Description

Technical Field

[0001] This invention relates to the field of wire insulation stripping technology, and in particular to a detachable cutter head and an adjustable inner and outer wire sheath simultaneous stripping pliers. Background Technology

[0002] Wire strippers are commonly used tools in communication cable processing to remove the outer or inner insulation of wires. In existing technology, wire strippers typically employ a head structure with blades of different sizes, allowing for layered stripping by manually selecting the blade that matches the wire diameter.

[0003] For example, existing technology proposes a typical wire stripper structure, including an upper clamp arm and a lower clamp arm, with multiple blades at the front end of the clamp arms for gripping and cutting the wire sheath. When stripping wires with multiple layers of insulation, such as coaxial cables, the operator must first place the wire into the blades corresponding to the diameter of the outer sheath, squeeze the clamp arms to cut the outer sheath, and then pull out the wire to peel off the outer sheath; then, the same wire is placed into the blades corresponding to the diameter of the inner sheath and the above operation is repeated to peel off the inner sheath. This technical solution has the following drawbacks: 1. Only one layer of sheath can be stripped at a time, making it impossible to strip multiple layers of sheath simultaneously. The operation is cumbersome and inefficient. 2. Because the blade size is fixed, it has poor adaptability to wires of different diameters. If the blade is not selected properly, it can easily lead to damage to the wire core or incomplete stripping of the wire sheath. 3. The inner and outer sheaths are stripped in two stages. The reserved length of the inner sheath is not easy to control, which can easily lead to inconsistent lengths and affect the wiring quality. Summary of the Invention

[0004] This invention provides a detachable blade and an adjustable inner and outer sheath simultaneous stripping pliers, which can adapt to different wire diameters, support simultaneous stripping of inner and outer sheaths, and are easy to operate, thereby improving stripping efficiency and quality, and solving the technical problems of existing pliers that cannot simultaneously strip multiple layers of wire sheaths, have poor wire diameter adaptability, and low operating efficiency.

[0005] According to one aspect of the present invention, a detachable cutter head is provided, comprising a cutter head seat and a blade. The blade is rotatably arranged on the cutter head seat with a portion of the blade exposed. The edge of the blade is provided with a plurality of arc-shaped cutting edges with different radial dimensions, and the plurality of arc-shaped cutting edges are arranged at intervals along the circumference of the blade. A first elastic positioning component is provided between the blade and the cutter head seat. The first elastic positioning component is elastically compressed when the blade is rotated for adjustment and resets and pops out after the blade is rotated for adjustment to position the blade. The first elastic positioning component is matched with the arc-shaped cutting edges. A double slide rail sliding structure is provided on the cutter head seat. The double slide rail sliding structure is used to cooperate through two parallel slide rails to achieve sliding adjustment and fix the position after sliding adjustment.

[0006] Furthermore, the first elastic positioning component includes a first mounting hole, a first spring, and a first round-headed pin. The first mounting hole is formed on the cutter head seat, the first round-headed pin is slidably arranged in the first mounting hole, and the first spring is fixed between the first round-headed pin and the first mounting hole. The center hole of the blade is rotatably connected to the cutter head seat through a rotating pin. The blade has multiple first positioning holes, which are evenly spaced along the circumference of the blade. Each arc-shaped cutting edge corresponds to a first positioning hole in the radial direction of the blade. The first elastic positioning component matches the circumference of the arrangement of the first positioning holes of the blade.

[0007] Furthermore, a handle is provided on the blade plate surface, and an avoidance groove is provided on the blade holder, with the movement trajectory of the handle within the area of ​​the avoidance groove.

[0008] Furthermore, the dual-rail sliding structure includes a slide rod positioning assembly disposed at the bottom of the cutter head seat for sliding engagement and positioning after sliding adjustment. The end of the slide rod positioning assembly is configured as a second elastic positioning assembly. The second elastic positioning assembly is compressed into the base of the slide rod positioning assembly when the slide rod positioning assembly is slidably adjusted and then reset and popped out after sliding adjustment to position the slide rod positioning assembly and the cutter head seat, thus forming the slide rail sliding structure and the positioning structure.

[0009] Furthermore, the slide bar positioning assembly includes a cylindrical tube vertically arranged at the bottom of the cutter head seat, and the second elastic positioning assembly includes a second mounting hole, a second spring, and a second round-headed pin. The second mounting hole is opened at the end of the cylindrical tube, the second round-headed pin is slidably arranged in the second mounting hole, and the second spring is fixed between the second round-headed pin and the second mounting hole.

[0010] Furthermore, the dual-rail sliding structure includes a sliding buckle disposed on the cutter head seat. The sliding buckle is used to engage with the slide groove and constitutes the slide rail sliding structure.

[0011] According to another aspect of the present invention, an adjustable inner and outer sheath synchronous stripping pliers is also provided, including the aforementioned detachable cutter disc.

