Abstract
The utility model discloses an electric hand drill which is characterized in that a handle is arranged on one end of the drill body of the electric hand drill, when a hole is drilled, the handle gripped by one hand directly applies the force in the axial direction of the electric hand drill, and thus, the problems of eccentricity of applying the force of the handle of an electric pistol drill can be avoided. The other characteristic of the electric hand drill is that a vertical frame is used, so that the verticality of drilling is guaranteed.
Description
The utility model relates to a kind of punching apparatus, a kind of electric hand drill of more specifically saying so.
The applied electric hand drill of people is mainly combined by shell, motor, gear, dop each several part at present, its shell is designed to pistol type, because handle is eccentric, people are when holding handle and firmly hole, for the drill bit axial application of force also is eccentric, it is inhomogeneous that generation acts on the power of drill bit, the drill bit that fractures easily, the electric drill of this form perpendicularity for working face that can't guarantee to hole in addition.
Task of the present utility model provides a kind of electric hand drill, and it can make the outer active force basis equalization that puts on the drill bit, and has solved the perpendicularity problem of boring for working face.
In order to solve above-mentioned task, solution of the present utility model is, changing pistol grip is the axial symmetrical handle of electric drill, and this handle is installed in the end that electric drill bores body, the electric drill that power is little can simply not wanted handle yet, directly holds the electric drill shell and carries out boring work.For the perpendicularity that guarantees to hole for working face, also overlapped a vertical rack on one's body at the brill that bores, this trepanning above vertical rack is strict vertical with the other end of vertical rack, electric drill bores and can move axially in the vertical rack trepanning, like this when punching, one end face of vertical rack is close on the working face, holds the boring of electric drill handle, and the hole is just vertical naturally.
Owing to adopted the axial end mounting knob of electric drill in the above-mentioned solution, thereby when making the electric drill punching, act on the external force basis equalization on the drill bit, and the processing of this handle is simpler than pistol-like.Owing to adopted vertical rack, solved the boring perpendicularity problem that common electric hand drill cann't be solved.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A vertical view of Fig. 1.
In Fig. 1, handle 1 is installed in the end that electric hand drill bores body 3, and near being carved with one section reticulate pattern 2 in handle 1 place, the remainder that bores body 3 is set in the trepanning 8 of vertical rack 4 on brill body 3, and during electric drill work in the future, drill bit just is installed on the dop 7 that is arranged in vertical rack.For the bore position of observing drill bit and water inject cooling liquid, done 10 rectangular through holes 5 on vertical rack 4 circumferential wall, the end face of base 6 is strict vertical with trepanning 8.
Claims (1)
1, a kind of electric hand drill of being made up of shell, motor, gear, dop is characterized in that: the handle of electric hand drill is installed in the axial end of electric drill, at brill vertical rack is housed also on one's body.
