Description

Technical Field

[0001] This invention relates to the field of wire stripping equipment technology, and more particularly to a simple manual wire stripping device. Background Technology

[0002] In existing technologies, the cutting depth judgment of manual wire stripping equipment largely relies on the operator's experience and feel or mechanical scale markings. It lacks a layer recognition and accurate feedback mechanism for the multi-layer structure of cables. Mechanical scales are prone to adjustment deviations due to visual errors or operational shaking, making it difficult for users to accurately control the cutting depth. This can lead to situations where the cable conductor is damaged when the cutting is too deep, or the cutting is incomplete when the cutting is insufficient, requiring a second operation. This not only reduces the accuracy and efficiency of wire stripping but also raises the operating threshold. It is especially unsuitable for beginners or for stripping multi-type, multi-layer cables, and cannot meet the usage requirements for high cutting accuracy. Summary of the Invention

[0003] The purpose of this invention is to provide a simple manual wire stripping device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention provides a simple manual wire stripping device, comprising: Matrix; A cable carrying structure is assembled on the base and includes a cable pre-insertion structure and a cable clamping structure to fix the cable in the cable pre-insertion structure and clamp and fix the cable together with the cable pre-insertion structure in the cable clamping structure. A cable cutting assembly includes a cutting blade for cutting cables and a blade cutting depth adjustment part. The cutting end of the cutting blade corresponds to the cable arrangement located within the cable clamping structure, and the cutting depth of the cutting blade is adjusted by the blade cutting depth adjustment part. A conductive cut depth detection component is assembled in series on the cutting blade so that it forms a path with the internal conductor of the cable when the cutting blade cuts in, and the cut depth of the cutting blade is detected by the continuity of the series circuit.

[0005] Preferably, the cable pre-insertion structure includes two first V-shaped plates with two openings arranged opposite each other to clamp the cable between the two first V-shaped plates and to secure it by screws.

[0006] Preferably, the cable clamping structure includes two second V-shaped plates with openings arranged opposite each other and a control handle. One of the second V-shaped plates is fixed to the base, and the other second V-shaped plate is slidably mounted on the base via an adjusting screw. The control handle is fixedly mounted on the other end of the adjusting screw to adjust the relative distance between the two second V-shaped plates.

[0007] Preferably, a support plate is vertically fixed along its axial direction at the lower end of the opening side of the second V-shaped plate fixed to the substrate to provide stop support for the cable pre-insertion structure.

[0008] Preferably, there are two cutting blades symmetrically distributed on both sides of the cable clamping structure, and the blade cutting depth adjustment unit synchronously adjusts the two cutting blades to cut into the cable.

[0009] Preferably, the blade cutting depth adjustment part includes a bidirectional threaded screw and an adjustment knob. Two sets of mating nuts are coaxially fixed on the side walls of the two cutting blades. The two sets of mating nuts are respectively threaded onto the two reverse threads of the bidirectional threaded screw. The knob is fixedly mounted on the top of the bidirectional threaded screw so that the bidirectional threaded screw can be rotated synchronously to adjust the two cutting blades in opposite directions.

[0010] Preferably, a limiting groove is fixed on the substrate corresponding to the ends of the two cutting blades to restrict the movement direction of the two cutting blades.

[0011] Preferably, the conductive cut depth detection component includes a low-voltage power supply module, a signal detection module, and a signal feedback module connected in series. The input terminal of the low-voltage power supply module is electrically connected to one of the cutting blades, and the output terminal of the signal feedback module is electrically connected to the other cutting blade, so that a path is formed when the two cutting blades simultaneously contact the internal conductor of the cable. The signal detection module detects the path signal and feeds it back to the user through the signal feedback module.

