Description

Technical Field

[0001] This invention relates to the field of peeler technology, and particularly to a quick-connect hand-cranked peeler. Background Technology

[0002] In fields such as power transmission, electrical assembly, building wiring, and the manufacturing of power electronic components such as insulated gate bipolar transistor chips and modules, the stripping of the insulation layer at the cable end is a key process to ensure reliable wiring and stable operation of devices. This process directly affects the quality of line continuity, assembly accuracy, and production efficiency.

[0003] Existing hand-cranked wire strippers mostly use fixed-specification clamping structures, which can only be adapted to cables with a limited range of wire diameters and fixed insulation thicknesses. When dealing with cables of different diameters and insulation thicknesses, it is necessary to frequently change special clamps or adjust complex mechanisms, which increases the preparation time and thus prolongs the operation time and affects the efficiency of operation. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a quick-connect hand-cranked peeler.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a quick-connect hand-cranked wire stripper, comprising a housing with an internally hollow structure, wherein a circular through hole communicating with the interior of the housing is provided through the side wall of the housing, and a notch communicating with the circular through hole is provided on the side wall of the housing, wherein a rotating frame is rotatably installed in the circular through hole of the housing, and a wire stripping mechanism is provided on the housing for clamping cables of various diameters and cutting insulation layers of various thicknesses.

[0006] By adopting the above technical solution, the cable to be stripped is first passed through the notch until it enters the rotating frame. Then, the stripping mechanism clamps the cable to be stripped, and finally, the cable is stripped. The stripping mechanism can locate and strip cables with various diameters and insulation thicknesses, which increases the functionality of the device and expands its application range. It also reduces the frequency of changing special clamps, shortens the operation time, and helps to improve operation efficiency.

[0007] Furthermore, the rotating frame includes two horizontal frames and an arc frame, and the wire stripping mechanism includes a clamping assembly. The clamping assembly includes a bidirectional screw rod that passes through the two horizontal frames of the rotating frame and is rotatably connected to the rotating frame, a vertical rod fixed between the two horizontal frames of the rotating frame, an upper clamping plate that is slidably disposed on the vertical rod and threadedly connected to the bidirectional screw rod, a lower clamping plate that is slidably disposed on the vertical rod and threadedly connected to the bidirectional screw rod, and a first lifting ring fixed to the lower end of the bidirectional screw rod. The bidirectional screw rod is provided with two sections of threads with opposite helices and equal pitch. The upper clamping plate and the lower clamping plate are respectively disposed on the two sections of threads and threadedly connected. The wire stripping mechanism also includes a wire stripping assembly for cutting the cable insulation layer.

[0008] By adopting the above technical solution, after the cable enters the rotating frame, rotating the first lifting ring drives the bidirectional screw to rotate. Since the upper and lower clamping plates are both slidably engaged with the vertical rod, and the bidirectional screw is provided with two sections of threads with opposite helices and equal pitch, the upper and lower clamping plates are respectively set on the two sections of threads and threadedly connected, so that the upper and lower clamping plates move closer or further away from each other, thereby realizing the clamping or loosening operation of the cable surface. By adjusting the distance between the upper and lower clamping plates, cables of various outer diameters can be operated.

[0009] Furthermore, the wire stripping assembly includes a blade holder fixed to the lower clamp plate and having an internally hollow structure. A sliding groove communicating with the inside of the blade holder is provided through the side wall of the blade holder. The wire stripping assembly also includes a blade adjusting screw that is provided through the bottom of the blade holder and cooperates with the blade holder, a second lifting ring fixed to the lower end of the blade adjusting screw, a sliding block that is rotatably installed on the upper end of the blade adjusting screw and slides in cooperation with the inside of the blade holder, a cutting blade fixed to the top of the sliding block and passing through the sliding groove, and a first spring fixed between the top of the cutting blade and the inner top wall of the blade holder. The cutting blade slides in cooperation with the sliding groove. The wire stripping assembly also includes a lifting assembly for driving the cutting blade to rise and fall. A rotating mechanism for driving the rotating frame to rotate is provided on the housing.

