The concentrated light emitted by the light source and the electric drill bit form a certain angle. The light source capable of emitting concentrated light is disposed on the electric drill body, so that drilling depth of the electric drill is controlled according to motion of a spot of the light on a machining surface during use of the electric drill.
Description
Technical field
The present invention 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 also is 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 present invention is directed to the prior art deficiency, a kind of electric drill severity control structure is provided, 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 present invention is solved by following technical proposals:
A kind of electric drill severity control structure comprises the electric drill body, is provided with drill bit on the described electric drill body, is provided with the light source that can send convection light on the described electric drill body, and the convection light that described light source penetrates and described drill bit are at an angle.
In the 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 the technique scheme, described light source and described electric drill body are rotationally connected, be provided with pointer on the described light source, be provided with index dial on the 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, so that the angle that convection light and drill bit are can be regulated, more useful for the drilling operation of the higher precision of needs like this, accuracy requirement is higher just more to tune up the angle that convection light and drill bit are like this.
In the technique scheme, preferably, on the 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, like this so that electric drill sometimes can be used as the ruler use.
The present invention compared with prior art has following beneficial effect:
The present invention is provided with the light source that can send convection light at the electric drill body, so that electric drill can be controlled the degree of depth that electric drill pierces according to the movement that light beam is mapped to the point on the machined surface in use.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail:
Referring to Fig. 1, embodiment one, a kind of electric drill severity control structure comprises electric drill body 1, is provided with drill bit 2 on the described electric drill body 1, be provided with the light source 3 that can send convection light on the described electric drill body 1, the convection light that described light source 3 penetrates and described drill bit 2 at an angle, in the present embodiment, the convection light that described light source 3 penetrates and described drill bit 2 are 45 and spend, since 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 the described electric drill body 1, be provided with the light source 3 that can send convection light on the described electric drill body 1, described light source 3 is rotationally connected with described electric drill body 1, be provided with pointer 4 on the described light source 3, be provided with index dial 5 on the 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, like this so that the angle that convection light and drill bit 2 are can regulate, more useful for the drilling operation of the higher precision of needs like this, accuracy requirement is higher just more to tune up the angle that convection light and drill bit 2 are, on the described index dial 5 also mark have length, 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, like this so that electric drill sometimes can be used as the ruler use.
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 the wall moves is y, then the degree of depth that pierces of drill bit 2 is cotx * y, be marked with length so that drill bit 2 can directly be read from index dial 5 to the distance of hot spot at index dial 5 subscripts, use convenient.
Above-described embodiment all can be used for boring the operation of big hole, determine a bit at 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 embodiment two described a kind of electric drill severity control structures, 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
