The present invention relates to a kind of perforating device, particularly relate to a kind of device utilizing electric hand drill to punch to ceiling.
When punching on the ceiling with electric hand drill, general operation is: the first good ladder of frame, then workman uses electric hand drill to punch to ceiling after climing up the ladder, want head to face upward due to workmen and upwards exert all one's strength, be very difficult to operation, also will stand on scaffold simultaneously or step down on ladder, when making operation, stability and security receive very large impact.
For above-mentioned defect, license notification number is " CN201924573U ", name is called " hole drilling-up auxiliary device of impact electric drill ", disclose hole drilling-up auxiliary device of impact electric drill, mainly comprise the straight-bar of scalable adjustment, a hand support is provided with below the pole of described scalable adjustment, pole top is provided with can fix impact electric drill device, hand support is connected with pole lower end by movable rod in the middle of the mobile jib of band base, the band handle ripping bar at mobile jib top is connected in the middle of pole by pivot pin, forming thus can the structure of parallel upper sled, can fix impact electric drill device is be provided with a supporting plate and several fixing latch closure at the top of pole, during use, electric impact drill is fixed on the top of pole, prop up the mobile jib with base, hand holding handle handle, press down ripping bar, the punching to top can be realized thus.
In addition, number of patent application is " 201010112742.5 ", name is called " Mobile support frame for electric drill ", also a kind of electric drill bracing frame is disclosed, mainly comprise support bar, push rod is connected with by activity operations bar above support bar, electric drill fixed mount and dust collection cover are equipped with in push rod upper end, the lower end of support bar is provided with sliding bottom, activity operations bar and push rod junction are provided with for the movable branching rod of locating and reinforce, support bar is provided with the supply socket of mobile lever and power switch or belt switch, during use, electric drill can be fixed on electric drill fixed mount, by lower by activity operations bar, can punch to the ceiling flat-top of top.
In the shelf of electric drill described above, as shown in Figure 3, at jack-up electric drill in the process of top offset, electric drill can depart from the displacement of d to the structure of jack-up electric drill simultaneously to horizontal direction.Cause the hole got out on the ceiling to be bar shaped, do not utilize bolt or screw in through-holes fixing.And in the words that the installation to some light fixture is fixing, needs get out on ceiling end face to be had and end face inclined hole at an angle, to with the electric drill stand in above-mentioned patent is open, when if desired getting out the inclined hole with certain angle on ceiling end face, then cannot realize.Therefore be necessary to improve.
Summary of the invention
For the deficiencies in the prior art, the invention provides the inclined hole that can get out the special angle of actual needs on the ceiling.
The present invention is achieved through the following technical solutions: perforating device, comprise base, described base rotates and is provided with guide pin bushing, the position that described base is positioned at described guide pin bushing side is provided with the angle scale measuring guide pin bushing rotational angle to slide at described guide pin bushing and be provided with guide pillar, described guide pillar outer wall is provided with tooth bar, described tooth bar is provided with the gear be mated, described gear is connected with rotating shaft, be provided with the electric drill fixed mount for fixing electric drill in the end of described guide pillar, described electric drill fixed mount is fixed with electric drill.
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, and described column side wall offers screwed hole, and cylinder establishes bolt to be fixed in sleeve pipe by twisting in screwed hole.
In technique scheme, described electric drill is provided with light source.
The present invention compared with prior art, has following beneficial effect: the inclined hole that can get out special angle on the ceiling, and structure is simple, uses very convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 2 to Fig. 3, perforating device, comprise base 101, described base 101 rotates lead 2 is set, and the position that described base 101 is positioned at described guide pin bushing side is provided with the angle scale 4 measuring lead 2 rotational angle, sheathed sliding sleeve 3 on described lead 2, sliding sleeve 3 and connecting rod 30 one end are rotationally connected, described connecting rod 30 other end and a depression bar 31 are rotationally connected, described depression bar 31 is rotationally connected with on described lead 2, sliding sleeve 3 is driven to slide up and down on lead 2 by lower moulded rod 31
Described sliding sleeve 3 side is fixedly installed the electric drill fixed mount 8 for fixing electric drill, during use, described electric drill fixed mount 8 fixes electric drill 7, namely, when pressing depression bar 31, drive electric drill upper and lower displacement, therefore electric drill 7 can not produce the displacement of horizontal direction at its moving direction, ensure that the precision that electric drill is holed.
At described electric drill 7 end position, light source 5 is set, light source 5 light established have the position as Fig. 4, namely light source 5 emission of light is stretched out by the top marginal position of electric drill, during use, namely the position that light source 5 is irradiated to thinks that position that electric drill 7 punches on the ceiling is (although have the error in certain precision, but this error is very little, therefore negligible), solve in the higher problem with the naked eye determining that punch position easily produces deviation and 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 the position adjusting base in use.
During use, first rotating lead 2 to required angle position then fixed guide post, then the lower moulded rod of adjustment, making electric drill carry out holing to needing the position (position that this position can be irradiated to by light source 5 confirms) of punching.
See Fig. 5, described electric drill 7 comprises handle 73, in one end of described handle 73, battery 72 is housed, and in described electric drill 7, have the motor 75 driving drill bit, described motor 75 comprises output shaft 750.
Also comprise body 78, cooling water is full of in described body 78, described body 78 is around motor 75 and form closed-loop path in described electric drill 7, body 78 is provided with magnetic drives wheel 74 near inside, described output shaft 750 position, described output shaft 750 is fixedly installed permanent magnet 77 near the side of described magnetic drives wheel 74, when electric drill uses, motor output shaft 750 rotates the rotation driving permanent magnet 77, the mode transmitted by magnetic drives magnetic drives to take turns the rotation of 74, thus the cooling water in body 78 can be circulated.
The storage tank 76 for storing cooling water is provided with in described electric drill 7, in described storage tank 76, more cooling water is set, described storage tank 76 is communicated with described body 78, so just can have the heat that enough cooling waters produce in electric drill running to absorb battery, after ensure that electric drill long-play, cooling water heat absorption is too much ineffective.
Described storage tank 76 is provided with through hole 760, the housing that electric drill 7 corresponds to through hole 760 position can be dismantled, described through hole 760 is twisted and is provided with stubborn cap 761, in the long-time use procedure of electric drill, if desired in body 78, increase or change the words of cooling water, only need to dismantle the housing that electric drill 7 corresponds to through hole 760 position, turn on stubborn cap 761, add in through hole 760 or pour out cooling water.
