Description

[Technical field]

[0001] The present invention relates to a fishhook remover. [Background technology]

[0002] Conventionally, there is known a fishhook remover that has a linear moving body having a fishhook locking part made of wire bent into a hook shape, and that moves in the forward and backward directions relative to a guide tube (see, for example, Patent Document 1). On the other hand, for ease of processing and manufacturing, and ease of positioning the lever and the groove provided in the guide tube to be in the correct phase during assembly, there are cases where a hook-shaped fishhook locking part is processed into the tip of a metal plate material such as stainless steel. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6928378 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a metal plate-shaped movable body having a fishhook locking portion is used, there is a problem that when removing the hook, if a large torsional force is generated by twisting the fishhook remover with the fishhook locked by the fishhook locking portion, the plate-shaped movable body will be deformed, making it difficult to move it relative to the guide tube, and there is room for improvement in this regard.

[0005] The present invention has been made in consideration of these circumstances, and its object is to provide a fishhook remover that can prevent deformation of the moving body while maintaining ease of processing and manufacturing, thereby maintaining good usability. [Means for solving the problem]

[0006] (1) A first aspect of the fishhook remover of the present invention is a fishhook remover for removing a fishhook from a hooked fish, comprising: a guide tube having an opening and a fishhook retaining groove at one longitudinal end; and a plate-shaped moving body protruding from the opening to one end of the guide tube and attached so as to be movable in the longitudinal direction, the plate-shaped moving body having a fishhook locking portion at its protruding tip for locking the fishhook in the fishhook retaining groove by moving to the other end of the guide tube, the fishhook locking portion penetrating the thickness direction of the plate-shaped moving body and capable of locking the fishhook, the plate-shaped moving body having an escape passage portion connected to the fishhook locking portion, the dimension of the escape passage portion gradually decreasing from the side of the plate-shaped moving body in the longitudinal direction as it moves from the one end side to the other end side of the guide tube, and the escape passage portion having an escape surface communicating with the side of the plate-shaped moving body.

[0007] According to the first aspect of the fishhook remover of the present invention, when a fishhook is removed from a fish, with the fishhook engaged with the fishhook engaging part of the plate-shaped moving body, the fishhook exerts a tensile force (a force toward one end of the plate-shaped moving body) on the plate-shaped moving body, and also exerts a torsional load in the direction of rotation about the cylindrical axis. This load generates a force between the contact surface of the fishhook and the fishhook engaging part that moves the fishhook toward the release surface formed in the release passage part, but the fishhook does not move due to the frictional force with the release surface. On the other hand, when the torsional load increases further and the force that moves the fishhook along the release surface exceeds the frictional force with the release surface, the fishhook moves along the release surface and comes out of the fishhook engaging part to the side of the plate-shaped moving body.

[0008] In this way, in the present invention, when a torsional load acts on the plate-shaped moving body, the fishhook locked by the fishhook locking part can be released from the plate-shaped moving body. Therefore, even if the torsional load on the fishhook locking part increases with the fishhook locked in the state where it is locked in the fishhook locking part, plastic deformation of the plate-shaped moving body can be prevented, and the problem of the plate-shaped moving body being unable to move relative to the guide tube can be suppressed.

[0009] (2) In a second aspect of the present invention, in the fishhook remover of the first aspect, it is preferable that the relief surface is connected to the fishhook locking portion.

[0010] In this case, when a torsional load acts on the plate-shaped movable body, the fishhook is positioned at the fishhook locking portion, and an escape surface is provided to connect to this fishhook locking portion, so that the fishhook can be smoothly moved along the escape surface to the outside of the fishhook locking portion and released depending on the magnitude of the frictional force.

[0011] (3) In a third aspect of the present invention, in the fishhook remover of the first or second aspect, it is preferable that the plate-shaped movable body is a stainless steel metal plate, and the inclination angle of the relief surface is in the range of 30 to 50 degrees with respect to the longitudinal axis.

[0012] In this case, in the present invention, the frictional force between the release surface of the fishhook and the fishhook is secured under a small torsional load, so that the fishhook does not move and is difficult to come off from the hooking part, and when a large torsional load is applied to the fishhook remover, the fishhook exceeds the frictional force between the release surface and moves along the release surface, disengages from the hooking part, and is released from the fishhook remover. If the inclination angle of the release surface is less than 30 degrees, the frictional force between the release surface and the fishhook becomes large even when a certain large torsional load is applied, so that the fishhook does not move along the release surface and the plate-like moving body may be plastically deformed. On the other hand, if the inclination angle of the release surface is more than 50 degrees, the frictional force between the release surface of the fishhook and the fishhook cannot be secured sufficiently, so that the fishhook comes off even under a small torsional load.