[0012] Preferably, the cable includes a conductor and an insulation layer, a shielding layer, and a protective layer coaxially sleeved from the inside out. The cutting edges of the two cutting blades are both provided with a preset tilt angle with the cable axis, and the cutting edges of the two cutting blades adopt a stepped cutting edge structure. The stepped cutting edge structure includes a wide cutting edge adapted to cutting the cable protective layer and a narrow cutting edge adapted to cutting the cable shielding layer and insulation layer.

[0013] Preferably, the signal detection module has two current detection thresholds corresponding to the current when the cutting blade contacts the cable's shield and conductor respectively, and the signal feedback module is a multi-color indicator light to display and distinguish the conduction state of different current magnitudes through different colored light signals.

[0014] Therefore, the present invention employs the above-mentioned simple manual wire stripping device, which has the following beneficial effects: 1. The cable bearing structure achieves precise positioning and stable clamping of the cable through a dual fixing design of cable pre-insertion structure and cable clamping structure. The first V-shaped plate can quickly pre-fix the cable, and the screw-type spacing adjustment of the second V-shaped plate can adapt to the fixing needs of cables with different diameters. The stop support of the support plate prevents the cable pre-insertion structure from shifting, ensuring that the cable has no axial slippage or radial deformation during cutting, laying the foundation for subsequent precise cutting. At the same time, the opening design of the V-shaped plate can disperse the clamping force and prevent damage to the outer layer or internal conductor of the cable.

[0015] 2. The distance between the two second V-shaped plates can be adjusted by rotating the control handle. The operation is convenient and the clamping force is controllable. This ensures the stability of the cable during the cutting process and avoids cable damage caused by excessive clamping. The support plate of the second V-shaped plate on the fixed side not only realizes the positioning support of the cable pre-insertion structure, but also restricts the axial displacement of the cable, further improving the alignment accuracy during cutting. It is especially suitable for rapid positioning and fixing during batch wire stripping, thus improving work efficiency.

[0016] 3. The cutting blades adopt a dual symmetrical distribution design, combined with a synchronous adjustment structure and limiting groove of bidirectional threaded screw. The two blades can be moved synchronously in opposite directions by a single knob, ensuring that the cutting depth on both sides is completely consistent. This avoids damage to the conductor due to excessive cutting on one side or incomplete cutting due to insufficient cutting on the other side. The limiting groove strictly restricts the movement direction of the blades to prevent blade deviation during cutting and ensures the regularity of the cutting trajectory. With the symmetrical layout of the two blades, there is no need to rotate the equipment. Cutting can be completed simply by pulling the cable axially, simplifying the operation process and improving cutting efficiency and consistency.

[0017] 4. The stepped blade structure and preset tilt angle design of the cutting blade are adapted to the material differences of the multi-layered cable structure. The wide blade can efficiently cut through the thicker and harder protective layer, while the narrow blade can accurately cut into the thinner shielding and insulation layers, avoiding problems such as entanglement and tearing during cutting. The tilt angle between the blade edge and the cable axis increases the cutting force area, improves the cutting sharpness and smoothness, achieves a thorough cut without damaging the inner structure, and broadens the range of cable types that the equipment is applicable to.

[0018] 5. The low-voltage power supply module ensures operational safety and avoids the risk of electric shock; the dual current threshold can accurately distinguish the different states of the blade contacting the shielding layer and the conductor, and the multi-color indicator light intuitively reflects the cutting progress, i.e., not contacting the conductive layer → contacting the shielding layer → contacting the conductor. This completely solves the problem of traditional wire stripping equipment relying on experience to judge the cutting depth, effectively preventing over-cutting that damages the conductor or under-cutting that leads to incomplete cutting, lowering the operation threshold, enabling quick mastery of precise wire stripping skills, and significantly improving wire stripping accuracy and product yield.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of this application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0024] It should be noted that the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or server that includes a series of steps or units, not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or device.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Existing manual wire stripping equipment generally lacks a precise layer identification and feedback mechanism for the multi-layered structure of cables in judging the cutting depth. It relies heavily on manual experience or a single mechanical scale, making it difficult to distinguish the contact state between the shielding layer and the conductor. This leads to excessive cutting that damages the conductor, and insufficient cutting that results in incomplete cutting and requires secondary operation. The cutting process is also prone to insulation layer entanglement and tearing. This not only reduces the accuracy and efficiency of wire stripping and increases the risk of hand fatigue and subsequent line failure, but also raises the operating threshold and limits its applicability in confined spaces or batch operation scenarios. It is difficult to meet the precise wire stripping requirements of multi-type and multi-layered cables.