[0012] Furthermore, it also includes a first jaw and a second jaw arranged in a scissor-like configuration. The first jaw of the first jaw and the second jaw of the second jaw are arranged opposite each other. The first jaw is provided with a plurality of first arc-shaped cutting edges, the radial dimensions of which are arranged to increase or decrease sequentially. The first arc-shaped cutting edges on the first jaw and the second arc-shaped cutting edges on the second jaw are arranged in a one-to-one correspondence with each other in terms of their radial dimensions. Both the first jaw and the second jaw are provided with double track grooves for mounting a detachable cutter head, and the double track grooves on the first jaw and the double track grooves on the second jaw are arranged in a corresponding manner.

[0013] Furthermore, the dual-track groove includes a first groove unit and a second groove unit, which are located on different planes, thus forming a three-dimensional multi-track sliding structure with the detachable cutter head.

[0014] Furthermore, the detachable cutter head is mounted on the first clamp arm, and the first groove unit is connected to the slide rod positioning assembly of the detachable cutter head, so that the arc-shaped cutting edge of the detachable cutter head is arranged parallel to the first arc-shaped cutting edge. The first groove unit includes a groove rail and a third positioning hole, and the third positioning hole is arranged one-to-one with the first arc-shaped cutting edge. The second groove unit is engaged with and slidably engaged with the sliding buckle of the detachable cutter head; or the detachable cutter head is mounted on the second clamp arm, and the first groove unit is connected to the slide rod positioning assembly of the detachable cutter head, so that the arc-shaped cutting edge of the detachable cutter head is arranged parallel to the second arc-shaped cutting edge. The first groove unit includes a groove rail and a third positioning hole, and the third positioning hole is arranged one-to-one with the second arc-shaped cutting edge. The second groove unit is engaged with and slidably engaged with the sliding buckle of the detachable cutter head.

[0015] The present invention has the following beneficial effects: 1. Improved adaptability and switching efficiency of the tool to multiple wire diameters: The blade edge is circumferentially spaced with multiple arc-shaped cutting edges of different radial sizes. By rotating the blade, the required cutting edge can be quickly rotated to the working position. This integrated design of one blade with multiple cutting edges replaces the traditional operation of changing the entire pliers head or repeatedly aligning between different cutting edges, making the detachable blade head adaptable to the cutting needs of wires of various diameters. This significantly enhances the versatility of the tool. Operators do not need to prepare or change multiple tools; they can switch cutting edges simply by rotating the blade, thus improving work efficiency.

[0016] 2. Ensure positioning accuracy and operational stability during cutting: The first elastic positioning component is matched with the arc-shaped cutting edge of each blade. When the blade is rotated to bring a certain cutting edge to the working position, the elastic positioning component will reset, pop out, and lock into position, providing clear tactile feedback to the operator and locking the blade. This mechanism effectively prevents problems such as inaccurate cutting position, incomplete stripping of wire insulation, or damage to the wire core caused by accidental rotation of the blade during the cutting process, thereby ensuring the accuracy and consistency of each cut and improving processing quality and reliability.

[0017] 3. Achieve precise fine-tuning and stable fixation of the cutter head's working position: The double slide rail structure at the bottom of the cutter head base allows for smooth and linear displacement adjustment along two parallel rails simultaneously. This structure provides a basis for combining two cutter heads to achieve functional expansion (such as mounting them on wire strippers to achieve synchronous stripping of inner and outer wire sheaths through cooperation with the wire strippers). After adjustment, the locking mechanism ensures that the cutter head will not shift when cutting under force, guaranteeing the achievement of high-precision machining requirements.

[0018] 4. Enhanced tool maintenance convenience and modularity: The entire cutter head adopts a detachable design. When the blades wear out or a special cutter head needs to be replaced for a specific cable, the module can be quickly replaced, which greatly improves the maintainability and service life of the tool and gives the tool greater functional flexibility.

