Description

  The present invention relates to a resin pipe cutting jig.

  In general, a building such as a house is provided with a rain gutter having an eaves for receiving rain water flowing down from the roof and a gutter for guiding rain water to a drain pipe through a collector or a call. . The eaves ridges and ridges are formed by cutting a substantially U-shaped ridge member or a cylindrical ridge member with a predetermined length in a side view, and connecting the obtained multiple ridge members with joints. Configured.

When cutting a scissors member to a predetermined length, a cutting jig provided with a guide part is attached to the scissors member and operated while a cutting means such as a saw is applied to the guide part. Cut perpendicular to the direction.
As such a cutting jig, a jig provided with a holding part formed so as to be able to contact the outer peripheral surface of the flange member and a flange part protruding in the radial direction from one end of the holding part is known. In addition, in order to make it possible to attach a cutting jig to the long saddle member from the outer peripheral side and improve work efficiency, it is provided with a pair of holding parts, and these holding parts can freely rotate around the connecting part in the circumferential direction A cutting jig connected to is known.

  However, even with a cutting jig provided with a pair of clamping parts as described above, when a dimensional error occurs in the outer diameter of the flange member, a gap is generated between the flange member and the flange member when mounted on the flange member. The degree of adhesion between the scissors member and the cutting jig will decrease. If it does so, since a scissors member will become easy to shift | deviate to an axial direction at the time of a cutting | disconnection, while the efficiency of a cutting operation falls, the cutting surface of a scissors member becomes difficult to become perpendicular | vertical with respect to a longitudinal direction, and the processing precision of a scissors member falls.

Then, the cutting jig which can be shared by the eaves member from which an outer diameter differs is examined.
For example, in Patent Document 1, each end of a semi-arc-shaped strip-shaped first sandwiching portion and a second sandwiching portion is connected by a hinge, and a side surface of the first sandwiching portion and the second sandwiching portion is used for a cutting blade. There is disclosed a cutting jig provided with an engaging means to be installed on a cylindrical member (a collar member) while a guide member is erected. The engaging means includes a plurality of groove portions provided at the other end portion of the first holding portion and a protrusion provided at the other end portion of the second holding portion. The other end of the second clamping part is formed by an arcuate recess, and a protrusion is provided at the tip of the arcuate recess. At the other end of the first clamping part, an arcuate convex part that fits with the arcuate concave part is formed, and a plurality of groove parts are formed along the outer edge of the arcuate convex part.
Further, in this cutting jig, the first clamping part and the second clamping part are provided in the vicinity of the other end parts of the first clamping part and the second clamping part as means for pulling the projection part to the engagement position of the desired groove part. A finger hanging plate for connecting each of the portions and the guide member is provided.

JP 2009-285741 A

However, the configuration of the cutting jig described in Patent Document 1 is complicated, and there is a problem that it takes time to manufacture the cutting jig.
Further, when the cutting member is operated while applying a cutting means to the guide portion and a cutting member such as a resin tube is cut perpendicularly to the longitudinal direction, a large load is applied to the cutting member. If even a slight gap is generated, the flange member is likely to be displaced in the axial direction with respect to the cutting jig. Therefore, in the cutting jig described in Patent Document 1, even if the protrusion is engaged with the groove that fits the flange member, or even when a set of reinforcing materials provided as a finger hanging plate is drawn, There was a possibility that the degree of adhesion with the heel member would be insufficient.
Further, in the cutting jig described in Patent Document 1, if the diameter of the flange member has a slight or large gap with respect to the inner diameter of the holding portion that can be handled by switching the groove portion that engages the protruding portion, the cutting jig is cut. There is a problem that the degree of adhesion between the tool and the heel member is reduced, and even if a dimensional error occurs in the outer diameter of the heel member, it cannot be handled.
If the degree of adhesion between the cutting jig and the scissors member is insufficient or lowered as described above, the cutting jig cannot be reliably fixed to the scissors member, and the scissors member is likely to be displaced in the axial direction with respect to the cutting jig. Thereby, the efficiency of cutting operation of the scissors member is reduced, and the cutting surface of the scissors member is difficult to be perpendicular to the longitudinal direction, and linearity is not obtained when the scissors members are connected to each other. Connection strength and aesthetics of the connection structure will be reduced.