[0013] (4) A fourth aspect of the present invention may be characterized in that, in the fishhook remover of any one of the first to third aspects, one end of the guide tube is provided with a conical portion tapering toward the opening, and inclined surfaces inclined toward the plate-like moving body by cutting out the conical portion on both sides of the plate surface of the plate-like moving body, and the fishhook retaining groove is disposed on one end side of the inclined surfaces.

[0014] In this case, in the present invention, the front end of the guide tube is conical in shape and further has an inclined surface formed thereon, making it easy to insert into the fish's mouth and enabling the fishhook engaging portion of the plate-shaped moving body to accurately reach the fishhook that has been hooked into the fish. In addition, by forming inclined surfaces on both sides of the guide tube that sandwich the plate-shaped moving body, the opening shape at the front end of the guide tube can be formed into a rectangular shape that is the same as the cross-sectional shape of the plate-shaped moving body, so that the plate-shaped moving body can be moved in the forward and backward directions by being guided by the guide tube in a stable posture without rotating. Effect of the Invention

[0015] According to the fishhook remover of the present invention, it is possible to prevent deformation of the moving body and maintain good operability while maintaining ease of processing and manufacturing. [Brief description of the drawings]

[0017] Hereinafter, an embodiment of a fishhook remover according to the present invention will be described with reference to the drawings. Note that in each drawing, the scale of each component may be appropriately changed as necessary in order to make each component large enough to be visible.

[0018] As shown in Figs. 1 and 2, a fishhook remover 1 of this embodiment is a tool used when removing a fishhook 100 (see Fig. 6) from a hooked fish during fishing.

[0019] The fishhook remover 1 comprises a guide tube 2 having an opening 2a and a fishhook holding groove 21 at one end in the longitudinal direction (front-to-rear direction X), a plate-shaped moving body 3 which protrudes from the opening 2a to one end side (front side X1) of the guide tube 2 and is attached so as to be movable in the front-to-rear direction X, and has a fishhook locking portion 31 at its protruding tip end which holds the fishhook 100 together with the fishhook holding groove 21 by moving to the other end side (rear side X2) of the guide tube 2, a handle portion 4 provided at the other end (rear end) of the guide tube 2, and a lever portion 5 which protrudes in the outer diameter direction of the guide tube 2 in conjunction with the plate-shaped moving body 3.

[0020] Here, the longitudinal direction of the guide tube 2 is defined as the front-to-rear direction X, the side of the guide tube 2 where the hook holding groove 21 is provided is designated as the front or front side (one end side) by the symbol X1, and the other end where the handle portion 4 is provided is designated as the rear or rear side (the other end side) by the symbol X2. The guide cylinder 2 is formed into a cylindrical shape with a circular cross section, and the central axes of the guide cylinder 2 and the plate-like movable body 3 are disposed on a common axis. Hereinafter, this common axis will be referred to as the cylinder axis O, and the front-rear direction X will be along the direction of the cylinder axis O. In a plan view of the fishhook remover 1 seen from the direction of the cylinder axis O, the direction perpendicular to the cylinder axis O will be referred to as the radial direction, and the direction going around the cylinder axis O will be referred to as the circumferential direction.

[0021] As shown in FIG. 2, the guide tube 2 is a rod-like hollow tube that is long in the front-rear direction X. The front end portion of the guide tube 2 is provided so as to be separable in the front-rear direction X. The guide tube 2 includes a cylindrical front end member 22 having a pair of fishhook holding grooves 21 formed at the front end portion at positions that face each other in the radial direction in a side view, and a cylindrical main body member 23 that extends along the cylindrical axis O from the rear of the front end member 22 to the handle portion 4. A male thread 23a is formed at the front end of the main body member 23. A female thread 22a is formed at the rear end of the front end member 22. The front end member 22 is fixed to the main body member 23 by tightening the female thread 22a into the male thread 23a.

[0022] A handle portion 4 is fixed to the rear end of the guide tube 2 by a fixing screw 41. The handle portion 4 is a grip that protrudes from the outer circumferential surface of the guide tube 2 toward the outside in the radial direction perpendicular to the tube axis O, and is the part that is gripped when removing the fishhook 100. The movement of the handle portion 4 in the front-rear direction X and the rotation in the circumferential direction are restricted with respect to the guide tube 2. A rear end 322a of a spring member 322, which will be described later, is connected to the fixing screw 41. In addition, a cover member 42 is attached to each of both radial ends of the handle portion 4.

