DETAILED DESCRIPTION [First embodiment] based on Figures 1 to 8 A first embodiment of the present invention will be described. like Figure 1 As shown, the fixing device 1 of this embodiment includes a plug 10 and a socket 20 into which the plug 10 is inserted. An article fastening portion (e.g., a rope body 30 of this embodiment) is installed on the plug 10. The rope body 30 is installed on an arbitrary article such as a camera. A belt that is hung on a part of the user's body (e.g., the neck, etc.) is installed on the socket 20. The user can easily attach and detach the belt to the article by plugging and unplugging the plug 10 from the socket 20. Hereinafter, the width direction (left-right direction) of the fixture 1 is referred to as the Y direction, the thickness direction (up-down direction) of the fixture 1 orthogonal to the Y direction is referred to as the Z direction, and the direction orthogonal to the Z direction and the Y direction is referred to as the X direction (axial direction). In addition, one side of the X direction is referred to as the +X direction, and the other side of the X direction is referred to as the -X direction, and one side of the Z direction is referred to as the +Z direction, and the other side of the Z direction is referred to as the -Z direction. In addition, in the following description, the XYZ directions are used based on the state where the plug 10 is inserted into the socket 20. (Structure of plug 10) The plug 10 has an arbitrary rotational body shape, and the direction along the central axis of the plug 10 corresponds to the X direction (axial direction) of this embodiment. Figure 1 As shown in FIG. 1 , the plug 10 includes a plug body 11 having a cylindrical shape and an annular flange 12 provided on the plug body 11. Hereinafter, one end portion of the plug 10 on the +X side (the front end portion in the insertion direction of the plug 10) is referred to as a plug front end portion 101, and the other end portion of the plug 10 on the -X side (the rear end portion in the insertion direction of the plug 10) is referred to as a plug rear end portion 102. The cord 30 as the article attachment portion of this embodiment is mounted on the plug front end 101. The cord 30 is formed with a loop (not shown), and both ends 31 and 32 of the cord 30 are connected to the plug front end 101. The flange 12 protrudes radially outward from the plug body 11 at the plug rear end 102. The specific structure of the plug 10 and the method of connecting the cord 30 to the plug 10 are not particularly limited. For example, the plug 10 of the present embodiment is composed of a combination of a tube member 13 that forms most of the plug body 11 and the flange 12 and a cover member 14 that blocks the opening of the tube member 13. The two ends 31 and 32 of the cord 30 can also be connected to the plug 10 by inserting and passing through a hole (not shown) at the bottom of the tube member 13 and forming a knot in the internal space of the tube member 13. Alternatively, the two ends 31 and 32 of the cord 30 can also be connected to the plug 10 by being insert-molded when the plug 10 is resin-molded. (Structure of socket 20) Reference Figure 2 to Figure 6 Next, the structure of the socket 20 will be described. The socket 20 includes a socket body 21, a cover 28 mounted on the socket body 21, and a belt mounting portion 29 extending from the socket body 21. In the present embodiment, the socket body 21 and the belt mounting portion 29 are integrally formed of resin. The cover 28 is formed of resin and mounted on the socket body 21. like Figure 2 As shown, the socket body 21 is formed with a storage space S1 for storing the plug 10 and a guide space S2 for guiding the plug 10 to the storage space S1. Specifically, the socket body 21 includes: a pair of side walls 22A and 22B facing each other in the Y direction; a spring portion 23 disposed between the pair of side walls 22A and 22B and extending in the X direction; a pair of support portions 24 and 25 supporting the spring portion 23; a bottom wall portion 26 connecting the +X side ends of the pair of side walls 22A and 22B to each other; and a pair of protrusions 27A and 27B protruding from the pair of side walls 22A and 22B to the inside in the Y direction. In the following description, the socket body 21 is assumed to have a first region AR1 forming the housing space S1 and a second region AR2 forming the guide space S2. The first region AR1 and the second region AR2 are regions arranged in the X direction. The side walls 22A and 22B have a wall shape that is opposite to each other in the Y direction and extends across the first area AR1 and the second area AR2. The side walls 22A and 22B in the first area AR1 are arranged so as to sandwich the