Description

Technical Field

[0001] This invention belongs to the field of power construction tools technology, specifically relating to a secondary cable integrated stripping pliers. Background Technology

[0002] In the field of power construction, especially during the construction and maintenance of secondary wiring, stripping the insulation layer of cables is a fundamental and frequent operation. Currently, the stripping of secondary cables mainly relies on a combination of various hand tools such as electrician's knives, utility knives, and diagonal pliers, as well as some general-purpose manual or electric wire stripping tools; however, these existing stripping methods have significant drawbacks in practical applications. Specifically, when dealing with secondary cables, which are composite structures with a thick outer insulation layer and an inner metal armor layer, existing tools generally lack effective depth control mechanisms. Whether using a knife or ordinary wire strippers, the cutting depth depends entirely on the operator's personal feel and experience. This uncontrollability leads to either cutting too deep and damaging the internal wires, rendering the cable unusable, or cutting too shallowly and failing to effectively strip the insulation layer, resulting in inconsistent stripping quality and seriously affecting the reliability and safety of secondary wiring.

[0003] It is evident that existing technologies often suffer from the problem of unstable peeling quality due to uncontrollable depth control; this is the core shortcoming of existing technologies.

[0004] In view of this, it is very necessary to provide a secondary cable integrated stripping pliers to solve the above-mentioned defects in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the existing technology, which suffers from unstable stripping quality due to uncontrollable depth control, by providing a secondary cable integrated stripping pliers to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a secondary cable integrated stripping pliers, comprising a pliers body; the pliers body is composed of a first pliers arm and a second pliers arm that are hinged to each other by a hinge shaft; The first clamp arm has a first clamping part at its front end, and the second clamp arm has a second clamping part at its front end; A return spring is provided at the hinge shaft. After the operator releases the clamp arms, the first and second clamp arms are automatically driven to return to the open position, which facilitates the next operation. A longitudinal cutting component is fixedly installed on the first clamping part, and a circumferential cutting component is fixedly installed on the second clamping part; a wire guide corresponding to the position of the longitudinal cutting component is provided on the second clamping part; a wire guide corresponding to the position of the circumferential cutting component is provided on the first clamping part. The clamp-like body also includes a depth adjustment component and an armor shearing component; The longitudinal cutting assembly includes a longitudinal blade made of alloy steel and a blade mounting base. The longitudinal blade is heat-treated and ground to ensure sufficient sharpness and durability. The longitudinal blade is fixedly mounted on the inner side of the first clamping part by the blade mounting base. The cutting direction of the longitudinal blade forms an acute angle with the axis of the cable to be stripped, preferably 30°, so that the contact between the blade edge and the cable insulation is a "point contact". This allows for efficient cutting with minimal gripping force from the operator by utilizing the principle of pressure. This design not only saves more effort but also effectively guides the cutting direction, significantly reducing the risk of blade slippage, injury to the operator, or damage to the internal core of the cable in traditional operations. The circumferential cutting assembly consists of a circumferential blade and a blade mounting base made of alloy steel. The circumferential blade undergoes heat treatment and grinding to ensure performance. The circumferential blade is fixedly mounted on the inner side of the second clamping part via the blade mounting base. The cutting direction of the circumferential blade is set perpendicular to the cable axis. During operation, after the operator grips the clamp arm to allow the circumferential blade to cut into the insulation layer, the operator can rotate the entire clamp body to complete a complete and regular cut around the circumference of the cable using the vertically set blade.

[0007] The depth adjustment assembly includes a limiting screw, which is mounted on the first clamp arm with its end facing the rear end face of the blade mounting seat; the limiting screw preferably adopts a fine thread design to obtain a smaller pitch, ensuring higher axial adjustment accuracy and good self-locking performance; Both the longitudinal and circumferential cutting components employ a concealed blade design. The longitudinal and circumferential blades switch between operating and non-operating states through the opening and closing action of the first and second clamping arms. In the non-operating state, the longitudinal and circumferential blades retract into the blade mounting seat of the first clamping part, with the effective cutting edge not exposed. In the operating state, gripping the first and second clamping arms causes them to rotate relative to each other. The driving inclined surface or linkage mechanism on the inner side of the first clamping arm pushes the blade mounting seat forward against the tension of the return spring, causing the blade to extend out of the mounting seat and expose the effective cutting segment, cutting into the cable insulation layer. After releasing the clamping arms, the return spring located at the hinge shaft drives the first and second clamping arms to return to the open position. The return spring pulls the blade mounting seat backward, causing the blade to retract into the mounting seat. The rear end face of the blade mounting seat is opposite the end of the limiting screw. By rotating the limiting screw, its axial position extending into the first clamping arm is adjusted, limiting the maximum displacement of the blade mounting seat, thereby physically limiting the depth of the blade cutting into the cable insulation layer to a safe preset value. Operators can pre-rotate the limit screw to the appropriate position according to the insulation thickness of different cable specifications. This design enables the stripping depth to be standardized and quantifiable, completely eliminating the reliance on the operator's personal experience and feel, and ensuring the consistency of quality and the safety of the wire core in every cutting operation.

