Description

The present invention is capable of holding two or three types of long bodies having different sizes by a long body holder provided with a pair of holding pieces, and after once holding a large body having a large size. Is a long body holding structure that makes it possible to visually recognize that, and prevents a small long body from being held in an incomplete state by the same long body holder, and a long body It relates to a holding tool.
In the present specification, the term “long body” is a concept including long pipes such as water supply pipes, hot water supply pipes and electric pipes, and long cables such as electric wires and cables. Is not limited to a circle.

  The structures disclosed in Patent Documents 1 and 2 are known as structures capable of holding two types of large and small diameter pipes with the same pipe holder provided with a pair of holding pieces. In Patent Document 1, an adapter (small diameter) is used for holding a large-diameter tube by a pair of holding pieces of a tube holder and changing the size of the tube that can be held to a small diameter in an insertion opening of the pair of holding pieces. By fitting the tube holder) and holding the small-diameter tube in the adapter, two types of tubes having different outer diameters can be held by the same tube holder.

  However, in the tube holder of Patent Document 1, it is not possible to hold two types of tubes having different outer diameters only with the same tube holder, but the outer diameter size of the tube that can be held by the tube holder is reduced to a small diameter. The use of an adapter to be changed is indispensable and requires a separate member.

  The tube holder disclosed in Patent Document 2 is composed of an outer pair of large-diameter holding pieces for holding a large-diameter pipe and a pair of small-diameter holding pieces provided on the inner side. In a state where the pair of small diameter holding pieces are forcibly expanded to the extent that the large diameter tube can be held, the pair of small diameter holding pieces are held by the pair of outer large diameter holding pieces. It is a structure to hold.

  In the case of a tube holder that holds both large and small diameter tubes, it is often the case that after the other tube is mistakenly held during work, this error is noticed and the original tube is held. For example, there is a case where it is necessary to hold a small-diameter tube originally, but once the large-diameter tube is mistakenly held, this large-diameter tube is removed to hold the original small-diameter tube. In appearance, it appears that the small-diameter pipe is held without any problem.

  However, it is well known that the pair of small-diameter holding pieces that are forcibly expanded beyond the limit of elastic deformation by the large-diameter pipe are partially plastically deformed and do not recover to the original shape. Therefore, even if it seems that the small-diameter pipe is held by the pair of small-diameter holding pieces, actually, the small-diameter pipe is not firmly held by the elastic restoring force of the pair of small-diameter holding pieces, The small diameter tube is simply disposed between the pair of small diameter holding pieces. As a result, the small-diameter pipe swings up and down, left and right between the pair of holding pieces when passing water, or, in a more severe case, from between the pair of holding pieces due to vibration or water hammer phenomenon. Since the small-diameter pipe may even come off, the small-diameter pipe is not completely held.

  In the present invention, when two or three types of long bodies having different sizes are held by the same long body holder provided with a pair of holding pieces, It is an object of the present invention to make it possible to recognize it externally and to prevent a small long body from being held in an incomplete state by the same long body holder.

  According to a first aspect of the present invention for solving the above-described problem, the elongated body holder includes a pair of elastically deformable holding pieces, and the pair of holding pieces are inserted from an insertion opening between ends of the holding pieces. A long body holding structure capable of selectively holding either one of two types of long bodies having different sizes with the same long body holder by inserting into the holding space formed by At least one of the holding pieces has a projecting portion that is pushed outward from the inner surface of the holding piece by plastic deformation or breakage due to the insertion of the large-sized long body into the holding space. The long body having a large size is held by a pair of holding pieces by pushing the protruding portion out of the holding space when inserted, and the long body having a small size has the original shape. Holding protrusion and the other holding After holding the large elongated body once by the elongated body holder, all of the protrusions are pushed out of the retaining space or greatly deformed in the retaining space. Instead of a long body having a large size by the same long body holder, the long body having a small size cannot be held or is incomplete.

  According to the first aspect of the present invention, the long body holder includes a pair of elastically deformable holding pieces, and at least one of the pair of holding pieces is plastically deformed by the insertion of the large-sized long body, Or the protrusion part extruded outside the inner surface of the said holding piece by the fracture | rupture is integrally formed in the state which entered the said holding space. When holding a long body of a small size by the long body holder, when the long body of the small size is moved in the radial direction from the insertion opening and inserted into the holding space, the pair of holding pieces are After being elastically deformed slightly outward, it is restored to the original shape or almost the original shape, and the small-sized elongate body is in a state of holding the original shape with the protrusion provided on one holding piece. It is held with the other holding piece.

