[0046] 1. Composition of peeling tools

[0047] The peeling tool 10 involved in this utility model is a tool used to peel off the covering portion W2 of the covering line W. For example... Figure 11 As shown, the coated wire W includes a core wire W1 formed of a conductive material, and a coating portion W2 is provided to cover the core wire W1. The material of the coating portion W2 can typically be a synthetic resin such as polyvinyl chloride or polyethylene, or a synthetic rubber. The peeling tool 10 according to this invention is used, for example, to peel by using... Figure 1 The locking part 62 of the peeling tool 10 shown rotates, causing the front end 30b of the blade 30 of the peeling tool 10 to bite into the covering part W2, and peeling off the covering part W2 without damaging the core wire W1.

[0048] like Figures 1 to 3 As shown, the peeling tool 10 involved in this utility model mainly includes a wrapping wire holder 20, a blade 30 for cutting the wrapping portion W2 of the wrapping wire W, a blade holder 40 for holding the blade 30, and a support 50 for supporting the wrapping wire holder 20 and the blade holder 40.

[0049] The coating wire holder 20 is integrally formed from multiple coating wire holder parts 21 capable of holding multiple coating wires W with different diameters respectively.

[0050] The blade body 30 is held by the blade body holder 40, and the covering part W2 of the covering line W held by one of the multiple covering line holders 21 is cut off.

[0051] The support body 50 supports the wrapping line holder 20 and the blade holder 40 with the multiple wrapping line holders 21 facing the blade body 30 respectively.

[0052] The device is configured such that, with the liner holder 20 supported by the support body 50, the relative relationship between one of the plurality of liner holders 21 and the blade body 30 can be switched.

[0053] In addition to the aforementioned covering line holder 20, blade 30, blade holder 40, and support 50, the peeling tool 10 also includes a pair of blade guides 41 mounted on the blade holder 40. Furthermore, the peeling tool 10 also includes a pressing part 60 and a pressing shaft support 70 for moving the blade holder 40 forward and backward toward the covering line W.

[0054] In this utility model, the following definitions apply. Figures 1 to 3 In the peeling tool 10 shown in the diagram, the side of the wrapping line holder 20 relative to the blade holder 40 is referred to as the "upper side (upper)," and the side of the blade holder 40 relative to the wrapping line holder 20 is referred to as the "lower side (lower)." Furthermore, in this specification, the term will be... Figure 2 The frontal side shown is referred to as "front, anterior, or near-anterior". Figure 3 The back side shown is referred to as the "rear or rear side". In Figure 2 In this context, the right side is referred to as the "right side," and the left side as the "left side." Furthermore, when the covering line W is held in the covering line holder 20, the direction in which the covering line W extends is the left-right direction.

[0055] In the peeling tool 10, the wrapping line holder 20 and the blade holder 40, which holds the blade 30, are supported on their left and right sides by the support body 50, respectively, in a vertically opposite position. The pressing part 60 is located below the blade holder 40 and is supported by the pressing shaft support 70, which allows it to move freely in the vertical direction. The pressing shaft support 70 is supported by the support body 50 on the lower side of the blade holder 40.

[0056] In this embodiment, the wrapping wire holder 20, the blade holder 40, the support 50, the pressing part 60, and the pressing shaft support 70 are connected as follows.

[0057] The support body 50 includes the rotating support part 51 (described later), the fixing part 52, the first side wall 56 on the right side, and the second side wall 57 on the left side. The wrapping thread holder 20 and the pressing shaft support 70 are supported with the left and right end faces of the wrapping thread holder 20 and the pressing shaft support 70 sandwiched between the first side wall 56 on the right side and the second side wall 57 on the left side.

[0058] At a position corresponding to the center of the liner holder 20 in a side view of the first sidewall 56 and the second sidewall 57, the liner holder 20 is supported by a rotating support 51 so that it can rotate about this center. Furthermore, the fixing member 52 is configured such that its front end can be inserted into the liner holder 20 from the outer surface of the first sidewall 56 at a position off-center from the center of the liner holder 20 in a side view. The liner holder 20 is configured such that when the front end of the fixing member 52 is inserted into the liner holder 20, it becomes unable to rotate; when the front end of the fixing member 52 is removed from the liner holder 20, it becomes rotatable.

[0059] The pressing part 60 is supported by the pressing shaft support 70 between the opposing surfaces of the first side wall 56 and the second side wall 57. The blade holder 40 is supported above the pressing part 60 between the opposing surfaces of the first side wall 56 and the second side wall 57. The blade 30 is held by the blade holder 40 in a manner that allows the covering part W2 of the covering line W to be peeled off.

[0060] The blade holder 40 moves back and forth in the vertical direction as the pressing part 60 moves back and forth in the vertical direction. As the pressing part 60 moves downward away from the covering thread holder 20, the gap between the covering thread holder 20 and the blade holder 40 widens. With the gap widened, the covering thread W is placed between the covering thread holder 20 and the blade holder 40, and the pressing part 60 moves upward toward the covering thread holder 20. As a result, the covering thread W is clamped between the covering thread holder 20 and the blade holder 40. By moving the pressing part 60 further toward the covering thread holder 20, the blade 30 engages with the covering part W2. The following describes each part of the peeling tool 10.

[0061] (a) Support structure

[0062] The support body 50 supports the wrapping line holder 20, the blade body 30, the blade body holder 40, the pressing part 60, and the pressing shaft support platform 70. The support body 50 includes a rotating support part 51, a fixing part 52, and a side wall 55.

[0063] (a-1) Sidewall

[0064] like Figures 1 to 3 As shown, the sidewall 55 includes a first sidewall 56, a second sidewall 57, and a sidewall connecting member 58. The sidewall 55 supports the left and right end faces of the covering thread holder 20 and the left and right end faces of the pressing shaft support table 70, etc., sandwiched between the first sidewall 56 on the right and the second sidewall 57 on the left. Furthermore, the sidewall 55, together with the rotating support part 51 described later, supports the covering thread holder 20 so that it can rotate. Figure 8 (a) is Figure 4 A cross-sectional view of the stripping tool at line VIII-VIII. Figure 8 (b) is a cross-sectional view showing the movement of the fixed knob. Figure 2 In the front view, with the covering line holder 20 as the center, the first sidewall 56 is located on the right and the second sidewall 57 is located on the left. Both the first sidewall 56 and the second sidewall 57 are plate-shaped components, and are arranged opposite each other in the left-right direction. Furthermore, the opposing surfaces (inner surfaces) of the first sidewall 56 and the second sidewall 57 are planar along the front-back and vertical directions. In addition, the first sidewall 56 and the second sidewall 57 have a generally symmetrical shape when they are facing each other.

[0065] (a-1-1) First sidewall

[0066] like Figures 1 to 4As shown, the first sidewall 56 includes a sidewall base 56a, a sidewall upper portion 56b, and a sidewall fixing portion 56c. The sidewall base 56a is the lower portion of the first sidewall 56 relative to the central portion, and the sidewall upper portion 56b is the upper portion of the first sidewall 56 relative to the central portion. The sidewall fixing portion 56c is the rear portion of the first sidewall 56, and is the rear portion relative to the sidewall upper portion 56b.

[0067] The base 56a of the first sidewall 56 is mainly equipped with a pressing shaft support 70, which is roughly rectangular in shape when viewed from the side and extends in the vertical direction. At the lower end of the base 56a of the first sidewall 56, a plurality of support mounting holes 56j are formed, penetrating the first sidewall 56 in the thickness direction. For example... Figure 5 As shown, the pressing shaft support 70 has multiple support platform holes 70d corresponding to multiple support platform mounting holes 56j. By aligning the multiple support platform mounting holes 56j with the multiple support platform holes 70d, the support platform mounting component 70e is attached to each support platform mounting hole 56j and each support platform hole 70d, thereby achieving the desired effect. Figure 4 As shown, the pressing shaft support 70 is mounted on the first side wall 56. The right end face of the pressing shaft support 70 facing the first side wall 56 is flat, and the right end face of the pressing shaft support 70 is in contact with the opposite surface of the first side wall 56.

[0068] A liner holder 20 is mounted on the upper part 56b of the first sidewall 56, extending continuously upwards from the base 56a of the first sidewall 56, and has a generally circular shape when viewed from the side. The right end face of the liner holder 20 facing the first sidewall 56 is planar, and the right end face of the liner holder 20 is in contact with the opposite surface of the first sidewall 56.

[0069] An opening for holding the covering line W, namely the covering line holding opening 56e, is formed on the lower and front portion of the upper sidewall 56b of the first sidewall 56. The covering line holding opening 56e is formed in a generally semi-circular shape when viewed from the side by cutting off a part of the front portion of the upper sidewall 56b of the first sidewall 56.

