The light source capable of emitting the centralized light beam is arranged on the electric drill body, so that an electric drill in use can control drilling depth according to moving of a point, on a processing face, irradiated by the light beam.
Description
Technical field
The utility model relates to a kind of electric tool, specifically a kind of electric drill severity control structure.
Background technology
Electric drill is a kind of electric tool commonly used, it is also the electric tool series products that has the call, the electric drill operation principle is that the rotor of electromagnetic rotating formula or electromagnetic reciprocating low capacity motor is done magnetic field intercepts acting running, drive apparatus for work by transmission mechanism, driven gear strengthens the power of drill bit, thereby make drill bit scrapings surface, better pierce object.Traditional electric drill does not generally all have the allocating and measuring electric drill to pierce the instrument of the degree of depth, so the degree of depth that drill bit pierces is difficult to control, and perhaps for example when needing to bore the identical hole of row's spacing, traditional electric drill needs underlining, and operation also comparatively bothers.
Summary of the invention
The utility model is not enough for prior art, and a kind of electric drill severity control structure is provided, and this kind electric drill severity control structure can conveniently be controlled the degree of depth that electric drill pierces, and can improve precision, even can work as chi and use.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of electric drill severity control structure, comprise the electric drill body, be provided with drill bit on described electric drill body, be provided with the light source that can send convection light on described electric drill body, the convection light that described light source penetrates and described drill bit are at an angle.
In technique scheme, preferred, the convection light that described light source penetrates and described drill bit are 45 degree, because tan45 °=1, the distance of the movement of the length that electric drill pierces and convection light point on the wall.
In technique scheme, described light source and described electric drill body are rotationally connected, be provided with pointer on described light source, be provided with index dial on described electric drill body, described index dial subscript is marked with described light source and penetrates the angle that convection light and described drill bit are, make like this angle that convection light and drill bit are to regulate, more useful for the drilling operation of the higher precision of needs like this, accuracy requirement is higher just more tunes up the angle that convection light and drill bit are.
In technique scheme, preferably, on described index dial also mark have length, described length be described drill bit end points when vertically touching a plane convection light be mapped to point on the plane to the distance of described drill bit end points, make like this electric drill sometimes can be used as ruler and use.
The utility model compared with prior art, have following beneficial effect: the utility model is provided with the light source that can send convection light on the electric drill body, makes electric drill can control the degree of depth that electric drill pierces according to the movement that light beam is mapped to the point on machined surface in use.

Fig. 2 is the structural representation of the utility model embodiment two.
Fig. 3 is the structural representation of the electric drill that adopts of the utility model.
The specific embodiment
below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1, embodiment one, a kind of electric drill severity control structure, comprise electric drill body 1, be provided with drill bit 2 on described electric drill body 1, be provided with the light source 3 that can send convection light on described electric drill body 1, the convection light that described light source 3 penetrates and described drill bit 2 are at an angle, in the present embodiment, convection light and described drill bit 2 that described light source 3 penetrates are 45 degree, because tan45 °=1, the distance of the movement of the length that electric drill pierces and convection light point on the wall.
Embodiment one in use, drill bit 2 vertically pierces the plane, the displacement of the hot spot that convection light when piercing according to drill bit 2 on the plane forms is controlled the degree of depth that electric drill pierces.
referring to Fig. 2, embodiment two, a kind of electric drill severity control structure, comprise electric drill body 1, be provided with drill bit 2 on described electric drill body 1, be provided with the light source 3 that can send convection light on described electric drill body 1, described light source 3 is rotationally connected with described electric drill body 1, be provided with pointer 4 on described light source 3, be provided with index dial 5 on described electric drill body 1, described index dial 5 subscripts are marked with described light source 3 and penetrate the angle that convection lights and described drill bit 2 are, the angle that makes like this convection light and drill bit 2 be can be regulated, more useful for the drilling operation of the higher precision of needs like this, accuracy requirement is higher just more tunes up the angle that convection light and drill bit 2 are, also mark on described index dial 5 length is arranged, described length be described drill bit 2 end points when vertically touching a plane convection light be mapped to point on the plane to the distance of described drill bit 2 end points, making like this electric drill sometimes can be used as ruler uses.
Embodiment two in use, regulating the convection light of described light source 3 ejaculations and the angle of drill bit 2 formation is x, drill bit 2 vertically pierces the plane, the displacement of the hot spot that the convection light when piercing according to drill bit 2 on the plane forms is controlled the degree of depth that electric drill pierces, the distance that hot spot on wall moves is y, the degree of depth that pierces of drill bit 2 is cotx * y, be marked with length at index dial 5 subscripts and make drill bit 2 can directly read from index dial 5 to the distance of hot spot, use convenient.
Above-described embodiment all can be used for boring the operation of big hole, determine a bit on the face that will hole, then electric drill rotates around this point, to guarantee simultaneously drill bit 2 all the time and convection light vertical with this face be radiated at all the time on definite point, can get out a great circle.
In above-described embodiment one and the described a kind of electric drill severity control structure of embodiment two, referring to accompanying drawing 3, comprise handle 6, at an end of described handle 6, battery 12 is housed, have the motor 7 that drives drill bit 2 in described electric drill body 1, described motor 7 comprises output shaft 70