[0008] The second clamping part is equipped with a wire cutter corresponding to the position of the longitudinal cutting component, which is a longitudinal wire cutter. The longitudinal wire cutter includes a right-angled base for the longitudinal wire cutter. A freely rotatable cylindrical guide wheel assembly is embedded in a plane of the right-angled base for the longitudinal wire cutter, which is parallel to the opening and closing surface of the clamp arm. The axial direction of the guide wheel is perpendicular to the cable's infeed direction. During operation, the cable moves against the guide wheel, providing stable radial support for the cable and precisely guiding the cable to move in a straight line along its axial direction, thereby ensuring the straightness of the longitudinal cutting trajectory. The first clamping part is equipped with a wire cutter corresponding to the position of the circumferential cutting component, which is also the position of the circumferential cutting component on the second clamping part. The circumferential cutting wire cutter includes a circumferential cutting wire cutter bent right-angle body base, and another cylindrical guide wheel assembly is embedded in a plane of the circumferential cutting wire cutter bent right-angle body base that is perpendicular to the opening and closing surface of the clamp arm. The axial direction of the guide wheel is parallel to the cable's inlet direction. During operation, the cable is close to the guide wheel, which provides stable tangential support for the cable during rotary cutting and guides the clamp body to rotate around the cable, thereby ensuring the regularity of the circumferential cutting trajectory and forming a complete circular cut. The guide wheels of the longitudinal and circumferential wire cutters are mounted perpendicular to each other, and their rotation axes are perpendicular to each other. The longitudinal wire cutter guides linear displacement, while the circumferential wire cutter guides rotational motion. Together, the longitudinal and circumferential wire cutters form a complete two-dimensional guiding system, which constrains and guides the movement direction of the cable in different cutting processes, solving the quality and safety problems of easy deviation in cutting direction and uneven cuts in manual operation.

[0009] The armor stripping assembly features a metal shear head at the head of the clamp body. The metal shear head can be fixedly connected to the clamp body or integrally formed with the clamp arm. The metal shear head is preferably made of manganese steel to ensure sufficient hardness and shearing strength, and its blade surface is typically electroplated for sharpness, rust resistance, and non-magnetic properties. After the operator completes the cutting and stripping of the cable insulation layer using the longitudinal and circumferential cutting components, there is no need to change other tools; the same stripping pliers can be used directly with the metal shear head to cut and remove exposed steel and aluminum cable armor layers. This integrates the traditionally separate processes of "stripping" and "armor cutting" and the two sets of tools into a single, continuous operation, simplifying the workflow, improving efficiency, and reducing the number of tools required.

[0010] The clamping surfaces of the first clamping part and the second clamping part are provided with anti-slip textures or covered with rubber anti-slip pads; this can significantly enhance the friction between the clamping part and the cable surface, thereby ensuring that the cable is firmly fixed during the cutting process, effectively preventing the cable from sliding or shifting due to force, and further improving the stability and accuracy of the cutting operation.

