Title: Insulating-stripping tool designed as a hand tool, cutting part for an insulation-stripping tool and method for stripping a cable

Description:
AREA OF TECHNOLOGY 
     The invention relates firstly to an insulation-stripping tool designed as a hand tool for stripping insulation from a cable, comprising a first insulation-stripping cutter for stripping the insulation transversely to a longitudinal direction of the cable and a second insulation-stripping cutter for stripping the insulation in the longitudinal direction of the cable. 
     The invention further relates to a cutting part for an insulation-stripping tool configured as a hand tool. 
     Furthermore, the invention relates to a method for stripping insulation from a cable using an insulation-stripping tool preferably configured as a hand tool, wherein the insulation-stripping tool comprises a first insulation-stripping cutter and a second insulation-stripping cutter. 
     PRIOR ART 
     For stripping and removing insulation from a cable, it is known to use insulation-stripping tools, which comprise at least one first insulation-stripping cutter for performing a separating cut in the insulation transversely to the longitudinal extension of the cable. In particular in difficult-to-access regions, for example, distributor boxes etc. there is a need to also cut into or cut open the section to be stripped of insulation in the longitudinal direction of extension. This facilitates the removal of the insulation section. For this purpose, known insulation-stripping tools have a second insulation-stripping cutter, which, if necessary, serves to perform a cutting-open of the insulation in the longitudinal direction of the cable. 
     In this connection, reference is made, for example, to DE 38 08 950 A1. Known from this is an insulation-stripping tool, which substantially consists of two half-shell-like jaws, which are pivotable about a common axis toward one another into a closed position. The insulation-stripping tool, which is configured overall as elongated, has respectively one first insulation-stripping cutter in the area of one end assigned to the inner surfaces of the half-shells pointing toward one another. A cable inserted between the half-shells is cut into by the first insulation-stripping cutter in the area of its insulation upon closure of the half-shells, wherein this cutting process is assisted in particular by a turning of the insulation-stripping tool about the longitudinal axis by approximately 180° to one side and to the other side. For separation of the insulation in the longitudinal direction, the cable is initially taken from the insulation-stripping tool and inserted again turned overall by 180 degrees perpendicular to the longitudinal extension, after which a second insulation-stripping cutter arranged in the area of the other end of the insulation-stripping tool can be used for cutting open the insulation in the longitudinal direction. 
     Another insulation-stripping tool is known from DE 44 11 028 C1. This is configured to be pliers-like, accordingly comprising two pliers legs, wherein two first insulation-stripping cutters pointing toward one another are provided at one free end of the pliers leg for stripping the insulation transversely to the longitudinal direction of the cable. For stripping the insulation in the longitudinal direction of the cable, the cable can remain in the pliers in the pliers closed position after carrying out the stripping transversely to the longitudinal direction of the cable. A second insulation-stripping cutter is actively brought into an active position by the user. For this purpose, a slider which can be actuated with the thumbs, for example, is provided which can bring the second insulation-stripping cutter about a geometric axis of rotation from a concealed position into a lowered position penetrating into the insulation. 
     SUMMARY OF THE INVENTION 
     With a view to the previously described prior art, an object of the invention is seen in further improving an insulation-stripping tool of the type in question in a favorable manner for handling. The object also consists in providing a cutting part, which enables a favorable handling of the hand tool. Furthermore, it is the object of the invention to provide a method, which enables a favorable stripping of the insulation from a cable in terms of handling. 
     A possible solution of the object according to a first inventive idea is given in an insulation-stripping tool in which the focus is on the fact that the first insulation-stripping cutter is mounted pivotably for movement between a cutting engagement position and a release position. 
     As a result of the proposed configuration, an insulation-stripping tool of the type in question is provided which allows favorable use in terms of handling. The first insulation-stripping cutter of the tool can, for example, for carrying out further work with the tool, be favorably pivoted into a position in which this first insulation-stripping cutter preferably does not penetrate or does not substantially penetrate in a cutting manner into the insulation of the cable inserted into the insulation-stripping tool. By this means, for example, in a possible tool closure position, which is used in the usual manner for stripping the insulation transversely to the longitudinal direction of the cable, a displacement of the cable in the longitudinal direction of the cable can be performed by pivoting the first insulation-stripping cutter into the release position. For example, after pivoting the first insulation-stripping cutter back into the cutting engagement position hereafter, a possible second cut can be made in the circumferential direction of the cable or alternatively a longitudinal cut for stripping the insulation in the longitudinal direction of the cable using the second insulation-stripping cutter. 
     With regard to the cutting part, a possible solution of the object according to a first inventive idea is given in which the focus is on the fact that a first insulation-stripping cutter and a second insulation-stripping cutter are formed on a pivoting body pivotable about a pivot axis, wherein the first insulation-stripping cutter is configured for a cut in the direction of the pivot axis and the second insulation-stripping cutter is configured for a cut transversely to the pivot axis. 
     Preferably in this case the insulation-stripping cutters are arranged offset in the circumferential direction on the pivoting body. Without such an offset, a turning of the cable alone about its longitudinal axis is certainly almost impossible when insulation-stripping cutters are inserted into the insulation of a cable. On the other hand, in certain cases of application, possibly when the insulation-stripping cutters are favorably matched in the transverse direction to the diameter of the cable and the thickness of the insulation, such a situation can be accepted. In this case, a T-shaped incision of the two insulation-stripping cutters then usually results if these, as it were, have grown together. 
     With the offset in the circumferential direction, this ultimately also results in a T-shaped cutting pattern but with a non-cut area between the cut in the longitudinal direction and the cut in the transverse direction of the cable. 
