[0017] 1. Composition of the peeling tool The stripping tool 10 according to the present invention is a tool for stripping the coating W2 of a coated wire W. As shown in FIG. 11, the coated wire W includes a core wire W1 formed of a conductive material, and the coating W2 is provided so as to cover the core wire W1. The material of the coating W2 is usually a synthetic resin such as polyvinyl chloride or polyethylene, or a synthetic rubber. The stripping tool 10 according to the present invention is used, for example, by rotating the engagement portion 62 of the stripping tool 10 shown in FIG. 1, so that the blade tip portion 30b of the blade 30 of the stripping tool 10 bites into the coating W2, thereby stripping the coating W2 while leaving the core wire W1 without damaging it.

[0018] As shown in Figures 1 to 3, etc., the stripping tool 10 of the present invention mainly comprises a coated wire holder 20, a blade body 30 that cuts the coating portion W2 of the coated wire W, a blade body holder 40 that holds the blade body 30, and a support 50 that supports the coated wire holder 20 and the blade body holder 40.

[0019] The coated wire holder 20 is integrally formed with a plurality of coated wire holding portions 21 each capable of holding a corresponding one of a plurality of coated wires W having a plurality of different diameters. The blade 30 is held by the blade holder 40 and cuts the coating W2 of the coated wire W held by one of the plurality of coated wire holders 21. The support body 50 supports the covered wire holder 20 and the blade holder 40 in a state in which each of the multiple covered wire holding portions 21 and the blade body 30 face each other. With the covered wire holding body 20 supported by the support body 50, the facing relationship between any one of the plurality of covered wire holding parts 21 and the blade body 30 can be switched.

[0020] The stripping tool 10 includes the above-mentioned coated wire holder 20, blade body 30, blade body holder 40, and support 50, as well as a pair of blade guides 41 attached to the blade body holder 40. The stripping tool 10 further includes a pressing section 60 and a pressing shaft support base 70 that move the blade body holder 40 toward and away from the coated wire W.

[0021] In the present invention, the following definitions are used. In the stripping tool 10 in the posture shown in Figs. 1 to 3, etc., the side of the covered wire holder 20 relative to the blade holder 40 is referred to as the "upper side (top)" and the side of the blade holder 40 relative to the covered wire holder 20 is referred to as the "lower side (bottom)". In this specification, the front side shown in Fig. 2 is referred to as the "front, front side or near side" and the back side shown in Fig. 3 is referred to as the "rear or rear side". In Fig. 2, the right side is referred to as the "right side" and the left side is referred to as the "left side". When the covered wire W is gripped by the covered wire holder 20, the direction in which the covered wire W extends is the left-right direction.

[0022] In the stripping tool 10, the coated wire holder 20 and the blade holder 40 that holds the blade 30 are supported on both the left and right sides by the support 50 while facing each other in the vertical direction. The pressing section 60 is located below the blade holder 40 and is supported by a pressing shaft support base 70 so as to be movable back and forth in the vertical direction. The pressing shaft support base 70 is supported by the support base 50 below the blade holder 40.

[0023] In this embodiment, the covered wire holder 20, the blade holder 40, the support 50, the pressing portion 60 and the pressing shaft support base 70 are connected as follows. The support 50 includes a rotation support part 51, a fixed member 52, a first side wall 56 on the right side, and a second side wall 57 on the left side, which will be described later. The covered wire holder 20 and the pressing shaft support base 70 are supported in a state in which both left and right end faces of the covered wire holder 20 and both left and right end faces of the pressing shaft support base 70 are sandwiched between the first side wall 56 on the right side and the second side wall 57 on the left side. The covered wire holder 20 is supported by the rotation support part 51 at a position corresponding to the center of the covered wire holder 20 in a side view on the first side wall 56 and the second side wall 57 so as to be rotatable about the center as a rotation axis. The fixed member 52 is configured so that its tip can be inserted into the covered wire holder 20 from the outer surface side of the first side wall 56 at a position eccentric from the center of the covered wire holder 20 in a side view. When the tip of the fixed member 52 is inserted into the covered wire holder 20, the covered wire holder 20 becomes non-rotatable, and when the tip of the fixed member 52 is pulled out from the covered wire holder 20, the covered wire holder 20 becomes rotatable. The pressing portion 60 is supported by a pressing shaft support base 70 between the opposing surfaces of the first side wall 56 and the second side wall 57. The blade body holder 40 is supported above the pressing portion 60 by the pressing portion 60 between the opposing surfaces of the first side wall 56 and the second side wall 57. The blade body 30 is held by the blade body holder 40 so as to be able to peel off the coating W2 of the coated wire W.

[0024] The blade body holder 40 is moved up and down in accordance with the up and down movement of the pressing part 60. The pressing part 60 is moved downward away from the covered wire holder 20, widening the gap between the covered wire holder 20 and the blade body holder 40. With the gap widened, the covered wire W is placed between the covered wire holder 20 and the blade body holder 40, and the pressing part 60 is moved upward toward the covered wire holder 20. As a result, the covered wire W is sandwiched between the covered wire holder 20 and the blade body holder 40. The pressing part 60 is further moved toward the covered wire holder 20, causing the blade body 30 to bite into the covering part W2. Each part of the stripping tool 10 will be described below.

In addition, the side wall upper portion 56b of the first side wall 56 is formed with a plurality of arc-shaped weight reduction holes 56k penetrating in the plate thickness direction along the semicircular arc portion of the side wall upper portion 56b.

[0033] The sidewall fixing portion 56c of the first sidewall 56 is a portion that connects the first sidewall 56 and the second sidewall 57 to each other by a sidewall connecting member 58 (FIGS. 1, 3, and 8(a)) described later. The sidewall fixing portion 56c of the first sidewall 56 is formed so as to protrude rearward with respect to the central portion in the up-down direction of the sidewall upper 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 and the connecting member hole 58a1 (FIG. 8(a)) of the sidewall connecting member 58 are aligned with each other, and the sidewall fixing member 58b is fitted into them, thereby connecting the sidewall fixing member 58b to the first sidewall 56.

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 opposing surface of the sidewall fixing portion 56c of the first sidewall 56, and the left end face of the sidewall connecting member 58 contacts the opposing surface of the sidewall fixing portion 57c of the second sidewall 57, and the sidewall fixing holes 56i and 57i are aligned with the connecting member hole 58a1 of the sidewall connecting member 58 (FIG. 8(a)). In this state, sidewall fixing member 58b is fitted into sidewall fixing hole 56i of first sidewall 56, sidewall fixing hole 57i of second sidewall 57, and connecting member hole 58a1 of sidewall connecting member 58, thereby connecting first sidewall 56 and second sidewall 57 via sidewall fixing member 58b.

[0042] (a-2) Rotation support part The rotation support part 51 is a member for rotating the covered wire holder 20 around itself. The rotation support part 51 is disposed on the first side wall 56 so as to correspond to the center of the covered wire holder 20 in a side view. As shown in Fig. 8(a), the rotation support part 51 includes an adjustment dial 51a, a dial shaft 51b, a dial connecting member 51c, a dial shaft mounting member 51d, and a washer 51e.

[0043] The dial shaft 51b is formed in a cylindrical shape. The dial shaft 51b is inserted in the left-right direction through a dial side wall hole 56f of the first side wall 56, a dial shaft insertion hole 24 of the covered wire holder 20 described later, and the other end side wall hole 57f of the second side wall 57 so as to be rotatable around the axis (rotation axis 28 (FIG. 9A)). The dial shaft 51b is formed with a connecting hole 51b1 (FIG. 8(a)) that penetrates in a direction perpendicular to the axis direction. The dial connecting member 51c is inserted into the connecting hole 51b1. The dial connecting member 51c is longer than the length of 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 a connecting member engagement hole 26 of the covered wire holder 20 described later. As a result, the dial shaft 51b and the covered wire holder 20 are integrally connected.

