Description

Technical Field

[0001] The present invention relates to the technical field of wire stripping, and more specifically, to an adaptive wire rotator. In addition, it also relates to an adaptive wire insulation electric stripper including the above-mentioned adaptive wire rotator. Background Art

[0002] With the development of the power grid, when a power line fails, people need to repair the power line in a timely manner to avoid the trouble of power outage for residents' lives. Therefore, the importance of live repair work is also increasing.

[0003] Among them, live repair work is also known as live working, and one of its main tasks is to perform splicing work on overhead insulated wires. Moreover, one of the main processes in the splicing work is to strip the outer sheath of the insulated wire. However, since the outer sheath of the insulated wire usually uses high-strength polyethylene material, its thickness and hardness are very large, resulting in greater danger when construction workers use wire stripping tools to strip the outer sheath of the insulated wire. At the same time, this process is also time-consuming and laborious.

[0004] In addition, because there are many standard specifications of insulated wires, and the thickness of the outer sheath of each standard specification of insulated wire is also different. Moreover, the cable factory will produce many non-standard wires during the production of insulated wires. Therefore, the types of insulated wires are numerous, and finally it becomes very difficult for the operator to perfectly strip the outer sheath of the insulated wire during live working without damaging the metal conductor inside the insulated wire.

[0005] In the prior art, the structure of the mainstream insulation stripper generally includes: a power part, a transmission part, and a stripping part. Among them, the power part mainly drives the transmission rod of the stripper to rotate by manually shaking the handle. The transmission part is mainly an insulating rod, which is a rod-shaped object that can withstand voltage and insulation, and suitable joints are provided at both ends thereof. One joint is used to connect to the power part, and the other joint is used to connect to the rotator. Therefore, when manually shaking the handle, the transmission rod can be driven to rotate, and the rotator can be driven to rotate at the same time. In addition, the stripping part is mainly a rotator, which is made of metal and is a gear rotation structure. The entire rotator is rotated by driving the rotation of the stressed gear by an external force. A blade device is installed on the rotator. When the rotator rotates, the outer sheath of the wire can be stripped.

[0006] At present, there are two ways of rotators for mainstream insulation strippers on the market. The first way is to replace the corresponding knife dies on the rotator according to the specifications of the wires for one-to-one stripping. The second way is to install a feed clamp on the rotator that can adjust the feed angle and depth. When encountering insulated wires of different specifications, adjust the feed angle and depth for stripping.

[0007] However, in the first way, since different specifications of knife dies need to be replaced and there are a variety of knife dies, there is a problem of inconvenient carrying. Moreover, during the process of electrical construction, it is difficult to judge the specifications of the insulated wires in the air, which ultimately makes it inconvenient to replace the corresponding knife dies for construction. In the second way, since the feed angle and depth need to be adjusted, there are easily phenomena such as excessive feed depth damaging the metal conductor or too shallow feed depth resulting in incomplete stripping of the insulation layer, so there is also a problem of inconvenient construction.

[0008] In summary, how to provide a device that is simple to operate and can perform stripping operations safely and efficiently is an urgent problem for those skilled in the art at present. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide an adaptive wire rotator, which has the advantages of simple operation, can safely and efficiently strip wires, and does not require die replacement or manual tool debugging during this process.

[0010] Another purpose of the present invention is to provide an adaptive wire insulation electric stripper including the above-mentioned adaptive wire rotator, which can safely and efficiently strip wires, does not require die replacement or manual tool debugging, and can support glove operation and pole operation.

[0011] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0012] An adaptive wire rotator, comprising: a joint device that can rotate and is used to connect with an electric main body or a transmission rod, a wire clamping fixture device that is movable and arranged on the joint device for clamping wires, a fixture torque setting device that can rotate and is used to adjust the clamping degree of the wire clamping fixture device, and a tool device for stripping the insulation sheath of the wire. The wire clamping fixture device is connected through the fixture torque setting device, and the joint device can drive the wire clamping fixture device and the fixture torque setting device to rotate;

[0013] The tool device includes a tool rest device provided on the wire clamping fixture device for stripping the insulating sheath, and a tool rest guiding device for restricting the movement track of the tool rest device. The tool rest guiding device is provided on the fixture torque setting device and is connected to the tool rest device in a penetrating manner. The tool rest guiding device is provided with a slope so that the tool rest device cuts the insulating sheath at a preset inclination angle;

[0014] The fixture torque setting device is provided with a locking member for locking the fixture torque setting device so that the tool rest device can maintain cutting the insulating sheath at the preset inclination angle.

