  Hereinafter, a drop cable recovery device 1 according to an embodiment of the present invention will be described.

  In addition, the drop cable collection | recovery apparatus 1 which concerns on this embodiment, for example, as shown in FIG. 28, makes the lead-in wire (drop cable C) drawn from the telephone pole E where this line M1 is wired to the house H from the ground. It is an apparatus used for recovery. In the following description, the drop cable is sometimes simply referred to as a cable, but both indicate a lead-in line.

  FIG. 1 is an overall view showing a configuration of a drop cable recovery device 1 according to an embodiment of the present invention.

  The drop cable recovery device 1 includes an operation rod 30 that can be expanded and contracted according to the height of the drop cable to be cut from the ground, and a recovery unit 10 that cuts and holds the drop cable at the tip thereof.

  First, the operation rod 30 will be described with reference to FIGS. 1, 3, 6 and 7.

  As shown in FIG. 1, the operation rod 30 of the drop cable recovery device 1 shown in the present embodiment includes a first operation rod 31, a second operation rod 33 connected to the first operation rod 31, and a second operation rod. And a third operating rod 35 connected to the main body 33. In addition, the distal end of the third operating rod 35 has a connector 34 (see FIG. 3) to which the collection unit 10 is connected.

  The first operating rod 31 is a cylindrical rod-shaped member, and includes a substantially U-shaped step 32 in the vicinity of the base end portion 310. As shown in FIGS. 6 and 7, the step 32 is connected to the base end portion 310 of the first operating rod 31 so as to be rotatable about a rotation shaft 321. The step 32 is folded along the first operating rod 31 as shown in FIG. 6 when the drop cable collecting device 1 is stored. Then, when performing cable recovery using the drop cable recovery device 1, the rotation is rotated by a predetermined angle from the central axis of the first operating rod 31 around the rotation shaft 321 in the direction in which the tip end portion 322 is separated. Contact with the ground. In step 32, the operation angle of the operation rod 30 is maintained by being stepped on by the operator in this state.

  The second operating rod 33 is a cylindrical rod-like member having a diameter slightly smaller than that of the first operating rod 31, and is disposed in the first operating rod 31 so as to be slidable in the axial direction. When the second operating rod 33 extends a predetermined length from the first operating rod 31, the lock pin 36 protrudes and is fixed to the engagement hole of the first operating rod 31. A guide portion 37 is provided at the distal end portion 331 of the second operation rod 33 and the distal end portion 312 of the first operation rod 31. The guide portion 37 is for arranging an operation string 250 that is fixed and extended to a cutter portion 200 described later along the operation rod 30. Further, the second operation bar 33 includes a scale 39 indicating the length of the operation bar 30 in a part thereof.

  The third operating rod 35 is a cylindrical rod-like member having a diameter slightly smaller than that of the second operating rod 33, and is disposed in the second operating rod 33 so as to be slidable in the axial direction. When the third operating rod 35 is extended a predetermined length from the second operating rod 33, the lock pin 36 protrudes into the engagement hole of the second operating rod 33 and is fixed. A block-shaped connector 34 is bolted to the tip 351 of the third operating rod 35 (see FIG. 3). The third operating bar 35 is provided with a scale 39 indicating the length of the operating bar 30 at a part thereof, like the second operating bar 33.

  The operation rod 30 having such a configuration can adjust the amount of expansion / contraction of the first operation rod 31, the second operation rod 33, or the third operation rod 35 in accordance with the height of the lead-in line that needs to be collected. . A plurality of engagement holes may be provided so that the operation rod 30 can be adjusted to a desired length. Further, the drop cable can be pushed up as necessary. In addition, since the scale 39 is provided, the approximate height to the lead-in line at that time can be measured. Further, since the base end portion 310 of the first operating rod 31 is provided with the step 32, even if it is difficult to support the operating rod 30 only by the hand of the operator, the step 32 is performed. The operation rod 30 can be supported. Further, since the step 32 is structured to be supported by the legs, it is possible to operate the operation rod 30 and an operation string 250 described later using both hands. For this reason, it is possible to ensure safety in the collecting operation and to reduce the worker's fatigue.

  In addition, in this embodiment, although the operation rod 30 is set as the structure which connects three, the structure of this operation rod 30 is not restricted to this. For example, it is possible to increase the number of operation rods connected to the height of the lead-in line, or to increase the length of one operation bar. In addition, when the height of the lead-in line is determined to some extent, it is possible to employ several types of operation rods with no connection. The configuration of the operation bar can be appropriately adjusted in consideration of the situation in the work area. Further, the material of the operation rod is preferably lightweight, has a certain degree of strength, and is insulative. For example, a resin material or FRP can be employed.

  Next, the structure of the collection unit 10 will be described in more detail with reference to FIGS. 1, 2, and 3. In FIG. 1 and FIG. 2, a virtual line P indicated by a one-dot chain line bisects a grip plate 110 described later and is provided along the axis of the operation rod 30. Moreover, the collection | recovery part 10 of the drop cable collection | recovery apparatus 1 shown in FIG. 1, FIG. 2 has shown the fixed position.

The collection unit 10 includes a holding unit 100 that holds a drop cable to be cut and fixes the drop cable when the drop cable is cut, and a cutter unit 200 that cuts the drop cable fixed by the holding unit 100. The arrangement of the grip part 100 and the cutter part 200 will be briefly described. As shown on the left side of FIG. 3, a fixed shaft 40 extends from a connector 34 provided at the distal end of the operation rod 30 in a direction orthogonal to the axial direction of the operation rod 30. The cutter unit 200 and the gripping unit 100 are connected to the fixed shaft 40 in order.

  The gripping plate 110 is an arrow-blade plate-like member, and has a substantially V-shaped cable guide 111 inside and a U-shaped groove portion 112 connected to the V-shaped top of the cable guide 111. The grip plate 110 is fixed to the tip of the operation rod 30 by the fixed shaft 40 along the central axis at a position where the grip plate 110 is substantially parallel to the central axis of the operation rod 30.

  As shown in FIG. 2, the cable guide 111 is formed substantially symmetrically with respect to the imaginary line P, and is sandwiched between the guide protrusion L on the left side and the guide protrusion R on the right side in the figure, and is formed on the upper side of the groove portion 112 in the figure. It has a substantially V-shaped space. The guide protrusion L has a first inclined portion 115L, a stepped portion 113L, and a second inclined portion 117L on the cable guide 111 side. The guide protrusion R has a first inclined portion 115R, a stepped portion 113R, and a second inclined portion 117R on the cable guide 111 side.

