Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
Referring to Fig. 1~Fig. 4, a kind of hand-held boring device of the present invention, including trepanning motor 10, drill body 20
And the control switch 30 for controlling the action of trepanning motor 10, control switch 30 are installed on the side of trepanning motor 10, drill bit
Ontology 20 is connected with the output end of trepanning motor 10.Drill body 20 includes shaft 21, the first aperture portion 22 and the second trepanning
Portion, the first aperture portion 22 are conical structure and are fixed on the bottom end of shaft 21.Second aperture portion is set to the first aperture portion 22
Top, the second aperture portion rotates 21 equally distributed trepanning straight knife 231 of axle portion including at least two.The one of trepanning straight knife 231
End is rotatably connected with shaft 21 by rotating member 232, and rotating member 232 can be axis pin part.The madial wall of trepanning straight knife 231 is
Blade-like structure or thread-like structure suitable for trepanning.The structures such as trepanning straight knife 231 or semiannular shape, plate, are being opened
The surface of hole straight knife 231 is arranged corresponding aperture lines, and shaft 21 drives 231 high speed rotation of trepanning straight knife that can be formed when use
The cutting structure of cone-shaped is cut.Limiting slot is offered on the lateral wall of trepanning straight knife 231.Be fixed on shaft 21 with
The matched rest block 24 of limiting slot thus prevents during trepanning trepanning straight knife 231 and shaft 21 to occur relatively inclined
It moves, open-celled structure is made to stablize.Rest block 24 is set to the downside of rotating member 232.Rest block 24 is downwardly turned over for trepanning straight knife 231
When it is shelved.When trepanning straight knife 231 is held in rest block 24, between the free end of two trepanning straight knives 231 away from
From the basal diameter more than the first aperture portion 22.
The both sides of trepanning motor 10 are also respectively fixed with L-shaped holding handle 40, hold and are arranged with anti-slip rubber on handle 40
Set.
Several and matched glove groove 211 of trepanning straight knife 231 shape, rotating member 232 are offered on shaft 21
It is installed on the bottom of glove groove 211.It is temporarily stored into glove when by glove groove 211 trepanning straight knife 231 being flipped up
In groove 211.
Further include auxiliary body, auxiliary body include positioning transverse slat 51, inserted link 52 and with 52 matched sleeve of inserted link
53.Reach through hole is offered on positioning transverse slat 51, there are two sleeves 53 and is symmetrically set in the both sides of drill body 20.The one of sleeve 53
End is fixedly linked with trepanning motor 10, and there are two inserted links 52 and its respective one end is individually fixed in the both sides for positioning transverse slat 51.
The other end of inserted link 52 is arranged in the other end of the sleeve 53 corresponded to.Buffer spring 54, buffering elastic are arranged on inserted link 52
The both ends of spring 54 are fixed with trepanning motor 10 and positioning 51 phase of transverse slat respectively.
The bottom for positioning transverse slat 51 is equipped with several circular anti-skid bulges 60.Anti-skid bulge 60 includes that shape is identical and successively
Four scallops of distribution.Several teeth portion being obliquely installed are respectively fixed in four scallops, in adjacent two scallops
61 axial symmetry of teeth portion setting.Since the teeth portion 61 in four scallops is tilted along at least four directions respectively, to can avoid
Object to be punctured occurred level during trepanning moves.