[0015] Preferably, the wire clamping fixture device includes an upper fixture and a lower fixture. The fixture torque setting device includes a rotatable lead screw that penetrates through the upper fixture and the lower fixture. The upper fixture and the lower fixture are both provided with inclined threads that match the size of the lead screw so that when the lead screw rotates clockwise or counterclockwise, the upper fixture and the lower fixture approach or move away from each other.

[0016] Preferably, the tool rest device includes a tool rest that penetrates through the upper fixture, and the tool rest can move along with the upper fixture;

[0017] One end of the tool rest is provided with a blade for cutting the insulating sheath and a blade seat for fixing the blade. The blade is connected to the blade seat, and the blade seat is slidably provided at one end of the tool rest. The upper fixture is provided with an inclined groove, and the inclination angle of the inclined groove is the same as the preset inclination angle. The blade seat is provided with a guiding member, and the guiding member passes through the inclined groove to restrict the sliding track of the blade seat. The other end of the tool rest is provided with an elastic member, and the elastic member is in a compressed state in the initial state to pull the tool rest to move;

[0018] The tool rest guiding device includes a tool rest guiding column that vertically penetrates through the tool rest and the wire clamping fixture device. The part of the tool rest guiding column that penetrates through the tool rest and the wire clamping fixture device is a trapezoidal guiding column. The slope of the trapezoidal slope of the trapezoidal guiding column is the same as the preset inclination angle. The tool rest contacts the trapezoidal slope of the trapezoidal guiding column so that the movement track of the tool rest is consistent with the slope of the trapezoidal guiding column.

[0019] Preferably, the cutting edge of the blade is inclined relative to the back surface of the blade so that one side of the cutting edge protrudes, and a hook-shaped groove is provided on the other side of the cutting edge to facilitate cutting off the insulating sheath.

[0020] Preferably, the fixture constant-torque device includes a U-shaped ring for manual rotation, a constant-torque member for transmitting and limiting the rotational torque, and a steel sleeve for transmitting the torque to the lead screw. The U-shaped ring and the steel sleeve are both connected to the constant-torque member, and the lead screw and the steel sleeve are non-slidably connected.

[0021] Preferably, the constant-torque member is a cylindrical ring-shaped component, and the steel sleeve is a cylindrical steel sleeve embedded in the inner peripheral surface of the constant-torque member. The constant-torque member is provided with a thimble and a spring for pressing the thimble. The steel sleeve is provided with a semi-circular groove, and the thimble is engaged with the groove. When the rotational torque exceeds the preset torque range, the thimble disengages from the groove and can slide on the steel sleeve, so that the constant-torque member can lock and slip the steel sleeve;

[0022] The steel sleeve is also provided with ramp teeth. When the U-shaped ring is rotated clockwise, the thimble can cross the ramp teeth. When the U-shaped ring is rotated counterclockwise, the thimble abuts against the right-angle surface of the ramp teeth, so that the thimble no longer slides on the steel sleeve.

[0023] Preferably, the joint device includes a worm for connecting with the electric main body or the transmission rod, a rotatable worm gear connected to the worm, a rotatable connecting rod penetratingly connected to the worm gear, a rotatable small gear penetratingly connected to the connecting rod, and a rotatable large gear meshing with the small gear. The wire clamping fixture device and the fixture constant-torque device are both fixedly connected to the rim of the large gear, and the large gear can drive the wire clamping fixture device and the fixture constant-torque device to rotate in the same direction.

[0024] Preferably, it includes a leather guide for guiding the cut insulating sheath out of the adaptive wire rotator and a leather guide frame for fixing the leather guide.

[0025] An adaptive wire insulating electric wire stripper includes a rotator for stripping the insulating sheath of a wire and a power device for driving the rotator to strip the wire. The power device includes an electric main body driven by a battery;

[0026] The electric main body is provided with a main body joint, and the main body joint can be connected to the adaptive wire rotator to directly drive the adaptive wire rotator to strip the wire. The main body joint can also be connected to an insulating transmission rod to drive the adaptive wire rotator to strip the wire through the transmission rod.

