  A pair of holding means 22 and 22 are arrange | positioned at the both sides of the width direction so that the holder main body 21 may be pinched | interposed. Each holding means 22 includes a pair of clamping bodies 221 and 222 that clamp the wire X, and a position adjusting means 223 that adjusts the position between the clamping bodies 221 and 222.

  One clamping body (hereinafter also referred to as “first clamping body”) 221 is sandwiched between the other clamping body (hereinafter also referred to as “second clamping body”) 222 and sandwiches the wire X. Part (hereinafter, also referred to as “first clamping part”) 221a. The first pinching body 221 is configured to be relatively displaceable with respect to the holder main body 21.

  The first clamping portion 221a is formed in a concave shape so as to accommodate the wire X, and is formed in a line-symmetric taper shape so as to guide and position the wire X to be accommodated. Specifically, the first clamping unit 221a is formed in a groove shape that expands outward.

  The second clamping body 222 includes a clamping unit (hereinafter, also referred to as “second clamping unit”) 222a that clamps the wire X with the first clamping unit 221a. Further, the second pinching body 222 is fixed to the holder main body 21.

  The second clamping part 222a is formed in a convex shape having a smaller width dimension than the inner width dimension of the concave first clamping part 221a. And the 2nd clamping part 222a is arrange | positioned so that a front-end | tip part may be located between the cutting blades 111 and 111, and may be located in the base end side of the cutting blade 111. FIG.

  The position adjusting means 223 is provided on the inner periphery with a column member 223a having one end fixed to the first pinching body 221 and the other end inserted into an insertion hole 222b provided in the second pressing body 222 ( A female) screw is provided with an operation member 223b that is screwed with the (male) screw provided on the outer periphery of the support member 223a and is operated by an operator.

  Since the support member 223a is formed such that the insertion hole 222b of the second pinching body 222 expands toward one end, the column member 223a is relatively displaced with respect to the second pressing body 222 in a state of being inserted into the insertion hole 222b. it can. Specifically, the column member 223a can move so as to rotate around the other end side.

  As a result, the first pinching body 221 is more external than between the cutting blades 111 and 111 in order to prevent interference with the wire X when the wire X is inserted between the opened cutting blades 111 and 111. In order to prevent the wire X inserted between the cutting blades 111 and 111 from being placed in the standby position and the cutting blades 111 and 111, a partial position is disposed between the cutting blades 111 and 111. , 111 can be switched to a locking position at which the wire X inserted between them can be locked.

  Specifically, the first pinching body 221 is positioned away from between the cutting blades 111 and 111 in the axial direction of the wire X, that is, in the direction orthogonal to the plate-like blade member 11 (cutting blade 111). A certain standby position and a locking position that is a position in which the partial position is disposed between the cutting blades 111 and 111 and can surround the wire X by the partial position and the two cutting blades 111 and 111 in the same direction. I can move.

  Since the operating member 223b is formed larger than the insertion hole 222b of the second pinching body 222, the second pressing body 222 can be locked. And the operation member 223b can adjust the distance between both the clamping bodies 221 and 222, ie, the both clamping parts 221a and 222a, by screwing with the support | pillar member 223a.

  The configuration of the cutting tool according to the present embodiment is as described above. Next, a method for cutting the wire X with the cutting tool according to the present embodiment will be described.

  First, as illustrated in FIG. 6A, the wire X is inserted between the opened cutting blades 111 and 111. At this time, since the first pinching body 221 is located at a standby position that is outward (downward) than between the cutting blades 111 and 111 due to gravity, the first pinching body 221 extends along the center between the cutting blades 111 and 111 (FIG. 6). Even if the wire X is inserted (in the direction of arrow A in (a)), the first pinching body 221 does not interfere with the wire X.

  Then, the first pinching body 221 is rotated along the flat blade member 11 (in the direction of arrow B in FIG. 6A). Then, as shown in FIG. 6B, since the first pinching body 221 is located at a locking position where the wire X positioned on the proximal end side of each cutting blade 111 can be locked, the wire X is It is possible to prevent the blades 111 and 111 from slipping out.

  Thereafter, when the operation member 223b is rotated (in the direction of arrow C in FIG. 6B), the first pinching body 221 moves toward the second pinching body 222 (in the direction of arrow D in FIG. 6B). Moving. As a result, the distance between the two pressing members 221 and 222 that are separated with the wire X interposed therebetween, specifically, the distance between the both pressing portions 221a and 222a is gradually reduced.

  Further, when the operation member 223b is rotated and continuously tightened, the first pinching portion 221a formed in a concave shape and a taper shape guides the wire X. And finally, as shown to Fig.7 (a), the 1st clamping part 221a accommodates the wire X, and positions it in a predetermined position. At this time, the first clamping unit 221a and the second clamping unit 222a hold the wire X by clamping.