[0023] As shown in Figures 3 to 5, the front end of the front end member 22 has a cone-shaped portion 22b tapering toward the opening 2a, and inclined surfaces 22c that are formed by cutting out the cone-shaped portion 22b on both sides of the plate surface of the plate-shaped moving body 3 and inclining toward the plate-shaped moving body 3. A fishhook holding groove 21 is disposed on the front end side of the inclined surface 22c. A passage portion 24 is formed inside the front end of the front end member 22, extending in the front-rear direction X and communicating with the opening 2a. The opening cross section of the passage portion 24 matches the cross-sectional shape of the plate-shaped moving body 3, and supports the plate-shaped moving body 3 so that it can slide in the front-rear direction X.

[0024] A pair of opposing fishhook holding grooves 21 formed at the front end of the front end member 22 are cut out rearward from the opening 2a, and are V-shaped at the bottom of the groove, the width of which narrows from the front to the rear. The fishhook holding grooves 21 hold the fishhooks 100 engaged by the fishhook engaging portions 31 of the plate-like moving body 3.

[0025] As shown in Fig. 4 and Fig. 6(a), the fishhook holding groove 21 is for holding the curved portion 100a or the body portion 100b of the fishhook 100. As shown in Fig. 6(b), in use, when a portion of the fishhook 100 is placed on and locked to the fishhook locking portion 31 of the plate-like moving body 3, the plate-like moving body 3 is moved backward with respect to the front end member 22, whereby the portion of the fishhook 100 that is placed on the hook is sandwiched and held between the hook holding groove 21. Then, when the plate-like moving body 3 is moved backward relative to the guide tube 2 (hereinafter, sometimes simply referred to as "backward"), the fishhook 100 that is sandwiched between the hook locking portions 31 of the plate-like moving body 3 and the bottom of the hook holding groove 21 is sandwiched in the front-rear direction X by the hook locking portions 31 of the plate-like moving body 3, which will be described later, and the bottom of the hook holding groove 21.

[0026] A pair of long holes 23b that are long in the front-rear direction X are provided near the rear end of the main body member 23 for attaching the lever portion 5 to the plate-shaped moving body 3. The range in which the plate-shaped moving body 3 can move relative to the guide tube 2 in the front-rear direction X is limited by the length of the long holes 23b in the front-rear direction X.

[0027] As shown in FIG. 2, the plate-shaped moving body 3 is fixed to the front end 32a of the shaft portion 32 that is inserted into the guide tube 2 and is long in the front-rear direction X. That is, the plate-shaped moving body 3 is provided in a state in which it extends forward from the front end 32a of the shaft portion 32. The shaft portion 32 has a square cross section. The rear end 32b of the shaft portion 32 is connected to the lever portion 5 that is attached to the outer periphery of the guide tube 2 by a connecting shaft member 51. The shaft portion 32 is provided with a through hole 32c through which the connecting shaft member 51 can be inserted, penetrating in a direction perpendicular to the longitudinal direction of the shaft portion 32. The plate-shaped moving body 3 is integrated with the lever portion 5 by inserting the connecting shaft member 51 into the pair of long holes 23b of the guide tube 2 and into the through hole 32c of the shaft portion 32.

[0028] The lever portion 5 includes the connecting shaft member 51 inserted into the long hole 23b of the guide tube 2, and a lever body 52 protruding outward in the radial direction of the guide tube 2 and in the same direction as the longitudinal direction of the handle portion 4. The lever portion 5 is connected to the shaft portion 32 of the plate-shaped moving body 3 by the connecting shaft member 51, and by gripping the lever body 52 and moving it back and forth, the lever portion 5 and the plate-shaped moving body 3 can be moved relative to the guide tube 2 in the front-rear direction X.

[0029] The plate-shaped moving body 3 is biased toward the front side X1 by a spring member 322 provided on the rear end portion 32b of the shaft portion 32. That is, the plate-shaped moving body 3 and the lever portion 5, which are integrated together, can move in the front-rear direction X within a predetermined range relative to the guide tube 2, but unless a force is applied to move them toward the rear side X2, the elastic force of the spring member 322 causes the connecting shaft member 51 to be located at the front end of the long hole 23b, and the plate-shaped moving body 3 and the lever portion 5 are also located at the front end within the movable range.