[0011] The operation of the integrated secondary cable stripping pliers includes the following steps: Based on the insulation thickness of the secondary cable to be stripped, the operator pre-adjusts the extension of the longitudinal and circumferential blades by rotating the limiting screws at the blade mounting seats of the longitudinal and circumferential cutting components, thereby setting a safe cutting depth. Place the cable between the first clamping part and the second clamping part, and make the cable close to the guide wheel of the longitudinal wire cutter. Grip the first clamp arm and the second clamp arm tightly, so that the longitudinal blade cuts into the outer insulation of the cable. Keep gripping, and pull the entire stripping pliers smoothly along the cable axis. Under the guidance of the guide wheel of the wire cutter, complete the longitudinal straight cut of the insulation. Adjust the cable position so that the cable is close to the guide wheel of the circumferential cable cutter; tighten the clamp arm again so that the circumferential blade cuts into the insulation; hold the clamp body and rotate it around the cable once to complete the circumferential cut of the insulation using the circumferential blade; Manually peel off and remove the cable insulation that has been separated by longitudinal and circumferential cuts; The exposed cable armor layer is cut and removed directly using the sheet metal shear head located at the head of the clamp body; Release the clamp arms, and the return spring will automatically reset the first and second clamp arms to the open state, ready for the next operation; Through the above steps, a single person can independently, safely, and continuously complete the entire standardized stripping operation of secondary cables, from cutting the insulation layer to removing the armor layer.

[0012] The beneficial effects of this invention are as follows: by highly integrating longitudinal cutting, circumferential cutting, and armor removal functions into a single clamp body, and equipping it with a depth adjustment component and a two-dimensional guiding system, the stripping operation is standardized and integrated; the blade extension and retraction are driven by the opening and closing action of the clamp arms, and the cutting depth is precisely controlled by physical limits, eliminating the reliance on feel and experience in traditional operations and effectively avoiding the risk of wire core damage due to uncontrolled depth; the concealed blade design and the specific angle cutting method improve operational safety, while the guiding mechanism ensures the straightness and regularity of the cutting trajectory, thereby improving the construction quality and work efficiency of secondary wiring.

[0013] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0014] Therefore, it is evident that the present invention has substantial features and progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following implementation methods.

[0021] Example 1: This invention provides a secondary cable integrated stripping pliers, including a pliers body, such as... Figure 1 As shown, the clamp body is composed of a first clamp arm 1 and a second clamp arm 2 hinged together by a hinge shaft 9, forming a lever-like structure with opening and closing function; the first clamp arm 1 and the second clamp arm 2 are usually long strip-shaped metal parts, with the tail end forming an operating handle that is easy to hold, and the front end being the function execution area; A return spring is installed at the hinge shaft 9. When the operator grips the handles of the two clamp arms and brings them closer together, the front end of the clamp body closes, performing clamping, cutting and other actions. When the operator releases the handles, under the elastic force of the return spring, the first clamp arm 1 and the second clamp arm 2 automatically rotate in the opposite direction around the hinge shaft 9, returning to the open state, and preparing for the next operation. The entire clamp body has a compact and robust structure, providing a stable mechanical foundation and spatial layout framework for integrating cutting components at its front end, shearing components at its rear end, and achieving precise guidance and depth adjustment functions.

[0022] A first clamping part 3 is integrated at the front end of the first clamping arm 1; a second clamping part 4 is integrated at the front end of the second clamping arm 2; the first clamping part 3 and the second clamping part 4 are opposite to each other, and when the clamping arms are closed, they form a V-shaped or arc-shaped space for stably clamping and fixing the cable to be stripped, which is the basis for all subsequent precise operations. A longitudinal cutting component 5 is fixedly installed on the first clamping part 3, and a circumferential cutting component 6 is fixedly installed on the second clamping part 4; a wire guide corresponding to the longitudinal cutting component 5 is provided on the second clamping part 4; a wire guide corresponding to the circumferential cutting component 6 is provided on the first clamping part 3. The clamp-like body also includes a depth adjustment component and an armor shearing component; The longitudinal cutting assembly 5 includes a longitudinal blade and a blade mounting base made of alloy steel. The longitudinal blade is heat-treated and ground to ensure sufficient sharpness and durability. The longitudinal blade is fixedly mounted on the inner side of the first clamping part 3 via the blade mounting base. The cutting direction of the longitudinal blade forms an acute angle with the axial direction of the cable to be stripped, preferably 30°, so that the contact between the blade edge and the cable insulation sheath is a "point contact". This design can achieve efficient cutting with less gripping force by the operator by utilizing the pressure principle. This design is not only more labor-saving, but also effectively guides the cutting direction, significantly reducing the risk of blade slippage, injury to the operator, or damage to the internal core of the cable in traditional operations. The circumferential cutting assembly 6 consists of a circumferential blade and a blade mounting base made of alloy steel. The circumferential blade undergoes heat treatment and grinding to ensure performance. The circumferential blade is fixedly mounted on the second clamping part 4 via the blade mounting base. The cutting direction of the circumferential blade is set perpendicular to the cable axis. During operation, after the operator grips the clamp arm to make the circumferential blade cut into the insulation layer, the operator can rotate the entire clamp body to complete a complete and regular cut around the circumference of the cable using the vertically set blade.