[0070] At the central portion of the upper sidewall 56b of the first sidewall 56 in both the vertical and longitudinal directions, a dial sidewall hole 56f and a connecting member insertion hole 56g are formed, both penetrating in the plate thickness direction. The dial sidewall hole 56f is approximately circular. The connecting member insertion hole 56g is formed by two elongated holes extending from the dial sidewall hole 56f in a direction orthogonal to the plate thickness direction. The two elongated holes are symmetrical about the dial sidewall hole 56f. Furthermore, at the central portion of the upper sidewall 56b of the first sidewall 56 and the rear portion of the upper sidewall 56b (the sidewall fixing portion 56c of the first sidewall 56), a fixing knob sidewall hole 56h is formed.

[0071] The upper end of the upper portion 56b of the first sidewall 56, when viewed from the side, is formed in a semi-circular arc shape centered on the dial sidewall hole 56f. Furthermore, the front portion of the central portion in the vertical direction of the upper portion 56b of the first sidewall 56 is formed in a straight line in the vertical direction when viewed from the side. Then, the aforementioned wrapping line retaining opening 56e is formed on the lower side of this straight front portion. Additionally, along the semi-circular portion of the upper portion 56b of the first sidewall 56, a plurality of arc-shaped lightweight holes 56k extending in the thickness direction are formed.

[0072] The sidewall fixing part 56c of the first sidewall 56 is connected by the sidewall connecting part 58 described later. Figure 1 , Figure 3 , Figure 8 (a) The portion that connects the first sidewall 56 and the second sidewall 57 to each other. The sidewall fixing portion 56c of the first sidewall 56 is formed to protrude rearward from the central portion in the vertical direction relative to the upper sidewall portion 56b of the first sidewall 56. A sidewall fixing hole 56i is formed in the sidewall fixing portion 56c of the first sidewall 56. The sidewall fixing hole 56i is connected to the connecting member hole 58a1 of the sidewall connecting member 58. Figure 8 In the (a)) aligned state, the side wall fixing component 58b is embedded therein, and the side wall fixing component 58b is connected to the first side wall 56.

[0073] (a-1-2) Sidewall connecting components

[0074] Sidewall connecting member 58 connects the first sidewall 56 to the second sidewall 57. For example... Figure 8 As shown in (a), the sidewall connecting member 58 includes a connecting shaft 58a and a pair of sidewall fixing members 58b. The connecting shaft 58a is a cylindrical member extending in the left-right direction. A pair of connecting member holes 58a1 are formed at both ends of the connecting shaft 58a in the axial direction for the pair of sidewall fixing members 58b to be inserted respectively.

[0075] (a-1-3) Second sidewall

[0076] The second sidewall 57 is a component paired with the first sidewall 56. With the wrapping wire holder 20, blade 30, blade holder 40, pressing part 60, and pressing shaft support 70 sandwiched between the second sidewall 57 and the first sidewall 56, it is supported together with the first sidewall 56. The second sidewall 57 has a substantially the same structure as the first sidewall 56, so the explanation will focus on the different structures for simplicity. Figure 6 As shown, the second sidewall 57 includes a sidewall base 57a opposite to the sidewall base 56a of the first sidewall 56, a sidewall upper portion 57b opposite to the sidewall upper portion 56b of the first sidewall 56, and a sidewall fixing portion 57c opposite to the sidewall fixing portion 56c of the first sidewall 56.

[0077] Multiple support mounting holes 57j are formed at the lower end of the sidewall base 57a of the second sidewall 57. For example... Figures 4 to 7 As shown, with the multiple support mounting holes 56j, 57j, and 70d aligned, the support mounting component 70e is engaged with each support mounting hole 56j, 57j, and 70d. Thus, the pressing shaft support 70 is installed between the sidewall base 56a of the first sidewall 56 and the sidewall base 57a of the second sidewall 57. The left end face of the pressing shaft support 70 facing the second sidewall 57 is planar, and the left end face of the pressing shaft support 70 contacts the opposite surface of the second sidewall 57. Thus, with the right end face of the pressing shaft support 70 in contact with the opposing surface of the side wall base 56a of the first side wall 56, and the left end face of the pressing shaft support 70 in contact with the opposing surface of the side wall base 57a of the second side wall 57, the pressing shaft support 70 is installed between the side wall base 56a of the first side wall 56 and the side wall base 57a of the second side wall 57. Furthermore, the pressing shaft support 70 is installed in a manner that extends orthogonally relative to the opposing surfaces of the first side wall 56 and the second side wall 57.

[0078] A liner holder 20 is mounted on the upper sidewall 57b of the second sidewall 57, opposite the upper sidewall 56b of the first sidewall 56. The left end face of the liner holder 20 facing the second sidewall 57 is planar, and this left end face contacts the opposite face of the second sidewall 57. Thus, the right end face of the liner holder 20 faces the opposite face of the upper sidewall 56b of the first sidewall 56, and the left end face faces the opposite face of the upper sidewall 57b of the second sidewall 57. Furthermore, the liner holder 20 is mounted in an orthogonal direction relative to the opposite faces of the first sidewall 56 and the second sidewall 57. In this state, the liner holder 20 is supported by a rotating support 51 between the upper sidewall 56b of the first sidewall 56 and the upper sidewall 57b of the second sidewall 57, allowing it to rotate. Additionally, an opening for holding the covering line W, namely the covering line holding opening 57e, is formed on the lower and front sides of the upper side wall 57b of the second side wall 57.

[0079] A through-hole 57f is formed at the center of the upper sidewall 57b of the second sidewall 57 in both the vertical and longitudinal directions. The through-hole 57f is generally circular. When the first sidewall 56 and the second sidewall 57 are arranged opposite each other, the through-hole 57f is formed at a position corresponding to the dial sidewall hole 56f.

[0080] The upper end of the upper portion 57b of the second sidewall 57 is formed in a semi-circular arc shape centered on the hole 57f of the other sidewall when viewed from the side. Furthermore, the front portion of the central portion in the vertical direction of the upper portion 57b of the second sidewall 57 is formed in a straight line in the vertical direction when viewed from the side. Then, the aforementioned covering line retaining opening 57e is formed on the lower side of this straight front portion.

[0081] Furthermore, on the upper part 57b of the second sidewall 57, a plurality of positioning member sidewall holes 57h are formed along a circular shape centered on the other end sidewall hole 57f, and radially at positions centered on the other end sidewall hole 57f. In this embodiment, the plurality of positioning member sidewall holes 57h includes first, second, third, and fourth sidewall holes 57h1, 57h2, 57h3, and 57h4 in a circular shape that extends through the plate thickness direction. The first to fourth sidewall holes 57h1 to 57h4 are arranged to be approximately 90° apart from each other with the other end sidewall hole 57f as the center. In addition, on the upper part 57b of the second sidewall 57, a plurality of lightweight holes 56k in an arc shape extending through the plate thickness direction are formed along a circular shape centered on the other end sidewall hole 57f.

[0082] The side wall fixing part 57c of the second side wall 57 is connected by the side wall connecting part 58. Figure 1 , Figure 3 , Figure 8 (a) The portion that connects the first sidewall 56 and the second sidewall 57 to each other. A sidewall fixing hole 57i is formed in the sidewall fixing portion 57c of the second sidewall 57. The right end face of the sidewall connecting member 58 contacts the opposite face of the sidewall fixing portion 56c of the first sidewall 56, and the left end face of the sidewall connecting member 58 contacts the opposite face of the sidewall fixing portion 57c of the second sidewall 57. The sidewall fixing hole 56i, the sidewall fixing hole 57i, and the connecting member hole 58a1 of the sidewall connecting member 58 are also connected. Figure 8 Alignment is performed in (a). In this state, the first sidewall 56 and the second sidewall 57 are connected via the sidewall fixing member 58b by inserting the sidewall fixing member 58b into the sidewall fixing hole 56i of the first sidewall 56, the sidewall fixing hole 57i of the second sidewall 57, and the connecting member hole 58a1 of the sidewall connecting member 58.

[0083] (a-2) Rotary support section

[0084] The rotating support 51 is a component used to rotate the liner holder 20 around itself. The rotating support 51 is disposed in the first side wall 56, corresponding to the center of the liner holder 20 in a side view. Figure 8 As shown in (a), the rotating support 51 includes an adjustment dial 51a, a dial shaft 51b, a dial connecting component 51c, a dial shaft mounting component 51d, and a washer 51e.

[0085] The dial shaft 51b is cylindrical. The dial shaft 51b is capable of rotating around its axis (axis 28). Figure 9A Rotating around the center, the dial sidewall hole 56f of the first sidewall 56, the dial shaft insertion hole 24 of the wrapping wire holder 20 (described later), and the other end sidewall hole 57f of the second sidewall 57 are inserted in the left-right direction. A connecting hole 51b1 is formed on the dial shaft 51b in a direction orthogonal to the axial direction. Figure 8 (a) A dial connecting member 51c is inserted into the connecting hole 51b1. The dial connecting member 51c is longer than the connecting hole 51b1 and protrudes from the dial shaft 51b when inserted into the connecting hole 51b1. The dial connecting member 51c protruding from the dial shaft 51b is inserted into the connecting member engagement hole 26 of the wrapping wire holder 20, which will be described later. Thus, the dial shaft 51b and the wrapping wire holder 20 are integrally connected.

