Described mounting disc specifically uses three width spirals to arrange；Described mounting disc is connected to spiral head especially by latch
Junction with central authorities' drill bit, it is simple to dismounting, can discharge chip smoothly and be easy to take out in boring procedure simultaneously
Drill bit, prevents drill chuck at bore inner.
Described annular bit is uniformly arranged in mounting disc and tilts to central authorities drill bit direction；The rotation of described annular bit
Turn center consistent with the center of rotation of central drill bit, be conducive to synchronizing to exert a force to drilling structures, prevent borehole trajectory from deviateing.
Described sidetracking head is arranged on the end of mounting disc by tail end fixing port grinding tooth and threaded engagement；Described sidetracking
Head tilt direction is consistent with annular bit, installs additional when boring outer wall is had certain planarization requirement, desirably prevents to bore simultaneously
Hole track deviation.
Described connecting rod uses arc；Form a circle being interrupted between described connecting rod, be conducive to further
Ensure the planarization of borehole sidewall, and avoid borehole trajectory to deviate.
There is advantages that the accurate Drilling bore bit of a kind of anti-deviation due to the present invention, can extensively answer
For rig technical field.Meanwhile, the invention have the benefit that
Being equipped with of central authorities the most of the present invention drill bit, annular bit and sidetracking head, is conducive to remaining capable in boring procedure
Enter the stability of track, prevent borehole trajectory deviation, the simultaneously setting of sidetracking head, be conducive to borehole sidewall is carried out at slickness
Reason, promotes drilling effect.
Mounting disc the most of the present invention and the activity installation of sidetracking mill structure, it is simple to dismantle and use flexibly, can make according to actual
Treat with a certain discrimination by the difference of situation.
The arc of connecting rod the most of the present invention is arranged, and beneficially sidetracking head running orbit and central authorities' auger spindle concentric running, prevent
Drill bit, because of the too strong damage of torsion, is conducive to increasing the service life.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described further:
Embodiment:
As shown in Figures 1 and 2
The present invention provides the accurate Drilling bore bit of a kind of anti-deviation, including axis 1, and spiral head 2, annulus 3, central authorities' drill bit 4,
Mounting disc 5, installing hole 6, annular bit 7 and sidetracking mill structure 8, described central drill bit 4 is arranged on axis 1 by spiral head 2
End；Described mounting disc 5 is connected to the junction of spiral head 2 and central authorities' drill bit 4 by annulus 3；Described annular bit
7 are fixed on mounting disc 5 surface by installing hole 6；Described sidetracking mill structure 8 is arranged on the end of mounting disc 5；Described side
Bore mill structure 8 and include that tail end fixing port 81, connecting rod 82 and sidetracking head 83, described connecting rod 82 connect sidetracking head 83 and tail end
Fixing port 81；Described tail end fixing port 81 activity is arranged on mounting disc 5 end.
Described mounting disc 5 specifically uses three width spirals to arrange；Described mounting disc 5 is connected to spiral especially by latch
