[0016] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] In the related technology, it is often necessary to strip the outer sheath of the control cable in the daily work of DC secondary professionals. The tools currently used for cable stripping include wallpaper knives and wire strippers, and the work efficiency depends on the worker's manual operation proficiency. The current cable stripping method still has a wrapping force on the inner core after cutting, making it difficult for the outer sheath to be removed.

[0018] This embodiment provides a cable stripper, which can cut two axially extending cuts at both ends of the cable diameter at one time, so that the outer sheath is easier to remove after cutting.

[0019] See also Figure 1-Figure 3In this embodiment, a cable stripper includes a base 10, a roller 20 and a cutting piece 30; the base 10 is connected to two parallel supporting shafts 22, and the supporting shaft 22 includes a limiting section 23 with an increased outer diameter; the roller 20 is sleeved on the supporting shaft 22 on both sides of the limiting section 23; the cutting piece 30 is passed through the limiting section 23; wherein the two cutting pieces 30 follow the base 10 to move along the axial direction of the cable 40, and cut axially extending cuts at both ends of the diameter of the cable 40.

[0020] By adopting the technical solution of this embodiment, two cutting pieces 30 are arranged at both ends of the diameter of the cable 40, and two incisions extending along the axial direction can be cut at both ends of the diameter of the cable 40, reducing the wrapping force generated by the inner core after the outer skin is cut, making the outer skin easier to detach after cutting.

[0021] In this embodiment, the base 10 is constructed as a U-shaped plate as a whole. A driving rod 11 is provided in the U-shaped groove enclosed by the base 10. The two ends of the driving rod 11 are rotatably connected to the two side plates of the base 10. The driving rod 11 is arranged parallel to the base 10 as a whole. A disc-shaped knob 12 is fixedly connected to the middle position of the driving rod 10. The knob 12 is used to operate the driving rod 10 to rotate more conveniently. An avoidance opening 14 corresponding to the knob 12 is opened on the base 10. The knob 12 extends to the top of the base 10 through the avoidance opening 14. In order to facilitate the movement of the base 10, a handle 13 is fixedly connected to the base 10. The handle 13 and the driving rod 11 are respectively arranged on the upper and lower sides of the base 10.

[0022] It should be noted that the base 10 is suspended as a whole outside the cable 40 and moves along the axial direction of the cable 40 under human operation.

[0023] It should also be noted that the driving rods 11 on both sides of the knob 12 have threads with opposite rotation directions.

[0024] In this embodiment, a moving frame 21 is screwed onto the driving rod 11 on both sides of the knob 12. The top surface of the moving frame 21 is a plane, and the top surface of the moving frame 21 is in contact with the lower surface of the base 10, so that the moving frame 21 cannot rotate relative to the driving rod 11, that is, the moving frame 21 is only allowed to move along the axial direction of the driving rod 11 under the drive of the driving rod 11. The two moving frames 21 are symmetrically arranged on the driving rod 11. When the driving rod 11 is driven to rotate by the knob 12, the two moving frames 21 can be driven to move synchronously in opposite directions or reverse directions.

[0025] In addition, U-shaped mounting grooves are provided on the opposite side walls of the two mobile frames 21, and the support shaft 22 is fixedly connected in the aforementioned mounting groove, and the support shaft 22 is vertically arranged with the driving rod 11. At the same time, the support shaft 22 is also vertically arranged with the base 10. The two support shafts 22 on the two mobile frames 21 are arranged parallel to each other, and a limited position section 23 is integrally formed at the middle position of the support shaft 22. The limited position section 23 is constructed into a cylindrical shape coaxially arranged with the support shaft 22.

[0026] It should be noted that the support shaft 22 is fixedly connected to the movable frame 21 . For example, both ends of the support shaft 22 are welded to the upper and lower side walls of the aforementioned mounting groove, so that the support shaft 22 can move synchronously with the movable frame 21 .

[0027] In this embodiment, the roller 20 is constructed as a whole in a frustum shape, and the roller 20 is rotatably mounted on the support shaft 22 on the upper and lower sides of the limiting section 23. The roller 20 maintains a coaxial arrangement with the support shaft 22, and the roller 20 can rotate relative to the support shaft 22. The outer diameter of the roller 20 increases outward from the limiting section 23, that is, a V-shaped groove for clamping the cable 40 is formed between the upper and lower rollers 20, the smaller end of the roller 20 abuts against the end face of the limiting section 23, and the larger end abuts against the side wall of the aforementioned mounting groove, and the two rollers 20 are symmetrically arranged on the upper and lower sides of the limiting section 23.

[0028] It should be noted that when the two moving frames 21 are driven by the driving rod 11 to approach each other, the moving wheels 20 can clamp the cable 40 on both sides of the cable 40, so that the wire stripper is fixed on the cable 40 as a whole and can move along the axial direction of the cable 40.

[0029] In this embodiment, the cutting piece 30 is passed through the limiting section 23 and is threadedly connected to the limiting section 23. As an example, the cutting piece 30 is a steel needle with an external thread. The cutting piece 30 is vertically arranged with the support shaft 22. At the same time, the cutting piece 30 is parallelly arranged with the driving rod 11. The cutting piece 30 is arranged at the middle position of the limiting section 23 along the axial direction. The two rollers 20 are symmetrically arranged on the upper and lower sides of the cutting piece 30. The two cutting pieces 30 are arranged on the same straight line, so that after the roller 20 clamps the cable 40, the two cutting pieces 30 are arranged at both ends of the diameter of the cable 40.

[0030] It should be noted that the cutting depth of the cutting member 30 can be changed by rotating the cutting member 30 relative to the limiting segment 23 .

[0031] When in use, the wire stripper is first sleeved on the outside of the cable 40, and then the knob 12 is turned to drive the rollers 20 on both sides to clamp the cable 40 and keep the wire stripper as a whole able to move along the axial direction of the cable 40, and then the cutting pieces 30 on both sides are screwed into the cable 40 to a suitable depth. Finally, the wire stripper is driven by the handle 13 to move along the axial direction of the cable 40. The cutting pieces 30 on both sides can be used to cut two axially extending incisions at both ends of the diameter of the cable 40 at one time. The outer skin of the cable 40 is divided into two symmetrical parts by the two incisions, which can greatly reduce the wrapping force on the inner core of the cable 40 after the outer skin is cut, making it easier to detach the outer skin after cutting.

[0032] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