[0086] At one end of the dial shaft 51b in the axial direction, a cylindrical adjustment dial 51a is mounted, rotating integrally with the dial shaft 51b. Rotation of the adjustment dial 51a rotates the dial shaft 51b. This rotation of the dial shaft 51b allows for easy rotation of the crease holder 20. Therefore, the relative relationship between one of the plurality of crease holders 21 (described later) and the cutting edge 30 can be easily switched. Figure 8 As shown in (a), one end of the dial shaft 51b passes through the fixing knob sidewall hole 56h, and the adjusting dial 51a, which is continuous with one end of the dial shaft 51b, is as follows: Figures 1 to 4 , Figure 8 As shown in (a), it protrudes outward from the first sidewall 56. The diameter of the adjusting dial 51a is larger than the diameter of the dial shaft 51b, so one end of the dial shaft 51b is locked to the first sidewall 56 by the adjusting dial 51a.

[0087] In the adjustment dial 51a of this embodiment, it is preferable to have an indicator on its surface that allows visual identification of the type of the covering wire W of the covering wire holder 20. Preferably, the indicator displays a value corresponding to the diameter or nominal cross-sectional area of ​​the covering wire W. In this case, the operator can adjust the covering wire holder 20 to a predetermined position by rotating the adjustment dial 51a while referring to the indicator attached to it.

[0088] A dial shaft mounting hole 51b2 is formed at the other end in the axial direction of the dial shaft 51b. For example... Figure 8 As shown in (a), the dial shaft mounting component 51d is installed in the dial shaft mounting hole 51b2 with the other end of the dial shaft 51b passing through the other end of the second side wall 57 side wall hole 57f and the other end of the dial shaft 51b having a washer 51e installed from the outer side of the second side wall 57, thereby locking the other end of the dial shaft 51b to the second side wall 57.

[0089] (a-3) Fixed components

[0090] The fixing member 52 is a component that prevents the coating thread holder 20 from rotating. Specifically, the fixing member 52 is a component that can switch between a fixed state in which the coating thread holder 20 is fixed to a pair of sidewalls 55, and a fixed-release state in which the coating thread holder 20 is released from the fixation of the pair of sidewalls 55. In the fixed state, the coating thread holder 20 is supported by the pair of sidewalls 55 without rotation. In the fixed-release state, the coating thread holder 20 is supported by the pair of sidewalls 55 with rotation capability.

[0091] like Figure 8 As shown in (a), the fixing member 52 includes a fixing knob 53 and a positioning member 54. In this embodiment, as Figure 4As shown, the fixing member 52 is disposed on the side of the rotating support 51 at a position off-center from the center of the first side wall 56 (at a position off-center from the center when viewed from the side of the covering line holder 20).

[0092] The fixing knob 53 is an operating part that secures the wrapping wire holder 20 at a predetermined rotation position. The fixing knob 53 includes a grip 53a, a knob base 53b, a knob shaft 53c, a base 53d, and a base receiving part 53e. The fixing knob 53 is mounted such that it protrudes outward from the first sidewall 56 with the base receiving part 53e inserted into the fixing knob sidewall hole 56h.

[0093] The grip portion 53a is a circular component. A knob shaft 53c extends from the center of the grip portion 53a in a direction orthogonal to the radial direction (left-right direction). The knob shaft 53c has a front end portion 53c1 at its front end for insertion into and withdrawal from the retainer hole 25 of the wrapping wire retainer 20 (described later). The knob base 53b is integrally connected to and supports the grip portion 53a and the knob shaft 53c. The knob base 53b has a cylindrical shape, and in the portion of the knob shaft 53c adjacent to the grip portion 53a, it surrounds the knob shaft 53c and is connected to the grip portion 53a. To facilitate the operator's grip of the grip portion 53a, the diameter of the knob base 53b is smaller than the diameter of the grip portion 53a.

[0094] The base 53d is the part that engages with and mounts the knob base 53b. The base 53d has a cylindrical shape and includes a sliding contact portion for sliding contact with the inner wall of the knob base 53b, and a stepped portion that continues the sliding contact portion in a direction away from the knob base 53b. Figure 8 As shown in (b), when the grip 53a moves in the left-right direction, the knob base 53b slides along the sliding contact portion of the base 53d in the left-right direction. When the grip 53a moves to the side closest to the first sidewall 56, the knob base 53b abuts against the stepped portion of the base 53d and is stably supported. On the base 53d, a knob insertion hole 53d1 is formed in its center, through which the knob shaft 53c can be inserted.

[0095] The pedestal receiving portion 53e is integrally mounted with the pedestal 53d and has a cylindrical shape. A pedestal receiving hole 53e1 is formed in the center of the pedestal receiving portion 53e. The pedestal receiving portion 53e is mounted in the fixing knob sidewall hole 56h of the first sidewall 56. The pedestal 53d is fixed to the pedestal receiving portion 53e by means of communication between the knob insertion hole 53d1 and the pedestal receiving hole 53e1.

[0096] The aforementioned gripping part 53a and knob base 53b are configured to abut and separate from the base 53d and base receiving part 53e. Furthermore, in... Figure 8 As shown in (a), when the knob base 53b abuts against the base 53d, the front end 53c1 of the knob shaft 53c is inserted into the retaining body hole 25. On the other hand, in the case of... Figure 8 As shown in (b), when the knob base 53b is separated from the base 53d, the front end 53c1 of the knob shaft 53c is pulled out from the retaining body hole 25.

[0097] The positioning component 54 is an integral part of the fixing knob 53, used to fix the wrapped thread holder 20 at a predetermined rotation position. The positioning component 54 includes a ball 54a, a spring 54b, and a receiving part 54c.

[0098] The receiving portion 54c provides a receiving space for the ball 54a and the spring 54b. The receiving portion 54c is inserted into the positioning member insertion hole 27 of the wrapping wire holder 20, described later, with the receiving space opening towards the second sidewall 57. One end of the spring 54b is mounted to the bottom of the receiving portion 54c, and the spring 54b exerts a force from this bottom towards the second sidewall 57. The ball 54a is mounted to the other end of the spring 54b. The position of the ball 54a changes relative to the second sidewall 57 due to the rotation of the wrapping wire holder 20 relative to the sidewall 55. Specifically, when the ball 54a is located in the positioning member sidewall hole 57h of the second sidewall 57, it is partially inserted into the positioning member sidewall hole 57h by the force of the spring 54b. In this case, the positioning member 54, together with the fixing member 52, fixes the wrapping wire holder 20 in a predetermined position. On the other hand, ball 54a contacts the inner wall of the second sidewall 57 when it is not located in the sidewall hole 57h of the positioning member, and is received in the receiving part 54c when the spring 54b is pressed by the pressure from the second sidewall 57. In this case, ball 54a can slide on the inner wall of the second sidewall 57, and the covering wire holder 20 becomes rotatable.

[0099] (b) Covering suture retainer

[0100] The liner holder 20, together with the blade 30, holds the liner W. The liner holder 20 is supported by a rotating support 51 between the first side wall 56 and the second side wall 57. Figure 9A (a) is the left view of the body that holds the envelope line. Figure 9A (b) to (e) are front views of the first to fourth sides of the body with the covering line held in place, viewed from the front. Figure 9B (a) to (d) are schematic diagrams showing the relationship between each covering line holding part, the blade body, and the covering line.

[0101] The crease holder 20 has a plurality of crease holder portions 21 integrally formed. Each of the plurality of crease holder portions 21, together with the blade body 30 and the blade body holder 40, can hold a plurality of creases W having various diameters. It is configured such that, with the crease holder 20 supported by the support body 50, the relative relationship between one of the plurality of crease holder portions 21 and the blade body 30 can be switched. In this embodiment, the crease holder 20 is configured to rotate about a rotation axis 28 (viewed from the side), and the relative relationship between one of the plurality of crease holder portions 21 and the blade body 30 can be switched by rotating the crease holder 20. Therefore, the crease holder 20 is supported by the rotation support 51 so that it can rotate about the rotation axis 28. The crease holder 20 will be further described below.

[0102] like Figure 9A and Figure 9B As shown, the liner holder 20 of this embodiment is formed in a block shape. A dial shaft insertion hole 24, which is circular in side view, is formed in the liner holder 20. The dial shaft insertion hole 24 is formed from the left side (… Figure 9A (a) to the right side ( Figure 9B The center of the covering line retainer 20 is oriented through the left-right direction. In the dial shaft insertion hole 24, as... Figure 8 As shown in (a), the dial shaft 51b is inserted with the rotating support 51. Therefore, the dial shaft 51b is inserted into the dial sidewall hole 56f of the first sidewall 56, the dial shaft insertion hole 24, and the other end sidewall hole 57f of the second sidewall 57. In this state, the rotating support 51 is locked to the outer surface of the first sidewall 56 by adjusting the dial 51a. Figure 4 , Figure 8 (a) is secured to the outer surface of the second sidewall 57 by means of washer 51e and dial shaft mounting component 51d. Figure 6 , Figure 8 (a)

[0103] Furthermore, such as Figure 9A As shown in (d), on the right side of the coating retainer 20, a groove-shaped connecting member engagement hole 26 is formed, extending in a direction orthogonal to the rotation axis 28 with the dial shaft insertion hole 24 as the center. The connecting member engagement hole 26 is formed by two elongated holes extending from the dial shaft insertion hole 24 in a direction orthogonal to the rotation axis 28. The two elongated holes are symmetrical about the dial shaft insertion hole 24. In the connecting member engagement hole 26, as... Figure 8As shown in (a), a dial connecting member 51c is inserted into a connecting hole 51b1 that passes through the dial shaft 51b. That is, via the dial connecting member 51c, the rotating support 51 and the wrapping thread holder 20 are connected in a manner that allows them to rotate as a single unit. In other words, while the rotating support 51 is rotated by adjusting the rotation of the dial 51a, the wrapping thread holder 20 rotates about the rotation axis 28.

