Each of the plurality of covered wire holding parts 21 can hold each of the plurality of covered wires W having various diameters together with the blade body 30 and the blade body holder 40. In a state where the covered wire holder 20 is supported by the support 50, the facing relationship between any one of the plurality of covered wire holders 21 and the blade body 30 is configured to be switchable. In this embodiment, the covered wire holder 20 is configured to be rotatable around a rotation axis 28 in a side view, and the rotation of the covered wire holder 20 causes the blade body 30 to connect with any one of the plurality of covered wire holders 21. The opposing relationship between the two is configured to be switchable. For this reason, the covered wire holder 20 is rotatably supported by the rotation support portion 51 around the rotation shaft 28 . The covered wire holder 20 will be further explained below.

As shown in FIGS. 9A and 9B, the covered wire holder 20 of this embodiment is formed in a block shape. A dial shaft insertion hole 24 having a circular shape in side view is formed in the covered wire holder 20 . The dial shaft insertion hole 24 is formed so as to pass through the center of the covered wire holder 20 in the left-right direction from the left side ((a) of FIG. 9A) to the right side (FIG. 9B). The dial shaft 51b of the rotation support portion 51 is inserted into the dial shaft insertion hole 24, as shown in FIG. 8(a). Therefore, the dial shaft 51b is inserted through 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.

The plurality of covered wire holding parts 21 are formed to hold covered wires W having different diameters.

In this embodiment, one covered wire holder 20 has four covered wire holders 21 as an example of the covered wire holders 21, as shown in FIGS. 9A and 9B. The four covered wire holding sections 21 are first, second, third and fourth covered

wire holding sections

21a, 21b, 21c and 21d, respectively. Each of the first to fourth covered wire holding parts 21a to 21d is formed to have a substantially semicircular cross section with a different diameter. The cross section is a cross section along the front-back direction and the up-down direction. In this embodiment, the first to fourth covered wire holding parts 21a to 21d are formed in a semicircular shape whose diameter increases in order. Further, the first to fourth covered wire holding parts 21a to 21d extend along the left-right direction, that is, along the longitudinal direction of the covered wire W.

These inner surfaces having a substantially semicircular cross section face outward in the radial direction with respect to the rotating shaft 28. Moreover, these inner surfaces having a substantially semicircular cross section are recessed when viewed from the outside in the radial direction so as to be along the outer circumferential surface of the covered wire W, and face the blade body 30. Each of the first to fourth coated wire holding parts 21a to 21d is formed by cutting out a corner of a rectangular parallelepiped-shaped housing, each side of which extends in the left-right direction, up-down direction, and front-back direction when viewed from the side. . The right end surface and the left end surface of the covered wire holder 20 are along the front-rear direction and the up-down direction, and face the opposing surface of the first side wall 56 and the opposing surface of the second side wall 57, respectively. The first to fourth covered wire holders 21a to 21d are located in four radial directions in the covered wire holder 20 with the rotation axis 28 of the covered wire holder 20 as the center. Therefore, each time the adjustment dial 51a is rotated by 90 degrees, the facing relationship between the blade body 30 and each of the first to fourth coated wire holding parts 21a to 21d can be changed. In this embodiment, the direction in which the rotating shaft 28 of the covered wire holder 20 extends and the direction in which the leading edge of the first blade tip 31b of the blade 30 extends are the same left-right direction and are parallel to each other. be.

Thereby, by rotating the engaging portion 62, the pressing shaft 61 can be rotated simultaneously with the rotation of the engaging portion 62.

(c-3) Guide shafts 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 connected to the guide shaft pivot hole 40k of the blade holder 40, and the lower end is vertically connected to the guide shaft insertion hole 70g of the pressing shaft support 70. It is inserted so that it can be moved in any direction. The pair of guide shafts 63 are arranged in the left-right direction with the pressing shaft 61 in between. Since the vertical movement of the pressing shaft 61 is guided by the pair of guide shafts 63, it is possible to suppress rattling of the pressing shaft 61 in the lateral direction. Therefore, the blade holder 40 can be stably moved in the vertical direction while suppressing horizontal wobbling of the blade holder 40.

(d) Blade The blade 30 peels off the covering portion W2 of the covered wire W.

