Moreover as shown in Figure 4, upper body 11 and lower case 12 is another end 29 of lower case 12 here in this embodiment, has a tape hole 67, passes this tape hole 67 and can insert a tape 66.Tape hole 67 is through holes, by this through hole connection opening 67A and opening 67B.By passing tape hole 67 in advance tapes 66 are installed, cutter 10 can hang on operator's neck or the hook etc. by means of tape 66, and this is convenient especially for eminence work.
Following is explanation about the parts that constitute upper body 11.Another end 32 of upper body 11 is connected with lower case 12 by the pivot 35 of pivotable member 13.In upper body 11, arrange the arm 14 that extends to an end 32 of upper body 11 from pivot 35.As shown in Figure 9, the other end 14A of arm 14 for example is fixed on the pivot 35 in the mode that freely swings that pivot 35 is used as axle with screw 14C.By unclamping screw 14C and changing the angle of arm 14, can critically regulate the height of top holding member 15 on the end 14B who is arranged on arm 14, destroyer 16 etc.
At the 14B place, an end of arm 14, top holding member 15 with wherein it with direction that pivot 35 parallels on can be free to slide the ground mode up and down and be provided with.Top holding member 15 comprises a pair of top holding element 71.And a pair of compression spring 72 (Fig. 6 and 7) is arranged between the rear surface of end 14B of arm 14 and upper body 11.
As shown in Figure 5, top holding member 15 has two top maintaining parts 71 that keep glass fibre part 37A by 2, and bottom holding member 18 also has two bottom maintaining parts 33 that keep glass fibre part 37A by 2.Thereby glass fibre part 37A can be fixed at 2 and locate, and can prevent thus glass fibre part 37A cutter 20 by between it so that move its position when providing indentation thereon, perhaps fixing glass pars fibrosa 37A more reliably.Therefore, the part that glass fibre part 37A can be provided with indentation from it ruptures reliably, and can obtain constant surface of riving reliably.
Figure 10 (A) is the cut-open view that is used for keeping glass fibre holding member partly to Figure 10 (C): Figure 10 (A) represents open mode; Figure 10 (B) represents closed condition; And Figure 10 (C) represents the wherein clamped state of glass fibre part.As shown in Figure 10 (A), top maintaining part 71 has rubber section 71A, and rubber section 71A is arranged on the surface of the support that is made of metal.Be arranged on two edges of rubber section 71A from the outstanding projection 71B in the below of the surface elevation of rubber section 71A.Such structure allows two the end 33Bs of the projection 71B of top maintaining part 71 in abutting connection with bottom maintaining part 33, as shown in Figure 10 (B), and make it possible to thus prevent that when not using cutter 10 when closing upper and lower housing 11 and 12, the rubber section 33A of the rubber section 71A of top maintaining part 71 and bottom maintaining part 33 contacts each other.Therefore, when upper and lower housing 11 and 12 was closed for a long time, upper and lower rubber section 71A and 33A can not damage owing to close adhesion each other.
When closing upper and lower housing 11 and 12, as shown in Figure 10 (C), the interval between the rubber section 33A of the rubber section 71A of top maintaining part 71 and bottom maintaining part 33 is adjusted to the diameter D less than glass fibre part 37A.Therefore, keep glass fibre part 37A reliably between the rubber section 71A that can be by glass fibre part 37A being inserted in top maintaining part 71 and the rubber section 33A of bottom maintaining part 33.
In this case, the direction of arranging span W (seeing Figure 10 (C)) with the pivot 35 shown in Fig. 5 with paralleling, and upper and lower holding member 15 and 18 can equally bear bed knife F on the whole span W of upper and lower maintaining part 71 and 33.Thereby, when a plurality of glass fibre part 37A are arranged between upper and lower maintaining part 71 and 33 with line sidewards as expression among Figure 10 (C), can equally be applied to bed knife on all glass fibre part 37A.
As shown in Figure 5, the destroyer 16 that disconnects glass fibre part by the expansion indentation is arranged on the center between each top maintaining part 71.Destroyer 16 is fixed on the end 14B of arm 14 in the mode of the recessed top surface in top maintaining part 71 of destroyer wherein 16.When closing upper and lower housing 11 and 12, destroyer 16 can compress the part of the indentation that comprises glass fibre part 37A, so that the expansion indentation is disconnected.Destroyer 16 comprises that a support that is made of metal and one for example are placed on its lip-deep rubber section.Can expand by destroyer 16 being compressed comprise the part of indentation with cutter 20 added indentations, so that disconnect glass fibre part 37A reliably at the part place that marks indentation with cutter 20, and the surface that can well be rived thus.
As shown in Fig. 5 and 6, upper and lower housing 11 and 12 directions of opening at them are pushed by an elastomeric element (housing spring) 73.Angle (open angle) θ that is formed by them when upper and lower housing 11 and 12 is opened is set to for example about 30 degree.Thereby, after finishing the work of riving, for example, utilize the snap-in force of housing spring 73 can easily open upper and lower housing 11 and 12 with a hand.Because upper and lower housing 11 and 12 snap-in forces by housing spring 73 can remain under the open mode, so can easily be installed in retainer on the retainer meshing part when riving work.And, after finishing the riving of glass fibre part 37A, can easily remove the retainer 63 that wherein keeps optical fiber 37 from cutter 10.
When the cleaning of considering each one for example with when changing, reasonable is to obtain about 90 open angles of spending that formed by upper body 11 and lower case 12 reliably.Cutter 10 is configured to, and with cancellation open angle is restricted to the adjustment of 30 degree by the knob 13A (Fig. 9) that removes pivotable member 13 from pivot 35, and obtains 90 degree or bigger open angles pivotly reliably between upper and lower housing 11 and 12.Be equal to or greater than 90 degree by upper body 11 and lower case 12 were pivoted, can easily carry out the cleaning of cutter 10.Moreover,, can easily be arranged on the cleaning and the replacing of near each one of pivotable member by opening upper and lower housing 11 and 12 with the open angle that is equal to or greater than 90 degree.
As shown in figs. 1 and 2, cutter 10 has one and is used for upper body 11 and lower case 12 are remained on lock 76 under the closed condition on a side 11A of upper body 11.Lock 76 has: locking press button 76A, and it can slide along a side 11A of upper body 11; With stop pin 76B (see figure 2), be connected on the locking press button 76A.