[0010] By adopting the above technical solution, during the upward movement of the lower clamping plate, the knife holder fixed to the lower clamping plate, the knife adjusting screw connected to the knife holder, the second lifting ring connected to the knife adjusting screw, the sliding block connected to the knife adjusting screw, and the cutting blade connected to the sliding block all rise. When the upper and lower clamping plates clamp the cable, the cutting part of the cutting blade is in contact with the surface of the cable. At this time, the lifting assembly is operated to drive the cutting blade to rise until the cutting part of the cutting blade cuts the insulation part in contact with the cable. Finally, the rotating mechanism is operated to drive the rotating frame to rotate, which drives the cutting blade to rotate and cut the cable insulation part all around, thereby realizing the cable stripping operation. By operating the lifting distance of the cutting blade, it is possible to cut and strip cables with insulation parts of various thicknesses, thus expanding the application range of the device.

[0011] Furthermore, the lifting assembly includes a first set screw that passes through the side wall of the tool holder and is threadedly connected to the tool holder. The side wall of the tool holder has a threaded through hole. The lifting assembly also includes a second set screw that is threadedly connected to the threaded through hole, a compression spring fixed to the second set screw near the end of the tool holder, and a steel ball fixed to the compression spring near the side wall of the tool holder. The side wall of the adjusting screw has a spiral groove for the first set screw to pass through and slide. The side wall of the adjusting screw has an auxiliary groove for the steel ball to pass through and engage. The side walls on both sides of the auxiliary groove are inclined surfaces. The distance between the two inclined surfaces of the auxiliary groove gradually decreases from the steel ball toward the axis of the adjusting screw. Multiple auxiliary grooves are provided and are evenly distributed about the axis of the adjusting screw.

[0012] By adopting the above technical solution, rotating the second lifting ring drives the adjusting screw to rotate. Due to the sliding engagement between the spiral groove and the first set screw, the adjusting screw can drive the second lifting ring, the sliding block, and the cutting blade to rise and fall. In addition, each auxiliary groove corresponds to a range of cable insulation depth. During the rotation of the adjusting screw, the steel ball will first change from contact with the corresponding auxiliary groove to contact with the surface of the adjusting screw. During this process, as the distance between the two inclined surfaces of the auxiliary groove gradually decreases from the steel ball towards the axis of the adjusting screw, the steel ball gradually moves away from the axis of the adjusting screw, the compression spring is stressed and gradually contracts, and finally the steel ball will change from contact with the surface of the adjusting screw to contact with another auxiliary groove. During this process, the compression spring gradually extends and returns to its original position, and drives the steel ball fixed with the compression spring to move towards the axis of the adjusting screw until the steel ball passes into the corresponding auxiliary groove. Since the steel ball is made of steel, there will be a certain sound when the steel ball contacts multiple auxiliary grooves, so that the operator can judge whether the steel ball is aligned with the auxiliary groove, so that the operator can adjust the height of the cutting blade.

[0013] Furthermore, the arc frame of the rotating frame is rotatably connected to the circular through hole, and the two cross frames of the rotating frame are fixed on the arc frame. The rotating mechanism includes a transmission assembly, which includes a driven shaft rotatably mounted in the housing, a driven gear fixedly sleeved on the driven shaft, a first arc gear fixedly sleeved on the arc frame of the rotating frame and meshing with the driven gear, a second arc gear rotatably mounted on one end of the first arc gear, a drive shaft rotatably mounted in the housing, and a drive gear fixedly sleeved on the drive shaft and meshing with the driven gear. A friction pad is provided at the connection between the drive shaft and the second arc gear, and an arc slot is provided at the other end of the second arc gear to be inserted into the other end of the first arc gear. The rotating mechanism also includes a drive assembly for driving the drive shaft to rotate.