[0023] The second clamping part 4 is provided with a wire cutter 7 corresponding to the longitudinal cutting assembly 5, such as... Figure 2 As shown, the longitudinal wire cutter 7 includes a right-angled body base 12 for the longitudinal wire cutter. A first cylindrical guide wheel assembly 11 is rotatably mounted on a plane of the longitudinal wire cutter right-angled body base 12 that is parallel to the opening and closing plane of the clamp arm. The rotation axis of the first cylindrical guide wheel assembly 11 is set to be perpendicular to the axial feed direction of the cable to be stripped. In the working state, the outer surface of the cable to be stripped moves against the first cylindrical guide wheel assembly 11. The first cylindrical guide wheel assembly 11 provides stable radial support perpendicular to the cable's axial direction and accurately guides the cable to make linear displacement along its own axial direction, thereby ensuring the straightness of the longitudinal cutting trajectory. The first clamping part 3 is provided with a wire guide corresponding to the circumferential cutting assembly 6, which is a circumferential cutting wire guide 8; for example Figure 3 As shown, the circumferential wire cutter 8 includes a circumferential wire cutter bent right-angle body base 14. On a plane perpendicular to the opening and closing plane of the clamp arm, another cylindrical guide wheel assembly, namely the second cylindrical guide wheel assembly 13, is rotatably embedded. The rotation axis of the second cylindrical guide wheel assembly 13 is set to be parallel to the axial feed direction of the cable to be stripped. In the working state, the outer surface of the cable to be stripped is against the second cylindrical guide wheel assembly 13. The second cylindrical guide wheel assembly 13 provides stable tangential support for the cable when it rotates and cuts around its circumference, and guides the clamp body to rotate around the cable, thereby ensuring the regularity of the circumferential cutting trajectory and forming a complete annular cut. The guide wheel mounting plane of the longitudinal wire cutter 7 is perpendicular to the guide wheel mounting plane of the circumferential wire cutter 8; correspondingly, the rotation axis of the first cylindrical guide wheel group 11 is also perpendicular to the rotation axis of the second cylindrical guide wheel group 13; the subsystem composed of the longitudinal wire cutter 7 and the first cylindrical guide wheel group 11 is responsible for guiding the linear displacement of the cable along its axial direction; the subsystem composed of the circumferential wire cutter 8 and the second cylindrical guide wheel group 13 is responsible for guiding the circumferential rotation of the clamp body around the cable; the above two subsystems are integrated into the clamp body to form a guide system that constrains and guides the motion path in two-dimensional orthogonal directions respectively. Through the precise setting of spatial geometric relationships, independent and high-precision motion guidance is provided for the key axial cutting and circumferential cutting processes in cable stripping operations, thereby effectively solving the quality and safety hazards such as skewed cutting trajectory and uneven cut caused by inaccurate manual operation direction control.

[0024] The depth adjustment assembly includes a limiting screw 10. The tail of the first clamp arm is provided with a threaded hole, and the limiting screw 10 is screwed into the threaded hole. The blade mounting seats of the longitudinal cutting assembly 5 and the circumferential cutting assembly 6 are slidably disposed in the groove of the first clamp arm 1, and the rear end of the blade mounting seat is provided with a rearward protruding limiting boss. The end of the limiting screw 10 faces the limiting boss. By rotating the limiting screw 10, its axial position extending into the first clamp arm 1 is adjusted to abut against the limiting boss, thereby limiting the maximum displacement of the blade mounting seat.

[0025] When the limiting screw 10 is screwed in deeply, its end abuts against the limiting boss earlier, restricting the forward sliding stroke of the blade mounting seat, thereby making the cutting depth of the blade shallower; when the limiting screw is screwed out, the sliding stroke of the blade mounting seat increases, and the cutting depth increases; the limiting screw 10 preferably adopts a fine thread design to obtain a smaller pitch, ensuring higher axial adjustment accuracy and good self-locking performance. Both the longitudinal cutting component 5 and the circumferential cutting component 6 adopt a concealed blade design; the inner side of the first clamp arm 1 is provided with a driving inclined surface or a linkage mechanism, and a reset spring is connected between the blade mounting seat and the clamp arm; One end of the reset spring is connected to the rear end of the blade mounting seat, and the other end is connected to the fixing post of the first clamp arm 1. It is used to provide a restoring force when the clamp arm is released, so that the blade retracts.