  The present invention has been made in view of the above circumstances, has a simple configuration, and can be securely fixed by being firmly attached to a resin pipe to be cut, and a dimensional error has occurred in the outer diameter of the resin pipe. However, it is an object to provide a usable cutting jig.

The resin tube cutting jig of the present invention includes a cylindrical portion through which a long resin tube is inserted, and at least a part of the cylindrical portion extends from the other end opposite to the one end to the one end. The pressing part which can be elastically deformed toward the inner hole of the said cylindrical part is formed by cutting away toward the said cylindrical part, It is characterized by the above-mentioned.
As described above, since the pressing portion is constituted by a part of the peripheral surface of the cylindrical portion, the resin tube cutting jig of the present invention has a complicated mechanism for tightly attaching the pressing portion to the resin tube. It is simply configured without providing. Therefore, the manufacturing time of the cutting jig is shortened.
Further, after the resin tube is inserted into the cylindrical portion, the pressing portion is pressed toward the inner hole of the cylindrical portion to be elastically deformed, whereby the degree of adhesion of the inner peripheral surface of the pressing portion to the outer peripheral surface of the resin tube Changes continuously, and a slight gap does not remain between the inner peripheral surface of the pressing portion and the outer peripheral surface of the resin tube, and the pressing portion strongly adheres to the resin tube. Therefore, even if a dimensional error occurs in the outer diameter of the resin tube and the amount is slightly increased or decreased from the predetermined outer diameter, the elastic deformation amount of the pressing portion can be easily adjusted accordingly, and the pressing portion is firmly attached to the resin tube. Is possible.

In the resin pipe cutting jig of the present invention, it is preferable that a slip stopper is provided on the inner peripheral surface of the pressing portion.
According to the above configuration, when the pressing portion is pressed toward the inner hole of the cylindrical portion and elastically deformed, the anti-slip sticks strongly to the outer peripheral surface of the resin tube, and the axial direction of the resin tube with respect to the cutting jig The deviation is effectively suppressed.

In the resin tube cutting jig according to the present invention, it is preferable that the anti-slip member is constituted by a protrusion provided on an inner peripheral surface of the pressing portion.
According to the above configuration, when the pressing portion is pressed toward the inner hole of the cylindrical portion and elastically deformed, the pressing force is concentrated on the tip of the protrusion, and the tip of the protrusion is more closely attached to the outer peripheral surface of the resin tube. And the shift | offset | difference of the axial direction of the resin pipe with respect to a cutting jig is suppressed more effectively.

Moreover, in the resin tube cutting jig of the present invention, it is preferable that the anti-slip material is composed of an elastic body adhered to the inner peripheral surface of the pressing portion.
According to the above configuration, when the pressing portion is pressed toward the inner hole of the cylindrical portion and elastically deformed, the elastic body is in close contact with the outer peripheral surface of the resin tube, and the elastic body is in contact with the resin tube ( That is, the shear stress on the inner peripheral surface of the pressing portion and the outer peripheral surface of the resin tube is increased, and the axial displacement of the resin tube with respect to the cutting jig is more effectively suppressed.

