Background technique
Dental handpiece is a kind of common oral cavity medical apparatus, and the vehicle needle of different shape is cooperated by high speed rotation, can
Positioning drilling is carried out to oral hard tissue, expansion is even cut, and currently used dental handpiece includes handle, is located at handle one
The hand machine head at end, the vehicle needle being connected outside head and through clamp with hand machine head.But existing dental handpiece is in the presence of as follows
Problem: 1) doctor is difficult to hold to the depth drilled through；2) doctor is when operation dental handpiece drills to patient, dental handpiece
Stability it is not high；3) since the sleeve on current dental handpiece can only carry out the replacement of length, and cannot to sleeve size into
Row replacement, thus encounter patient's adjacent teeth gap it is smaller when, being difficult to of doctor carries out stable operation, to influence surgical effect.
Utility model content
The utility model provides a kind of dental handpiece, it can be achieved that drilling through the quick positioning of depth；And doctor is in operating process
In, stability improves；The sleeve and different oral environments of different-diameter size can be applicable in.
To achieve the above object, the utility model adopts the following technical solutions.
A kind of dental handpiece, including handle, the hand machine head being fixedly connected with handle, sleeve connection pipe, sleeve assembly and use
In the vehicle needle of drilling, the sleeve connection pipe is fixed on mobile phone end surface, and the vehicle needle is fixed on the sleeve connection pipe will
Mobile phone end surface surrounds the center in region, and the sleeve connection tube outer surface is equipped with the first external screw thread, the sleeve connection pipe
Inner surface is equipped with the second internal screw thread；The sleeve assembly includes first sleeve and second sleeve；The first sleeve and sleeve connect
The junction of adapter tube is equipped with the first internal screw thread, and first internal screw thread matches with the first external screw thread；The second sleeve and set
The junction of cylinder connecting tube is equipped with the second external screw thread, and first internal screw thread matches with the second external screw thread.
Further, the first external screw thread, the first internal screw thread, the second external screw thread and the second internal screw thread are buttless thread, sawtooth
Screw thread has higher stable connection compared with general screw thread.
Further, the outer wall of first sleeve and second sleeve is equipped with several thermal vias.
Further, the diameter of the thermal vias is 1mm.
The utility model has the following beneficial effects: the utility model provides a kind of dental handpiece, including handle, fix with handle
Hand machine head, sleeve connection pipe, sleeve assembly and the vehicle needle for drilling of connection, wherein sleeve connection tube outer surface is equipped with first
External screw thread, the sleeve connection pipe internal surface is equipped with the second external screw thread, therefore the sleeve connection pipe can connect different-diameter
Sleeve, therefore the utility model is applicable in different planting tools and different oral conditions；The utility model passes through sleeve and vehicle
Relative altitude between needle realizes the quick positioning for drilling through depth；The utility model middle sleeve component is directly anchored to hand machine head
On, therefore doctor's stability during operation improves.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of dental handpiece described in the utility model.
Fig. 2 is the structural schematic diagram of first sleeve described in the utility model.
Fig. 3 is the structural schematic diagram of second sleeve described in the utility model.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
