JP6296705B2 - Connecting tool for pincer used by hand - Google Patents

Description

  The present invention relates to a connecting tool for constituting a pincer used by hands such as chopsticks, tweezers, and tongues.

  A pincer that is composed of a pair of pinching members, such as chopsticks, tweezers, and tongs, and is used by hand is a tool for a person who effectively uses the functions of a human hand. In this case, the “clamping member” is an individual member as shown in FIG. 4 if it is chopsticks, and if it is tweezers, it is an independent member. Further, the “pinching member” for the tongue is a fork or a spoon as shown in FIG.

  By the way, this kind of pincer is a convenient tool for those who have sufficient hand functions, but it is hard to use for those who are unfamiliar with its use, for example, infants and people with limited hands. . In particular, the two “clamping members” cannot pinch the object unless the tips of the two “clamping members” are properly opposed to both sides of the object.

  As described above, various tools have been proposed in Patent Documents 1 to 4 that can reliably perform a pinching operation while using two “pinching members”.

  The “chopstick holder” proposed in Patent Document 1 was made for the purpose of “supporting the use of chopsticks by attaching an existing chopstick to the chopstick holder” and is shown in FIG. Thus, “the chopsticks 3 are attached to the circular holding portions 1 at both ends of the elastic body portion 2 for use”, and it is considered that the above object can be achieved.

  However, the “chopstick holder” of this patent document 1 has an “elastic body portion 2 and round holding portions 1 at both ends thereof” which are large and open. It seems that the part protrudes from the hand and is difficult to use.

  In addition, the “holding rod correction assisting tool” proposed in Patent Document 2 is “a very simple configuration and is inexpensive and has a conventional holding correction rod and holding correction tool”. As in FIG. 11, the object of the present invention is to provide a tool for correcting the holding of the gripped rod that can be easily corrected. As shown in FIG. In combination with the tubular spacer 12, a pair of small rings 11a and 11a are formed by which rubber bands protruding from the openings at both ends of the tubular spacer 12 can be attached to the chopsticks 5a and 5b, respectively. Is.

  However, the “supporting tool for holding the gripped rod” of Patent Document 2 is the same as that of Patent Document 1 described above unless the length of the “tubular spacer 12” matches the size of the hand of the user. In addition, it is thought that it becomes difficult to use by people.

  Further, the “chopstick assisting tool and elastic member” of Patent Document 3 was made for the purpose of “obtaining a chopstick assisting tool having an elastic member that can be detachably attached”. As shown in FIG. The rear ends of 11a and 11b are rotatably connected by a connecting member 12, and an elastic member 14 is detachably inserted into an intermediate portion of the chopsticks 11a, which opens the two chopsticks 11a and 11b. In order to make it separate, it is made of a synthetic rubber or a synthetic resin material having elasticity, and the chopsticks 11a are attached to the insertion hole 14a, and the semicircular arc-shaped resilient portion 14b provided inside and adjacent to the insertion hole 14a. The tip is in contact with the chopsticks 11b. "

  However, since the “chopstick assisting tool and elastic member” of Patent Document 3 is used to stop the chopsticks with the elastic member 14 or the holder 13 shown in FIG. 12, the portion of the holder 13 or the elastic member 14 where the chopsticks are inserted is inserted. The shape of chopsticks that can be used is limited depending on the size, and it cannot be used for other tweezers or tongs.

  And, the “chopstick holder” in Patent Document 4 says, “When used by an extremely handicapped person or an infant or foreigner who uses it to grip chopsticks, the torsional force is greater than the elastic body that holds the chopsticks. When it is added to chopsticks, it was made for the purpose of solving the problem of chopstick tips not being prepared and not being able to pick food. As shown in FIG. The upper part of 10 is sandwiched between two flat plates 2 and 3 by the force of an elastic body or rubber band 6, and the increase in the gap generated between the chopsticks 10 and the two plates 2 and 3 is limited. A configuration including a gap limiting mechanism ”.

