  Next, the procedure and operation of the protective tube mounting operation using the binding band gripping tip tool 1 will be described.

  FIG. 8 shows an operation of attaching the protective tube 120 to the electric wire 110 by the binding band gripping tip tool 1. Before entering the operation of FIG. 8, as shown in FIG. 7, the binding band 100 is previously held by the first movable portion 21 and the second movable portion 22 by the operator. In this state, the lock part 100 b of the binding band 100 is accommodated in the lock part accommodating part 21 a of the first movable part 21 in the right half and in the lock part accommodating part 22 a of the second movable part 22. ing. As shown in FIG. 7, the base part of the band part 100 a of the binding band 100 is accommodated in the band base accommodating part 21 d of the first movable part 21 and the left half of the second movable part 22. It is accommodated in the band root accommodating portion 22d. In this state, the tip S of the band portion 100a of the binding band 100 is not penetrated through the lock portion 100b and is in a free state.

  Next, in a state where the binding band 100 is gripped, the binding band gripping tip tool 1 is raised, and the first movable portion 21 and the second movable portion 22 are moved to the vicinity of the protective tube 120 covered with the electric wire 110. Let As shown in FIG. 8, the protective tube 120 has an opening 120a extending in the axial direction, and the electric wire 110 can be accommodated in the protective tube 120 by temporarily expanding the opening 120a. It has become. In order to securely attach the protective tube 120 to the electric wire 110, it is necessary to fix the protective tube 120 to the electric wire 110 through the binding band 100.

  In order to fix the protective tube 120 to the electric wire 110 by the binding band 100, first, the tip portion S of the band portion 100a of the binding band 100 is lifted to a position higher than the position of the protective tube 120, and then the tip portion of the band portion 100a. The vicinity of S is gripped by using an existing gripping tool 40 called “Yatsuko” and brought close to the first movable portion 21 and the second movable portion 22. And the front-end | tip part S of the band part 100a is entered into the band part introduction ports 21b and 22b, and the front-end | tip part S of the band part 100a is inserted in the lock | rock part 100b. That is, as shown in FIG. 5, the tip end S of the band portion 100a is inserted into the lock portion 100b by pushing the tip end S of the band portion 100a in the direction of the arrow F3 using the existing gripping tool 40. And the front-end | tip part S of the band part 100a penetrates the locking part 100b by pushing the front-end | tip part S of the band part 100a further in the arrow F3 direction using the existing gripping tool 40. Next, by pushing the band portion 100a further in the direction of arrow F3 using the existing gripping tool 40, the leading end S of the band portion 100a advances in the direction of arrow F4 and is movable through the band portion discharge ports 21c and 22c. It is discharged outside the portions 21 and 22.

  In a state in which the distal end S of the band part 100a is completely discharged from the band part discharge ports 21c and 22c, the first movable arm 15 and the second movable arm 16 are moved away from each other by the operation of the lever 19, The gripping of the binding band 100 by the binding band gripping tip tool 1 ends. Thereafter, the tip S of the band part 100a completely discharged from the band part discharge port 22c is pulled in the direction of arrow F4 by the existing gripping tool 40, and the protective tube 120 is attached to the electric wire 100 via the binding band 100. become.

  Here, as shown in FIG. 10, since the binding band 100 extends in a direction orthogonal to the opening 120a of the protective tube 120, the opening 120a is not greatly expanded. 110 is securely attached. That is, in the state in which the claw (not shown) of the lock part 100b and the groove M of the band part 100a are engaged, the band part 100a is opposite to the lock part 100b in the same manner as the ratchet mechanism. It becomes impossible to move in the direction (the direction opposite to the arrow F3 in FIG. 5). Thereby, in a state where the groove M of the band portion 100a and the lock portion 100b are engaged, the protective tube 120 is restrained by the binding band 100 so that the opening portion 120a is substantially minimized. Therefore, the protection tube 120 is prevented from being detached from the electric wire 110 through the opening 120 a due to restraint by tightening the binding band 100, and is securely attached to the electric wire 110.

  Thus, in the state where the binding band 100 is gripped by the first movable portion 21 and the second movable portion 22, the tip portion S of the band portion 100a is locked to the lock portion accommodating portion 21a via the band portion introduction ports 21b and 22b. , The leading end S of the band part 100a guided by the lock part 100b accommodated in the 21b and discharged through the band part discharge ports 21c and 22c is passed through the lock part 100b. 100b can be easily engaged from a distant position. Therefore, compared with the conventional indirect hot wire method using an insulating tape or a sheet clamp, it is possible to speed up the operation and reduce the cost. And in the indirect hot wire method using the binding band 100, since the work can be performed smoothly and reliably as described above, mental and physical fatigue during the work can be reduced.

  Moreover, since the band part introduction ports 21b and 22b are set to have a narrower regulation width in the thickness direction of the band part 100a as they approach the lock part accommodation parts 21a and 22b, the bands guided to the band introduction ports 21b and 22b. The tip portion S of the portion 100a can be easily guided to the lock portion 100b of the binding band 100, and the work efficiency can be increased. Furthermore, since the gripping tool body 10 can move the movable portions 21 and 22 via the lever 19 and the rods 17 and 18, the binding band 100 can be bound even from a position far away from the gripping tool body 10. .

  In this way, by using the binding band gripping tip tool 1, it is possible to easily engage the band portion 100a and the lock portion 100b of the binding band 100 from a position apart from each other without requiring skill. Therefore, even if it is the first work, anyone can work easily. In addition, since the work to be performed by the binding band 100 is not limited to any object to be fixed, the work can be applied to, for example, a complicated place or a narrow place, and a work in a small work space is possible. In addition, in the indirect hot wire method, bundling with the binding band 100 can be easily performed, so that the work menu of the indirect hot wire method can be increased, and the application range of work using the binding band 100 can be expanded.

  The embodiment of the present invention has been described in detail above, but the specific configuration is not limited to the above-described embodiment, and even if there is a design change or the like without departing from the gist of the present invention, It is included in this invention. For example, in this embodiment, the first movable portion 21 and the second movable portion 22 are formed with lock portion accommodating portions 21a and 22a, respectively, so that the binding band 100 is gripped with the same configuration from the left and right directions. However, as shown in FIG. 11, the lock part accommodating part 22a for accommodating the lock part 100b only in the second movable part 22, the band part introduction port 22b for guiding the tip part S of the band part, and the band part It is good also as a structure which forms the band part discharge port 22c for discharging | emitting the front-end | tip part, and grips the binding band 100 from the left-right direction with two members, the 1st movable part 21 and the 2nd movable part 22. FIG.

  The binding band 100 has a structure in which the band portion 100a is bound by engaging the groove M of the band portion 100a and the claw (not shown) of the lock portion 100b, but the band portion and the lock portion are engaged in the binding direction. If it is a structure, it is good also as a structure which uses another kind of binding band.
