[0011] This utility model provides a cable sheath cutting device for cable connectors. It has the following advantages: (1) The cable sheath cutting device for cable joints has three arc-shaped rotating blocks that move radially synchronously under the drive of the groove of the first rotating ring. The rotating blocks automatically push the cable to the center of the fixed cylinder and fix the cable, completely eliminating manual alignment deviation. After the cable is centered, the second threaded column is screwed to push the conical cutting cone into the sheath. At this time, the rotating auxiliary rod drives the second rotating ring to rotate. The third rotating ring stably transmits power in the second rotating cavity, so that the double cutting cone cuts around the cable axis. The determination of the position reduces the copper core damage rate.

[0012] (2) The cable sheath cutting device for cable connectors reduces the pressure on the rotating block by rotating the first rotating ring, so that the rotating ball keeps in contact with the cable and reduces the friction between the cable. This allows the cable to be pulled, so that the cable is cut by two conical cutting cones during the movement. Attached Figure Description

[0017] like Figures 1-4As shown, a cable sheath cutting device for cable connectors includes a fixed cylinder 1. Three first rotating cavities 2 are equidistantly spaced circumferentially formed on the inner side of the fixed cylinder 1. A rotating block 3, which is arc-shaped, is rotatably mounted inside each of the first rotating cavities 2. A first rotating ring 6 is rotatably mounted on the outer side of the fixed cylinder 1, corresponding to the positions of the first rotating cavities 2. A groove 7 is formed on the side of the first rotating ring 6, corresponding to the position of the rotating block 3. A second rotating ring 10 is rotatably mounted on the outer side of the fixed cylinder 1. Two movable cutting cones 14, which are conical, are provided on the inner side of the second rotating ring 10. When used outdoors, the cable is passed through the fixed cylinder 1 and the second rotating ring 10. Rotating the first rotating ring 6 causes it to press against the rotating block 3 through the side of the groove 7. The three rotating blocks 3 move synchronously, pressing the cable until it is positioned at the center of the fixed cylinder 1. Moving the two cutting cones 14 cuts the plastic sheath of the cable. The cable is extruded and cut by rotating the second rotating ring 10, which drives the cutting cone 14 to rotate. The rotating cutting cone 14 cuts the plastic sheath of the cable. During the cutting process, the cable is kept in the center position to protect the copper wire in the center of the cable. Two connecting blocks 11 are fixedly installed on the outside of the second rotating ring 10. The connecting blocks 11 have a second threaded hole 12 inside, which penetrates the wall of the connecting blocks 11 and the second rotating ring 10. The second threaded hole 12 is threadedly connected to a second threaded post 13. The cutting cone 14 is fixedly installed at one end of the second threaded post 13 that extends into the second rotating ring 10. Rotating the second threaded post 13 drives the cutting cone 14 to move and cut the cable. Rotating the second rotating ring 10 drives the cutting cone 14 to rotate, and the rotation of the cutting cone 14 performs a circumferential cut on the cable. The rotating block 3 has a mounting cavity 4 on its side. A rotating ball 5 is rotatably mounted inside the mounting cavity 4. During use, the rotating ball 5 contacts the surface of the cable without squeezing the cable. The position of the cutting cone 14 is adjusted, and the cable is pulled. During the movement of the cable, it is squeezed by the two cutting cones 14 to dissect the cable. A second rotating cavity 18 is opened on the outside of the fixed cylinder 1 corresponding to the position of the second rotating ring 10. A third rotating ring 19 is rotatably mounted inside the second rotating cavity 18. The outside of the third rotating ring 19 is fixedly connected to the inside of the second rotating ring 10. The second rotating ring 10 moves on the outside of the fixed cylinder 1 through the second rotating cavity 18 and the third rotating ring 19. The first rotating ring 6 has first threaded holes 8 evenly spaced on its side. The first threaded holes 8 are internally threaded with first threaded posts 9. By rotating the first threaded posts 9, the first threaded posts 9 press against the outside of the fixed cylinder 1 to restrict the movement of the first rotating ring 6. A handle 16 is fixedly installed on the outside of the fixed cylinder 1. Two support legs 17 are fixedly installed on the side of the fixed cylinder 1. The fixed cylinder 1 is placed on the ground by the support legs 17 and the handle 16 is held by hand for easy cutting. An auxiliary rod 15 is fixedly installed on the outside of the second rotating ring 10. The auxiliary rod 15 is provided with an anti-slip sleeve. The auxiliary rod 15 facilitates the rotation of the second rotating ring 10, making it easy to use.

[0018] The working principle of this utility model: When in use outdoors, the cable is inserted through the inside of the fixing cylinder 1 and the second rotating ring 10. The first rotating ring 6 is rotated, and it presses against the rotating block 3 through the side of the groove 7. The three rotating blocks 3 move synchronously, pressing the cable to the center position inside the fixing cylinder 1. The two cutting cones 14 are moved to cut the plastic sheath of the cable. The second rotating ring 10 is rotated, causing the cutting cones 14 to rotate and cut the plastic sheath of the cable. During the cutting process, the cable is kept in the center position to minimize damage to the copper wire at the center of the cable. The second threaded post 13 is rotated, causing... The cutting cone 14 moves to cut the cable. The second rotating ring 10 rotates, causing the cutting cone 14 to rotate. The rotation of the cutting cone 14 cuts the cable in a ring. During use, the rotating ball 5 contacts the surface of the cable without squeezing it. The position of the cutting cone 14 is adjusted, and the cable is pulled. During the movement, the cable is squeezed by the two cutting cones 14 to dissect the cable. The second rotating ring 10 moves outside the fixed cylinder 1 through the second rotating cavity 18 and the third rotating ring 19. The fixed cylinder 1 is placed on the ground by the support leg 17. The cutting operation is conveniently performed by holding the handle 16. The second rotating ring 10 is conveniently rotated by the auxiliary rod 15. It is easy to use.