     As a result of the proposed configuration, an advantageous cutting part for an insulation-stripping tool is provided. The cutting part can be used both for stripping insulation from a cable transversely to a longitudinal direction of the cable and also for stripping the insulation in the longitudinal direction of the cable. To this end, the cutting part has two correspondingly configured and aligned insulation-stripping cutters, of which in each case, one can be pivoted into the respective cutting position or can be pivoted out from this for deactivation. Preferably both insulation-stripping cutters can be pivoted into the respective cutting position or can be pivoted out from this cutting position. In the case of a lack of offset of the insulation-stripping cutters on the pivoting body in the circumferential direction, the second insulation-stripping cutter is preferably configured to be so long in the circumferential direction of the pivoting body that, for example, with a pull on the cable, an incision is made with a further region of the insulation-stripping cutter, which initially had not yet been inserted into the insulation. 
     The geometric pivot axis of the cutting part comprising the first and the second insulation-stripping cutter preferably extends in a parallel plane to a cutting plane predefined by the first insulation-stripping cutter. The geometric pivot axis can also extend within this cutting plane. Furthermore, the cutting plane predefined by the second insulation-stripping cutter can be directed transversely to the geometric pivot axis of the cutting part. 
     The offset in the circumferential direction between the first and the second insulation-stripping cutter can, as is also preferred, be more than 45 degrees, in particular approximately 75 to 105 degrees, thus for example, approximately 90 degrees, furthermore optionally however also more than 90 degrees as far as 180 degrees or more. 
     One possible solution of the object in relation to the method according to a further inventive idea is given in which the focus is on the fact that the first insulation-stripping cutter is brought into engagement with the insulation of the cable and is brought from the cutting engagement position into its release position by pulling on the cable. 
     As a result of the configuration according to the invention, a method favorable for handling is obtained. The cable to be stripped of insulation can also preferably remain in the insulation-stripping tool after performing the cut performed in the circumferential direction of the cable using the first insulation-stripping cutter. Preferably the first insulation-stripping cutter is brought from the cutting engagement position into its release position merely by pulling on the cable, preferably while pulling out from or pulling through the insulation-stripping tool. The first insulation-stripping cutter is thus brought into a position substantially or completely outside the insulation circumference. 
     This displacement of the first insulation-stripping cutter from the cutting engagement position into its release position can, as is also preferred, be carried out as a result of pivoting the first insulation-stripping cutter about a geometric pivot axis. 
     The features of the previously described independent claims are important both in each case substantially for themselves and also in any combination with one another, wherein further features of an independent claim can be combined with the features of a further independent claim or with features of several independent claims, furthermore also with only individual features of one or more of the further independent claims. 
     Further features of the invention are also explained in the description of the figures, frequently in their preferred assignment to the subject matter of claim  1  and/or the further independent claim(s) or to features of further claims. They can, however, also be important in an assignment to only individual features of claim  1  and/or the further independent claims or the respective further claim or in each case independently. 
     The pivot axis, in particular geometric pivot axis, of the first insulation-stripping cutter can, as is also preferred, run transversely to the longitudinal direction of the cable. A pulling movement of the cable for pivoting the first insulation-stripping cutter from the cutting engagement position into the release position is accomplished in the usual manner in the longitudinal direction of the cable and thus transversely directed to the geometric pivot axis of the first insulation-stripping cutter, whereby as a result of the engagement of the first insulation-stripping cutter in the insulation of the cable, a pulling on the cable brings about a pivoting displacement of the first insulation-stripping cutter by entrainment as far as the release position. 
     The pivot axis of the first insulation-stripping cutter can furthermore be aligned so that this does not cut the cable. Accordingly it is preferred that the pivot axis of the first insulation-stripping cutter runs outside with reference to a cross-section through the cable inserted in the insulation-stripping tool and further preferably at a distance from the outer circumferential line of the insulation of the cable. Optionally the geometric pivot axis of the first insulation-stripping cutter can touch the insulation of the cable in such a cross-sectional view. 
     The first insulation-stripping cutter can be moved between the cutting engagement position and the release position merely by action of the insulation-stripping cutter itself. This action can be provided merely via the pulling movement on the cable. 
     In one possible embodiment, the first insulation-stripping cutter can have a rectilinearly stretched profile. This rectilinear profile can be directed parallel to the geometric pivot axis of the first insulation-stripping cutter, alternatively for example, enclosing an acute angle of a few angular degrees, for example, 2, 3 or 5 or more degrees to the geometric pivot axis. 
     The first insulation-stripping cutter can also have an arcuate profile for embracing a circumferential partial area of the cable, in particular the insulation. When considered in a view in which the geometric pivot axis is represented linearly, a concave arc profile of the insulation-stripping cutter can thus be given, preferably with a radius which remains the same throughout. This radius can, as is also preferred, be selected to be larger than the radius of a largest permissible cable radius in relation to the tool having the first insulation-stripping cutter. 
     The arcuate profile can furthermore also be composed of different radius portions over the extension length of the insulation-stripping cutter. In addition, in the sense of the invention, an arcuate profile is also obtained, for example, with an overall v-shaped insulation-stripping cutter, which is configured to be approximately notch-shaped in relation to the resulting cutting plane. 
     In particular in relation to the insulation-stripping tool, it can be provided that the first and second insulation-stripping cutters are pivotable about different pivot axes. These pivot axes, in particular the geometric pivot axes, of the two insulation-stripping cutters can, as is also preferred, be aligned in the same direction. Furthermore, in such an arrangement the first and second insulation-stripping cutters can be motion-coupled, so that a pivoting of the first insulation-stripping cutter from the cutting engagement position into the release position can at the same time bring about a pivoting of the second insulation-stripping cutter from the release position into the cutting engagement position. 
     This can also be achieved in a configuration in which the first and second insulation-stripping cutter are pivotable about the same pivot axis. In this case, the two insulation-stripping cutters can have separate pivoting bodies, which however enable a pivoting about the same pivot axis. 