The blade body 30 includes a first blade body 31, a pair of second blade bodies 32, and a blade attachment member 33, as shown in FIGS. 1, 2, and 4 to 7. The first blade 31 bites into the covered portion W2 along the axial direction of the covered wire W and cuts the covered portion W2. A pair of second blade bodies 32 are arranged on both sides of the first blade body 31. The second blade body 32 on the right side and the second blade body 32 on the left side simultaneously bite into the coated portion W2 along the circumferential direction of the coated wire W and cut the coated portion W2.

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

The first blade tip portion 31b is continuous to the upper side of the first blade body portion 31a, and is a portion that mainly peels off the covering portion W2 of the covered wire W along the axial direction. The width of the first blade tip 31b in the front-rear direction (thickness direction) decreases as it goes upward in the vertical direction, that is, as it goes toward the covered wire W held by the covered wire holding section 21. That is, the first blade tip 31b is formed in a tapered shape in which the length between the front side and the back side of the first blade tip 31b becomes shorter toward the tip (upper) side. Further, the leading edge of the first blade tip portion 31b is along the left-right direction. With such a shape, the first blade tip 31b can bite into the covered wire W along the axial direction of the covered wire W, and can peel off the covering portion W2 of the covered wire W. Further, the length of the first blade tip portion 31b in the left-right direction is approximately the same as the length of the first blade body portion 31a in the left-right direction. Furthermore, the length of the first blade main body portion 31a and the first blade tip portion 31b in the left-right direction is approximately the same as the length of the blade holder main body portion 40b of the blade holder 40 in the left-right direction.

Each of the pair of second blade bodies 32 includes a second blade main body portion 32a and a second blade tip portion 32b. Each of the pair of second blade bodies 32 is a plate-like member. Each of the pair of second blade bodies 32 is formed with a through hole (not shown) into which the pair of guide attachment members 41d is screwed, passing through the hole in a direction perpendicular to the plate-like surface. By screwing the guide attachment member 41d into this through hole, each of the pair of second blade bodies 32 is arranged between the first blade body 31 and each of the pair of blade guides 41. Specifically, of the pair of second blade bodies 32, the right second blade body 32 is such that the left plate-like surface of the second blade body 32 is in contact with the right end surface of the first blade body 31, and the second blade body 32 is The right plate-like surface of the blade body 32 is arranged so as to be in contact with the opposing surface of the right blade guide 41 of the pair of blade guides 41. On the other hand, of the pair of second blade bodies 32, the left second blade body 32 is such that the right plate-like surface of the second blade body 32 is in contact with the left end surface of the first blade body 31, and the second blade body 32 is The left plate-like surface of the blade guide 32 is arranged so as to be in contact with the opposing surface of the left blade guide 41 of the pair of blade guides 41.

The second blade main body portion 32a is continuous to the lower side of the second blade tip portion 32b, and supports the second blade tip portion 32b. The second blade main body portion 32a is formed to bulge more forward than the first blade main body portion 31a. The second blade tip portion 32b is continuous to the upper side of the second blade body portion 32a, and is a portion that mainly peels off the covering portion W2 of the covered wire W along the circumferential direction. The second blade tip 32b has a larger bulge than the first blade tip 31b in the part that is continuous with the second blade main body 32a. It coincides with the tip of the second blade tip 32b. That is, 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 match.

The blade 30 and the blade holder 40 are separate and independent, and the blade 30 is connected to the blade holder 40, so the blade 30 is replaceable with respect to the blade holder 40. be.

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

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 on the rear side of the blade holder main body 40b, and is formed into a rectangular parallelepiped shape with each side extending in the left-right direction, the up-down direction, and the front-back direction. The length of the blade holder base 40a in the left-right direction is approximately the same as the width of the covered wire holder 20 in the left-right direction. The blade holder base 40a is formed with a pair of concave guide shaft mounting holes 40k that extend vertically from the lower surface and are closed at the top. The pair of guide shaft pivot holes 40k are arranged symmetrically with respect to the center of the blade holder base 40a in the left-right direction. The distal end portions of the pair of guide shafts 63 are pivotally attached to each of the pair of guide shaft pivot holes 40k. As a result, the blade holder 40 and the pair of guide shafts 63 move together in the vertical direction.

