The utility model has the advantages that
A kind of small-bore round tube angle bistrique of the utility model, compared to having for the milling tools such as existing file, angle grinder
There is following advantage:
The first, bore is scalable, the small-bore round tube angle bistrique of the utility model, including center connecting shaft, and the center connects
The bottom end of spindle and the auger spindle of power drill connect；It is connected with diameter changing mechanism on the outer wall of the center connecting shaft, when the center
When around own axes rotation occurs for connecting shaft, the diameter of the diameter changing mechanism can connect under the influence of centrifugal force to far from center
The direction of axis line of axis becomes larger.
The second, in the small-bore round tube angle bistrique of the utility model, the arc angle polishing slate and the arc plate unit it
Between plug connection can facilitate replacement when angle s-bone wear is unavailable.
It is different according to the round tube diameter that need to be polished in the small-bore round tube angle bistrique of third, the utility model, it can make
Multiple Type, in use, direct image drill bit is equally connected on the auger spindle of power drill, using quick, efficiently.
