Claims

[Claims for Utility Model Registration] 1. A holder body 2 having a coupling portion 21 for the vibration source 11 of the handpiece body 1 at the rear end, and a holder body 2 that is slidably fitted into the holder body 2 along its axial direction. A vibrating tool that is tightly held by the tool fixing member 3 mounted therein, an elastic body 4 that elastically biases the fixing member 3 in the axial direction, the fixing member 3 that has obtained this biasing force, and the holder main body 2. A dental vibrating tool attachment/detachment device consisting of 5. 2 The holder main body 2 and/or the fixing member 3
The attachment/detachment device according to claim 1, wherein a tool holding hole 22 and/or 31 that intersects the axis of the attachment/detachment device is provided. 3. The attaching/detaching device according to claim 1 or 2, wherein the inner diameter of the tool holding hole 22 and/or 31 is slightly larger than the outer diameter of the shank portion 51 of the vibrating tool 5. 4. Request for utility model registration in which tool holding grooves 23 and 32 intersecting the axes of the holder main body 2 and fixing member 3 are provided in opposing relation so as to jointly hold the shank portion 51 of the vibrating tool 5. The attachment/detachment device according to item 1. 5. The attachment/detachment device according to claim 1, wherein the fixing member 3 is installed inside the holder main body 2. 6. The attachment/detachment device according to claim 1, wherein the fixing member 3 is externally mounted on the holder main body 2. 7. The attachment/detachment device according to claim 1, wherein the elastic body 4 is selected from a tension spring, a compression spring, and a rubber elastic body. 8. The attaching/detaching device according to claim 1, wherein the holder main body 2 has a fluid supply conduit 6 and its spout 61. 9. The attachment/detachment device according to claim 1, wherein the fixing member 3 has a means 7 for preventing extraction from the holder main body 2. 10. The attachment/detachment device according to claim 1 or 7, wherein a sealing member 8 is interposed between the fixing member 3 and the holder main body 2. 11. The attaching/detaching device according to claim 1, wherein a cross section of the shank portion 51 of the vibrating tool 5 includes a corner portion.