[0044] A cylindrical adjustment dial 51a that rotates integrally with the dial shaft 51b is attached to one end of the dial shaft 51b in the axial direction. When the adjustment dial 51a rotates, the dial shaft 51b also rotates. The rotation of the dial shaft 51b makes it possible to easily rotate the covered wire holder 20. Therefore, the facing relationship between any of the multiple covered wire holders 21 described below and the blade body 30 can be easily switched. As shown in FIG. 8(a), one end of the dial shaft 51b penetrates the fixed knob side wall hole 56h, and the adjustment dial 51a that is continuous with one end of the dial shaft 51b protrudes outward from the first side wall 56 as shown in FIGS. 1 to 4 and FIG. 8(a). Since the diameter of the adjustment dial 51a is larger than the diameter of the dial shaft 51b, one end of the dial shaft 51b is engaged with the first side wall 56 by the adjustment dial 51a.

[0045] The adjustment dial 51a of the present embodiment is preferably provided with an index on its surface to enable visual confirmation of the covered wire holding portion 21 corresponding to the type of covered wire W of the covered wire holding body 20. The index is preferably provided with a numerical value or the like corresponding to the diameter or nominal cross-sectional area of ​​the covered wire W. In this case, the operator can adjust the covered wire holding body 20 to a predetermined position by rotating the adjustment dial 51a while referring to the index on the adjustment dial 51a.

[0046] A dial shaft mounting hole 51b2 is formed at the other end of the dial shaft 51b in the axial direction. As shown in Fig. 8(a), the other end of the dial shaft 51b penetrates the other end side wall hole 57f of the second side wall 57, and the dial shaft mounting member 51d is attached to the dial shaft mounting hole 51b2 with a washer 51e attached to the other end from the outer surface of the second side wall 57, so that the other end of the dial shaft 51b is engaged with the second side wall 57.

[0047] (a-3) Fixing member The fixing member 52 is a member that prevents rotation of the covered wire holder 20. Specifically, the fixing member 52 is a member that can switch between a fixed state in which the covered wire holder 20 is fixed to the pair of side walls 55 and a release state in which the fixed state of the covered wire holder 20 to the pair of side walls 55 is released. In the fixed state, the covered wire holder 20 is supported by the pair of side walls 55 so as not to rotate. In the release state, the covered wire holder 20 is supported by the pair of side walls 55 so as to be rotatable.

[0048] 8(a), the fixing member 52 includes a fixing knob 53 and a positioning member 54. In the present embodiment, the fixing member 52 is disposed to the side of the rotation support part 51 at a position eccentric from the center of the first side wall 56 (at a position eccentric from the center of the covered wire holder 20 in a side view) as shown in FIG.

[0049] The fixed knob 53 is an operating part that fixes the covered wire holder 20 at a predetermined rotational position. The fixed knob 53 includes a gripping part 53a, a knob base part 53b, a knob shaft 53c, a base 53d, and a base receiving part 53e. The fixed knob 53 is attached so as to protrude outward from the first side wall 56 with the base receiving part 53e fitted into the fixed knob side wall hole 56h.

[0050] The grip portion 53a is a circular member. The knob shaft 53c extends from the center of the grip portion 53a in a direction (left-right direction) perpendicular to the radial direction of the grip portion 53a. The knob shaft 53c has a tip 53c1 at its tip, which is inserted into a holder hole 25 (described later) of the covered wire holder 20 and pulled out from the holder hole 25. The knob base 53b is integrally connected to the grip portion 53a and the knob shaft 53c and supports them. The knob base 53b has a cylindrical shape, and is connected to the grip portion 53a while surrounding the knob shaft 53c at a portion of the knob shaft 53c adjacent to the grip portion 53a. The diameter of the knob base 53b is formed smaller than the diameter of the grip portion 53a so that the operator can easily grip the grip portion 53a.

[0051] The base 53d is a portion on which the knob base 53b is engaged and placed. The base 53d has a cylindrical shape and has a sliding contact portion with which the inner wall of the knob base 53b slides, and a step portion that continues to the sliding contact portion in a direction away from the knob base 53b. As shown in FIG. 8(b), when the grip portion 53a is moved in the left-right direction, the knob base 53b slides in the left-right direction along the sliding contact portion of the base 53d. When the grip portion 53a is moved most toward the first side wall 56, the knob base 53b abuts on the step portion of the base 53d and is stably supported. A knob insertion hole 53d1 through which the knob shaft 53c can be inserted is formed in the center of the base 53d.

[0052] The base receiving portion 53e is a portion to which the base 53d is integrally attached, and has a cylindrical shape. A base receiving hole 53e1 is formed in the center of the base receiving portion 53e. The base receiving portion 53e is attached to the fixed knob side wall hole 56h of the first side wall 56. The base 53d is fixed to the base receiving portion 53e so that the knob insertion hole 53d1 and the base receiving hole 53e1 communicate with each other.

[0053] The grip portion 53a and knob base 53b are configured to be able to come into contact with and separate from the pedestal 53d and the pedestal receiving portion 53e. When the knob base 53b comes into contact with the pedestal 53d as shown in Fig. 8(a), the tip 53c1 of the knob shaft 53c is inserted into the holder hole 25. On the other hand, when the knob base 53b is separated from the pedestal 53d as shown in Fig. 8(b), the tip 53c1 of the knob shaft 53c is pulled out of the holder hole 25.

[0054] The positioning member 54 is a member for fixing the covered wire holder 20 at a predetermined rotational position integrally with the fixing knob 53. The positioning member 54 includes a ball 54a, a spring 54b, and a receiving portion 54c.

[0055] The receiving portion 54c provides a receiving space for receiving the ball 54a and the spring 54b. The receiving portion 54c is fitted into a positioning member fitting hole 27 of the covered wire holder 20, which will be described later, so that the receiving space opens toward the second side wall 57. One end of the spring 54b is attached to the bottom of the receiving portion 54c, and the spring 54b has a biasing force from the bottom toward the second side wall 57. The ball 54a is attached to the other end of the spring 54b. The position of the ball 54a changes relative to the second side wall 57 as the covered wire holder 20 rotates relative to the side wall 55. Specifically, when the ball 54a is located in the positioning member side wall hole 57h of the second side wall 57, a part of the ball 54a fits into the positioning member side wall hole 57h due to the biasing force of the spring 54b. In this case, the positioning member 54, together with the fixing member 52, fixes the covered wire holder 20 in a predetermined position. On the other hand, when the ball 54a is not positioned in the positioning member side wall hole 57h, the ball 54a is in contact with the inner wall of the second side wall 57 and is accommodated in the accommodation portion 54c in a state in which the spring 54b is pressed by the pressure from the second side wall 57. In this case, the ball 54a is able to slide on the inner wall of the second side wall 57, and the covered wire holder 20 is able to rotate.

[0056] (b) Covered wire holder The covered wire holder 20 holds the covered wire W together with the blade body 30. The covered wire holder 20 is supported by a rotation support part 51 between a first side wall 56 and a second side wall 57. Fig. 9A (a) is a left side view of the covered wire holder, and Fig. 9A (b) to (e) are front views of the first to fourth faces of the covered wire holder. Fig. 9B (a) to (d) are schematic diagrams showing the relationship between each covered wire holder, the blade body, and the covered wire.