[0027] Based on the above analysis, this invention is designed, see appendix. Figure 1-2 A simple manual wire stripping device, comprising: Matrix 1; The cable carrying structure 2 is assembled on the base 1 and includes a cable pre-insertion structure 21 and a cable clamping structure 22 to fix the cable in the cable pre-insertion structure 21 and clamp and fix it together with the cable pre-insertion structure 21 in the cable clamping structure 22. The cable cutting assembly 3 includes a cutting blade 31 for cutting cables and a blade cutting depth adjustment part 32. The cutting end of the cutting blade 31 corresponds to the cable arrangement located in the cable clamping structure 22, and the cutting depth of the cutting blade 31 is adjusted by the blade cutting depth adjustment part 32. The conductive cutting depth detection component 4 is assembled in series on the cutting blade 31 so that when the cutting blade 31 cuts in, it forms a path with the internal conductor of the cable so as to detect the cutting depth of the cutting blade 31 by the continuity of the series circuit.

[0028] In a specific embodiment of the cable pre-insertion structure 21 of this invention, the cable pre-insertion structure 21 includes two first V-shaped plates 211 with opposite openings to clamp the cable between the two first V-shaped plates 211 and fix it by screws. The V-shaped openings can achieve adaptive centering clamping of cables of different diameters by utilizing their own structural characteristics. They can adapt to various specifications from thin electronic wires to thick power cables without changing special clamps. At the same time, the screw tightening method can precisely adjust the clamping force, which not only ensures the stability of the cable after pre-fixation and avoids axial slippage or radial displacement during subsequent cutting and axial pull-out, but also prevents damage to the outer protective layer or the fragile internal conductor of the cable by uniformly distributing the clamping force. In addition, the simple V-shaped plate structure and screw fixing method are easy to operate and can quickly complete the pre-positioning of the cable, providing a benchmark for the precise clamping of the subsequent cable clamping structure, and further improving the positioning accuracy and work efficiency of the overall wire stripping process.

[0029] In a specific embodiment of the cable clamping structure 22 of this invention, the cable clamping structure 22 includes two second V-shaped plates 221 with opposite openings and a control handle 222. One second V-shaped plate is fixed to the base 1, and the other second V-shaped plate is slidably mounted on the base 1 via an adjusting screw 223. The control handle 222 is fixedly mounted on the other end of the adjusting screw 223 to adjust the relative distance between the two second V-shaped plates 221. The cooperative design of the fixed side and the sliding side ensures the symmetry and stability of the clamping, providing a reliable positioning reference for the precise cutting of the cutting blade 31. At the same time, the self-locking property of the helical drive can maintain the clamping state and prevent loosening during operation. The operation is convenient and the force is controllable, which not only reduces the intensity of manual operation, but also effectively prevents damage to the outer layer of the cable caused by over-clamping or cutting deviation caused by loose clamping, further improving the accuracy and efficiency of wire stripping operations.

[0030] In the above embodiment, a support plate 2211 is vertically fixed along its axial direction at the lower end of the opening side of the second V-shaped plate fixed on the base 1 to provide stop support for the cable pre-insertion structure 21. This provides a precise axial guide and radial support reference for the cable pre-insertion structure 21, quickly defining the installation position of the pre-insertion structure. Before clamping and fixing, the second V-shaped plate facilitates the installation and insertion of the cable pre-insertion structure 21, preventing lateral displacement and falling during insertion and clamping. This ensures precise alignment of the relative positions of the cable pre-insertion structure 21, the cable clamping structure 22, and the cutting blade 31, thereby guaranteeing the coaxiality of the cutting trajectory of the cutting blade 31 with the cable axis and preventing problems such as excessively deep cutting on one side or irregular cutting due to positioning deviations.

