[0047] In some embodiments, the fixing unit 4 can have a structure as shown in Figure 1 . Referring to Figure 1The fixing unit 4 comprises a limiting rod 41, a roller 42 and a driving member 43. The limiting rod 41 is in plurality, and the plurality of limiting rods 41 are located at the feeding end of the mounting hole and are arranged around the inner wall of the mounting hole. One end of the limiting rod 41 is hingedly arranged on the inner wall of the mounting hole, and the other end extends towards the inner wall of the mounting hole. The roller 42 is rotationally arranged at the end of the limiting rod 41 away from the inner wall of the mounting hole, and the axis of the roller 42 is perpendicular to the axis of the mounting hole. The driving member 43 is arranged between the limiting rod 41 and the fixing frame 1, and is used to drive the end of the limiting rod 41 with the roller 42 to swing towards the inside of the mounting hole. The limiting rod 41 is located at the feeding end of the mounting hole, the driving member 43 is a spring, and one end of the driving member 43 abuts against the side of the limiting rod 41 away from the feeding port of the mounting hole. The limiting rod 41 is always arranged to incline towards the inside of the fixing frame 1. In use, the cable is passed through the feeding port of the mounting hole so that the roller 42 abuts against the outside of the cable, and the driving member 43 can press the roller 42 against the cable. At the same time, when the cable is pulled out of the mounting hole, the limiting rod 41 can be swung towards the feeding port of the mounting hole. Thus, the roller 42 can be more tightly pressed against the outside of the cable, the cable cannot be automatically removed from the feeding port of the mounting hole, and the stability of the cable during the fixing process is improved.

[0048] In some embodiments, the fixing unit 4 described above can adopt the structure as shown in Figure 1 . Referring to Figure 1 , the fixing unit 4 further comprises an unloading cylinder 44.

The outside of the unloading cylinder 44 is provided with external threads, and the inner wall of the feeding port of the mounting hole is provided with a threaded hole threadedly connected with the unloading cylinder 44. By rotating the unloading cylinder 44 on the fixing frame 1, the unloading cylinder 44 can be moved towards the limiting rod 41. When the end of the unloading cylinder 44 abuts against the limiting rod 41, the limiting rod 41 can be driven to rotate away from the cable, so that the roller 42 is separated from the cable, and the processed cable can be pulled out of the mounting hole. The use is convenient and the operation is convenient.

[0049] In some embodiments, the driving unit 5 described above can adopt the structure as shown in Figure 1 , Figure 3 . Referring to Figure 1 , Figure 3The driving unit 5 comprises a driving rod 51, a rotating sleeve 52 and a transmission assembly 53. The driving rod 51 is rotatably arranged on the fixed frame 1. The rotating sleeve 52 is rotatably arranged on the fixed frame 1, and the axis of the rotating sleeve 52 is coaxially arranged with the axis of the mounting hole. The rotating disc 2 is fixedly arranged on the rotating sleeve 52. The transmission assembly 53 is arranged between the driving rod 51 and the rotating sleeve 52, and is used for driving the rotating sleeve 52 to rotate when the driving rod 51 rotates. The axis of the rotating sleeve 52 is coaxially arranged with the axis of the mounting hole. In use, the cable extends out of the fixed frame 1 from the discharge port of the mounting hole after passing through the inner hole of the rotating sleeve 52. Thus, the cable can not rotate, and the first cutter 33 rotates relative to the cable, so that the first cutter 33 can rotate around the circumference of the cable to cut the outer skin of the cable end. In the embodiment, the transmission assembly 53 comprises two T-shaped gears which are meshed with each other. The axis of the driving rod 51 is perpendicular to the axis of the rotating sleeve 52. The two T-shaped gears are fixedly connected with the driving rod 51 and the rotating sleeve 52 respectively, and are coaxially arranged with the driving rod 51 and the rotating sleeve 52 respectively. Thus, the driving rod 51 can drive the rotating sleeve 52 to rotate when the driving rod 51 rotates. The rotating disc 2 is sleeved on the rotating sleeve 52, and a rotation prevention key is further arranged between the rotating disc 2 and the rotating sleeve 52, so that the rotating sleeve 52 can drive the rotating disc 2 to rotate when the rotating sleeve 52 rotates.

[0050] Optionally, in the embodiment, the driving source of the driving rod 51 can be a motor or a manual driving rotation.

[0051] In some embodiments, the above-mentioned guiding assembly 21 can adopt the structures shown in Figure 1 Figure 2 and Figure 3 . Referring to Figure 1 Figure 2 and Figure 3 , the rotating disc 2 is further provided with a guiding assembly 21 for guiding the cable. The guiding assembly 21 comprises a connecting rod 211 and an elastic member 213. The number of the connecting rod 211 is two. One end of each of the two connecting rods 211 is hingedly connected to the sliding block 3, and the other end is rotatably provided with a guiding wheel 212. The axis of the guiding wheel 212 is parallel to the axis of the mounting hole. The elastic member 213 is arranged between the two connecting rods 211, and is used for driving the two connecting rods 211 to rotate towards each other. When the cable is conveyed to the discharge port of the mounting hole, the two guiding wheels 212 abut against the outer side of the cable, and the cable is clamped between the two guiding wheels 212 under the driving of the elastic member 213. In the embodiment, the number of the sliding block 3 is two, and the two sliding blocks 3 are oppositely arranged along the radial direction of the mounting hole. Thus, the cable can be clamped between the four guiding wheels 212, and the position of the cable is fixed. Thus, the first cutter 33 can ensure the cutting depth of the outer skin of the cable during cutting.