[0030] The plate-shaped moving body 3 and the lever portion 5 are moved backward X2 by applying a force resisting the elastic force of the spring member 322, and when this force is released, the plate-shaped moving body 3 and the lever portion 5 are moved back to their front end positions by the elastic force of the spring member 322.

[0031] 3, 5 and 6, the plate-shaped moving body 3 is a stainless steel metal plate and is a long member. The front end of the plate-shaped moving body 3 has a hook portion 33 bent into a hook shape. The hook portion 33 has an opening 3a formed by the cut-out portion of one side. The hook portion 33 includes a fishhook locking portion 31 formed by a bent portion that is the front end side X1, and an escape passage portion 34 connected to the fishhook locking portion 31 and extending from the fishhook locking portion 31 toward the opening 3a.

[0032] The opening 3a is a space for allowing the fishhook 100 to be caught by the fishhook catcher 31 through the escape passage 34 (see FIG. 7). The fishhook catcher 31 is capable of receiving the fishhook 100 and penetrates the plate-like moving body 3 in the thickness direction.

[0033] The fishhook locking portion 31 is a portion where the plate-shaped moving body 3 is placed against the fishhook 100 and engages with it from the front X1. When the plate-shaped moving body 3 is moved rearward relative to the guide tube 2 (hereinafter, sometimes simply referred to as "retracting"), the fishhook 100 is clamped between the fishhook locking portion 31 and the fishhook retaining groove 21 of the front end member 22 of the guide tube 2, so that the backward movement of the plate-shaped moving body 3 is restricted. When the fishhook 100 is not engaged with the fishhook engaging portion 31, the fishhook engaging portion 31 is not held in the fishhook holding groove 21, and the plate-like moving body 3 can move backward within the guide tube 2.

[0034] The relief passage portion 34 has a dimension gradually decreasing from the side surface 3b of the plate-shaped moving body 3 from the front side X1 to the rear side X2, and has a relief surface 34a communicating with the side surface 3b of the plate-shaped moving body 3. The relief surface 34a is connected to the fishhook locking portion 31. The inclination angle θ of the relief surface 34a is in the range of 30 to 50 degrees with respect to the cylinder axis O in the front-rear direction X.

[0035] As shown in Fig. 7, when a torsional load rotating in the circumferential direction acts on the plate-like moving body 3 with the fishhook 100 engaged with the fishhook engaging portion 31, the fishhook 100 tries to move toward the opening 3a along the inclined surface of the release surface 34a (in the direction of the arrow E in Fig. 7). That is, a force F2 (see Fig. 3) is generated in a direction in which the fishhook 100 moves toward the opening 3a along the release surface 34a. Note that this force F2 is generated by the fishhook 100 receiving a torsional load while abutting against the abutment surface 33a (the surface of the inner surface of the hook portion 33 extending from the fishhook engaging portion 31 to the rear side X2 in the front-rear direction X) on the opposite side to the inclined release surface 34a across the fishhook engaging portion 31, as shown in Fig. 3.

[0036] 3, when the above-mentioned F2×cosθ exceeds the tensile force F1 that pulls the fishhook 100 toward the front side X1 due to the weight of the fish or the pulling force of a person (F2×cosθ>F1), the fishhook 100 moves along the escape surface 34a. That is, until the torsion of the plate-like moving body 3 reaches F2×cosθ=F1, the movement of the fishhook 100 is restricted by the friction with the escape surface 34a and the fishhook 100 is held by the fishhook locking part 31. When F2×cosθ>F1, the force of the fishhook 100 moving along the escape surface 34a becomes larger than the frictional force, and the fishhook 100 moves along the escape surface 34a and is released from the opening 3a.

[0037] Next, a method of using the fishhook remover 1 thus configured will be described in detail with reference to the drawings. 2 and 3, the fishhook locking part 31 of the plate-like moving body 3 is applied to and locked on the curved part 100a or the body part 100b of the fishhook 100 that has been hooked on a fish. At this time, the fishhook 100 itself may be locked in the hook part 33 through the opening 3a of the plate-like moving body 3, or the fishhook locking part 31 may be applied to the line first, and then the hook part 33 may be moved toward the fishhook 100 while being guided by the line. This makes it possible to easily apply the fishhook locking part 31 to the fishhook 100 even when, for example, the fishhook 100 has been swallowed and hooked deep in the mouth of the fish, making it difficult to confirm the position of the fishhook 100.