[0057] The covered wire holder 20 has a plurality of covered wire holding parts 21 formed integrally. Each of the plurality of covered wire holding parts 21 can hold a plurality of covered wires W having various diameters together with the blade body 30 and the blade body holder 40. When the covered wire holder 20 is supported by the support 50, the facing relationship between any of the plurality of covered wire holding parts 21 and the blade body 30 can be switched. In this embodiment, the covered wire holder 20 is configured to be rotatable about a rotation axis 28 in a side view, and the facing relationship between any of the plurality of covered wire holding parts 21 and the blade body 30 can be switched by the rotation of the covered wire holder 20. For this reason, the covered wire holder 20 is supported by the rotation support part 51 so as to be rotatable about the rotation axis 28. The covered wire holder 20 will be further described below.

[0058] As shown in Fig. 9A and Fig. 9B, the covered wire holder 20 of this embodiment is formed in a block shape. The covered wire holder 20 is formed with a dial shaft insertion hole 24 that is circular in side view. The dial shaft insertion hole 24 is formed so as to penetrate the center of the covered wire holder 20 in the left-right direction from the left side surface (Fig. 9A (a)) to the right side surface (Fig. 9B). As shown in Fig. 8 (a), the dial shaft 51b of the rotation support part 51 is inserted into the dial shaft insertion hole 24. Therefore, the dial shaft 51b is inserted into the dial side wall hole 56f of the first side wall 56, the dial shaft insertion hole 24, and the other end side wall hole 57f of the second side wall 57. In this state, the rotation support part 51 is engaged with the outer surface of the first side wall 56 by the adjustment dial 51a (Figures 4 and 8(a)), and is engaged with the outer surface of the second side wall 57 by the washer 51e and the dial shaft mounting member 51d (Figures 6 and 8(a)).

[0059] Furthermore, as shown in FIG. 9A(d), a groove-shaped connecting member engagement hole 26 is formed on the right side surface of the covered wire holder 20, extending in a direction perpendicular to the rotation shaft 28 with the dial shaft insertion hole 24 as the center. The connecting member engagement hole 26 is formed of two long holes extending in a direction perpendicular to the rotation shaft 28 from the dial shaft insertion hole 24. The two long holes are symmetrical with the dial shaft insertion hole 24 as the center. As shown in FIG. 8A(a), the dial connecting member 51c inserted into the connecting hole 51b1 of the dial shaft 51b is fitted into the connecting member engagement hole 26. That is, the rotation support part 51 and the covered wire holder 20 are connected to each other so as to be rotatable together via the dial connecting member 51c. In other words, the covered wire holder 20 rotates around the rotation shaft 28 together with the rotation of the rotation support part 51 caused by the rotation of the adjustment dial 51a.

[0060] The covered wire holding body 20 has a plurality of covered wire holding parts 21, and the facing relationship between any of the plurality of covered wire holding parts 21 and the blade body 30 can be switched by rotation about a rotation axis 28. The plurality of covered wire holding parts 21 are formed to hold covered wires W of different diameters.

[0061] In this embodiment, as an example of the covered wire holding portion 21, one covered wire holding body 20 has four covered wire holding portions 21 as shown in Figs. 9A and 9B. The four covered wire holding portions 21 are first, second, third and fourth covered wire holding portions 21a, 21b, 21c and 21d, respectively. The first to fourth covered wire holding portions 21a to 21d are each formed in a substantially semicircular shape with a different diameter in cross section. The cross sections are cross sections along the front-rear direction and the up-down direction. In this embodiment, the first to fourth covered wire holding portions 21a to 21d are formed in a semicircular shape with a diameter increasing in order. The first to fourth covered wire holding portions 21a to 21d extend along the left-right direction, that is, along the longitudinal direction of the covered wire W.

[0062] These inner surfaces of the substantially semicircular cross section face radially outward relative to the rotating shaft 28. In addition, these inner surfaces of the substantially semicircular cross section have a shape that is recessed when viewed from the radially outward so as to follow the outer peripheral surface of the covered wire W, and face the blade body 30. Each of the first to fourth covered wire holding parts 21a to 21d is formed by cutting out the corners of a rectangular parallelepiped housing whose sides run along the left-right, up-down, and front-rear directions in a side view. The right end face and the left end face of the covered wire holding body 20 run along the front-rear and up-down directions, and face the opposing surfaces of the first side wall 56 and the second side wall 57, respectively. The first to fourth covered wire holding parts 21a to 21d are located in four radial directions in the covered wire holding body 20 with the rotating shaft 28 of the covered wire holding body 20 as the center. Therefore, the opposing relationship between the blade body 30 and each of the first to fourth covered wire holding portions 21a to 21d can be changed every time the adjustment dial 51a is rotated by 90°. In this embodiment, the extending direction of the rotation shaft 28 of the covered wire holding body 20 and the extending direction of the tip end of the first blade tip portion 31b of the blade body 30 are the same left-right direction and are parallel to each other.

[0063] The first to fourth covered wire holding parts 21a to 21d will be further described. As shown in (a) to (d) of Fig. 9B, the first to fourth covered wire holding parts 21a to 21d are configured to hold covered wires W of different diameters together with the blade body 30 so that the blade body 30 can peel the covering parts W2 (W2a, W2b, W2c, W2d) of the covered wires W (Wa, Wb, Wc, Wd) of different diameters from the core wire W1 (W1a, W1b, W1c, W1d). That is, in (a) of Fig. 9B, the first covered wire holding part 21a is configured to hold the covered wire Wa together with the blade body 30 so that the blade body 30 can peel the covering part W2a of the covered wire Wa from the core wire W1a. In Fig. 9B(b), the second covered wire holding portion 21b is configured to hold the covered wire Wb together with the blade body 30 so that the blade body 30 can peel the covering portion W2b of the covered wire Wb from the core wire W1b. In Fig. 9B(c), the third covered wire holding portion 21c is configured to hold the covered wire Wc together with the blade body 30 so that the blade body 30 can peel the covering portion W2c of the covered wire Wc from the core wire W1c. In Fig. 9B(d), the fourth covered wire holding portion 21d is configured to hold the covered wire Wd together with the blade body 30 so that the blade body 30 can peel the covering portion W2d of the covered wire Wd from the core wire W1d.

[0064] 9B(a)-(d), each of the coated wire holding parts 21a-21d is configured to cover and contact at least a part of the surface of each of the plurality of coated wires W (Wa-Wd) having different diameters on a side different from the side where the blade body 30 contacts the coated wires W (Wa-Wd). The first to fourth coated wire holding parts 21a-21d are positioned radially in the radial direction of the coated wire holding body 20 centered on the rotation shaft 28, and are formed in a semicircular arc shape recessed toward the blade body 30. As a result, each of the coated wire holding parts 21a-21d covers and contacts at least a part of the surface of the coating portion W2 of the coated wire W before it is stripped by the blade body 30 while the stripping tool 10 is rotated and the blade body 30 strips the coating portion W2 of each coated wire W.

[0065] The positions of the covered wire holding portions 21a-21d on the covered wire holding body 20 are set in consideration of the length and direction of protrusion of the blade body 30 toward each of the covered wire holding portions 21a-21d, the diameter of the covered wire W, the thickness of the covering portion W2 of the covered wire W, and the like, so that the covering portion W2 can be peeled off by the blade body 30. The positions of the covered wire holding portions 21a-21d on the covered wire holding body 20 will be described in further detail below.

[0066] 9B(a), the first covered-wire holding portion 21a is formed to be able to hold the covered wire Wa between the apex, which is the tip of the blade body 30, and the first covered-wire holding portion 21a. The apex of the blade body 30 is positioned to be in contact with the surface of the core wire W1a so that the blade body 30 can peel the covering portion W2a from the core wire W1a. In this embodiment, the center W0a of the covered wire Wa is the center of the arc of the first covered-wire holding portion 21a, and the extending direction of the center W0a and the extending direction of the tip end of the first blade tip portion 31b of the blade body 30 are the same left-right direction and are parallel to each other.