[0019] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0024] like Figure 1As shown, the detachable cutter head of this embodiment includes a cutter head seat 100 and a blade 200. The blade 200 is rotatably arranged on the cutter head seat 100 with a portion of the blade 200 exposed. The edge of the blade 200 is provided with a plurality of arc-shaped cutting edges 201 with different radial dimensions, and the plurality of arc-shaped cutting edges 201 are arranged at intervals along the circumference of the blade 200. A first elastic positioning component 300 is provided between the blade 200 and the cutter head seat 100. The first elastic positioning component 300 is used to elastically compress when the blade 200 is rotated and adjusted, and to reset and pop out after the blade 200 is rotated and adjusted to position the blade 200. The first elastic positioning component 300 is matched and arranged with the arc-shaped cutting edges 201. A double slide rail sliding structure 400 is provided on the cutter head seat 100. The double slide rail sliding structure 400 is used to cooperate through two parallel slide rails to realize sliding adjustment, and to fix the position after sliding adjustment. This invention features a detachable cutter head with multiple radially spaced arc-shaped cutting edges 201 of varying sizes along the circumferential edge of the blade 200. By rotating the blade 200, the desired cutting edge can be quickly rotated to the working position. This integrated design of multiple cutting edges replaces the traditional wire stripper's requirement to replace the entire pliers head or repeatedly align different cutting edges, allowing the detachable cutter head 10 to adapt to the cutting needs of various wire diameters. This significantly enhances the tool's versatility, eliminating the need for operators to prepare or change multiple tools; a simple rotation allows for cutting edge switching, improving work efficiency. A first elastic positioning component 300 is matched to each arc-shaped cutting edge 201. When rotating the blade 200 to bring a cutting edge to the working position, the elastic positioning component resets, pops out, and engages, providing clear tactile feedback to the operator and locking the blade 200. This mechanism effectively prevents problems such as inaccurate cutting position, incomplete wire stripping, or damage to the wire core caused by accidental rotation of the blade 200 during cutting, thus ensuring the accuracy and consistency of each cut and improving processing quality and reliability. The double-slide rail sliding structure 400 at the bottom of the cutter head holder 100 allows for smooth, linear displacement adjustment along two parallel rails simultaneously. This structure provides the basis for combining two cutter heads to achieve functional expansion (such as mounting them on wire strippers to simultaneously strip inner and outer wire sheaths through coordinated action). Once adjusted, the locking mechanism ensures that the cutter head will not shift during force cutting, guaranteeing the achievement of high-precision machining requirements. The entire cutter head adopts a detachable design, allowing for quick module replacement when the blade 200 wears or when a dedicated cutter head is needed for specific cables. This greatly improves tool maintainability and lifespan, and gives the tool greater functional flexibility.The detachable cutter head 10 of this invention, through the coordinated design of several core elements—integrating multi-specification curved cutting edges 201 on the blade 200, setting up elastic positioning components, and integrating a double slide rail structure in the cutter head seat 100—achieves improved cutting adaptability, ensures positioning accuracy, enables precise position fine-tuning, and enhances modularity. It solves the technical problems existing in the prior art, such as poor tool versatility, low operating efficiency, easy damage to wire cores, and difficulty in controlling stripping length, and provides an efficient, accurate, and reliable wire stripping solution.

[0025] like Figure 1As shown, in this embodiment, the first elastic positioning component 300 includes a first mounting hole 301, a first spring 302, and a first round-headed pin 303. The first mounting hole 301 is formed on the cutter head seat 100, the first round-headed pin 303 is slidably arranged in the first mounting hole 301, and the first spring 302 is fixed between the first round-headed pin 303 and the first mounting hole 301. The center hole 202 of the blade 200 is rotatably connected to the cutter head seat 100 through a rotating pin 203. The blade 200 has a plurality of first positioning holes 204, which are evenly spaced along the circumference of the blade 200. Each arc-shaped cutting edge 201 corresponds to a first positioning hole 204 in the radial direction of the blade 200. The first elastic positioning component 300 matches the circumference of the arrangement of the first positioning holes 204 of the blade 200. When the blade 200 is rotated, the spherical end of the first round-headed pin 303 slides along the bottom surface of the blade 200 and remains in contact under the continuous action of the first spring 302. When the blade 200 rotates to align with a certain first positioning hole 204 and the first round-headed pin 303, the first round-headed pin 303 quickly embeds into the first positioning hole 204 under the push of the first spring 302. This process produces a clear "click" sound and a tactile feedback, providing the operator with clear tactile and auditory feedback, indicating that the curved cutting edge 201 has accurately reached the predetermined working position. This mechanical self-locking effect can effectively prevent the blade 200 from unexpectedly deflecting due to vibration or force in subsequent cutting operations, thereby ensuring the accuracy and consistency of the selected curved cutting edge 201 relative to the wire, and avoiding the risk of inaccurate cutting depth, incomplete wire stripping, or damage to the wire core caused by the displacement of the blade 200. Multiple first positioning holes 204 are evenly spaced along the circumference of the blade 200, and each first positioning hole 204 corresponds radially to a specific arc-shaped cutting edge 201. This one-to-one correspondence allows the operator to quickly and linearly switch between different sizes of arc-shaped cutting edges 201 with a simple rotation action. The selection function of the arc-shaped cutting edge 201 is highly integrated into a single rotating blade 200, replacing the traditional tool operation that requires changing accessories or repeated calibration. Users do not need to visually align precisely; they can quickly and accurately switch the target arc-shaped cutting edge 201 to the working position by feel alone, simplifying the operation steps and improving the efficiency of wire stripping preparation. The first elastic positioning component 300 (including the first round-headed pin 303 and the first spring 302) is built into the first mounting hole 301 of the cutter head holder 100. It has a compact structure, does not occupy extra space, and has high mechanical strength and wear resistance. The component is hidden inside the cutter head holder 100 and is protected from damage by external forces or accumulation of dirt. Even if wear occurs after long-term use, the first spring 302 or the first round-headed pin 303 can be easily replaced, making it highly maintainable and helping to extend the service life of the entire cutter head.The first elastic positioning component 300 provides a reliable indexing and positioning function, clear gear feedback and efficient operation experience for the rotatable multi-bladed blade 200 through the elastic engagement mechanism of the first round-headed pin 303 and the first mounting hole 301, ensuring that the wire stripper can achieve fast and accurate wire diameter matching and guarantee the stability of each cutting operation.

