020 is connected, and the end cap 040 is sheathed on the periphery of button 010, elastic element 020, gasket 030 and gear shaft 050, institute
The opening 051 and fixture block 060 for stating 050 top side of gear shaft coordinate, and the split circlip 070 is sheathed on fixture block 060 and tooth
On the outside of 050 circumferencial direction of wheel shaft, the baroclinic block 011 of 010 bottom of the button is matched with the slanting baffle 061 of 060 top of fixture block
Realize the translation of fixture block 060.The device acts on the slanting baffle of fixture block 060 by using the baroclinic block 011 of the lower section of button 010
The effect of power on 061 makes fixture block 060 realize to circumference moving horizontally outward, and then is moved in the same direction with motor-car needle, realizes
The purpose that vehicle needle is deviate from from the bearing column endoporus inside gear shaft 050, and then realize the effect for facilitating needle exchange.Not to button
010 apply pressure under the action of, 010 one side of button by elastic element to the jacking force in its upward direction, while also by
The state being separated between button 010 and fixture block 060 is realized in limit to end cap 040 to its vertical direction, and vehicle needle is stablized at this time
Be located at 050 middle part fixed position of gear shaft, be convenient for surgical procedure.
As shown in figure 3, as further optimization, elastic element 020 is conical compression spring.Elastic element 020 it is upper
End is matched with button 010, and guarantee button 010 only exists vertical displacement, avoid caused by 010 horizontal position deviation of button with card
There is the phenomenon that deviation in cooperation between block 060, is effectively guaranteed the stability of position during vehicle needle use.
As shown in Figure 1 to Figure 3, the convex block 012 and conical compression bullet for passing through lower part as further optimization, button 010
The smaller diameter end of spring is interference fitted.The convex block 012 of the smaller diameter end of conical compression spring and 010 lower part of button realizes that interference is matched
It closes, ensures that conical compression spring and button 010 become an entirety, meanwhile, the smaller diameter end of conical compression spring is upward, big straight
Diameter end is downward, and the stability during conical compression spring-compressed may be implemented, and ensures the stabilization pressed in vehicle needle replacement process
Property, realize the effect of quick needle exchange.
As shown in figure 3, as further optimization, larger diameter end and 030 clearance fit of gasket of conical compression spring.Cone
The larger diameter end of shape compressed spring is correspondingly arranged with above gasket 030, and the vertical portion with gasket 030 is to cooperation, due to taper
Compressed spring upper end is interference fitted with the convex block 012 of 010 lower end of button, so in lower end and 030 vertical portion of gasket
Cooperation in be gap-matched, be easy to implement the smooth conversion that conical compression spring is in compressive state and elongation state, keep away
Exempt to press the formation excessive resistance of button 010, influences needle exchange speed.
As shown in Figures 1 to 6, as further optimization, fixture block 060 is close to 050 axis client of gear shaft and gear shaft 050
Internal bearing column contact.Fixture block 060 vehicle needle using when in applying stressed position to the bearing column inside gear shaft 050
It sets, the part of clamping trolley needle can be embedded into the endoporus of bearing column under the effect of the pressure of fixture block 060 at this time, clamping only
Vehicle needle, under the action of top button 010, fixture block 060 then forms one to vehicle needle and loosens work to periphery movable type
With enabling vehicle needle smoothly to take out out of gear shaft 050, be easy to implement the replacement of vehicle needle.
As shown in Figures 1 to 6, as further optimization, fixture block 060 is equipped with notch 062, the notch 062 with open
Mouth spring ring 070 coordinates.Notch 060 on fixture block 060 forms good mating reaction with split circlip 070, in button-free
Under the action of 010 pressing, i.e., in the state of vehicle needle normal work, what split circlip 070 can be stablized exists the pressing of fixture block 060
The position that vehicle needle is compressed.
As shown in Figures 1 to 6, as further optimization, gasket 030 is interference fitted with end cap 040.Gasket 030 and end
Interference fit between lid 040 can make whole device ensure good globality, and button 010, elasticity are realized by end cap 040
The stabilization of mutual alignment relation between element 020 and gasket 030 ensures good overall stability, realizes the process of using
Middle vehicle needle stablizes rotation, avoids damaging patient.
Use process：
As shown in figure 3, button 010 by power effect downward push when, the baroclinic block 011 of button 010 will
It is pressed in above the slanting baffle 061 of fixture block 060, fixture block 060, will be to remote when by the pressing force of the baroclinic block 011 of button 010
Side movement from 050 axle center of gear shaft, makes part and the clamping trolley needle of the bearing column endoporus that is embedded into inside gear shaft 050
Part will move in the same direction, and vehicle needle can be extracted smoothly from the bearing column endoporus of gear shaft 050 at this time；When button 010 not
When stress, under the elastic force effect of elastic element 020, button 010 writes briquetting 011 and can be located above and leave the oblique of fixture block 060
The position of baffle 061, fixture block 060 abut against the outer ring of gear shaft 050, wherein clamping trolley under the elastic force of split circlip 070
The part of needle can be embedded into inside the endoporus of bearing column, tightly clamp vehicle needle, so that vehicle needle is revolved with the movement of dental handpiece
High speed rotary motion is transferred to, realizes treatment and diagnosis to oral cavity.
The utility model structure design is exquisite rationally, has carried out great simplification to the handling steps of vehicle needle, has reduced simultaneously
The difficulty of head processing, has saved processing cost, under the premise of ensureing head upper bearing (metal) column precision, is effectively guaranteed vehicle
The assembly precision of needle, and then meet the required precision of vehicle needle rotation, ensure that precision and the safety of operation, the handling of vehicle needle expend
Time shortening, while improving the working efficiency of doctor, there are good economic results in society.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