  The cable guide 111 is formed wider than the groove portion 112 on the upper side of the groove portion 112 in the drawing, and smoothly introduces the drop cable C to be cut. Further, by providing step portions 113L and 113R having a predetermined width between the first inclined portions 115L and 115R and the second inclined portions 117L and 117R of the guide protrusion L and the guide protrusion R, the operation rod 30 is provided. The drop cable C that is operated and guided to the cable guide 111 of the holding plate 110 is restricted from coming out of the holding plate 110. In other words, the step portions 113L and 113R function as a return of the drop cable introduced into the cable guide 111. Note that the width, inclination angle, and length of the first inclined portions 115L and 115R, the second inclined portions 117L and 117R, and the step portions 113L and 113R are not particularly limited, and the cables to be collected are laid. It is designed appropriately in consideration of the current situation and the thickness of the cable to be recovered.

  As shown in FIG. 2, the groove 112 is provided on the proximal end side of the cable guide 111. The groove portion 112 is a concave portion cut out in a substantially U shape. The groove 112 is a space for finally holding the drop cable C guided from the cable guide 111 on the gripping plate 110. The size of the groove 112 is not particularly defined, but is appropriately designed in consideration of the relationship with the held drop cable. In the present embodiment, the groove portion 112 is formed so as to be able to accommodate, for example, so-called one to six pairs of drop cables that are generally employed as telephone lines.

  As shown in FIG. 2, the removal prevention tool 130 includes a first pressing tool 131, a tension coil spring (return spring) 133 that is a first urging member, and a pivot that is a first pivot end. A shaft 135 is provided. The first pressing member 131 is a substantially S-shaped plate-like member, and includes a distal end portion 134 connected to the rotation shaft 135, a proximal end portion 136 provided on the opposite side of the distal end portion 134, and a distal end portion 134. And a connecting portion 132 connecting the base end portion 136. The distal end portion 134 is coupled to the lower side of the figure with respect to the stepped portion 113R of the guide projection R of the gripping plate 110 so as to be rotatable by a rotation shaft 135. For example, the communication part 132 is inclined along the second inclined part 117R. At this time, the base end portion 136 is provided at a connection position (opening portion 120) between the groove portion 112 and the cable guide 111. In addition, one end of the tension coil spring 133 is fixed to the distal end portion 134 further to the distal end side than the attachment position of the rotation shaft 135. The other end of the tension coil spring 133 is fixed at a predetermined position of the grip plate 110. The tension coil spring 133 generates a biasing force in the direction in which the opening 120 of the groove 112 opens the base end portion 136 of the first pressing member 131. A base end portion 136 of the first pressing tool 131 is locked to a distal end portion 154 of the first holding portion 150 described later, and a base 139 of the base end portion 136 of the first pressing tool 131 is substantially orthogonal to the virtual line P. It is supported at the position to do.

  Such a slip-off prevention tool 130 is rotatably supported with the rotation shaft 135 as a rotation end portion, and is a closed position where the base end portion 136 of the first presser 131 is closed with the opening 120 of the groove portion 112 ( The position of the first presser 131 is changed to a fixed position) and an open position where the opening 120 of the groove 112 is opened. That is, it functions as an open / close gate of the groove 112. Specifically, as shown in FIG. 2, when the base end 136 is pressed downward with a predetermined pressure by the drop cable guided to the cable guide 111, the disconnection prevention tool 130 is opened in the groove 112. 120 is opened, and the drop cable is inserted into the groove 112. When the drop cable is inserted into the groove 112, the pressure applied to the first pressing member 131 is released. Then, due to the biasing force of the tension coil spring 133, the first pressing member 131 returns to a predetermined position and closes the opening 120 of the groove 112. In addition, the bottom side 139 of the first pressing tool 131 of the present embodiment is formed by a straight line and is substantially orthogonal to the side side 119 of the groove portion 112. With this arrangement, when the recovery unit 10 is moved along the drop cable while being introduced into the groove 112 and holding the drop cable, the held drop cable is near the opening 120 of the groove 112. Thus, it is possible to prevent the first presser 131 from being stuck between the proximal end portions 136 of the first presser 131 and moving. In this embodiment, the tension coil spring 133 is adopted as the biasing member. However, the biasing member is not limited to this, and has a certain degree of elastic force, and the first pressing member 131 is the opening of the groove 112. What is necessary is just to hold | maintain at the position of 120 and to be able to function as a drop cable removal prevention tool.

Further, the end portion of the distal end portion 154 comes into contact with the end portion of the base end portion 136 of the first presser 131 and restricts the rotation of the first presser 131. The second pressing member 151 is provided with a torsion coil spring 155 on the rotating shaft 153 in order to resist the pressing force from the first pressing member 131. The torsion coil spring 155 biases the second pressing member 151 disposed on both surfaces of the gripping plate 110 in the direction from the back portion 158 to the groove portion 112. That is, the torsion coil spring 155 biases the second pressing member 151 toward the virtual line P, and maintains the posture of the standby position against the pressing force of the first pressing member 131.

  The two second pressing members 151 are disposed to face both surfaces (the first surface 114 and the second surface 116) of the grip plate 110 with the grip plate 110 interposed therebetween. The postures of the two second pressing members 151 are held by one torsion coil spring 155. In addition, the shape and size of the flange portion 159 of the second presser 151 are appropriately set to a shape that can efficiently hold the cable in consideration of the thickness and material of the cable inserted into the groove portion 112.

Specifically, the second side stay 175 is connected to the second operation arm 223 by a rotation shaft 172 (second rotation fulcrum) so as to be rotatable. On the other hand, the other end of the second side stay 175 is connected via a connecting shaft portion 176 so as to be movable along the guide hole 178 and the guide hole 178 of the center stay 171.

  The link mechanism 170 includes a tension coil spring 177 and a wire 179 as a pulling member. Specifically, the second side stay 175 is connected to the connecting shaft portion 176 side via the connecting portion 156 of the second pressing member 151 of the first holding portion 150 via the tension coil spring 177. Further, the second side stay 175 is connected to the connecting portion 156 of the second pressing tool 151 via the wire 179 on the rotating shaft 172 side.