[0026] like Figure 1 As shown, in this embodiment, a handle 205 is provided on the plate surface of the blade 200, and a clearance groove 101 is provided on the cutter head seat 100. The movement trajectory of the handle 205 is within the area of ​​the clearance groove 101. The handle 205 is fixedly set on the plate surface of the blade 200, providing the operator with a protruding structure specifically for applying force to rotate the blade 200. The clearance groove 101 correspondingly provided on the cutter head seat 100 has a contour that perfectly matches the movement trajectory formed by the handle 205 when the blade 200 rotates, allowing the operator to easily and effortlessly turn the handle 205 to rotate the blade 200. The clearance groove 101 provides dedicated physical space for the entire movement of the handle 205, ensuring that it will not collide or rub against the body of the cutter head seat 100 during 360-degree rotation, avoiding movement interference between components, ensuring smooth and unobstructed rotation adjustment of the blade 200, improving the operating experience, and reducing the risk of component wear caused by jamming or friction, thereby enhancing the stability and service life of the entire cutter head structure. The handle 205 serves as a prominent physical marker on the blade 200, and its position is directly related to the currently working curved cutting edge 201. The operator can quickly and intuitively determine the size of the currently selected curved cutting edge 201 by observing the position of the handle 205, without needing to closely observe the scratches or markings on the blade 200. This improves the recognition speed and accuracy of switching the curved cutting edge 201, effectively preventing poor cutting that may result from misselecting the curved cutting edge 201, and further enhancing the reliability of overall operating efficiency.

[0027] like Figure 1As shown, in this embodiment, the dual slide rail sliding structure 400 includes a slide rod positioning component 401 disposed at the bottom of the cutter head seat 100 for sliding engagement and positioning after sliding adjustment. The end of the slide rod positioning component 401 is configured as a second elastic positioning component 402. The second elastic positioning component 402 is compressed into the base of the slide rod positioning component 401 when the slide rod positioning component 401 is slidably adjusted and is reset and popped out after sliding adjustment to position the slide rod positioning component 401 and the cutter head seat 100, thus forming a slide rail sliding structure and a positioning structure. The slide bar positioning assembly 401 constitutes one of the main components of the double slide rail sliding structure 400, ensuring that the cutter head holder 100 can slide smoothly along a precise track. During sliding adjustment, the second elastic positioning assembly 402 is compressed into the base to overcome positioning resistance. When sliding to the target position (such as the preset positioning hole), the second elastic positioning assembly 402 is reset and ejected under the action of spring force, embedding into the positioning point. This design makes the adjustment process smooth and has a clear sense of gear position, realizing stepless or stepped precise position adjustment. After locking, the mechanism can effectively resist the radial force generated when cutting the wire sheath, preventing the blade from... Unexpected displacement of the disc during operation ensures the precision and consistency of the stripping length of the inner and outer sheaths, determined by the disc spacing, thus solving the problem of difficult stripping length control. This sliding structure allows for adjustment of the discs, changing the correspondence between the selected cutting edges on the two discs to directly correspond to the precise dimensions of the sheath to be stripped, forming the basis for achieving "simultaneous stripping of inner and outer sheaths in a single operation." The operator only needs to pre-adjust and set the settings according to the wire specifications to ensure that the sheath is simultaneously cut by the arc-shaped cutting edges 201 on both discs when the clamping arms are engaged, improving stripping efficiency. The dual-rail parallel layout, compared to a single rail, allows for better, smoother, and more efficient sliding adjustment, as well as balancing the torque generated during cutting. This prevents the disc holder 100 from tilting or jamming, improving the rigidity and movement stability of the disc under stress. It ensures concentric clamping of the wire by the upper and lower arc-shaped cutting edges 201, resulting in uniform cutting depth and further preventing damage to the wire core due to skewing, thus improving processing quality.

[0028] like Figure 1As shown, in this embodiment, the slide bar positioning assembly 401 includes a cylindrical tube 4011 vertically arranged at the bottom of the cutter head seat 100, and the second elastic positioning assembly 402 includes a second mounting hole 4021, a second spring 4022, and a second round-headed pin 4023. The second mounting hole 4021 is opened at the end of the cylindrical tube 4011, the second round-headed pin 4023 is slidably arranged in the second mounting hole 4021, and the second spring 4022 is fixed between the second round-headed pin 4023 and the second mounting hole 4021. The cylindrical tube 4011 serves as a sliding rod, and its end integrates a second elastic positioning component 402 consisting of a second round-headed pin 4023, a second spring 4022, etc. When the cutter head seat 100 slides along the double slide rails, the end of the second round-headed pin 4023 interacts with the positioning hole on the slide rail or mounting base. When sliding, the second round-headed pin 4023 is pressed down, and the second spring 4022 is compressed. When reaching the target position, the second round-headed pin 4023 springs into the positioning hole under the action of the spring force. This mechanism provides clear tactile and audible feedback for sliding adjustment, enabling the operator to accurately perceive the positioning point, thereby achieving rapid and accurate setting of the cutter head spacing. The mechanical self-locking formed after the second round-headed pin 4023 enters the positioning hole can effectively prevent the cutter head from accidentally sliding under the radial force or vibration of the subsequent cutting wire, ensuring the absolute stability of the preset cutter head's arc-shaped cutting edge 201 during operation, thereby ensuring machining accuracy. The second elastic positioning component 402 is directly integrated into the end of the cylindrical tube 4011, which serves as the sliding rod, in a coaxial integrated design. This highly integrates the sliding guidance function and the position locking function into a compact component, avoiding the need for additional complex locking mechanisms on the outside. This makes the overall structure more compact and simple, saving installation space. At the same time, the force path is direct. The cutting force is transmitted through the cutter head seat 100 to the vertically arranged cylindrical tube 4011 (sliding rod), and then through the cylindrical tube 4011 (sliding rod) to the clamp body. The force flow path is clear and stable, which helps to improve the structural rigidity and durability of the entire component.