[0067] In FIG. 9B (b), the second covered wire holding portion 21b is formed so as to be able to hold the covered wire Wb between the apex, which is the tip of the blade body 30, and the second covered wire holding portion 21b. The apex of the blade body 30 is located so as to be in contact with the surface of the core wire W1b so that the blade body 30 can peel the covering portion W2b from the core wire W1b. The direction in which the center W0b of the second covered wire holding portion 21b extends and the direction in which the tip of the first blade tip portion 31b of the blade body 30 extends are the same left-right direction and are parallel. In FIG. 9B (c), the third covered wire holding portion 21c is formed so as to be able to hold the covered wire Wc between the apex, which is the tip of the blade body 30, and the third covered wire holding portion 21c. The apex of the blade body 30 is located so as to be in contact with the surface of the core wire W1c so that the blade body 30 can peel the covering portion W2c from the core wire W1c. The direction in which the center W0c of the third covered wire holding portion 21c extends and the direction in which the tip of the first blade tip portion 31b of the blade body 30 extends are the same left-right direction and are parallel to each other. In FIG. 9B (d), the fourth covered wire holding portion 21d is formed so as to be able to hold the covered wire Wd between the apex, which is the tip of the blade body 30, and the fourth covered wire holding portion 21d. The apex of the blade body 30 is positioned so as to be in contact with the surface of the core wire W1d so that the blade body 30 can peel the covering portion W2d from the core wire W1d. The direction in which the center W0d of the fourth covered wire holding portion 21d extends and the direction in which the tip of the first blade tip portion 31b of the blade body 30 extends are the same left-right direction and are parallel to each other.

[0068] As shown in Figs. 4 to 7, the first and second side walls 56, 57 are configured so as not to interfere with the holding of the covered wire W by the first to fourth covered wire holding parts 21a to 21d and the blade body 30. Specifically, the covered wire holding opening 56e and the covered wire holding opening 57e of the first and second side walls 56, 57 have a diameter equal to or larger than that of the covered wire holding part 21, which has the largest diameter among the first to fourth covered wire holding parts 21a to 21d. Furthermore, when the covered wire holding body 20 is attached to the first and second side walls 56, 57, the opening edge parts of the covered wire holding opening 56e and the covered wire holding opening 57e are set back toward the rotation support part 51 from the edge parts of the first to fourth covered wire holding parts 21a to 21d.

[0069] The first to fourth covered wire 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 planar surfaces of the block-shaped covered wire holding body 20 that are not cut out other than the first to fourth covered wire holding portions 21a to 21d.

[0070] The fourth covered wire holding portion 21d and the first covered wire holding portion 21a are connected by a first surface 22a. When the first covered wire holding portion 21a and the blade body 30 face each other, the first surface 22a is along the horizontal direction and faces and contacts the upper surface of the blade body holder 40. The first covered wire holding portion 21a and the second covered wire holding portion 21b are connected by a second surface 22b. When the second covered wire holding portion 21b and the blade body 30 face each other, the second surface 22b is along the horizontal direction and faces and contacts the upper surface of the blade body holder 40. The second covered wire holding portion 21b and the third covered wire holding portion 21c are connected by a third surface 22c. When the third covered wire holding portion 21c and the blade body 30 face each other, the third surface 22c is along the horizontal direction and faces and contacts the upper surface of the blade body holder 40. The third covered wire holding portion 21c and the fourth covered wire holding portion 21d are connected by a fourth surface 22d. When the fourth covered wire holding portion 21d and the blade body 30 face each other, the fourth surface 22d is aligned in the horizontal direction and faces and contacts the upper surface of the blade body holder 40.

[0071] The rotation and prevention of rotation of the covered wire holder 20 can be set by the fixing member 52. As shown in FIG. 5, a plurality of first, second, third and fourth holder holes 25a, 25b, 25c and 25d are formed on the right side surface of the covered wire holder 20 in correspondence with the fixing knob 53 of the fixing member 52. The first to fourth holder holes 25a to 25d are formed in positions close to the first to fourth surfaces 22a to 22d, respectively. As shown in FIG. 4, the first side wall 56 is formed with a fixing knob side wall hole 56h corresponding to any one of the first to fourth holder holes 25a to 25d. In other words, the first side wall 56 is formed with a fixing knob side wall hole 56h (FIG. 4) to which the fixing knob 53 is engaged, and the fixing knob side wall hole 56h corresponds to any one of the first to fourth holder holes 25a to 25d.

[0072] 7 and 9A(a), a positioning member fitting hole 27 is formed on the left side surface of the covered wire holder 20 in correspondence with the positioning member 54 of the fixing member 52. In the example of FIG. 9A(a), the positioning member fitting hole 27 is formed at a position corresponding to the second surface 22b. Also, as shown in FIG. 6, first to fourth side wall holes 57h1 to 57h4 are formed in the second side wall 57 in correspondence with the positioning member fitting hole 27.

[0073] The rotation of the covered wire holder 20 is enabled by rotating the adjustment dial 51a with the gripping portion 53a of the fixed knob 53 positioned away from the first side wall 56 (FIG. 8(b)). In this case, the tip portion 53c1 of the knob shaft 53c is pulled out of all of the first to fourth holder holes 25a to 25d (holder holes 25). The ball 54a of the positioning member 54 is configured to slide on the inner wall surface of the second side wall 57 by pulling out of all of the first to fourth side wall holes 57h1 to 57h4 (positioning member side wall holes 57h).

[0074] On the other hand, the rotation of the covered wire holder 20 can be prevented by positioning the gripping portion 53a of the fixed knob 53 in a direction approaching the first side wall 56. In this case, the tip 53c1 of the knob shaft 53c is inserted into the holder hole 25 (one of the first to fourth holder holes 25a to 25d), so that the rotation of the covered wire holder 20 is prevented (fixed state). In the example of Figs. 4 to 7, the rotation of the covered wire holder 20 is prevented with the third covered wire holder 21c facing the blade body 30. In this case, the tip 53c1 of the fixed knob 53 is inserted into the second holder hole 25b of the covered wire holder 20. On the other hand, the ball 54a of the positioning member 54 is fitted into the second side wall hole 57h2 of the second side wall 57.

[0075] The first to fourth surfaces 22a to 22d are formed with holder openings 23 (first, second, third and fourth holder openings 23a, 23b, 23c and 23d). The first to fourth holder openings 23a to 23d are recesses that extend from the first to fourth surfaces 22a to 22d, respectively, to positions close to the dial shaft insertion hole 24. By forming the first to fourth holder openings 23a to 23d, the weight of the covered wire holder 20 can be reduced.

[0076] In the above, the covered wire holding body 20 is block-shaped, but the shape of the covered wire holding body 20 is not limited to this as long as the covered wire holding body 20 has a plurality of covered wire holding portions 21. The covered wire holding body 20 may be, for example, cylindrical or polygonal prism-shaped. Also, the covered wire holding body 20 may be formed by bending a plate-shaped member and performing sheet metal processing so as to have a plurality of covered wire holding portions 21 capable of holding the covered wire W. In the above, one covered wire holding body 20 has four covered wire holding portions 21, but the number of covered wire holding portions 21 is not limited to four, and may be two or more, or may be three or more. Also, the first to fourth surfaces 22a to 22d are not limited to being flat, and may be curved. Furthermore, the shape of each of the first to fourth covered wire holding parts 21a to 21d is not limited to a substantially semicircular cross section as long as it can hold the covered wire W. For example, the shape of the first to fourth covered wire holding parts 21a to 21d may be a substantially V-shaped cross section, a substantially triangular cross section, a substantially semi-elliptical cross section, or the like.

