Description
Technical field
The utility model relates to electric drill, in particular to one kind drills through accurately electric drill.
Background technique
Electric hand drill is tool relatively common in daily life.Such as the China that Granted publication is well CN202824745U
Patent " a kind of band double handle electric drill ", including electric drill body, the electric drill body are connected with drill bit and storeroom, and drill bit is mounted on electric drill
The tail portion of electric drill body is arranged in the head of body, storeroom, it is characterised in that: the electric drill body is equipped with two handles, is located at
The upper and lower part of electric drill body tail portion.It is equipped with switch on the handle, and switchs and is coated with layer of fluorescent powder.
Disadvantage is that electric drill needs for electric drill to be aligned with drilling through before drilling through to the face of drilling through, and above-mentioned electric drill is set
Two handles are equipped with, when mobile electric drill alignment drills through, alignment is inconvenient, more even on alignment vertical plane or inclined surface
When drilling through, be aligned worse for efficiency and the more existing single-grip electric drill of result, cause to drill through precision decline, bore
Partially, askew phenomenon is bored, therefore is had much room for improvement.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind to drill through accurately electric drill, it is right
Shell and with shell is mobile and the position of the drill bit of rotation is adjusted, angular adjustment is more accurate, raising drills through accuracy.
The above-mentioned technical purpose of the utility model has the technical scheme that
One kind drilling through accurately electric drill, including shell, drill bit, the first handle and the second handle, the drill bit are installed on shell
One end of body, first handle and the second handle are connected and fixed on the lateral surface of shell, the length direction of second handle
It is axially vertical with drill bit, and the length direction of the length direction and the first handle of second handle is perpendicular.
By using above-mentioned technical proposal, electric drill in use, two hand of user difference the first handle of handle and the second handle,
Due to the length direction while the length direction of vertical first handle and the axial direction of drill bit of the second handle, drilled through by drill bit alignment
Behind face, manpower by the first handle and the second handle shell two can be drilled through in parallel face two power and two power it is perpendicular, therefore
To shell and with shell is mobile and the position of the drill bit of rotation is adjusted, angular adjustment is more accurate, raising drills through accuracy.
The utility model is further arranged to: the hull outside face is set in the second symmetrical other side in handle junction
It is equipped with limiting slot, second handle includes holding column, fixed thread column and fixture nut, the fixture nut to be connected to limit