     According to a preferred embodiment, the first and second insulation-stripping cutters are formed on the same pivoting body. By this means, a forced pivoting displacement of the second insulation-stripping cutter is preferably achieved with a corresponding pivoting displacement of the first insulation-stripping cutter. The first and second insulation-stripping cutter can in this case preferably be arranged offset with respect to one another in the circumferential direction of the pivoting body in relation to the geometric pivot axis, for example, enclosing an offset angle of approximately 90 degrees with respect to one another in relation to a cross-section transverse to the geometric pivot axis. By means of a corresponding pivoting of the first insulation-stripping cutter by, for example, approximately 90 degrees, the second insulation-stripping cutter can be transferred into its cutting engagement position. 
     In a possible embodiment the hand tool can be configured to be pliers-like, wherein a first insulation-stripping cutter is formed on working areas of both pliers legs. The working areas can be formed opposite to pliers handle regions in relation to an articulation axis of the pliers legs, about which articulation axis both pliers legs are preferably pivotable, wherein further preferably the pliers legs can also be connected to one another via a relevant articulation bolt. In particular, a first insulation-stripping cutter can be formed in the region of the free end of each working area, in particular in the region of the inner side of the working area pointing in the direction of the working area of the other pliers leg. Such hand tools are known as so-called insulation-stripping pliers. 
     The first insulation-stripping cutters of such insulation-stripping pliers with pliers legs according to the previously described designs can be arranged pivotably for possible pivoting of the same from a cutting engagement position into a release position, wherein further at least one first insulation-stripping cutter can be motion-coupled to a second insulation-stripping cutter, for displacement of the second insulation-stripping cutter from a release position into the relevant cutting engagement position. Further, such insulation-stripping pliers can thus have a pivoting body in a working area with a first insulation-stripping cutter and a second insulation-stripping cutter arranged offset in the circumferential direction. A pivoting body can be provided in the opposite working area, which merely bears a first insulation-stripping cutter. 
     As a result of this configuration, such insulation-stripping pliers can be used both for stripping a cable insulation transversely to the longitudinal direction of the cable and also for stripping the insulation in the longitudinal direction of the cable. 
     Fundamentally, the cutting depth of the first and/or second insulation-stripping cutter in the insulation is preferably adapted to the thickness of the insulation cladding. The braids, wires, or cores to be exposed by the insulation stripping are not damaged by the cuts using the first and/or second insulation-stripping cutter. 
     The hand tool can also comprise two hollow-body partial shells, which are arranged pivotably about a common pivot axis, wherein a first insulation-stripping cutter is formed on the hollow-body partial shell. In this hand tool configured in such a manner, this first insulation-stripping cutter can also be designed according to the previously described explanations, namely preferably mounted pivotably about a geometric pivot axis from a cutting engagement position into a release position and back. 
     Furthermore both hollow-body partial shells can have such a first insulation-stripping cutter. Furthermore, a second insulation-stripping cutter preferably motion-coupled at least to a first insulation-stripping cutter can be provided in one of the hollow-body partial shells, wherein in this regard an arrangement of the first and second insulation-stripping cutter on a common pivoting body can be provided. 
     Furthermore, the hollow-body partial shells can form a receiving cavity for the cable. This receiving cavity is obtained in particular in a closed position of the hollow-body partial shells. The cable to be insulated can be inserted in this receiving cavity, optionally furthermore passing right through the receiving cavity entirely, in such a manner that the cable can emerge from this on both sides at the end of the receiving cavity. 
     The first and the second insulation-stripping cutter can be arranged so that they are assigned to the same receiving cavity, so that the cable lying in this receiving cavity can lie and remain in this receiving cavity both for cutting into the insulation in the circumferential direction and also for stripping the insulation in the longitudinal direction of the cable. 
     The previously described features prove to be particularly favorable with regard to the method. The cable inserted in the hand tool, for example, into the receiving cavity or between the working areas of the pliers legs is grasped in a first method step by the preferably opposite first insulation-stripping cutters of the two working areas or of the two hollow-body partial shells, this while cutting into the insulation of the cable. As a result of turning the cable about the longitudinal axis, a stripping of the insulation in the circumferential direction can be achieved, whereafter a pivoting displacement of the first insulation-stripping cutter into the release position is achieved merely by pulling on the cable while maintaining the closed position of the hand tool, preferably accompanied by pivoting of the second insulation-stripping cutter into the cutting engagement position. In this position, this second insulation-stripping cutter digs into the insulation cladding of the cable in the manner of a plough in the neighborhood of the circumferential dividing cut, wherein the cable is displaced from the hand tool or through this while maintaining the pulling movement. In the course of this movement resulting in the longitudinal direction of the cable, the second insulation-stripping cutter cuts into the insulation in the longitudinal direction of the cable, for example, in the manner of a plough. This second method step is preferably maintained as far as the free end of the cable portion pulled through the hand tool. 
     When the tensile loading on the first insulation-stripping cutter ceases, in particular after the cable has been pulled completely through the hand tool, the first insulation-stripping cutter and via this or at the same time as this, the second insulation-stripping cutter can be restored into the base position, which base position corresponds to the cutting engagement position of the first insulation-stripping cutter and the release position of the second insulation-stripping cutter. This restoring can be achieved, for example, as a result of a correspondingly acting spring force. 
     The ranges or value ranges or multiple ranges given hereinbefore and hereinafter also include with regard to the disclosure all the intermediate values, in particular in 1/10 steps of the respective dimension, optionally therefore also dimensionless. For example, the specification up to 15 degrees also includes the disclosure up to 14.9 degrees, up to 14.8 degrees etc., the specification more than 45 degrees also includes the disclosure of more than 45.1 degrees, more than 45.2 degrees, etc. This disclosure can serve, on the one hand, for delimiting a said range limit from below and/or above, alternatively or additionally however for the disclosure of one or more singular values from the respective specified range.