[0027] Preferably, the electric main engine includes a motor, a transmission connected to the motor, a start switch for controlling the start of the motor, a speed switch for controlling the rotation speed of the motor, and a forward and reverse switch for controlling the rotation direction of the motor. Both the motor and the main engine joint are connected to the transmission. The start switch, the speed switch, and the forward and reverse switch are all connected to the motor. The battery is connected to the motor to provide power to the motor.

[0028] When using the adaptive wire rotator provided by the present invention to strip the insulating sheath of a wire, first, the joint device needs to be connected to the electric main engine or the transmission rod. Then, the clamping wire fixture device can be separated from each other by rotating the fixture torque fixing device, so as to facilitate the insertion of wires of various specifications into the clamping wire fixture device. Then, the fixture torque fixing device is rotated in the reverse direction so that the clamping wire fixture device can approach each other to clamp the wire.

[0029] Meanwhile, when the clamping wire fixture device moves closer to each other, the tool rest device for stripping the insulating sheath provided on the clamping wire fixture device will move synchronously. However, since the fixture torque fixing device is provided with a tool rest guiding device for restricting the movement track of the tool rest device, and the tool rest guiding device has a slope, the tool rest device can move along the slope of the tool rest guiding device. In this process, the tool rest device can automatically adjust the wire diameter and can cut the insulating sheath at a preset inclination angle, so as to effectively ensure that the tool rest device only strips the insulating sheath without damaging the metal conductor.

[0030] Moreover, since the fixture torque fixing device is provided with a locking member for locking the fixture torque fixing device, after the fixture torque fixing device rotates to a certain extent, the tightness of the clamping wire fixture device cannot be adjusted anymore, that is, the relative position of the clamping wire fixture device cannot be changed anymore. In this way, the tool rest device can always cut the insulating sheath at a preset inclination angle.

[0031] Finally, the electric main engine or the transmission rod is started to make the joint device rotate, and the clamping wire fixture device and the fixture torque fixing device connected to the joint device can rotate accordingly. Also, because the tool rest device keeps cutting the insulating sheath at a preset inclination angle, finally, during this rotation process, the tool rest device can smoothly and completely strip the insulating sheath circumferentially.

[0032] In addition, the joint device of the adaptive wire rotator provided by the present invention can be directly connected to the electric main engine to support glove operation, or it can be connected to the transmission rod, and the transmission rod is connected to the electric main engine to support pole operation. Therefore, the use mode of the device can be determined according to the actual situation and actual needs.

[0033] In summary, the adaptive wire rotator provided by the present invention has the advantages of simple operation and can safely and efficiently strip wires. This process does not require changing molds or manually adjusting tools, and it supports glove operation and pole operation, that is, the adaptability and popularization of this device are relatively strong.

[0034] In addition, the present invention also provides an adaptive wire insulation electric stripper including the above-mentioned adaptive wire rotator, which can safely and efficiently strip wires without changing molds or manually adjusting tools, and supports glove operation and pole operation.

Specific embodiments

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] The core of the present invention is to provide an adaptive wire swivel, which has the advantages of simple operation, can safely and efficiently strip the wire, does not require changing the mold, and does not require manual adjustment of the tool. Moreover, the adaptability and popularization of this device are relatively strong.

[0053] Another core of the present invention is to provide an adaptive wire insulation electric stripper including the above-mentioned adaptive wire swivel, which can safely and efficiently strip the wire, does not require changing the mold, nor manual adjustment of the tool, and can support glove operation and pole operation.

[0054] Please refer to Figures 1 to 13 .

[0055] An adaptive wire rotator provided by the present invention includes: a joint device 1 that is rotatable and used to connect to an electric main machine 22 or a transmission rod 23, a wire clamping fixture device that is movable and arranged on the joint device 1 for clamping a wire, a fixture torque setting device 4 that is rotatable and used to adjust the clamping degree of the wire clamping fixture device, and a tool device for stripping the insulating sheath of the wire. The wire clamping fixture device and the fixture torque setting device 4 are connected through and through. The joint device 1 can drive the wire clamping fixture device and the fixture torque setting device 4 to rotate;

[0056] The tool device includes a tool rest device arranged on the wire clamping fixture device for stripping the insulating sheath and a tool rest guiding device for restricting the movement track of the tool rest device. The tool rest guiding device is arranged on the fixture torque setting device 4 and is connected through and through with the tool rest device. The tool rest guiding device is provided with a slope so that the tool rest device cuts the insulating sheath at a preset inclination angle;

[0057] The fixture torque setting device 4 is provided with a locking member for locking the fixture torque setting device 4 so that the tool rest device can maintain cutting the insulating sheath at a preset inclination angle.

