Here, the supporting end rotational axis 1a can be set along the direction in which the supporting end portion 1 exactly faces the pressing end portion 2, but the present invention is not limited thereto. The supporting end portion 1 may be somewhat different from the pressing end portion 2 Or may be set along the oblique facing direction.

The connecting relationship between the supporting end 1 and the operating mechanism 3 will be described below as an example.

1 shows an embodiment of the present invention in which a connecting portion 31 and a shaft unit 33 corresponding to the distal end portion 111 of the supporting end portion 1 and a connecting portion 31 corresponding to the distal end portion 211 of the pressing end portion 2 31 and a shaft unit 33 are shown. Referring to Fig. 1, the operating mechanism 3 may include a connecting portion 31 and a shaft unit 33 corresponding to the distal end 111 of the supporting end 1.

The shaft unit 33 corresponding to the support end 1 has a first protruding member 311 and a second protruding member 311. The shaft unit 33 corresponds to the end portion 1 of the support end 1 interposed between the first protruding member 311 and the second protruding member 312. [ (111), and the second protruding member (312).

In other words, in a state in which the distal end portion 111 of the support end portion 1 is interposed between the first projecting member 311 and the second projecting member 312, the shaft unit 33 is supported by the first projecting member 311, May be arranged to sequentially traverse the distal end (111) and the second projecting member (312) of the support end (1).

1, 3A, and 3B, the shaft unit 33 may include a rotatable shaft portion 331 that allows rotation of the support end 1. In addition, the shaft unit 33 may include a rotation-restricted shaft portion 332 that limits the rotation of the support end 1. The rotation-limiting shaft portion 332 can be connected to the rotation-allowing shaft portion 331.

1, the hole 311a formed in the first projecting member 311 may have a cross section corresponding to the rotation allowable shaft portion 331 so that the shaft unit 33 crosses. The hole 111a formed in the distal end portion 111 of the support end portion 1 may have a cross section corresponding to the rotation restricting shaft portion 332 so that the shaft unit 33 is traversed. The hole 312a formed in the second projection member 312 may have a cross section corresponding to the rotation limiting shaft portion 332 so that the shaft unit 33 traverses.

Illustratively, referring to FIG. 1, the cross section of the rotatable shaft portion 331 may be circular. According to this configuration, the cross section of the tilting shaft portion 331 is circular and the hole 311a formed in the first projecting member 311 may have a circular hole shape corresponding to this circular cross section.

However, the circular section of the rotatable shaft portion 331 may include a shape in which the circular section is slightly deformed, for example, a shape in which a groove is formed in the middle of the circumference of the circular section. That is, it is desirable to understand in the broad sense that the circular cross section is a cross section including arc shapes that enable rotation when engaged with a circular hole.

The end face of the rotation-limiting shaft portion 332 may be formed in various shapes such that the rotation of the rotation-limiting shaft portion 332 may be restricted when the shaft is engaged with the hole having the shape corresponding thereto at a predetermined angle . As an example, the cross-section of the rotation-limiting shaft portion 332 may be a figure in which a predetermined pattern is repeated along the circumferential direction.

For example, referring to FIG. 1, the cross-section of the rotation-limiting shaft portion 332 may be an angular gear-like shape. In other words, the end surface of the rotation-limiting shaft portion 332 may be a figure in which a sharp sawtooth pattern is repeatedly formed along the circumferential direction.

That is, the rotation restricting shaft portion 332 has a cross section of a figure in which a predetermined pattern is repeated along the circumferential direction, and the hole 111a or the second projecting member 312 formed in the distal end portion 111 of the support end portion 1, The rotation limiting shaft portion 332 can be restricted in its rotation.

1, 3A, and 3B, the shaft unit 33 may include an elastic member 333. The elastic member 333 elastically moves the shaft unit 33 to the rotation permitting state (see FIG. 3B) when the external pressure is applied, and rotates the shaft unit 33 in the rotation restricting state 3a (elastic recovery). Illustratively, the elastic member 333 may be a spring or a leaf spring.

Further, the shaft unit 33 may include a fixing member 334. [ The fixing member 334 is configured to fix the shaft unit 33 so as to be movable between the rotation permitting state and the rotation limiting state. Referring to Figs. 1, 3A, and 3B illustratively, an elastic member 333 may be interposed between the head portion of the fixing member 334 and the side surface of the first projecting member 311. For example, the fastening member 334 may be configured as a bolt with threads. 3A and 3B, a circumferential fixing unit 335 may be provided on the opposite side of the fixing member 334 in the shaft unit 33 to prevent the shaft unit 33 from coming off.

That is, the distal end of the pressing end portion 2 may be provided in a bent shape such that the distal end of the pressing end portion 2 is brought into contact with the other side of the teeth 500 when the present extraction forceps is rotated to more effectively press the teeth 500,

The pressing end 2 can be connected to the operating mechanism 3 so that the direction opposite to the supporting end 1 can be rotated or fixed at a predetermined rotation angle with the pressing end rotary shaft 2a. Here, the pressing end shafts 2a can be set along the direction in which the pressing end portion 2 is opposed to the supporting end portion 1 exactly, but the present invention is not limited thereto, and the pressing end portion 2 may be somewhat different from the supporting end portion 1 Or may be set along the oblique facing direction.

The connecting relationship between the pressing end 2 and the operating mechanism 3 will be described below as an example.
