Description

Technical Field

[0001] This utility model relates to the technical field of cable stripping tools, specifically a cable insulation stripping tool. Background Technology

[0002] A cable insulation stripping tool is a specialized instrument for precisely removing the outer insulation material of cables. It typically features an adjustable blade structure to accommodate cables of different specifications and is controlled by a handle for stable grip. It can efficiently strip various insulation layers such as rubber and plastic without damaging the internal conductor. It is widely used in power installation, electrical maintenance, and other scenarios, providing convenient pre-processing for cable connection or testing operations.

[0003] For example, the Chinese authorized patent CN204290178U, entitled "A Cable Insulation Stripping Tool", includes a handle, a blade, a rolling pulley, and a connecting rod assembly. The blade is fixed to the front end of the handle by the handle. The connecting rod assembly includes upper and lower connecting rods, which are fixedly connected by a first support rod and a second support rod on the same plane. The vertical distance between the upper and lower connecting rods is adjustable. The rolling pulley is located at the connection between the connecting rod and the support rod. The handle is fixed in the middle of the upper connecting rod, so that the tip of the blade is parallel to the rotation direction of the rolling pulley.

[0004] While the existing technologies can remove the cable insulation layer, they are not very flexible. On the one hand, different cables have different diameters, making it difficult for the stripping tool to hold the cable securely. On the other hand, the insulation layer thickness of the cables also varies, which can easily damage the inner core or result in incomplete stripping of the insulation layer during the stripping process. Therefore, they do not meet the current requirements. In response, we propose a cable insulation layer stripping tool. Utility Model Content

[0005] The purpose of this invention is to provide a cable insulation stripping tool to solve the problems mentioned in the background art, such as the difficulty in achieving stable clamping of the cable and the difficulty in adjusting according to the insulation thickness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable insulation stripping tool, comprising a stripping tool body, a cutting depth adjustment rod provided on the front side of the upper end face of the stripping tool body, a blade mounting seat installed on the top of the cutting depth adjustment rod, a cutting blade fixedly installed on the upper end face of the blade mounting seat, a cable insulation cutting depth adjustment mechanism provided below the cutting depth adjustment rod for adjusting the extension distance of the cutting blade, a cable fastener block installed on the rear side of the upper end face of the stripping tool body, and a clamping force adjustment mechanism provided below the cable fastener block for clamping and fixing the cutting position of the cable.

[0007] Preferably, the cable insulation layer cutting depth adjustment mechanism includes a first movable cavity, and a cutting depth adjustment rod is slidably connected to the first movable cavity. A first screw is rotatably installed at the bottom of the first movable cavity. The cutting depth adjustment rod has a first threaded hole inside. The first screw extends into the inside of the first threaded hole, and the external thread of the first screw is frictionally engaged with the first threaded hole. A first adjusting wheel is rotatably installed at the front end of the stripping tool body, and the upper end of the first adjusting wheel is fixed to the first screw.

[0008] Preferably, the surface of the cutting blade is provided with graduation marks.

[0009] Preferably, the inner side of the cable buckle block has multiple ball bearing limiting grooves arranged in a rectangular array, and each ball bearing limiting groove is provided with a ball bearing inside.

[0010] Preferably, the clamping force adjustment mechanism includes a second movable cavity, and the cable buckle block is slidably connected to the second movable cavity. A second screw is rotatably installed at the bottom of the second movable cavity. A second threaded hole is provided in the lower end plate of the cable buckle block. The second screw extends into the interior of the second threaded hole, and the external thread of the second screw is frictionally engaged with the second threaded hole. A second adjusting wheel is rotatably installed at the rear end of the peeling tool body, and the upper end of the second adjusting wheel is fixed to the second screw.

[0011] Preferably, the second movable cavity is provided with limiting protrusions on both sides, and the cable buckle is provided with limiting grooves on both sides that slide and limit the limiting protrusions.