[0014] By adopting the above technical solution, the cable is first inserted into the rotating frame, and then the second arc gear is flipped until the other end of the second arc gear is inserted into the other end of the first arc gear. At this time, the rotating mechanism is operated to drive the drive shaft to rotate, which can drive the drive gear fixed to the drive shaft, the driven gear meshing with the drive gear, the first arc gear meshing with the driven gear, and the rotating frame fixed to the first arc gear to rotate, thereby realizing the operation of cutting the cable insulation.

[0015] Furthermore, the drive assembly includes a first sleeve fixed to the bottom of the housing, a drive shaft that passes through the bottom of the housing and is rotatably connected to the housing, a first bevel gear fixedly sleeved on the drive shaft, and a second bevel gear fixedly sleeved on the drive shaft and meshing with the first bevel gear. The lower end of the drive shaft passes through the top of the first sleeve and is rotatably connected to the first sleeve. The first sleeve is provided with an auxiliary mechanism to facilitate the rotation of the drive shaft.

[0016] By adopting the above technical solution, the operating auxiliary mechanism drives the drive shaft to rotate, which in turn drives the first bevel gear fixed to the drive shaft, the second bevel gear meshing with the first bevel gear, and the drive shaft fixed to the second bevel gear to rotate, thereby realizing the operation of rotating the frame.

[0017] Furthermore, the auxiliary mechanism includes a connecting assembly, which includes a first sleeve disposed below the first sleeve, a first connecting rod rotatably installed inside the first sleeve and coaxially disposed with the first sleeve, a connecting sleeve fixedly sleeved on the upper end of the first sleeve and inserted into the first sleeve, a first bolt disposed on the first sleeve and abutting against the side wall of the connecting sleeve, and a second sleeve fixedly sleeved on the lower end of the first bolt. The upper end of the first connecting rod is inserted into and splined with the lower end of the drive shaft. The auxiliary mechanism also includes an extension assembly for increasing the length of the first sleeve.

[0018] By adopting the above technical solution, rotating the first connecting rod will cause the drive shaft to rotate because the upper end of the first connecting rod is inserted into and splined with the lower end of the drive shaft. In addition, the addition of the extended component can increase the overall length of the first sleeve, thereby expanding the applicability of the device.

[0019] Furthermore, the extension assembly includes a second sleeve disposed below the first sleeve, a third sleeve fixedly sleeved on the upper end of the second sleeve and inserted into the inner wall of the second sleeve, a second bolt disposed on the second sleeve and abutting against the side wall of the third sleeve, a second connecting rod rotatably installed inside the second sleeve and coaxially disposed with the second sleeve, and a third sleeve fixedly sleeved on the lower end of the second sleeve. The upper end of the second connecting rod is inserted into and splined with the lower end of the first connecting rod. The auxiliary mechanism also includes a rotating assembly for driving the second connecting rod to rotate.

[0020] By adopting the above technical solution, rotating the second connecting rod drives the first connecting rod, which is inserted into and splined with the second connecting rod, to drive the drive shaft to rotate. In addition, rotating the second bolt until it separates from the third sleeve, and then rotating the first bolt to separate it from the connecting sleeve, separates the first sleeve from the first sleeve, separates the second sleeve from the third sleeve, and inserts the third sleeve into the first sleeve. Rotating the first bolt to make it abut against the side wall of the first sleeve can shorten the overall length of the device to adapt to some narrow spaces.

[0021] Furthermore, the rotating assembly includes a drive tube sleeved on and threadedly connected to the third sleeve, a drive rod rotatably mounted inside the drive tube and coaxially arranged with the drive tube, a third bevel gear fixedly sleeved on the drive rod and located inside the drive tube, a spline shaft passing through the side wall of the drive tube and rotatably connected to the drive tube, a fourth bevel gear fixedly sleeved on the spline shaft and meshing with the third bevel gear, and a hand crank detachably connected to the spline shaft. The upper end of the drive rod is inserted into and splinedly engaged with the lower end of the second connecting rod, and a transmission groove for inserting into the spline shaft is provided through the side wall of the hand crank.