[0058] It should be noted that when using the adaptive wire rotator provided by the present invention, only need to lock the wire by the wire clamping fixture device. During the locking process, the wire clamping fixture device will automatically adjust the feed angle and depth of the tool device according to the clamping tightness. This is because the specifications of the insulated wires are different and the wire diameters are also different, so that the clamping degree of the wire clamping fixture device is also different during the locking process. Therefore, with the change of the tightness of the wire clamping fixture device, the feed angle and feed depth of the tool device are also changing. In this way, a function of automatic adjustment and applicable to various specifications of wires is realized. Finally, it also makes the work of the operator to strip the insulating sheath of the overhead insulated wire very simple. Only need to perform operations such as locking on this device to accurately strip the insulating sheath of the wire.

[0059] In addition, it should be noted that during the actual application process, according to the actual situation and actual needs, the structures, dimensions, specific positions, connection methods, etc. of the joint device 1, the wire clamping fixture device, the fixture torque setting device 4, and the tool device can be determined.

[0060] It also should be noted that when using the adaptive wire rotator provided by the present invention to strip the insulating sheath of the wire, first, the joint device 1 needs to be connected to the electric main machine 22 or the transmission rod 23. Then, by rotating the fixture torque setting device 4, the wire clamping fixture devices can move away from each other so as to facilitate putting various specifications of wires into the wire clamping fixture devices. Then, rotate the fixture torque setting device 4 in the reverse direction so that the wire clamping fixture devices can move closer to each other to clamp the wire.

[0061] Meanwhile, when the wire clamping fixture device moves closer to each other, the tool rest device for stripping the insulation sheath provided on the wire clamping fixture device will move synchronously. However, since the tool rest guiding device for restricting the movement track of the tool rest device is provided on the fixture torque fixing device 4, and the tool rest guiding device has a slope, the tool rest device can move along the slope of the tool rest guiding device. During this process, the tool rest device can automatically adjust the wire diameter and can cut the insulation sheath at a preset inclination angle, thereby effectively ensuring that the tool rest device only strips the insulation sheath without damaging the metal conductor.

[0062] In addition, since the fixture torque fixing device 4 is provided with a locking member for locking the fixture torque fixing device 4, after the fixture torque fixing device 4 rotates to a certain extent, the locking member can no longer adjust the tightness of the wire clamping fixture device, that is, it can no longer change the relative position of the wire clamping fixture device. In this way, the tool rest device can always maintain cutting the insulation sheath at a preset inclination angle.

[0063] Finally, by starting the electric main engine 22 or the transmission rod 23, the joint device 1 can be rotated, and the wire clamping fixture device and the fixture torque fixing device 4 connected to the joint device 1 can rotate accordingly. Also, because the tool rest device maintains cutting the insulation sheath at a preset inclination angle, ultimately, during this rotation process, the tool rest device can smoothly and completely circumferentially strip the insulation sheath.

[0064] In addition, the joint device 1 of the adaptive wire rotator provided by the present invention can be directly connected to the electric main engine 22 to support glove operation, or it can be connected to the transmission rod 23, and the transmission rod 23 is connected to the electric main engine 22 to support rod operation. Therefore, this device can determine the usage mode of the device according to the actual situation and actual needs.

[0065] In summary, the adaptive wire rotator provided by the present invention has the advantages of simple operation, can safely and efficiently strip the wire. During this process, there is no need to change the mold, nor manually debug the tool, and it can support glove operation and rod operation, that is, the adaptability and popularization of this device are relatively strong.

[0066] Based on the above-mentioned adaptive wire rotator, preferably, the wire clamping fixture device includes an upper fixture 2 and a lower fixture 3, and the fixture torque fixing device 4 includes a rotatable lead screw 5. The lead screw 5 penetrates through the upper fixture 2 and the lower fixture 3, and both the upper fixture 2 and the lower fixture 3 are provided with inclined threads that match the size of the lead screw 5, so that when the lead screw 5 rotates clockwise or counterclockwise, the upper fixture 2 and the lower fixture 3 move closer to or away from each other.

[0067] Preferably, the fixture torque fixing device 4 can be provided with a lead screw seat for fixing the position of the lead screw 5 to ensure the rotation effect of the lead screw 5.