  The link mechanism 170 links the cable cutting operation by the cutter unit 200 and the movement operation of the first holding unit 150 to the holding position of the second pressing member 151 by having the above-described configuration. The link mechanism 170 holds the second pressing member 151 by the action of the tension coil spring 177 before the first blade 211 and the second blade 221 of the cutter unit 200 come into contact with the drop cable (before cutting). The drop cable can be clamped. Then, after entering the cutting operation, the wire 179 acts to securely fix the second presser 151.

  Next, the collecting operation of the lead-in cable using the drop cable collecting apparatus 1 will be described with reference to FIGS.

  FIG. 8 is a front view showing a state where the drop cable C to be cut is inserted into the cable guide 111. FIG. 9 is a front view showing a state where the first presser 131 of the drop prevention tool 130 is pressed by the drop cable C, the opening 120 of the groove 112 is opened, and the drop cable C is inserted into the groove 112. . FIG. 10 is a front view showing a state in which the first pressing tool 131 returns to the closed position (fixed position) by the urging force applied to the first pressing tool 131 after the drop cable C is inserted into the groove portion 112. . FIG. 11 is an explanatory diagram showing a state in which the first holding unit 150 starts to move in conjunction with the cutting operation of the drop cable C of the cutter unit 200 while the cutter unit 200 is operated. FIG. 12 is a front view showing a state in which the drop cable C is cut by the cutter unit 200 after the second presser 151 of the first holding unit 150 holds the drop cable C. FIG. FIG. 13 is a front view showing a state where the cutter unit 200 has returned to the non-cutting position (fixed position) after the drop cable C is cut.

  First, the drop cable C, which is a lead-in wire to be removed and collected, is confirmed. The operation target 30 of the drop cable collection device 1 is extended from the ground to the drop cable C to be collected and accessed to the drop cable C to be collected. As shown in FIG. 8, the grip plate 110 of the collection unit 10 provided at the distal end 351 of the operation rod 30 is brought close to the drop cable C, and the drop cable C is introduced into the cable guide 111.

  Subsequently, in a state where the drop cable C is introduced inside the cable guide 111, the groove portion 112 of the drop cable collection device 1 is moved toward the drop cable C. At a position where the grip plate 110 is substantially orthogonal to the drop cable C, the first pressing tool 131 of the drop prevention tool 130 and the drop cable C are brought into contact with each other. As shown in FIG. 9, the first pressing member 131 is rotated in the direction of the arrow toward the groove portion 112 by being pressed from the inclined side 137 side with a pressure exceeding the urging force of the tension coil spring 133. The first pressing tool 131 moves to the open position. In other words, the opening 120 of the groove 112 opens and communicates with the cable guide 111. The drop cable C is inserted into the groove portion 112 so as to push the first pressing member 131 to the open position.

  Next, as shown in FIG. 10, when the drop cable C is inserted to a predetermined depth of the groove 112, the drop cable C and the first pressing tool 131 are separated from each other, and the pressing force to the first pressing tool 131 is increased. Disappear. Then, the first pressing member 131 rotates in the direction of arrow T by the urging force of the tension coil spring 133, moves in a direction to close the opening 120 of the groove 112, and comes into contact with the second pressing member 151. Stop at the closed position (fixed position). As a result, the drop cable C is accommodated in the groove 112 and is prevented from being removed by the removal preventing tool 130.

  In this state, the drop cable C is not fixed in the space of the groove portion 112. For this reason, the drop cable recovery apparatus 1 can move freely along the drop cable C.

  For this reason, for example, when a plurality of lead wires are complicatedly wired and it is difficult to accurately select the drop cable C to be cut, the drop cable C is wired alone as shown in FIG. The operation up to FIG. 10 is performed at the connection end on the house H side. Thereafter, the drop cable collecting device 1 is moved along the drop cable C, and the cutting operation can be performed at a desired position of the drop cable C. Moreover, in the drop cable collection | recovery apparatus 1 shown in this embodiment, the base 139 of the base end part 136 of the 1st pressing tool 131 is formed with the straight line. This prevents the drop cable C from being sandwiched between the side 119 and the bottom 139 of the groove 112 when the drop cable recovery device 1 is moved along the drop cable C.

  In the present embodiment, a drop cable C stretched on a telephone pole or the like is assumed, but the drop cable has a predetermined weight, and is pushed into the groove 112 by pushing away the first pressing member 131. If it is a drop cable that can be applied, it can also be applied to a drop cable in a hanging state.

  Subsequently, the cutting operation by the cutter unit 200 is started. At this time, the operation cord 250 (see FIG. 1) is pulled toward the base end portion 310 of the operation rod 30 indicated by an arrow in FIG. By the operation of the operation cord 250, the first cutter member 210 and the second cutter member 220 are rotated in opposite directions from the fixed positions shown in FIG. In conjunction with this operation, the link mechanism 170 starts operation. The first side stay 173 rotates about the rotation shaft 174 as a rotation center, and slides the connecting shaft portion 176 connected to the guide hole 178 of the center stay 171 toward the base end portion 310 of the operation rod 30. Let Further, in conjunction with the first side stay 173, the second side stay 175 operates in the same manner.

  In conjunction with the operation of the second side stay 175, the tension coil spring 177 connected to the second pressing member 151 is pulled toward the base end portion 310. By this operation, the second pressing member 151 rotates toward the groove portion 112 using the rotation shaft 153 as a rotation end. Thereby, the drop cable C is clamped between the flange portion 159 provided at the distal end portion 154 of the second pressing member 151 and the inner bottom portion 118 of the groove portion 112 (clamping position).

  Here, at the stage where the drop cable C is sandwiched, the first blade 211 and the second blade 221 of the cutter unit 200 are not in contact with the drop cable C. In other words, the cutting operation of the cutter unit 200 is adjusted to be performed after the drop cable C is reliably held by the first holding unit 150. Further, as shown in FIG. 3, the second pressing member 151 is arranged on both the first surface 114 and the second surface 116 with the gripping plate 110 interposed therebetween. Since the drop cable C is securely held between the two second pressing members 151, the drop cable C accommodated between the grip portion 100 and the cutter portion 200 is bent, and the drop cable C is removed from the space portion 230 of the cutter portion 200. C does not come off. Thereby, a cutting operation can be performed at a position where the most force of the cutter unit 200 is transmitted efficiently. Moreover, since it cuts after hold | maintaining, a blade does not slip.