  On the other hand, in the case where a long body having a large size is held by the long body holder, when the long body is moved in the radial direction from the insertion opening and inserted into the holding space, the pair of holding pieces are The protrusion provided on one holding piece after being elastically deformed to the outside and inserting a part of the long body into the holding space, as compared with the case of holding the small body having a small size. Press. Since there is a limit to the elastic deformation of the other holding piece to the outside, the protruding portion is plastically deformed or broken by the pressing force, thereby further inserting a long body having a large size into the holding space. The pair of holding pieces that are greatly elastically deformed outside is restored to the original shape or a shape close to this by elastic restoring force, so that a large elongated body is attached to one holding piece. The provided protruding portion is held by the pair of holding pieces in a state where the protruding portion is pushed outward from the inner surface of the one holding piece by plastic deformation or fracture.

  In the above, a long body having a large size is held by the pair of holding pieces in a state where the protruding portion provided on the one holding piece is pushed outward from the inner surface of the one holding piece by plastic deformation or fracture. However, it is assumed that a long body having a small size should be held with respect to the long body holder, and a long body having a large size is erroneously held. In this case, in a state in which the large body is removed from the long body holder, that is, in a state where the long body is not held by the long body holder, the one holding piece protrudes. It can be clearly seen from the appearance that the portion is greatly pushed outward from the inner surface of the one holding piece by plastic deformation or fracture. Thereby, it turns out that the said long body holder has hold | maintained the large-sized long body once, ie, hold | maintains the small-sized long body is impossible or incomplete. For this reason, the long body holder whose protrusion is pushed out from the inner surface of one holding piece cannot hold a small body, so it is discarded on the spot and a new long body is held. Hold the small long body firmly with the tool. As a result, it is possible to prevent the small-sized long body from being used for incomplete holding by the long-sized body holder once erroneously held the large-sized long body. The long body is always firmly held by a long body holder having the same structure.

  According to a second aspect of the present invention, the elongated body holder includes a pair of elastically deformable holding pieces, and the inside of the holding space formed by the pair of holding pieces from an insertion opening between the ends of the holding pieces. Is a long body holding structure capable of selectively holding any one of three types of long bodies having different outer diameters with the same long body holder, and is attached to both of the pair of holding pieces. Is a state in which the protruding portion to be pushed out or cut out from the inner surface of the holding piece by the plastic deformation due to the insertion of the long body of the maximum or intermediate size, or the fracture, or to be cut off enters the holding space. The elongated body of the maximum size is held by the inner surfaces of the pair of holding pieces by pushing out or cutting all of the protrusions out of the holding space when inserted, A long body of size is provided on each holding piece Further, the medium-sized elongated body is held by the protruding portion, and only the protruding portion provided on one of the pair of holding pieces is pushed out or cut out from the holding space, thereby the inner surface of the one holding piece. And a protrusion provided on the other holding piece, and once the maximum or intermediate size long body is once held by the long body holder, all or a part of the protrusion is Extruded to the outside of the holding space, or excised and replaced with the maximum or intermediate size of the long body by the same long body holder, and the minimum size of the long body cannot be held or is incomplete It is the structure which becomes.

  The invention of claim 2 is characterized in that protrusions are provided on both of the pair of holding pieces constituting the long body holder, and any one of the three types of long bodies can be selected and held. Different from the first invention. The longest body of the maximum size is held by the inner surfaces of the pair of holding pieces by pushing out all the protrusions provided on the pair of holding pieces to the outside or by cutting. The longest body of the minimum size is held by each protrusion provided on each holding piece. Further, the long body of the intermediate size pushes only the protruding portion provided on one of the pair of holding pieces to the outside from the holding space or cuts the inner size of the one holding piece and the other holding piece. It is hold | maintained by the provided protrusion part.

  Therefore, after holding the long body of the maximum or intermediate size once by the long body holder, both or one of the two protrusions described above is pushed out of the holding space or cut out. Since it can be seen from the appearance, it is possible to prevent the long member of the minimum size to be replaced with the long member of the maximum or intermediate size by the same long member holder from being held in an incomplete state.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the elongated body is a tube having a circular cross section, and the inner surfaces of the pair of elongated body holding pieces are outside the large size or maximum size tube. It is characterized by being formed in an arc surface corresponding to the diameter.