The blade holder main body portion 40b is continuous with the front side of the blade holder base 40a, and is formed in the shape of a rectangular parallelepiped with each side extending in the left-right direction, the up-down direction, and the front-back direction. Further, the holder tip portion 40c is continuous with the lower front end of the blade holder main body portion 40b, and is formed into a substantially rectangular parallelepiped shape with each side extending in the left-right direction, the up-down direction, and the front-back direction. The upper surface of the blade holder body portion 40b and the upper surface of the blade holder base portion 40a are substantially flush with each other. The upper surface of the holder tip portion 40c is located below the upper surface of the blade holder main body portion 40b, and the blade holder main body portion 40b and the holder tip portion 40c form a stepped portion. In this stepped portion, the blade holder main body portion 40b has a blade mounting surface 40d, which is a front surface of the blade holder main body portion 40b. Further, in the stepped portion, the holder tip portion 40c has a blade mounting surface 40e, which is an upper surface of the holder tip portion 40c.

Here, a pair of second mounting holes 40f facing the blade mounting surface 40d are formed in the blade holder main body portion 40b. As shown in FIGS. 5 and 7, 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 first mounting hole 30d is The blade 30 is attached to the blade holder 40 by fitting the blade attachment member 30c into the second attachment hole 40f. The length of the blade attachment surface 40d in the vertical direction is such that the blade tip 30b protrudes from at least the upper surface of the blade holder main body 40b. Further, the length of the blade mounting surface 40e in the front-rear direction is approximately the same as the length of the blade 30 in the front-rear direction.

The length of the blade holder base 40a in the left-right direction is longer than the length of the blade holder main body 40b in the left-right direction. In a front view, the center of the blade holder base portion 40a in the left-right direction and the center of the blade holder main body portion 40b in the left-right direction substantially coincide with each other. Therefore, when the blade holder 40 is viewed from the front, both ends of the blade holder base 40a in the left and right direction protrude further in the left and right direction than both ends of the blade holder main body 40b.

A pair of guide attachment holes 40g are formed in the blade holder main body portion 40b, facing each of both side surfaces in the left and right direction. The pair of guide attachment holes 40g are formed closer to the front side of the blade holder main body portion 40b. A pair of guide attachment members 41d for attaching the second blade 32 and a blade guide 41 (described later) to the blade holder main body portion 40b are respectively screwed into the pair of guide attachment holes 40g.

As shown in FIG. 10(b), a cylindrical pressing shaft tip hole 40h facing the lower surface is formed in the blade holder main body portion 40b. The pressing shaft tip hole 40h is a recessed portion having a predetermined depth from the lower surface of the blade holder main body portion 40b. The pressing shaft tip hole 40h is formed in the center of the blade holder main body portion 40b in the left-right direction and on the rear side of the pair of guide attachment holes 40g.

Further, the blade holder main body portion 40b is further formed with a pair of slip-off prevention member insertion holes 40i facing each of both side surfaces in the left and right direction. The pair of slip-off prevention member insertion holes 40i are formed to extend symmetrically in the left-right direction centering around the press shaft tip hole 40h, while communicating with the press shaft tip hole 40h. Specifically, each of the pair of slip-off prevention member insertion holes 40i is located at the central portion of the pressing shaft tip hole 40h in the front-rear direction as shown in FIG. The center portion of the shaft tip hole 40h in the vertical direction communicates with the pressing shaft tip hole 40h.

As shown in FIGS. 5 and 7, the tip of the pressing shaft 61 is inserted into the pressing shaft tip hole 40h. A slip-off prevention member 40j is inserted from at least one of the pair of slip-off prevention member insertion holes 40i toward the pressing shaft tip hole 40h. The distal end portion of the slip-off prevention member 40j projects 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-off prevention member 40j is supported so as to be sandwiched between the first support portion 61c and the second support portion 61d. Thereby, the pressing shaft 61 is rotatably locked to the blade holder 40.

