Description
Technical field
The present invention relates to extraction tools, and in particular to a kind of turnkey fixing device and turnkey.
Background technology
Current extraction tool is substantially manually, extraction be part take time and pain thing, especially pull out firm
Hardly possible extraction, such as wisdom tooth or premolar teeth distomolar used extraction straight elevator to be inserted into gap between corona neck and alveolar bone wall in the past,
It is inserted into strength, side insert edge is endured, but since gap very little is very tight, therefore also needs to drive in very son using hammer very opening some gaps
It goes to realize and gradually be inserted into, it is such to be endured when striking；Or it cuts gum and turns over valve；Or divide root with turbine；Or steel is frustrated to remove and is somebody's turn to do
The alveolar bone on tooth periphery；Or it clamps tooth and shakes one or two hour and tooth is shaken down.
These methods are easy to be caught broken when having tooth pulled out and very broken tooth, and it is more troublesome to draw root, damages bigger.And the above method pulls out surely
Gu tooth is time-consuming and laborious, the thing that a tooth half an hour is frequent is pulled out, is also easy to bleeding, damage gum, alveolar bone, parodontium, or even damage
Hinder upper tooth and close sinus and lower alveolar duct, and then causes infection and pain.

Specific implementation mode
The turnkey fixing device and turnkey of the present invention are described in more detail below in conjunction with schematic diagram, wherein
Illustrating the preferred embodiment of the present invention, it should be appreciated that those skilled in the art can change invention described herein, and still
So realize the advantageous effects of the present invention.Therefore, following description should be understood as the widely known of those skilled in the art,
And it is not intended as limitation of the present invention.
Shown in please referring to Fig.1 to Fig.3, this practicality proposes a kind of turnkey fixing device and turnkey easy to operate.
Turnkey fixing device includes fixed plate 1 and claw 6.
The bottom side of fixed plate 1 sets the sliding slot 4 there are two right-angled intersection, and 4 slot bottom of sliding slot is equipped with ratchet 5, and the four of two sliding slots 4
A end is separately installed with a claw 6；Claw 6 includes sequentially connected straightway 61 and tilting section 62, and tilting section 62 is towards admittedly
Fixed board 1 it is centroclinal, the free end of straightway 61 is slidably connected in sliding slot 4 and the end face of straightway 61 is equipped with and ratchet 5
The grab 63 of cooperation.Ratchet 5 and grab 63 coordinate so that the movement of 6 one direction of claw, i.e., move towards 1 center of fixed plate, treat
The tooth of extraction, which is realized, to be fixed.Preferably, claw 6 is equipped with skid resistant course 64 with teeth contact face, further enhances fixed stabilization
Property.