  The invention of claim 3 is the invention of claim 1 or 2, wherein the elongated body is a highly versatile circular tube, and the inner surfaces of the pair of elongated body holding pieces have a large size or a maximum size. Therefore, the stability of holding a large-size or maximum-size tube is enhanced.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the protruding portion is integrally formed on a side portion of the holding piece close to the insertion opening.

  According to the invention of claim 4, since the protruding portion is formed in the holding piece near the insertion opening, the long body inserted from the insertion opening toward the holding space is partially in the holding space. Immediately after is inserted, it hits the protrusion. For this reason, in the case of a long or large size elongated body, it becomes easy to elastically deform the holding piece provided with the projecting portion while plastically deforming or breaking the projecting portion. In the case of this long body, when a part of the long body is inserted from the insertion opening toward the holding space, the long body hits the protruding portion, and the holding piece provided with the protruding portion Is slightly elastically deformed outward.

  According to a fifth aspect of the present invention, in the first aspect of the invention, the elongated body that holds an extrusion opening that allows the protruding piece, which is the protruding portion, to be pushed out of the holding space is provided on the side of one holding piece. The both ends of the projecting piece in the longitudinal direction are connected to both ends of the extrusion opening in the longitudinal direction, and are projected into the holding space, so that the large amount into the holding space. Due to the forced insertion of the elongated body of the diameter, a force including a buckling force that increases the length of each connecting portion at both ends in the longitudinal direction of the protruding piece acts on the protruding piece, The protruding piece is characterized in that it is plastically deformed or broken and is pushed out of the holding space through the pushing opening.

  According to invention of Claim 5, since the protrusion piece used as the said protrusion part is along the longitudinal direction of the elongate body to hold | maintain, the said protrusion piece and the other holding piece in which the said protrusion piece is not provided, Thus, in the case of holding a long body having a small diameter (small size), it is possible to secure a long length of the portion holding the long body in the projecting piece. It can be held stably. Further, when holding a large-diameter (large size) long body, each end of the protruding piece is connected to the holding piece when the long body is inserted into the long-body holding portion. Since a force including a buckling force that increases the length of the connecting portion acts, the protruding piece is easily plastically deformed or broken.

  The invention of claim 6 is characterized in that, in the invention of claim 1, the force required to plastically deform or break the protrusion provided on one holding piece is larger than the elastic force of each holding piece. .

  According to the invention of claim 6, in the invention of claim 1, a part of the small-sized long body is inserted from the insertion opening of the long-body holder, and the protrusion provided on the one holding piece is inserted. When hit, the force required to plastically deform or break the protrusion is greater than the elastic force of each holding piece, so that the protrusion is not deformed or broken. The other non-holding piece is elastically deformed outward, and the long body having a small size is smoothly inserted into the holding space between the pair of holding pieces.

  A seventh aspect of the present invention is a long body holder provided with the long body holding structure according to any one of the first to sixth aspects, wherein the long body holding structure according to the first to sixth aspects is a pair of holding pieces. It grasps | ascertained from the surface of the elongate body holder provided.

  According to the present invention, the long body having a large size is once held by the plastic deformation or breaking of the protrusion provided on at least one of the pair of holding pieces constituting the long body holder. That is, it is understood that the holding of the small-sized elongated body is impossible or incomplete. Therefore, the long body holder in which the protruding portion is pushed out from the inner surface of at least one of the pair of holding pieces cannot hold the small body, so it is discarded on the spot and is newly The long body holding tool securely holds a small body having a small size. As a result, it is possible to prevent a long body with a small size from being used for incomplete holding by a long body holder that has once held a large body with a large size by mistake. The long body is always firmly held by a long body holder having the same structure.

As described above, the pair of holding pieces A _11, projecting from the inner surface of one of the holding pieces A ₁₁ of A ₁₂ in the holding space V ₁ piece constituting each pipe holder A ₁ of the tube holder S ₁ E ₁ Since the protruding piece E ₁ is pushed out from the extrusion opening 16 provided in the holding piece A ₁₁ when the large-diameter pipe P ₁ is inserted, the same pipe holding portion A ₁ Two types of pipes P ₁ and P ₂ having different outer diameters can be held, and the operation of holding the two types of pipes P ₁ and P ₂ with respect to the same pipe holding portion A ₁ will be described below.