[0104] The coating wire holder 20 has multiple coating wire holders 21, and the relative relationship between one of the multiple coating wire holders 21 and the blade body 30 can be switched by rotating about the rotation axis 28. The multiple coating wire holders 21 are formed to hold coating wires W of different diameters.

[0105] In this embodiment, as an example of the covering thread holding part 21, such as Figure 9A and Figure 9B As shown, a liner holder 20 has four liner holder portions 21. The four liner holder portions 21 are designated as first, second, third, and fourth liner holder portions 21a, 21b, 21c, and 21d. The first to fourth liner holder portions 21a to 21d are each formed with a generally semi-circular cross-section of different diameters. This cross-section is along both the front-back direction and the top-bottom direction. In this embodiment, the first to fourth liner holder portions 21a to 21d are formed with semi-circular shapes whose diameters increase sequentially. Furthermore, the first to fourth liner holder portions 21a to 21d extend along the left-right direction, that is, along the length direction of the liner W.

[0106] These roughly semi-circular inner surfaces face radially outward relative to the rotation axis 28. Furthermore, these roughly semi-circular inner surfaces have a recessed shape when viewed radially outward along the outer periphery of the wrapping line W, opposite the blade body 30. The first to fourth wrapping line holding portions 21a to 21d are formed by cutting off the corners of a cuboid shell, each side in the left-right, up-down, and front-back directions when viewed from the side. The right and left end faces of the wrapping line holder 20 face the opposing surfaces of the first sidewall 56 and the second sidewall 57, respectively, in the front-back and up-down directions. The first to fourth wrapping line holding portions 21a to 21d are located in four radial directions within the wrapping line holder 20, centered on the rotation axis 28 of the wrapping line holder 20. Therefore, each time the adjustment dial 51a is rotated 90°, the relative positions of the blade body 30 and the first to fourth wrapping line holding portions 21a to 21d can be different. Furthermore, in this embodiment, the direction in which the rotation axis 28 of the wrapping wire holder 20 extends is the same left-right direction as the direction in which the foremost end of the first blade front end 31b of the blade body 30 extends, and they are parallel.

[0107] The first to fourth covering line retaining portions 21a to 21d will be further explained. For example... Figure 9B As shown in (a) to (d), the first to fourth coating wire holding portions 21a to 21d are respectively configured to hold each coating wire W of different diameters together with the blade 30 in such a way that the coating portions W2 (W2a, W2b, W2c, W2d) of coating wires W (Wa, Wb, Wc, Wd) of different diameters can be peeled from the core wire W1 (W1a, W1b, W1c, W1d) by the blade 30. That is, in Figure 9B In (a), the first coating wire holding portion 21a is configured to hold the coating wire Wa together with the blade 30 in such a way that the coating portion W2a of the coating wire Wa can be peeled off from the core wire W1a by the blade 30. Figure 9B In (b), the second coating wire holding portion 21b is configured to hold the coating wire Wb together with the blade 30 in such a way that the coating portion W2b of the coating wire Wb can be peeled from the core wire W1b by the blade 30. Figure 9B In (c), the third coating wire holding part 21c is configured to hold the coating wire Wc together with the blade 30 in such a way that the coating part W2c of the coating wire Wc can be peeled off from the core wire W1c by the blade 30. Figure 9B In (d), the fourth coating wire holding part 21d is configured to hold the coating wire Wd together with the blade body 30 in such a way that the coating part W2d of the coating wire Wd can be peeled off from the core wire W1d by the blade body 30.

[0108] In other words, such as Figure 9B As shown in (a) to (d), each of the coating thread holding portions 21a to 21d is configured such that, on a side other than the side where the blade 30 contacts the coating thread W (Wa to Wd), it at least partially covers and contacts the surface of each of the plurality of coating threads W (Wa to Wd) with different diameters. Furthermore, the first to fourth coating thread holding portions 21a to 21d are radially arranged relative to the radial direction of the coating thread holding body 20 centered on the rotation axis 28, and are formed in a semi-circular arc shape with respect to the blade 30. Thus, during the period when the peeling tool 10 rotates and the blade 30 peels off the coating portion W2 of each coating thread W, each of the coating thread holding portions 21a to 21d at least partially covers and contacts the surface of the coating portion W2 of the coating thread W before it is peeled off by the blade 30.

[0109] The formation positions of each liner holding portion 21a to 21d in the liner holding body 20 are set considering the protruding length and direction of the blade 30 toward each liner holding portion 21a to 21d, the diameter of the liner W, and the thickness of the covering portion W2 of the liner W, so that the covering portion W2 can be peeled off by the blade 30. The formation positions of each liner holding portion 21a to 21d in the liner holding body 20 will be further explained below.

[0110] exist Figure 9B In (a), the first covering thread holding portion 21a is formed to hold the covering thread Wa between the front end, i.e., the top of the blade body 30 and the first covering thread holding portion 21a. The top of the blade body 30 is located in contact with the surface of the core thread W1a in such a way that the covering portion W2a can be peeled off from the core thread W1a by the blade body 30. In this embodiment, the center W0a of the covering thread Wa is the center of the arc of the first covering thread holding portion 21a, and the direction in which the center W0a extends is the same left-right direction and parallel to the direction in which the foremost end of the first blade front end portion 31b of the blade body 30 extends.

[0111] exist Figure 9B In (b), the second coating thread holding portion 21b is formed to hold the coating thread Wb between the tip (top) of the blade body 30 and the second coating thread holding portion 21b. The top of the blade body 30 is located in contact with the surface of the core thread W1b, such that the coating portion W2b can be peeled off from the core thread W1b by the blade body 30. The direction in which the center W0b of the second coating thread holding portion 21b extends is the same left-right direction as the direction in which the foremost tip of the first blade tip 31b of the blade body 30 extends, and is parallel to it. Figure 9B In (c), the third coating thread holding portion 21c is formed to hold the coating thread Wc between the tip, i.e., the top of the blade body 30 and the third coating thread holding portion 21c. The top of the blade body 30 is located in contact with the surface of the core thread W1c, such that the coating portion W2c can be peeled off from the core thread W1c by the blade body 30. The direction in which the center W0c of the third coating thread holding portion 21c extends is the same left-right direction as the direction in which the foremost tip of the first blade tip 31b of the blade body 30 extends, and is parallel to it. Figure 9B In (d), the fourth coating wire holding portion 21d is formed to hold the coating wire Wd between the front end, i.e., the top of the blade body 30 and the fourth coating wire holding portion 21d. The top of the blade body 30 is located in contact with the surface of the core wire W1d, such that the coating portion W2d can be peeled off from the core wire W1d by the blade body 30. The direction in which the center W0d of the fourth coating wire holding portion 21d extends is the same left-right direction as the direction in which the foremost end of the first blade front end portion 31b of the blade body 30 extends, and is parallel to it.

[0112] In addition, such as Figures 4 to 7 As shown, the first and second sidewalls 56 and 57 are configured such that they do not interfere with the retention of the coating line W by the first to fourth coating line holding portions 21a to 21d and the blade body 30. Specifically, the coating line holding openings 56e and 57e of the first and second sidewalls 56 and 57 have a diameter greater than or equal to the largest diameter of the coating line holding portion 21 among the first to fourth coating line holding portions 21a to 21d. Furthermore, when the coating line holding body 20 is installed on the first and second sidewalls 56 and 57, the opening edges of the coating line holding openings 56e and 57e are retracted to a position closer to the rotation support portion 51 than the edges of the first to fourth coating line holding portions 21a to 21d.

[0113] The first to fourth liner holding portions 21a to 21d are connected by planar first, second, third, and fourth surfaces 22a, 22b, 22c, and 22d, respectively. The first to fourth surfaces 22a to 22d are the planar surfaces of the block-shaped liner holding body 20 other than the first to fourth liner holding portions 21a to 21d that have not been cut off.