Further, in a state where the covered wire holder 20 and the blade 30 can hold the covered wire W, for example, during peeling, the blade holder 40 and the covered wire holder 20 are in surface contact. Specifically, the upper surface of the blade holder 40 is planar and is formed along the horizontal direction. When a desired covered wire holding section 21 among the first to fourth covered wire holding sections 21a to 21d is set to face the blade body 30, any one of the first to fourth surfaces 22a to 22d and the upper surface of the blade holder 40 are in surface contact. Since the blade holder 40 and the covered wire holder 20 are in surface contact in this way, the positional relationship between the blade holder 40 and the covered wire holder 20 is more stably fixed than in the case of point contact. can do. Therefore, by sandwiching the coated wire W between the coated wire holder 20 and the blade body 30 and preventing the coated wire holder 20 from wobbling when peeling the coated portion W2, the coated wire holder 21 and the blade body The coated wire W can be held in a stable state between the wire and the wire. Further, the positional relationship between the blade holder 40 and the covered wire holder 20 can be adjusted by rotating the pressing shaft 61 and changing the amount of movement until the blade holder 40 comes into surface contact with the covered wire holder 20. can. That is, since the positional relationship between the blade holder 40 and the first to fourth covered wire holders 21a to 21d of the covered wire holder 20 is adjusted by the amount of movement, the blade 30 bites into the covered wire W. The distance can be adjusted.

(f) Blade Guide As shown in FIGS. 1 and 4 to 7, a pair of blade guides 41 are attached to each of the left and right sides of the blade 30 and the blade holder 40. Specifically, a pair of blade guides 41 are attached so as to cover the right and left outer sides of the pair of second blade bodies 32.

The pair of blade guides 41 determine the peeling position of the coated portion W2 of the coated wire W, guide the peeled coated portion W2 to be output in a certain direction, and prevent the peeled coated portion W2 from falling. be. The pair of blade guides 41 are plate-like members.

The blade guide 41 includes a guide main body portion 41a and a fall prevention portion 41b. A through hole (not shown) is formed in the guide main body portion 41a. As shown in FIG. 10(b) and FIGS. 4 to 7, when the second blade 32 and the blade guide 41 are arranged on the side surface of the blade holder 40, the second blade 32 penetrates (not shown). A guide attachment member 41d is inserted into the hole and the through hole of the blade guide 41. Further, the second blade 32 and the blade guide 41 are attached to the blade holder 40 by screwing the guide attachment member 41d into the guide attachment hole 40g of the blade holder 40.

The falling-off prevention part 41b extends to the front side of the guide main body part 41a and to the upper side of the guide main body part 41a. By adjusting the dimension in which the fall-off prevention part 41b is provided so as to protrude forward and upward from the guide main body part 41a, it is possible to adjust the position at which the sheathing part W2 of the sheathed wire W is peeled off, and the position of the peeled sheathed wire W can be adjusted. It is possible to guide the covering portion W2 so as to output it in a certain direction.

Further, as shown in FIGS. 4 to 7, in a side view of the stripping tool 10, the blade body 30 is attached closer to the coated wire holder 20 than the falling-off prevention part 41b of the blade guide 41. Thereby, when peeling off the coated portion W2 of the coated wire W with the blade body 30, the blade body 30 can bite into the coated wire W before the blade guide 41 does.

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

A pair of guide shaft insertion holes 70g that vertically penetrate the press shaft support 70 are formed behind the press shaft screw hole 70f in the press shaft support 70. The pair of guide shaft insertion holes 70g are formed at symmetrical positions in the left-right direction with the press 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 respectively inserted into the pair of guide shaft insertion holes 70g so as to be movable in the vertical direction. When the pressing shaft 61 moves forward and backward along the vertical direction of the pressing shaft screw hole 70f as the engaging portion 62 rotates, the pair of guide shafts 63 move along the vertical direction in which the pair of guide shaft insertion holes 70g extend. Move freely forward and backward. Specifically, since the upper ends of the pair of guide shafts 63 are pivotally connected to the pair of guide shaft pivot holes 40k of the blade holder 40, it is difficult for the pressing shaft 61 to move the blade holder 40 in the vertical direction. Along with this, the pair of guide shafts 63 also move in the vertical 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 in the left-right direction with less wobbling, and the pressing shaft 61 is also moved in the left-right direction with less wobbling.

2. Operation procedure of the stripping tool In order to strip the coated portion W2 of the coated wire W of a desired diameter, the operator connects the desired coated wire holding portion 21 and the blade body 30 of the coated wire holder 20 of the stripping tool 10. to face each other. Therefore, the operator rotates the covered wire holder 20 so that the desired covered wire holder 21 and the blade 30 face each other.

First, the operator moves the blade holder 40 downward away from the coated wire holder 20 by rotating the ring part 62a of the engagement part 62. At this time, the operator moves the blade holder 40 downward to such an extent that the covered wire holder 20 and the blade holder 40 do not come into contact with each other.