[0077] (c) Pressing part The pressing portion 60 vertically moves the blade holder 40. As shown in FIGS.

[0078] (c-1) Pressing shaft The pressing shaft 61 is supported on the underside of the blade holder 40 by a pressing shaft support base 70 between the opposing surfaces of the first side wall 56 and the second side wall 57. The pressing shaft 61 moves the blade holder 40 up and down in response to operation of the engagement portion 62.

[0079] As shown in Fig. 5 and Fig. 7, the pressing shaft 61 has a pressing shaft main body 61a, a connecting portion 61b, a first support portion 61c, a second support portion 61d, and a connecting portion 61e. The pressing shaft main body 61a is formed in a cylindrical shape extending in the vertical direction, and a threaded portion is formed on the outer surface. The pressing shaft main body 61a is inserted into the pressing shaft screw hole 70f of the pressing shaft support base 70 so as to be movable in the vertical direction. In other words, a screw groove is formed on the inner surface of the pressing shaft screw hole 70f, and the screw portion of the pressing shaft main body 61a and the screw groove of the pressing shaft screw hole 70f are screwed together, so that the pressing shaft main body 61a is movable in the vertical direction relative to the pressing shaft support base 70.

[0080] The connection part 61b is continuous with the lower side of the pressing shaft main body part 61a, and is a part that is connected to the engagement part 62. The connection part 61b is formed with a connection part engagement hole 61b1 (FIG. 7) that penetrates in a direction perpendicular to the extension direction of the pressing shaft main body part 61a.

[0081] 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 in a cylindrical shape with approximately the same diameter. The connecting portion 61e is formed in a cylindrical shape with a smaller diameter than 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.

[0082] (c-2) Engagement part The engaging portion 62 is a member for controlling 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 member connected to the pressing shaft 61 and is formed in a cylindrical shape extending in the vertical direction. The ring portion 62a is fixed to one side (the lower side in the case of FIG. 4) of the base portion 62b, and the other side (the upper side in the case of FIG. 4) is open. An engaging hole 62b2 is formed on the side surface of the base portion 62b. With the connecting portion 61b of the pressing shaft 61 inserted into the opening on the other side of the base portion 62b, a rod-shaped engaging member 62b1 is fitted into the engaging hole 62b2 of the base portion 62b and the connecting portion engaging hole 61b1 of the connecting portion 61b, and the engaging portion 62 and the connecting portion 61b of the pressing shaft 61 are engaged with each other. As a result, by rotating the engaging portion 62, the pressing shaft 61 can be rotated at the same time as the engaging portion 62 is rotated.

[0083] (c-3) Guide shaft The pair of guide shafts 63 guide the vertical movement of the pressing shaft 61. Each guide shaft 63 is formed in a cylindrical shape extending in the vertical direction. As shown in Figs. 5 and 7, the upper end of each guide shaft 63 is pivotally attached to the guide shaft pivot hole 40k of the blade body holder 40, and the lower end is inserted into the guide shaft insertion hole 70g of the pressing shaft support base 70 so as to be movable in the vertical direction. The pair of guide shafts 63 are arranged in the left-right direction with the pressing shaft 61 in between. The vertical movement of the pressing shaft 61 is guided by the pair of guide shafts 63, so that the rattling of the pressing shaft 61 in the lateral direction can be suppressed. Therefore, the blade body holder 40 can be stably moved in the vertical direction while suppressing the rattling of the blade body holder 40 in the lateral direction.

[0084] (d)Blade body The blade body 30 strips the coating W2 of the coated wire W.

[0085] As shown in Figs. 1, 2, and 4 to 7, the blade body 30 includes a first blade body 31, a pair of second blade bodies 32, and a blade body attachment member 33. The first blade body 31 bites into the coating portion W2 along the axial direction of the coated wire W and cuts the coating portion W2. The pair of second blade bodies 32 are disposed on both sides of the first blade body 31. The right second blade body 32 and the left second blade body 32 simultaneously bite into the coating portion W2 along the circumferential direction of the coated wire W and cut the coating portion W2.

[0086] The first blade body 31 is formed in a plate shape as a whole, and the plate surface is along the left-right direction and the up-down direction. Therefore, the plate surface of the first blade body 31 is perpendicular to the opposing surface of the first side wall 56 and the opposing surface of the second side wall 57. The first blade body 31 includes a first blade body main body 31a and a first blade body tip portion 31b. The first blade body main body 31a is continuous with the lower side of the first blade body tip portion 31b and supports the first blade body tip portion 31b. The first blade body main body 31a is a rectangular parallelepiped with each side along the left-right direction, the up-down direction, and the front-back direction, has a predetermined width in the left-right direction, and extends in the up-down direction. The first blade body main body 31a is formed with a first mounting hole 34 penetrating from the front side to the back side. The blade body mounting member 33 is inserted into the first mounting hole 34.

[0087] The first blade tip 31b is continuous with the upper side of the first blade body 31a, and is a portion that mainly peels off the coating W2 of the coated wire W along the axial direction. The width of the first blade tip 31b in the front-rear direction (thickness direction) decreases toward the upper side in the vertical direction, that is, toward the coated wire W held by the coated wire holding part 21. That is, the first blade tip 31b is formed in a tapered shape in which the length from the front side to the back side of the first blade tip 31b becomes shorter toward the tip (upper) side. In addition, the tip of the first blade tip 31b is along the left-right direction. With such a shape, the first blade tip 31b can bite into the coated wire W along the axial direction of the coated wire W and peel off the coating W2 of the coated wire W. In addition, the left-right length of the first blade tip 31b is approximately the same as the left-right length of the first blade body 31a. Furthermore, the left-right length of the first blade body portion 31a and the first blade tip portion 31b is approximately the same as the left-right length of the blade holder body portion 40b of the blade holder 40.

[0088] Each of the pair of second blade bodies 32 includes a second blade body main body portion 32a and a second blade body tip portion 32b. Each of the pair of second blade bodies 32 is a plate-shaped member. A through hole (not shown) into which a pair of guide mounting members 41d are screwed is formed so as to penetrate in a direction perpendicular to the plate-shaped surface of each of the pair of second blade bodies 32. By screwing the guide mounting member 41d into this through hole, each of the pair of second blade bodies 32 is disposed between the first blade body 31 and each of the pair of blade guides 41. Specifically, the right second blade body 32 of the pair of second blade bodies 32 is disposed so that the left plate-shaped surface of the second blade body 32 contacts the right end surface of the first blade body 31 and the right plate-shaped surface of the second blade body 32 contacts the opposing surface of the right blade guide 41 of the pair of blade guides 41. On the other hand, the left second blade body 32 of the pair of second blade bodies 32 is positioned so that the right plate surface of the second blade body 32 contacts the left end surface of the first blade body 31, and the left plate surface of the second blade body 32 contacts the opposing surface of the left blade guide 41 of the pair of blade guides 41.

[0089] The second blade body 32a is connected to the lower side of the second blade tip 32b and supports the second blade tip 32b. The second blade body 32a is formed to bulge forward from the first blade body 31a. The second blade tip 32b is connected to the upper side of the second blade body 32a and is a portion that mainly peels off the coating W2 of the coated wire W along the circumferential direction. The second blade tip 32b has a bulge more than the first blade tip 31b in the portion connected to the second blade body 32a, but the tip of the first blade tip 31b and the tip of the second blade tip 32b are aligned. In other words, the vertical position of the tip of the first blade tip 31b and the vertical position of the tip of the second blade tip 32b are aligned.