The resin tube cutting jig of the present invention includes a jig body having a cylindrical portion through which a long resin tube is inserted, and an inner peripheral surface of the cylindrical portion that is fixed to the outer peripheral surface of the resin tube. And a stopper member for locking the jig main body to the resin tube by locking from the other end side opposite to the one end.
As described above, the resin tube cutting jig of the present invention includes a jig main body, and a stopper member that can be tightly adhered to the jig main body if the jig is engaged with the inner peripheral surface of the cylindrical portion of the jig main body. By comprising, it is comprised simply, without providing the complicated mechanism for closely_contact | adhering to a resin pipe | tube. Therefore, the manufacturing time of the cutting jig is shortened.
In addition, when the stopper member is locked to the inner peripheral surface of the cylindrical portion from the other end side after the resin tube is inserted into the cylindrical portion, the stopper for the outer peripheral surface of the resin tube according to the insertion depth of the stopper member The contact degree of the member continuously changes, and the stopper member strongly adheres to the resin tube without leaving a slight gap between the inner peripheral surface of the stopper member and the outer peripheral surface of the resin tube. And by adjusting the depth at which the stopper member is locked with respect to the cylindrical portion, the degree of adhesion of the stopper member to the resin tube is easily adjusted, and even for a resin tube having a dimensional error in the outer diameter. The stopper member can be firmly attached to the resin tube.

In the resin tube cutting jig of the present invention, it is preferable that the stopper member includes an elastic body.
According to the above configuration, when the stopper member is locked to the inner peripheral surface of the cylindrical portion from the other end side, the stopper member provided with the elastic body is in close contact with the outer peripheral surface of the resin tube, and the elastic body is the resin. The shear stress on the surface in contact with the tube (that is, the surface in which the stopper member and the outer peripheral surface of the resin tube are in contact) is increased, and the displacement of the resin tube in the axial direction with respect to the cutting jig is more effectively suppressed.

In the resin tube cutting jig of the present invention, the stopper member is disposed in the circumferential direction of the resin tube and attached to the resin tube, and one side in the width direction of the attachment portion It is preferable to include an engaging portion that protrudes from the end and that gradually decreases in thickness in the protruding direction.
According to the above configuration, when the attachment portion of the stopper member is arranged and attached in the circumferential direction of the resin tube, the engagement portion of the stopper member is arranged on the circumferential surface of the resin tube, and the thickness dimension of the engagement portion Gradually decreases in the axial direction of the resin tube. For this reason, when the locking portion is inserted from the tip having the smallest thickness dimension between the other end of the cylindrical portion through which the resin tube is inserted and the resin tube, the outer peripheral surface of the locking portion becomes the inner periphery of the cylindrical portion. The inner peripheral surface of the locking portion is in close contact with the outer peripheral surface of the resin tube. And, as the locking part is inserted deeper, the degree of adhesion of the locking part to the tubular part and the resin tube continuously increases, and there is a slight difference between the inner peripheral surface of the locking part and the outer peripheral surface of the resin pipe. There is no gap left, and the locking portion is in close contact with the cylindrical portion and the resin tube. And by adjusting the depth at which the locking portion is inserted between the cylindrical portion and the resin tube, the degree of adhesion of the locking portion to the resin tube can be easily adjusted, and resin tubes having different outer diameters. In contrast, the stopper member can be firmly attached to the resin tube.

Further, in the resin pipe cutting jig of the present invention, a locked portion that can be locked by inserting the locking portion is formed at the other end opposite to the one end of the cylindrical portion. It is preferable.
According to the above configuration, the locking portion can be inserted from the tip to the locked portion at the other end of the cylindrical portion through which the resin tube is inserted and inserted between the resin tube and the cylindrical portion. The locking part is positioned in the circumferential direction of the part.

In the resin pipe cutting jig of the present invention, as described above, the pressing portion is pressed toward the inner hole of the cylindrical portion, or the stopper member is locked to the inner peripheral surface of the cylindrical portion from the other end side. Thereby, a press part or a stopper member closely_contact | adheres to a resin pipe | tube strongly. In addition, the pressing portion against the resin tube is adjusted by adjusting the amount of deformation for elastically deforming the pressing portion by pressing the pressing portion toward the inner hole of the cylindrical portion, or the depth at which the stopper member is locked. Alternatively, the degree of adhesion of the stopper member can be easily adjusted.
Therefore, according to the present invention, it has a simple configuration, can be firmly fixed by being in close contact with the resin pipe to be cut, and can cope with the case where a dimensional error occurs in the outer diameter of the resin pipe. Tools are provided.