  However, the “chopstick holder” in Patent Document 4 is “having a gap limiting mechanism that limits an increase in the gap generated between the chopstick 10 and the two plates 2 and 3”. It is thought that the “use of the chopsticks” is limited by the “mechanism” and the usability becomes worse.

  Accordingly, the present inventors can connect a pair of pinching members for constituting a pincer used by hands such as chopsticks, tweezers, and tongs with a very simple structure. The present invention has been completed as a result of various studies on how to make it possible to be used by people who are unfamiliar with its use, infants, and handicapped people.

  That is, the object of the present invention is that a pair of pinching members can be connected, and pinching tools such as chopsticks, tweezers and tongs, regardless of their types and shapes, The object of the present invention is to provide a connecting device that can be used by an infant or a handicapped person with a simple structure.

In order to solve the above problems, the means taken by the present invention will be described with reference numerals used in the description of embodiments described later.
“A pair of sandwiching members 21, 21 is a set, and the sandwiching tool 20 that is used to hold the entire sandwiching member 21, 21 by hand and sandwich an object with the action portion 22 of each sandwiching member 21, a communication Huyghe 10 connecting the member 21 to each other,
Are integrally formed by a resilient material, a pair of the body 11, 11 that have a insertion hole 12 of the least two places also the pinching member 21 is inserted, the pair of main body 11, And a holder 14 having an insertion hole 14a into which 11 is inserted.
By moving the holder 14 on the stacked main bodies 11 and 11, the amount of protrusion of both the main bodies 11 and 11 from both sides of the holder 14 can be changed so that the opening angle of each sandwiching member 21 can be adjusted. Connecting device 10 "characterized by
It is.

  As shown in FIGS. 7 to 10, the connector 10 according to the present invention includes a main body 11, 11 having an insertion hole 12, and a holder 14 having an insertion hole 14 a into which the pair of main bodies 11, 11 are inserted. The amount of protrusion of both the main bodies 11 and 11 from both sides of the holder 14 is changed by moving the holder 14 on the stacked main bodies 11 and 11, and the opening angle of each sandwiching member 21 is changed. Although it can be adjusted, before explaining this, it demonstrates from the connector 10 which this inventor first developed.

  As shown in FIG. 1 (a), the connecting tool 10 first developed by the present inventor is a pair of sandwiching members 21 and 21, and is used as a pair of sandwiching members 21 and 21 so as to sandwich an object by hand. 20 (in the example of FIG. 1, chopsticks are assumed as the sandwiching tool 20) for connecting a pair of sandwiching members 21 constituting the sandwiching tool 21 as shown in FIG. Is. The example shown in FIG. 1A shows that the connector 10 can be used as a “chopstick rest”.

  FIG. 5 illustrates a case where tweezers separated from each other at the end portion 23 are configured as a pair of sandwiching members 21. In FIG. 6, one sandwiching member 21 is a spoon and the other sandwiching member. An example is shown in which a so-called “tongue” is formed by connecting 21 with a fork 21 with a connector 10.

  Now, each of the main bodies 11 constituting the connector 10 developed by the present inventor is as shown in FIG. 2, for example, and is integrally formed by an elastic material such as a synthetic resin or a metal plate. Formed. As shown in FIG. 2 (c), for example, the main body 11 is adopted as a pair. The main body 11 is attached to each other and connected by an adhesive or a screw at each connecting portion 13. Is.

  Each main body 11 is formed with at least two insertion holes 12 located on both sides of the connecting portion 13. The term “at least two places” means that one place on one side of the connecting portion 13 and two places on the other side may be provided, and a plurality of places may be formed on both sides of the connecting portion 13. Moreover, the size of each insertion hole 12 should just be able to insert each clamping member 21 for comprising the clamping tool 20, and even if the whole clamping member 21 can be extracted completely, It may be one that can only be inserted halfway.