  When the operation cord 250 (see FIG. 1) is further pulled in the direction of the arrow, the drop cable C held by the first holding unit 150 is cut by the cutter unit 200 as shown in FIG. Thus, it is necessary to hold the drop cable C firmly during the cutting operation. Therefore, the second presser 151 securely holds the drop cable C by stretching the wire 179 in addition to the tension coil spring 177.

  The operation cord 250 is further pulled from this state, and the interlocking second pressing member 151 rotates toward the clamping position about the rotation shaft 153. At this time, as shown in FIG. 11, the distal end portion 154 of the second pressing member 151 presses the proximal end portion 136 of the first pressing member 131, and the first pressing member 131 is moved by a predetermined amount. Then, as shown in FIG. 12, the contact between the distal end portion 154 of the second pressing member 151 and the proximal end portion 136 of the first pressing member 131 is released. When the contact between the distal end portion 154 and the proximal end portion 136 is released, the first pressing member 131 rotates toward the closed position (fixed position) by the urging force of the tension coil spring 133. Then, the base end portion 136 of the first presser 131 that has started to rotate to the closed position by the biasing force of the tension coil spring 133 is engaged with the recess 157 provided in the distal end portion 154 of the second presser 151. And fixed.

  And as shown in FIG. 13, the cutting | disconnection operation | movement of the drop cable C by the cutter part 200 is complete | finished. When the cutting of the drop cable C is finished, the operation cord 250 of the cutter unit 200 is loosened, and the first cutter member 210 and the second cutter member 220 are not cut (fixed position) by the biasing force of the torsion coil spring 240. Return to. On the other hand, the second pressing member 151 of the first holding unit 150 of the grip plate 110 is fixed at the holding position. For this reason, the drop cable C after cutting does not come off due to the operation of the operation cord 250, and there is no risk that the drop cable C after cutting will fall to a person or a private house.

  Subsequently, the release operation of the drop cable D from the drop cable collection device 1 when the drop cable D that is not a cutting target is inserted into the groove portion 112 of the drop cable collection device 1 will be described with reference to FIGS. 14, 15, and 16. To do.

  FIG. 14 shows the drop cable collection device 1 in a state where the drop cable D is inserted into the groove 112 from the cable guide 111 and the drop cable D is held as shown in FIG. The drop cable D fixed to the utility pole is a cable that is stretched with a certain tension.

  First, as shown in FIG. 15, the recovery unit 10 of the drop cable recovery device 1 is moved toward the base end portion 310 of the operation rod 30 (see FIG. 1) (moves the recovery unit 10 downward in the figure). ). By this operation, the drop cable D and the base 139 of the base end portion 136 of the first pressing member 131 come into contact with each other. Further, when the operating rod 30 is pulled downward and the drop cable recovery device 1 is moved toward the base end portion 310, the drop cable D presses the first pressing member 131 in the direction of arrow I. As a result, the second pressing member 151 is rotated against the urging force of the torsion coil spring 155 provided on the second pressing member 151 that locks the first pressing member 131. Is pivoted in the direction away from the groove 112 (arrow J). By this operation, as shown in FIG. 15, the engagement between the first pressing member 131 and the second pressing member 151 is released, and the base end portion 136 of the first pressing member 131 rotates in the direction of arrow I. And moves over the tip 154 of the second pressing member 151. Further, as shown in FIG. 16, the drop cable collecting device 1 is operated to rotate the first pressing tool 131 in the direction of the arrow. Thereby, a gap through which the drop cable D can pass is formed between the second inclined portion 117 </ b> L of the grip plate 110 and the base end portion 136 of the first presser 131. In this state, the operation of the operation rod 30 is performed to remove the drop cable D from the cable guide 111, thereby terminating the release operation of the drop cable D. By the above-described releasing operation, the drop cable D that is erroneously inserted into the groove 112 of the drop cable collection device 1 can be detached from the drop cable collection device 1.

  As described above, the drop cable recovery device 1 according to the present embodiment can remove the drop cable D once held from the gripper 100. For this reason, it is possible to flexibly cope with the case where the drop cable is accidentally taken in, or when the operation of collecting the cable is performed again due to the entanglement of the drop cable.

  Next, a recovery operation in the case of recovering the drop cable F that is hung from the telephone pole using the drop cable recovery device 1 will be described with reference to FIG. For example, the drop cable F may be in a state where one end of the drop cable is cut and is hung from a telephone pole. In such a case, the first presser 131 cannot be pushed toward the inner bottom portion 118 of the groove portion 112 by the weight of the drop cable F.

  Therefore, before starting the operation of collecting the drop cable F, the operator preliminarily moves the first pressing tool 131 of the removal preventing tool 130 of the grip portion 100 away from the groove portion 112 (arrow). Direction). Before the first presser 131 rotates once, the bolt 138 that fixes one end of the tension coil spring 133 provided on the grip plate 110 abuts on the base end portion 136. In other words, as shown in FIG. 17, the first presser 131 is in a state of swinging freely to a position where it comes into contact with the bolt 138 with the rotation shaft 135 as a fulcrum. Further, since the position of the first pressing tool 131 is moved, the cable guide 111 communicates with the groove 112 (the opening 120 of the groove 112 is opened).

  The recovery unit 10 of the drop cable recovery device 1 with the opening 120 opened is brought close to the drop cable F, and the drop cable F is guided to the cable guide 111. Since the opening 120 of the groove 112 is open, the drop cable F passes through the cable guide 111 and enters the groove 112 as it is.

  Subsequently, the cutting operation by the cutter unit 200 is started. In addition, since the cutting | disconnection operation | movement of the drop cable F by the cutter part 200 is the operation | movement similar to the above-mentioned FIG.11 and FIG.12, the detailed description is abbreviate | omitted. Here, the first presser 131 of the removal preventing tool 130 is turned to the right side in FIG.

  Even when the drop cable F cannot be inserted into the groove portion 112 by using the collection unit 10 arranged in this manner, the drop prevention device 130 can be pushed away by the tension of the drop cable or the weight of the cable. The cable F can be cut and collected.

  Next, a first modification of the recovery unit 10 of the drop cable recovery device 1 will be described with reference to FIGS. 18, 19, 20, and 21. FIG. In addition, the collection | recovery part 10a shown in FIG. 18 shows the state in a fixed position, and the collection | recovery part 10a shown in FIG. 19 has shown the state in cutting | disconnection operation | movement. In the first modification, the same members as those of the recovery unit 10 of the drop cable recovery device 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The difference between the collection unit 10a described as the first modification and the collection unit 10 is that, as shown in FIG. 18, the collection unit 10a has a second holding unit on the first surface 114 side of the grip plate 110. 500 is provided.

