The first binding ring 120 and the second binding ring 130 are opened.
In this embodiment, the other side of the opening 184 of the first receiving portion 180 on the other side of the first binding member 118A is closed. Further, the front side of the opening 194 of the second receiving portion 190 on the near side of the second binding member 118B is closed. Therefore, the far side end of the shaft portion 200 is prevented from being pulled out by the first receiving portion 180 on the far side, and the near side end of the shaft portion 200 is prevented from being pulled out by the second receiving portion 190 on the near side.

The outer peripheral portion of the base portion 120a of the half ring 120A and the outer peripheral portion of the base portion 130a of the half ring 130A are formed at the same position as the lower portion of the connecting portion 114 so that the lower portion thereof is positioned. The outside of the part 180 and the outside of the second receiving part 190 are formed so that the upper part thereof is located at the same position as the lower part of the connecting part 114.
In this embodiment, the first receiving portion 180 of the shaft portion 116 has the opening 184 in contact with the outer peripheral portion of the half ring 120A, and the second receiving portion 190 of the shaft portion 116 has the opening 194 having a half ring.

  The width (in the width direction) of the connecting portion 114 is less than or equal to half the width (in the width direction) of the first receiving portion 180 of the shaft portion 116 or the second receiving portion 190 of the shaft portion 116. This is because the combined width of the first connecting portion 150 and the second connecting portion 160 is equal to or equal to the width of the first receiving portion 180 of the shaft portion 116 and the second receiving portion 190 of the shaft portion 116. The reason for the following is to change the leaf 18 360 degrees so that the front surface and the back surface of the leaf 18 can be brought into contact with each other with relatively little space between the shaft portions 116.

The first accommodating portion 182 of the first binding member 118A existing around the center of the first connecting portion 150 and the second accommodating portion 192 of the second binding member 118B existing around the center of the second connecting portion 160. An elastic member 202 that applies tension (tensile force or compressive force) in the longitudinal direction of the shaft portion 200 is interposed therebetween in a compressed state. The elastic member 202 is formed by a coil spring formed by winding a steel wire in a coil shape, and the shaft portion 200 is inserted into a ring of a cylindrical coil spring.
The elastic member 202 has a far side end in contact with a near side end of the second receiving part 190 of the second binding member 118B, and a near side end of the first receiving part 180 of the first binding member 118A. The first binding member 118 </ b> A is pushed down toward the near side and the second binding member 118 </ b> B is pushed up by the restoring force (uniform) in contact with the far side end.
Thus, when the binding portion 112 is closed, the elastic member 202 is in a direction to engage the binding portion 122 of the first binding ring and the binding portion 132 of the second binding ring. It is working.
When the pressing portion 240 is pushed with a finger, the elastic force of the elastic member 202 is increased when the locked ring-locking portion 122 of the locked first ring and the fixed-ring portion 132 of the second binding ring are removed. Accordingly, the first binding ring 120 of the first binding tool member 118A is moved to the other side, and the second binding ring 130 of the second binding tool member 118B is moved to the front side to close the first binding ring 120 that has been closed. And the second ring 130 are opened.

The resilient member 202 is formed of a torsion coil spring, and is linear with a linear first fixed tip 202b extending from both ends of the winding 202a and the winding 202a in a direction orthogonal to or intersecting with the central axis of the winding 202a. The original state in which the second fixed tip 202c is continuously provided and no torsional moment is generated is that the first fixed tip 202b and the second fixed tip 202c protrude in a tangential direction outside the winding portion 202a. Has been.
A support portion 150a and a support portion 160a are formed on the connecting portion 114 in order to support tip portions extending from both ends of the winding portion 202a of the elastic member 202.
A fixed front end portion extending from both ends of the winding portion 202a of the elastic member 202 has a support portion 150a formed on the first connecting portion 150 of the first binding member 118A, and a second binding facing the support portion 150a. It is locked and supported by the support portion 160a of the second connecting portion 160 of the tool member 118B.
That is, one first fixed distal end portion 202b is supported by the support portion 150a of the first connecting portion 150, and the other second fixed distal end portion 202c is second so as to face the first fixed distal end portion 202b. It is supported by the support part 160 a of the connecting part 160.
By pressing the pressing portion 240 with a finger, the unlocking portion 122 of the first binding ring and the binding portion 132 of the second binding ring that are locked are on the side opposite to the moving direction. The first fixed tip portion 202b is supported by the support portion 150a of the first connection portion 150, and the other second fixed tip portion 202c is supported by the support portion 160a of the second connection portion 160 on the opposite side to the moving direction. It is supported.
One fixed tip 202b and the other fixed tip 202c were originally open, but when the first binding ring 120 and the second binding ring 130 are in a closed state, they are in an originally open state. The first fixed distal end portion 202b and the second fixed distal end portion 202c, which are brought close to parallel from each other, are supported by the support portion 150a and the support portion 160a of the connecting portion 114. That is, the elastic member 202 has a first fixed tip 202b locked to the support 150a of the first connecting portion 150 and a second fixed tip 202c locked to the support 160a of the second connecting portion 160. It becomes twisted.

The elastic member 202 has a far side end in contact with a near side end of the second receiving part 190 of the second binding member 118B, and a near side end of the first receiving part 180 of the first binding member 118A. The first binding member 118 </ b> A is pushed down toward the near side and the second binding member 118 </ b> B is pushed up by the restoring force (uniform) in contact with the far side end.
Thus, when the binding portion 112 is closed, the elastic member 202 is in a direction to engage the binding portion 122 of the first binding ring and the binding portion 132 of the second binding ring. It is working.
When the pressing portion 240 is pushed with a finger, the elastic force of the elastic member 202 is increased when the locked ring-locking portion 122 of the locked first ring and the fixed-ring portion 132 of the second binding ring are removed. Accordingly, the first binding ring 120 of the first binding member 118A is moved to the other side, and the closed first binding ring 120 and second binding ring 130 are opened.
When the pressing portion 240 is pushed with a finger and the first connecting portion 150 of the first binding member 118A is relatively moved, the first connecting portion 150 and the second connecting portion 160 cause the elastic member 202 to return to the original state. Rotation in the rotation direction is caused by the force acting so that one first fixed tip 202b and the other second fixed tip 202c rotate in the rotation direction to open the ring portion 112.
Thus, in this embodiment, the engagement of the first binding ring locking portion 122 of the first binding ring 120 and the binding ring locking portion 132 of the second binding ring of the second binding ring 130 is engaged. When released, the first binding ring 120 and the first connecting part 150 are acted upon by a force acting to separate one of the first fixed tip 202b and the other second fixed tip 202c in the circumferential direction.