[0090] The blade body 30 and the blade body holder 40 are separate and independent, and the blade body 30 is configured to be connected to the blade body holder 40, so that the blade body 30 is replaceable with respect to the blade body holder 40.

[0091] (e) Blade holder The blade body holder 40 holds the blade body 30. Specifically, the blade body holder 40 holds the blade body 30 such that the covered wire W is held between the blade body 30 and the covered wire holding portion 21 of the covered wire holder 20. The blade body holder 40 is supported by a pressing shaft 61 between the opposing surface of the first side wall 56 and the opposing surface of the second side wall 57, and is movable up and down by the up and down movement of the pressing shaft 61. Fig. 10(a) is a side view of the blade body holder, and Fig. 10(b) is a bottom view of the blade body holder.

[0092] The blade holder 40 includes a blade holder base 40a, a blade holder main body 40b, and a holder tip 40c. The blade holder base 40a is located behind the blade holder main body 40b, and is formed in a rectangular parallelepiped shape with each side aligned in the left-right, up-down, and front-rear directions. The left-right length of the blade holder base 40a is approximately the same as the left-right width of the covered wire holder 20. The blade holder base 40a is formed with a pair of guide shaft pivot holes 40k that extend from the bottom surface in the up-down direction and are concave with closed tops. The pair of guide shaft pivot holes 40k are symmetrically arranged with respect to the left-right center of the blade holder base 40a. The tip ends of a pair of guide shafts 63 are pivotally attached to the pair of guide shaft pivot holes 40k, respectively. As a result, the blade holder 40 and the pair of guide shafts 63 move together in the up-down direction.

[0093] The blade holder main body 40b is continuous with the front side of the blade holder base 40a, and is formed in a rectangular parallelepiped shape with each side extending in the left-right, up-down, and front-rear directions. Furthermore, the holder tip 40c is continuous with the front lower end of the blade holder main body 40b, and is formed in a substantially rectangular parallelepiped shape with each side extending in the left-right, up-down, and front-rear directions. The upper surface of the blade holder main body 40b and the upper surface of the blade holder base 40a are substantially flush with each other. The upper surface of the holder tip 40c is located lower than the upper surface of the blade holder main body 40b, and a step is formed between the blade holder main body 40b and the holder tip 40c. In this step, the blade holder main body 40b has a blade mounting surface 40d, which is the front surface of the blade holder main body 40b. Furthermore, in the step portion, the holder tip portion 40c has a blade mounting surface 40e which is the upper surface of the holder tip portion 40c.

[0094] Here, a pair of second mounting holes 40f facing the blade mounting surface 40d are formed in the blade holder main body 40b. As shown in Fig. 5 and Fig. 7, the blade 30 is attached to the blade holder 40 by fitting the blade mounting member 30c from the first mounting hole 30d to the second mounting hole 40f with the back surface of the blade 30 in contact with the blade mounting surface 40d and the lower surface of the blade 30 in contact with the blade mounting surface 40e. The vertical length of the blade mounting surface 40d is the length at which the blade tip 30b at least protrudes from the upper surface of the blade holder main body 40b. The front-rear length of the blade mounting surface 40e is approximately the same as the front-rear length of the blade 30.

[0095] The left-right length of the blade body holder base 40a is longer than the left-right length of the blade body holder main body 40b. In a front view, the left-right center of the blade body holder base 40a and the left-right center of the blade body holder main body 40b are approximately aligned. Therefore, in a front view of the blade body holder 40, both left-right ends of the blade body holder base 40a protrude in the left-right direction beyond both left-right ends of the blade body holder main body 40b.

[0096] A pair of guide mounting holes 40g are formed on both left and right side surfaces of the blade body holder main body 40b. The pair of guide mounting holes 40g are formed toward the front side of the blade body holder main body 40b. A pair of guide mounting members 41d for mounting the second blade 32 and a blade guide 41 (described later) to the blade body holder main body 40b are screwed into the pair of guide mounting holes 40g, respectively.

[0097] As shown in Fig. 10(b), a cylindrical pressing shaft tip hole 40h is formed in the blade body holder main body 40b facing the lower surface. The pressing shaft tip hole 40h is a recess having a predetermined depth from the lower surface of the blade body holder main body 40b. The pressing shaft tip hole 40h is formed in the center of the blade body holder main body 40b in the left-right direction and behind the pair of guide attachment holes 40g.

[0098] Furthermore, the blade holder main body 40b is further formed with a pair of anti-slip member insertion holes 40i facing both left and right side surfaces. The pair of anti-slip member insertion holes 40i are formed to extend symmetrically in the left and right direction with the pressing shaft tip hole 40h as the center while communicating with the pressing shaft tip hole 40h. Specifically, the pair of anti-slip member insertion holes 40i communicate with the pressing shaft tip hole 40h at the center in the front-rear direction of the pressing shaft tip hole 40h as shown in Fig. 10(b) and at the center in the up-down direction of the pressing shaft tip hole 40h as shown in Figs. 5 and 7.

[0099] As shown in Fig. 5 and Fig. 7, the tip of the pressing shaft 61 is inserted into the pressing shaft tip hole 40h. Then, a slip-prevention member 40j is inserted from at least one of the pair of slip-prevention member insertion holes 40i toward the pressing shaft tip hole 40h. The tip of the slip-prevention 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 slip-prevention member 40j is supported so as to be sandwiched between the first support portion 61c and the second support portion 61d. As a result, the pressing shaft 61 is rotatably engaged with the blade holder 40.

[0100] In addition, for example, when the covered wire holder 20 and the blade body 30 are in a state where they can hold the covered wire W, such as during peeling, the blade body holder 40 and the covered wire holder 20 are in surface contact. Specifically, the upper surface of the blade body holder 40 is flat and formed along the horizontal direction. When a desired covered wire holder 21 among the first to fourth covered wire holders 21a to 21d is set to face the blade body 30, any of the first to fourth surfaces 22a to 22d and the upper surface of the blade body holder 40 are in surface contact. Since the blade body holder 40 and the covered wire holder 20 are in surface contact in this manner, the positional relationship between the blade body holder 40 and the covered wire holder 20 can be fixed more stably than when they are in point contact. Therefore, by preventing the covered wire holder 20 from wobbling when the covered wire W is sandwiched between the covered wire holder 20 and the blade body 30 and the covering portion W2 is peeled off, the covered wire W can be held in a stable state between the covered wire holder 21 and the blade body 30. Furthermore, the positional relationship between the blade body holder 40 and the covered wire holder 20 can be adjusted by rotating the pressing shaft 61 and adjusting the amount of movement until the blade body holder 40 comes into surface contact with the covered wire holder 20. In other words, the positional relationship between the blade body holder 40 and each of the first to fourth covered wire holding portions 21a to 21d of the covered wire holder 20 is adjusted by the amount of movement, so that the distance that the blade body 30 bites into the covered wire W can be adjusted.

[0101] (f) Blade guide 1 and 4 to 7, a pair of blade guides 41 are attached to the left and right sides of the blade body 30 and the blade body holder 40. Specifically, the pair of blade guides 41 are attached so as to cover the left and right outer sides of the pair of second blade bodies 32.

[0102] The pair of blade guides 41 determine the position where the coating portion W2 of the coated wire W is stripped, guide the stripped coating portion W2 to be output in a certain direction, and prevent the stripped coating portion W2 from falling. The pair of blade guides 41 are plate-shaped members.

