That is, in the present embodiment, one end of the shank link portion 53 slidably connected to the fixed link portion 52 is slidable on the fixed link portion 52, and the sliding trajectory is a circumferential trajectory centered on the cutting edge of the skinning knife 54 to which the shank link portion 53 is connected. Thus, when the connecting position and the direction of the handle connecting part 53 and the fixed connecting part 52 are adjusted in the cutter 5, the position of the peeling knife 54 can be adjusted, but the position of the knife tip of the peeling knife 54 is ensured to be unchanged, namely, the angle between the peeling knife 54 and the cable A is adjusted, the peeling position is not changed, and therefore the cable A can be effectively peeled according to different peeling angle requirements.

In this embodiment, the fixed connection portion 52 and the handle connection portion 53 are connected in a fitting manner, and guide structures which are matched with each other are arranged on the fixed connection portion 52 and the handle connection portion 53, and the guide structures are used for guiding the handle connection portion 53 to slide on the arc-shaped track. Specifically, the fixed connecting portion 52 is provided with a slot 520 therein, and the handle connecting portion 53 includes an insert plate 531; the insert plate 531 is inserted into the slot 520 and forms a sliding fit. The guiding structure includes a first sliding slot 521 and a second sliding slot 522 disposed on the fixed connecting portion 52 and communicated with the slot 520, and a first limiting member 5321 and a second limiting member 5322 disposed on the insertion plate 531. The first sliding chute 521 and the second sliding chute 522 are both arc-shaped chutes, the circumferences of the first sliding chute 521 and the second sliding chute 522 are concentric circles, the first limiting part 5321 penetrates through the first sliding chute 521 and is in sliding fit, and the second limiting part 5322 penetrates through the second sliding chute 522 and is in sliding fit; the first limiting member 5321 is connected to a first locking member 5323 for locking the fixing connection portion 52 and the insertion plate 531, and the second limiting member 5322 is connected to a second locking member 5324 for locking the fixing connection portion 52 and the insertion plate 531. Therefore, when the peeling knife 54 is selected, the first sliding chute 521 and the second sliding chute 522 are ensured to be positioned on the circumference which takes the knife tip of the peeling knife 54 arranged on the knife handle connecting part 53 as the center of a circle, so that the sliding tracks of the first limiting part 5321 and the second limiting part 5322 are concentric circles, that is, the peeling knife 54 is limited to rotate only by taking the knife tip as the center of a circle, that is, the adjustment of the knife angle of the peeling knife 54 is facilitated, and the knife tip offset of the peeling knife 54 is avoided. And the circle center angles corresponding to the first sliding chute 521 and the second sliding chute 522 are overlapped to reduce the volume of the fixed connecting part 52.

Specifically, in the present embodiment, the fixed connection portion 52 includes a first stopper 524 and a second stopper 525. The first blocking plate 524 and the second blocking plate 525 have a gap therebetween to serve as the insertion groove 520. In a specific implementation, a spacer 523 may be disposed between the first blocking plate 524 and the second blocking plate 525 to form a gap, and the spacer 523 may be fixedly connected to the mounting portion 51, or the spacer 523 may be formed by extending the mounting portion 51. In this embodiment, the first baffle 524 and the second baffle 525 are provided with the first sliding groove 521 corresponding in position, and the first baffle 524 and the second baffle 525 are provided with the second sliding groove 522 corresponding in position. Thus, the first limiting member 5321 passes through the first blocking plate 524, the insert plate 531 and the second blocking plate 525 via the two first sliding slots 521, and the second limiting member 5322 passes through the first blocking plate 524, the insert plate 531 and the second blocking plate 525 via the two second sliding slots 522. In an embodiment, the first and second limiting members 5321 and 5322 can be implemented as screws, and the first and second locking members 5323 and 5324 can be implemented as nuts. Thus, the first limiting member 5321 and the first locking member 5323 form a screw locking mechanism, and the second limiting member 5322 and the second locking member 5324 form a screw locking mechanism, so as to realize the positioning of the insertion plate 531 in the slot 520. In an embodiment, the first position-limiting member 5321 may be implemented as a screw penetrating through the insert plate 531 and having two ends respectively extending from the first blocking plate 524 and the second blocking plate 525 to connect the nut, or as two screws extending from two sides of the insert plate 531. The second position-limiting member 5322 is disposed in the same manner.

