Description
Technical field
The present invention relates to hole making drill technical field, and in particular to a kind of adjustable hole making drill.
Background technology
Warming plate is a kind of plank that can be incubated to wall, when mounted, will be incubated usually using hole making drill
Plate surface carries out perforate, and is further fixed in wall using anchor studs.Traditional electric drill hole making drill, including can be with electricity
Bore provided with the crossbeam extended transversely through in the middle part of connected main shaft, main shaft, crossbeam two ends are arranged with drilling rod, drilling rod lower end is provided with knife
Head, main shaft lower end is equipped with drill bit, and drill bit lower end is less than cutter head lower end, and drilling rod is connected by sleeve pipe with crossbeam, sleeve pipe and crossbeam
Between fixed by trip bolt.The electric drill hole making drill cutter head be set to it is tip-shape, to warming plate carry out perforate when, can due to effect
It is too small and make it that electric drill hole making drill cutter head is concentrated to the stress of warming plate in the lifting surface area on warming plate, it is easy to cause insulation
Plate ruptures.
Anchor studs hole making drill is thus introduced, includes handle and the housing being connected with handle, handle bottom is set
There is on hanging hole, handle hand-held position set and anti-slip veins be provided with rubber sleeve, rubber sleeve surface, handle upper end be provided with by
Motor and the output shaft with motor connection are provided with pusher-type switch, housing, output shaft is stretched out on housing, housing relative to electricity
The opening for being provided with heat emission hole, housing and adding machine oil is vertically arranged with the outer wall of machine, opening is closed by a spiral cover, output
One end that shaft extension goes out is connected with drill bit, and drill bit is made up of granite, and one end of drill bit is set to half arcuate structure, half arcuate structure
Surface be set to mat surface.
The use principle of the anchor studs hole making drill is：When in use, drill bit is supported located at insulation plate surface, by opening electricity
Machine, output shaft can drive bit, because drill bit is made up of granite so with certain hardness, drill bit can be because of itself
Rotation and warming plate is rubbed, due to drill bit support located at insulation plate surface one end be set to half arcuate structure, so
The lifting surface area to warming plate can be increased, half arcuate structure surface is set to mat surface, drill bit and warming plate can be increased
The rubber sleeve set on Relative friction, handle enable to staff hand-held when increase comfort so as to slowing down
Fatigue, and when in use, anchor studs hole making drill can produce vibrations and rubber sleeve can play a part of setting on buffering, rubber sleeve
Anti-slip veins are equipped with, the palm of staff and the Relative friction of handle can be increased, can after drill bit uses the long period
Drill bit is changed to the surface of output shaft, then by extracting drill bit out by pressing spring leaf.
The handle is often coupled with the connection of housing via connecting piece, and current connecting piece is many, connect as silk,
The such structure of interlocking, will prevent that the handle and being coupled for housing are unstable, generally be coupled position in the handle and housing
Block rubber framework has been installed, but can still bring the defect for being unfavorable for dismantling and assemble repeatedly, even if useful in the prior art
In the connecting piece of dismounting and assembling, but structure is remarkable, is coupled unstable defect.
The content of the invention
To solve the above problems, the invention provides a kind of adjustable hole making drill, effectively reducing and being unfavorable in the prior art