[0026] In the working state, grip the first clamp arm 1 and the second clamp arm 2. The inclined mechanism on the inner side of the first clamp arm 1 pushes the blade mounting seat forward to overcome the tension of the return spring, so that the blade extends out of the blade mounting seat and exposes the effective cutting section, cutting into the cable insulation layer. After releasing the clamp arm, the return spring located at the hinge shaft drives the first clamp arm 1 and the second clamp arm 2 to return to the open position. At the same time, the return spring pulls the blade mounting seat to slide backward, and the blade retracts into the blade mounting seat. Operators can pre-rotate the limit screw 10 to the appropriate position according to the insulation thickness of different cable specifications; this design enables the stripping depth to be standardized and quantifiable, completely eliminating the reliance on the operator's personal experience and feel, and ensuring the consistency of quality and the safety of the wire core in every cutting operation.

[0027] The depth adjustment component enables quantifiable and reproducible standardized control of the key parameter of cutting depth in cable stripping operations. This eliminates the high dependence on the operator's personal feel, experience, and instantaneous judgment in traditional manual operations, and prevents quality defects caused by repeated operations due to excessive cutting damaging the wire core or insufficient cutting of the insulation layer. Through physical limiting, it ensures that the cutting depth remains highly consistent for every cut performed by the same operator or different operators, regardless of the operating conditions. This greatly improves the consistency of the final terminal preparation quality and the predictability of the operation process in batch operations, effectively protecting the cable core.

[0028] The armor cutting component is integrated into the head of the clamp body; the armor cutting component is a sheet metal shear head; the sheet metal shear head is either a fixed connection type or a one-piece molded type. The fixed connection type specifically refers to the sheet metal shear head being fixedly connected to the head of the first clamp arm 1 and / or the second clamp arm 2 by means such as welding, riveting, or threaded fastening; the integral molding type specifically refers to the sheet metal shear head and the head of the first clamp arm 1 and / or the second clamp arm 2 being manufactured into an integral component by processes such as forging and precision casting to achieve higher structural strength and reliability.

[0029] The shear head is preferably made of heat-treated and strengthened manganese steel to ensure that the blade has sufficient hardness, wear resistance and shearing strength to cut the armor materials commonly used in cables. Furthermore, the blade surface of the sheet metal shear head is preferably treated with electroplating; this not only helps to maintain and improve the sharpness of the blade, but also significantly improves its corrosion resistance and makes it meet the non-magnetic requirements for precision operating tools in power construction, avoiding interference with sensitive electrical equipment or adsorption of metal debris due to the tool being magnetic. The armor shearing component works in conjunction with the front-end cutting component to achieve a high degree of integration and continuity of the operation process; specifically, in the operation process: The operator uses the longitudinal cutting component 5 and the circumferential cutting component 6 located at the front end of the clamp to precisely cut and peel off the cable insulation layer. After the insulation layer is removed, the metal armor layer of the cable is exposed. The operator does not need to interrupt the operation, put down the tool, or change to other cutting tools. The operator can directly operate the same stripping pliers by simply adjusting the hand angle and using the sheet metal shear head integrated into the head to efficiently and cleanly cut and remove the exposed armor layer.

[0030] The armor stripping assembly integrates the two key processes of insulation stripping and armor shearing, which are usually performed separately by two sets of tools in traditional cable termination preparation, into a single, continuous operation sequence using a single tool. This simplifies the workflow, eliminates time delays and redundant actions caused by tool switching, improves overall work efficiency, and is suitable for power construction scenarios where space is limited, work at heights, or repetitive tasks are required. It also reduces the number of specialized tools that operators need to carry and maintain, improving the convenience of working outdoors and the ease of tool management.

