Detailed description of the invention
Below only with embodiment, the enforcement aspect that the utility model is possible is described, but not in order to limit this realityWith the category of novel wish protection, first give chat bright.
Refer to Fig. 1, the clamping device of the dental handpiece that those shown provides for the utility model, it is located at oneIn dental handpiece (dentalhandpiece) (not shown), this clamping device include a positioning tube 4,A connection piece and a control piece 2, wherein this connector is in order to clamp various dental tools, for example drill point (burr)Or grind first-classly, and this control piece 2 produces clamping or unclamps the moving of dental tool in order to control this connectorDo. Each portion member as detailed below it.
As shown in Figure 1 and Figure 2, this positioning tube 4 is a hollow straight tube, and this connector is located at this positioning tubeIn 4. This connector is the collet chuck 1 (chuck) of a formation hollow tube-shape, and inside has one for various teethThe space that section's instrument wears. One end of this collet chuck 1 is defined as a driven end 11, wherein this driven end 11Be concaved with a profile groove 12 extending along this collet chuck 1, make by this this driven end 11 be formed with two and be relativeFolder portion 13. Due to the existence of this profile groove 12, between two folder portions 13, be formed with a gap, make two foldersPortion 13 can produce the beat a little with respect to this collet chuck 1 in the time being subject to External Force Acting, uses the two folder portions of variationDistance between 13; When wherein two folder portions 13 are not yet subject to External Force Acting, it can geometrical clamp be pulled and is arranged inDental tool (not shown) in this collet chuck 1, and two folder portions 13 are subject to External Force Acting and beat outwardlyTime, two folder portions 13 mutually away from, and then unclamp dental tool.
Further define, the top of two folder portions 13 has respectively an end face 131, and two folder portions 13 have respectively first side 132 in the face of this profile groove 12.
On the other hand, as shown in Figure 1 to Figure 3, this control piece 2 has a cylinder body 21, its endEnd stretches out two and is relative pushing and pressing part 22; Wherein two pushing and pressing parts 22 lay respectively at this body 21 bottomsBoth sides, and form the tip-angled shape of taper in width towards its end. This control piece 2 is located in this positioning tube 4,And with the above-mentioned corresponding setting of collet chuck 1; Thin speech, this control piece 2 stretches into this profile groove with two pushing and pressing parts 2212, and be connected in two folder portions 13. Further define, establish respectively the both sides of each pushing and pressing part 22Have one second side 221, and each pushing and pressing part 22 is connected to one to one with its two second side 221On the first side 132 of two folder portions 13.
And this control piece 2 or each folder portion 13 are wherein provided with one at least one contact-making surface connecting at itTungsten carbide coating (tungstencarbidecoating or title wolframcarbidecoating, be called for short WCC),Use the hardness and the wearability that improve contact-making surface. In the present embodiment, of the each folder portion 13 of this collet chuck 1One side 132 is provided with tungsten carbide coating (not shown), and each pushing and pressing part 22 of this control piece 2Two second sides 221 on be also provided with tungsten carbide coating (not shown). In addition each folder portion 13,The periphery anchor ring 211 of the body 21 of end face 131 and this control piece 2 is also provided with tungsten carbide coating (figureIn do not show).
By said structure, the utility model is assembled in the state person as shown in Figure 4 in dental handpiece. WhereinIn the head 31 (head) of dental handpiece 3, be provided with a pneumatic tumbler 33, and this positioning tube 4Be fixed on this tumbler 33, and dental tool 5 is arranged in this collet chuck 1, and solid with two folder portions 13Clamp is pulled it, drives this positioning tube 4 to rotate, and then drive dental tool 5 to see through this tumbler 33Rotate, implement by this diagnosis and treatment operation.
Moreover this head 31 is provided with a button 32, this button 32 is connected in this control piece 2, in order to do confessionUser drives this control piece 2 to move down through pressing this button 32. Accordingly, when this button 32Pressed and after this control piece 2 is moved, as shown in Figure 5, due to the shape of this pushing and pressing part 22, madeTwo folder portions 13 of this collet chuck 1 are subject to this pushing and pressing part 22 and push and open towards both sides, so that two folder portions 13Mutually away from, and then unclamp dental tool 5.
In above-mentioned use procedure, two pushing and pressing parts 22 of this control piece 2 and two folder portions 1 of this collet chuck 1Between 3, can form and be in contact with one another and the state of relative sliding, but in the utility model, be located at above-mentioned portionThe tungsten carbide coating of position, by hardness and the wearability of strengthening contact-making surface, is used and is reduced friction loss, and and then producesRaw effect increasing the service life.