  Then, when each blade member 11 is rotated so that the cutting blades 111 and 111 are closed (in the direction of arrow E in FIG. 7A), as shown in FIG. The wire X inserted in can be cut. Thereafter, when the operation member 223b is rotated in the opposite direction (F direction in FIG. 7B) and loosened, the pinching of the wire X by the both pinching portions 221a and 222a can be released, and the wire (both cut wires). The piece X can be removed from the holding means 2 and 2 respectively.

  As described above, in the cutting tool according to the present embodiment, the pair of holding units 2 and 2 hold the portions on both sides in the portion of the wire X cut by the pair of cutting blades 111 and 111. Thereby, in a state where the pair of holding means 2 and 2 holds the wire X, the wire X inserted between the opened cutting blades 111 and 111 can be cut by closing the cutting blades 111 and 111. When cutting the wire X, the wire X can be safely cut by one person while holding the grips 121 and 121 with both hands.

  Further, in the cutting tool according to the present embodiment, the pair of pressing portions 221a and 222a press the wire X, so that each holding means 2 can hold the wire X. And since the 1st clamping part 221a is formed in concave shape, while being able to accommodate the wire X, since it forms in a taper shape, it can guide and position the wire X to accommodate. Therefore, it is possible to easily match the axis of the wire X with the centers of the two cutting blades 111 and 111.

  In addition, the cutting tool according to the present embodiment includes a wire X inserted between the cutting blades 111 and 111 in a standby position in which the first pinching body 221 is more outward than between the opened cutting blades 111 and 111. Can be switched to a lockable position.

  Thereby, while the 1st pinching body 221 can prevent interfering with the wire X, when the wire X is inserted between the open cutting blades 111 and 111, between the cutting blades 111 and 111 It is possible to prevent the wire X inserted into the cutting blades 111 and 111 from coming out. Therefore, the efficiency of the work of cutting the wire X, that is, the work of holding the wire X by the holding means 2 and 2 can be improved.

  Next, a second embodiment of the cutting tool according to the present invention will be described with reference to FIGS. 8-12, the part which attached | subjected the code | symbol same as the code | symbol of FIGS. 1-7 represents the structure or element same as 1st Embodiment.

  As shown in FIGS. 8 and 9, the cutting tool according to the present embodiment is configured to be detachable from the tool body 1 having a pair of cutting blades 111 and 111, and the tool body 1 is a wire (see FIG. 8). 8 and 9 (not shown in FIG. 9) is provided with a holder 2 ′ for holding the wire X when cutting X.

  The holder 2 ′ includes a holder body 21 that is mounted on the tool body 1 and a wire X that is cut by the pair of cutting blades 111 and 111 in order to hold the wire X when the tool body 1 cuts the wire X. A pair of holding means 22 ′ and 22 ′ for holding parts on both sides of the part are provided. Each holding means 22 ′ includes a pair of pressing bodies 221 ′ and 221 ′ having a pressing portion 221 a ′ for pressing the wire X.

  Each clamping body 221 ′ includes a shaft center portion 221 b that is pivotally attached to the holder body 21 so as to rotate about the shaft center of the support shaft portion 131 of the tool body 1. Moreover, each clamping body 221 'is provided with the contact part 221c abutted on the outer side of the blade member 11, and urged | biased so that it may rotate as the blade member 11 (cutting blade 111) rotates. .

  The pinching part 221a 'has elasticity. The pinching portion 221a 'is formed so as to generate a relatively large frictional force with the wire X to be pinched. For example, the pinching portion 221a 'is formed of rubber. Further, the clamping part 221a ′ is arranged so that the surface for clamping the wire X extends along the cutting blade 111 or protrudes inward from the cutting blade 111 (partly between the opened cutting blades 111, 111). Is provided).

  As the pair of cutting blades 111 and 111 close to each other so that the pair of cutting blades 111 and 111 are closed, the shaft center portion 221b allows each of the pressing bodies 221 'and 221' to approach each other. Rotate. Further, the shaft center part 221b regulates the displacement of the pair of sandwiching bodies 221 ′ and 221 ′ in the direction in which the pair of sandwiching sections 221a ′ and 221a ′ separate from each other, and the pair of sandwiching bodies 221. ', 221' is configured to be switchable to a state (a state in which the restriction is released) that can be displaced in the direction.

  Specifically, the shaft center portion 221b is configured so that the pinching body 221 ′ rotates only in one direction (a direction in which the pair of pinching portions 221a ′ and 221a ′ approach each other). There are provided restricting means (not shown and not numbered) for restricting rotation of the portions 221a ′ and 221a ′ in a direction away from each other, and release means (not shown and not assigned) for releasing the restriction.

  For example, the shaft portion 221b includes a claw portion (not shown and numbered) and a rack portion (not shown and numbered) connected to the pinching body 221 ′, and the claw portion hangs the rack portion. It is configured to be switchable between a stoppable state (position) and a non-lockable state (position).

  The abutting part 221c protrudes from the base body (not numbered) of the pinching body 221 'toward the blade member 11 (the other holding means 2). Specifically, the abutting part 221c couples the clamping members 221 'and 221' arranged in the same direction of the holding means 2 '. The contact portion 221c is brought into contact with the blade member 11 when each blade member 11 is displaced so as to close the cutting blade 111, so that the pair of pressing portions 221a ′ and 221a ′ approach each other. The pair of pinching bodies 221 ′ and 221 ′ are rotated.