  As illustrated in FIG. 3, the action portions 22 or the end portions 23 of the respective pinching members 21 are inserted into these insertion holes 12, but the manner of insertion is important. That is, as shown in FIG. 3, first, the action portion 22 of the sandwiching member 21 is inserted into the insertion hole 12 from the back side (between the main bodies 11 overlapping each other), and then the other insertion is performed. It inserts into the hole 12 from the front side (side which is the surface of each main body 11). As a result, each main body 11 bends in a “bow” shape centering on the connecting portion 13 as shown in FIG. 1B and FIG. The pinching member 21 is elastically supported. This is because each main body 11 at this time is integrally formed of an elastic material such as a synthetic resin or a metal plate and bent into a bow shape.

  In other words, each main body 11 is integrally formed of a resilient material such as a synthetic resin or a metal plate. Therefore, when placed in a natural state, each main body 11 is shown in FIGS. As shown in (), it becomes a straight and flat plate. And if the pinching member 21 which comprises the pinching tool 20 as mentioned above is inserted in each insertion hole 12, the state which incorporated the force which tries to return to flatness by own elastic force (state with internal stress) Thus, each sandwiching member 21 is supported. At this time, the contact edge 12a of the insertion hole 12 into which each pinching member 21 is inserted, which is opposite to the connecting portion 13, presses the corresponding surface of each pinching member 21. Is held without changing its position relative to the connector 10.

  In this case, if the shape of the insertion hole 12 into which each pinching member 21 is inserted is “circle”, “ellipse”, “square”, “diamond”, or “triangle”, The surface of the pinching member 21 comes into contact with many points or partial arcs, and the pinching members 21 are stably connected. Therefore, each pinching member 21 is held without changing its position with respect to the connector 10 and without being easily rotated.

  Moreover, when the connection part 13 is provided in the center of the said connection tool 10, in the distance from the center of the connection part 13 to each insertion hole 12 in each main body 11, or the part in the right and left of the connection part 13 of each main body 11. The internal stress is the same. For this reason, each pinching member 21 connected by the said connecting tool 10 is supported in the mutually substantially parallel state.

  Therefore, in order to grasp something, the user holds the pinching tool 20 composed of a pair of pinching members 21. The pinching tool 20 holds each pinching member 21 by the connecting tool 10. Therefore, even if only one pinching member 21 or the connecting tool 10 is lifted, the entire structure can be lifted, and at least the connecting tool 10 is sized to fit between the thumb and another finger. Can be picked up immediately with one hand.

  Now, in order to grasp an object with the pinching tool 20 put in the hand together with the connecting tool 10 developed by the present inventor, the same operation as using a chopstick may be performed. In the example of FIG. 1B, the operation of narrowing the action portion 22 of each pinching member 21 is performed using the finger force that resists the elastic force of each main body 11. At this time, the center line of each insertion hole 12 in each main body 11 coincides with the axis line of the corresponding pinching member 21, and the axis lines in each main body 11 are maintained parallel to each other by the connector 10. Therefore, the constricted action portions 22 of the respective pinching members 21 come into contact with each other. That is, an object between the narrowed working portions 22 can be easily grasped by the pinching tool 20 connected by the connecting tool 10.

  For example, if the force applied to each pinching member 21 is loosened after putting the object grasped by each action part 22 in the mouth, each pinching member 21 is caused by the elastic force of the main body 11 in the connector 10. Returning to the state shown in FIG. 1 (b), the object grasped or pinched can be released into the mouth.

  The above operation is the same in the case of the pinching tool 20 as the tweezers shown in FIG. 5 and in the case of the tongue shown in FIG. The clip tool 20 connected by the connector 10 can be easily used by any person who is unfamiliar with the use of chopsticks, tweezers or tongs, or by an infant or a handicapped person. is there.

  As described above, the connecting tool 10 developed by the present inventor can connect a pair of pinching members 21, and the pinching tool 20 such as chopsticks, tweezers and tongs, regardless of the type or shape thereof, It can be used by people who are unfamiliar with its use, infants and handicapped people, and has a simple structure.