[0022] By adopting the above technical solution, rotating the hand crank causes the spline shaft connected to the hand crank, the fourth bevel gear fixed to the spline shaft, the third bevel gear meshing with the fourth bevel gear, the drive rod fixed to the third bevel gear, and the second connecting rod splined with the drive rod to all rotate, thereby realizing the operation of rotating the drive shaft.

[0023] Furthermore, an auxiliary block is fixed on the side wall of the rotating frame away from the upper clamping plate, and a stop block is fixed on the housing, with one side wall of the stop block abutting against the auxiliary block.

[0024] By adopting the above technical solution, rotating the hand crank drives the rotating frame to rotate, which in turn drives the auxiliary block fixed to the rotating frame until the other side wall of the auxiliary block contacts the other side wall of the stop block. At this time, the cutting blade cuts the cable insulation around the circumference, so that the device can be used.

[0025] In summary, the present invention has the following beneficial effects: In this application, the wire stripping mechanism can locate and strip cables with various diameters and insulation layers of various thicknesses, which increases the functionality of the device and expands its applicable range. It also reduces the frequency of changing special clamps, shortens the operation time, and helps to improve operation efficiency. Attached Figure Description

[0041] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] Example 1: As Figure 1-11As shown in the illustration, this application discloses a quick-connect hand-cranked wire stripper, comprising a housing 1, a stripping mechanism 4, a rotating mechanism 8, and an auxiliary mechanism 9. The housing 1 has a hollow internal structure. A circular through-hole communicating with the interior of the housing 1 is provided through the side wall of the housing 1, and a notch 2 communicating with the circular through-hole is provided on the side wall of the housing 1. A rotating frame 3 is rotatably mounted inside the circular through-hole of the housing 1. The rotating frame 3 includes two horizontal frames and an arc frame. The arc frame of the rotating frame 3 is rotatably connected to the circular through-hole, and the two horizontal frames of the rotating frame 3 are fixed on the arc frame. First, the cable to be stripped is passed through the notch 2 until it enters the rotating frame 3. Then, the wire stripping mechanism 4 is operated to clamp the cable to be stripped. Finally, the cable is stripped. The wire stripping mechanism 4 can locate and strip cables of various diameters and insulation thicknesses, increasing the functionality of the device and expanding its application range. It also reduces the frequency of changing special clamps, shortens the operation time, and helps to improve work efficiency.

[0043] A wire stripping mechanism 4 is mounted on the housing 1. The wire stripping mechanism 4 is used to clamp cables of various diameters and cut insulation layers of various thicknesses. The wire stripping mechanism 4 includes a clamping assembly 41, a stripping assembly 42, and a lifting assembly 43. The clamping assembly 41 includes a bidirectional screw 411, a vertical rod 412, an upper clamping plate 413, a lower clamping plate 414, and a first lifting ring 415. The bidirectional screw 411 passes through the two horizontal supports of the rotating frame 3 and is rotatably connected to the rotating frame 3. The bidirectional screw 411 has two sections of threads with opposite helices and equal pitch. The upper clamping plate 413 and the lower clamping plate 414 are respectively mounted on the two sections of threads and are threadedly connected. The vertical rod 412 is fixed between the two horizontal supports of the rotating frame 3. The upper clamping plate 413 is slidably mounted on the vertical rod 412 and threadedly connected to the bidirectional screw 411. The lower clamping plate 414 is slidably mounted on the vertical rod 412 and threadedly connected to the bidirectional screw 411. The first lifting ring 415 is fixed to the lower end of the bidirectional screw 411. After the cable enters the rotating frame 3, rotating the first lifting ring 415 drives the bidirectional screw 411 to rotate. Since both the upper clamping plate 413 and the lower clamping plate 414 are slidably fitted with the vertical rod 412, and the bidirectional screw 411 is provided with two sections of threads with opposite helices and equal pitch, the upper clamping plate 413 and the lower clamping plate 414 are respectively mounted on the two sections of threads and threadedly connected, so that the upper clamping plate 413 and the lower clamping plate 414 move closer or further away from each other, thereby realizing the clamping or loosening operation of the cable surface. By adjusting the distance between the upper clamping plate 413 and the lower clamping plate 414, cables of various outer diameters can be operated.

