The cover member of main body 1 is being connected on the master unit 7 near on the position of main body 1 one sides with preferably swaying.Usually the longitudinal axis that makes the axle of rotating shaft 9 be parallel to the cable end 5 that is positioned at main body 1 is very easily, but this is not necessary.Cover member 8 is arranged to such an extent that can rotate around the axis and is produced off-position (Fig. 2), is stacked in the open top of master unit 7 and shutoff device body 1 basically thus in this location component 8.The bias spring 10 that parts 7 and 8 is pressed into its deployed position (Fig. 3) can comprise that is positioned at 24, two the horizontal arms 25 and 26 with corresponding parts in extension of helical spring 24 respective opposite ends and the contact component 7 and 8 of pin helical spring on every side that form rotating shaft 9 and link 7 and 8.

The latch gear 11 that parts 7 and 8 is clamped in off-position comprises a bayonet lock lever 27, this lever is connected on the master unit 7 rotatably about an axis, laterally outwards extend from these parts 7, the top 29 of lever 27 is passed in device opening 30 on the cover member 8 an and surface of a pallet 31 engagement cover members 8 is arranged when in the closed position, prevent the opening movement of cover member 8, spring 32 or other elastic devices can act on the lever 27, with it around the shaft 33 to pin direction towards above-mentioned position contacting motion takes place.Lever top 29 is easy to externally near cover member 8, thus it can be in the opposite direction manually and make cover member 8 free opening movements thus.If desired, other forms of chain shot locking device also is suitable for.

Cutter box 12 is arranged in cover member 8 and comprises plate-like cutting knife 2.In illustrated concrete structure, in the one group of cutting knife 2 that carries by cutter box 12 three cutting knife dishes 34 are arranged, 35 and 36 and they and cylindrical shaft or sleeve 37 whole formation, cutting knife dish 34,35 are spaced laterally apart and each cutting knife has different diameters with sleeve 37 axial directions with 36, sleeve 37 is installed in rotation on the cutter box 12, makes under cutter box 12 installment states, and cutting knife 2 is the contact cable easily.Similarly, the rotating shaft parallel of sleeve 37 is in the rotating shaft of roller 19, and positioning pipe 14 is on a plane of passing between two rollers 19.

Under cutter box 12 installment states, less cutting knife dish 34 is usually located at positioned adjacent pipe 14, and the position that major diameter cutting knife dish 36 is positioned at away from positioning pipe 14.Any suitable device can be used for releasedly clamping cutter box 12 and cover member 8 assemblings.But, in schematic structure, connect like this between cutter box mouth and the cover member 8: make to allow certain relative motion.Like this, cutter box 12 can move into and shift out a resting position, and in this position, cutting knife 2 thrusts cable 6 to greatest extent.Best spring 38(Fig. 5) or other elastic devices act between cover member 8 and the cutter box 12, make cutter box 12 normally be clamped in resting position.

As mentioned above, preferably cutter box 12 removably is installed on the main body 1, can be arranged by different cutting knifes and change.In schematic structure, the end 39 of cutter box 12 has a slotted hole 40(Fig. 9), place the roller pin 9 that is attached on the main body 1 in the hole slidably.Any proper device can be used for clamping cutter box 12 releasedly, can not separate with roller pin 9.Comprise that in schematic structure limits a pin 41, this pin at one end 42 links to each other with cover member 8, and the other end 43 stretches into the opening 44 of cutter box 12.Cross-bar 45 laterally extends from pin end 43, and the setting of opening 44 makes bar 45 can not pass this hole, with respect to cutter box 12 a specific position of rotation is arranged unless sell 41.When pin 41 was positioned at this position of rotation, cutter box 12 can be crossed normal position at rest to the bottom, threw off pin 41 and can skid off roller pin 9.

Because cross-bar 45 contacts with cutter box 12 lower surfaces, cross-bar 45 is fixed the resting position of cutter box.If necessary, pin 41 can guarantee that the adjustment of bar 45 corresponding axial locations also changes the resting position of cutter box thus with being threaded on the cover cap 8.Other devices also can be used for this purpose.

Preferably cutting knife 2 is limited, and can not rotate with a direction with respect to cover member 8, and in schematic structure, this function obtains by an arrangement of clutch.This arrangement of clutch is worked in the time can not preventing that cutting knife 2 from rotating with above-mentioned direction automatically.The advantage of this sampling device is to adopt different dissections for the different materials that may run in cable 6.According to the structure of illustrating in Figure 10, arrangement of clutch comprises that one fitly is positioned at around the cutting knife sleeve 37 and is hooked in helical spring 46 on the cutting knife box body 1 by the arm 47 from the 46 1 end horizontal expansions of screw thread spring.Between helical spring 46 and sleeve 37, there is CONTACT WITH FRICTION to a certain degree.