storage space S1, and the side walls 22A and 22B in the second area AR2 are arranged so as to sandwich the guide space S2. like Figure 3As shown, the side wall portions 22A and 22B of the first area AR1 have a side wall end portion 221 as an end portion on the +Z side. The side wall end portions 221 of the side wall portions 22A and 22B have a shape that is curved inward in the Y direction, and form a contact surface 222 facing the -Z direction relative to the storage space S1. The contact surface 222 can contact the plug 10 arranged in the storage space S1 in the -Z direction. Such side wall ends 221 of the side wall portions 22A and 22B constitute a stopper portion 220 that is opposite to the spring portion 23 across the storage space S1. In addition, in the first area AR1, the side wall ends 221 of the side wall portions 22A and 22B form an operation opening A1 between each other for exposing the plug 10 from the storage space S1 to the +Z direction. Figure 1 As shown in FIG. 1 , the side walls 22A and 22B of the first area AR1 have a portion on the -X side that is cut in the -Z direction. Thus, the operation opening A1 includes a plurality of opening areas with different sizes in the Y direction. Specifically, Fig. 9 As shown, in the operation opening A1 , a Y-direction dimension D1 of a first opening region A11 exposing the plug rear end portion 102 is wider than a Y-direction dimension D2 of a second opening region A12 exposing the plug front end portion 101 . like Figure 2 As shown in FIG. 1 , the side wall portions 22A and 22B of the second region AR2 have a shape that curves outward in the Y direction as it moves toward the −X direction. Figure 1 As shown, the Z-direction dimension of the side wall portions 22A and 22B of the second region AR2 decreases toward the −X direction. like Figure 3 As shown, the spring portion 23 is disposed between the pair of side wall portions 22A and 22B so as to face the +Z side relative to the storage space S1. Figure 4 As shown, the spring portion 23 has a leaf spring shape extending in the X direction, and has a pair of end portions 231 and 232 arranged in the X direction. Hereinafter, the end portion 231 disposed on the +X side of the pair of end portions 231 and 232 is referred to as a spring front end portion 231, and the end portion 232 disposed on the -X side is referred to as a spring rear end portion 232. In the present embodiment, the spring portion 23 extends from the first region AR1 to the second region AR2 of the socket 20 , the spring front end portion 231 is arranged in the first region AR1 , and the spring rear end portion 232 is arranged in the second region AR2 . In addition, the spring portion 23 has a bent portion 23C bent in the Z direction between the spring front end portion 231 and the spring rear end portion 232. The portion of the spring portion 23 from the spring front end portion 231 to the bent portion 23C (hereinafter, the first extension portion 234) is arranged along the X direction. In addition, the portion of the spring portion 23 from the bent portion 23C to the spring rear end portion 232 (hereinafter, the second extension portion 235) is arranged to be inclined relative to the X direction in a manner that the further it is toward the -X direction, the further it is toward the -Z direction. Therefore, the spring rear end portion 232 is arranged at a position closer to the -Z side than the spring front end portion 231. The spring portion 23 can be elastically deformed in the -Z direction with the above-mentioned bent portion 23C as the center. Specifically, although it will be discussed later, when the plug 10 is arranged in the storage space S1, the spring portion 23 is pressed by the plug 10 and elastically deformed in the -Z direction. Therefore, the spring portion 23 has a pressing portion 233 that applies a pressing force in the +Z direction to the plug 10 arranged in the storage space S1 by its elastic force. The pressing portion 233 is a portion on the +X side relative to the bent portion 23C, and makes the plug 10 arranged in the storage space S1, especially the plug rear end portion 102, press against the stopper 220. like Figure 2 As shown, the support parts 24 and 25 are arranged at positions separated from each other along the X direction, and have a plate shape arranged along the X direction and the Y direction. In addition, the support parts 24 and 25 connect the pair of side wall parts 22A and 22B. Specifically, the support part 24 connects the pair of side wall parts 22A and 22B in the first area AR1, and faces the +Z direction with respect to the storage space S1. On the other hand, the support part 25 connects the pair of side wall parts 22A and 22B in the second area AR2, and faces the +Z direction with respect to