[0031] In addition, a stop plate 2212 is fixed at one end of the second V-shaped plate fixed on the base 1 to stop the first V-shaped plate. At the same time, the stopping function of the stop plate 2212 enhances the installation stability of the cable pre-insertion structure 21, effectively disperses the axial tension, and prevents the cable pre-insertion structure 21 from shifting with the cable when the cable is pulled. This reduces the difficulty of positioning and adjustment during operation, improves the consistency and efficiency of batch operations, and further ensures that the conductor is not damaged and the outer structure is completely cut during the stripping process.

[0032] In one specific embodiment of the present invention regarding the cutting blades 31, there are two cutting blades 31 symmetrically distributed on both sides of the cable clamping structure 22. The blade cutting depth adjustment unit 32 synchronously adjusts the two cutting blades 31 to cut into the cable. The symmetrical layout ensures that the cutting blades 31 are symmetrically distributed with the cable axis. The synchronous adjustment mechanism can ensure that the cutting depth of the cutting blades 31 on both sides is completely consistent, avoiding the problem of damaging the conductor due to excessive cutting depth on one side or incomplete cutting due to insufficient cutting depth on one side. There is no need to adjust each individual cutting blade 31 separately. The depth calibration on both sides can be completed through only one set of adjustment units, simplifying the operation process, reducing the adjustment difficulty, and improving the work efficiency and batch stripping consistency. At the same time, the balanced cutting force generated by symmetrical cutting can avoid the cable being deviated by force. Combined with the axial pull-out cutting method, it further ensures that the cutting trajectory is coaxial with the cable, which not only improves the smoothness of cutting, but also adapts to the cutting needs of cables with different diameters, broadens the versatility of the equipment, and ensures that the conductor is undamaged and the outer structure is completely stripped after stripping.

[0033] In the above embodiment, the blade cutting depth adjustment unit 32 includes a bidirectional threaded screw 321 and an adjustment knob 322. Two sets of mating nuts 311 are coaxially fixed on the side walls of the two cutting blades 31. The two sets of mating nuts 311 are respectively threaded onto the two reverse threads of the bidirectional threaded screw 321. The knob 322 is fixedly mounted on the top of the bidirectional threaded screw 321 so as to synchronously rotate the bidirectional threaded screw 321 to adjust the two cutting blades 31 in opposite directions. The bottom end of the bidirectional threaded screw 321 is mounted on the base 1 through a bearing. The two reverse threads of the bidirectional threaded screw 321 precisely mesh with the mating nut 311 on the side wall of the cutting blade 31. Rotating a single knob 322 drives the two cutting blades 31 to move synchronously towards or away from the cable, achieving synchronous and symmetrical adjustment of the cutting depth. This avoids the problem of inconsistent cutting depths on both sides caused by unilateral adjustment, effectively preventing damage to the conductor due to excessive depth on one side or incomplete cutting due to insufficient depth on the other side. The mechanical characteristics of the threaded drive ensure adjustment accuracy, allowing for fine-tuning of the depth to adapt to the outer layer structure of cables of different thicknesses. At the same time, the self-locking property of the thread can stably lock the adjusted depth position, preventing blade displacement due to vibration or tension during operation. Only a single knob operation is required, eliminating the need to calibrate the two blades separately, simplifying the operation process, lowering the operation threshold, improving the consistency and efficiency of batch wire stripping, and offering a simple, reliable structure with low maintenance costs.