[0012] Preferably, the surface of the cutter head mounting base is threaded and is threaded to the top of the cutting depth adjustment rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a cutting depth adjustment rod to adjust the cutting depth according to the thickness of the cable insulation layer. During adjustment, the user only needs to rotate the first adjustment wheel, which drives the first screw to rotate. Under the friction between its external thread and the first threaded hole in the cutting depth adjustment rod, the rotational motion is converted into linear motion. Combined with the guiding effect of the first movable cavity and the cutting depth adjustment rod, the upper cutting blade is driven to extend and retract. Through the scale marks on the surface of the cutting blade, it is possible to know what thickness of insulation layer the cutting blade can cut at this time, ensuring the integrity of the insulation layer cut without damaging the inner core.

[0015] 2. This utility model features an adjustable cable clamp. After the cable is placed into the clamp, the user rotates the second adjusting wheel. Similarly, the friction between the second threaded hole and the second screw in the lower plate of the cable clamp causes the clamp to move towards the cable surface until the cable is clamped. This allows the cutting blade to extend into the cable's interior. At this point, the user simply rotates the stripping tool body, causing the cutting blade to rotate around the cable surface at one end, thus segmenting the cable insulation layer. Finally, the user pulls the stripping tool body to cut the segmented cable insulation layer for stripping. This not only simplifies the stripping process and improves work efficiency but also effectively avoids cutting deviations caused by unstable cable fixing, ensuring the accuracy and integrity of the insulation stripping work. It is suitable for stripping operations on cables of different diameters.

[0016] 3. This utility model incorporates multiple rectangularly arrayed ball bearings on the inner wall of the cable clip. When the user pulls the stripping tool, the ball bearings significantly reduce the friction between the cable clip and the cable surface, preventing cable sheath wear or tool jamming due to excessive friction, thus making the stripping operation easier and less strenuous. Simultaneously, the evenly distributed ball bearings ensure balanced force on the cable during stripping, further improving the stability and quality of insulation layer stripping and effectively reducing rework caused by operational errors.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 An embodiment of this utility model provides a cable insulation stripping tool, comprising a stripping tool body 1, a cutting depth adjustment rod 2 provided on the front side of the upper end face of the stripping tool body 1, a blade mounting seat 3 installed on the top of the cutting depth adjustment rod 2, a cutting blade 4 fixedly installed on the upper end face of the blade mounting seat 3, a cable insulation cutting depth adjustment mechanism provided below the cutting depth adjustment rod 2 for adjusting the extension distance of the cutting blade 4, a cable fastener 6 installed on the rear side of the upper end face of the stripping tool body 1, and a clamping force adjustment mechanism provided below the cable fastener 6 for clamping and fixing the cutting position of the cable;

[0025] The cutting depth adjustment mechanism controls the extension distance of the cutting blade 4 through mechanical transmission, while the clamping force adjustment mechanism clamps and fixes the cable through a mechanical structure. The two work together to provide a basic preparation for stripping the cable insulation layer, so that the cutting depth adjustment and cable clamping and fixing operations are independent yet closely coordinated. This allows users to flexibly adjust the cutting depth and clamping force according to different cable specifications, improving the applicability and versatility of the tool.

[0026] Please see Figure 2 The cable insulation layer cutting depth adjustment mechanism includes a first movable cavity 9, and a cutting depth adjustment rod 2 is slidably connected to the first movable cavity 9. A first screw 10 is rotatably installed at the bottom of the first movable cavity 9. A first threaded hole 11 is provided inside the cutting depth adjustment rod 2. The first screw 10 extends into the inside of the first threaded hole 11, and the external thread of the first screw 10 is frictionally engaged with the first threaded hole 11. A first adjusting wheel 5 is rotatably installed at the front end of the stripping tool body 1, and the upper end of the first adjusting wheel 5 is fixed to the first screw 10.