  Hereinafter, a resin tube cutting jig (hereinafter simply referred to as a cutting jig) to which the present invention is applied will be described with reference to the drawings. The drawings used in the following description are schematic, and the length, width, thickness ratio, and the like are not necessarily the same as the actual ones, and can be changed as appropriate.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a cutting jig 1 of the present embodiment. 2 and 3 are enlarged views of a part of the cutting jig 1, and are perspective views showing an example of the configuration of the E region shown in FIG.

  As shown in FIG. 1, the cutting jig 1 according to the present embodiment includes a cylindrical portion 11 through which a resin tube (not shown) is inserted into an inner hole H, and a flange portion 13 provided continuously with one end 11 a of the cylindrical portion 11. And.

  The resin tube is a member formed in a long shape, and is, for example, a rod formed in a cylindrical shape so as to be installed in a substantially vertical direction on the outer wall of a building supported by a rod support tool or the like. . Since the scissors are installed with the axis line oriented substantially in the vertical direction, the cut surface is perpendicular to the longitudinal direction when the resin is cut to a predetermined length, and the obtained resin having a predetermined length is obtained. It is required that high linearity be obtained when the tubes are connected to each other. Therefore, in the present embodiment, the following description will be made on the assumption that the resin pipe is a ridge.

  The resin tube is made of, for example, a polyvinyl chloride resin, but the resin constituting the resin tube is not limited to the polyvinyl chloride resin. In addition, it is preferable that the light-resistant resin layer like AES resin or ASA resin is coat | covered on the outer peripheral surface of the pipe material which consists of polyvinyl chloride resin from the point which improves the weather resistance of a soot. The resin tube is formed by, for example, an extrusion method.

  The cylindrical part 11 functions as a clamping part for clamping and fixing the resin tube in the cutting jig 1, and is constituted by a cylindrical member. In order to allow the resin pipe to be inserted into the inner hole H, the inner diameter of the cylindrical portion 11 is formed to be approximately equal to the outer diameter of the resin pipe or slightly larger than the outer diameter of the resin pipe in accordance with the shape of the resin pipe. Has been.

  On the peripheral surface of the resin pipe, which is a saddle, ribs are provided which are sandwiched by a saddle support or the like when constructed in a building and extend in the longitudinal direction of the resin pipe. The cylindrical portion 11 is provided with a rib accommodating portion 19 in which the rib is accommodated when the resin tube is inserted. Thus, the cylindrical part 11 is formed according to the shape of the resin tube.

At least a part of the cylindrical portion 11 is a pressing portion 15.
In the present embodiment, the cylindrical portion 11 is notched from the other end 11b toward the one end 11a, thereby forming a pair of notches 17A and 17B that open to the other end 11b side and whose bottom end reaches the one end 11a. The pressing portion 15 is provided between the notches 17A and 17B in the circumferential direction of the cylindrical portion 11.

The pressing portion 15 can be elastically deformed toward the inner hole H of the cylindrical portion 11.
In this embodiment, after inserting the resin tube into the inner hole H, the tip 15a of the pressing portion 15 is directed toward the inner hole H (that is, in the direction of the arrow shown in FIG. 1) using a finger, a pressing instrument, or the like. When pressed, the pressing portion 15 is elastically deformed, and the inner peripheral surface 15d of the pressing portion 15 is in close contact with the outer peripheral surface of the resin tube, so that the pressing portion 15 is fixed to the resin tube.

In order to further increase the degree of adhesion of the pressing portion 15 to the resin tube, it is preferable that a slip stopper 21 is provided on the inner peripheral surface 15d of the pressing portion 15.
As shown in FIG. 2 and FIG. 3, the slip stopper 21 may be configured by, for example, a protrusion 23 provided on the inner peripheral surface 15 d, and is configured by an elastic body 25 attached to the inner peripheral surface 15 d. It may be made, and may be comprised of what has other antiskid effects.

