On.Here, axial protrusion 28,30 respectively from it is corresponding adjust control element 20,22 and set out extend across moving synchronously element 24
Until in the bending guide rail 102 of bending guide rail element 18.Therefore, at least two control element 20,22 is adjusted by means of axial convex
It portion 28,30 and moves synchronously element 24 and is connected in Motion Technology with bending guide rail element 18, particularly shape-ordinatedly
And/or force-fitting connect.
Axial coupling regime 26 includes the empty slot 36,38 of at least one slit-like, and the empty slot of the slit-like has at least
The main extension axis 42,44 extended basically perpendicular to the rotation axis 40 for moving synchronously element 24.The empty slot 36,38 of slit-like from
The fringe region being maximally spaced apart with the rotation axis 40 for moving synchronously element 24 for moving synchronously element 24 is transported towards synchronous
The direction of the rotation axis 40 of dynamic element 24 extends.In short, axial coupling regime 26 has the empty slot 36 of at least two slit-likes,
38, the empty slot has at least substantially similar configuration.In order to make at least two adjusting control elements 20,22 and move synchronously member
Part 24 connects, the cooperation of each one in axial protrusion 28,30 and the empty slot 36,38 of at least two slit-likes.Here, extremely
The empty slot 36,38 of few two slit-likes is arranged with being radially spaced.
Cutting line adjust unit 14 can the configuration based on the bending guide rail 102 of bending guide rail element 18 and based on to
The phase of few two adjusting control elements 20,22, particularly the axial protrusion 28,30 for adjusting control element 20,22 at least two
Interaction is configured to no spring.Here, axial protrusion 28,30 sticks on the inclined-plane 104 of bending guide rail 102, wherein as long as
The cutting line length of cutting line 16 is more than scheduled value, the power as caused by the rotation of wire type cutter device 10 by axial protrusion 28,
30 are pressed on the inclined-plane 104 of bending guide rail 102.In the case where being less than the scheduled cutting line length of cutting line 16, come from
At least two power for leading at least two adjusting control elements, 20,22 pendulum motion for adjusting control element 20,22 are greater than axis
The power on inclined-plane 104 for being pressed onto bending guide rail 102 to protrusion 28,30.From causing at least two adjusting control elements 20,22
The power of at least two adjusting 20,22 pendulum motions of control element can be by the centrifugation that acts on centrifugal force movement arm 96,98
Power generates.Since at least two adjust 20,22 pendulum motion of control element, axial protrusion 28,30 is transported inside bending guide rail 102
It is dynamic.Bending guide rail element 18 is released relative to the movement possibility of the shell 86 of wire type cutter device 10.Therefore, the coil of wire is cut
Axis 88 can also be moved relative to the shell 86 of wire type cutter device 10, and bending guide rail element 18 is arranged in institute without relative rotation
It states on cutting line spool.Shell 86 due to bending guide rail element 18 relative to wire type cutter device 10 moves, axial protrusion 28,
30 are guided along bending guide rail 102.Here, the bending guide rail 102 of bending guide rail element 18 constructs in this way, i.e., at least two adjust
Section control element 20,22 returns to original position, In with the ways and means movement having been known for those skilled in the art
In the original position, on the inclined-plane 104 for the bending guide rail 102 that axial protrusion 28,30 sticks on bending guide rail element 18 again,
And bending guide rail element 18 and thus cutting line spool 88 may relative to the movement of the shell 86 of wire type cutter device 10
Property is aborted.In addition, the bending guide rail 102 of bending guide rail element 18 constructs in this way, i.e., in bending guide rail element 18 and thus
When cutting line spool 88 is moved relative to the shell 86 of wire type cutter device 10, it can be got around at least from cutting line spool 88
The cutting line 16 of 100mm.
Can alternatively or additionally it consider, in order to support the swing of at least two adjusting control elements 20,22
Movement, cutting line, which adjusts unit 14, has at least one spring element 46,48.In short, it includes at least that cutting line, which adjusts unit 14,
Two spring elements 46,48, the spring element are arranged for spring force to be pre-applied at least two adjusting control elements 20,22
(spring element 46,48 is diagrammatically only shown in Fig. 5).At least two spring elements 46,48 are arranged in cutting line
On the supporting member 50,52 for adjusting unit 14, a difference at least two adjusting control elements 20,22 is swingably supported
On the supporting member.Here, at least two spring elements 46,48 are configured to helix torsion spring.However it is also contemplated that
, at least two spring elements 46,48 have other so that those skilled in the art is thought significant configuration and/or arrangement.
In addition, wire type cutter device 10 has at least one cutting line pilot unit 54.Cutting line pilot unit 54 has
(Fig. 2,4 and 5), the cutting line director element, which has, is parallel to rotation at least one cutting line director element 56,58,60,100
The longitudinal axis 62,64,66,68 of axis.Here, cutting line director element 56,58,60,100 is relative to longitudinal axis 62,64,
66,68 are rotationally symmetrically constructed.Therefore make to act on when it can be advantageous to be guided out in the shell 86 from wire type cutter device 10
Load on cutting line 16 keeps very little.Cutting line director element 56,58,60,100 is configured to pilot sleeve.Here, cutting
Line director element 56,58,60,100 rotatably supports, particularly can be rotated to support on the shell 86 of wire type cutter device 10
On.Cutting line pilot unit 54 include at least two cutting line director elements 56,58,60,100, the cutting line director element
It arranges with being radially staggered each other.In short, cutting line pilot unit 54 have at least four cutting line director elements 56,58,60,
100, the cutting line director element has at least substantially similar configuration.In four cutting line director elements 56,58,60,100
At least two be arranged in different circular rails around the rotation axis of wire type cutter device 10.Here, at least four cuttings
In four of line director element 56,58,60,100 longitudinal axial 62,64,66,68 at least two around wire type cutter device 10
Rotation axis be arranged in a common circular rail, and the four of at least four cutting line director elements 56,58,60,100
Two rotation axis around wire type cutter device 10 in a longitudinal axis 62,64,66,68 be arranged in one it is other common
Circular rail on.Here, the circular rail and the other circular rail have different diameters.Pass through cutting line director element
56,58,60,100 arrangement can make cutting line when cutting line 16 to be guided out from the shell 86 of wire type cutter device 10
16 load in two o'clock keeps minimum.It is cut here, on the one hand the point is one in cutting line spool 88 and wire type
The point arranged in transitional region between the shell 86 of device 10, and be on the other hand the shell of an online cutter device 10