[0114] The fourth coating line holding part 21d is connected to the first coating line holding part 21a via a first surface 22a. When the first coating line holding part 21a is facing the blade body 30, the first surface 22a contacts the upper surface of the blade body holding body 40 in the horizontal direction. The first coating line holding part 21a is connected to the second coating line holding part 21b via a second surface 22b. When the second coating line holding part 21b is facing the blade body 30, the second surface 22b contacts the upper surface of the blade body holding body 40 in the horizontal direction. The second coating line holding part 21b is connected to the third coating line holding part 21c via a third surface 22c. When the third coating line holding part 21c is facing the blade body 30, the third surface 22c contacts the upper surface of the blade body holding body 40 in the horizontal direction. The third coating line holding part 21c is connected to the fourth coating line holding part 21d via a fourth surface 22d. With the fourth covering line holding part 21d facing the blade body 30, the fourth surface 22d contacts the upper surface of the blade body holding body 40 in the horizontal direction.

[0115] The rotation and rotation prevention of the coating thread holder 20 can be set by the fixing member 52. On the right side of the coating thread holder 20, as shown... Figure 5 As shown, a plurality of first, second, third, and fourth retaining body holes 25a, 25b, 25c, and 25d are formed corresponding to the retaining knob 53 of the retaining member 52. The first to fourth retaining body holes 25a to 25d are respectively formed at positions close to the first to fourth surfaces 22a to 22d. In addition, as Figure 4As shown, a fixing knob sidewall hole 56h is formed on the first sidewall 56 in such a manner that it corresponds to one of the first to fourth retaining body holes 25a to 25d. In other words, a fixing knob sidewall hole 56h is formed on the first sidewall 56 to lock the fixing knob 53 in place. Figure 4 The side wall hole 56h of the fixed knob corresponds to one of the first to fourth retaining body holes 25a to 25d.

[0116] On the other hand, on the left side of the covering line retainer 20, such as Figure 7 and Figure 9A As shown in (a), a positioning member insertion hole 27 is formed corresponding to the positioning member 54 of the fixing member 52. Figure 9A In example (a), the positioning member insertion hole 27 is formed at a position corresponding to the second surface 22b. Additionally, as... Figure 6 As shown, first to fourth sidewall holes 57h1 to 57h4 are formed on the second sidewall 57 in a manner corresponding to the positioning member insertion hole 27.

[0117] The rotation of the covering thread holder 20 is achieved by positioning the holding portion 53a of the fixed knob 53 in a direction away from the first side wall 56. Figure 8 (b) can be achieved by rotating the dial 51a (locked-out state). In this case, the front end 53c1 of the knob shaft 53c disengages from one of the first to fourth retaining body holes 25a to 25d (retaining body holes 25). Furthermore, the ball 54a of the positioning member 54 is configured to disengage from one of the first to fourth side wall holes 57h1 to 57h4 (positioning member side wall holes 57h) and slide on the inner wall surface of the second side wall 57.

[0118] On the other hand, rotation of the liner holder 20 is prevented by positioning the grip portion 53a of the fixing knob 53 close to the first sidewall 56. In this case, the front end 53c1 of the knob shaft 53c is inserted into the holder hole 25 (one of the first to fourth holder holes 25a to 25d), thus preventing rotation of the liner holder 20 (fixed state). Figures 4 to 7 In the example case, rotation of the coating thread holder 20 is prevented when the third coating thread holder 21c is opposite to the blade body 30. In this case, the front end 53c1 of the fixing knob 53 is inserted into the second holder hole 25b of the coating thread holder 20. On the other hand, the ball 54a of the positioning member 54 is embedded in the second sidewall hole 57h2 of the second sidewall 57.

[0119] Retaining body openings 23 (first, second, third, and fourth retaining body openings 23a, 23b, 23c, and 23d) are formed on the first to fourth surfaces 22a to 22d. The first to fourth retaining body openings 23a to 23d are recesses extending from the first to fourth surfaces 22a to 22d to a position close to the dial shaft insertion hole 24. Forming the first to fourth retaining body openings 23a to 23d allows for a lighter weight for the coated wire retaining body 20.

[0120] In the above description, the wrapping wire holder 20 is block-shaped, but the wrapping wire holder 20 is not limited to having multiple wrapping wire holding portions 21 as long as it has these. The wrapping wire holder 20 can also be, for example, cylindrical or polygonal prism-shaped. Alternatively, the wrapping wire holder 20 can be formed by bending a plate-shaped member and performing sheet metal processing to have multiple wrapping wire holding portions 21 capable of holding the wrapping wire W.

[0121] Furthermore, as described above, one liner holder 20 has four liner holder portions 21, but the number of liner holder portions 21 is not limited to four; it may be two or more, or three or more. Additionally, the first to fourth surfaces 22a to 22d are not limited to a planar shape; they may also be curved.

[0122] Furthermore, the first to fourth covering line holding portions 21a to 21d can each hold the covering line W, and their shapes are not limited to a roughly semi-circular cross-section. For example, the shapes of the first to fourth covering line holding portions 21a to 21d can also be roughly V-shaped, roughly triangular, or roughly semi-elliptical in cross-section, etc.

[0123] (c) Pressing part

[0124] The pressing part 60 causes the blade body 40 to move up and down. For example... Figures 4 to 7 As shown, the pressing part 60 includes a pressing shaft 61, a locking part 62, and a pair of guide shafts 63.

[0125] (c-1) Press the shaft

[0126] The pressing shaft 61 is located between the opposing surfaces of the first side wall 56 and the second side wall 57, and is supported on the lower side of the blade holder 40 by the pressing shaft support 70. The pressing shaft 61 is operated by the engaging part 62 to move the blade holder 40 up and down.

[0127] like Figure 5 and Figure 7As shown, the pressing shaft 61 has a pressing shaft main body 61a, a connecting part 61b, a first support part 61c, a second support part 61d, and a connecting part 61e. The pressing shaft main body 61a is formed into a cylindrical shape extending in the vertical direction, and a threaded portion is formed on its outer surface. The pressing shaft main body 61a is movably inserted into the pressing shaft threaded hole 70f of the pressing shaft support table 70 in the vertical direction. That is, a threaded groove is formed on the inner surface of the pressing shaft threaded hole 70f, and the pressing shaft main body 61a is movably inserted into the threaded groove of the pressing shaft threaded hole 70f by the threaded portion of the pressing shaft main body 61a engaging with the threaded groove of the pressing shaft threaded hole 70f, thereby allowing the pressing shaft main body 61a to move freely in the vertical direction relative to the pressing shaft support table 70.

[0128] The connecting portion 61b is continuous with the lower side of the pressing shaft main body 61a and is connected to the engaging portion 62. A connecting portion engaging hole 61b1 is formed in the connecting portion 61b, which extends in a direction orthogonal to the extending direction of the pressing shaft main body 61a. Figure 7 ).

[0129] The first support portion 61c is continuous with the upper side of the pressing shaft main body portion 61a. The second support portion 61d is continuous with the upper side of the first support portion 61c via the connecting portion 61e. The first support portion 61c and the second support portion 61d are formed into cylinders with approximately the same diameter. The connecting portion 61e is formed into a cylinder with a diameter smaller than that of the first support portion 61c and the second support portion 61d. As a result, a pivot groove 61f is formed between the first support portion 61c and the second support portion 61d.

[0130] (c-2) Engagement part

[0131] The engaging portion 62 is a component used to operate the vertical movement of the pressing shaft 61. The engaging portion 62 includes a ring portion 62a and a base portion 62b. The ring portion 62a is formed in a ring shape. The base portion 62b is a component connected to the pressing shaft 61 and is formed in a cylindrical shape extending in the vertical direction. On one side of the base portion 62b ( Figure 4 In the case of the lower side), a ring portion 62a is fixed thereon, and on the other side ( Figure 4 In the case of an opening on the upper side, the base 62b has an engaging hole 62b2 formed on its side. When the connecting portion 61b of the pressing shaft 61 is inserted into the opening on the other side of the base 62b, the rod-shaped engaging member 62b1 is inserted into the engaging hole 62b2 of the base 62b and the engaging hole 61b1 of the connecting portion of the connecting portion 61b, and the engaging portion 62 engages with the connecting portion 61b of the pressing shaft 61. Thus, by rotating the engaging portion 62, the pressing shaft 61 can be rotated simultaneously with the rotation of the engaging portion 62.

[0132] (c-3) Guide shaft

[0133] A pair of guide shafts 63 guide the vertical movement of the pressing shaft 61. Each guide shaft 63 is formed as a cylinder extending in the vertical direction. Figure 5 and Figure 7 As shown, the upper end of each guide shaft 63 is pivotally connected to the guide shaft pivot hole 40k of the blade holder 40, and the lower end is freely inserted into the guide shaft insertion hole 70g of the press shaft support 70 in the vertical direction. A pair of guide shafts 63 are arranged in the left-right direction, sandwiching the press shaft 61. By guiding the vertical movement of the press shaft 61 with the pair of guide shafts 63, the loosening of the press shaft 61 in the lateral direction can be suppressed. Therefore, while suppressing the lateral loosening of the blade holder 40, the blade holder 40 can be moved stably in the vertical direction.

[0134] (d) Blade

[0135] The blade 30 peels off the covering part W2 of the covering line W.