the guide space S2. The spring portion 23 is arranged in the gap in the X direction between the support portions 24 and 25. The support portion 24 supports the spring front end portion 231, and the support portion 25 supports the spring rear end portion 232. That is, the support portions 24 and 25 support the spring portion 23 together. In addition, the support parts 24 and 25 have a structure for mounting the cover part 28 discussed later on the socket body part 21. Specifically, Figure 2 As shown, the support portion 24 is formed with a recessed portion 241 opened toward the +Z side, and the first engaging portions 283A and 283B of the cover portion 28 are arranged in the recessed portion 241. The support portion 25 is formed with a pair of recessed portions 251 opened toward the +Z side, and the second engaging portions 284A and 284B of the cover portion 28 are arranged in each recessed portion 251. The bottom wall portion 26 is disposed on the +X side relative to the storage space S1, and connects the +X side ends of the pair of side wall portions 22A and 22B to each other. Figure 4 As shown in FIG. 2 , the bottom wall portion 26 has a contact surface 261 facing the −X direction relative to the storage space S1. Figure 5 As shown, the bottom wall portion 26 has a notch 262 in a shape obtained by partially cutting out the bottom wall portion 26 in the -Z direction so that the rope body 30 can be inserted and penetrated in the X direction. like Figure 2 As shown, the convex portions 27A and 27B are arranged at the ends of the storage space S1 in the -X direction, and have a shape protruding from the side wall portions 22A and 22B in the Y direction. Specifically, the convex portion 27A protrudes inward from the side wall end portion 221 of the side wall portion 22A in the Y direction, and the convex portion 27B protrudes inward from the side wall end portion 221 of the side wall portion 22B in the Y direction. Figure 4 As shown in the figure, the convex portion 27A has a contact surface 271 facing the +X direction with respect to the storage space S1 and an inclined surface 272 facing the -Z direction. In addition, the inclined surface 272 is inclined with respect to the Y direction and the Z direction in such a manner that the more it faces the inner side in the Y direction, the more it is located on the +Z side. In addition, although not shown in the figure, the convex portion 27B also has a contact surface 271 and an inclined surface 272 in the same manner as the convex portion 27A. The protrusions 27A and 27B form an insertion port A2 of the storage space S1. The insertion port A2 is an opening that opens the storage space S1 in the -X direction. The plug 10 is stored in the storage space S1 from the guide space S2 through the insertion port A2. The cover 28 is arranged on the -Z side relative to the spring portion 23 and is attached to the socket body 21. Specifically, the cover 28 includes a plate portion 281 (see Figure 6 ), which covers the -Z side of the spring portion 23; a pair of plug support portions 282A, 282B (reference Figure 3 ), which protrudes from the plate portion 281; a pair of first engaging portions 283A, 283B (reference Figure 2 ), which protrudes from the +X direction end of a pair of plug support portions 282A, 282B; and a pair of second engaging portions 284A, 284B (refer to Figure 2 ) which protrudes from the -X direction ends of a pair of plug support portions 282A, 282B. like Figure 3 As shown, the plug support portion 282A is inserted between the side wall portion 22A and the spring portion 23 in the +Z direction, and the plug support portion 282B is arranged between the side wall portion 22B and the spring portion 23 in the +Z direction. These plug support portions 282A and 282B have a concave arc surface 285 facing the +Z direction. The arc surface 285 can abut against the plug 10 in the Z direction to prevent excessive elastic deformation of the spring portion 23. like Figure 2As shown, the first engaging portions 283A and 283B have claw shapes that protrude from the plug supporting portions 282A and 282B in the +Z direction and are embedded in the recessed portion 241 of the supporting portion 24. The second engaging portions 284A and 284B protrude from the plug supporting portions 282A and 282B in the -X direction and are embedded in the recessed portion 251 of the supporting portion 25. The first engaging portions 283A and 283B are engaged with the supporting portion 24, and the second engaging portions 284A and 284B are engaged with the supporting portion 25, so that the cover portion 28 is mounted on the socket body 21. like Figure 1 As shown, the belt attachment part 29 is arranged along the Y direction, and is formed into a rod shape so as to connect the -X direction