     DESCRIPTION OF THE EMBODIMENTS 
     Shown and described, initially with reference to  FIG. 1 , is a first embodiment of a pliers-like tool  1  in the form of a cable cutter, which can also be used at the same time as insulation-stripping tool  2 , wherein the tool  1  is provided with a first insulation-stripping cutter  14  for stripping of an insulation  58  of a cable  39  transversely to the longitudinal direction of the cable  1  and with a second insulation-stripping cutter  62  for stripping in the longitudinal direction of the cable  1 . In particular, the first insulation-stripping cutter  14  is pivotably mounted. 
     The tool  1  forms at one end an insulation-stripping tool  2  and at the other end a cable cutter  2 ′ and in this embodiment initially and substantially comprises two pliers legs  4  and  5 , which are pivotably interconnected in a scissors articulation  3 . The resulting geometric pivot axis x in the scissors articulation  3  extends substantially perpendicular to a longitudinal extension of the pliers legs  4 ,  5 . 
     Formed on one side of the scissors articulation  3  (with reference to the longitudinal extension of the pliers legs  4 ,  5 ) on each pliers leg  4 ,  5  is a functional jaw part  6 ,  7 , here in for the form of a cable cutter in each case. In the cutting open position according to  FIGS. 1 to 4 , a cutting mouth  8  is obtained between these functional jaw parts  6  and  7 . 
     The cable cutters can be suitable for moving over one another in a scissors-like manner for cutting through a cable inserted in the cutting mouth  8 . 
     Facing away from the functional jaw parts  6  and  7  the pliers legs  4  and  5  form handle regions  9  and  10  on the other side of the scissors articulation bolt  3 . 
     When viewed in longitudinal extension of the pliers legs  4 ,  5 , a length b of the respective handle region  9 ,  10  is obtained, which can correspond to a multiple of the length a of the functional jaw parts  6 ,  7  also starting from the pivot axis x. In the depicted exemplary embodiment, the length b of the handle regions  9 ,  10  in the functional jaw part usage position corresponds to approximately 5 to 7 times, further approximately 6 times the cutter length a. 
     In the region of the free ends  11  of each handle region  9 ,  10 , as is also shown in the depicted exemplary embodiment, pivoting bodies  12 ,  13  assigned to each handle region  9 ,  10  can be provided with insulation-stripping cutters  14 . By using these first insulation-stripping cutters  14 , this tool  1  can be used as insulation-stripping tool  2 . 
     The hand tool  1  of the embodiment according to  FIGS. 1 to 28  can accordingly be used as desired in each case at the ends of the pliers legs  4 ,  5  as a cable cutter  2 ′ or as an insulation-stripping tool  2 . 
     Each handle region  9 ,  10  can initially comprise a handle shell  15 ,  16  consisting of a hard plastic, for example. 
     Furthermore, each pliers leg  4 ,  5  can also have a longitudinal division. In this case, a leg partial region  17  is arranged firmly inside the associated handle shell  15  or  16  whereas the second leg partial region  18  carrying the associated functional jaw part  6  or  7  can be displaced slidably relative to the first leg partial region  17 . This sliding displaceability is directed in longitudinal extension of the pliers legs  4 ,  5 . A telescopability of the respective pliers leg  4 ,  5  is the longitudinal extension of the leg can thus be obtained, wherein a T-guide or the like can be given in this respect. 
     The second leg partial regions  18  are preferably connected to one another via the scissors articulation  3 , so that a telescopic lengthening or shortening of one pliers leg at the same time brings about a corresponding length change of the other pliers leg in the same manner. 
     Furthermore, a possible relative displacement of the functional jaw parts  6  and  7  formed on the second leg partial regions  18  relative to the handle shells  15  and  16  can thus be obtained so that the functional jaw parts  6  and  7  can be displaced from a protruding position according to  FIGS. 1 to 15 , which also corresponds to the usual usage position of the functional jaw parts  6  and  7 , for example, for cutting through a cable or the like, into a retracted position in which the functional jaw parts  6  and  7  are moved substantially completely into a concealed position, substantially embraced by the handle shells  15  and  16 . 
     Both the protruding position and also the retracted position of the functional jaw parts  6  and  7  can, as is also preferred, be secured by locking. For this purpose, a button  19 , which is displaceable substantially in the direction of the pivot axis x, can be further provided on the housing outer side of one of the handle shells  15  and  16 , on which button a latching pin  20  projecting into the shell interior can be formed on the underside. This latching pin  20  can dip into a longitudinal slot  21  of the associated second leg partial region  18 , which can form a latching opening  22  enlarged with respect to the slot width at the ends in each case. 
     The latching openings  22  can be adapted according to the diagrams circumferentially to the cross-sectional shape of the latching pin  20 . 
     For cancelling a latching position, the latching pin is displaceable in alignment of the pivot axis x preferably against the restoring force of a spring  23  acting on the latching pin  20  into a position in which a waist-like tapered portion  24  of the latching pin  20 , which is adapted to the width of the longitudinal slot  21 , allows a displacement of the latching pin  20  along the longitudinal slot  21  in the direction of the other latching opening  22 . 
     The latching position found, as is also preferred, can be found automatically as a result of the restoring force of the spring  23 . 
     As can be seen, for example, from the diagram in  FIG. 4 , the second leg partial region  18  also comprising the longitudinal slot  21  with the latching openings  22  can have guide projections  25  on its inner side, facing the second leg partial region  18  of the other pliers leg, which in particular in the course of a tool closing movement can dip into corresponding recesses  26  of the other second leg partial region  18  possibly positively. 
     The telescopically displaceable second leg partial regions  18  with respect to the first leg partial regions  17  can be loaded in the telescoping direction via a further spring  27 , in particular in the form of a cylinder compression spring. This spring  27 , as is also shown, can be provided in the second leg partial region  18 , which also comprises the longitudinal slot  21  with the latching openings  22 . 