[0038] 2 and 6(a) and (b), when the fishhook 100 is engaged with the fishhook engaging part 31, by gripping the handle part 4 and the lever part 5 and moving the lever part 5 backward relative to the handle part 4, the hook part 33 of the plate-like moving body 3 moves backward X2 in conjunction with the fishhook 100, and the engaged fishhook 100 is clamped between the fishhook engaging part 31 of the plate-like moving body 3 and the fishhook holding groove 21 of the front end member 22 of the guide tube 2. Then, by an operator rotating and twisting the fishhook remover 1 in the circumferential direction, the fishhook 100 can be forcibly rotated and pulled out from the fish or the like.

[0039] Before the fishhook 100 is held, i.e., when the torsional load acting on the fishhook remover 1 is below a predetermined value after the fishhook 100 has only been engaged with the fishhook engaging portion 31 and before the fishhook 100 is clamped by the fishhook holding groove 21, the fishhook 100 is maintained engaged with the fishhook engaging portion 31 by friction with the release surface 34a. On the other hand, when the torsional load acting on the fishhook remover 1 exceeds a predetermined angle, the fishhook 100 slides on the release surface 34a and passes through the release passage portion 34 to be released from the opening 3a. Therefore, when a large torsional load acts on the plate-like moving body 3, the fishhook 100 is released, and since a large load is not applied to the plate-like moving body 3, plastic deformation of the plate-like moving body 3 can be suppressed.

[0040] After the fishhook 100 has been pulled out from the fish or the like, the lever portion 5 is released, and the plate-shaped moving body 3 moves back to its front end due to the force of the spring member 322, and the fishhook 100 is released from the hook holding groove 21.

[0041] Next, the operation of the fishhook remover 1 thus configured will be described in detail with reference to Figs. The fishhook remover 1 according to this embodiment includes a guide tube 2 having an opening and a fishhook holding groove 21 at its front end, and a plate-like moving body 3 having a fishhook locking portion 31 at its protruding tip end, which protrudes from the opening to a front end side X1 of the guide tube 2, is attached to be movable in the front-rear direction X, and locks a fishhook 100 in the fishhook holding groove 21 by moving to a rear end side X2 of the guide tube 2. The fishhook locking portion 31 is capable of locking the fishhook 100 and penetrates the plate-like moving body 3 in the thickness direction. The plate-like moving body 3 has an escape passage portion 34 connected to the fishhook locking portion 31. The escape passage portion 34 has a dimension from the side surface of the plate-like moving body 3 gradually decreasing from the front to the rear, and has an escape surface 34a communicating with the side surface of the plate-like moving body 3.

[0042] As a result, in this embodiment, when the fishhook 100 is removed from the fish, in a state where the fishhook 100 is engaged with the fishhook engaging portion 31 of the plate-like moving body 3, the fishhook 100 exerts a tensile force (a force in a direction to move the plate-like moving body 3 forward) on the plate-like moving body 3, and also exerts a large torsional load in the direction of rotation about the cylinder axis O. This load exerts a force between the contact surface of the fishhook 100 and the fishhook engaging portion 31 to move the fishhook 100 to the escape surface 34a formed in the escape passage portion 34, but the fishhook 100 does not move due to the frictional force with the escape surface 34a. On the other hand, when the torsional load further increases and the force to move the fishhook 100 along the escape surface 34a exceeds the frictional force with the escape surface 34a, the fishhook 100 moves along the escape surface 34a and comes out of the fishhook engaging portion 31 to the side surface of the plate-like moving body 3.

[0043] To explain in more detail, the fishhook 100 is ultimately held in the fishhook holding groove 21 provided in the guide tube 2 while remaining engaged with the fishhook engaging portion 31, and is fixed in both the front-rear direction X and the circumferential direction. In this state, the fishhook remover 1 is twisted relative to the fish so that the tip of the fishhook 100 is released from the fish, and the fishhook 100 is removed. At this time, the plate-like moving body 3 is housed in the passage 24 in the guide tube 2, and the fishhook 100 is also engaged with the fishhook holding groove 21, so that the plate-like moving body 3 will not deform even if a torsional load is applied.

[0044] In this manner, in this embodiment, when a torsional load acts on the plate-shaped moving body 3 , the fishhook 100 locked by the fishhook locking portion 31 can be released from the plate-shaped moving body 3 . Therefore, even if the torsional load on the hook remover 1 increases when the fishhook 100 is engaged with the fishhook engaging portion 31, plastic deformation of the plate-shaped moving body 3 can be prevented, and the problem of the plate-shaped moving body 3 being unable to move relative to the guide tube 2 can be suppressed.

