In the shelf of electric drill described above, the structure of jack-up electric drill as shown in Figure 3, in the process of top offset, electric drill can depart from simultaneously the displacement of d to horizontal direction at the jack-up electric drill.Cause the hole that gets out on ceiling to be bar shaped, do not utilize bolt or screw fixing in through hole.And in the words that the installation of some light fixture is fixed, need to get out on the ceiling end face and have and end face inclined hole at an angle, to with electric drill stand in above-mentioned patent is open, if in the time of need to getting out the inclined hole with certain angle on the ceiling end face, can't realize.Therefore be necessary to improve.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the inclined hole that can get out the special angle of actual needs on ceiling.
The utility model is achieved through the following technical solutions: perforating device, comprise base, rotate on described base and be provided with guide pin bushing, described base is positioned at and is provided with the angle scale of measuring the guide pin bushing rotational angle on the position of described guide pin bushing one side and slides at described guide pin bushing and be provided with guide pillar, be provided with tooth bar on described guide pillar outer wall, be provided with the gear that is mated on described tooth bar, described gear is connected with rotating shaft, be provided with in the end of described guide pillar for the fixing electric drill fixed mount of electric drill, be fixed with electric drill on described electric drill fixed mount.
In technique scheme, the lower surface of described base is provided with roller.
In technique scheme, described guide pillar comprises cylinder and sleeve pipe, and described cylinder slides and is arranged in described sleeve pipe, offers screwed hole on described column side wall, and cylinder is established bolt and is fixed in sleeve pipe by twisting in screwed hole.
In technique scheme, be provided with light source on described electric drill.
The utility model compared with prior art has following beneficial effect: can get out the inclined hole of special angle on ceiling, and simple in structure, use very convenient.

The specific embodiment
below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 2 to Fig. 3, perforating device, comprise base 101, rotate on described base 101 lead 2 is set, and described base 101 is positioned at and is provided with the angle scale 4 of measuring lead 2 rotational angles on the position of described guide pin bushing one side, sheathed sliding sleeve 3 on described lead 2, sliding sleeve 3 and connecting rod 30 1 ends are rotationally connected, described connecting rod 30 other ends and a depression bar 31 are rotationally connected, described depression bar 31 be rotationally connected with described lead 2 on, driving sliding sleeve 3 by lower moulded rod 31 slides up and down at lead 2.
Described sliding sleeve 3 one sides are fixedly installed and are useful on the fixedly electric drill fixed mount 8 of electric drill, during use, fixing electric drill 7 on described electric drill fixed mount 8, namely, when pressing depression bar 31, drive the electric drill upper and lower displacement, so electric drill 7 can in the displacement of its moving direction generation horizontal direction, not guarantee the precision of electric drill boring.
At described electric drill 7 end positions, light source 5 is set, 5 light of establishing of light source have the position as Fig. 4, be that light source 5 emission of lights are by the top marginal position of electric drill and stretch out, during use, the position that light source 5 shines namely think electric drill 7 in the position of punching on ceiling (although have error on certain precision, but this error is very little, therefore can ignore), solved in the higher problem of determining that with the naked eye punch position easily produces deviation and the drill bit punching is located when sky blackboard glazed thread is more dim of sky blackboard.
The lower surface of described base 101 is provided with roller 6, is convenient to adjust in use the position of base.
During use, at first rotate lead 2 and arrive then fixed guide post of needed angle position, then adjust lower moulded rod, holing gets final product to the position (this position can be confirmed by the position that light source 5 shines) that needs punching to make electric drill.
Referring to Fig. 5, described electric drill 7 comprises handle 73, at an end of described handle 73, battery 72 is housed, and has the motor 75 that drives drill bit in described electric drill 71, and described motor 75 comprises output shaft 750.
Also comprise body 78, be full of cooling water in described body 78, described body 78 forms the closed-loop path around motor 75 and in described electric drill 7, body 78 is provided with magnetic drives wheel 74 near described output shaft 750 inside, position, described output shaft 750 is fixedly installed permanent magnet 77 near a side of described magnetic drives wheel 74, when electric drill uses, motor output shaft 750 rotates the rotation that drives permanent magnet 77, drive the rotation of magnetic drives wheel 74 by the mode of magnetic transmission, thereby make the cooling water in body 78 to circulate.
Be provided with in described electric drill 7 for the storage tank 76 that stores cooling water, in described storage tank 76, more cooling water is set, described storage tank 76 and described body 78 are communicated with, so just can have enough cooling waters and absorb the heat that battery produces in the electric drill running, guarantee that the cooling water heat absorption is too much ineffective after the electric drill long-play.
Be provided with through hole 760 on described storage tank 76, electric drill 7 can be dismantled corresponding to the housing of through hole 760 positions, twist to be provided with on described through hole 760 and twist cap 761, in the long-time use procedure of electric drill, if need to increase or change cooling water in body 78, only need dismounting electric drill 7 corresponding to the housing of through hole 760 positions, turn on cap 761, add or pour out cooling water to get final product in through hole 760.