  The second holding unit 500 will be described. The second holding unit 500 includes a third pressing tool 510, a pressing member 540, and a lock member 560. The third presser 510 is an elongated plate-like member having bent portions at both ends. The end of the third presser 510 on the side of the groove 112 is referred to as a distal end 530, and the opposite side is referred to as a proximal end 550. The third presser 510 passes through the fixed shaft 40 that is the third rotation end at a position near the distal end 530 of the connecting portion 570 on the first surface 114 side of the gripping plate 110 so as to be rotatable, It is connected. Further, the third pressing member 510 may be provided with a spring member (not shown) in order to maintain the posture at a fixed position. The pressing member 540 is a protrusion-like member provided on the surface of the first operation arm 213 of the cutter unit 200 on the side facing the third pressing tool 510. The pressing member 540 comes into contact with the locking portion 520 on the base end portion 550 side of the third pressing tool 510. As shown in FIGS. 20 and 21, the lock member 560 includes a lock pin 561 and a coil spring 562. The lock member 560 is provided so as to protrude and retract toward the first surface 114 in the thickness direction of the grip plate 110.

  Next, the holding operation of the drop cable C (see FIG. 8) of the second holding unit 500 will be described in detail. The operation of inserting the drop cable C into the groove 112 and the operation of cutting the drop cable C are the same as those of the drop cable collection device 1, and thus detailed description thereof is omitted.

  When the drop cable C is inserted into the groove 112, the recovery unit 10a shifts to a cutting operation of the drop cable C. When the operation string 250 (see FIG. 2) is pulled, the recovery unit 10a rotates the second pressing member 151 to clamp the drop cable C before being cut by the cutter unit 200.

  In the third presser 510, the locking portion 520 provided at the base end portion 550 is pressed by the pressing member 540 that is interlocked with the rotation operation of the first operation arm 213 of the cutter unit 200. As a result, the third presser 510 rotates about the fixed shaft 40. When the first operation arm 213 is further rotated, the third presser 510 is also interlocked with the first operation arm 213 and rotates the distal end portion 530 toward the groove portion 112.

  As shown in FIG. 19, when the cutter unit 200 moves to the cutting position, the lock member 560 and the third presser 510 that are arranged to overlap the third presser 510 at the fixed position shown in FIG. Overlap is eliminated. When the overlap with the third pressing tool 510 is eliminated, the pressing force applied to the coil spring 562 is eliminated, and the lock pin 561 protrudes from the grip plate 110. At this time, the distal end portion 530 of the third presser 510 holds the drop cable C accommodated in the groove portion 112 from the side 119 side of the groove portion 112.

  As described above, at this time, the first holding unit 150 also moves the second pressing member 151 to the clamping position in conjunction with the cutting operation of the cutter unit 200, and clamps the drop cable.

  Thereafter, when the tension of the operation cord 250 is loosened, the cutter unit 200 returns from the cutting position to the non-cutting position (fixed position) by the restoring force of the torsion coil spring 240 (see FIG. 2). On the other hand, in the first holding part 150, the base end part 136 of the first presser 131 that has started to rotate to the closed position (fixed position) is provided at the distal end part 154 of the second presser 151. The drop cable C is clamped by being engaged with and fixed to the recess 157. In addition, the second holding unit 500 continuously holds the drop cable C by restricting the rotation of the third pressing member 510 by the protruding lock member 560. In addition, the third presser 510 of the second holding unit 500 firmly sandwiches the drop cable C with the side 119 of the groove 112. For this reason, depending on the type of drop cable to be collected, it is bent, pinched and fixed.

  The collecting unit 10a having such a configuration reliably holds the drop cable C even when the drop cable C to be collected is heavy and the first holding unit 150 alone cannot obtain a sufficient holding force. It is possible. Moreover, by providing the holding parts of the first holding part 150 and the second holding part 500, it is possible to safely recover the drop cable even when one of them fails and does not move. In addition, by providing the second holding unit 500, for example, when collecting the drop cable F having no tension, the first holding unit 150 cannot be locked in the holding position after the cutting operation. However, in the collection unit 10 a to which the second holding unit 500 is added, the drop cable F can be held by the second holding unit 500. For this reason, there is no possibility that the drop cable being collected is dropped on a person or a building. In the present embodiment, the lock member 560 is formed so as to protrude and retract using the coil spring 562, but is not limited to this configuration. For example, other elastic members can be incorporated.

  Next, a second modification of the recovery unit 10 of the drop cable recovery device 1 will be described with reference to FIGS.

  As shown in FIG. 22, the difference in configuration between the collection unit 10b described as the second modification and the collection unit 10 is that the grip plate 110b of the collection unit 10b has a first rotation shaft 174b. The cutter member 210 and the first side stay 173b are connected. On the other hand, the grip plate 110 of the collection unit 10 is not connected at such a position. Further, the cable guide 111b of the grip plate 110b does not have the first inclined portions 115L and 115R (see FIG. 2) and the step portions 113L and 113R (see FIG. 2). Moreover, the link mechanism 170b of the collection | recovery part 10b differs in the point which does not have the center stay 171 (refer FIG. 2) and the wire 179 (refer FIG. 2). The tension coil spring 177b is also different in that the connecting portion 156 and the connecting shaft portion 176b of the second presser 151 are connected. Further, the first presser 131b of the removal preventing tool 130b of the recovery part 10b is different in that the base 139b of the base end part 136b is formed in an arc shape.

  Next, the collecting operation of the drop cable C using the collecting unit 10b according to the second modification will be described with reference to FIGS. In the recovery unit 10b, the same members as those in the recovery unit 10 of the drop cable recovery device 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 22 is a front view showing a state where the drop cable C to be cut is inserted into the cable guide 111b. FIG. 23 is a front view showing a state in which the first presser 131b of the drop prevention tool 130b is pressed by the drop cable C, the opening 120b of the groove 112b is opened, and the drop cable C is inserted into the groove 112b. . FIG. 24 is a front view showing a state in which the first pressing tool 131b returns to the closed position (fixed position) by the urging force applied to the first pressing tool 131b after the drop cable C is inserted into the groove portion 112b. . FIG. 25 is an explanatory diagram illustrating a state in which the first holding unit 150 starts to move in conjunction with the operation of operating the cutter unit 200b and the cutting operation of the drop cable C of the cutter unit 200b. FIG. 26 is a front view illustrating a state in which the drop cable C is cut by the cutter unit 200b after the second presser 151 of the first holding unit 150 holds the drop cable C. FIG. FIG. 27 is a front view showing a state where the cutter unit 200b has returned to the non-cutting position (fixed position) after the drop cable C is cut.

