The utility model has the advantage of reasonable structure, can guarantee that the false phenomenon of pressing from both sides can not appear in clamp when pressing from both sides the car needle, increase the pressing force that the needle was got to the cell -phone simultaneously, make the tissue of doctor flip the oral cavity according to the last item during operation in the patient oral cavity in, can not result in the car needle to come off to lead to the fact and fly the needle phenomenon.
Description
Technical field
The utility model is related to a kind of pressing axis with spring, it is specifically a kind of with dental handpiece with resetting
The pressing axis of spring.
Background technology
The pressing of existing dentistry takes pin mobile phone pressing movable part and is assembled in axle sleeve the inside together with folder spring, and pressing takes complete after pin
It is full pressing movable part is rejected by pressing from both sides the screen resilience of spring, so it is easy to appearance folder spring and pressing movable part is pressed from both sides dead, cause back
If bullet not or doctor when cavity interior operating handset works cell phone rear cover top to intraoral tissue pressing movable part
Folder spring will be strutted causes chucking power not accommodate power not enough or directly to cause the car pin flying needle that comes off to damage patient.
Utility model content
The purpose of this utility model is to provide a kind of pressing axis with spring, and its pressing axis is using the side of back-moving spring
Formula is installed, it is ensured that folder spring is not in false folder phenomenon when car pin is pressed from both sides, while increasing the pressing force that mobile phone takes pin, is suffering from doctor
Pressing axis flips intraoral tissue during person mouthful transluminal operation, car pin will not be caused to come off and cause flying needle phenomenon.
Technical solution of the present utility model is, in axle sleeve, on the basis of folder spring, to be characterized in pressing piece, activity
Part, spring, described pressing piece, movable part, folder spring are sequentially inserted into axle sleeve and install from the front to the back, and spring housing is in movable part
Rear, one end of spring heads on the snap ring in axle sleeve, and the other end heads on pressing piece, and the front end of pressing piece is inserted into card in movable part
Tightly, tail protrusion position is exposed at axle sleeve tail end；Be provided with inclined plane on described movable part front end cylinder, and with folder spring
Y type fork mouthful is relative, and movable part can move forward the folder needle track of the Y type fork big folder spring of intraoral support for being inserted into folder spring.
Operation principle of the present utility model be by installing return spring between pressing piece and movable part, make pressing piece with
Movable part has enough screen resiliences, so can effectively prevent from touching by mistake the flying needle phenomenon for causing, while taking pin and folder pin process not
Can be because laying dust or other objects be deposited in the false folder phenomenon caused on folder spring.
The utility model has the advantages that it is rational in infrastructure, can ensure that folder spring is not in false folder phenomenon when car pin is pressed from both sides, while
Increase the pressing force that mobile phone takes pin, doctor's pressing axis in patient mouthful transluminal operation is flipped intraoral tissue, will not lead
Cause car pin to come off and cause flying needle phenomenon.
