Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the present invention is by bistrique 1 and the mill that is connected with described bistrique 1
Handles etc. form, and be shaped as cylindricality, front end and the side face of described bistrique are provided with cutting edge or gold
Emery, in order to grinding or reconditioning osseous tissue, described bistrique 1 is located in support bar by mill handle
In 2, the external diameter of described support bar 2 is more than the external diameter of bistrique 1；At described support bar 2
Outer sheath is provided with support ring 3, and described support ring 3 is cydariform, the outside of described support ring 3
Face is provided with at least one groove 32, is provided with clamping screw 31 in described support ring 3, described
Clamping screw 31 is spirally connected and is fed through support ring 3, and abuts solid with the correspondence position of support bar 2
Fixed.
As shown in Fig. 1, Fig. 3, Fig. 4 and Fig. 5, described support bar 2 is axially arranged with tooth
Shape structure, this support bar 2 is provided with stopping means, described stopping means includes control
Button 21, lever 22 and governor motion, described governor motion includes latch 41, described
The inside of lever 22 is provided with " ten " font cavity, and described control knob 21 is positioned at " ten "
In the horizontal segment cavity of font cavity, described latch 41 is positioned at the vertical of " ten " font cavity
In section cavity, on described latch 41 and control knob 21, the one end towards cavity inside all connects
There is spring 42；One end that described contiguous block 42 stretches into horizontal segment cavity be provided with one section in outside height
Low step-like flat structure, is the oblique section of transition 43 at the step of described step-like flat structure；
The middle part of described step-like flat structure is provided with upper and lower through bar-shaped trough 44, described latch
One end of 41 is provided with one section of flat bar suitable with bar-shaped trough 44 shape, described flat bar
It is fed through bar-shaped trough 44, and makes the step end face of flat bar upper end top bar with control knob 21
The end face of shape flat structure abuts and slides.
The using method of the present invention is as follows:
By shown in Fig. 1 to Fig. 5, be shaped as cylindricality, front end and the side face of bistrique 1 are provided with and cut
Cut sword, first the mill handle being connected on bistrique 1 is fed through support bar 2, exposes bistrique 1, then
Hand-held operation handle 22, pins control knob 21 and inwardly extrudes (the diagram level left finger direction of arrow)
The spring 42 of correspondence position, simultaneously as bar-shaped trough 44 be one section with the oblique section of transition 43
Low inside and high outside step-like structure, the one end adding latch 41 is provided with one section and bar-shaped trough
The flat bar that 44 shapes are suitable, flat bar is fed through bar-shaped trough 44, and makes flat bar upper end
Appear on the stage with control knob 21 end face of scalariform flat structure of step end face abut slip, so,
When bar-shaped trough 44 moves inward, the upper surface of step-like flat structure slides against flat rod
The step end face of upper end, and make latch 41 move down, now, on stopping means, one end is worn
If being socketed on support bar 2, unclamping control knob 21, control knob 21 is at corresponding spring 42
Under effect protruding, latch 41 moves up the most therewith, and makes the disconnected of latch 41
End inserts in the correspondence position of dentalation, it is achieved positioning limit.
Again support ring 3 is socketed in the lateral surface of support bar 2, clamping screw 31 of riveting tightly,
In actual application, auxiliary tube tool (sign) on the outside of support ring 3 is overlapped again,
Support ring 3 is mobile in auxiliary tube has, swinging operation handle 22 simultaneously, swing grinding operation position
Put；Such as the position of stopping means to be adjusted, pin control knob 21, repeat the above steps, hands
Dynamic hold lever 22, make stopping means transverse shifting locking on support bar 2；
The scope swung such as bistrique 1 to be adjusted, takes out support bar 2 from auxiliary tube has, unclamps lock
Tight bolt 31, the position of mobile support ring 3, after adjusting properly, locking of again riveting tightly
Bolt 31, can be continuing with in being inserted in auxiliary implement.
The lateral surface of described support ring 3 is provided with at least one groove 32, is in order in grinding
Journey is easy to injection and air-out or water, it is simple to clean grinding position.
In addition, it is necessary to when to operative site reconditioning, front end and side face can be selected to be provided with
The cylindricality bistrique 1 of corundum.
It is consistent with prior art that the present invention does not describes part, and therefore not to repeat here.
These are only embodiments of the present invention, not thereby limit the scope of the claims of the present invention,
Every equivalent structure utilizing description of the invention and accompanying drawing content to be made, directly or indirectly uses
In the technical field that other are relevant, the most in like manner within the scope of patent protection of the present invention.
