A kind of adjustable electrodrillTechnical field
The present invention relates to electrical equipment, a kind of adjustable electrodrill is specifically related to.
Background technology
It is frequently necessary to use electric drill in daily finishing in the specified orientation drilling such as metope or plate face, existing electric drill is typically heavier,Need to hold with a firm grip electric drill handle on the other hand, another hand steered electric drill body, alignment jewel hole carries out boring action, and labor intensity is larger, togetherShi Kongrong is easily crooked, accordingly, it would be desirable to design a kind of simple to operate, electrodrill that can be reduced labor intensity.
The content of the invention
To solve the above problems, the invention provides a kind of adjustable electrodrill, its is simple in construction, easy to use,Electric drill support can be given in operation, reduced labor intensity.
A kind of adjustable electrodrill of the present invention, its technical scheme used is including electric drill body and perpendicularDirectly it is located at the drill bit below the electric drill body, it is characterised in that the electric drill body is provided with regulating member, the adjustment portionPart includes connector, adjustable plate, location-plate, support bar and spring, and the connector is actively installed on the electric drill body, describedIt is disposed in parallel relation to one another and is connected respectively with the connector above and below location-plate and the adjustable plate, the lower end of the support bar is successivelyThrough the location-plate and the adjustable plate and parallel with the drill bit, it is provided with vertically between the adjustable plate and the location-plateSlide rail, the support bar is slidably connected by sliding block with the slide rail, and the spring is set on the support bar and positioned at instituteState between location-plate and the sliding block.
It is preferred that, the support bar is provided with length scale.
They sup-port can give the support of electric drill body on bore surfaces, mitigate the dynamics of hand steered electric drill, reduction workIntensity；In drilling, drill bit drills on drilling area, when drill bit is stretched into drilling area, and the motion of electric drill drives support bar to electric drillBody upper end is shunk, and sliding block slides along slide rail, and compression spring, when drilling is finished, drill bit is exited out of drilling area, spring it is anti-Elastic force drives support bar to reset；In the case where being not required to run through drilling area, it is difficult to judge the depth that drill bit is pierced, compare in drilling areaIn the case of, it is easy to cause to run through by mistake, therefore length scale is provided with support bar, when drill bit stretches into drilling area, supportBar is moved, the length moved according to support bar to location-plate direction due to drill bit to being pressed into motion of drilling area to location-plate directionTo judge depth that drill bit is pierced.
It is preferred that, the connector includes clip and bolt, and the clip is passed through provided with locking connector, the boltThe locking connector is threadedly coupled with matching nut, and clip is fixed on the electric drill body；It can be drilled according to drilling areaParticular location, rotating connector, to adjust the position of support bar, makes operation more simple.
Electric drill often produces flying chip in drilling, influences sight, seriously causes to damage to personnel while flying chip is easily splashed intoWound, to solve the above problems, it is preferred that, it is provided with inner hollow and lower section positioned at the lower section of the adjustable plate on the electric drill bodyBlower fan is provided with the bellows shell of opening, the bellows shell, the bellows shell is provided with the fan switch for controlling the blower fan.
It is preferred that, filter screen is provided with the opening of bellows shell, the lower section of the filter screen is provided with pendulum fan blade.
In drilling, blower fan starts, and flying chip is dispelled out, makes boring procedure clearer, operating personnel can observe at any timeThe situation of drilling.
The present invention has the beneficial effect that：Simple in construction, easy to use, operation is flexible, effectively alleviates labor intensity.
Brief description of the drawings
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawingThe present invention is described in further detail.
Fig. 1 is main structure diagram.
Fig. 2 is the connector overlooking the structure diagram.
Wherein, 1- electric drills body, 2- drill bits, 3- regulating members, 31- connectors, 311- clips, 312- bolts, 313- locksClamping joint, 32- adjustable plates, 33- location-plates, 34- support bars, 35- springs, 36- slide rails, 37- sliding blocks, 4- bellows shells, 41- pendulumFan blade, 5- fan switch.
Embodiment
As illustrated, a kind of adjustable electrodrill, including electric drill body 1 and it is located at vertically under the electric drill body 2The drill bit 2 of side, the electric drill body 1 is provided with regulating member 3, and the regulating member 3 includes connector 31, adjustable plate 32, determinedPosition plate 33, support bar 34 and spring 35, the connector 31 include clip 311 and bolt 312, and the clip 311 is provided with lockClamping joint 313, the bolt 312 is threadedly coupled through the locking connector 313 with matching nut, and clip 311 is fixedOn the electric drill body 1；The location-plate 33 and the adjustable plate be disposed in parallel relation to one another about 32 and respectively with the connectionPart 31 is connected, and the lower end of the support bar 34 sequentially passes through the location-plate 33 and the adjustable plate 32 and flat with the drill bit 2OK, slide rail 36 is provided between the adjustable plate 32 and the location-plate 33 vertically, the support bar 34 is by being installed in thereonSliding block 37 is slidably connected with the slide rail 36, the spring 35 be set on the support bar 34 and positioned at the location-plate 33 withBetween the sliding block 37；The support bar 34 is provided with length scale.
Positioned at bellows shell 4 of the lower section of the adjustable plate 32 provided with inner hollow and lower opening on the electric drill body 1,Filter screen is provided with the opening of bellows shell 4, the lower section of the filter screen is provided with pendulum fan blade 41, and the bellows shell 4 is interior provided with blower fan, describedBellows shell 4 is provided with the fan switch 5 for controlling the blower fan.
For the ease of it is concise judge length scale that drill bit pierced on the depth of drilling area, support bar preferably from it is fixedThe position of position plate upper surface flush is risen engraves length scale downwards；During drilling, according to borehole environment and angle requirement, spiral shell is unclampedBolt, rotates clip, and support bar is adjusted to suitable position and starts drilling operation, and blower fan starts, adjustment pendulum fan blade, is directed at windDrilling, the flying chip of splashing is blown open, drill hole is remained cleaning, and they sup-port is on drilling area, and drill bit drives electric drill sheetBody is pressed into drilling area direction, so that location-plate exceeds location-plate upper surface to boring direction compression spring according to support barScale length judge that drill bit stretches into the depth of drilling area.
The preferred scheme of the present invention is the foregoing is only, limitation of the invention further is not intended as, it is every to utilize thisThe various equivalence changes that description of the invention and accompanying drawing content are made are within protection scope of the present invention.
