[0026] Before describing the embodiments of the present invention in detail, the application environment of the present invention is described first. The technology of the present invention is mainly applied to the field of cable stripping technology. The present invention solves the problem that when operators perform manual wire stripping, they may scratch the outer sheath of the cable and injure their hands due to excessive force, or the depth of cable stripping may be different due to inconsistent force, resulting in poor engineering quality and low processing efficiency.

[0027] Please combine Figures 1 to 5 As shown, the present invention provides a cable stripper, comprising:

[0028] Positioning component 1, wire stripping component 4.

[0029] Exemplarily, the positioning component 1 is provided with a threading channel 2 along the axial direction, and a V-shaped mounting groove is provided on the outer wall of the threading sleeve 11 for installing the tool holder 7. A mounting channel 3 for connecting with the threading channel 2 is provided on one of the inclined surfaces of the V-shaped mounting groove, and the mounting channel 3 is arranged perpendicular to the inclined surface, which is an inclined surface facing the side of the clamping member 6. A mounting portion 13 is provided on the side wall of the threading sleeve 11, and the aperture of the mounting portion 13 is smaller than the aperture of the threading channel 2.

[0030] In an exemplary embodiment, the clamping piece 6 is sleeved on the threading sleeve 11, the clamping piece 6 is provided with an internal thread, the threading sleeve 11 is provided with an external thread, the clamping piece 6 and the threading sleeve 11 are threadedly connected, the clamping piece 6 and the threading sleeve 11 are both cylinders, the clamping piece 6 is provided with a clamping portion 10, the clamping portion 10 is a frustum, and the mating surface between the clamping portion 10 and the pressure block 8 is an arc surface.

[0031] In an exemplary embodiment, the clamping member 6 is sleeved on the threading sleeve 11, and a plurality of retractable limit members are spaced apart on the threading sleeve 11. The clamping member 6 is slidably connected to the threading sleeve 11, and the mating surfaces of the clamping portion 10 and the pressure block 8 are flat.

[0032] The tool holder 7 is installed in the V-shaped mounting groove, and the pressure block 8 is arranged on the tool holder 7. The pressure block 8 is provided with an arc surface that cooperates with the clamping part 10. The arc surface cooperates and contacts with the truncated cone side of the clamping part 10. An elastic reset member 9 for resetting the wire stripping assembly 4 is connected between the pressure block 8 and the inclined surface of the V-shaped groove on which the mounting channel 3 is opened. The tool holder 7 penetrates into the mounting channel 3 and is slidably connected to the mounting channel 3.

[0033] The positioning sleeve 12 is installed on the mounting portion 13. The positioning sleeve 12 is provided with a knife groove 18 along the axial direction for the blade 5 to penetrate into the positioning sleeve 12. The positioning sleeve 12 is locked with the threading sleeve 11 through a locking piece 19. The locking piece 19 is threadedly connected to the threading sleeve 11. The locking piece 19 is provided with an entrance for threading the cable.

[0034] In this embodiment, the pressing part 10 is horizontally moved along the axis of the threading channel 2 by rotating the pressing member 6 until it contacts the arc surface of the pressing block 8, so that the arc surface of the pressing block 8 is subjected to force to push the knife holder 7 into the threading channel 2 along the installation channel 3, and the blade 5 enters the positioning sleeve 12 through the knife notch 18 on the positioning sleeve 12, and further inserts the cable. The above scheme of the present invention allows the operator to maintain a consistent stripping depth during the cable stripping operation, while improving the engineering quality and processing efficiency.

[0035] In an exemplary embodiment, the mounting portion 13 is configured as a boss inside the threading sleeve 11 .

[0036] By installing the positioning sleeve 12 into the mounting portion 13, the positioning sleeve 12 is limited in the axial direction in the direction of being installed into the threading sleeve 11 through the first positioning portion 14 on the positioning sleeve 12. During the threading operation, the positioning sleeve 12 will not be axially displaced in the threading channel 2 due to the friction between the cable and the positioning sleeve 12 when the cable is threaded.

[0037] In an exemplary embodiment, the first positioning portion 14 and the second positioning portion 15 on the positioning sleeve 12 divide the positioning sleeve 12 into two parts, and the bottom surface of the first positioning portion 14 is smaller than the second positioning portion 15, and an abutment surface 20 matching the shape of the boss of the mounting portion 13 is provided between the first positioning portion 14 and the second positioning portion 15, and the abutment surface 20 abuts against the boss of the mounting portion 13.

[0038] The positioning sleeve 12 will not be axially displaced when the cable is passed through the threading sleeve 11, and the positioning sleeve 12 is locked in the threading sleeve 11 by the locking member 19. During the wire stripping operation, the friction between the cable and the positioning sleeve 12 when passing through the threading sleeve 11 will not cause the positioning sleeve 12 to be axially displaced.