First, in order to retain the small diameter pipe P ₂ relative to the tube holding portion A _1, as shown in FIG. 5, and from the pipe insertion opening 15 of the pipe holder A ₁ along the pipe P ₂ in symmetry line L ₁ When inserted into the holding space V ₁ , the pair of holding pieces A ₁₁ and A ₁₂ are slightly elastically deformed outward, and about half of the pipe P ₂ is inserted into the holding space V _{1. 2} contacts the upper end of the protruding piece E ₁ protruding from the inner surface of the holding piece A ₁₁ into the holding space V ₀ (FIG. 5A). Here, the force required to plastically deform or break the protruding piece E ₁ is larger than the force required to elastically deform the holding pieces A ₁₁ and A _12, and therefore when the tube P ₂ is further pushed in, When the holding piece A ₁₂ is deformed more greatly than the protruding piece E ₁ , the pipe P ₂ enters between the protruding piece E ₁ and the holding piece A ₁₂ (FIG. 5B), and when the pipe P ₂ is further pushed in. , holding pieces a ₁₂ which has been elastically deformed outwardly is restored to a shape close to the original shape, the pipe P ₂ is stable between the abutment surface 18 of the projecting piece E ₁ and the holding piece a ₁₂ hold (Fig. 5 (c)). Since the protruding piece E ₁ is along the longitudinal direction of the holding piece A ₁₁ (tube holding portion A ₁ ) on which the protruding piece E ₁ is provided, and the holding length for the small-diameter pipe P ₂ can be ensured long, The holding state of the small diameter pipe P ₂ is stabilized by the two protruding pieces E ₁ . The small-diameter pipe P ₂ is held in a state of being arranged asymmetrically with respect to the symmetry line L ₁ . Thus, when to hold the small-diameter pipe P ₂ relative to the pipe holder A _1, the projecting piece E _1, depending on the elastic deformation of the holding pieces A _11, together with the holding piece A ₁₁ In other words, the protruding piece E ₁ functions as a part of the holding piece A ₁₁ and holds the small-diameter pipe P ₂ in cooperation with the other holding piece A ₁₂ .

On the other hand, in order to hold the large-diameter pipe P ₁ to the same pipe holder A _1, as shown in FIGS. 6 and 7, from the pipe insertion opening 15 of the pipe holder A ₁ to symmetry line L ₁ When inserted into the holding space V ₁ , the pair of holding pieces A ₁₁ and A ₁₂ are elastically deformed to the outside much larger than the case of the small diameter pipe P ₂ , and about half of the pipe P ₂ is held in the holding space V 1. When inserted into _a tube P ₂ is in contact with the protruding piece E _1, the projecting piece E ₁ is deformed outward together with the holding piece a ₁₁ [FIGS. 6 (a)]. When the tube P ₂ is further pushed in, the pair of holding pieces A ₁₁ and A ₁₂ are hardly deformed and remain in the previous deformed state, so that the protruding piece E ₁ is plastically deformed, so that the tube P ₂ is further inserted into the holding space V ₁ [FIGS. 6B and 7A]. When the tube P ₁ is further pushed in, the pair of holding pieces A ₁₁ and A ₁₂ are restored to the shape close to the original shape by the elastic restoring force, so that the projecting piece E ₁ has the connecting portions 17a and 17b at both ends. The projection piece E ₁ is further plastically deformed by a force including a buckling force that increases the length of the projection piece E ₁ , and the projection piece E ₁ is the holding piece A in the connection portion 17 b on the side where the connection force is small. _{11 is} broken, and all of the broken pieces E ₁ ′ are pushed out of the extrusion opening 16 against the inner surface of the holding piece A ₁₁ , so that the pipe P ₁ is formed on the inner surface of the pair of holding pieces A ₁₁ , A ₁₂ . It is held in close contact with almost the entire surface (FIG. 6C). The large-diameter pipe P ₁ is held in a stable state in which the pair of holding pieces A ₁₁ and A ₁₂ are arranged symmetrically with respect to the symmetry line L ₁ . Thus, when the large diameter pipe P ₁ is held by the pipe holding portion A ₁ , the protruding piece E ₁ entering the holding space V ₁ is an obstacle to the holding of the large diameter pipe P _1. to become, by extruding from the inner surface of the holding piece a ₁₁ outwardly, the large diameter pipe P ₁ is held by the pair of holding pieces a _11, a ₁₂ performing the original-holding function. As the fracture forms of protruding pieces E _1, as shown in FIG. 7 (b), by the action state of the force large diameter pipe P ₁ is on the protruding piece E _1, the projecting piece E ₁ is longitudinal It may break at the thin portion 20 at the center in the direction.