     Via the connection to the scissors articulation  3 , the restoring force of the spring  27  also acts on the second leg partial region  18  of the other pliers leg. 
     Via the spring  27  the functional jaw parts  6  and  7  are loaded in the direction of their protruding position. Accordingly, this results in a back-displacement of the same into the retracted position after cancelling the locking against the restoring force of the spring  27 . This must be overcome accordingly. 
     Another projection  28 , which projects over the dividing plane E between the pliers legs  4  and  5  or between the handle shells  15  and  16 , is formed on the pliers leg  4 . In the tool closure position, for example, according to  FIGS. 10 and 11 , this is accommodated in a recess  26  in the region of the handle shell  16  of the other pliers leg  5 . This projection  28  can be used for locking the tool  1  in the tool closure position, which at the same time also corresponds to the functional jaw part closure position. For this purpose, a, for example, thumb-actuatable slider can be provided on the pliers leg  5  comprising the recesses  29  on the outside of the relevant handle shell  16 , which with a locking projection  31  that is slidingly displaceable in the direction of the recess  29 , can retracted into a locking groove  32  formed on the projection  28 . The locking groove  31  is in this case directed transversely to the opening or closing direction of the pliers legs  4  and  5 . 
     In the tool closed position, the inner surfaces facing one another or the circumferential faces of the pliers legs  4 ,  5  facing one another, in particular the handle shells  15  and  16 , abut against one another (compare  FIG. 17 ). 
     Another spring  33  which substantially surrounds the scissors articulation bolt in the scissors articulation  3  can act on the pliers legs  4  and  5  in such a manner that these are loaded tendentially into an open position by the spring  33  according to the diagrams  3  and  4 , for example. 
     The displacement of the pliers legs  4  and  5  for example into a cutting position of the functional jaw parts  6  and  7  configured as cable cutters or into a tool closure position takes place accordingly contrary to the force of the spring  33 . 
     A further possible locking of the pliers legs  4  and  5  with respect to one another can be made possible by a fixing part  34  mounted pivotably parallel to the pivot axis x, which part can be brought outside a handle shell  15  with a side arm  35 ?? and a locking projection  36  provided at the end of the side arm behind a locking shoulder  37  in the region of the other handle shell  16 . 
     In order to use the hand tool  1  as an insulation-stripping tool  2 , the functional jaw parts  6  and  7  should preferably be moved into their retracted position. In order to prevent use of the insulation-stripping tools when the functional jaw parts  6  and  7  remain in the protruding position, a locking projection  38  can be provided, which in the functional-jaw-part protruding position projects into the dividing plane E in a hindering manner such that a movement of the pliers legs  4  and  5  into the contact position—tool closure position—is prevented. This situation is shown in a simplified manner in  FIGS. 13 and 13   a.    
     In the diagrams the locking projection  38  is aligned substantially vertically. This corresponds to the position of the locking projection  38  in the functional-jaw-part protruding position. The facing front faces of the handle shells  15  and  16  cannot come into their contact position as a result of the rising locking projection  38 . However, this contact position is necessary for the correct use of the pivoting bodies  12  and  13  comprising the first insulation-stripping cutters  14  for stripping the insulation from the cable  39 . 
     In this position, the locking projection  38  can also engage in a receiving cavity  45  in such a manner that a cable  39  to be stripped of insulation can be prevented from being introduced into the tool  1  through this receiving cavity  45  for carrying out the insulation-stripping process. 
     In the locking position, for example, according to  FIGS. 11 and 13 , a gap S is obtained in particular in the region of the free ends  11  as a result of the locking projection  38  pivoted in a perturbing manner into the dividing plane E. 
     The closure position is required for correct insulation stripping of a cable  39 , which can only be achieved in the functional-jaw-part retracted position. 
     With retraction of the functional jaw parts  6  and  7 , a pivoting displacement of the locking projection  38  is brought about via a control side arm  40  and a control cam  41  formed in this side arm. This locking projection sits with a control cam  42  in the control cam  41  and is pivotable about an axis  43  fixed in the associated handle shell  16  or the associated pliers leg  5 . The relevant geometric axis is aligned transversely to the pivot axis x of the pliers legs  4  and  5 . 
       FIGS. 19 and 19   a  show the pivoting position of the locking projection  38  after displacement of the functional jaw parts  6  and  7  into the retracted position. As can be seen, a pivoting displacement is achieved here via the control cam  41  which allows abutment of the front faces of the handle shells  15  and  16  facing one another or the pliers legs  4  and  5 . In this position, the locking projection  38  can also be pivoted out of the receiving cavity  45 . 
     With displacement of the functional jaw parts  6  and  7  back into their protruding position, in particular the control side arm  40  can be displaced back into its base position, for example, under spring loading, this being accomplished while raising the locking projection  38  via the control cam  41 . 
     The pivoting bodies  12  and  13  can, as is also shown, each be held pivotably on a block-like insert  44 . These inserts  44  can each be fastened in the region of the free ends  11  on the inside of the handle shells  15  and  16 , wherein further the inserts  44  in the contact position, which corresponds to the tool closure position, can form a receiving cavity  45 . The receiving cavity  45  extends substantially in the direction of longitudinal extension of the pliers legs  4 ,  5  or in the direction of longitudinal extension of the tool  1  overall. 
     Furthermore the receiving cavity  45  extends over a partial region of the handle regions  9 ,  10 , which can correspond to approximately a quarter to a third of the total length of the pliers legs  4 ,  5 . 
     The previously described projection  28  can be formed on one of the inserts  44  and the relevant recess  29  on the opposite insert  44 . 