[0029] like Figure 1As shown, in this embodiment, the dual-rail sliding structure 400 includes a sliding buckle 102 disposed on the cutter head seat 100. The sliding buckle 102 is used to engage with the slide groove and form a sliding rail structure. The sliding buckle 102 disposed on the cutter head seat 100 is used to form a snap-fit ​​with the corresponding slide groove on the wire stripper body. During installation, the cutter head seat 100 can be conveniently installed onto the pliers body by the elastic deformation or alignment of the sliding buckle 102. This "buckle-slide groove" structure realizes the quick assembly and disassembly of the cutter head, improving the convenience of tool assembly and maintenance. Once snapped in, the engagement of the sliding buckle 102 and the slide groove forms a precise sliding pair and constitutes another slide rail body of the dual-rail sliding structure 400, ensuring that the cutter head seat 100 can slide smoothly along a predetermined trajectory, providing a basis for subsequent spacing adjustment, and preventing the cutter head from accidentally falling off the pliers body during use, thus ensuring the reliability of operation. Optionally, the sliding buckle 102 can connect the cutter head seat 100 to the sliding groove on the pliers body at multiple points, effectively distributing the force generated when cutting the wire sheath from the cutter head seat 100 to the pliers body through the contact surfaces of multiple sliding buckles 102. This connection method increases the rigidity of the structure and reduces possible shaking or deformation under force, thereby ensuring precise alignment and uniform force application of the upper and lower blades to the wire, helping to improve cutting quality and avoid uneven cutting depth or wire core damage caused by structural instability. The sliding buckle 102 serves to quickly install the cutter head onto the sliding groove of the wire stripper body and forms another basic interface for sliding engagement. After the sliding buckle 102 is installed, the slide rod positioning assembly 401 (cylindrical cylinder 4011) provides the main sliding guide and load-bearing structure. During sliding adjustment, the second elastic positioning assembly 402 integrated at the end of the slide rod positioning assembly 401 (cylindrical cylinder 4011) provides the stop feel and locking function. These parts constitute a complete functional chain, and the sliding buckle 102 enables convenient initial adjustment. During initial installation and connection, the slide bar positioning assembly 401 ensures smooth and precise sliding, while the second elastic positioning assembly 402 achieves precise position setting and secure locking. Through their coordinated work, the cutter head can be easily installed, disassembled, and maintained, and the overall structure can be made stable and reliable during operation. The sliding buckle 102 ensures the initial alignment and basic constraint of the cutter head seat 100 and the clamp body connection, while the slide bar positioning assembly 401 provides a longer guide distance and stronger torque resistance on this basis. The two complement each other and jointly ensure the smoothness and stability of the sliding process.When cutting the wire sheath, the force acting on the blade 200 is transmitted to the cutter head seat 100. Then, through the connection point of the sliding buckle 102 and the two fulcrums of the slide rod positioning component 401, the force is distributed and transmitted to the wire stripper body. This multi-point support structure combining "point and line" forms a stable statically determinate or hyperstatically indeterminate force flow transmission path, which effectively improves the rigidity and stability of the entire cutter head assembly under stress and avoids the slight deformation or shaking that may occur due to a single support point. This structural rigidity is the key to ensuring that the upper and lower blades are accurately aligned, achieving a clean and neat cut without damaging the wire core.