Furthermore, when the large diameter pipe P ₁ is inserted and held in the pipe holding portion A ₁ , the protruding piece E ₁ is pushed out from the inner surface of the holding piece A ₁₁ to the outside of the large diameter pipe P ₁ as described above. Instead of pushing out by the insertion force, before inserting the large-diameter pipe P ₁ , a part of the protruding piece E ₁ is still connected to the pipe holder S ₁ using a cutter. It is also possible to perform by breaking. When the projecting piece E ₁ is broken using a cutter, even when the small diameter pipe P ₂ should be held after breaking, the broken piece E ₁ ′ is pushed out from the pipe holder S _1. From the above, it can be seen in the appearance that an attempt has been made to insert the large-diameter pipe P ₁ in the past.

As a result, as shown in FIG. 8, the large-diameter pipe P ₁ should be held by the pipe holding portion A ₁ , but the small-diameter pipe P ₂ is held due to misunderstanding or carelessness. In the case where it has been made, the protruding piece E ₁ is not deformed at all. Therefore, by removing the small-diameter pipe P ₂ from the tube holding portion A _1, it is possible to hold replace the original large diameter tube P ₁ to the same pipe holder A _1.

On the contrary, as shown in FIG. 9, when the small diameter pipe P ₂ should be held by the pipe holding portion A ₁ , but the large diameter pipe P ₁ is erroneously held, Even if the large-diameter pipe P ₁ is removed from the holding portion A ₁ , the protruding piece E ₁ is plastically deformed or broken, and is not disposed at the original position in the holding space V ₁ . It is impossible to hold the small-diameter pipe P ₂ in the holding portion A ₁ . Therefore, the tube holder S _{1 that} has erroneously held the large-diameter pipe P ₁ can only be discarded or reused at the next opportunity to hold the large-diameter pipe P ₁ .

In addition, in the past, the fact that the large-diameter pipe P ₁ was mistakenly inserted into the pipe holding part A ₁ can be immediately grasped in appearance because the protruding piece E ₁ is plastically deformed or broken. The operator does not use the pipe holder S ₁ for holding the small-diameter pipe P ₂ . The substantial advantage is that the small-diameter pipe P ₂ is not held in an incomplete state, and the pipes P ₁ and P ₂ can be completely held with respect to the pipe holder S ₁ . The quality of the piping work is improved.

Further, during the insertion of the large diameter pipe P ₁ , that is, when a part of the protruding piece E ₁ is plastically deformed and a part of the protruding piece E _{1 is in} a protruding state from the inner surface of the holding piece A ₁₁ . Therefore, even when the selection of the large-diameter pipe P ₁ is noticed and the insertion of the large-diameter pipe P ₁ is stopped halfway, the pipe holder S ₁ is used for holding the small-diameter pipe P _2. The fact that it is impossible is the same as in the above case (when an error is noticed after the large-diameter pipe P ₁ is completely inserted into the pipe holding portion A ₁ ). Even when the insertion of the large-diameter pipe P ₁ is stopped halfway, the partial deformation of the protruding piece E ₁ can be clearly recognized from the appearance, and the small-diameter pipe P ₂ is held by the pipe holder S _1. It turns out that it is impossible.

10, there is shown a tube holder S ₂ of Example 2, the above-mentioned tube holder S _1, the same parts are denoted by the corresponding reference numerals, and only different portions will be explained. The tube holder S ₂ has a configuration in which protrusions E ₂ are provided along the circumferential direction at both ends in the longitudinal direction of the holding piece A ₂₁ constituting each tube holding portion A ₂ . Extrusion openings 31 are formed at both ends in the longitudinal direction of the holding piece A ₂₁ , and the extrusion openings 31 are covered with a protrusion E ₂ having a substantially trapezoidal cross section along the circumferential direction. ₂ of the top surface has a contact surface 32 that the small-diameter pipe P ₂ abuts. The protrusion E ₂ is connected to two inner surfaces facing each other along the circumferential direction of the extrusion opening 31 by a plurality of dot-like connection portions 33.