  The contact portion 221c is configured to be detachable from the base of the pinching body 221 '. The contact portion 221c is removed from the base body of the pinching body 221 ′ so as to prevent the tool body 1 from interfering with the tool body 1 when the tool body 1 is housed in the housing portion 221. After 1 is once accommodated in the accommodating part 221, it is attached to the base | substrate of pinching body 221 '.

  The configuration of the cutting tool according to the present embodiment is as described above. Next, a method for cutting the wire X with the cutting tool according to the present embodiment will be described.

  First, as shown in FIG. 10A, the wire X is inserted between the opened cutting blades 111 and 111. Then, when each blade member 11 is rotated so that the cutting blades 111 and 111 are closed (in the direction of the arrow G in FIG. 10A), the outer sides of the blade members 11 come into contact with the contact portion 221c. Therefore, each clamping body 221 ′ rotates around the same axis as the blade member 11 (in the direction of arrow H in FIG. 10A).

  Therefore, as shown in FIG. 10 (b), each of the clamping bodies 221 'rotates integrally with the blade member 11, so that the pair of clamping parts 221a' and 221a 'approach each other. The wire X is compressed and compressed.

  Here, even if each blade member 11 is rotated so as to open the cutting blades 111 and 111 (in the direction of the arrow I in FIG. 10B) to reapply the force, as shown in FIG. Each pinching body 221 'is restricted from rotating by the shaft center portion 221b (regulating means). Thereby, since each pair of clamping parts 221a 'and 221a' continues to clamp the wire X while each cutting blade 111 is separated from the wire X, it is possible to prevent the wire X from moving.

  Then, when each blade member 11 is rotated so as to close the cutting blades 111, 111 again (in the direction of arrow J in FIG. 11A), each blade member 11 is separated from the contact portion 221c. Then, when only each blade member 11 is rotated and then each blade member 11 comes into contact with the contact portion 221c, each clamping body 221 ′ is centered on the same axis as the blade member 11 (FIG. 11 ( a) in the direction of the arrow K) and rotate integrally. Thereby, as shown in FIG.11 (b), the cutting blades 11 and 11 close and the wire X inserted between the cutting blades 11 and 11 can be cut | disconnected.

  Thereafter, each blade member 11 is rotated so as to open the cutting blades 11 and 11 (in the direction of the arrow L in FIG. 11B). At this time, since each pinching body 221 ′ is restricted from rotating by the shaft center portion 221b (regulating means thereof), as shown in FIG. 12A, a pair of pinching portions 221a ′, 221a 'Continues to pinch wire X.

  Then, when the restriction is released by the shaft center portion 221b (releasing means), the pair of pressure members 221a ′ and 221a ′ are separated from each other (in the direction of the arrow M in FIG. 12A). The body 221 'rotates. Thereby, as shown in FIG. 12B, the pinching force of the wire X by the both pinching portions 221a 'and 221a' can be released, and the wire X can be detached from the holding means 2 '.

  As described above, in the cutting tool according to the present embodiment, the pair of holding means 2 ′ and 2 ′ hold the portions on both sides in the portion of the wire X cut by the pair of cutting blades 111 and 111. Thereby, the wire X inserted between the opened cutting blades 111 and 111 can be cut by closing the cutting blades 111 and 111 while the pair of holding means 2 ′ and 2 ′ holds the wire X. Therefore, even if both hands are used when cutting, the wire X can be safely cut alone.

  Further, in the cutting tool according to the present embodiment, when the pair of blade members 11, 11 are rotated so as to close the cutting blades 111, 111, each pressing body 221 ′ is brought into contact with the blade member 11. Thereby, since each clamping body 221 'rotates integrally with the blade member 11, as the pair of cutting blades 111, 111 come close to each other, the pair of clamping parts 221a', 221a ' As a result, the wire X can be pinched by the pair of pinching portions 221a ′ and 221a ′.

  Therefore, since each pair of clamping members 221 ′ rotates in conjunction with the blade member 11, the pair of clamping parts 221a ′ and 221a ′ can hold the wire X, and thus, for example, the pair of cutting blades 11 , 11, it is not necessary to hold the wire X in the holding means 2 'in advance, and the wire X can be held as the wire X is cut. Can be further improved.

  Further, the cutting tool according to the present embodiment regulates the displacement of each of the pinching bodies 221 ′ in the direction in which the pair of pinching portions 221a ′ and 221a ′ separate from each other when cutting the wire X. Regardless of opening and closing of the cutting blades 111 and 111, the wire X can be continuously clamped by the pair of clamping portions 221a ′ and 221a ′. Then, after cutting the wire X, by releasing the restriction, the pinching of the wire X by the pair of pinching portions 221a ′ and 221a ′ can be released and the wire X can be removed from the holding means 2 ′. .