[0052] ​​Optionally, in the embodiment, the guide assembly 21 is located at the side of the first cutter 33 close to the discharge port of the mounting hole.

[0053] In some embodiments, the guide assembly 21 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the number of the sliding blocks 3 is two, and the two sliding blocks 3 are oppositely arranged on the rotating disc 2 and are arranged in a sliding manner. A connecting assembly 32 for synchronously sliding the two sliding blocks 3 is further arranged between the two sliding blocks 3. The two sliding blocks 3 are arranged on the rotating disc 2 in a sliding manner along the radial direction of the mounting hole, and the connecting assembly 32 can make the sliding blocks 3 keep synchronous movement. When the four guide wheels 212 press the cable, the axis of the cable and the axis of the rotating disc 2 keep coaxial arrangement.

[0054] In some embodiments, the connecting assembly 32 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the connecting assembly 32 comprises a guide block 321 and a support rod 322. The guide block 321 is arranged on the rotating disc 2 in a sliding manner along the radial direction of the rotating disc 2 and is arranged in a direction perpendicular to the sliding direction of the sliding block 3. The number of the support rods 322 is multiple, and the support rods 322 are arranged between the guide block 321 and the sliding block 3. One end of the support rod 322 is hingedly arranged on the guide block 321, and the other end of the support rod 322 is hingedly arranged on the sliding block 3. The number of the guide blocks 321 is two, and the sliding direction of the two guide blocks 321 and the sliding direction of the two sliding blocks 3 are both in the radial direction of the rotating disc 2 and are arranged in a direction perpendicular to each other. When one of the two sliding blocks 3 slides on the rotating disc 2, it can simultaneously drive the two guide blocks 321 to slide together. When the two guide blocks 321 slide, the other sliding block 3 on the rotating disc 2 can be synchronously driven to slide. Thus, when one sliding block 3 is driven to slide, the other sliding block 3 can be driven to move together, and the synchronous pressing operation of the guide wheels 212 on the two sliding blocks 3 can be realized.

[0055] In some embodiments, the fixed frame 1 can adopt the structure as shown in Figure 1 , Figure 4 . Referring to Figure 1 , Figure 4 , the mounting block 6 is further arranged on the fixed frame 1 in a sliding manner along the axis direction of the mounting hole, and the second cutter 61 arranged in the radial direction of the mounting hole is mounted on the mounting block 6. The mounting block 6 and the fixed frame 1 are further provided with a pushing assembly 7 for driving the mounting block 6 to slide. The cutting edge of the second cutter 61 is arranged towards the discharge port of the mounting hole. After the first cutter 33 cuts the cable sheath, the pushing assembly 7 can drive the first cutter 33 to move towards the discharge port of the mounting hole, and a gap can be cut on the cable sheath along the length direction of the cable, so that the cable sheath can be easily removed from the cable.

[0056] In some embodiments, the pushing assembly 7 can adopt the structure as shown in Figure 1 、 Figure 4 . See also Figure 1 、 Figure 4 , the pushing assembly 7 comprises a rotating gear 71, a connecting plate 72, a driving disc 73, a toothed rod 74 and a pushing piece 75. The rotating gear 71 is rotationally arranged on the fixed frame 1, and a rotating rod is fixedly connected to the rotating gear 71 and arranged eccentrically and parallel to the axis of the rotating gear 71. One end of the connecting plate 72 is hingedly arranged on the rotating rod, and the other end is hingedly arranged on the mounting block 6. The driving disc 73 is fixedly mounted on the driving rod 51 and coaxially arranged with the driving rod 51. The middle part of the toothed rod 74 is hingedly arranged on the driving disc 73, one end of the toothed rod 74 can extend out of the driving disc 73 and mesh with the rotating gear 71. The pushing piece 75 is arranged between the toothed rod 74 and the driving disc 73, and is used to push one end of the toothed rod 74 to extend outward of the driving disc 73. The driving disc 73 comprises two mounting plates arranged in parallel along the axis direction of the driving rod 51, and the projection of the mounting plate along the axis direction of the driving rod 51 is circular. A plurality of toothed rods 74 are hingedly arranged between the two mounting plates. In the free state, one end of the toothed rod 74 is abutted on the outside of the rotating shaft of the driving disc 73 under the action of the pushing piece 75, and the other end is located on the outside of the driving disc 73. When the driving disc 73 rotates in the first direction, one end of the toothed rod 74 is abutted on the teeth of the rotating gear 71, so that the other end can be abutted on the teeth of the rotating gear 71 to drive the rotating gear 71 to rotate, and the connecting plate 72 is pulled to slide the mounting block 6. When the driving disc 73 rotates in the second direction, one end of the toothed rod 74 is abutted on the rotating gear 71, so that the toothed rod 74 can swing on the driving disc 73, so that the toothed rod 74 turns into the inside of the driving disc 73, and can avoid driving the rotating gear 71 to rotate in the second direction. In use, the driving rod 51 is first driven to rotate in the second direction, so that the first cutter 33 cuts the cable sheath in the circumferential direction. Then the driving rod 51 is driven to rotate in the first direction to separate the cut cable sheath in the length direction of the cable. Only the rotation of the driving rod 51 needs to be operated to complete the separation of the cable sheath in the circumferential direction and the length direction. The operation is simple and convenient.

[0057] In some embodiments, the connecting plate 72 can adopt the structure as shown in Figure 1 、 Figure 4 、 Figure 5 .
