Specific embodiment
Below in conjunction with the accompanying drawings, the design and use to the present invention further illustrate.
Introduce the function of part：
Grip shank 1：It is shaped as shaft-like, one end is clamped by rig, the other end and circular rotating box 6 connect, and
Box 6 is rotated rotate.Rig can be electric hand drill.
Abrasive sheet 4：When rotating box 6 does not rotate, abrasive sheet 4 againsts the side wall of rotating box 6,6 turns of rotating box
After moving a certain speed, abrasive sheet, due to the principle of centrifugal force, starts to move out, thus to abrasive sheet 4
The object (namely Porous materials to be drilled) of contact produces the effect of grinding.
Grinding layer 5：Made with the material beneficial to grinding, grinding layer 5 is attached to abrasive sheet 4 surface, that is,
Say：There is the grinding layer 5 for grinding in the outside of abrasive sheet 4.
Rejection tablet 3：One end connects abrasive sheet 4, and axle 2 is got rid of in other end connection.
Get rid of axle 2：For the axle allowing rejection tablet 3 to rotate.
Rotating box 6：Inside has to allow gets rid of the mechanism that axle 2 playbacks.
Limit axle bed 22：Determine the axis getting rid of axle 2.Get rid of axle 2 one end insertion limit axle bed 22, the other end stretches out rotation
Turn box 6.Each limit axle bed 22 is inserted into one end that a cylinder gets rid of axle 2.
Spacing ring 21：Prevent from getting rid of axle 2 disengaging limit axle bed 22.
Helical spring 23：Do not turn (or when slowly running) in rotating box 6, make abrasive sheet 4 be fitted in rotating box
6 side wall, plays the effect of playback.In order to allow helical spring 23 can apply strength, two ends are needed to fix：
One end is fixed on gets rid of axle 2, and the other end is fixed on fixed pole 231 it is therefore apparent that fixed pole 231 needs and rotating box
6 are fixedly connected.
Second chip removal flute 41：Grinding layer 5 grinding chip out is discharged near grip shank 1.
First chip removal flute 11：The chip that second chip removal flute 41 is discharged discharges boring.
Embodiment one：
Referring to accompanying drawing 1, it is the left view of the present invention, the statement of book for convenience of description, and in order that picture
Look not in disorder, this figure eliminates section components, omitting in these accompanying drawings 1 and necessary part will be
This specification other paragraphs ensuing are expressed.
From mechanical knowledge, when object moves in a circle, if centripetal force is not enough, will be far from the center of circle.
In accompanying drawing 1, grip shank 1 is fixedly connected with circular rotating box 6, and the surfaces of revolution of rotating box 6 is perpendicular to folder
Hold the rotation axiss at handle 1 place, and the barycenter of rotating box 6 is a bit of grip shank 1 rotation axiss place, gets rid of
The other end of axle 2 stretches out rotating box 6 and is fixedly connected rejection tablet 3, and each gets rid of axle 2 and connects a rejection tablet 3,
Rejection tablet 3 place plane is perpendicular to the rotation axiss of grip shank 1, and rejection tablet 3 is having away from that one end getting rid of axle 2
Perpendicular to the abrasive sheet 4 of rejection tablet 3, abrasive sheet 4 is fixedly connected with rejection tablet 3, and abrasive sheet 4 is in circular arc, and
The radius of curvature of its internal diameter is equal to the radius of rotating box 6, and there is the grinding layer for grinding in the outside of abrasive sheet 4
5, grinding layer 5 can make (removing material belongs to prior art) with hard material.
Referring to accompanying drawing 2, be the present invention in working order under left view.In rig high-speed rotation, rejection tablet 3
Get rid of axle 2 with abrasive sheet 4 drive to rotate, radius increases, thus grinding goes out male ports.That is：Abrasive sheet
4 can drive and get rid of axle 2 and rotate, so that abrasive sheet 4 is away from grip shank 1 place axis.
Referring to accompanying drawing 3, it is front view of the present invention, this figure stresses to express rotating box internal structure.Away from clamping
Handle 1 and inwall (this inwall place plane is perpendicular to rotation axiss of the grip shank 1) fixation in rotating box 6
Connect the limit axle bed 22 of two ring-types, each limit axle bed 22 is inserted into one end that a cylinder gets rid of axle 2, gets rid of
Axle 2 place diameter parallel, in the rotation axiss of grip shank 1, is got rid of the spacing ring 21 that axle 2 is also cased with ring-type, is got rid of
Axle 2 is fixedly connected with spacing ring 21, and spacing ring 21 is located at the inside of rotating box 6, and againsts rotating box 6
Inwall, and this inwall is relative with the inwall of fixing limit axle bed 22, in spacing ring 21 with limit between axle bed 22,
Get rid of axle 2 and pass through a helical spring 23, one end of helical spring 23 is fixedly connected on gets rid of axle 2, and the other end is solid
Surely it is connected to fixed pole 231, fixed pole 231 is fixedly connected on the inwall of rotating box 6, and this inwall and connection limit axle
The inwall of seat 22 is same inwall.
In order to illustrate how chip removal, referring to accompanying drawing 4, there is the second chip removal flute 41 for chip removal on abrasive sheet 4 surface,
Because there being more chips to pass through the second chip removal flute near-end 412, the depth of the second chip removal flute far-end 411
More shallow than the depth of the second chip removal flute near-end 412, grip shank 1 surface has for chip removal, helically shape
First chip removal flute 11.Second chip removal flute 41 can make straight flute.Second chip removal flute 41 can have a plurality of.
Although " shallow " belongs to unclear statement in itself, in the case of having and comparing, " shallow " belongs to
Clearly state.
In order to prevent shaking, the barycenter of the entirety of all rejection tablets 3 and abrasive sheet 4 composition is grip shank 1 rotation axiss institute
A bit.
Embodiment two：
Can there are three groups and get rid of axle in rotating box 6, and corresponding rejection tablet 3, abrasive sheet 4, spacing ring 21, limit axle
Seat 22, helical spring 23, fixed pole 231.Various equivalent modifications should know：In order to prevent shaking,
The barycenter of the entirety of all rejection tablets 3 and abrasive sheet 4 composition is a bit that grip shank 1 rotation axiss are located.