  In the example of the slip stopper 21 shown in FIG. 2, for example, three protrusions 23 are provided on the inner peripheral surface 15 d of the pressing portion 15. The protrusions 23 are formed so as to extend in the extending direction of the cylindrical portion 11, but may be formed in a circular shape in a plan view, for example, and may be formed in a plurality at a predetermined interval on the inner peripheral surface 15 d. . Further, when the pressing portion 15 is pressed toward the inner hole H, the pressing force is concentrated on the tip 23e of the protrusion 23 and is applied to the resin tube. Therefore, the protrusion 23 is directed at least toward the inner hole H in the pressing portion 15. In this embodiment, it is formed at the distal end portion 15a on the other end 11b side of the cylindrical portion 11.

  Further, in the example of the slip stopper 21 shown in FIG. 3, an elastic body 25 made of, for example, synthetic rubber is attached to the inner peripheral surface 15 d of the pressing portion 15. Examples of the synthetic rubber include polybutadiene, nitrile, and chloroprene. Since the pressing force is applied to the resin pipe from the inner peripheral surface 25d of the elastic body 25 when the pressing portion 15 is pressed toward the inner hole H, the elastic body 25 is at least toward the inner hole H in the pressing portion 15. It is preferably formed at a position where it is pressed more strongly, and in this embodiment, it is formed at the distal end portion 15a on the other end 11b side of the cylindrical portion 11.

  As shown in FIG. 1, a protrusion 27 for supporting the resin tube in the inner hole H more stably is formed on the inner peripheral surface 11 d of the cylindrical portion 11. From the viewpoint of facilitating insertion of the resin tube into the inner hole H, the inner peripheral surface 27d of the projection 27 on the flange portion 13 side (that is, the upper end surface of the projection 27) is lowered toward the one end 11a of the cylindrical portion 11. Is formed.

  The length T of the cylindrical portion 11 and the circumferential width W (the length of the arc) of the pressing portion 15 are easy to press when the pressing portion 15 is pressed toward the inner hole H by a finger or a pressing instrument. In consideration of the above, it is preferable to set the base end portion 15b in consideration of the elastic coefficient of the material of the cylindrical portion 11 so that the base end portion 15b is not broken due to a load when the pressing portion 15 is strongly pressed. .

  The cylindrical portion 11 is made of an elastically deformable material from the viewpoint that the pressing portion 15 can be pressed toward the inner hole H, and is made of, for example, polyvinyl chloride resin, polycarbonate resin, or the like.

  The flange portion 13 is a guide member for cutting the resin pipe perpendicularly to the longitudinal direction by operating by applying a cutting means such as a saw, and the diameter of the cylindrical portion 11 from one end 11a of the cylindrical portion 11. Overhang in the direction. The shape of the flange part 13 and the overhanging dimension from the cylindrical part 11 are not particularly limited as long as the cutting means can be stably applied. In addition, the guide surface 13a for applying the cutting means to the flange portion 13 may be subjected to a flattening process or the like for the purpose of reducing friction with the cutting means, for example.

  The flange portion 13 is made of the same material as that of the cylindrical portion 11 and may be formed integrally with the cylindrical portion 11 by an extrusion method or the like, and abuts the cutting means such as stainless steel. It is comprised from the material which is made to operate | move easily and may be joined to the one end 11a of the cylindrical part 11 by welding etc. FIG.

When cutting a resin tube using the cutting jig 1, first, a long resin tube is inserted through the inner hole H of the cylindrical portion 11. At this time, the guide surface 13a of the flange portion 13 is aligned with a predetermined cutting position of the resin pipe.
Subsequently, the pressing portions 15 that make a pair with a finger or a pressing instrument are brought close to each other, whereby the pressing portions 15 are pressed toward the inner hole H to be elastically deformed. At this time, the pressing portion 15 is pressed as tightly as possible to the resin tube and is brought into close contact therewith.
Thereafter, the resin tube can be cut by operating the cutting means such as a saw against the guide surface 13a.