[0045] In this embodiment, the relief surface 34 a is connected to the fishhook locking portion 31 . In this case, the fishhook 100 is positioned at the fishhook engaging portion 31 when a twist is applied to the plate-shaped moving body 3, and the escape surface 34a is provided to connect to this fishhook engaging portion 31, so that the fishhook 100 can be smoothly moved along the escape surface 34a to the outside of the fishhook engaging portion 31 and released depending on the magnitude of the frictional force.

[0046] In this embodiment, the plate-shaped movable body 3 is a metal plate made of stainless steel, and the inclination angle θ of the relief surface 34a is in the range of 30 to 50 degrees with respect to the axis in the longitudinal direction.

[0047] Therefore, in this embodiment, the frictional force between the release surface 34a of the fishhook 100 and the fishhook does not move and is difficult to come off from the fishhook locking part 31 under a small torsional load, and when a large torsional load is applied to the fishhook remover 1, the fishhook 100 exceeds the frictional force between the release surface 34a and moves along the release surface 34a, and is released from the fishhook locking part 31 and is released from the fishhook remover 1. If the inclination angle of the release surface 34a is less than 30 degrees, the frictional force between the release surface 34a and the fishhook does not move along the release surface 34a even when a predetermined large torsional load is applied, so that the plate-like moving body 3 may be plastically deformed. Also, if the inclination angle θ of the release surface 34a exceeds 50 degrees, the frictional force between the release surface 34a of the fishhook 100 and the fishhook 100 may come off even under a small torsional load. This angle may be close to 30° if the friction coefficient between the fishhook 100 and the fishhook locking portion 31 is reduced by surface treatment, etc., and may be close to 50° if the surface roughness and friction coefficient are increased by treatment such as sandblasting. If no surface treatment is applied, the angle is preferably 35° to 45°.

[0048] In addition, in this embodiment, one end of the guide tube 2 is provided with a conical portion 22b that tapers toward the opening 2a, and inclined surfaces 22c that are cut out of the conical portion 22b on both sides of the plate surface of the plate-shaped moving body 3 and incline toward the plate-shaped moving body 3, and a fishhook holding groove 21 is arranged on one end side of the inclined surface 22c.

[0049] Therefore, in this embodiment, the front end of the guide tube 2 is conical in shape and further has an inclined surface 22c, making it easy to insert into the fish's mouth and allowing the fishhook engaging portion 31 of the plate-shaped moving body 3 to accurately reach the fishhook 100 that has been hooked on the fish. In addition, in this embodiment, inclined surfaces 22c are formed on both sides of the guide tube 2 sandwiching the plate-shaped moving body 3, so that the opening shape of the front end of the guide tube 2 can be formed into a rectangular shape that is the same as the cross-sectional shape of the plate-shaped moving body 3. Therefore, the plate-shaped moving body 3 can be moved in the forward / backward direction X by being guided by the guide tube 2 in a stable posture without being rotated.

[0050] The fishhook remover 1 according to this embodiment configured as described above can maintain ease of processing and manufacturing while preventing deformation of the movable body and maintaining good operability.

[0051] Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, those that are within the scope of the equivalents, and the like.

[0052] For example, in the above embodiment, the relief surface 34a is not limited to being connected to the fishhook locking portion 31.

[0053] In this embodiment, the plate-shaped moving body 3 is a stainless steel metal plate, but may be made of other metals. In this embodiment, when the plate-shaped moving body 3 is made of stainless steel, the inclination angle θ of the relief surface 34a is set to a range of 35 to 45 degrees with respect to the longitudinal axis, but when the plate-shaped moving body 3 is made of other metals, the inclination angle θ of the relief surface 34a may be set according to the characteristics (friction coefficient, etc.) of the metal.

[0054] In this embodiment, the guide tube 2 is provided at one end with a conical portion 22b tapering toward the opening 2a, and on both sides of the plate surface of the plate-like moving body 3, the conical portion 22b is cut out to have an inclined surface 22c that is inclined toward the plate-like moving body 3, and the fishhook holding groove 21 is disposed on one end side of the inclined surface 22c, but the guide tube 2 may have a shape in which the conical portion 22b and the inclined surface 22c are not formed. In this embodiment, the guide tube 2 is divided into two parts, the front end member 22 and the main body member 23, but it may be an integrated guide tube without being divided.