[0034] In another embodiment of the present invention, a limiting groove 11 is fixed to the end of the two cutting blades 31 on the base 1 to restrict the movement direction of the two cutting blades 31. This provides precise guidance and limiting constraints for the cutting blades 31, forcing them to move smoothly only along a preset direction perpendicular to the cable axis. This effectively avoids problems such as blade tilting, misalignment, and offset during adjustment, ensuring that the cutting blades 31 on both sides are always symmetrically distributed, further enhancing the consistency of synchronous adjustment, and ensuring uniform cutting depth and regular cutting trajectory. At the same time, the limiting constraint reduces the shaking of the cutting blades 31 when the cable is pulled out axially, improving the stability of the blade installation and the structural reliability. It avoids incomplete cutting, conductor damage, or accelerated blade wear caused by the displacement of the cutting blades 31, ensuring both wire stripping accuracy and product yield, and extending the service life of the cutting blades 31. This provides reliable structural support for the stable cutting of cables with different wire diameters and multi-layer structures.

[0035] In the above embodiment, each component of the blade cutting depth adjustment part 32 is positioned close to the cable inlet end, and the limiting slide 11 is positioned close to the cable outlet end, so as to pre-cut the cable when it is initially inserted. That is, in order to improve the cutting efficiency and cutting effect of the cable, the above-mentioned arrangement allows the height of the end of the cutting blade 31 close to the cable inlet end to be adjusted first when adjusting the knob 322. Due to the limitation of the limiting slide 11, the other end of the cutting blade 31 will have a delayed adjustment, that is, the cutting blade 31 will be tilted for a period of time, so that its end can cut into the inside of the cable more easily. When the preset length is cut, such as when the cut section reaches the cable outlet end, the cutting blade 31 at the limiting slide 11 can be pressed, so that the entire cutting blade 31 cuts into the conductor inside the cable, so as to facilitate the subsequent continuous cutting process of pulling the cable. By pre-cutting during initial insertion, cutting resistance is significantly reduced, avoiding problems such as jamming, tearing, or blade slippage during initial cutting. When the cutting segment reaches the cable exit end, pressing the blade at the limiting groove allows the entire blade to quickly conform to the cable for a flush cut. This ensures a continuous and uniform circumferential cutting effect when the cable is pulled out axially. Furthermore, the synergy between pre-cutting and flush cutting significantly improves cutting efficiency and cut regularity. It is also compatible with multi-layer and single-protection-layer cables, further enhancing the smoothness and thoroughness of cutting, reducing secondary operations, and balancing ease of operation with wire stripping accuracy.

[0036] In a specific embodiment of the conductive cut depth detection component 4 of the present invention, the conductive cut depth detection component 4 includes a low-voltage power supply module 41, a signal detection module 42, and a signal feedback module 43 connected in series. The input terminal of the low-voltage power supply module 41 is electrically connected to one of the cutting blades, and the output terminal of the signal feedback module 43 is electrically connected to the other cutting blade, so that when the two cutting blades 31 simultaneously contact the internal conductor of the cable, a path is formed. The signal detection module 42 detects the path signal and feeds it back to the user through the signal feedback module 43. The low-voltage power supply module 41 ensures electrical safety during operation and avoids the risk of electric shock. A complete circuit is only formed when both cutting blades 31 simultaneously contact the internal conductor of the cable, effectively eliminating misjudgments caused by accidental contact of a single blade and ensuring the symmetry and accuracy of the cutting depth. The signal detection module 42 captures the circuit signal in real time and provides intuitive feedback to the user through the signal feedback module 43, completely solving the problem of relying on experience to judge the cutting depth in existing technologies. This allows users to quickly know whether the cutting is in place without professional skills, effectively preventing damage to the conductor from excessive cutting or incomplete cutting from insufficient cutting. The overall structure is simple and responsive, and it can work stably without complicated debugging. This not only lowers the operating threshold but also improves the stripping accuracy and work efficiency, providing a reliable detection guarantee for the accurate stripping of various types and multi-layered cables.