     The pivoting bodies  12  and  13  can each be arranged at the end of the inserts  44 , assigned to the free end  11 , this further preferably in the region of a notching  47  of the inserts  44 . In this step-like notching the pivoting bodies  12  and  13  find a guide which allows a pivoting of the pivoting bodies  12  and  13  about a pivot axis y. This guide can, as is also preferred, be substantially a base-side guide. A top-side guide of the pivoting bodies  12 ,  13  can be achieved by tabs  48 , which can be fastened onto the inserts  44 . 
     The pivot axis y of the pivoting bodies  12  and  13  preferably extends in alignment of the pivot axis x in the region of the scissors articulation  3 . 
     Preferably the first insulation-stripping cutters  14  facing one another in a base position also extend in the direction of extension of the pivot axis y. These are fixed on the circumference of the respective pivoting body  12 ,  13  on these. 
     The first insulation-stripping cutters  14  can, as shown, have a rectilinear cutting edge  49  running parallel to the pivot axis y but alternatively also, as is further shown in  FIGS. 33 and 34 , for example, an arcuate profile for embracing a circumferential partial region of the cable  39  or also a V-shaped notch-like profile. 
     The handle regions  9  and  10  can comprise with regard to their longitudinal extension a first longitudinal portion  50  and a second longitudinal portion  51 , wherein the second longitudinal portion  51  is assigned to the free end  11 . As can be seen in particular from the longitudinal sectional view in  FIG. 9 , a parallel displacement of the longitudinal portions  50  and  51  with respect to one another can be obtained, wherein the two longitudinal sections  50  and  51  substantially each run in longitudinal extension of the pliers legs  4  and  5 . 
     The degree of offset of the longitudinal portions  50  and  51  in the direction of the pivot axis x can be adapted to a largest cable diameter usually permissible for this tool  1 . 
     The two longitudinal portions  50  and  51  go over into one another in a region of curvature  52 . An opening  53  is provided in this region of curvature  52 . This forms the opening of the receiving cavity  45  in the direction of the first longitudinal portion  50  while a further opening  55  is provided rearward of the handle shells  15  and  16  in the region of a relevant front wall  54 . Accordingly, an opening on both sides of the receiving cavity  45  when viewed in longitudinal extension is obtained. 
     The pivoting bodies  12  and  13  can substantially be arranged in a region between the receiving cavity formed by the inserts  44  and the opening  55  on the front wall side. 
     Further openings  56  can be provided below the opening  55  in the front wall  54 , assigned to rigid insulation-stripping blades  57  fastened on the inserts  44 , in particular for stripping the insulation from cores. 
     For stripping the insulation from a cable  39  this is inserted into a receiving cavity  45  (see, for example,  FIGS. 21 and 22 ). An end optionally guided through the receiving cavity  45  or a cable portion, after passing through the opening  53 , can rest on the facing surface of the pliers legs  4  and  5 , for which the handle shells  15  or  16  can optionally have a bead-like recess running in the longitudinal direction. 
     With closure of the pliers legs  4  and  5 , wherein a changed lever ratio is established in the retracted position of the cable cutters  6  and  7 , as a result of a shortening of the length b between the pivot axis x and the free end  11  as a result of the telescoping, the first insulation-stripping cutters  14  cut into the insulation  58  in a secant-like manner. This incision can be accomplished as a result of the arrangement of two first insulation-stripping cutters  14  diametrically opposite one another. 
     By turning in the direction of the arrow c of the cable  39 , a stripping of the insulation  58  can be achieved transversely to the longitudinal direction of the cable  1  and therefore in the circumferential direction. 
     In particular with longer portions to be stripped of insulation, it proves to be favorable to also strip the portion to be stripped in the longitudinal direction of the cable  1 . This is accomplished in the proposed insulation-stripping tool  2  in a manner favorable for handling after carrying out the stripping in the circumferential direction by pulling on the cable  39  in direction d. 
     As a result of this pulling, the first insulation-stripping cutters  14  are pivoted from the cutting engagement position (compare  FIG. 23 ) into a release position according to  FIG. 24  as a result of the pivotable mounting of the pivoting bodies  12  and  13 , wherein the pivot axis y of the pivoting bodies  12  and  13  runs outside and at a distance from the insulating cladding. 
     The pivoting displacement of the first insulation-stripping cutters  14  can, as is also preferred, be accomplished merely by acting on the first insulation-stripping cutters  14  via the cable  39  or the insulation  58  in the course of the loading on the cable  39  in the direction of tension. 
     Furthermore, this pivoting displacement of the first insulation-stripping cutters  14  about their pivot axis y can be accomplished against the force of a restoring spring  59  which urges the pivoting bodies  12  and  13  into their base position. This base position is preferably stop-limited. For this purpose, the pivoting bodies  12  and  13  have a stop shoulder  60  diametrically opposite the first insulation-stripping cutters  14  in relation to the cross-section according to  FIG. 23 , which in the base position according to  FIG. 23  can come up against a stop surface  61  in the handle region  9  or  10 . 
     With pivoting of the first insulation-stripping cutters  11  into the release position, a second insulation-stripping cutter  62  is preferably displaced into its cutting engagement position. In this cutting engagement position the second insulation-stripping cutter  62  dips into the insulation  58  of the cable  39 . 
     In this case, the second insulation-stripping cutter can be arranged on one of the pivoting bodies, here preferably the pivoting body  13 , according to the exemplary embodiment shown in  FIGS. 1 to 28 , as is further also shown in  FIGS. 31 and 32 . Thus, in this embodiment, this second insulation-stripping cutter  32  is pivotable about the same pivot axis y. 
     The second insulation-stripping cutter  62  can in this case, when viewed in the circumferential direction of the relevant pivoting body  13 , be arranged circumferentially offset to the first insulation-stripping cutter  14 . A pivoting of the pivoting body by approximately 90 degrees results in a change of the first insulation-stripping cutter into a release position and a change of the second insulation-stripping cutter  62  from its release position into the cutting engagement position. 