  As described above, the cutting jig 1 according to the present embodiment includes the cylindrical portion 11 through which a long resin pipe is inserted, and the flange portion that protrudes from the one end 11a of the cylindrical portion 11 in the radial direction of the cylindrical portion 11. 13, and at least a part of the cylindrical portion 11 is a pressing portion 15 that is elastically deformable toward the inner hole H when the cylindrical portion 11 is cut away from the other end 11 b toward the one end 11 a. Is formed.

As described above, the cutting jig 1 is constituted by a part of the peripheral surface of the cylindrical portion 11 without the need for a new complicated mechanism for strongly adhering to the resin tube, It is configured simply. Thereby, it becomes easy to manufacture the cutting jig 1, and the manufacturing time of the cutting jig 1 is also shortened.
According to the above configuration, the inner periphery of the pressing portion 15 with respect to the outer peripheral surface of the resin tube is formed by inserting the resin tube through the tubular portion 11 and then elastically deforming the pressing portion 15 by pressing the pressing portion 15 toward the inner hole H. The degree of adhesion of the surface 15d changes continuously, and there is no slight gap left between the inner peripheral surface 15d of the pressing portion 15 and the outer peripheral surface of the resin tube, and the pressing portion 15 strongly adheres to the resin tube. Fixed. Accordingly, even if a dimensional error occurs in the outer diameter of the resin tube and the amount is slightly increased or decreased from the predetermined outer diameter, the elastic deformation amount of the pressing portion 15 can be easily adjusted accordingly, and the pressing portion 15 is firmly attached to the resin tube. It becomes possible to make it.
In the configuration of the cutting jig 1 illustrated in FIG. 1, the proximal end portion 15 b of the pressing portion 15 is connected to the one end 11 a of the cylindrical portion 11 and the distal end portion 15 a is released, so that it goes toward the inner hole H. The movable range of the pressing portion 15 increases in the direction. For this reason, the adjustment range of the degree of adhesion of the pressing portion 15 with respect to the resin tube is widened, so that the pressing portion 15 can be tightly adhered to the resin tube even if the outer diameter of the resin tube varies greatly.

  Therefore, the cutting jig 1 can be firmly fixed to the resin pipe to be cut firmly, and can be used even when there is an error in the outer diameter of the resin pipe. The resin tube can be cut at a desired cut surface in accordance with the installation direction. Moreover, the efficiency of the cutting operation of the resin tubes is increased, linearity is obtained when the resin tubes are connected to each other, and the connection strength between the resin tubes and the aesthetics of the connection structure are increased.

  Further, in the cutting jig 1 of the present embodiment, the slip stopper 21 is provided on the inner peripheral surface 15 d of the pressing portion 15. The anti-slip 21 is preferably composed of a protrusion 23 provided on the inner peripheral surface 12d of the pressing portion 15 or an elastic body 25 attached to the inner peripheral surface 12d of the pressing portion 15.

According to the above configuration, when the pressing portion 15 is pressed and elastically deformed toward the inner hole H of the cylindrical portion 11, the anti-skid 21 closely adheres to the outer peripheral surface of the resin tube and A shift in the axial direction of the resin tube is effectively suppressed.
In the case where the slip stopper 21 is constituted by the protrusion 23, when the pressing portion 15 is pressed toward the inner hole H of the cylindrical portion 11 and elastically deformed, the pressing force is concentrated on the tip 23e of the protrusion 23, and the protrusion The tip 23e of the resin 23 is more closely attached to the outer peripheral surface of the resin tube, and the displacement of the resin tube in the axial direction with respect to the cutting jig 1 is more effectively suppressed.
Further, when the slip stopper 21 is constituted by the elastic body 25, when the pressing portion 15 is pressed toward the inner hole H of the cylindrical portion 11 and elastically deformed, the elastic body 25 is placed on the outer peripheral surface of the resin tube. The shear stress on the surface where the elastic body 25 comes into close contact with the resin tube (that is, the surface where the inner peripheral surface of the pressing portion and the outer peripheral surface of the resin tube contact) is increased, and the axial direction of the resin tube relative to the cutting jig 1 The shift is suppressed more effectively.