[0136] like Figure 1 , Figure 2 , Figures 4 to 7 As shown, the blade body 30 includes a first blade body 31, a pair of second blade bodies 32, and a blade body mounting component 33. The first blade body 31 bites into the covered portion W2 along the axial direction of the covering line W and cuts off the covered portion W2. The pair of second blade bodies 32 are disposed on both sides of the first blade body 31. The second blade body 32 on the right and the second blade body 32 on the left simultaneously bite into the covered portion W2 along the circumferential direction of the covering line W and cut off the covered portion W2.

[0137] The first cutting edge 31 is generally formed in a plate shape, with its plate-shaped surface extending along the left-right and up-down directions. Therefore, the plate-shaped surface of the first cutting edge 31 is orthogonal to the opposing surfaces of the first sidewall 56 and the second sidewall 57. The first cutting edge 31 includes a first cutting edge body 31a and a first cutting edge front end 31b. The first cutting edge body 31a is continuous with the lower side of the first cutting edge front end 31b, supporting the first cutting edge front end 31b. The first cutting edge body 31a is a cuboid shape with each side extending along the left-right, up-down, and front-back directions, having a predetermined width in the left-right direction and extending in the up-down direction. A first mounting hole 34 is formed in the first cutting edge body 31a, extending from the front side to the back side. A cutting edge mounting member 33 is inserted into the first mounting hole 34.

[0138] The front end portion 31b of the first cutting edge is continuous with the upper side of the main body portion 31a of the first cutting edge, and is the portion that peels off the covering portion W2 of the covering line W mainly along the axial direction. The width of the front end portion 31b in the front-to-back direction (thickness direction) decreases as it moves towards the upper side in the vertical direction, that is, towards the covering line W held by the covering line holding portion 21. In other words, the front end portion 31b of the first cutting edge is formed as a cone shape, where the length of the front and back sides of the front end portion 31b decreases as it moves towards the front (upper) side. Furthermore, the foremost point of the front end portion 31b extends along the left-to-right direction. With this shape, the front end portion 31b of the first cutting edge can bite into the covering line W along the axial direction of the covering line W and peel off the covering portion W2 of the covering line W. Additionally, the left-to-right length of the front end portion 31b of the first cutting edge is approximately the same as the left-to-right length of the main body portion 31a of the first cutting edge. Furthermore, the lengths of the first blade body main body 31a and the first blade body front end 31b in the left-right direction are approximately the same as the lengths of the blade body retainer main body 40b in the left-right direction in the blade body retainer 40.

[0139] Each pair of second blades 32 includes a main body portion 32a and a front end portion 32b. Each pair of second blades 32 is a plate-shaped component. A through hole (not shown) is formed on each pair of second blades 32 in a direction orthogonal to the plate-shaped surface, for screwing into a pair of guide mounting components 41d. The pair of second blades 32 are respectively disposed between the first blade 31 and each of the pair of blade guides 41 by screwing the guide mounting components 41d into the through hole. Specifically, the rightmost second blade 32 of the pair of second blades 32 is configured such that its left plate-shaped surface contacts the right end face of the first blade 31, and its right plate-shaped surface contacts the opposite surface of the rightmost blade guide 41 of the pair of blade guides 41. On the other hand, the left second blade 32 of the pair of second blade bodies 32 is configured such that the right plate-shaped surface of the second blade body 32 contacts the left end face of the first blade body 31, and the left plate-shaped surface of the second blade body 32 contacts the opposite face of the left blade guide 41 of the pair of blade guides 41.

[0140] The lower side of the second blade body main body 32a is continuous with the lower side of the second blade body front end portion 32b, supporting the second blade body front end portion 32b. The second blade body main body 32a is formed to bulge forward compared to the first blade body main body 31a. The second blade body front end portion 32b is continuous with the upper side of the second blade body main body 32a, and is the portion that peels off the covering portion W2 of the covering line W mainly along the circumferential direction. The second blade body front end portion 32b bulges out compared to the first blade body front end portion 31b in the portion continuous with the second blade body main body 32a, but the front end of the first blade body front end portion 31b coincides with the front end of the second blade body front end portion 32b. That is, the vertical position of the front end of the first blade body front end portion 31b coincides with the vertical position of the front end of the second blade body front end portion 32b.

[0141] Because the blade body 30 and the blade body holder 40 are configured to be independent, and the blade body 30 is connected to the blade body holder 40, the blade body 30 can be replaced relative to the blade body holder 40.

[0142] (e) Blade retainer

[0143] The blade holder 40 holds the blade 30. Specifically, the blade holder 40 holds the blade 30 such that the covering line W is held between the blade 30 and the covering line holding part 21 of the covering line holder 20. The blade holder 40 is supported by a pressing shaft 61 between the opposing surfaces of the first side wall 56 and the opposing surfaces of the second side wall 57, and can move freely in the vertical direction by moving the pressing shaft 61 up and down. Figure 10 (a) is a side view of the blade holder. Figure 10 (b) is a bottom view of the blade holder.

[0144] The blade holder 40 includes a blade holder base 40a, a blade holder main body 40b, and a front end 40c. The blade holder base 40a is located behind the blade holder main body 40b and is formed as a cuboid with sides extending in the left-right, up-down, and front-back directions. The length of the blade holder base 40a in the left-right direction is approximately the same as the width of the wrapping wire holder 20 in the left-right direction. A pair of concave guide shaft pivot holes 40k are formed in the blade holder base 40a, extending from the lower surface in the up-down direction and closed at the top. The pair of guide shaft pivot holes 40k are symmetrically arranged with respect to the center of the blade holder base 40a in the left-right direction. The front ends of a pair of guide shafts 63 are pivotally connected to each of the pair of guide shaft pivot holes 40k. Thus, the blade holder 40 and the pair of guide shafts 63 move integrally in the up-down direction.

[0145] The blade holder body main body 40b is continuous with the front side of the blade holder body base 40a, forming a cuboid shape with each side extending in the left-right, up-down, and front-back directions. Furthermore, the retainer front end 40c is continuous with the lower front end of the blade holder body main body 40b, forming a generally cuboid shape with each side extending in the left-right, up-down, and front-back directions. The upper surface of the blade holder body main body 40b and the upper surface of the blade holder body base 40a are approximately coplanar. The upper surface of the retainer front end 40c is located lower than the upper surface of the blade holder body main body 40b, and a stepped portion is formed between the blade holder body main body 40b and the retainer front end 40c. In this stepped portion, the blade holder body main body 40b has a blade mounting surface 40d, which serves as the front side surface of the blade holder body main body 40b. Additionally, in the stepped portion, the front end portion 40c of the retainer has a blade mounting surface 40e that serves as the upper side of the front end portion 40c of the retainer.

[0146] Here, a pair of second mounting holes 40f are formed in the main body 40b of the blade holder, facing the blade mounting surface 40d. For example... Figure 5 and Figure 7 As shown, with the back surface of the blade body 30 in contact with the blade body mounting surface 40d and the lower surface of the blade body 30 in contact with the blade body supporting surface 40e, the blade body mounting member 30c is inserted from the first mounting hole 30d into the second mounting hole 40f, thereby mounting the blade body 30 onto the blade body holder 40. The vertical length of the blade body mounting surface 40d is the length by which the front end of the blade body 30b protrudes from at least the upper surface of the blade body holder body main body 40b. Furthermore, the longitudinal length of the blade body supporting surface 40e is approximately the same as the longitudinal length of the blade body 30.

[0147] The left-right length of the blade holder base 40a is longer than the left-right length of the blade holder body 40b. When viewed directly, the center of the left-right direction of the blade holder base 40a is approximately the same as the center of the left-right direction of the blade holder body 40b. Therefore, when viewed directly, the two ends of the blade holder base 40a protrude left-right from the two ends of the blade holder body 40b, respectively.

[0148] A pair of guide mounting holes 40g are formed on the main body 40b of the blade holder, each facing the left and right sides. The pair of guide mounting holes 40g are formed near the front side of the main body 40b of the blade holder. A pair of guide mounting parts 41d for mounting the second blade 32 and the blade guide 41 (described later) to the main body 40b of the blade holder are screwed into the pair of guide mounting holes 40g.

[0149] like Figure 10As shown in (b), a cylindrical pressing shaft front end hole 40h facing the lower surface is formed in the blade holder body main body 40b. The pressing shaft front end hole 40h is a recess with a predetermined depth from the lower surface of the blade holder body main body 40b. The pressing shaft front end hole 40h is the center part in the left-right direction of the blade holder body main body 40b and is formed at a position rearward than the pair of guide mounting holes 40g.

[0150] Furthermore, a pair of anti-disengagement component insertion holes 40i are formed on the main body 40b of the blade holder, facing the left and right sides respectively. The pair of anti-disengagement component insertion holes 40i are respectively connected to the front end hole 40h of the pressing shaft, and are formed symmetrically extending in the left and right directions with the front end hole 40h of the pressing shaft as the center. Specifically, the pair of anti-disengagement component insertion holes 40i are respectively as follows... Figure 10 As shown in (b), at the center of the front and rear directions of the pressing shaft front end hole 40h, and as Figure 5 and Figure 7 As shown, the central part of the front end hole 40h of the pressing shaft is connected to the front end hole 40h of the pressing shaft in the vertical direction.