     In order to ensure a secure hold of the first insulation-stripping cutters  14  in the course of a radial insulation stripping, these are in particular arranged in relation to their cutting edges  49  cutting into the insulation  58  with reference to the direction of tension d at a distance f behind the pivot axis y (compare  FIGS. 29 and 31 ). 
     Whereas the first insulation-stripping cutter  14  or its cutting edge  49  extends in a plane directed in the direction of the pivot axis y, the cutting edge  63  of the second insulation-stripping cutter  62  can run approximately in a sickle shape in a plane transverse to the cutting plane of the first insulation-stripping cutter  14  so that as a result of the tensile loading on the cable  39 , a digging of the second insulation-stripping cutter  62  into the insulation  58  can be achieved. 
     The cutting engagement position of the second insulation-stripping cutter  62  or the release position of the first insulation-stripping cutter  14  can also be stop-limited. For example, as is also shown, the first insulation-stripping cutter  14  can enter in the handle region  9 ,  10  against a correspondingly aligned second stop surface  61  (compare, for example,  FIG. 24 ). 
     Alternatively to the arrangement of the first and second insulation-stripping cutter on a common pivoting body, according to the diagram in  FIG. 29 , each insulation-stripping cutter can also be assigned a relevant pivoting body. Thus, for example, the first insulation-stripping cutter  14  can be fastened to a separate pivoting body  13  while the second insulation-stripping cutter  62  can be formed on a second pivoting body  13 ′. The two pivoting bodies  13  and  13 ′ can also be motion-coupled via a rigid connection  65 , so that each pivoting movement of one pivoting body  13  or  13 ′ results in a corresponding pivoting movement of the further pivoting body  13 ′ or  13 . 
     In this case, accordingly two geometric pivot axes y and y′ are obtained for the two insulation-stripping cutters  14  and  62 , which pivot axes y and y′ can run in the same direction. 
     As a result of an insulation-stripping tool  2  configured in such a manner or a tool  1  having such an insulation-stripping tool  2 , a cutting pattern of the cable  39  according to  FIG. 27  can be established. In the area of its insulation, the cable  39  has a circumferential cut  66  caused by the first insulation-stripping cutters  14  and a longitudinal cut  67  running in the longitudinal direction of the cable  1 , caused by the second insulation-stripping cutter  62 . 
     The longitudinal cut  67  can be carried out continuously as far as the free end of the cable  39 . Facing the circumferential section  66 , a connecting web  68  having a length of, for example, 0.5 as far as, for example, 2 mm can be obtained, which tears open when peeling away the insulation section. 
       FIGS. 35 to 49  show another embodiment of a tool  1 . This also offers on one side of the scissors articulation  3  the possibility of the tool  1  for pliers-like cutting actuation, further for example, for use as cable cutter  2 ′ and on the other side of the scissors articulation  3 , for use as insulation-stripping tool  2 . 
     In this embodiment also the functional jaw parts  6  and  7 , here in the manner of cable cutters, are moved about the pivot axis x during usual use of the tool  1  with pliers legs  4  and  5  covered with handle shells  15  and  16 . A leg spring  33  provided here in the region of the scissors articulation  3  brings about a spring loading in the direction of a cutting mouth open position according to the diagrams in  FIGS. 35, 36 and 38 to 40 . 
     In the region of the handle-side free ends of the pliers legs  4  and  5 , in this embodiment also to form an insulation-stripping tool  2 , pivoting bodies  12  and  13  with first insulation-stripping cutters  14  and a second insulation-stripping cutter  62  are provided substantially according to the previously described exemplary embodiment in an offset second longitudinal section  51 . 
     In this case, the pliers leg  5  is formed in one piece and preferably of the same materials as the functional jaw part  7 , wherein further this pliers leg  5  is also formed in one piece relative to a leg portion facing the scissors articulation  3  and a leg portion assigned to the free handle region. 
     The further pliers leg  4  on the other hand is preferably formed in two parts, in this case substantially forming a pliers partial leg  71  assigned to the scissors articulation  3  and formed in one piece with the relevant functional jaw part  6  and a pliers leg  72  on the side of the handle area. 
     The two pliers partial legs  71  and  72  can, as is also preferred, be connected to one another via a pivot bolt  73 , whose geometric pivot axis v is preferably aligned parallel to the pivot axis x in the scissors articulation  3 . 
     Further the pliers partial leg  71  preferably extends on both sides of the pivot bolt  73 , wherein on the one side of the pivot bolt  73  the pliers partial leg  71  goes over into the functional jaw part  6  in the region of the scissors articulation  3  and on the other side of the pivot bolt  73  this forms a free side arm with an end-side and open-edged first blocking recess  74 . 
     The first blocking recess  75  formed in a basic outline, for example, according to  FIG. 38  in a step shape serves to cooperate with a first blocking projection  75 , which is articulated pivotably to the pliers partial leg  72  on the side of the handle region. The relevant geometric pivot axis w extends preferably parallel to the alignment of the pivot axis v or to the pivot axis x of the scissors articulation  3 . 
     The first blocking projection  75  can be formed in the manner of a pivotable bolt, which is pivotable from a latching position to the first blocking recess  74  into a release position and back deliberately by the user. For this purpose, a rotating handle  76  can be arranged at one free end of an axial body, which is connected nonrotatably to the first blocking projection  75  and which centrally receives the geometric axis of rotation w and passes through the pliers partial leg  72 , which handle is exposed and can be gripper on the wall outer side of the handle shell  15  completely overlaying the pliers leg  4 . 
     Furthermore, the first blocking projection  75  is spring-loaded in the direction of the first blocking recess of the pliers partial leg  71  on the scissors articulation side and thus in the direction of the latching and blocking position. For this purpose, according to the depicted embodiment a spring  77  in the manner of a leaf spring can be provided, which is supported on a leg-side extension  78  (compare, for example,  FIG. 36 ). 