  By the way, about the coupling tool 10 developed initially, the connection part 13 formed in each main body 11 is formed in the position where the distance with one insertion hole 12 becomes shorter than the distance with the other insertion hole 12. There was also. That is, in the first coupling tool 10, as shown in FIG. 2A and FIG. 3, the distance between the coupling portion 13 and one insertion hole 12 is shorter than the distance from the other insertion hole 12. It was sometimes formed in the position.

  More specifically, as shown in FIG. 3, the connecting portion 13 is formed at a position where the distance L1 to the insertion hole 12 on the right side of the drawing is shorter than the distance L2 to the insertion hole 12 on the left side of the drawing. And in each main body 11 of the connector 10 shown in FIG. 3, the length from the connection part 13 to the insertion hole 12 is short in the right side part.

  Each main body 11 is formed of an elastic material, and when the connector 10 is used, both side portions of the connecting portion 13 are bent as shown in FIG. If the part is long or short, the internal stress inherent in the shorter part becomes stronger than that inherent in the longer part. Therefore, in the example of FIG. 3 for explaining the case of chopsticks, when the connecting tool 10 connecting both the holding members 21 is in a natural state, the end 23 of each holding member 21 connected by the connecting tool 10. A force is applied so that the sides come into contact with each other, and both action portions 22 which are the tips of the respective pinching members 21 are in an open state.

  In other words, in the first connector 10, when the pair of pinching members 21 are connected by the connector 10, the action portion 22 is in an open state, and preparations for gripping or pinching an object have already been made. It will be. For this reason, the pinching tool 20 formed by connecting the pinching members 21 with the connecting tool 10 is configured so that an object sandwiched by the hand enters between the action portions 22 so that the pinching members 21 are placed on the thumbs. If you hold it with other fingers, you can pinch it naturally.

  Furthermore, with respect to the coupling tool 10 that was first developed, for each insertion hole 12, at least the shape of the contact portion 12a on the opposite side of the coupling portion 13 is the cross-sectional shape perpendicular to the longitudinal direction of the sandwiching member 21. The same was done.

  When both the pinching members 21 are connected using the connecting tool 10, a part of the pinching member 21 abuts at least the inner edge on the opposite side of the connecting portion 13 in each insertion hole 12. This is described above with reference to FIG. Of course, for each insertion hole 12, a part of the sandwiching member 21 may also come into contact with the inner edge on the connecting portion 13 side, but this case also includes the meaning of “at least”. The abutting member 21 abuts on the abutting edge 12a shown in FIG. 2A. If the shape of the abutting edge 12a is the same as the outer shape of the sandwiching member 21, that is, each If the shape of the cross section orthogonal to the longitudinal direction of the pinching member 21 is the same, as shown in FIG. 4, the contact edge 12a has a wide area (long line) on the outer surface of the pinching member 21 or a plurality of points. Will abut.

  If the contact edge 12a of each insertion hole 12 contacts the outer surface of the corresponding pinching member 21 at a wide area, a long line, or a plurality of points as shown in FIG. A detent will be made. Particularly, the portion that becomes the handle of the flat pinching member 21 that constitutes the tweezers shown in FIG. 5 and the handle of the spoon or fork that constitutes the tongue shown in FIG. If it is the part which becomes, the action part 22 of each clamping member 21 will not turn and become unusable at the time of use of the clamping tool 20. FIG.

  On the other hand, as shown in FIGS. 7 to 10, the connector 10 according to the present invention developed this time includes a holder 14 having an insertion hole 14 a into which the pair of main bodies 11 and 11 described above are inserted. It is what. This holder 14 changes the protrusion amount from both sides of the holder 14 of both the main bodies 11 * 11 when a user moves on the main bodies 11 * 11 which were piled up.

  The movement of the holder 14 may be performed after inserting each pinching member 21 into the insertion hole 12 of each main body 11 or before inserting the pinching member 21 into each insertion hole 12. Also good. This is because the opening angle of each pinching member 21 can be adjusted.

  The action of the holder 14 is similar to the action of the connecting portion 13 formed on each main body 11 with respect to the connecting tool 10 that was first developed as described above. 13 is "fixed" formed at a position where the distance between the two insertion holes 12 is different, whereas the position of the holder 14 relative to each body 11 can be changed according to the user's preference. Is different.