[0039] In an exemplary embodiment, at least one knife notch 18 is formed on the first positioning portion 14 . The knife notch 18 is formed from the opening of the first positioning portion 14 and ends at the abutment surface 20 , so as to expose part of the cable sheath in the first positioning portion 14 to the threading channel 2 .

[0040] By opening a knife slot 18 on the first positioning portion 14, the blade 5 can smoothly enter the positioning sleeve 12 and be inserted into the cable sheath, which is convenient for the wire stripping operation. If only one knife slot 18 is opened on the first positioning portion 14, the operator needs to install the positioning sleeve 12 in the direction of the knife slot 18; if multiple knife slots 18 are opened on the first positioning portion 14, that is, a knife slot 18 is opened on each surface, the operator can blindly install the positioning sleeve 12 when installing the positioning sleeve 12, thereby reducing the labor intensity of the operator.

[0041] In an exemplary embodiment, the first positioning portion 14 and the second positioning portion 15 of the positioning sleeve 12 are both configured as regular hexagonal prisms, and the boss of the mounting portion 13 matches the shape of the abutment surface 20 of the positioning sleeve 12 .

[0042] The positioning sleeve 12 adopts a regular hexagonal prism, which can effectively prevent the operator from causing relative rotation between the positioning sleeve 12 and the threading sleeve 11 during the threading or stripping operation, so that the operator will not damage the blade 5 due to relative rotation between the positioning sleeve 12 and the threading sleeve 11 when performing the wire stripping operation.

[0043] In an exemplary embodiment, the positioning sleeve 12 is provided with a threading hole for passing the cable along the axial direction, and the cable is loosely matched with the threading hole when passing through or passing through the threading hole.

[0044] The clearance between the cable and the threading hole can reduce the friction generated when the cable is inserted into or out of the positioning sleeve 12, thereby alleviating the working intensity of the operator.

[0045] In an exemplary embodiment, the pressing portion 10 is slidably connected to the arcuate surface of the pressing block 8 .

[0046] When the clamping member 6 is rotated, the clamping portion 10 and the arc surface of the pressure block 8 slide together, so that the clamping portion 10 and the arc surface have a larger contact area, and the tool holder 7 can be pushed into the threading sleeve 11 more quickly, thereby improving the work efficiency of the operator.

[0047] In an exemplary embodiment, the threading hole formed on the positioning sleeve 12 has trumpet-shaped openings 16 at both ends thereof, which are used to guide the cables to the threading hole when threading the cables, thereby saving operators' visual alignment time during the threading operation.

[0048] In an exemplary embodiment, according to different diameters of cables, a plurality of positioning sleeves 12 with different threading holes are designed to match the diameters of cables of various models.

[0049] The threading hole adopts a trumpet-shaped opening 16, so that when the operator performs the threading operation, the operator does not need to accurately align the threading hole with the visual aid, which has the beneficial effect of reducing the operator's work intensity and improving the work efficiency.

[0050] In an exemplary embodiment, a scale mark 18 for observing the insertion depth of the blade 5 into the threading sleeve 11 is provided on the threading sleeve 11 .

[0051] By setting scale lines on the threading sleeve 11, when the operator performs the wire stripping operation on the cable sheaths of different thicknesses, the insertion depth of the blade 5 can be determined by the scale mark 18, which effectively improves the engineering efficiency.

[0052] During operation, a suitable positioning sleeve 12 is selected according to the diameter of the cable, and the positioning sleeve 12 is installed and positioned on the mounting portion 13, so that the first limiting portion abuts against the second limiting portion, and then the locking member 19 is locked with the threading sleeve 11, and the limiting portion on the locking member 19 axially limits the end of the positioning sleeve 12 away from the first limiting portion, and the cable is inserted into the threading sleeve 11 from the end where the locking member 19 is located. After the cable of the required stripping length is inserted, the pressing member is rotated clockwise. 6, make the clamping part 10 butt against the arc surface of the pressure block 8, observe the insertion depth of the blade 5 by observing the scale line according to the cable outer skin thickness, continue to rotate the clamping part 6 until the insertion depth of the blade 5 installed on the knife holder 7 is just the same as the cable outer skin thickness, and then the operator holds the end where the locking part 19 is located with one hand and holds the cable with the other hand, and forcefully pulls it outward along the installation direction of the positioning sleeve 12 until the cable is completely withdrawn from the threading sleeve 11, and the cable stripping is completed. When stripping the next cable, rotate the clamping part 6 counterclockwise to withdraw the knife holder 7 from the threading sleeve 11, and determine whether the positioning sleeve 12 needs to be replaced according to the diameter of the cable. If it does not need to be replaced, repeat the above operation; if it needs to be replaced, repeat the above operation after replacement. The cable stripper of the present invention reduces the risk of the operator's hand injury caused by the blade 5 cutting out the cable sheath due to excessive force during the stripping operation. At the same time, it can also ensure that the stripping depth will not be inconsistent due to inconsistent force applied by the operator, thereby achieving the beneficial effect of improving the quality of the stripping project and the work efficiency of the operator.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