     In the blocking position shown in  FIGS. 35, 36 and 38 to 44 , in which the first blocking projection  75  engages in the blocking recess  74  of the pliers partial leg  71  on the side of the handle region, a force transfer connection is obtained between the pliers partial legs  71  and  72  in the direction of the cutting mouth closure position according to the diagrams in  FIGS. 42 to 44 . A usual displacement of the pliers legs  4  and  5  toward one another accordingly brings about a pivoting displacement of the functional jaw parts  6  and  7  in the direction of the closure position, this against the force of the spring  33  provided in the scissors articulation  3 . 
     In the stop-limited cutting mouth closure position, for example, according to  FIG. 4 , the free ends of the handle regions  9  and  10  of the pliers legs  4  and  5  facing away from the cutting mouth  8  are still distanced so far from one another that no undesired clamping or cutting action can occur in this region. The selected blocking position between first blocking projection  75  and first blocking recess  74  defines the use of the tool  1  in this case merely as cable cutter  2 ′. 
     For the specific use of the tool  1  as insulation-stripping tool  2 , the first blocking projection  75  is rotatably displaced via the rotating handle  76  against the restoring force of the spring  77  from the blocking position with the first blocking recess  74 , whereafter, optionally initially while retaining the blocking release position of the blocking projection  75 , the pliers partial leg  72  on the side of the handle region, which has been released from blocking is pivotable freely about the pivot axis v of the pivot bolt  73 . 
     The pliers partial leg  72  on the side of the handle region is thus pivotable so far in the direction of the opposite pliers leg  5  that the receiving cavity  45  provided for receiving the cable  39  to be stripped of insulation is obtained according to the previously described embodiment. The first insulation-stripping cutters  14  which are preferably also pivotable here are brought into a position in which these can dip into the insulation  58  of the cable  39  lying in the receiving cavity  45  in a cutting manner. 
     Otherwise, the basic function and operating mode of the first and second insulation-stripping cutters  14  and  62 , further in particular also with regard to their pivoting bodies  12  and  13 , is substantially the same as the operating mode depicted with regard to the previously described embodiments. 
     The conversion of the tool  1 , for example, from a cable cutter  2 ′ into an insulation-stripping tool  2 , can be performed, for example, in a closed cutting mouth position, further for example, from, the stop-limited cutting mouth closed position according to  FIG. 44 . 
     In an advantageous manner, in this second pivoting position of the pliers partial leg  72  on the side of the handle region relative to the pliers partial leg  71  on the scissors articulation side, a blocking of the cutting mouth  38  is achieved so that the functional jaw parts  6  and  7  cannot pivot into an open position, in particular in a configuration of the same for cutting actuation. 
     This is substantially achieved by a second blocking projection  79  of the pliers partial leg  72  on the side of the handle region, which can dip into a second blocking recess  80  of the opposite pliers leg  5  in this second pivot position (compare  FIGS. 46, 47 and 49 ). 
     This second blocking position in the configuration of the tool  1  as an insulation-stripping tool  2  is further preferably spring-loaded, wherein in an advantageous manner the spring  77  acting on the blocking projection  74  abutting in this alignment against a facing flank  81  of the pliers leg  71  on the scissors articulation side is used. The pliers partial leg  72  on the side of the handle region, articulated to the pliers partial leg  72  on the scissors articulation side is loaded via this spring support in the direction of a closing potion of the receiving cavity  45 , wherein the resulting rotational loading at the same time brings about a loading of the second blocking projection  79  into the blocking position  79 . 
     The engagement of the second blocking projection  79  into the second blocking recess  80  allows a relative pivoting movement of the pliers partial leg  72  on the side of the handle region about the pivot axis v relative to the other pliers leg  5  (compare, for example,  FIGS. 46 and 49 ) without the blocking between second blocking projection  79  and second blocking recess  80  being cancelled (compare  FIG. 47 ). Accordingly, over the depicted and described pivoting path of the pliers partial leg  72  in the insulation-stripping configuration, even the cutting mouth  8  remains in a closed position or does not reach any open position so that when the tool  1  is used as an insulation-stripping tool  2 , there is no risk of clamping or cutting on the side of the opposite end, which can be used for example as a cable cutter  2 ′ and the functional jaw parts  6  and  7  provided here. 
       FIGS. 50 to 53  show an embodiment of an insulation-stripping tool  2  in pliers form. In this embodiment, each pliers leg  4 ,  5  substantially starting from the scissors articulation  3  forms on one side handle regions  9 ,  10  and on the other side of the scissors articulation  3  a working region. According to the previously described exemplary embodiment, on the one hand a pivoting body  12  with a first insulation-stripping cutter  14  and on the other hand a pivoting body  13  with a first insulation-stripping cutter  14  and a second insulation-stripping cutter  62  can be arranged in the working region. According to the previously described embodiment, these two pivoting bodies  12 ,  13  can be held pivotably about pivot axes y, which pivot axes y can run in the same direction to the pivot axes x of the scissors articulation  3 . 
     The largest dimension of the opening cross-section in the insulation-stripping region is adjustable by means of adjusting means  69 . 
     According to the diagram in  FIG. 54 , the hand tool can also comprise two half-body partial shells  70 , which can be arranged pivotably about a common pivot axis z and can be connected to one another. The two half-body partial shells  70  are pivotable with respect to one another, whereafter a receiving cavity  65  can be obtained between the half-body partial shells  70  in the region of the mutually facing inner sides, which cavity can be configured to be open on both sides. 
     First insulation-stripping cutters  14  can be provided in the region of one end of the receiving cavity  45 , which, according to the previously described exemplary embodiments, can be arranged on pivoting bodies  12 ,  13 , wherein further according to the diagram in  FIG. 55  a pivoting body  13  can comprise a second insulation-stripping cutter  62  arranged offset to the first insulation-stripping cutter  14 .
