This utility model object is achieved in that
A kind of dental handpiece, comprise hand machine head, hand machine head bottom is provided with car pin, and described car pin outside is provided with safety sleeve, and safety sleeve is connected with hand machine head, and the lower end of car pin is stretched out outside safety sleeve.
Safety sleeve described in the utility model is divided into two kinds, one is external screw thread safety sleeve, one is female thread safety sleeve, the external wall of upper portion of external screw thread safety sleeve is provided with screw thread, female thread safety sleeve is then that the upper inside wall of sleeve is provided with screw thread, the diameter of usual female thread safety sleeve is larger, be applicable to the dental operation of general position, the oral cavity of energy available protecting patient, prevent from accidentally injuring, the length difference of safety sleeve and car pin can also be utilized to help doctor to control to drill through the degree of depth simultaneously, and when the position running into patients need operative is comparatively narrow, when female thread safety sleeve can not enter, external screw thread safety sleeve will be used, usual external thread sleeve diameter is less, the oral cavity that narrower position is patient can be entered protection is provided.
Technique scheme also can be made to the following further improve.
Described hand machine head bottom is provided with sleeve connection mouth, sleeve connection mouth internal perisporium is provided with the first female thread, safety sleeve external wall of upper portion is provided with first external screw thread corresponding with the first female thread, and the first external screw thread and the first screw-internal thread fit, make safety sleeve be fixed on hand machine head.
Described hand machine head bottom is provided with sleeve connection mouth, sleeve connection mouth periphery wall is provided with the second external screw thread, safety sleeve upper inside wall is provided with second female thread corresponding with the second external screw thread, and the second female thread coordinates with the second external screw thread, and safety sleeve is fixed on hand machine head.
Described sleeve connection mouth can be provided with the first female thread and the second external screw thread simultaneously, to facilitate adaptive dissimilar safety sleeve.
The sidewall of described safety sleeve has Cooling Holes, can be cooled to car pin by Cooling Holes over the course for the treatment of.
Described safety sleeve has the length of multiple different size, to be applicable to different positions and disease.
Compared with prior art, the beneficial effects of the utility model are as follows.
This utility model, by setting up safety sleeve in hand machine head bottom, reaches the security performance that effectively can improve dental handpiece, prevents the accidental injury produced in operation process; And by the safety sleeve at hand machine head bottom collocation different-diameter and length, can effectively control to drill through the degree of depth, effectively ensure the presupposed solution obtaining operative treatment, guarantee therapeutic effect; And safety sleeve can also with plantation guide plate with the use of, the position of the boring of implant in implant operation, angle and the degree of depth can be guaranteed, guarantee surgical effect to greatest extent.

Detailed description of the invention
Be described further below in conjunction with the many this utility model of drawings and Examples.
Composition graphs 2 to Fig. 4, is described in detail to embodiment 1.
A kind of dental handpiece, comprise hand machine head 2, hand machine head 2 bottom is provided with car pin 3, and the outside of car pin 3 is provided with external screw thread safety sleeve 5, and external screw thread safety sleeve 5 is connected with hand machine head 2, and the bottom of car pin 3 stretches out in outside external screw thread safety sleeve 5.
Described hand machine head 2 bottom is provided with sleeve connection mouth 4, sleeve connection mouth 4 internal perisporium is provided with the first female thread 41, external screw thread safety sleeve 5 external wall of upper portion is provided with first external screw thread 51 corresponding with the first female thread 41, first external screw thread 51 coordinates with the first female thread 41, and external screw thread safety sleeve 5 is fixed on hand machine head 2.
The sidewall of described external screw thread safety sleeve 5 has Cooling Holes 88, can be cooled, with the damage avoiding high temperature to produce sclerous tissues to because of car pin 3 heat that high-speed rotary transfers to produce in sclerous tissues by Cooling Holes 88 over the course for the treatment of.