The fixed connecting part 52 is provided with scales for indicating the rotation angle of the inserting plate 531, the handle connecting part 53 is provided with a pointer 533, and the indicating direction of the pointer 533 is collinear with the central connecting line of the first limiting part 5321 and the second limiting part 5322, so that the rotation angle of the peeling knife 54 can be judged according to the corresponding relationship between the pointer 533 and the scales. In practical implementation, the pointer 533 can be disposed on the board 531 or at the connection between the board 531 and the skinning knife 54.

In the present embodiment, the fixed link 52 is provided with a first scale 526 corresponding to the first chute 521 and a second scale 527 corresponding to the second chute 522. Specifically, the first scale 526 is a circle center angle scale of the circumference where the first sliding chute 521 is located, and the second scale 527 is a circle center angle scale of the circumference where the second sliding chute 522 is located. In this way, the angle of the skinning knife 54 connected to the handle connecting portion 53 can be adjusted according to the scale indicated by the pointer 533. Meanwhile, the first scale 526 and the second scale 527 are arranged to prevent the peeling knife 54 from rotating around the first limiting member 5321 or the second limiting member 5322 during the adjustment process.

The peeling knife 54 is of a semicircular structure, and the central axis direction of the peeling knife 54 is perpendicular to the axial direction of the cable A clamped by the upper clamping part 1 and the lower clamping part 2, so that an accommodating space is provided for the cut cable skin through the semicircular structure, and the cut cable skin is prevented from influencing the subsequent peeling work.

Specifically, in the present embodiment, the mounting holes corresponding to the positions of the mounting portion 51 and the second sliding plate 43 are provided as a connecting structure, so that the mounting portion 51 and the second sliding plate 43 can be fixedly connected through a screw or a pin adapted to the mounting hole. The mounting hole is a threaded hole or a waist-shaped hole.

In this embodiment, the insulation skin thickness of the cable a to be stripped can be known according to the specification and model of the cable a to be stripped, and the feed depth of the stripping knife 54 can be determined, and the feed depth is realized by the number of rotation cycles of the output shaft of the second driving element 441. Therefore, in step S3, the cutting depth of the cutting tool 5 can be accurately controlled by setting the operation mode of the second driving element 441 in advance according to the specification of the cable to be stripped currently.

The different of cable insulation skin thickness means that the requirement of the depth of cut of skinning knife 54 is different, and this device is through corresponding the different number of revolutions of the output shaft of second drive element 441 with different depth of cut, ensures that this device can adapt to the technological requirement of skinning that satisfies multiple specification cable.

Similarly, in this embodiment, the relative distance between the upper clamping portion 1 and the lower clamping portion 2 can be achieved by the first driving unit 34, that is, in step S2, the relative distance between the upper clamping portion 1 and the lower clamping portion 2 can be determined according to the number of rotation cycles of the output shaft of the driving motor 341, so as to control the operation mode of the driving motor 341 according to the diameters of cables of different specifications and models, so as to ensure that the relative distance between the upper clamping portion 1 and the lower clamping portion 2 is matched with the clamped cable.

When the cable peeling device works, the cable peeling device rotates along a spiral line coaxial with a clamped cable, and because the peeling knife 54 cuts into the cable skin, the peeling knife 54 realizes the circular cutting of the skin of the cable A along with the rotation of the cable peeling device; meanwhile, the peeling knife 54 also axially translates along the cable A along with the translation motion of the cable peeling device, so that the cable A is spirally peeled. Specifically, both ends of the spiral line are provided with closed circles to ensure that the stripped cable skin is separated from the cable. Specifically, in the implementation, the axial translational motion of the cable stripping device along the cable a starts after the circular motion of the cable stripping device and ends before the circular motion of the cable stripping device.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