ends of the side walls 22A and 22B. There is a gap in the X direction between the belt attachment part 29 and the support part 25, and the belt is wound around the belt attachment part 29. In the socket 20 of the present embodiment described above, the abutting surfaces 271 of the pair of protrusions 27A and 27B and the abutting surface 261 of the bottom wall portion 26 can hold the plug 10 between each other in the X direction. In addition, the pair of side wall portions 22A and 22B can hold the plug 10 between each other in the Y direction. In addition, the side wall end portions 221 (i.e., the stopper portions 220) and the spring portion 23 of the pair of side wall portions 22A and 22B can hold the plug 10 between each other in the Z direction. (Movement of Fixing Device 1) Further references Figure 7 and Figure 8 Next, the operation of the plug 10 and the socket 20 when the fixing device 1 is used will be described. When attaching a belt to an item, the user places the plug 10 in the guide space S2 of the socket 20, and applies pressure in each direction including the +X direction and the -Z direction to the plug 10. As a result, the plug 10 slides from the guide space S2 of the socket 20 toward the storage space S1 (see Figure 7 At this time, the plug 10 contacts the second extension portion 235 of the spring portion 23, and the spring portion 23 is pressed by the plug 10 and deformed in the -Z direction. In addition, the plug 10 is guided by the inclined surfaces 272 of the convex portions 27A and 27B and inserted through the insertion port A2 and inserted into the storage space S1. Next, the user releases the pressure applied to the plug 10. Then, the spring portion 23 returns to its original shape, and the pressing portion 233 of the spring portion 23 applies a pressure F in the +Z direction to the rear end portion 102 of the plug. Figure 8 As shown, the plug 10 is held in the Z direction by the pressing portion 233 of the spring portion 23 and the side wall end portions 221 (ie, the stopper portions 220 ) of the pair of side wall portions 22A and 22B. According to the above steps, if Fig. 9As shown, the insertion of the plug 10 relative to the socket 20 is completed and the strap is installed on the object. When the user carries an item and the belt or cord 30 is twisted to generate a twist, the plug 10 rotates relative to the socket 20 about the central axis along the X direction while sliding relative to the spring portion 23 and the stopper 220. This prevents the twist from being generated. When removing the belt from the article, the user applies pressure in the -X direction and the -Z direction to the plug 10 through the operation opening A1 of the socket 20. At this time, the spring portion 23 is pressed by the plug 10 and deformed in the -Z direction, so the plug 10 moves slightly in the -Z direction and moves in the -X direction at the same time. As a result, the plug 10 is guided by the inclined surfaces 272 of the convex portions 27A and 27B and inserted through the insertion port A2, and moves from the storage space S1 to the guide space S2. After that, the user removes the plug 10 that has moved to the guide space S2 from the socket 20. Through the above steps, the plug 10 is completely unplugged from the socket 20, and the belt is removed from the object. (Effects of this embodiment) As described above, the fixture 1 of the present embodiment includes: the plug 10 having a rotating body shape; and the socket 20 into which the plug 10 is inserted in the axial direction, the socket 20 includes: the belt mounting portion 29 into which the belt is mounted; and the socket main body 21 which forms the storage space S1 in which the plug 10 is arranged, and the socket main body 21 includes: the spring portion 23 having a pair of end portions 231 and 232 arranged in the X direction and facing the +Z direction relative to the storage space S1; a pair of support portions 24 and 25 which support the pair of end portions 231 and 232 of the spring portion 23; and the stopper 220 which faces the -Z direction relative to the storage space S1. The spring portion 23 has a pressing portion 233 between the pair of end portions 231 and 232 for pressing the plug 10 arranged in the storage space S1 against the stopper 220. According to such a structure, the plug 10 can rotate relative to the socket 20 while being sandwiched between the pressing portion 233 of the spring portion 23 and the stopper 220. In addition, the pressing portion 233 of the spring portion 23 is located between the pair of end portions 231 and 232 supported by the support portions 24 and 25, so that the strength of the spring portion 23 for pressing the plug 10 can be easily ensured. In addition, there is a case where the rope body 30 is