[0027] The user rotates the first adjusting wheel 5, causing the first screw 10 fixed to it to rotate. The external thread of the first screw 10 and the first threaded hole 11 inside the cutting depth adjusting rod 2 engage through friction, converting the rotational motion into linear motion. Since the cutting depth adjusting rod 2 is slidably connected to the first movable cavity 9, under the guidance of the first movable cavity 9, the cutting depth adjusting rod 2 moves up and down in a linear direction, thereby driving the top cutter head mounting seat 3 and the cutting blade 4 to extend and retract. This allows for precise adjustment of the extension distance of the cutting blade 4, meeting the cutting requirements of cable insulation layers of different thicknesses, and ensuring that the insulation layer is completely cut without damaging the internal wire core of the cable during stripping.

[0028] Please see Figure 1 and Figure 3 The surface of the cutting blade 4 is marked with a scale 17. The scale 17 is directly marked on the surface of the cutting blade 4. When the cutting blade 4 is extended and retracted under the action of the cutting depth adjustment mechanism, the user can intuitively understand the extension length of the cutting blade 4 by observing the value of the scale 17, thereby judging the thickness of the insulation layer that it can cut.

[0029] Please see Figure 2 The inner side of the cable clamp 6 has multiple ball bearing limiting grooves 7 arranged in a rectangular array. Each ball bearing limiting groove 7 contains a ball bearing 8. When the cable clamp 6 moves towards the cable surface and clamps the cable under the action of the clamping force adjustment mechanism, during the pulling process of the stripping tool body 1, the cable contacts the ball bearing 8 on the inner wall of the cable clamp 6. The ball bearing 8 rolls within the ball bearing limiting grooves 7, converting the sliding friction between the cable and the cable clamp 6 into rolling friction. The design of the ball bearing 8 effectively reduces the friction between the cable and the cable clamp 6, making the stripping tool smoother and less strenuous during pulling, reducing tool operating resistance, and preventing damage to the cable sheath due to excessive friction, thus ensuring the integrity of the cable.

[0030] Please see Figure 4 The clamping force adjustment mechanism includes a second movable cavity 12, and the cable buckle 6 is slidably connected to the second movable cavity 12. A second screw 13 is rotatably installed at the bottom of the second movable cavity 12. A second threaded hole 14 is provided in the lower end plate of the cable buckle 6. The second screw 13 extends into the interior of the second threaded hole 14, and the external thread of the second screw 13 is frictionally engaged with the second threaded hole 14. A second adjusting wheel 18 is rotatably installed at the rear end of the peeling tool body 1, and the upper end of the second adjusting wheel 18 is fixed to the second screw 13.

[0031] The user rotates the second adjusting wheel 18, causing the second screw 13 to rotate. The external thread of the second screw 13 engages with the second threaded hole 14 in the lower end plate of the cable clamp 6, converting the rotational motion into linear motion. Since the cable clamp 6 is slidably connected to the second movable cavity 12, guided by the second movable cavity 12, the cable clamp 6 moves up and down in a straight line, clamping or releasing the cable. This clamping force adjustment mechanism can flexibly adjust the clamping force according to the thickness and material of the cable, ensuring the cable remains stable and fixed during cutting, avoiding cutting deviations or damage caused by cable swaying.

[0032] Please see Figure 5 The second movable cavity 12 is provided with limiting protrusions 15 on both sides, and the cable buckle block 6 is provided with limiting grooves 16 on both sides that slide and limit the limiting protrusions 15. This further enhances the stability and accuracy of the cable buckle block 6 during movement, ensuring that the cable buckle block 6 can move smoothly along the predetermined direction, thereby achieving precise clamping of the cable and improving the reliability of clamping force adjustment.

[0033] Please see Figure 3 The surface of the cutter head mounting base 3 is threaded and is threaded to the top of the cutting depth adjustment rod 2. The thread on the surface of the cutter head mounting base 3 and the internal thread of the cutting depth adjustment rod 2 cooperate with each other. The user can rotate the cutter head mounting base 3 to fasten it to the cutting depth adjustment rod 2, so as to realize the detachable installation of the cutting blade 4. When it is necessary to replace the cutting blade 4 of different specifications, the cutter head mounting base 3 can be removed by rotating it in the opposite direction.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