  More specifically, for example, as shown in FIG. 8 (a), the holder 14 is exposed on the right side if it is moved on each main body 11 so that its center line is shifted to the right side in the figure. The distance L1 between the front end of the main body 11 and the center line of the holder 14 is shorter than the distance L2 between the front end of the main body 11 exposed to the left side and the center line of the holder 14. That is, in each main body 11 of the connector 10 shown in FIG. 8A, the portion exposed from the right side of the holder 14 is shorter than that on the left side.

  Each main body 11 is formed of an elastic material, and when the connector 10 is used, the portions exposed on both sides from the holder 14 are bent as shown in FIG. If the two exposed parts are long and short, the internal stress inherent in the shorter part is stronger than that inherent in the longer part. Accordingly, in the example of FIG. 7 for explaining the case of chopsticks, when the connecting tool 10 connecting both the holding members 21 is in a natural state, the end portions 23 of the respective holding members 21 connected by the connecting tool 10 are used. A force is applied so that the sides come into contact with each other, and both action portions 22 which are the tips of the respective pinching members 21 are in an open state.

  In other words, in the connector 10 having the holder 14, if the holder 14 is moved on the main body 11 and is unevenly distributed on the end 23 side of the sandwiching member 21, the pair of sandwiching members 21 are connected to the connector 10. 7 and 9 (b), the action portion 22 is in an open state, and preparations for gripping or pinching an object have already been made. For this reason, the pinching tool 20 formed by connecting the pinching members 21 with the connecting tool 10 is configured so that an object sandwiched by the hand enters between the action portions 22 so that the pinching members 21 are placed on the thumbs. If you hold it with other fingers, you can pinch it naturally.

  Of course, each main body 11 of the connector 10 has a flat plate shape as shown in FIG. 8B and FIGS. 10A and 10B. Can be easily inserted into the insertion hole 14a and moved on both the main bodies 11. Needless to say, when the holder 14 is placed at the center position of the main body 11, the pair of sandwiching members 21 are parallel to each other, for example, as shown in FIG.

  Therefore, the connecting tool 10 according to the present invention can connect a pair of pinching members 21, and the pinching tool 20 such as chopsticks, tweezers, and tongs can be used by a person who is unfamiliar with its use regardless of its type or shape. It can also be used by infants and handicapped people, and the holder 14 itself can be moved on the main body 11 easily according to the user's preference, and has a simple structure. is there.

As described above, in the present invention,
“A pair of sandwiching members 21, 21 is a set, and the sandwiching tool 20 that is used to hold the entire sandwiching member 21, 21 by hand and sandwich an object with the action portion 22 of each sandwiching member 21, a communication Huyghe 10 connecting the member 21 to each other,
Are integrally formed by a resilient material, a pair of the body 11, 11 that have a insertion hole 12 of the least two places also the pinching member 21 is inserted, the pair of main body 11, And a holder 14 having an insertion hole 14a into which 11 is inserted.
By moving the holder 14 on the stacked main bodies 11 and 11, the amount of protrusion of both the main bodies 11 and 11 from both sides of the holder 14 can be changed so that the opening angle of each sandwiching member 21 can be adjusted. What I did "
There is a feature in the structure, and by this, a pair of pinching members 21 and 21 can be connected, and the pinching tool 20 such as chopsticks, tweezers and tongs can be used regardless of its type or shape. A simple configuration of the connector 10 that can be used by unfamiliar people, infants, and handicapped people, and that the holder 14 itself can be moved on the main body 11 easily according to the user's preference. It can be provided by.

It is a top view which shows the prior art shown by patent document 3. FIG. It is a top view which shows the prior art shown by patent document 4. FIG.