Next, as shown in FIG. 8B, the grip portion 53a of the fixed knob 53 is pulled in the direction away from the first side wall 56, and the tip portion 53c1 of the knob shaft 53c is (fixed release state). In this fixed release state, the operator adjusts the adjustment dial of the rotation support part 51 so that any one of the desired first to fourth covered wire holding parts 21a to 21d of the covered wire holding parts 21 faces the blade body 30. Rotate 51a. 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. do.

When the rotation of the adjustment dial 51a is completed, the operator returns the grip 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 the first to fourth holder holes 25a to 25d. It is inserted into a desired holding body hole 25 among them. 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 section 21 is the second covered wire holding section 21b, the tip 53c1 of the fixed knob 53 is inserted into the second holding body hole 25b, and the ball 54a of the positioning member 54 is inserted into the second side wall hole. Fits in 57h2. As a result, the covered wire holder 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.

Furthermore, the operator rotates the ring portion 62a while holding the coated wire W between the desired coated wire holder 21 and the blade 30, thereby moving the blade holder 40 to the coated wire holder 20. Move it upwards so that it is closer to . In this case, the operator moves the blade holder 40 upward so that a desired surface 22 of the first to fourth surfaces 22a to 22d of the covered wire holder 20 and the upper surface of the blade holder 40 come into surface contact. Move to. For example, when the desired covered wire holder 21 is the second covered wire holder 21b, the second surface 22b of the covered wire holder 20 contacts the upper surface of the blade holder 40. As a result, the blade body 30 is in a state where it bites into the covered portion W2 of the covered wire W.

When 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 uses the ring portion 62a etc. to remove the coating wire W as shown in FIG. The peeling tool 10 is rotated around the center. As a result, as shown in FIG. 11, the blade 30 rotates around the coated wire W, thereby peeling off the coated portion W2 of the coated wire W.

According to the above-mentioned stripping tool 10, one covered wire holder 20 has a plurality of covered wire holders 21 corresponding to each of a plurality of covered 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. That is, it is possible to reduce the effort of using a plurality of stripping tools 10 for each of the plurality of coated wires W having different diameters.

Further, even when the covered wire holder 20 is supported by the support 50, that is, even if the covered wire holder 20 is not separated from the support 50, any one of the plurality of covered wire holders 21 and the blade 30 can be connected to each other. The facing relationship can be easily switched. Therefore, in one stripping tool 10 having one coated wire holder 20, settings can be easily made such that the coated portions W2 of a plurality of coated wires W having different diameters can be stripped.

Moreover, according to the above-mentioned stripping tool 10, since each of the plurality of coated wire holding parts 21 is arranged in the radial direction centering on the rotating shaft 28 in the covered wire holding body 20, the coated wire holding body 20 is By rotating around 28, the opposing relationship between any one of the plurality of coated wire holding parts 21 and the blade body 30 can be easily switched.

Further, according to the above-described peeling tool 10, by cutting out the corners of the rectangular parallelepiped-shaped housing when viewed from the side, four first strips having a substantially semicircular cross section are formed in four radial directions about the rotating shaft 28. The fourth to fourth covered wire holding parts 21a to 21d can be easily formed. In addition, since the first to fourth covered wire holders 21a to 21d are respectively located at the corners of the block-shaped covered wire holder 20, the covered wire holder 20 is rotated approximately 90 degrees around the rotating shaft 28. By rotating it, the first to fourth covered wire holding parts 21a to 21d can be switched in order.

Moreover, according to the above-mentioned stripping tool 10, when the fixing member 52 is in the unfixed state, the coated wire holder 20 is rotated about the rotating support part, so that the blade can be attached to any one of the plurality of coated wire holders 21. The facing relationship with the body 30 can be switched. On the other hand, when the fixing member 52 is in the fixed state, the covered wire holder 20 is fixed to the side wall 55 by the fixing member 52, thereby preventing the covered wire holder 20 from rotating. Therefore, when the coated wire holder 20 is sandwiched between the coated wire holder 20 and the blade body 30 and the coated portion W2 is peeled off, wobbling of the coated wire holder 20 can be prevented. It is possible to cut the covering portion W2 to desired dimensions while preventing contact with the portion 30.

As mentioned above, although the embodiments of the present invention are disclosed in the above description, the present invention is not limited thereto.
That is, various changes can be made to the embodiment described above 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 are included in the present invention.