[0103] The blade guide 41 includes a guide body 41a and a fall prevention portion 41b. A through hole (not shown) is formed in the guide body 41a. As shown in FIG. 10(b) and FIGS. 4 to 7, with the second blade body 32 and the blade guide 41 disposed on the side surface of the blade body holder 40, a guide attachment member 41d is inserted into the through hole (not shown) of the second blade body 32 and the through hole of the blade guide 41. Furthermore, the guide attachment member 41d is screwed into the guide attachment hole 40g of the blade body holder 40, whereby the second blade body 32 and the blade guide 41 are attached to the blade body holder 40.

[0104] The fall-off prevention portion 41b extends forward of the guide body portion 41a and extends upward beyond the guide body portion 41a. By adjusting the dimension at which the fall-off prevention portion 41b protrudes forward and upward beyond the guide body portion 41a, the position at which the covering portion W2 of the covered wire W is stripped can be adjusted and the covering portion W2 of the stripped covered wire W can be guided to be output in a fixed direction.

[0105] 4 to 7, in a side view of the stripping tool 10, the blade body 30 is attached closer to the covered wire holder 20 than the fall-off prevention portion 41b of the blade guide 41. This allows the blade body 30 to bite into the covered wire W before the blade guide 41 when the covering portion W2 of the covered wire W is stripped by the blade body 30.

[0106] (g) Pressure shaft support stand The pressing shaft support base 70 supports the pressing shaft 61 so as to be movable up and down. The pressing shaft support base 70 is supported between the first side wall 56 and the second side wall 57. The pressing shaft support base 70 is formed in a rectangular parallelepiped shape with each side along the left-right direction, the up-down direction, and the front-rear direction. As shown in Figs. 2, 5, and 7, a pressing shaft screw hole 70f is formed in the front-rear direction center and the left-right direction center of the pressing shaft support base 70, penetrating in the up-down direction. A screw groove is formed on the inner surface of the pressing shaft screw hole 70f. The pressing shaft 61 is inserted into the pressing shaft screw hole 70f so as to be movable up and down. As the engaging portion 62 rotates, the screw portion of the pressing shaft 61 is screwed into the screw groove of the pressing shaft screw hole 70f, and the pressing shaft 61 is freely movable forward and backward along the up-down direction in which the pressing shaft screw hole 70f extends. As a result, the blade holder 40 attached to the tip of the pressing shaft 61 moves up and down.

[0107] A pair of guide shaft insertion holes 70g are formed in the pressing shaft support base 70 at the rear of the pressing shaft screw hole 70f, penetrating the pressing shaft support base 70 in the up-down direction. The pair of guide shaft insertion holes 70g are formed at positions symmetrical in the left-right direction with the pressing shaft screw hole 70f as the center. As shown in Figs. 5 and 7, the lower ends of the pair of guide shafts 63 are inserted into the pair of guide shaft insertion holes 70g so as to be movable in the up-down direction. When the pressing shaft 61 moves freely forward and backward along the up-down direction of the pressing shaft screw hole 70f with the rotation of the engagement portion 62, the pair of guide shafts 63 move freely forward and backward along the up-down direction in which the pair of guide shaft insertion holes 70g extend. Specifically, since the upper ends of the pair of guide shafts 63 are pivotally attached to the pair of guide shaft pivot holes 40k of the blade body holder 40, the pair of guide shafts 63 also move in the up-down direction as the pressing shaft 61 moves the blade body holder 40 in the up-down direction. At this time, the lower ends of the pair of guide shafts 63 move along the pair of guide shaft insertion holes 70g. As a result, the pair of guide shafts 63 are moved with their left-right deflection suppressed, and the pressing shaft 61 is also moved with their left-right deflection suppressed.

[0108] 2. Operating procedure for peeling tool In order to strip the coating portion W2 of a coated wire W having a desired diameter, the operator positions a desired coated wire holding portion 21 of the coated wire holding body 20 of the stripping tool 10 opposite the blade body 30. To this end, the operator rotates the coated wire holding body 20 to position the desired coated wire holding portion 21 opposite the blade body 30.

[0109] First, the operator rotates the ring portion 62a of the engagement portion 62 to move the blade body holder 40 downward so as to separate it from the covered wire holder 20. At this time, the operator moves the blade body holder 40 downward to an extent that the covered wire holder 20 and the blade body holder 40 do not come into contact with each other.

[0110] 8(b), the grip portion 53a of the fixed knob 53 is pulled in a direction away from the first side wall 56, and the tip portion 53c1 of the knob shaft 53c is pulled out of the holder hole 25 (any of the first to fourth holder holes 25a to 25d) (unfixed state). In this unfixed state, the operator rotates the adjustment dial 51a of the rotation support portion 51 so that a desired one of the first to fourth covered wire holding portions 21a to 21d of the covered wire holding portion 21 faces the blade body 30. In the process of rotating the adjustment dial 51a, the ball 54a of the positioning member 54 comes out of the positioning member side wall hole 57h (any of the first to fourth side wall holes 57h1 to 57h4) and slides on the inner wall surface of the second side wall 57.

[0111] When the rotation of the adjustment dial 51a is completed, the operator returns the gripping portion 53a of the fixed knob 53 in a direction approaching the first side wall 56, and inserts the tip portion 53c1 of the knob shaft 53c into a desired holder hole 25 among the first to fourth holder holes 25a to 25d. At this time, the ball 54a of the positioning member 54 is fitted into a desired positioning member side wall hole 57h among the desired first to fourth side wall holes 57h1 to 57h4 (fixed state). For example, when the desired covered wire holding portion 21 is the second covered wire holding portion 21b, the tip portion 53c1 of the fixed knob 53 is inserted into the second holder hole 25b, and the ball 54a of the positioning member 54 is fitted into the second side wall hole 57h2. As a result, the covered wire holding body 20 is fixed at a predetermined position by the fixing member 52, the first side wall 56, and the second side wall 57, and rotation is prevented.

[0112] Furthermore, with the covered wire W held between the desired covered wire holding portion 21 and the blade body 30, the operator rotates the ring portion 62a to move the blade body holder 40 upward so as to approach the covered wire holder 20. In this case, the operator moves the blade body holder 40 upward so that the desired surface 22 out of the first to fourth surfaces 22a to 22d of the covered wire holder 20 comes into surface contact with the upper surface of the blade body holder 40. For example, when the desired covered wire holding portion 21 is the second covered wire holding portion 21b, the second surface 22b of the covered wire holder 20 comes into contact with the upper surface of the blade body holder 40. This brings the blade body 30 into the covering portion W2 of the covered wire W.

[0113] After the setting of the stripping tool 10 is completed as described above, next, with the blade body 30 biting into the coating portion W2, the operator rotates the stripping tool 10 around the coated wire W using the ring portion 62a or the like as shown in Fig. 12. As a result, the blade body 30 rotates around the coated wire W, as shown in Fig. 11, so that the coating portion W2 of the coated wire W is stripped off.

[0114] According to the above-described stripping tool 10, one coated wire holder 20 has a plurality of coated wire holding portions 21 corresponding to a plurality of coated wires W having a plurality of different diameters. Therefore, by simply preparing one stripping tool 10 having one coated wire holder 20, the coating portions W2 of a plurality of coated wires W having different diameters can be stripped by the stripping tool 10. In other words, it is possible to reduce the effort of using a plurality of stripping tools 10 corresponding to a plurality of coated wires W having different diameters.

[0115] Furthermore, the opposing relationship between any one of the multiple covered wire holding parts 21 and the blade body 30 can be easily switched while the covered wire holding body 20 is supported by the support body 50, that is, even if the covered wire holding body 20 is not separated from the support body 50. Therefore, with one stripping tool 10 having one covered wire holding body 20, it is easy to set it up so that the coverings W2 of multiple covered wires W having different diameters can be stripped.