[0151] like Figure 5 and Figure 7 As shown, the front end of the pressing shaft 61 is inserted into the pressing shaft front end hole 40h. Furthermore, an anti-disengagement member 40j is inserted into the pressing shaft front end hole 40h from at least one of the pair of anti-disengagement member insertion holes 40i. The front end of the anti-disengagement member 40j protrudes into the pivot groove 61f between the first support portion 61c and the second support portion 61d of the pressing shaft 61. In other words, the anti-disengagement member 40j is supported in a manner clamped by the first support portion 61c and the second support portion 61d. Thus, the pressing shaft 61 is rotatably locked relative to the blade holder 40.

[0152] Furthermore, for example, during peeling, when the coating wire holder 20 and the blade 30 are able to hold the coating wire W, the blade holder 40 is in surface contact with the coating wire holder 20. Specifically, the upper surface of the blade holder 40 is planar and formed along the horizontal direction. When the coating wire holder 21 is set such that the desired coating wire holder 21 among the first to fourth coating wire holders 21a to 21d is opposite to the blade 30, one of the first to fourth surfaces 22a to 22d is in surface contact with the upper surface of the blade holder 40. Since the blade holder 40 is in surface contact with the coating wire holder 20 in this way, the positional relationship between the blade holder 40 and the coating wire holder 20 can be stably fixed compared to the case of point contact. Therefore, by preventing the wrapping thread holder 20 from wobbling when peeling off the wrapping portion W2 while clamping the wrapping thread W between the wrapping thread holder 20 and the blade 30, the wrapping thread W can be held stably between the wrapping thread holder 21 and the blade 30. Furthermore, the positional relationship between the blade holder 40 and the wrapping thread holder 20 can be adjusted by the amount of movement from rotating the pressing shaft 61 until the blade holder 40 comes into contact with the wrapping thread holder 20. In other words, since the positional relationship between the first to fourth wrapping thread holder portions 21a to 21d of the blade holder 40 and the wrapping thread holder 20 is adjusted by this amount of movement, the distance at which the blade 30 engages with the wrapping thread W can be adjusted.

[0153] (f) Blade guide

[0154] like Figure 1 , Figures 4 to 7 As shown, a pair of blade guides 41 are installed on the left and right sides of the blade body 30 and the blade body retainer 40, respectively. Specifically, a pair of blade guides 41 are installed in such a way that they cover the left and right outer sides of a pair of second blade bodies 32.

[0155] A pair of blade guides 41 determine the peeling position of the covering portion W2 of the covering line W, guiding the peeled covering portion W2 in a certain direction and preventing the peeled covering portion W2 from falling off. The pair of blade guides 41 are plate-shaped components.

[0156] The blade guide 41 includes a guide body 41a and a detachment prevention part 41b. A through hole (not shown) is formed in the guide body 41a. Figure 10 (b) and Figures 4 to 7 As shown, with the second blade 32 and the blade guide 41 arranged on the side of the blade holder 40, a guide mounting member 41d is inserted into the through hole (not shown) of the second blade 32 and the through hole of the blade guide 41. Furthermore, the second blade 32 and the blade guide 41 are mounted to the blade holder 40 by screwing the guide mounting member 41d into the guide mounting hole 40g of the blade holder 40.

[0157] The detachment prevention part 41b extends forward of the guide body part 41a and extends to a position higher than the guide body part 41a. By adjusting the size of the detachment prevention part 41b protruding forward and upward relative to the guide body part 41a, the position where the covering part W2 of the covering line W is peeled off can be adjusted, and the peeled covering part W2 of the covering line W can be guided in a certain direction.

[0158] In addition, such as Figures 4 to 7 As shown, in a side view of the peeling tool 10, the blade 30 is mounted on the side of the detachment prevention portion 41b of the blade guide 41 near the covering line retainer 20. Therefore, when the covering portion W2 of the covering line W is peeled off using the blade 30, the blade 30 can engage with the covering line W before the blade guide 41.

[0159] (g) Press the shaft support table

[0160] The press shaft support 70 supports the press shaft 61, enabling it to move up and down. The press shaft support 70 is supported between the first side wall 56 and the second side wall 57. The press shaft support 70 is formed as a cuboid with sides along the left-right, up-down, and front-back directions. Figure 2 , Figure 5 , Figure 7 As shown, a press shaft threaded hole 70f, extending vertically, is formed at the center of the press shaft support 70 in both the front-rear and left-right directions. A threaded groove is formed on the inner surface of the press shaft threaded hole 70f. The press shaft 61 is inserted into the press shaft threaded hole 70f, allowing it to move vertically. As the engaging part 62 rotates, the threaded portion of the press shaft 61 is screwed into the threaded groove of the press shaft threaded hole 70f, and the press shaft 61 moves freely forward and backward along the vertical direction extending from the press shaft threaded hole 70f. Consequently, the blade holder 40, mounted on the front end of the press shaft 61, moves vertically.

[0161] In the press shaft support 70, a pair of guide shaft insertion holes 70g are formed rearward of the press shaft screw hole 70f, penetrating the press shaft support 70 in the vertical direction. The pair of guide shaft insertion holes 70g are symmetrically positioned in the left-right direction, centered on the press shaft screw hole 70f. Figure 5 and Figure 7As shown, the lower ends of a pair of guide shafts 63 are movably inserted into a pair of guide shaft insertion holes 70g in the vertical direction. When the pressing shaft 61 moves freely in the vertical direction along the pressing shaft screw hole 70f as the engaging part 62 rotates, the pair of guide shafts 63 move freely in the vertical direction extending from the pair of guide shaft insertion holes 70g. Specifically, since the upper ends of the pair of guide shafts 63 are pivotally connected to a pair of guide shaft pivot holes 40k of the blade holder 40, the pair of guide shafts 63 also move in the vertical direction as the pressing shaft 61 moves the blade holder 40. At this time, the lower ends of the pair of guide shafts 63 move along the pair of guide shaft insertion holes 70g. Thus, the pair of guide shafts 63 move in a state where wobbling in the left-right direction is suppressed, and the pressing shaft 61 also moves in a state where wobbling in the left-right direction is suppressed.

[0162] 2. Operating procedures for peeling tools

[0163] In order to peel off the covering portion W2 of the covering thread W of the desired diameter, the operator positions the desired covering thread holding portion 21 in the covering thread holding body 20 of the peeling tool 10 against the cutting edge 30. Therefore, the operator rotates the covering thread holding body 20 so that the desired covering thread holding portion 21 is aligned with the cutting edge 30.

[0164] First, the operator rotates the ring portion 62a of the engaging portion 62 to move the blade holder 40 downward in a manner that separates it from the wrapping wire holder 20. At this point, the operator moves the blade holder 40 downward to a point where the wrapping wire holder 20 and the blade holder 40 are no longer in contact.

[0165] Next, as Figure 8 As shown in (b), the holding part 53a of the fixing knob 53 is pulled away from the first sidewall 56, causing the front end 53c1 of the knob shaft 53c to disengage from the retaining body hole 25 (one of the first to fourth retaining body holes 25a to 25d) (fixed release state). In this fixed release state, the operator rotates the adjustment dial 51a of the rotation support part 51 so that one of the desired first to fourth wrapping line retaining parts 21a to 21d in the wrapping line retaining part 21 is opposite to the blade body 30. During the rotation of the adjustment dial 51a, the ball 54a of the positioning member 54 disengages from the positioning member sidewall hole 57h (one of the first to fourth sidewall holes 57h1 to 57h4) and slides on the inner wall surface of the second sidewall 57.

[0166] After the adjustment dial 51a has finished rotating, the operator returns the holding portion 53a of the fixing knob 53 to the direction close to the first sidewall 56, so that the front end 53c1 of the knob shaft 53c is inserted into the desired retaining hole 25 among the first to fourth retaining holes 25a to 25d. At this time, the ball 54a of the positioning member 54 is embedded in the desired positioning member sidewall hole 57h among the desired first to fourth sidewall holes 57h1 to 57h4 (fixed state). For example, if the desired wrapping thread retaining portion 21 is the second wrapping thread retaining portion 21b, the front end 53c1 of the fixing knob 53 is inserted into the second retaining hole 25b, and the ball 54a of the positioning member 54 is embedded in the second sidewall hole 57h2. Thus, the wrapping thread retaining body 20 is fixed in the predetermined position and rotation is prevented by the fixing member 52, the first sidewall 56, and the second sidewall 57.

[0167] Furthermore, the operator rotates the ring portion 62a while the desired coating line W is held between the coating line holding portion 21 and the blade body 30, causing the blade body holder 40 to move upwards towards the coating line holder 20. In this case, the operator moves the blade body holder 40 upwards so that the desired surface 22 of the first to fourth surfaces 22a to 22d of the coating line holder 20 contacts the upper surface of the blade body holder 40. For example, if the desired coating line holding portion 21 is the second coating line holding portion 21b, the second surface 22b of the coating line holder 20 contacts the upper surface of the blade body holder 40. Thus, the blade body 30 is engaged with the coating portion W2 of the coating line W.