deformed due to a force applied from a belt or the like. Figure 7 The plug 10 moves as shown by the arrow R1, so that a force is applied to the plug 10 as shown by the arrow R2 from the cord body 30. In this case, a force such as to tilt the plug 10 and remove it from the socket 20 acts on the plug 10, but the plug 10 can be pressed against the stopper 220 by the pressing portion 233 of the spring portion 23 to prevent the plug 10 from falling off. Therefore, according to the fixing device 1 of the present embodiment, it is possible to suppress the twist between the article and the belt while ensuring sufficient attachment strength. Furthermore, when magnets or metal springs are used as in the past, environmental awareness and cost issues such as the need for classification when discarded become problems. On the other hand, the fixture 1 of this embodiment can be formed of resin, so environmental awareness and cost issues can also be resolved. In the present embodiment, the spring portion 23 and the pair of support portions 24 and 25 are integrally formed. According to such a structure, it is easier to ensure the strength of the spring portion 23 for pressing the plug 10. In addition, when manufacturing the fixture 1, there is no need to add a step of the spring portion 23, so the manufacturing cost of the fixture 1 can be reduced. In this embodiment, the socket 20 further includes a pair of side walls 22A and 22B arranged in the Y direction across the storage space S1 . The pair of side walls 22A and 22B have side wall ends 221 bent inward in the Y direction to form a stopper 220 . With such a structure, the stopper 220 can appropriately come into contact with the plug 10 . In this embodiment, the socket body 21 further includes a pair of protrusions 27A and 27B protruding from the pair of side walls 22A and 22B inward in the Y direction on the -X side relative to the storage space S1, and the plug rear end portion 102 can abut against the pair of protrusions 27A and 27B in the X direction. According to such a configuration, it is possible to appropriately suppress the plug 10 from falling out of the housing space S1 of the socket 20 in the −X direction. In the present embodiment, the pressing portion 233 of the spring portion 23 presses the plug rear end portion 102 . For example, as described above, there is a case where the rope body 30 Figure 7 The plug 10 moves as shown by the arrow R1, and the cord body 30 applies a force as shown by the arrow R2 to the plug 10. In this case, a force such that the rear end portion 102 of the plug moves downward in the -Z direction acts on the plug 10, and the pressing portion 233 of the spring portion 23 supports the rear end portion 102 of the plug, thereby suppressing the inclination of the plug 10. As a result, the plug 10 is maintained in a state where it can abut against the convex portions 27A and 27B, and the plug 10 can be more appropriately suppressed from falling off in the -X direction. In the present embodiment, the side wall ends 221 of the pair of side wall portions 22A and 22B form an operation opening A1 for exposing the plug 10 from the storage space S1 to the +Z direction. The Y-direction dimension D1 of a first opening area A11 for exposing the plug rear end 102 in the operation opening A1 is wider than the Y-direction dimension D2 of a second opening area A12 for exposing the plug front end 101. In such a structure, when the user removes the plug 10 from the socket 20 , the user can easily operate the plug 10 through the operation opening A1 . In the present embodiment, the plug 10 includes a cylindrical plug body 11 and a flange 12 protruding from the plug body 11 . In such a structure, when the user operates the plug 10 in the storage space S1, the flange portion 12 functions as a non-slip portion for the user's fingers, etc. This can improve the operability of the plug 10. In this embodiment, the socket 20 also includes a cover portion 28 installed on the socket body portion 21, and the cover portion 28 also includes: a plate portion 281; and a pair of plug support portions 282A, 282B, which protrude from the plate portion 281 in the +Z direction in a manner of inserting and penetrating the gap between the pair of side wall portions 22A, 22B and the spring portion 23. In such a structure, when the plug 10 is pressed in the −Z direction, the plug support portions 282A and 282B can abut against the plug 10 in the Z direction, thereby preventing excessive elastic deformation of the spring portion 23 . [Second embodiment] The fixture 1 of the second embodiment includes the plug 10 similar to that of the first embodiment and a socket 20A having a structure different from that of the first embodiment. Fig.10 The socket 20A of the second embodiment will be