[0044] The wire stripping assembly 42 is used to cut the cable insulation layer. The wire stripping assembly 42 includes a blade holder 421, a blade adjusting screw 422, a second lifting ring 423, a sliding block 424, a cutting blade 425, and a first spring 426. The blade holder 421 is fixed to the lower clamping plate 414 and has an internally hollow structure. A sliding groove 5 communicating with the interior of the blade holder 421 is provided through the side wall of the blade holder 421, and a threaded through hole is provided on the side wall of the blade holder 421. The blade adjusting screw 422 is provided through the bottom of the blade holder 421 and cooperates with the blade holder 421. The second lifting ring 423 is fixed to the lower end of the blade adjusting screw 422. The sliding block 424 is rotatably mounted on the upper end of the adjusting screw 422 and slides in the tool holder 421. The cutting blade 425 is fixed on the top of the sliding block 424 and passes through the sliding groove 5. The cutting blade 425 slides in the sliding groove 5. The first spring 426 is fixed between the top of the cutting blade 425 and the inner top wall of the tool holder 421. During the upward movement of the lower clamping plate 414, the knife holder 421 fixed to the lower clamping plate 414, the knife adjusting screw 422 connected to the knife holder 421, the second lifting ring 423 connected to the knife adjusting screw 422, the sliding block 424 connected to the knife adjusting screw 422, and the cutting blade 425 connected to the sliding block 424 all rise. When the upper clamping plate 413 and the lower clamping plate 414 clamp the cable, the cutting part of the cutting blade 425 is in contact with the surface of the cable. At this time, the lifting assembly 43 is operated to drive the cutting blade 425 to rise until the cutting part of the cutting blade 425 cuts the insulation part in contact with the cable. Finally, the rotating mechanism 8 is operated to drive the rotating frame 3 to rotate, which drives the cutting blade 425 to rotate and cut the cable insulation part all around, thereby realizing the cable stripping operation. By operating the lifting distance of the cutting blade 425, cables with insulation parts of various thicknesses can be cut and stripped, expanding the application range of the device.