[0030] like Figure 2 As shown, the adjustable inner and outer sheath synchronous wire stripper of this embodiment includes the aforementioned detachable blade disc 10. Two detachable blade discs 10 are mounted side-by-side on the wire stripper. By rotating the blades 200 on each detachable blade disc 10, the arc-shaped cutting edge 201 matching the diameter of the inner and outer sheaths of the wire can be independently selected. Through the double-slide rail sliding structure 400 at the bottom of the blade disc base 10, the dimensional matching relationship between the two detachable blade discs 10 can be precisely adjusted, directly corresponding to the thickness of the inner or outer sheath. During operation, the wire is simultaneously placed between the preset detachable blade disc 10 and the jaws of the wire stripper. A single clamping of the jaws completes the synchronous cutting of the inner and outer sheaths. Then, pulling the wire strips it synchronously. This changes the cumbersome process of traditional technology, which requires two operations and two pulls, halving the wire stripping steps and significantly improving efficiency. The first elastic positioning component 300 on each detachable cutter head 10 ensures the accurate and stable working position of the selected arc-shaped cutting edge 201, preventing slippage and displacement during cutting. The double slide rail sliding structure 400 and its second elastic positioning component 402 ensure that the distance between the detachable cutter head 10 and the wire stripper jaws remains locked under force. The synergistic effect of the sliding buckle 102 and the slide rod positioning component 401 ensures the overall structural rigidity of the cutter head. These characteristics work together to ensure precise and controllable cutting depth, effectively avoiding damage to the wire core or incomplete stripping. At the same time, the stripping length is precisely set by the mechanical structure, with extremely high consistency, solving the problem of inconsistent lengths caused by manual operation, and significantly improving the processing quality and reliability of the wire terminals. Each detachable cutter head 10 is itself an integrated module of a multi-specification curved cutting edge 201. The curved cutting edge 201 can be independently adjusted and matched with the jaws of the wire strippers by sliding, allowing the wire stripper to flexibly adapt to wires with various combinations of inner and outer diameters. One tool can replace multiple traditional fixed-specification wire strippers, making it extremely versatile. In addition, the detachable design of the detachable cutter head 10 allows for quick replacement of individual modules after the cutting edge wears, reducing long-term usage costs and extending the tool's lifespan.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, it also includes a first jaw 20 and a second jaw 30 arranged in a scissor-like manner. The first jaw of the first jaw 20 and the second jaw of the second jaw 30 are arranged opposite to each other. The first jaw is provided with a plurality of first arc-shaped cutting edges 21. The radial dimensions of the plurality of first arc-shaped cutting edges 21 are arranged to increase or decrease sequentially. The first arc-shaped cutting edges 21 on the first jaw and the second arc-shaped cutting edges 31 on the second jaw are arranged in a one-to-one correspondence with matching radial dimensions. Both the first jaw and the second jaw are provided with double track grooves for assembling the detachable cutter head 10. The double track grooves on the first jaw and the double track grooves on the second jaw are arranged in a corresponding manner. The first and second jaws not only have double track slots for mounting the detachable cutter head 10, but also integrate multiple first arc-shaped cutting edges 21 and second arc-shaped cutting edges 31 with sequentially varying radial dimensions, making the jaws themselves a complete traditional wire stripping unit. When performing routine single-layer wire stripping or processing wires that do not require simultaneous stripping, the operator can directly use the inherent first arc-shaped cutting edges 21 and second arc-shaped cutting edges 31 on the jaws without installing the detachable cutter head 10. When processing multi-layered wires such as coaxial cables and pursuing high efficiency, the detachable cutter head 10 can be installed in the track slots, giving one tool both the simplicity and reliability of traditional wire strippers and the high efficiency and precision of advanced simultaneous wire strippers. This allows for flexible and rapid switching between two working modes, greatly expanding the tool's applicable scenarios and functional range. The scissor-type jaw arm structure provides a stable and ergonomic force application method. The double track grooves corresponding to the first and second jaws form a precise fit with the double slide rail sliding structure 400 (including the sliding buckle 102 and the slide rod positioning component 401) at the bottom of the cutter head 100, providing guidance and support for the detachable cutter head 10 across the entire jaw width. This "double track groove-double slide rail" fit structure ensures that the upper and lower detachable cutter heads 10 can always maintain precise alignment during the clamping process, avoiding tilting or misalignment that may occur due to single-point support. This provides a fundamental guarantee for the precise and concentric cutting of the arc-shaped cutting edge 201 on the detachable cutter head 10, which is the key to the synchronous wire stripping function without damaging the wire core. The lever principle of the scissor-type jaw arm ensures that the applied force is sufficient to complete the cutting action.The inherent first arc-shaped cutting edge 21 and second arc-shaped cutting edge 31 on the first and second jaws are suitable for quick and simple wire stripping tasks; while the detachable cutter head 10 is specialized for complex synchronous and fixed-length wire stripping tasks. For simple tasks, the inherent first arc-shaped cutting edge 21 and second arc-shaped cutting edge 31 are faster to operate; for complex tasks, the detachable cutter head 10 is more efficient and of higher quality. The two structures complement each other, allowing the tool to easily cope with various complex work requirements. In addition, the presence of the inherent first arc-shaped cutting edge 21 and second arc-shaped cutting edge 31 also means that even in the normal state of not using the detachable cutter head 10, the tool can still be used normally as a full-function traditional wire stripper, improving the tool's practicality and reliability.