[0116] Furthermore, according to the above-mentioned stripping tool 10, each of the multiple coated wire holding portions 21 is arranged radially around the rotation axis 28 in the coated wire holding body 20, so that the opposing relationship between any of the multiple coated wire holding portions 21 and the blade body 30 can be easily switched by rotating the coated wire holding body 20 around the rotation axis 28.

[0117] Moreover, with the stripping tool 10, by cutting out the corners of the casing that is rectangular in side view, it is possible to easily form the first to fourth covered wire holding parts 21a to 21d that are substantially semicircular in cross section in four radial directions about the rotation shaft 28. Moreover, since the first to fourth covered wire holding parts 21a to 21d are located at the corners of the block-shaped covered wire holding body 20, respectively, the first to fourth covered wire holding parts 21a to 21d can be switched in order by rotating the covered wire holding body 20 about the rotation shaft 28 in increments of about 90°.

[0118] Furthermore, according to the stripping tool 10, when the fixing member 52 is in an unlocked state, the covered wire holding body 20 can be rotated about the rotation support portion to switch the opposing relationship between any of the multiple covered wire holding parts 21 and the blade body 30. On the other hand, when the fixing member 52 is in a fixed state, the covered wire holding body 20 is fixed to the side wall 55 by the fixing member 52, thereby preventing the covered wire holding body 20 from rotating. Therefore, when the covered wire W is sandwiched between the covered wire holding body 20 and the blade body 30 to strip the covering portion W2, the covered wire holding body 20 can be prevented from wobbling, and the covering portion W2 can be cut to a desired size while preventing the blade body 30 from coming into contact with the core wire W1.

[0119] As described above, the embodiment of the present invention has been disclosed in the above description, but the present invention is not limited thereto. In other words, various modifications can be made to the above-described embodiments in terms of mechanism, shape, material, quantity, position, arrangement, etc. without departing from the scope of the technical idea and purpose of the present invention, and these are included in the present invention.

[0120] (A) 1, the pressing shaft is screwed into the pressing shaft support base so as to be movable back and forth, but the present invention is not limited to this, and the pressing shaft may be provided in any manner on the peeling tool body as long as it is movable back and forth relative to the pressing shaft support base. For example, the pressing shaft is configured to slide back and forth relative to the pressing shaft support base and to be fixed at any position.

[0121] (B) 1 includes a fixing member that prevents the rotation of the coated wire holder. However, if the rotation of the coated wire holder is prevented, the fixing member can be omitted. When the fixing member is omitted, for example, the rotation of the coated wire holder can be prevented by making surface contact between any one of the first to fourth surfaces of the coated wire holder and the upper surface of the blade body holder and fixing the blade body holder.

[0122] (C) Furthermore, in the stripping tool shown in FIG. 1, the side wall connecting member is disposed on the back side of the covered wire holder, but this is not limited thereto, and the side wall connecting member does not necessarily have to be disposed.

[0123] (D) 1, the coated wire holding parts are arranged in radial positions around a rotation axis in the coated wire holding body, and the coated wire holding body is rotatably supported. When the coated wire holding body is rotated, one of the plurality of coated wire holding parts faces the blade body. However, the configuration in which one of the plurality of coated wire holding parts faces the blade body is not limited to this embodiment of the coated wire holding body.

[0124] For example, the covered wire holder may have a plurality of covered wire holding parts arranged in a line in the front-rear direction. The blade body holder is configured to be movable in the front-rear direction. In this case, the covered wire holder is left fixed, and the blade body holder is moved back and forth to make one of the plurality of covered wire holding parts face the blade. Conversely, the covered wire holding part may be configured to be movable in the front-rear direction. In other words, the blade body holder is left fixed, and the blade body is moved back and forth to make one of the plurality of covered wire holding parts face the blade.

[0125] (E) In the stripping tool shown in Fig. 1, an operator inserts the blade into the coating and rotates the stripping tool around the insulated wire by manually manipulating a ring or the like at the bottom of the stripping tool, thereby stripping the coating with the blade. In other words, the stripping tool is used when the insulated wire is located close to the operator's hand. However, the stripping tool may also be used when the insulated wire is located remotely from the operator.

[0126] (E-1) In order to strip a wire that is located remotely from an operator, the stripping tool has an arm as shown in Fig. 13. Fig. 13 is a right side view of the stripping tool having the arm.

[0127] The arm 80 can be provided at any position around the rotation support part 51. The arm 80 is connected to, for example, the side wall 55 and the side wall connecting member 58 so as to extend in the radial direction of a circle around the rotation support part 51. The arm 80 includes an arm 80a and an arm engaging part 80b. One end of the arm 80a is connected to the side wall 55 and the side wall connecting member 58, and the other end of the arm 80a is connected to the arm engaging part 80b. The arm 80a protrudes from one end to the other end on the rear side opposite to the front side where the blade body 30 and the covered wire holding part 21 of the covered wire holding body 20 face each other, and in a direction approximately perpendicular to the extension direction of the pressing shaft 61.

[0128] The arm engaging 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 coupled to the arm portion 80a and has the ring portion 80b1 fixed thereto.

[0129] Next, an operating procedure for the peeling tool 10 having the above configuration will be described.

[0130] The procedure for arranging the desired covered wire holding portion 21 of the covered wire holding body 20 and the blade body 30 to face each other is as described in the above embodiment. After the covered wire holding portion 21 and the blade body 30 are arranged to face each other, a space is secured between the covered wire holding portion 21 and the blade body 30 to allow the covered wire W to be inserted. The operator, while holding the arm portion 80a with a clamping tool (not shown) to suspend the stripping tool 10, attaches the stripping tool 10 to the covered wire W from the rear side of the covered wire W, which is located remotely, by clamping a part of the covered wire W between the covered wire holding portion 21 and the blade body 30 and the blade body holder 40.

[0131] Next, with the surface of the covered wire W aligned with the desired covered wire holding portion 21, the tip engaging portion S2 provided at the tip of the insulating rod S1 of the operating tool S is engaged with the ring portion 62a of the engaging portion 62. Next, the insulating rod S1 is rotated to rotate the pressing shaft 61, thereby causing the blade 30 fixed to the blade holder 40 to bite into the covered wire W.

[0132] Next, the tip engaging portion S2 of the operating tool S is hooked onto the ring portion 62a, and the ring portion 62a side is rotated so as to lift up. Next, the tip engaging portion S2 of the operating tool S is detached from the ring portion 62a, and re-hooked onto the ring portion 81b1 of the arm engaging portion 80b, and the ring portion 81b1 is rotated so as to lift up. In other words, by hooking the tip engaging portion S2 onto the ring portion 62a and the ring portion 81b1, the stripping tool 10 is rotated 360 degrees around the covered wire W, and the covering portion W2 is stripped off over the entire circumference through the process shown in FIG.

[0133] By rotating the engagement portion 62 with the tip engagement portion S2 of the operating tool S hooked on the ring portion 62a, the pressing shaft 61 is rotated about its axis, and the blade holder 40 is moved in a direction away from the coated wire W. Then, the stripping tool 10 is removed from the coated wire W.

[0134] (E-2) 1, it is also possible to strip a covered wire located remotely from the operator. That is, the tip engagement portion S2 of the operating tool S can be hooked only on the ring portion 62a, and the stripping tool 10 can be rotated 360 degrees around the covered wire W to strip the covering portion W2 from the entire circumference.

[0135] (F) 1, the tip of the first blade tip 31b is aligned along the left-right direction. However, the tip of the first blade tip 31b may be aligned diagonally relative to the left-right direction. [Industrial Applicability]

[0136] The stripping tool according to the present invention can be suitably used, for example, to strip the covering portion W2 from a covered wire covered with the covering portion W2. [Explanation of symbols]