[0037] In the above embodiments, the cable includes a conductor and an insulation layer, a shielding layer and a protective layer coaxially sleeved from the inside to the outside. The cutting edges of the two cutting blades 31 are both provided with a preset tilt angle with the cable axis, and the cutting edges of the two cutting blades 31 adopt a stepped cutting edge structure. The stepped cutting edge structure includes a wide cutting edge 312 adapted to cutting the cable protective layer and a narrow cutting edge 313 adapted to cutting the cable shielding layer and insulation layer. The wide blade 312 is specifically designed to adapt to thicker and harder cable protective layers, utilizing a larger cutting contact area to achieve efficient and thorough cutting, avoiding jamming or tearing of the protective layer during cutting. The narrow blade 313 precisely matches thinner shielding and insulation layers, achieving precise entry through concentrated cutting force. This ensures effective shearing of the shielding wires, avoids blade entanglement, and prevents damage to the inner conductor caused by over-cutting of the insulation layer. The preset tilt angle of the blade and the axial pull-out cutting action work together to increase cutting friction and shearing efficiency, making the cutting process of multi-layered cables smoother. Specifically, the tilt angle can be preset to 30°. It can adapt to different material layers of cables from the outer to the inner layers without changing the blade, significantly improving the equipment's adaptability and cutting accuracy for multi-layered cables, while simplifying the operation process and ensuring thorough separation of each layer after stripping, with no damage to the conductor.

[0038] In the above embodiment, the signal detection module 42 has two current detection thresholds corresponding to the current when the cutting blade 31 contacts the cable's shielding layer and conductor, respectively. The signal feedback module 43 is a multi-color indicator light, which displays and distinguishes the conduction state of different current magnitudes through different colored light signals. This achieves accurate layer identification of the multi-layer conductive structure of the cable, completely solving the problem of misjudgment caused by the inability of existing technologies to distinguish the contact state between the shielding layer and the conductor. The multi-color light signal intuitively reflects the cutting progress of the blade, i.e., not contacting the conductive layer → contacting the shielding layer → contacting the conductor. Users can quickly know the cutting depth without relying on experience or complex observation, effectively avoiding insufficient or excessive cutting due to misjudgment. The dual-threshold detection logic adapts to the differences in conductivity characteristics of multi-layer cables, and the signal feedback is sensitive and accurate. This not only lowers the operation threshold, allowing novices to efficiently and accurately strip the wire, but also improves the adaptability to cables with shielding layers, ensuring that the shielding layer is completely cut off and the conductor is intact after stripping, further ensuring the reliability and efficiency of subsequent line connections.

[0039] Specifically, the low-voltage power supply module 41 is a miniaturized, low-power low-voltage power supply that can use a 3V button battery or a 3.7V micro lithium battery to ensure stable and safe output voltage; the signal detection module 42 is a dual-channel current sensor with preset shielding layer conduction current threshold and conductor conduction current threshold; the signal feedback module 43 is a multi-color indicator light, specifically a three-color LED indicator light, including yellow, green and red, where yellow light represents contact with the shielding layer, green light represents contact with the conductor, and red light represents over-cutting, to directly feedback the cutting progress.

[0040] In addition, when the target cable is a cable with only a protective layer, it is also applicable to this manual wire stripping device. The conductive cutting depth detection component 4 accurately feeds back the cutting status through a single conductor contact threshold. The multi-color indicator light intuitively indicates whether the conductive layer has not been contacted or the conductor has been contacted, effectively preventing excessive cutting that could damage the conductor or insufficient cutting that could lead to incomplete cutting.

[0041] The working principle of the simple manual wire stripping device of the present invention is as follows: Cable pretreatment and pre-fixation: The user places the cable between the two openings of the first V-shaped plate of the cable pre-insertion structure and tightens the screws to achieve initial centering and fixation of the cable, so that the cable axis remains coaxial with the cutting trajectory of the subsequent cutting blade.