[0045] The lifting assembly 43 is used to drive the cutting blade 425 to rise and fall. The lifting assembly 43 includes a first set screw 431, a second set screw 432, a compression spring 433, and a steel ball 434. The first set screw 431 is threaded through and installed on the side wall of the blade holder 421. The side wall of the adjusting screw 422 has a spiral groove 6 for the first set screw 431 to pass through and slide. The second set screw 432 is threaded into a threaded through hole. The compression spring 433 is fixed to the end of the second set screw 432 near the blade holder 421, and the steel ball 434 is fixed to the side wall of the compression spring 433 near the blade holder 421. The side wall of the adjusting screw 422 has an auxiliary groove 7 for the steel ball 434 to pass through and engage. Both sides of the auxiliary groove 7 are inclined surfaces. The distance between the two inclined surfaces of the auxiliary groove 7 gradually decreases from the steel ball 434 toward the axis of the adjusting screw 422. Multiple auxiliary grooves 7 are provided and evenly distributed about the axis of the adjusting screw 422. Rotating the second lifting ring 423 drives the adjusting screw 422 to rotate. Due to the sliding engagement between the spiral groove 6 and the first set screw 431, the adjusting screw 422 can drive the second lifting ring 423, the sliding block 424, and the cutting blade 425 to rise and fall. Furthermore, each auxiliary groove 7 corresponds to a range of cable insulation depth. During the rotation of the adjusting screw 422, the steel ball 434 first changes from contact with the corresponding auxiliary groove 7 to contact with the surface of the adjusting screw 422. During this process, because the distance between the two inclined surfaces of the auxiliary groove 7 gradually decreases from the steel ball 434 toward the axis of the adjusting screw 422, the steel ball 434 gradually moves away from the adjusting screw 422. As the axis moves, the spring 433 is stressed and gradually contracts. Finally, the steel ball 434 changes from contacting the surface of the adjusting screw 422 to contacting another auxiliary groove 7. During this process, the spring 433 gradually extends and returns to its original position, driving the steel ball 434, which is fixed to the spring 433, to move towards the direction closer to the axis of the adjusting screw 422 until the steel ball 434 passes into the corresponding auxiliary groove 7. Since the steel ball 434 is made of steel, there will be a certain sound when the steel ball 434 contacts multiple auxiliary grooves 7, so that the operator can judge whether the steel ball 434 is aligned with the auxiliary groove 7, so that the operator can adjust the height of the cutting blade 425.In this embodiment, four auxiliary slots 7 are provided, and the four auxiliary slots 7 correspond to A, B, C and D respectively. A represents the peeling setting (cutting edge depth - L1), B represents the thin setting (cutting edge depth L2), which can peel off an insulation layer thickness of approximately 2.5mm-3.5mm, C represents the medium setting (cutting edge depth L3), which can peel off an insulation layer thickness of approximately 3.2mm-4.2mm, and D represents the thick setting (cutting edge depth L4), which can peel off an insulation layer thickness of approximately 4mm-5mm. The first set screw 431 is formed on the adjusting screw 422. Within the spiral groove 6, the adjustment screw 422 can only rotate clockwise (ABCD) or counterclockwise (DCBA). When the second lifting ring 423 is rotated clockwise, the adjustment screw 422 moves upward, raising the cutting edge of the cutting blade 425 and enabling the blade to feed. Therefore, during the rotation of the adjustment screw 422, the steel ball 434, under the action of the compression spring 433, is squeezed into one of the auxiliary grooves 7. Each auxiliary groove 7 corresponds to a specific setting, providing a clear sense of jerk, allowing for precise adjustment of the cutting position. Similarly, after cutting is complete, rotating the second lifting ring 423 in the opposite direction returns the setting to DCBA.

[0046] A rotating mechanism 8 is mounted on the housing 1 and is used to drive the rotating frame 3 to rotate. The rotating mechanism 8 includes a transmission assembly 81 and a drive assembly 82. The transmission assembly 81 includes a driven shaft 811, a driven gear 812, a first circular arc gear 813, a second circular arc gear 814, a drive shaft 815, and a drive gear 816. The driven shaft 811 is rotatably mounted inside the housing 1, and the driven gear 812 is fixedly sleeved on the driven shaft 811. The first circular arc gear 813 is fixedly sleeved on the circular arc frame of the rotating frame 3 and meshes with the driven gear 812. The second circular arc gear 814 is rotatably mounted on one end of the first circular arc gear 813. The other end of the second circular arc gear 814 is provided with a circular arc slot that engages with the other end of the first circular arc gear 813. The drive shaft 815 is rotatably mounted inside the housing 1. A friction pad is provided at the connection between the drive shaft 815 and the second arc gear 814. The drive gear 816 is fixedly sleeved on the drive shaft 815 and meshes with the driven gear 812. First, the cable is threaded into the rotating frame 3. Then, the second arc gear 814 is rotated until the other end of the second arc gear 814 is inserted into the other end of the first arc gear 813. At this time, the rotating mechanism 8 is operated to drive the drive shaft 815 to rotate, which will drive the drive gear 816 fixed to the drive shaft 815, the driven gear 812 meshing with the drive gear 816, the first arc gear 813 meshing with the driven gear 812, and the rotating frame 3 fixed to the first arc gear 813 to rotate, thereby realizing the operation of cutting the cable insulation.

