Be provided with illumination light-conductive optic fibre 14 in described handpiece case 1, described illumination light-conductive optic fibre 14 heads are arranged between pin 5 and handpiece case 1.
Operation principle of the present invention is, tooth sector in rotor assembly is mutually meshing with the motor rotary head in handpiece case one side extension, and under the drive of motor rotary head, tooth sector also rotates with the motor rotary head, thereby transmit power to axle core place, make the pin in the axle core rotate.When needs change pin, press Ka Zhengai, the needle ring that changes of card pin lid bottom is moved down, changing under the suppressing action of needle ring, the card dials valgus of elastic insulated material is gradually softened, and the disk of card dials bottom also struts thereupon, olive caryogram through hole in the middle of disk is finally circular by support, make the afterbody of pin be able to by, at this moment, pin can be taken out; When needs dresses pin, as long as press Ka Zhengai, after making the olive caryogram through hole of disk circular, the afterbody of pin is injected, then decontrol the Ka Zhengai pressed, the pin of can packing into.
The invention has the advantages that:
1, simple for structure, durable, safety, mould is easily made, and parts are easily produced.
Stab finger while 2, having avoided dress to get pin, eliminated the head dead space and formed, avoided the generation of cross infection.
3
,because the setting of card dials, make the afterbody of pin obtain good fixing, no matter make is that card dials or the afterbody of pin all increase the service life.
4
,this structure is few to the Effect of Rotation of pin, can effectively improve the rotary speed of pin.
5
,can make the effective measuring distance of root canal by built-in location sensitive sheet.
6
,by can the throw light on effective brightness in the root tube chamber visual field of built-in light conducting optical fiber lamp.