Said apparatus makes arrangement of clutch corresponding to the direction that acts on driving torque on the cutting knife sleeve 37, that is: when cutting knife 2 during with a direction rotating shaft, 46 pairs of rotations of helical spring have minimum resistance, but, when cutting knife 2 backward rotation, reaction between sleeve 37 and the helical spring 46 causes helical spring 46 to embrace sleeve 37 more tightly and clamps sleeve 37 thus, and it can not be rotated.This clamping is engaged on the rotation of removing cutting knife 2 and discharges automatically during with above-mentioned first direction rotation when influence or at cutting knife 2.Clearly, other forms of clutch also can be used for above-mentioned purpose.

Cut cable retainer 18 is a lever form preferably, and as shown in Figure 6 and Figure 7, it is connected on the cover member 8 and therewith moves.Under main body 1 open configuration, the end 48 of lever 18 is stacked in the opening 49 that forms by main element 7 and wall 4 relative sidewalls 50, and cable end 5 can be placed in the opening 49, contacts with lever end 48 and the axial location of attached cable 6 thus.But, when main body 1 is closed, lever 18 is shown opening 49 and stoped cable 6 outside axial motions, its advantage thus is to allow the axial expansion of cable 6 when cutting operation also to avoid the end load that cable 6 is fractureed or influence the skinning operations regularity thus.

As shown in the figure, preferably have one second retainer to be used for operating position, on this position, second retainer is positioned on the opening 49 when main element 7 and 8 is closed.This second retainer can be one and be fixed on or whole and cover member 8 formation and in main body 1 off-position rather than be stacked in the plate 57 of opening 49 in deployed position.Plate 57 when main element is positioned at off-position and cable 6 axially align, but its inner surface is more outside from wall 50 than lever end 48 inner surfaces, that is: between check plate 57 and the wall 50 gap greater than gap between locking lever 18 and the wall 50.Therefore, plate 57 does not hinder the above-mentioned axial expansion of cable 6 basically, but it can contact the end of cable 6 when cutting operation.

When needs were positioned at cable end 5 in the main body 1, apparatus main body 1 was opened, and lever 20 is positioned at Fig. 4 position.Positioning pipe 14 is inserted in this end 5, runs into retainer 18 up to its end, and the location of these parts as shown in Figure 6.Then, lever 20 is put Fig. 5 position and is clamped cable 6, and cover member 8 is flapped toward the master unit 7 of main body 1 subsequently.Between this moving period, retainer 18 is automatically shifted to position shown in Figure 7.Similarly, maximum at least cutting knife dish 36 is bitten the outer surface of cable end 5.Continue to close and cause cutting blade dish 36 to thrust cable 6, and may also thrust by other cutting knife dishes 34 and 35, but because the elasticity of cutter box 12 is installed, cutter box 12 there are some to drop in the cover member 8.Under main body 1 buttoned-up status, chain shot 11 automatically keeps it to close.Then, the user holds pipe 14, rotates main body 1 with respect to cable 6, at this moment manages 14 as handle, main body 1 is by the another manual manipulation, lantern finger ring 51 can parts in parts 7 and 8 on, be convenient to aforesaid operations, that is, one of user holds positioning pipe 14, and another holds lantern finger ring 51.

When main body 1 was rotated with respect to pipe 14 and cable 6, each cutting knife dish 34,35 and 36 peripheries along cable end 5 moved and cut cable insulation.The degree of depth of each such otch can be by repeating corresponding main body 1 rotation and increasing, because reduced the resistance of cutter box 12 to its resting position or minimum down position gradually.Cutting knife 2 is preliminary elections, and therefore, at cutter box 12 minimum down positions, cutting knife dish 34,35 and 36 will be cut cable 6 desired depths.Under an example case, minimum cutting knife dish 34 will be cut external insulation layer 52(Figure 11 of cable 6), the metal screen layer that middle cutting knife dish 35 will pierce through between dielectric layers 52 and 54, and big cutter box 36 will sting through the core 55(of cable 6 promptly: plain conductor).

Then, lever 20 discharges, and makes the length of cable 6 can extract positioning pipe 14 out.This move automatically makes cable end 5 each otch peeling from three otch, because cutting knife 2 still is embedded in the cable 6 and therefore plays a part the peeling parts.

When cable 6 is extracted out fully, the length of exposure of one section heart yearn 55 is arranged at end place, one section length of exposure with terminal 56 inner insulating layers that separate 54, one section further with the length of exposure of terminal 56 metal screen layers that separate 53, as shown in figure 11.Different arrangements will be obtained by the use of different cutter assemblies.

When needed, cut cable check plate 57 can have an inserted link (not shown), and this inserted link is easy to enter and can drop to from the outside of main body 1 make at adjacent stop plate 5) device in the smear metal that may block remove.The opening of main body 1 is discharged smear metal, allows device perform the preparation of next step operation.

The said apparatus structure is quite simple and operation is very convenient.Its distinct advantages be this device can in an operation, finish a series of cuttings and do not need to resemble use similar have earlier each otch is adjusted respectively the device.

The spirit and scope that limit in not breaking away from appended claims book of the present invention, various conversion are revised and/or are increased and change the arrangement that can introduce said structure and parts.