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the dual-track groove includes a first groove unit 40 and a second groove unit 50. The first groove unit 40 and the second groove unit 50 are located on different planes, thus forming a three-dimensional multi-slide rail sliding structure with the detachable cutter head 10. The first groove unit 40 and the second groove unit 50 are located on different planes, and there is a vertical height difference between their mating points with the corresponding sliding components (sliding buckle 102 and slide rod positioning assembly 401) on the detachable cutter head 10. This layout forms a three-dimensional, non-coplanar constraint structure. This three-dimensional multi-slide rail sliding structure can effectively resist the lateral force or torsional torque (overturning torque) generated when the clamping arm cuts the wire sheath. Compared with the design where all slide rails are on the same plane, this staggered layout greatly enhances the overall rigidity and stability of the detachable cutter head 10 during sliding and operation, preventing it from shaking, tilting or jamming, and providing a mechanical guarantee beyond the planar guide rail for high-precision centering cutting of the upper and lower blades. Multiple constraint points not on the same plane collectively limit the motion freedom of the detachable cutter head 10, allowing it to slide only along a preset, unique spatial trajectory (i.e., a straight line). This makes the sliding process smoother and more precise, reduces backlash, and ensures that the relative positional relationship of the two detachable cutter heads 10 remains constant under the force of the clamping arms after adjustment. This guarantees the accuracy of the inner and outer wire stripping length determined by the spacing. Arranging the track grooves on different planes allows for more rational use of the limited space thickness of the jaws. This three-dimensional layout allows for the integration of more complex and stable guiding mechanisms within the limited jaw structure, avoiding interference or strength reduction caused by stacking all structures on the same level. This facilitates tool miniaturization and functional integration. The three-dimensional multi-slide rail sliding structure, composed of the first groove unit 40 and the second groove unit 50 located on different planes, enhances the overall rigidity, motion stability and torque resistance of the detachable cutter head 10 after installation by establishing a three-dimensional, multi-point spatial constraint. This ensures that the wire stripper can maintain precise blade alignment and stable locking under high-load cutting action, thereby achieving high-quality synchronous wire stripping function.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the detachable cutter head 10 is mounted on the first clamp arm 20. The first groove unit 40 is connected and engaged with the slide rod positioning assembly 401 of the detachable cutter head 10, so that the arc-shaped cutting edge 201 of the detachable cutter head 10 is arranged parallel to the first arc-shaped cutting edge 21. The first groove unit 40 includes a groove rail 41 and a third positioning hole 42. The third positioning hole 42 is arranged one-to-one with the first arc-shaped cutting edge 21. The second groove unit 50 is engaged with the sliding buckle 102 of the detachable cutter head 10 and slides... The first groove unit 40 is connected to the slide rod positioning assembly 401 of the detachable cutter head 10, and the arc-shaped cutting edge 201 and the second arc-shaped cutting edge 31 of the detachable cutter head 10 are arranged in parallel. The first groove unit 40 includes a groove rail 41 and a third positioning hole 42. The third positioning hole 42 and the second arc-shaped cutting edge 31 are arranged in a one-to-one correspondence. The second groove unit 50 is engaged with the sliding buckle 102 of the detachable cutter head 10 and slides in cooperation. By mounting the detachable cutter head 10 onto the first jaw arm 20 (or the second jaw arm 30) and ensuring that its curved cutting edge 201 is arranged parallel to the inherent first curved cutting edge 21 (or second curved cutting edge 31) on the first jaw (or the second jaw), the cutting plane of the detachable cutter head 10 is made consistent with the cutting plane of the inherent first curved cutting edge 21 (or second curved cutting edge 31) of the first jaw (or the second jaw). This ensures that the wire stripper's force distribution and cutting motion vary under different working modes (using the inherent cutting edge, using the inherent cutting edge and the cutter head, or using only the cutter head). The operating principle is consistent with the operating habits, laying the foundation for selective function switching; when using the inherent cutting edge for traditional wire stripping, the detachable blade head 10 can be slid to a position that does not affect the operation of the inherent cutting edge (positioned through the third positioning hole 42) or directly removed; when the inherent cutting edge cannot meet the wire stripping size requirements, the detachable blade head 10 can be installed to expand the wire stripping size requirements; when the synchronous wire stripping function is required, the detachable blade head 10 can be slid to the working position or mounted on the wire stripper; multiple functions are integrated into one and do not interfere with each other.The assembly relationship constitutes a hierarchical cooperation system. The first slot unit 40 cooperates with the slide rod positioning component 401 through its slot rail 41, undertaking the main sliding guidance function and the transmission of cutting force. The third positioning hole 42 provided on the first slot unit 40 corresponds one-to-one with the inherent cutting edge and can cooperate with the second elastic positioning component 402 at the end of the slide rod positioning component 401 to provide precise gear locking for the detachable cutter head 10 in multiple preset positions. The snap-fit ​​cooperation between the second slot unit 50 and the sliding buckle 102 provides a second constraint point, which together with the first slot unit 40 forms a three-dimensional guide rail structure to prevent the cutter head from tipping over and realizes the quick installation of the cutter head. This "primary and secondary coordination, point and surface combination" assembly method ensures that the cutter head module is smooth and wobbly during sliding adjustment and accurate and reliable during working positioning. The correspondence between the third positioning hole 42 and the inherent cutting edge allows the operator to intuitively and quickly position the cutter head according to the specifications of the inherent cutting edge, improving the intuitiveness and efficiency of operation. This assembly design allows the detachable cutter head 10 to be symmetrically mounted on the first clamp arm 20 or the second clamp arm 30. The first slot unit 40 and the second slot unit 50 on both sides are symmetrical and consistent in structure. This symmetrical design enhances the rationality of the tool design and the versatility of the parts, reduces the complexity of production and assembly, and makes it possible to flexibly configure the detachable cutter head 10 on the first clamp arm 20 and the second clamp arm 30 as needed in actual use (for example, one is mounted on each of the first clamp arm 20 and the second clamp arm 30 to achieve synchronous stripping, or it is mounted only on one side for special operations). This enhances the functional flexibility and adaptability of the wire stripper. The detachable cutter head 10 and the first clamp arm 20 or the second clamp arm 30 are connected by a specific assembly relationship between the first groove unit 40 and the second groove unit 50. This achieves precise three-dimensional guidance, multi-position accurate positioning, and functional synergy with the inherent cutting edge. The detachable cutter head 10 is seamlessly integrated with the mature traditional clamp structure, forming an integrated platform that can switch functions independently and work collaboratively. This not only ensures the high precision and stability of the synchronous wire stripping function, but also makes the wire stripper have the convenience of the traditional wire stripping mode. Ultimately, it has created a universal, efficient and reliable innovative wire stripping tool.

