloration annealing, and badly damaged cutter reduces the service life.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of simple and reliable, scope of application
The extensive electric hand drill for carrying refrigerating function.
The utility model solves its technical problem and following technical scheme is taken to realize：
A kind of electric hand drill with refrigerating function is equipped with a rotation axis, the rotation in the output terminal driving of electric hand drill main body
Axial one end of shaft is coaxially fixed with a drill bit deck, and drill bit deck, which is coaxially mounted, a metal bit, and feature exists
In：Rotation axis periphery between drill bit deck and electric hand drill main body is fixed with multiple fan blade, the plurality of fan blade
Angle of inclination is identical, and air-flow is oriented to the direction of metal bit.
Moreover, the electric hand drill body end in fan blade periphery is fixed with a protective cover.
Moreover, radial equipartition is formed with multiple air inlet holes on protective cover, protective cover towards the one side of metal bit be open ports
Structure.
Moreover, the structure of the main body of the drill bit deck for one with rotating shaft coaxle to circular cone structure, towards fan
One end of blade is outsole, is handle towards one end of metal bit；Drill bit card slot coaxially is formed in the middle part of drill bit deck, in drill bit
The air-guiding hole of multiple perforation outsoles and handle is formed in the drill bit deck of card slot periphery.
The advantages of the utility model and good effect are：
The utility model drives in the rotation axis of electric drill and is equipped with fan leaf, is carried out in Drilling operation with to metal bit
It constantly cools, extends the service life of metal bit, and can apply in the field of similar working method, be applicable in
Property is wide.
Description of the drawings
Fig. 1 is the structural front view (broken section) of the utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of electric hand drill with refrigerating function, referring to shown in attached drawing, the present embodiment is gun-type electric hand drill, in electric hand drill master
The output terminal driving of body 6 is equipped with a rotation axis 4, and axial one end of the rotation axis is coaxially fixed with a drill bit deck 2, drill chuck
Coaxial be mounted of seat has a metal bit 1, and the innovative point of the utility model is：
Rotation axis outer periphery between drill bit deck and electric hand drill main body is uniformly equipped with multiple fan blade 3, this
Fan blade shown in embodiment is six, and the angle of inclination of the plurality of fan blade is identical, and air-flow is oriented to metal bit
Direction.
Safe to use in order to ensure, the electric hand drill body end in fan blade periphery is fixed with a protective cover 5, protective cover
Upper radial equipartition is formed with multiple air inlet holes 7, and protective cover is to open wide mouth structure towards the one side of metal bit, ensures that air-flow smoothly flows
It is dynamic.
The structure of the main body of drill bit deck for one with rotating shaft coaxle to circular cone structure, towards one end of fan blade
It is handle towards one end of metal bit for outsole；Drill bit card slot coaxially is formed in the middle part of drill bit deck, in drill bit card slot periphery
The air-guiding hole 8 of multiple perforation outsoles and handle, cooling effect of the enhancing cooling wind to metal bit are formed in drill bit deck.
Application method：
During normal use, when electric hand drill starts, metal bit rotates at a high speed simultaneously with fan leaf, fan leaf cutting air production
Anger stream, blows to drill bit, plays refrigerating function, the high temperature generated during drilling bit high-speed rotary is avoided to damage metal bit, so as to prolong
The service life of long metal bit.
Although disclosing the embodiment and attached drawing of the utility model for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modification are all can
Can, therefore, the scope of the utility model is not limited to embodiment and attached drawing disclosure of that.