described. Note that the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof will be omitted or simplified. The socket 20A of the second embodiment includes a socket body 21A that forms a storage space S1 and the like, and a belt attachment portion 29 that extends from the socket body 21A. The socket body 21A includes a body base 210 and a cover 28A attached to the body base 210 . The main body base 210 includes the portion of the socket main body 21 described in the first embodiment except for the spring portion 23. Specifically, the main body base 210 includes: a pair of side wall portions 22A and 22B facing each other in the Y direction; a bottom wall portion 26 that connects the +X side ends of the pair of side wall portions 22A and 22B to each other; and a pair of protrusions 27A and 27B that protrude from the pair of side wall portions 22A and 22B to the inside in the Y direction. In addition, the main body base 210 includes a wall portion 25A that connects the pair of side wall portions 22A and 22B in the second area AR2 and faces the +Z direction relative to the guide space S2. The cover portion 28A includes a plate portion 281, a spring portion 23A provided on the plate portion 281, and an engaging portion (not shown). The cover portion 28A is integrally molded from resin. The spring portion 23A has a pair of end portions 231 and 232 similarly to the spring portion 23 of the first embodiment and faces the +Z direction relative to the storage space S1. The two end portions 231 and 232 of the spring portion 23A are supported by the plate portion 281. That is, the two end portions 281A and 281B in the X direction of the plate portion 281 function as a pair of supporting portions of the present invention. In addition, the spring portion 23A has a pressing portion 233 for pressing the plug 10 stored in the socket 20A. Such a fixing device of the second embodiment can produce the same effects as those of the first embodiment. [Modifications] The specific structure of the fixing tool 1 of each embodiment is not limited to the above description. Hereinafter, a modification of the first embodiment will be described, and the second embodiment may also be modified in the same manner. In the first embodiment described above, the plug 10 is not limited to a cylindrical shape, and may have any rotating body shape so as to be rotatable relative to the socket 20 . In the first embodiment, the socket 20 is not limited to include the cover 28, and the cover 28 may be omitted. In addition, the pair of plug support portions 282A and 282B in the cover 28 may be omitted. In the first embodiment, the operation opening A1 of the socket 20 has different Y-direction dimensions D1 and D2, but the present invention is not limited thereto. For example, the Y-direction dimension of the operation opening A1 may be constant along the X-direction. In addition, in the above-mentioned embodiments, the operation opening A1 of the socket 20 may be omitted, and the socket 20 may have a substantially cylindrical shape. In the first embodiment, the pressing portion 233 of the spring portion 23 applies pressure to the plug rear end portion 102, but the present invention is not limited thereto. That is, the pressing portion 233 of the spring portion 23 may also apply pressure to any portion of the plug 10 (e.g., a portion closer to the -X side than the center portion of the plug 10 in the X direction). In the first embodiment, the socket 20 is not limited to having a pair of protrusions 27A and 27B forming the insertion port A2, and the pair of protrusions 27A and 27B may be omitted. For example, it is assumed that as long as the article is hung on the belt, the -X direction is equivalent to the upper side in the vertical direction, so even if the movement of the plug 10 from the storage space S1 to the -X direction is not restricted, the plug 10 can be held in the socket 20 without any problem. In the first embodiment, the side wall end 221 of the pair of side wall portions 22A and 22B may be in other shapes as long as it is a shape constituting the stopper 220. In addition, in each of the above embodiments, the stopper 220 may be not a part of the pair of side wall portions 22A and 22B, but a part of the tubular socket 20 forming the storage space S1. In the first embodiment, the socket body 21 is integrally formed, but the present invention is not limited thereto. For example, the spring portion 23 may be formed as a member separate from the socket body 21 and attached to the pair of support portions 24 and 25 . In the first embodiment described above, the article fastening portion is the string body 30 , but the present invention is not limited thereto, and an article fastening portion having any structure may be attached to the plug 10 .