[0047] The drive assembly 82 is used to drive the drive shaft 815 to rotate. The drive assembly 82 includes a first sleeve 821, a drive shaft 822, a first bevel gear 823, and a second bevel gear 824. The first sleeve 821 is fixed to the bottom of the housing 1. The drive shaft 822 passes through the bottom of the housing 1 and is rotatably connected to the housing 1. The lower end of the drive shaft 822 passes through the top of the first sleeve 821 and is rotatably connected to the first sleeve 821. The first bevel gear 823 is fixedly sleeved on the drive shaft 822, and the second bevel gear 824 is fixedly sleeved on the drive shaft 815 and meshes with the first bevel gear 823. The operation auxiliary mechanism 9 drives the drive shaft 822 to rotate, thereby driving the first bevel gear 823 fixed to the drive shaft 822, the second bevel gear 824 meshing with the first bevel gear 823, and the drive shaft 815 fixed to the second bevel gear 824 to rotate, thus realizing the operation of rotating the rotating frame 3.

[0048] An auxiliary mechanism 9 is mounted on the first sleeve 821 to facilitate the rotation of the drive shaft 822. The auxiliary mechanism 9 includes a connecting assembly 91, an extension assembly 92, and a rotating assembly 93. The connecting assembly 91 includes a first sleeve 911, a first connecting rod 912, a connecting sleeve 913, a first bolt 914, and a second sleeve 915. The first sleeve 911 is located below the first sleeve 821. The first connecting rod 912 is rotatably mounted inside the first sleeve 911 and coaxially arranged with it. The upper end of the first connecting rod 912 is inserted into and splined with the lower end of the drive shaft 822. The connecting sleeve 913 is fixedly sleeved on the upper end of the first sleeve 911 and inserted into the first sleeve 821. The first bolt 914 is mounted on the first sleeve 821 and abuts against the side wall of the connecting sleeve 913. The second sleeve 915 is fixedly sleeved on the lower end of the first bolt 914. Rotating the first connecting rod 912, since the upper end of the first connecting rod 912 is inserted into and splined with the lower end of the drive shaft 822, the drive shaft 822 can be driven to rotate. In addition, the setting of the extended component 92 can increase the overall length of the first sleeve 911, thereby expanding the applicability of the device.

The second bolt 923 is located on the second sleeve 915 and abuts against the side wall of the third sleeve 922. The second connecting rod 924 is rotatably installed inside the second sleeve 921 and is coaxially arranged with the second sleeve 921. The upper end of the second connecting rod 924 is inserted into the lower end of the first connecting rod 912 and splined. The third sleeve 925 is fixedly sleeved on the lower end of the second sleeve 921. Rotating the second connecting rod 924 drives the first connecting rod 912, which is inserted into and splined with the second connecting rod 924, thereby driving the drive shaft 822 to rotate. In addition, rotating the second bolt 923 until the second bolt 923 separates from the third sleeve 922, and then rotating the first bolt 914 to separate the first bolt 914 from the connecting sleeve 913, at this time, the first sleeve 911 is separated from the first sleeve 821, the second sleeve 915 is separated from the third sleeve 922, and the third sleeve 922 is inserted into the first sleeve 821. Rotating the first bolt 914 to make the first bolt 914 abut against the side wall of the first sleeve 821 can shorten the overall length of the device to adapt to some narrow spaces.

[0050] The rotating assembly 93 drives the second connecting rod 924 to rotate. The rotating assembly 93 includes a drive tube 931, a drive rod 932, a third bevel gear 933, a splined shaft 934, a fourth bevel gear 935, and a hand crank 936.