  First, the connecting tool 10 at the stage before the development of the present invention will be described with reference to FIGS. 1 to 6. FIG. 1 shows a case where a chopstick is assumed as a clip tool 20 composed of a pair of clip members 21. A connector 10 is shown. 5 illustrates a case where tweezers separated from each other at the end 23 are illustrated as the pair of sandwiching members 21, and in FIG. 6, one sandwiching member 21 is a spoon and the other sandwiching member 21. A fork is used as a fork to form a so-called “tongue” by connecting them with a connector 10.

  The connector 10 is made of a material having elasticity such as synthetic resin or metal, and has a pair of main bodies 11 formed in a shape as shown in FIGS. 2 (a) and 2 (b). As shown in FIG. 2 (c), they are configured by integration.

  Each main body 11 is integrally formed of a material having elasticity such as a synthetic resin or metal, and is molded using polyethylene terephthalate or acrylic resin as a material. When the main body 11 is molded, at least two insertion holes 12 and a connecting portion 13 therebetween are also molded.

  The insertion hole 12 formed in each main body 11 may have any shape and any size as long as each pinching member 21 for constituting the pinching tool 20 can be inserted, but at least both sides of the connecting portion 13. One by one is required.

  Further, when the portion of each insertion hole 12 on the end edge side of the main body 11 is a contact edge 12a, the shape of the contact edge 12a is not particularly limited, but the shape of the contact edge 12a is the pinching member 21. If it is made the same as the shape of the cross section orthogonal to the longitudinal direction, the detent of the pinching member 21 is exhibited and the pinch tool 20 can be used more reliably. This is because when both the pinching members 21 are connected using the connecting tool 10, one of the pinching members 21 is placed on the contact edge 12 a in each insertion hole 12, which is mainly opposite to the connecting portion 13. As long as the shape of the cross section perpendicular to the longitudinal direction of each pinching member 21 is the same, for example, as shown in FIG. 4, this abutting edge 12 a is the outer surface of the corresponding pinching member 21. This is because they come into contact with each other at a wide area (long line) or at a plurality of points.

  The connecting portion 13 of this embodiment formed integrally with each main body 11 is formed in a state of protruding from the inner surface side of the main body 11 (the lower side in the drawing in FIG. 2B). When the two main bodies 11 are integrated by the respective connecting portions 13 by projecting the connecting portions 13 from the main bodies 11, as shown in FIG. A gap can be formed. This gap makes it easy to open the two main bodies 11, and when connecting the two pinching members 21 using the connector 10, as shown in FIG. The operation of inserting the pinching member 21 is facilitated. Needless to say, a gap is not necessarily required between the two main bodies 11.

  That is, as illustrated in FIG. 3, the action portion 22 or the end portion 23 of each pinching member 21 is inserted into these insertion holes 12, but first, into one insertion hole 12, The action portion 22 of the pinching member 21 is inserted from the back side (the gap between the main bodies 11), and then inserted into the other insertion hole 12 from the front side of the main body 11. As a result, each main body 11 bends in a “bow” shape centering on the connecting portion 13 as shown in FIG. 1B and FIG. The pinched member 21 is supported elastically. This is because each main body 11 is integrally formed of an elastic material such as a synthetic resin or a metal plate.

  In other words, each main body 11 is integrally formed of a resilient material such as a synthetic resin or a metal plate. Therefore, when placed in a natural state, each main body 11 is shown in FIGS. As shown in (), it becomes a straight and flat plate. And if the pinching member 21 which comprises the pinching tool 20 is inserted in each insertion hole 12 as mentioned above, each pinching member 21 will be supported in the state where the force which tries to return to flatness with its own elastic force was incorporated. It is. At this time, the contact edge 12a of the insertion hole 12 into which each pinching member 21 is inserted, which is opposite to the connecting portion 13, presses the corresponding surface of each pinching member 21. Is held without changing its position relative to the connector 10.

  Of course, in the state where the connecting portions 13 of the main bodies 11 are attached to each other, the connection of the connecting portions 13 is fixed with an adhesive, a screw, or the like, so that both the main bodies 11 can be formed as shown in FIG. As shown in (c), they are integrated into the connector 10. In addition, each connection part 13 does not need to be formed as what protrudes on the main body 11 like this embodiment, and may be a mere screw hole.

