In addition, as the guide protrusion 2116 is positioned higher than the support protrusion 2114 as shown, the gap between the elastic fixing portion 222 and the elastic catching portion 224 of the cap spring 220 is widened.

In this case, as shown, the elastic fixing portion 222 is subjected to the maximum opening force by the guide protrusion 2116, the elastic locking portion 224 elastically connected to the elastic fixing portion 222 by this action ) Is temporarily opened and the locking control of the locking projection 225 of the elastic locking portion 224, which was caught in the locking groove 2119 of the body 210, is temporarily released.

This action is useful when the cap spring 220 is dropped from the body 210. For example, if the locking protrusion 225 is held in the locking groove 2119 when the ligation protrusion 225 is ligated or dropped. It may not be easily made by interfering with ligation or dropping action by the locking state, and in some cases may cause a problem that the locking protrusion 225 may be damaged to lose the function.

6D illustrates a state in which the cap spring 220 is inserted into the body 210.

That is, the outer peripheral surface of the guide protrusion 2116 of the body 210 and the inner peripheral surface of the connecting portion 226 of the cap spring 220 is pushed in close contact.

In this case, the elastic fixing part 222, which is opened to the maximum by the guide protrusion 2116, is closed by the elastic restoring force, and the bending part 223 is inserted into the fixing groove 2113 formed in the fixing protrusion 2112.

At this time, since the connection portion 226 of the cap spring 220 in close contact with the body 210 is formed in a 'C' shape, it is not opened by the guide protrusion 2116.

6E is a state in which the cap spring 220 is finally ligated to the body 210.

This, the cap spring 220 is completely in close contact with the body 210 is a state in which the elastic fixing portion 222 and the elastic catching portion 224 mutually retracted as shown by its elastic restoring force.

7 is a state diagram to drop the cap spring 220 in the body 210 according to the first embodiment of the present invention, Figure 8 is a state diagram to drop the body 210 from the teeth according to the first embodiment of the present invention. As a look at the state to drop the bracket from the tooth with reference to this.

At this time, both parts of the body 210 which the tool bites are greatly shaken, and relatively the center is less shaken.

Thus, the peripheral portion 2126 of the attachment portion 2120 is first dropped from the tooth.

In addition, the central portion 2124 having a relatively small amount of adhesive applied to the peripheral portion 2126 may be removed from the tooth even if it is relatively weakly shaken than a force for shaking the peripheral portion 2126.

That is, in the related art, since the attachment surface is flat, any section of the attachment surface has the same adhesive strength, and thus the center is attached even when both ends of the body are removed first during the removal of the body. If you pick up more power, the body will fall off.

In this case, as the center of the tooth and the body is eliminated, the enamel layer of the tooth is also eliminated, thereby causing a secondary problem of damaging the tooth.

On the other hand, a plurality of protrusions 118 having the same surface as the surface of the attachment surface 110 is formed in the receiving space 112, that is, the central portion 114 and the peripheral portion 116, the adhesive 118 Even if it is not applied or even if diarrhea is applied, the adhesive force is insignificant, so when the body 210 is removed, as the force to shake the body 210 with a tool as shown in the figure acts the same around the protrusion 2128 As a result, the body 210 can be easily detached from the tooth with little force.