[0031] On the clamping surfaces of the first clamping part 3 and the second clamping part 4, anti-slip structures for enhancing friction are provided; the anti-slip structures include surface textured anti-slip structures and covering material anti-slip structures. The surface textured anti-slip structure specifically involves directly machining anti-slip patterns onto the clamping surfaces of the first clamping part 3 and / or the second clamping part 4; the anti-slip patterns include continuous serrations, cross knurling, dotted protrusions, or other geometric patterns that can increase surface roughness; the covering material type anti-slip structure specifically involves covering or bonding a layer of anti-slip pad made of elastic material onto the clamping surfaces of the first clamping part 3 and / or the second clamping part 4; the elastic material is preferably rubber, silicone rubber, or a polymer material with similar high coefficient of friction and cushioning properties; When the first clamping part 3 and the second clamping part 4 clamp the cable, the anti-slip structure can significantly increase the static friction force and dynamic friction coefficient between the clamping surface and the outer sheath of the cable. Throughout the process of the operator gripping the clamp arm, the blade of the longitudinal cutting component 5 or the circumferential cutting component 6 cutting into the cable insulation layer and applying load, the anti-slip structure ensures that the cable is firmly and non-slippedly fixed within the V-shaped or arc-shaped space formed by the clamping part. By effectively preventing the cable from sliding axially or rotating around due to the cutting reaction force, a stable mechanical benchmark and reference coordinate system is established for the entire cutting operation. Based on a stable clamping mechanism, the anti-slip structure works synergistically with the longitudinal wire cutter 7, the circumferential wire cutter 8, and the depth adjustment component; ensuring that the motion path set by the guide system and the cutting depth set by the depth adjustment component can be accurately and without distortion transmitted and applied to the expected cutting position of the cable, thereby ultimately and comprehensively improving the straightness of the longitudinal cut, the roundness of the circumferential cut, and the repeatability and quality consistency of the entire stripping operation.

[0032] Example 2: This embodiment provides a method for using integrated secondary cable stripping pliers, including the following steps: Based on the nominal or measured thickness of the insulation layer of the secondary cable to be stripped, the operator adjusts the axial position of the blade extending into the first clamp arm by rotating the limit screw 10, thereby limiting the maximum displacement of the blade mounting seat and physically limiting the cutting depth of the two cutting modes within the pre-calculated safety value. This step realizes the quantifiable and standardized preset of the stripping depth, which is the primary link to ensure the safety of the operation and the integrity of the wire core. The cable is placed into the clamping space formed by the first clamping part 3 and the second clamping part 4, and the outer surface of the cable is ensured to be in contact with the first cylindrical guide wheel group 11 of the longitudinal wire cutter 7; the anti-slip structure on the clamping surface can provide initial fixation; Grip the first clamp arm 1 and the second clamp arm 2 tightly, and drive the longitudinal blade to cut into the cable insulation layer at a preset depth; while maintaining the gripping force, smoothly pull the entire stripping pliers along the cable axis; during this process, the first cylindrical guide wheel group 11 of the longitudinal wire cutter 7 continuously provides radial support and guidance for the cable, precisely constraining it to only move in a straight line along the axial direction, thereby completing a straight and continuous longitudinal cut. After completing the longitudinal cut, adjust the position of the cable within the clamping space so that it is against the second cylindrical guide wheel group 13 of the circumferential wire cutter 8; tighten the clamp arm again and drive the circumferential blade to cut into the insulation layer to a preset depth; the operator holds the clamp body and rotates it smoothly around the cable circumference for a full circle, using its tail as a general fulcrum; during this process, the second cylindrical guide wheel group 13 of the circumferential wire cutter 8 provides tangential support and rotational guidance for the cable, ensuring that the clamp body makes regular circular motion around the cable axis, and completes a complete and deep circumferential cut using the circumferential blade; the cable insulation, which has been completely separated by the longitudinal and circumferential cuts, is peeled off and removed from the wire core; After the insulation layer is removed and the cable's metal armor layer is exposed, the operator does not need to change tools; they can directly operate the same stripping pliers and use the armor cutting component integrated into its head to cut and remove the exposed steel strip, aluminum strip, and other armor layers. Release the grip on the first clamp arm 1 and the second clamp arm 2. Driven by the return spring located at the hinge shaft 9, the two clamp arms automatically return to the open state, and the tool returns to the initial configuration ready for operation, preparing for the next operation.

[0033] By performing the above steps in sequence, this stripping pliers allows a single person to independently complete a complete set of standardized and continuous stripping operations, from depth preset, precise cutting and peeling of the insulation layer to the final treatment of the armor layer. This method integrates the traditionally scattered procedures that rely on multiple tools and high manual dexterity into a safe, efficient, and precision-controllable continuous operation sequence, which is particularly suitable for power secondary wiring construction scenarios with stringent requirements for work quality and safety.
