Description

Technical Field

[0001] The invention relates to a cable stripper. Background Art

[0002] Electricity is conducted through cables, and during the wiring process, the insulation layer wrapped around the cable needs to be stripped off before it can be connected to the terminal. In order to save costs, electricians usually use a utility knife to cut the insulation layer, which poses a great safety hazard. In addition, although there are related strippers on the market, they are very inconvenient to use.

[0003] Publication No. CN 109659869 A Cable Stripper records a tool for cutting cable sheaths. The tool is provided with a cutter head at the end of a stud, and the stud is rotated to achieve the cutter head feed. The cutter head feed distance is completely adjusted by experience. If the cutter head feeds too much at once, a large force is required when cutting; and if the feed is too small, the sheath cannot be completely cut. In this case, the cutter head feed distance needs to be adjusted manually, which is cumbersome. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention 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 invention and are not used to limit the present invention.

[0025] A cable stripper, such as Figure 1-6 As shown, it comprises a wire-straightening assembly 1 and a cutting assembly 2. The cutting assembly 2 is rotatably arranged at one end of the wire-straightening assembly 1. The wire-straightening assembly 1 is used to straighten the cable; and the cutting assembly 2 is used to cut the outer skin of the cable.

[0026] The cutting assembly 2 includes a rotating block 21, a knife holder 22, a blade holder 23, a blade 24 and a driving assembly 25. A through hole 211 is provided in the middle of the rotating block 21 to allow the cable to pass through. The knife holder 22 is mounted on the rotating block 21. The blade holder 23 is slidably mounted on the knife holder 22. The blade 24 is mounted on the blade holder 23. The driving assembly 25 is used to provide a thrust for the blade holder 23 to move into the through hole 211 so that the blade 24 acts on the cable. The rotating block 21 is rotated so that the blade 24 cuts the side of the outer skin.

[0027] In one embodiment, if Figure 1-6 As shown, the driving assembly 25 includes a slider 251 and at least one group of magnetic components, the magnetic component includes a first magnet 252, a second magnet 253 and a third magnet 254, the first magnet 252 is arranged on the blade holder 23, the second magnet 253 and the third magnet 254 are arranged on the slider 251 at intervals, and the slider 251 is slidably arranged on the blade holder 22 to switch the relative positions of the second magnet 253, the third magnet 254 and the first magnet 252. Among them, the second magnet 254 and the first magnet 252 have opposite magnetic properties on the opposite surface, and the third magnet 254 and the first magnet 252 have the same magnetic properties on the opposite surface. When the cable needs to be inserted, it is only necessary to move the slider 251 so that the second magnet 253 and the first magnet 252 correspond to each other, and the blade holder 22 is driven away from the through hole 211 by magnetic attraction. When cutting, the slider 251 is pushed so that the third magnet 254 corresponds to the first magnet 252, and the blade 24 is provided with a thrust acting on the cable by using the principle that magnets of the same charge repel each other.

[0028] In one embodiment, if Figure 1-6 As shown, indicator blocks 255 are provided at both ends of the slider 251 to display the current matching state of the magnetic assembly, that is, the indicator blocks 255 are used to determine whether the first magnet 252 corresponds to the second magnet 253 or the first magnet 252 corresponds to the third magnet 254.

[0029] In one embodiment, if Figure 1-6 As shown, a slot is provided on the blade holder 23, a blade 24 is provided in the slot, and the blade 24 is tightly fitted with the slot.

[0030] In one embodiment, if Figure 1-6 As shown, the wire-strapping assembly 1 includes a base 11 and an upper cover 12. The base 11 is provided with a first wire groove 111, and the upper cover 12 is provided with a second wire groove 121. The upper cover 12 is hinged on the base 11. After being covered, the first wire groove 111 and the second wire groove 121 are combined to form a wire-strapping channel. When in use, after the cable passes through the through hole 211 and is placed in the first wire groove 111, the upper cover 12 is closed, and the cable is pulled so that the cable moves in the wire-strapping channel. After reaching the cutting position, the cable is cut by the cutting assembly 2.

[0031] In one embodiment, if Figure 1-6 As shown, an opening 13 is provided on one side of the base 11 and / or the upper cover 12, and a scale is provided at the opening 13. By observing the position of the cable end in the wire drawing channel through the opening 13, and with the help of the scale, the distance between the cutting position and the cable end can be known, so as to more conveniently adjust the cable to the cutting position.

[0032] In one embodiment, if Figure 1-6 As shown, a guide groove 14 for guiding the movement of the second blade is provided on the upper cover 12. In order to facilitate the peeling of the outer skin, a utility knife is inserted into the guide groove 14 to axially cut the cable outer skin.

[0033] In one embodiment, if Figure 1-6 As shown, the base 11 and the upper cover 12 are closed by magnetic attraction.

[0034] In one embodiment, if Figure 1-6 As shown, a plurality of hooks 256 are arranged at intervals around the through hole at one end of the rotating block 251 , and a slot 15 cooperating with the hooks 256 is arranged on the wire drawing assembly 1 .

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