[0051] An auxiliary block 11 is fixed to the side wall of the rotating frame 3 away from the upper clamping plate 413, and a stop block 12 is fixed to the housing 1. One side wall of the stop block 12 abuts against the auxiliary block 11. Rotating the hand crank 936 causes the rotating frame 3 to rotate, which in turn drives the auxiliary block 11 fixed to the rotating frame 3 until the other side wall of the auxiliary block 11 contacts the other side wall of the stop block 12. At this time, the cutting blade 425 cuts the cable insulation around the circumference, so that the device can be used.

[0052] This application also discloses a method for using a quick-connect hand-cranked peeler, including the following steps:

[0053] S1. According to the working length required at the work site, disassemble or connect the first sleeve 911 and the second sleeve 921 to change the overall length of the tool.

[0054] S2. Insert the cable to be cut into the rotating frame 3, and operate the clamping assembly 41 to clamp the surface of the cable, so that the cutting part of the cutting blade 425 is in contact with the surface of the cable.

[0055] S3. Based on the thickness of the cable insulation layer, rotate the second lifting ring 423 to adjust the cutting depth of the cutting part of the cutting blade 425;

[0056] S4. Rotate the hand crank 936 clockwise. Under the transmission of the rotating mechanism 8, the rotating frame 3 will be driven to rotate, which will drive the cutting blade 425 to rotate along the cable cutting position and cut the insulation layer around the surface of the cable.

[0057] S5. Rotate the second lifting ring 423 in the opposite direction so that the steel ball 434 passes into the auxiliary groove 7 corresponding to the A gear. Then continue to rotate the hand crank 936 clockwise to break the insulation layer. After breaking the insulation layer, rotate the hand crank 936 counterclockwise so that the rotating frame 3 and the wire stripping mechanism 4 rotate in the opposite direction and reset.

[0058] S6. Keep the rotating frame 3 and the wire stripping mechanism 4 in the reset position, rotate the first lifting ring 415 to drive the bidirectional screw 411 to rotate, so that the upper clamping plate 413 and the lower clamping plate 414 separate from each other until they are far away from the surface of the cable, and flip the second arc gear 814 so that the lower end of the second arc gear 814 separates from the first arc gear 813, and finally the tool can be removed smoothly.

[0059] Example 2: Figure 12-14As shown, this embodiment adds a peeling assembly and a drive mechanism 15. Specifically, there are two housings 1, and the number of notches 2, the number of rotating frames 3, the number of clamping assembly groups 41, and the number of housings 1 are all equal and their positions correspond one-to-one.

The two vertical blocks 13 are respectively fixed to the two housings 1, and the electric push rod 14 is fixed to one of the vertical blocks 13, with the moving end of the electric push rod 14 fixed to the other vertical block 13.

[0060] After the cutting blade 425 completes the circumferential cutting of the cable sheath, the two sets of clamping components 41 hold the cable and are located on both sides of the cable cutting opening. Then, the electric push rod 14 works to extend its moving end, which in turn drives the vertical block 13 fixed to the moving end of the electric push rod 14 and the housing 1 fixed to the vertical block 13 to move away from the cable cutting opening. The moving clamping components 41 will clamp the outer sheath of the cable stripping section and move it until it separates from the cable metal section, thus realizing the automatic stripping operation.

Rotating one of the bidirectional screws 411 causes the fixed shaft 152 to rotate, which in turn drives the bevel gear 155 fixed to the fixed shaft 152, the bevel gear 157 meshing with the bevel gear 155, the connecting pipe 153 fixed to the bevel gear 157, and the drive block 156 fixed to the connecting pipe 153 to rotate. Under the limiting drive of the drive block 156 and the drive groove 158, the other connecting pipe 153, the other bevel gear 157, the other bevel gear 155, the other fixed shaft 152, and the other bidirectional screw 411 to rotate synchronously.