(A)
In the peeling tool shown in FIG. 1, the pressing shaft is screwed into the pressing shaft support base so as to be able to move forward and backward, but this is not restrictive. As long as it can move forward and backward, it may be provided in any way with respect to the peeling tool body. For example, the pressing shaft is configured to be able to slide forward and backward with respect to the pressing shaft support base and to be fixed at any position.

(B)
Further, the stripping tool shown in FIG. 1 includes a fixing member that prevents rotation of the coated wire holder. However, if the rotation of the covered wire holder is prevented, the fixing member can be omitted. When the fixing member is omitted, for example, one of the first to fourth surfaces of the covered wire holder and the upper surface of the blade holder are brought into surface contact and the blade holder is fixed, so that the covered wire holder is fixed. rotation can be prevented.

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

(D)
In addition, in the stripping tool shown in FIG. 1, the covered wire holding parts are arranged in radial positions about the rotating shaft in the covered wire holder, and the covered wire holder is rotatably supported. Then, as the covered wire holder is rotated, any one of the plurality of covered wire holders faces the blade. However, the configuration in which any one of the plurality of covered wire holders faces the blade is not limited to this embodiment of the covered wire holder.

For example, the covered wire holder may have a plurality of covered wire holders arranged in a line in the front-rear direction. The blade holder is configured to be movable in the front-rear direction. In this case, by leaving the covered wire holder fixed and moving the blade holder back and forth, the blade can be opposed to any one of the plurality of covered wire holders. Conversely, the covered wire holding section may be configured to be movable in the front-back direction. That is, by leaving the blade holder fixed and moving the covered wire holder back and forth, the blade can be opposed to any one of the plurality of covered wire holders.

(E)
In the stripping tool shown in Fig. 1, the operator manually manipulates the ring section at the bottom of the stripping tool with the blade biting into the coated portion, and moves the stripping tool around the coated wire. By rotating the blade, the coating is peeled off by the blade. In other words, the stripping tool is used with the coated wire close to the operator's hand. However, the stripping tool may be used with the covered wire located remotely from the operator.

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

The arm body 80 can be provided at any position centering on the rotation support part 51. The arm body 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 centered on the rotation support portion 51 . The arm body 80 includes an arm portion 80a and an arm engaging portion 80b. One end of the arm portion 80a is connected to the side wall 55, the side wall connecting member 58, etc., and the other end of the arm portion 80a is connected to an arm engaging portion 80b. The arm portion 80a is on the rear side opposite to the front side where the blade body 30 and the covered wire holding portion 21 of the covered wire holding body 20 face each other from one end to the other end, and the pressing shaft 61 extends. It protrudes in a direction substantially perpendicular to the direction.

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 the ring portion 80b1 is fixed thereto.

Next, the operating procedure of the peeling tool 10 having the above configuration will be explained.

Next, hook the tip engaging part S2 of the operating instrument S onto the ring part 62a, and turn it so as to lift the ring part 62a side. Next, the tip engaging part S2 of the operating instrument S is removed from the ring part 62a, hooked onto the ring part 81b1 of the arm engaging part 80b, and turned so as to lift the ring part 81b1. That is, when the stripping tool 10 is rotated 360 degrees around the coated wire W by hooking the distal end engaging portion S2 on the ring portion 62a and the ring portion 81b1, the coated portion W2 is rotated over the entire circumference through the process shown in FIG. It becomes stripped.

By rotating the engaging part 62 with the tip engaging part S2 of the operating instrument S hooked on the ring part 62a, the pressing shaft 61 is rotated, and the blade holder 40 is moved in the direction away from the covered wire W side. move it to Then, the stripping tool 10 is removed from the coated wire W.

(E-2)
Differently from the above, the stripping tool shown in FIG. 1 can also be used to strip a covered wire that is located remotely from the operator. That is, it is also possible to hook the distal end engaging portion S2 of the operating instrument S only on the ring portion 62a, rotate the stripping tool 10 360 degrees around the coated wire W, and strip the coated portion W2 over the entire circumference.

(F)
In the peeling tool shown in FIG. 1, the leading edge of the first blade tip 31b is along the left-right direction. However, the leading edge of the first blade tip 31b may intersect diagonally with respect to the left-right direction.

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.