[0034] In practice, the present invention provides an adjustable inner and outer sheath synchronous stripping pliers, which achieves synchronous stripping of inner and outer sheaths through an adjustable cutter head structure and supports multi-diameter wire adaptation.

[0035] like Figure 2 As shown, the adjustable inner and outer sheath synchronous wire stripper includes a first clamp arm 20, a detachable cutter head 10, a second clamp arm 30, and a clamp arm pivot 60. It features an innovative design specifically for certain coaxial cables that require a section of the inner sheath to be retained when stripping the outer sheath.

[0036] The installation procedure for the detachable cutter head 10 is as follows: Figure 1 .like Figure 1As shown, the second spring 4022 is installed on the cylindrical tube 4011 formed by the vertical extension of the cutter head seat 100, the second round-headed pin 4023 is pressed into the cylindrical tube 4011, the first spring 302 is installed into the cutter head seat 100, the first round-headed pin 303 is pressed into the cutter head seat 100, the blade 200 is installed into the cutter head seat 100, and the blade 200 is rotatably fixed to the cutter head seat 100 by the rotating pin 203 through the central hole 202 of the blade 200.

[0037] The installation procedure for the detachable cutter head 10 and the first clamp arm 20 (or the second clamp arm 30) is as follows: Figure 3 .

[0038] like Figure 3 As shown, the second round-headed pin 4023 in the (200) detachable cutter head 10 is aligned with the groove rail 41 of the first groove unit 40, and the cutter head seat 100 is pressed into the second groove unit 50.

[0039] Inner liner blade adjustment method: Pinch the handle 205 on the blade 200 and rotate the blade 200 in the preset direction. The first round-headed pin 303 disengages from the first positioning hole 204 corresponding to the current arc-shaped cutting edge 201 on the blade 200. Further, the first spring 302 is compressed until the first round-headed pin 303 is completely pressed into the blade holder 100. Further still, continue to pinch the handle 205 on the blade 200 and rotate the blade 200 in the preset direction. The first round-headed pin 303 enters the first positioning hole 204 corresponding to the next arc-shaped cutting edge 201. The first round-headed pin 303 is springed back to its original position by the elastic force of the first spring 302, and the inner liner blade adjustment is completed.

[0040] Cutter head position adjustment method: Along a preset direction, push the detachable cutter head 10 to slide within the first slot unit 40, causing the second round-headed ejector pin 4023 to disengage from the second mounting hole 4021. Further, the second spring 4022 is compressed until the second round-headed ejector pin 4023 is completely pressed into the cylindrical tube 4011 of the cutter head seat 100. Further still, continue pushing the detachable cutter head 10 to slide within the first slot unit 40 in the preset direction, causing the second round-headed ejector pin 4023 to enter the next second mounting hole 4021. The second round-headed ejector pin 4023 is then springbacked back to its original position by the elastic force of the second spring 4022, completing the position adjustment of the detachable cutter head 10.

[0041] The wire stripping process of this invention is shown below. Figure 4First, adjust the blade 200 and the detachable cutter head 10 to their corresponding positions. Place the coaxial cable 70 between the first clamp arm 20 and the second clamp arm 30 on the first arc-shaped cutting edge 21 and the second arc-shaped cutting edge 31, which correspond to the diameter of the outer sheath 71 of the coaxial cable. Pinch the first clamp arm 20 and the second clamp arm 30 tightly. Next, pull out the coaxial cable 70 in the direction indicated by the arrow. At this time, the outer sheath 71 and the inner sheath 72 of the coaxial cable are simultaneously peeled off, exposing the coaxial cable core 73.

[0042] The beneficial effects of the adjustable inner and outer sheath simultaneous wire stripping pliers of this invention are as follows: 1. Synchronous stripping mechanism: Completes the stripping of inner and outer skin in a single operation, improving efficiency.

[0043] 2. Adjustable cutter head structure: The diameter and position of the cutting edge can be quickly adjusted through the cooperation of the ejector pin and the slide rail.

[0044] 3. Multi-blade adaptation design: The blade has multiple diameter blades to support different wires.

[0045] 4. High efficiency: Simultaneous peeling of inner and outer sheaths reduces operation steps (compared to existing technologies that require two peeling steps).

[0046] 5. Improved accuracy: The mechanical positioning structure eliminates errors from manual observation and reduces the risk of damage to the wire core.