Since the connecting force of the point-like connecting portion 33 is larger than the elastic force of the pair of holding pieces A ₂₁ and A ₂₂ constituting the tube holding portion A ₂ , the protruding portion E ₂ is inserted into the small diameter tube P ₂ . In some cases, it is not broken, but when the large-diameter pipe P ₁ is inserted, it is broken by the large insertion force and pushed out from the extrusion opening 31. Therefore, the small diameter pipe P ₂ is held by the two protruding portions E ₂ provided on one holding piece A ₂₁ and the other holding piece A ₂₂ . The large-diameter pipe P ₁ is held by the pair of holding pieces A ₂₁ and A ₂₂ by breaking the protruding portion E ₂ and pushing it out from the extrusion opening 31 by the force at the time of insertion.

11, there is shown a tube holder S ₃ of the third embodiment. The tube holder S ₃ has the same formation position of the protrusion E ₃ with respect to the holding piece A _{31 as} compared with the tube holder S ₂ , but only the shape of the protrusion E ₃ is different. The protruding portion E ₃ has a truncated cone shape and covers the circular extrusion opening 34, and the upper surface thereof is a contact surface 35 with which the small diameter pipe P ₂ contacts. The protruding portion E ₃ is connected to the portion of the circular extrusion opening 34 that faces the holding space V ₃ by a dotted connecting portion 36. The holding of the large diameter pipe P ₁ and the small diameter pipe P ₂ is the same as that of the pipe holder S ₂ .

Figure 12-A and Figure 12-B, the tube holder S ₄ Example 4 is shown. The tube holder S ₄ is formed by opening a pair of projecting pieces E ₄ in the shape of an arc plate on the inner surfaces of both ends in the longitudinal direction of the pair of holding pieces A ₄₁ and A ₄₂ constituting each tube holding portion A _4. Are connected via a connecting portion 37. Since the protruding piece E ₄ has a shape such that the thickness gradually decreases from the base end to the tip end, the protruding piece E ₄ is connected to the above portions of the pair of holding pieces A ₄₁ , A ₄₂ via the dotted connecting portion 37. When the large-diameter pipe P ₁ is inserted between the pair of holding pieces A ₄₁ and A ₄₂ in this state, as shown in FIG. 12-B (c), the protruding piece E ₄ The large-diameter pipe P ₁ is held by the pair of holding pieces A ₄₁ , A ₄₂ by being always pushed outward and pushed outward from the holding space V ₄ . . The small-diameter pipe P ₂ is held by a total of two sets of protruding pieces E _{4 that} are a pair of one provided at both ends of the pair of holding pieces A ₄₁ and A ₄₂ .

Further, to hold the intermediate diameter pipe P ₃ having an outer diameter of the intermediate between the large diameter pipe P ₁ and the small diameter pipe P _2, as shown in FIG. 12-B (d), the pipe holder A ₄ When the protruding pieces E ₄ provided at both ends in the longitudinal direction of the inner surface of the holding piece A ₄₂ are bent outward by hand, and the intermediate diameter pipe P ₃ is inserted into the holding space V ₄ in this state, the intermediate diameter pipe P ₃ is held by the inner surface of one holding piece A ₄₂ and the protruding pieces E ₄ provided at both ends in the longitudinal direction of the inner surface of the other holding piece A ₄₁ . Therefore, according to the tube holder S ₄ of Example 4, three different types of pipe P ₁ outer diameters, of P _2, P ₃ holding becomes possible.

13, there is shown a tube holder S ₅ of Example 5. Tube holder S _5, the configuration in which a pair of holding pieces A _51, 3 pieces of protruding portions E ₅ along both ends in the longitudinal direction in the circumferential direction of the inner surface of the A ₅₂ constituting the pipe holder A ₅ provided It is. The protruding portion E ₅ has a predetermined length along the longitudinal direction to partially hold both ends in the longitudinal direction of the small-diameter pipe P ₂ , and can be broken by applying an impact force (breakable) ) Structure.

For this reason, when the small-diameter pipe P ₂ is inserted into the holding space V ₅ , the small-diameter pipe P ₂ is held by the protruding portions E ₅ at three circumferential positions at both ends in the longitudinal direction of the pipe holder S ₅ . On the other hand, when holding the large-diameter pipe P ₁ , the protruding portion E ₅ is folded in advance, and in this state, the pair of holding pieces A ₅₁ , A ₅₂ are elastically deformed, and the pair of holding pieces A ₅₁ , A _The large diameter pipe P ₁ is held by ₅₂ . Since the two pipes P ₁ and P ₂ are bound by the binding string inserted through the string through hole 23, the small-diameter pipe P ₂ may be held only by the plurality of protrusions E _5. It never leaves the pipe holder A _5.