  As shown in FIG. 22, the grip plate 110b of the collection part 10b provided on the connector 34 of the operation rod 30 (see FIG. 3) is brought close to the drop cable C, and the drop cable C is introduced into the cable guide 111b. Note that the cable guide 111b of the second modified example does not have the first inclined portions 115L and 115R and the step portions 113L and 113R at the tip thereof. For this reason, the grip plate 110b can be made lighter than the grip plate 110 of the collection unit 10.

  Subsequently, in a state where the drop cable C is introduced inside the cable guide 111b, the groove portion 112b is moved toward the drop cable C. At a position where the grip plate 110b is substantially orthogonal to the drop cable C, the first presser 131b of the drop prevention tool 130b and the drop cable C are brought into contact with each other. As shown in FIG. 23, the first pressing member 131 is pressed with a force exceeding the urging force of the tension coil spring 133b, and thereby toward the groove portion 112b with the rotation shaft 135b provided at the tip end portion 134b as an axis. Rotate in the direction of the arrow. The first pressing tool 131b moves to the open position. In other words, the opening 120b of the groove 112b opens and communicates with the cable guide 111b. The drop cable C is inserted into the groove 112b so as to push the first pressing member 131b to the open position.

  Next, as shown in FIG. 24, when the drop cable C is inserted to a predetermined depth of the groove 112b, the drop cable C and the first pressing tool 131b are separated from each other, and the pressing force to the first pressing tool 131b is increased. Disappear. Then, the first pressing member 131b rotates upward in the figure by the urging force of the tension coil spring 133, moves in a direction to close the opening 120 of the groove 112, and comes into contact with the second pressing member 151. Stop at the closed position (fixed position). Thereby, the drop cable C is accommodated in the inside of the groove part 112, and a drop prevention tool 130b prevents the drop cable C from coming off.

  In this state, the drop cable C is not fixed in the space of the groove portion 112, and the collection unit 10b can move freely along the drop cable C.

  For this reason, the recovery unit 10b of the second modified example also moves the recovery unit 10b to a desired cutting position after selecting the drop cable C, similarly to the drop cable recovery device 1 provided with the recovery unit 10. C cutting work can be performed.

  Subsequently, as shown in FIG. 25, the cutting operation by the cutter unit 200b is started. When an operation string (not shown) arranged in the same manner as the collecting unit 10 is pulled, the second cutter member 220 rotates in a state where the first cutter member 210 fixed to the grip plate 110b is in a fixed position. To start. In conjunction with this operation, the link mechanism 170b starts to operate. The first side stay 173b rotates about the rotation shaft 174b. The second side stay 175b is connected to the first side stay 173b by a connecting shaft portion 176b, and rotates around the rotation shaft 172b in conjunction with the rotation of the second cutter member 220b. At this time, the tension coil spring 177b coupled to the coupling shaft portion 176b is pulled in a direction away from the second pressing member 151. By pulling the tension coil spring 177b, the second pressing member 151 rotates toward the groove 112b using the rotation shaft 153 as a rotation end. Thereby, the drop cable C is clamped between the flange portion 159 provided at the distal end portion 154 of the second presser 151 and the inner bottom portion 118b of the groove portion 112b (clamping position).

  Here, at the stage where the drop cable C is held, the first blade 211 (see FIG. 4) and the second blade 221 (see FIG. 4) of the cutter unit 200b are not in contact with the drop cable C. Or even if it contact | abuts, the cutting | disconnection of the drop cable C is not started. In other words, the cutting operation of the cutter unit 200b is adjusted to be performed after the drop cable C is reliably held by the first holding unit 150. For this reason, the cutting operation can be performed at a position where the most force of the cutter unit 200b is efficiently transmitted. Moreover, since it cuts after hold | maintaining, a blade does not slip.

  As shown in FIG. 26, when an operation cord (not shown) is further pulled, the drop cable C held by the first holding unit 150 is cut. Further, in conjunction with the operation of pulling the operation cord (not shown), the second pressing member 151 rotates in the direction of the arrow about the rotation shaft 153 toward the clamping position. At this time, the distal end portion 154 of the second pressing tool 151 presses the proximal end portion 136b of the first pressing tool 131b, and moves the first pressing tool 131b to the open position so as to retract from the groove portion 112. At a certain point where the first presser 131b has moved by a predetermined amount, the contact between the distal end portion 154 of the second presser 151 and the base end portion 136b of the first presser 131b is released. When the contact between the distal end portion 154 and the base end portion 136b is released, the first pressing member 131b is rotated toward the closed position (fixed position) by the urging force of the tension coil spring 133b. Then, the base end portion 136b of the first presser 131b that has started to rotate to the closed position is engaged with and fixed to the recess 157 provided in the distal end portion 154 of the second presser 151.

  Then, as shown in FIG. 27, the cutting operation of the drop cable C by the cutter unit 200b is completed. When the cutting of the drop cable C is completed, the operation string (not shown) of the cutter unit 200b is loosened, and the urging force of the torsion coil spring 240 (not shown) is restored to restore the first cutter member 210b and the second cutter member 210b. The cutter member 220b returns to the non-cutting position (fixed position). On the other hand, the second pressing member 151 of the first holding unit 150 of the grip plate 110b is fixed at the holding position. For this reason, the cut drop cable C is not disconnected by the operation of the operation cord (not shown), and the cut drop cable C is prevented from dropping into a person or a private house.

Moreover, the 1st holding | maintenance part 150c interlock | cooperates with the cutting | disconnection operation | movement of the cutter part 200 via the link mechanism 170c.

  That is, before the cutting operation of the drop cable C, the first holding unit 150c places the second pressing members 151c and 151d at the standby position. When the cutting operation is started, the first holding unit 150c moves the second pressing members 151c and 151d to the clamping position, and the drop cable C introduced into the groove 112 is connected to the inner bottom 118 of the groove 112. Hold between.