[0042] Precise cable clamping and positioning: Place the pre-fixed cable pre-insertion structure along with the cable between the two second V-shaped plates of the cable clamping structure. Rotate the control handle to drive the adjusting screw, which moves the sliding side second V-shaped plate towards the fixed side until the two plates tightly clamp the cable. The stop plate on the fixed side second V-shaped plate forms an axial stop support for the pre-insertion structure, preventing back-and-forth movement or left-and-right displacement during operation, and ensuring that the cable is stable in position and free from radial deformation during the cutting process.

[0043] Adjusting the cutting blade depth and performing pre-cutting: Rotate the knob on the blade cutting depth adjustment unit to drive the bidirectional threaded screw to rotate. Through the cooperating nut, it drives two symmetrically distributed cutting blades to synchronously approach the cable in opposite directions, with the end of the cutting blade closest to the cable inlet pre-tilted to pre-cut the cable until the cut portion is pulled to the cable outlet. Press the other end of the cutting blade to make it slide along the limit groove until it is flush with the other end, completing the pre-cutting process. At this time, the cutting edge of the cutting blade abuts against the internal conductor of the cable. During pre-cutting and cutting, the low-voltage power supply module continuously provides safe low-voltage power. If the blade contacts the cable shielding layer, the two blades form a circuit with the shielding layer. The detection module captures the corresponding shielding layer conduction current signal, triggering the multi-color indicator light to light up yellow, indicating that the protective layer has been cut through. Continue fine-tuning until the blade contacts the conductor. The detection module captures the conductor conduction current signal, and the green light lights up, indicating that the cutting depth is up to standard. The user stops adjusting to avoid over-cutting. When the red light lights up, it indicates that the cutting depth is too deep, reminding the user to continue adjusting the cutting depth.

[0044] Axial pull-cutting operation: The user holds the exposed end of the cable and pulls the cable out at a constant speed along the cable axis. At this time, the two symmetrically distributed cutting blades work together through the stepped blade structure and the preset tilt angle. The wide blade section efficiently cuts the outer protective layer of the cable, while the narrow blade section precisely cuts the shielding layer and insulation layer. No rotating equipment is required. The circular cut of the outer structure of the cable can be completed by only axial relative movement. The balanced cutting force generated by symmetrical cutting avoids the cable being deviated by force, ensuring a neat cut.

[0045] Real-time monitoring of cutting status: During the pulling and cutting process, the conductive cutting depth detection component works continuously. If the blade deviates due to uneven cable material or slight shaking during operation, the detection module will capture the change in current signal in real time. If the current exceeds the conductor conduction threshold, the red light will illuminate to prompt the user to adjust the depth in time. If the current does not reach the corresponding threshold, the indicator light will not provide corresponding feedback. The user can fine-tune the blade depth or speed up the pulling speed to ensure that the outer structure is cut thoroughly.

[0046] In summary, this invention solves the technical problems of existing manual wire stripping equipment, such as the lack of accurate identification of multi-layer conductive structures in the cutting depth, poor clamping adaptability leading to cable misalignment and injury, asynchronous adjustment of cutting blades and inability of the cutting edge to adapt to multi-layer structures, high operating threshold and limited adaptability. It achieves precise cutting of the outer layer structure of the cable by axial pulling out, which can adapt to various cables of different diameters and with or without shielding layers, ensuring stable clamping without deviation and neat and uniform cutting cuts. It can also intuitively distinguish the cutting progress to avoid conductor damage or incomplete cutting, significantly reducing the operating threshold and improving wire stripping accuracy and work efficiency. At the same time, it has the advantages of simple structure, portability and reliability, and low maintenance cost, fully meeting the precise wire stripping needs of various scenarios such as personal repair, batch operation, and confined space.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