  Now, regarding the relationship between each insertion hole 12 and the connecting portion 13 in each main body 11, the distance L1 between the connecting portion 13 and one insertion hole 12 is shorter than the distance L2 between the connecting portion 13 and the other insertion hole 12. If it is made to become, ie, the relationship of L1 <L2, the said coupling tool 10 will become a more advantageous thing. In this case, the distance L1 is the distance from the edge of the main body 11 closest to the insertion hole 12 on the right side of the drawing to the center of the connecting portion 13, as shown in FIG. 2A and FIG. L2 is the distance from the end edge of the main body 11 closest to the insertion hole 12 on the left side of the drawing to the center of the connecting portion 13, and the distance between the contact edge 12a of each insertion hole 12 and the end edge of the main body 11 is It is the same.

  Each main body 11 is formed of an elastic material, and when the connector 10 is used, both side portions of the connecting portion 13 are bent as shown in FIG. If one part is long or short, the internal stress inherent in the shorter part is stronger than that inherent in the longer part. Therefore, in the example of FIG. 3 for explaining the case of chopsticks, when the connecting tool 10 connecting both the holding members 21 is in a natural state, the end 23 of each holding member 21 connected by the connecting tool 10. A force is applied so that the sides come into contact with each other, and both action portions 22 that are the tips of the respective pinching members 21 are in an open state.

  In other words, in this connection tool 10, when a pair of pinching members 21 are connected by the connection tool 10, the action part 22 is in an open state, and preparations for gripping or pinching an object have already been made. become. For this reason, the pinching tool 20 formed by connecting the pinching members 21 with the connecting tool 10 is configured so that an object sandwiched by the hand enters between the action portions 22 so that the pinching members 21 are placed on the thumbs. If you pinch it with another finger, you can pinch the object naturally.

  Now, the state before the connection tool 10 according to the present invention is developed is as described above. However, the connection tool 10 according to the present invention includes the holder 14 and the main bodies 11 as shown in FIGS. Except for the stopper groove 15 formed in the above, most of the above is followed. 7 and 8 show a holder 14 according to the first embodiment, and FIGS. 9 and 10 show a holder 14 according to the second embodiment and a main body 11 suitable for the holder 14, respectively.

  Moreover, as shown in FIGS. 7-10, the two main bodies 11 which comprise the connector 10 which concerns on this invention are the same shape flat form, and the connection part 13 mentioned above is not provided at all. And can be separated from each other. In other words, as shown in FIGS. 7 and 9, these two main bodies 11 can be opened to each other at portions other than the holder 14.

  The holder 14 shown in FIGS. 7 and 8 has a “box shape” having an insertion hole 14a into which the two main bodies 11 are inserted, and has a very simple shape. Of course, the inside of the insertion hole 14a of the holder 14 is linear so that the linear edge portions of the main bodies 11 can come into contact with each other and can be guided.

  On the other hand, the holder 14 shown in FIGS. 9 and 10 is a little different from the holder 14 shown in FIGS. 7 and 8, particularly as shown in FIGS. The holder 14 also has a straight insertion hole 14a into which the two main bodies 11 are inserted in an overlapping manner, as shown in FIG. 10C, but a part of the insertion hole 14a is As shown in FIG. 10D, a notch 14c is formed.

  A stopper piece 14b is formed in the insertion hole 14a visible through the notch 14c, as shown in FIG. This stopper piece 14b is to be engaged with a stopper groove 15 formed in the long side edge portion of each main body 11, and this stopper groove 15 is shown in FIGS. 10 (a) and 10 (b). As shown in FIG. 5, the holder 14 is formed inside the insertion hole 12 where it can be used.

  These stopper grooves 15 and stopper pieces 14b are engaged with each other as shown in FIGS. 9A and 9B when the main body 11 is opened at the position where the holder 14 is installed. The positional deviation during use of the holder 14, and hence the opening of each clamping member 21, is prevented from changing.