  Here, one second pressing member 151c has a hook shape as shown in FIG. The second pressing member 151c includes a base end portion 152c connected to the first gripping plate 110c by a rotation shaft 153c, and a distal end portion 154c including a flange portion 159c that sandwiches the drop cable C.

Furthermore, the second pressing member 151c includes a connecting portion 156c that is connected to the link mechanism 170c at the base end portion 152c. Further, the second pressing member 151c includes a protruding knob 161 on the opposite side facing the flange 159c.

  The other second pressing tool 151d has a hook shape that is substantially the same shape as the second pressing tool 151c as shown in FIG. The second pressing member 151d has a base end portion 152d connected to the first gripping plate 110c via a rotation shaft 153c, and a distal end portion 154d including a flange portion 159d that sandwiches the drop cable C. Furthermore, the base end portion 152d includes a connecting portion 156c that is connected to the link mechanism 170c.

  Further, the distal end portion 154d is engaged with the base end portion 136 of the first presser 131, and a recess 157d for fixing the second presser 151d at the clamping position is provided on the outer periphery opposite to the flange portion 159d. .

  As shown in FIGS. 29 and 30, the second pressing members 151c and 151d are directed upward on the guide protrusion L side of the first holding plate 110c and the second holding plate 110d in the standby position (fixed position). The second pressing members 151c and 151d are connected to the rotating shaft 153 at positions where the front end portions 154c and 154d of the second pressing members 151c and 151d face. In addition, the flanges 159c and 159d of the second pressing members 151c and 151d are arranged at a position facing the groove 112 side at this time.

  The rotation shaft 153c is a connecting member that rotatably connects the two second pressing members 151c and 151d. The torsion coil spring 155c is provided on the first surface 114c side of the first grip plate 110c of the rotation shaft 153c. The torsion coil spring 155c biases the second pressing member 151c from the back portion 158c side to the groove portion 112. Further, the torsion coil spring 155c biases the second pressing member 151d connected to the second pressing member 151c and the rotation shaft 153c from the back portion 158c side to the groove portion 112.

  Due to the biasing force of the torsion coil spring 155c, the second pressing member 151d on the second gripping plate 110d side comes into contact with the base end portion 136 of the first pressing member 131, and the first pressing member 131 moves upward in the figure. (See FIG. 30).

  That is, the torsion coil spring 155c urges the second pressers 151c and 151d toward the first presser 131, and maintains the posture of the standby position against the pressing force of the first presser 131. In the present embodiment, the two second pressing members 151c and 151d are arranged to face each other with the first gripping plate 110c and the second gripping plate 110d interposed therebetween, and the posture thereof is set by one torsion coil spring 155c. Retained.

  The connecting portion 156c is a rod-like member that connects the second presser 151c and the second presser 151d. And the connection part 156c is connected with the link mechanism 170c via the wire 179c, as shown in FIG.

  In addition, the shape and size of the flange portions 159c and 159d of the second pressing members 151c and 151d can be efficiently held in consideration of the thickness and material of the cable inserted into the groove portion 112. It is designed appropriately in a shape that can be made.

  The link mechanism 170c is a mechanism for interlocking the second pressing members 151c and 151d of the first holding unit 150c with the cable cutting operation of the cutter unit 200. The basic configuration of the link mechanism 170c is the same as that of the link mechanism 170 of the drop cable recovery device 1 of the first embodiment described above, and detailed description thereof is omitted. Therefore, differences will be described below.

  As shown in FIG. 29, the tension coil spring 177c of the link mechanism 170c according to this modification is different in that one end is connected to the wire 179c and the end of the wire 179c is connected to the connecting portion 156c. .

  As a result, when the second pressing members 151c and 151d are in a fixed position, the tension of the tension coil spring 177c does not work. For this reason, the collection | recovery part 10c can hold | maintain the 2nd presser 151c, 151d stably in a fixed position. On the other hand, when starting the cutting operation, if the wire 179c is pulled downward beyond the length of the wire 179c, the tension of the tension coil spring 177c acts to press the drop cable C before the cutting operation of the cutter unit 200. be able to.

  The second holding unit 500c will be described with reference to FIG. The basic structure of the second holding unit 500c is the same as that of the second holding unit 500 shown in the first modification.

  The first difference between the second holding unit 500 and the second holding unit 500c is that the third presser 510 is disposed on the first surface 114 side of the gripping plate 110, whereas the third difference is that The presser 510c is a point provided between the first holding plate 110c and the second holding plate 110d. The second difference between the second holding unit 500 and the second holding unit 500c is that a lock mechanism for the lock member 560c for locking the third pressing member 510c is provided.

  Specifically, the lock member 560c mainly includes a lock pin 561c, a coil spring 562c, and a holding member 563c, as shown in FIGS. The lock member 560c is provided on the first surface 114c of the first grip plate 110c.

  As shown in FIG. 33, the holding member 563c is a U-shaped member formed by bending a plate. The holding member 563c fixes two flange-shaped end portions 565c to the first grip plate 110c. In the holding member 563c, a lock pin 561c is movably penetrated and disposed in a portion spaced from the first grip plate 110c located at the approximate center thereof.

  The lock pin 561c is a cylindrical bar member, and is in a through hole (not shown) of the first gripping plate 110c formed in a direction substantially orthogonal to the first surface 114c of the first gripping plate 110c. To penetrate. The lock pin 561c includes an operation ring 564c for hooking a finger at an end portion on the first surface 114c side that is separated from the first gripping plate 110c.

  The coil spring 562c is disposed between the holding member 563c and the first grip plate 110c. The coil spring 562c is fixed to a lock pin 561c that penetrates the holding member 563c. The coil spring 562c biases the lock pin 561c toward the second grip plate 110d. In addition, a hole portion 580c (see FIG. 36) that engages with the lock pin 561c is provided at a portion that contacts the end portion of the lock pin 561c of the second grip plate 110d.

  When such a lock member 560c is pulled in a direction away from the first gripping plate 110c, the gap between the second gripping plate 110d and the lock pin 561c is slightly larger than the thickness of the third pressing member 510c. It is formed between the ends. In addition, in the fixed position (non-cutting position), the 3rd pressing tool 510c is pinched | interposed into the lock pin 561c and the 2nd holding plate 110d (refer FIG. 35).