[0168] As described above, after the peeling tool 10 is set, with the blade 30 engaged in the covering portion W2, the operator uses the ring portion 62a, etc. Figure 12 The peeling tool 10 is rotated with the covering line W as the center. Thus, as shown... Figure 11 As shown, the blade 30 circles around the covering line W, thereby peeling off the covering portion W2 of the covering line W.

[0169] According to the stripping tool 10 described above, a coating wire holder 20 has multiple coating wire holding portions 21 corresponding to multiple coating wires W with different diameters. Therefore, by preparing only one stripping tool 10 with one coating wire holder 20, it is possible to strip the coating portions W2 of multiple coating wires W with different diameters using this stripping tool 10. In other words, the hassle of using multiple stripping tools 10 separately for each of the multiple coating wires W with different diameters can be eliminated.

[0170] Furthermore, even when the liner holder 20 is supported by the support body 50, meaning even if the liner holder 20 is not separated from the support body 50, the relative relationship between one of the multiple liner holder portions 21 and the cutting edge 30 can be easily switched. Therefore, in a stripping tool 10 having one liner holder 20, it is easy to set it to strip the liner portions W2 of multiple liner Ws with different diameters.

[0171] Furthermore, according to the peeling tool 10 described above, the plurality of liner holding portions 21 are respectively arranged radially in the liner holding body 20 with the rotation axis 28 as the center. Therefore, by rotating the liner holding body 20 with the rotation axis 28 as the center, the relative relationship between one of the plurality of liner holding portions 21 and the blade body 30 can be easily switched.

[0172] Furthermore, according to the peeling tool 10 described above, by cutting off the corners of the rectangular shell in side view, four first to fourth liner holding portions 21a to 21d with approximately semi-circular cross-sections can be easily formed in four radial directions around the rotation axis 28. Moreover, since the first to fourth liner holding portions 21a to 21d are located at the corners of the block-shaped liner holding body 20, the first to fourth liner holding portions 21a to 21d can be switched sequentially by rotating the liner holding body 20 approximately 90° around the rotation axis 28.

[0173] Furthermore, according to the peeling tool 10 described above, when the fixing member 52 is in the unfixed state, by rotating the wrapping wire holder 20 around the rotating support, the relative relationship between one of the multiple wrapping wire holders 21 and the blade 30 can be switched. On the other hand, when the fixing member 52 is in the fixed state, the wrapping wire holder 20 is fixed to the side wall 55 by the fixing member 52, and the rotation of the wrapping wire holder 20 is prevented. Therefore, when peeling the wrapping part W2 by clamping the wrapping wire W between the wrapping wire holder 20 and the blade 30, the wobbling of the wrapping wire holder 20 can be prevented, so the wrapping part W2 can be cut to the desired size while preventing the blade 30 from contacting the core wire W1.

[0174] As described above, the embodiments of the present invention have been disclosed in the above description, but the present invention is not limited thereto.

[0175] That is, various changes can be made to the above-described embodiments, regarding the mechanism, shape, material, quantity, position or configuration, without departing from the technical concept and purpose of this utility model, and all such changes are included in this utility model.

[0176] (A)

[0177] Figure 1 In the peeling tool shown, the pressing shaft is screwed in freely relative to the pressing shaft support, but it is not limited to this. As long as the pressing shaft can move freely relative to the pressing shaft support, it can be set relative to the main body of the peeling tool in any way. For example, the pressing shaft is configured to slide freely relative to the pressing shaft support and can be fixed in any position.

[0178] (B)

[0179] in addition, Figure 1 The peeling tool shown includes a fixing component that prevents the rotation of the coating wire holder. However, the fixing component can be omitted as long as the rotation of the coating wire holder is prevented. If the fixing component is omitted, rotation of the coating wire holder can be prevented, for example, by having one of the first to fourth surfaces of the coating wire holder contact the upper surface of the blade holder and fixing the blade holder.

[0180] (C)

[0181] in addition, Figure 1 In the peeling tool shown, the sidewall connecting component is disposed on the back side of the wrapping wire holder, but it is not limited to this and the sidewall connecting component may not be disposed.

[0182] (D)

[0183] in addition, Figure 1 In the peeling tool shown, the suture holding parts in the suture holding body are arranged radially around the rotation axis, and the suture holding body is supported to be rotatable. Furthermore, by rotating the suture holding body, one of the multiple suture holding parts faces the cutting edge. However, the configuration of one of the multiple suture holding parts facing the cutting edge is not limited to this type of suture holding body.

[0184] For example, the crease retainer may have multiple crease retaining portions arranged in a front-to-back direction. Furthermore, the blade retainer is configured to move in the front-to-back direction. In this case, by keeping the crease retainer fixed and moving the blade retainer back and forth, one of the multiple crease retaining portions can be positioned opposite the blade. Conversely, the crease retaining portions may also be configured to move in the front-to-back direction. That is, by keeping the blade retainer fixed and moving the crease retainer back and forth, one of the multiple crease retaining portions can be positioned opposite the blade.

[0185] (E)

[0186] exist Figure 1In the peeling tool shown, the operator manipulates the lower ring or similar part of the peeling tool by hand while the blade is engaged in the covering part, causing the peeling tool to circle around the covering line and peel off the covering part using the blade. In other words, the peeling tool is used when the covering line is close to the operator's hand. However, it can also be used when the covering line is positioned far away from the operator.

[0187] (E-1)

[0188] In order to peel off the covering line that is positioned far from the operator, such as Figure 13 As shown, the peeling tool has a wrist body. Figure 13 This is a right view of a dissection tool with a wrist.

[0189] The wrist body 80 can be positioned at any location centered on the rotating support portion 51. The wrist body 80 extends radially in a circle centered on the rotating support portion 51 and is connected to, for example, the side wall 55 and the side wall connecting member 58. The wrist body 80 includes a wrist portion 80a and a wrist engaging portion 80b. One end of the wrist portion 80a is connected to the side wall 55 and the side wall connecting member 58, and the other end of the wrist portion 80a is connected to the wrist engaging portion 80b. The wrist portion 80a protrudes from one end toward the rear side opposite to the front side of the blade body 30 and the wrapping line holding portion 21 of the wrapping line holding body 20, and is positioned approximately perpendicular to the direction in which it extends relative to the pressing shaft 61.

[0190] The wrist-locking portion 80b includes a ring portion 80b1 and a base portion 80b2. The ring portion 80b1 is formed in a ring shape. The base portion 80b2 is engaged with the wrist portion 80a and the ring portion 80b1 is fixed thereon.

[0191] Next, the operating steps of the peeling tool 10 formed by the above will be explained.

[0192] The steps for aligning the desired coating thread holding portion 21 of the coating thread holder 20 with the blade body 30 are as described in the above embodiment. After aligning the coating thread holding portion 21 with the blade body 30, a space is ensured between the coating thread holding portion 21 and the blade body 30 so that the coating thread W can be inserted. With the peeling tool 10 suspended by the operator holding the wrist portion 80a using a clamp (not shown), a portion of the coating thread W is clamped between the coating thread holding portion 21, the blade body 30, and the blade body holder 40 from the rear side of the coating thread W, and the peeling tool 10 is mounted on the coating thread W.

[0193] Next, with the surface of the coating wire W facing the desired coating wire holding part 21, the front engagement part S2 of the insulating rod S1 of the operating tool S engages with the ring part 62a of the engagement part 62. Then, by rotating the insulating rod S1, the pressing shaft 61 is rotated, causing the blade 30 fixed to the blade holder 40 to bite into the coating wire W.

[0194] Next, the front engagement part S2 of the operating tool S is engaged with the ring part 62a, and the ring part 62a is rotated in a lifting manner. Then, the front engagement part S2 of the operating tool S is removed from the ring part 62a and re-engaged with the ring part 81b1 of the wrist engagement part 80b, and the ring part 81b1 is rotated in a lifting manner. That is, after rotating the peeling tool 10 360 degrees around the covering line W by engaging the front engagement part S2 with the ring parts 62a and 81b1, the peeling tool 10... Figure 11 The process results in the entire W2 covering being peeled off.

[0195] By rotating the engaging part 62 while the front end of the operating tool S is engaged with the ring part 62a, the pressing shaft 61 is rotated, causing the blade holder 40 to move away from the wrapping line W. Then, the peeling tool 10 is removed from the wrapping line W.

[0196] (E-2)

[0197] Unlike the above, using Figure 1 The peeling tool shown can also peel off the covering line that is positioned far away from the operator. That is, by simply engaging the front end S2 of the operating tool S with the ring 62a, and rotating the peeling tool 10 360 degrees around the covering line W, the covering part W2 can be peeled off completely.

[0198] (F)

[0199] exist Figure 1 In the peeling tool shown, the foremost point of the first cutting edge 31b is along the left-right direction. However, the foremost point of the first cutting edge 31b can also be diagonally crossed relative to the left-right direction.

[0200] Industrial availability

[0201] The peeling tool involved in this utility model can be suitably used, for example, to peel the covering portion W2 from the covering line covered by the covering portion W2.
