Rear end be fixedly connected with the front side of knob 1, the front end of pressure spring 8 is fixedly connected with pressing plate 9, and pressing plate 9 is made by the elastic force of pressure spring 8
With forward movement, the surface of pressing plate 9 offers rectangular opening and is slided by the limit of the surface of rectangular opening and rectangular shaft 2, pressing plate 9
Front side is fixedly connected with friction sleeve 10, after the front side of friction sleeve 10 and the rear side of frame 1 fit closely, rectangular shaft 2 no longer with
Meaning rotation；And after clamping pressing plate 9 manually and moving backward, friction sleeve 10 and the rear side of frame 1 are disengaged, pressing plate is passed through
9 with the cooperation of rectangular shaft 2, rectangular shaft 2 can be made to rotate together with pressing plate 9；Guide post 3 rotates synchronously, and the front side of friction sleeve 10 can
It is flexibly connected with the rear side of frame 1, the front side of frame 1 offers through-hole and has screw rod 11, screw rod 11 by through-hole rotation-limited
Rear end be fixedly connected with knob 2 17, the surface of knob 2 17 offers anti-skid chequer, by the setting of knob 2 17, so that spiral shell
The rotation of bar 11 is more convenient, and anti-skid chequer opens up thereon, so that rotation is more laborsaving, the rear side of frame 1 is rotatably connected to
Two symmetrical cambered surface faggings 12, the opposite side of two cambered surface faggings 12 slidably connects stripper plate 13, the top of stripper plate 13
It is arcwall face with bottom, and stripper plate 13 is slidably connected by the surface of arcwall face and cambered surface fagging 12, passes through stripper plate 13
The setting of upper arc surface keeps the sliding between stripper plate 13 and cambered surface fagging 12 more smooth, and the surface of stripper plate 13 offers
Threaded hole is simultaneously spirally connected by the surface of threaded hole and screw rod 11, after screw rod 11 rotates, the stripper plate that is threadedly engaged with screw rod 11
13 have the tendency that rotating therewith, but under the limitation of gag lever post 14, stripper plate 13 can not be rotated, i.e., with screw rod 11
It produces relative rotation, after screw rod 11 rotates, stripper plate 13 will do it back-and-forth motion, can be gradually by two when its Forward
Cambered surface fagging 12 struts, and extruding is contacted and generated with the upper lower wall in patient oral cavity, while the oral cavity of patient is softened, and then make to fill
Set it is whole fixed, conversely, when moving back, two cambered surface faggings 12 can release it is above-mentioned grip, and by device entirety
It is taken out from patient oral cavity, the surface of stripper plate 13 offers through-hole and slidably connects gag lever post 14, gag lever post by through-hole
14 quantity is two, and two gag lever posts 14 are symmetrical arranged with the horizontal center line of screw rod 11, passes through two gag lever posts 14
Setting, so that the stress of stripper plate 13 more balances, when movement, is more stable；The front end of gag lever post 14 and the rear side of frame 1 are solid
Fixed connection.
Working principle: when in use, rectangular shaft 2 is arranged in guide post 3 protecting device special for dental clinical tooth preparation
The upper rear end by proximal edge is fixedly connected, due to the setting of eccentric position, so that rectangular shaft 2 carries out eccentric turn with guide post 3
It is dynamic, during continuous rotation, frame 24 can be made to move up and down under the limitation of locating rod 5；Protective plate 6 is synchronous with frame 24
It moves up and down, when protective plate 6 moves to bottom, the tongue of patient can be pressed in bottom, it similarly, can be by tongue when moving to top
It is fixed on maxilla wall, enables the tongue of patient to there is more place to select, and can also be by enough protections；
Under the elastic force effect of pressure spring 8, so that pressing plate 9 is fitted closely with friction sleeve 10 and the rear side of frame 1；Before friction sleeve 10
After the rear side of side and frame 1 fits closely, the no longer arbitrarily rotation of rectangular shaft 2；And after clamping pressing plate 9 manually and moving backward,
Friction sleeve 10 and the rear side of frame 1 are disengaged, by the cooperation of pressing plate 9 and rectangular shaft 2, rectangular shaft 2 can be made with pressing plate 9 one
Play rotation；Guide post 3 rotates synchronously；After screw rod 11 rotates, the stripper plate 13 being threadedly engaged with screw rod 11 has to be turned therewith
Dynamic trend, but under the limitation of gag lever post 14, stripper plate 13 can not be rotated, i.e., produce relative rotation with screw rod 11,
After screw rod 11 rotates, stripper plate 13 will do it back-and-forth motion, when its Forward, can gradually support two cambered surface faggings 12
It opens, extruding is contacted and generated with the upper lower wall in patient oral cavity, while the oral cavity of patient is softened, and then consolidates device integrally
It is fixed, conversely, when moving back, two cambered surface faggings 12 can release it is above-mentioned grip, and it is device is whole from patient oral cavity
It takes out；By solving in actual use, due to the electricity in conventional apparatus by being used cooperatively between above structure
The stability of dynamic telescopic rod in use is insufficient, is easier to break down for relatively simple supporting mechanism；Tongue simultaneously
The tongue that anti-guard block is difficult for patient provides multiposition fixed placement, it is difficult to which the diversity requirement for meeting patient is brought to using
Inconvenient problem.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