  In addition, in FIG. 1, the cutting jig 1 provided with the two press parts 15 and 15 provided in the diameter both ends of the cylindrical part 11 is illustrated. However, it is only necessary that the pressing portion 15 can be pressed from any position on the peripheral surface of the cylindrical portion 11 toward the center of the inner hole H. Depending on the relative arrangement of the pressing portion 15 with respect to the resin tube in a cross-sectional view. For the purpose of enabling the pressing portion 15 to be easily pressed, for example, one pressing portion 15 may be provided along the peripheral surface of the cylindrical portion 11, and three or more pressing portions 15 are provided at intervals. Also good.

  FIG. 1 illustrates a cutting jig 1 including a pressing portion 15 having a constant width dimension in the axial direction of the cylindrical portion 11. However, for the purpose of facilitating contact with a finger or a pressing instrument, the width of the pressing portion 15 may be continuously increased from the proximal end portion 15b toward the distal end portion 15a, and from the proximal end portion 15b to the distal end. It may be constant until it reaches the part 15a, may be enlarged from there, and may be formed in other shapes.

(Second embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
4 to 6 are perspective views showing some components of the resin tube cutting jig 2 (hereinafter, simply referred to as the cutting jig 2) of the present embodiment.
In addition, in the component of the cutting jig 2 of this embodiment shown in FIGS. 4-7, about the same component as the component of the cutting jig 1 of 1st embodiment shown in FIGS. 1-3, it is the same. The description is omitted.

  The cutting jig 2 of the present embodiment includes a jig body 31 shown in FIG. 4 and a stopper member 33 shown in FIGS. 5 and 6. As shown in FIG. 4, the jig body 31 includes a cylindrical portion 11 for inserting a resin tube (not shown) through the inner hole H and one end of the cylindrical portion 11, as in the cutting jig 1 of the first embodiment. Unlike the cutting jig 1 of the first embodiment, the cylindrical portion 11 is not provided with the pressing portion 15, although the flange portion 13 projecting from the radial direction of the cylindrical portion 11 from 11 a is provided. The jig body 31 includes a locked portion 39 described later.

The cutting jig 2 includes a stopper member 33 instead of the pressing portion 15 of the cutting jig 1 of the first embodiment. The stopper member 33 is a member that can be attached to and detached from the outer peripheral surface of the resin tube, and is locked to the inner peripheral surface 11d of the cylindrical portion 11 from the other end 11b side to fix the jig body 31 to the resin tube. It is a member.
As shown in FIG. 5 and FIG. 6, the stopper member 33 is, for example, an attachment portion 35 that can be attached to and detached from the outer peripheral surface of the resin tube, and the inner peripheral surface 11 d of the cylindrical portion 11 by the attachment portion 35. And a locking portion 37 that locks the jig main body 31 to the resin tube.

In the example of the stopper member 33 shown in FIG. 5, the stopper member 33 </ b> A protrudes from the attachment portion 35 formed in a belt shape so as to draw an arc along the outer peripheral surface of the resin tube and the side end 35 c of the attachment portion 35. And an engaging portion 37 provided. The locking portion 37 is formed in a wedge shape in a side view so that the thickness dimension gradually decreases in a direction protruding from the side end 35c, for example.
Since it is easy to attach to and detach from the outer peripheral surface of the resin tube and is locked to the inner peripheral surface 11d of the cylindrical portion 11 from the other end 11b side to increase the close contact with the inner peripheral surface 11d, the attachment portion 35 of the stopper member 33A and Examples of the material constituting the locking portion 37 include synthetic rubber having excellent elasticity. In addition, the material of the attachment part 35 and the material of the latching | locking part 37 may be the same, and may differ from the said viewpoint.