  Next, the holding operation of the drop cable C using the first holding unit 150c and the second holding unit 500c will be described in detail. FIG. 33 is an enlarged view showing a state where the lock pin 561c of the lock member 560c of the second holding unit 500c is in contact with the third pressing member 510c (non-locked state). FIG. 34 is an enlarged view showing a state where the lock member 560c of the second holding unit 500c is engaged with the hole 580c of the second gripping plate 110d. FIG. 35 is a diagram showing a positional relationship among the lock pin 561c, the third pressing member 510c, and the second gripping plate 110d in a fixed position (unlocked state). FIG. 36 is a diagram showing the positional relationship between the third pressing member 510c, the lock pin 561c, and the second gripping plate 110d that are in the clamping position after cutting the drop cable C (locked state). FIG. 37 is a diagram illustrating the holding of the drop cable C using the first holding unit 150c and the second holding unit 500c.

  Note that the operation of inserting the drop cable C into the groove 112 and the operation of cutting the drop cable C are the same as those of the drop cable recovery device 1 of the first embodiment, and thus detailed description thereof is omitted. Further, the basic holding operation of the first holding unit 150c and the second holding unit 500 is substantially the same as that of the first holding unit 150 and the second holding unit 500, and thus the first holding unit 150 and the second holding unit. Only characteristic parts different from 500 will be described.

  When the drop cable C is inserted into the groove 112, the recovery unit 10c proceeds to a cutting operation of the drop cable C. When the operation string 250 (see FIG. 2) is pulled, the collection unit 10c is driven by the link mechanism 170c before being cut by the cutter unit 200, and the two second pressing members 151c of the first holding unit 150c. , 151d rotate to pinch the drop cable C.

  The locking portion 520 c of the third pressing tool 510 c is pressed by a pressing member 540 c provided on the first operation arm 213 of the cutter unit 200. As a result, the third pressing member 510c rotates around the fixed shaft 40. When the first operating arm 213 is further rotated, the third pressing member 510c is also rotated in conjunction with this (FIG. 33). At this time, the distal end portion 530c of the third pressing tool 510c moves toward the groove portion 112.

  When the cutter unit 200 moves to the cutting position, the engagement with the lock pin 561c that has pressed the third presser 510c at the fixed position is released (see FIG. 34). At this time, the distal end portion 530 of the third presser 510 c clamps the drop cable C accommodated in the groove portion 112 from the side 119 side of the groove portion 112.

  Here, as shown in FIG. 37, the third pressing member 510c is disposed between the second pressing members 151c and 151d. And the 3rd presser 510c clamps the drop cable C clamped by two points with the 2nd 2nd pressers 151c and 151d between them. Accordingly, the drop cable C is sandwiched and fixed at three points of the two second pressing members 151c and 151d and the third pressing member 510c in the axial direction thereof.

  Thereafter, when the tension of the operation cord 250 is loosened, the cutter unit 200 returns from the cutting position to the non-cutting position (fixed position) by the restoring force of the torsion coil spring 240 (see FIG. 2).

  On the other hand, in the first holding portion 150c, the base end portion 136 of the first presser 131 that has started to rotate to the closed position (fixed position) is inserted into the recess 157d provided in the distal end portion 154d of the second presser 151d. It is engaged and fixed, and the drop cable C is continuously clamped.

  Further, as shown in FIG. 36, the second holding unit 500c immerses the tip of the lock pin 561c of the lock member 560c into the hole 580c of the second gripping plate 110d and cuts the third pressing member 510c as shown in FIG. Lock and restrict its rotation. Thereby, the drop cable C is continuously clamped between the third pressing member 510c and the second gripping plate 110d.

  The gripping part 100c having such a configuration cooperates with the second holding part 500c even when the drop cable C to be collected cannot obtain a sufficient holding force only with the first holding part 150c. It is possible to hold the drop cable C securely by pinching.

  Further, by providing the first holding part 150c and the second holding part 500c, the drop cable C can be safely grasped and recovered even when one holding part fails and does not move.

  Further, by providing the second holding portion 500c, for example, when collecting the drop cable F having no tension, as described above, the base end portion 136 of the first presser 131 and the second presser 151d Since the concave portion 157c is not engaged, the first holding portion 150c cannot be fixed in the holding position after the cutting operation and the drop cable F cannot be gripped. However, in the collection unit 10c to which the second holding unit 500c is added, the drop cable F can be held by the second holding unit 500c.

  Further, in the collection unit 10c, a removal prevention tool 130 and a second pressing tool 151d are provided on the second surface 116d side of the second gripping plate 110d. For this reason, the distance between the position where the drop cable C is pressed and the cutting position of the cutter unit 200 are close to each other. Thereby, for example, it is possible to prevent the drop cable C taken into the groove portion 112 by the removal preventing tool 130 from being bent before the cutter portion 200 and coming off the cutting position. That is, even when the drop cable C is inserted into the groove portion 112 through the drop prevention tool 130 provided on the second surface 116d side from any angle, the second pressing tool 151d holds the drop cable C. . And in the collection | recovery part 10c, the cutter part 200 and the 2nd pressing tool 151d are arrange | positioned closely. For this reason, the bending of the drop cable C is suppressed between the two members, and the drop cable C can be arranged substantially linearly along the fixed shaft 40. Thereby, the collection | recovery part 10c can cut | disconnect the drop cable C reliably in the position most suitable for cutting | disconnection.

Further, the second presser 151 c includes a knob 161. Thereby, in the collection | recovery operation | work of the drop cable C from the collection | recovery part 10c, the operator can return the 2nd holding | maintenance part 500c to a fixed position, without touching the 2nd pressing tool 151d by the side of the cutter part 200. FIG. For this reason, when an operator removes drop cable C after collection from collection part 10c, it can prevent getting injured by touching cutter part 200.
In addition, since the tip of the first holding plate 110c is cut and shortened, there is no step 113L, 113R that may cause the drop cable to be caught even when an unapplicable drop cable enters the cable guide 111. Easy to unplug cables.

  In addition, this invention is not limited to the above-mentioned embodiment and modification. For example, in the present embodiment and the modification, a drop cable (lead-in wire) is described as an example of the cable, but the drop cable collection device is applied to other cables having a predetermined diameter. Can do. Further, in this embodiment and the modification, an operation string is adopted as an operation member of the cutter unit. However, as long as it is configured by a single operation rod, has insulation, and can be reduced in weight, An operation member of a formula can also be applied. In the third modification, the tip end portion of the first gripping plate 110c is notched, but the first gripping plate 110c and the second gripping plate 110d may have the same shape. Of course, various modifications can be made without departing from the scope of the present invention.