[0068] Therefore, the lead screw 5 can be rotated counterclockwise first to move the upper fixture 2 away from the lower fixture 3, so as to facilitate the insertion of wires with different specifications and sizes between the upper fixture 2 and the lower fixture 3. After the wire is inserted, the lead screw 5 is rotated clockwise to move the upper fixture 2 closer to the lower fixture 3, so as to clamp the wire. Since the fixture torque fixing device 4 is also provided with a locking member for locking the fixture torque fixing device 4, it can effectively prevent the upper fixture 2 and the lower fixture 3 from being too close to each other and clamping the wire too tightly, which may affect the cutting effect of the tool device.

[0069] In the actual application process, the structures, sizes, positions, etc. of the upper fixture 2, the lower fixture 3, and the lead screw 5 can be determined according to the actual situation and actual requirements.

[0070] Based on the above-mentioned adaptive wire rotator, preferably, the tool rest device includes a tool rest penetrating through the upper fixture 2, and the tool rest can move along with the upper fixture 2;

[0071] One end of the tool rest is provided with a blade 7 for cutting the insulating sheath and a blade seat 8 for fixing the blade 7. The blade 7 is connected to the blade seat 8. The blade seat 8 is slidably arranged at one end of the tool rest. The upper fixture 2 is provided with an inclined groove 9, and the inclination angle of the inclined groove 9 is the same as the preset inclination angle. The blade seat 8 is provided with a guiding member, and the guiding member passes through the inclined groove 9 to limit the sliding track of the blade seat 8. The other end of the tool rest is provided with an elastic member 10, and the elastic member 10 is in a compressed state in the initial state to pull the tool rest to move;

[0072] The tool rest guiding device includes a tool rest guiding column 11 vertically penetrating through the tool rest and the wire clamping fixture device. The part of the tool rest guiding column 11 passing through the tool rest and the wire clamping fixture device is a trapezoidal guiding column, and the slope of the trapezoidal slope of the trapezoidal guiding column is the same as the preset inclination angle. The tool rest contacts the trapezoidal slope of the trapezoidal guiding column so that the movement track of the tool rest is consistent with the slope of the trapezoidal guiding column.

[0073] It should be noted that the connection relationship and structural schematic diagram between the tool rest device and the upper fixture 2 can be referred to Figure 3 . Preferably, the tool rest can be installed on one side of the upper fixture 2 close to the lower fixture 3 to facilitate the blade 7 to cut the insulating sheath.

[0074] The tool rest can also be arranged on one side of the lower fixture 3 close to the upper fixture 2. Therefore, in the actual application process, the position of the tool rest can be determined according to the actual situation and actual requirements.

[0075] Preferably, the tool rest can include a square-column tool rest for placing the blade 7 and the blade seat 8 and a cylindrical tool rest provided with the elastic member 10. In addition, the elastic member 10 can include a spring for connecting to the tail of the cylindrical tool rest and a spring cap for pressing the spring. The spring generates potential energy under the compression of the spring cap, so that the tool rest is subjected to a backward pulling force.

[0076] Preferably, the cylindrical tool holder passes through the upper fixture 2, and the tool holder guide post 11 vertically penetrates through the cylindrical tool holder, the upper fixture 2, and the lower fixture 3. Among them, the part of the tool holder guide post 11 passing through the cylindrical tool holder is a trapezoidal guide post. Therefore, when the lead screw rotates to drive the upper fixture 2 to move, the upper fixture 2 can drive the tool holder to move synchronously. For example, when the lead screw 5 rotates clockwise, the upper fixture 2 and the lower fixture 3 can move closer to each other along the lead screw 5. During the rotation, the upper fixture 2 and the lower fixture 3 move up and down along the lead screw 5.

[0077] The tool holder guide post 11 fixes the movement directions of the upper fixture 2, the lower fixture 3, and the tool holder. The tool holder guide post 11 is fixed, and the lead screw 5 only rotates circumferentially. While the tool holder moves up and down along the tool holder guide post 11, the tool holder contacts the trapezoidal slope of the tool holder guide post 11 under the dual actions of the backward pulling force of the spring and the driving of the upper fixture 2, so that the movement track of the tool holder is consistent with the slope of the tool holder guide post 11.

[0078] Preferably, the cutting blade 7 is installed on the blade seat 8, and a horizontal double "V" - shaped track connection is provided between the blade seat 8 and the tool holder. Therefore, the blade seat 8 can slide along the track on the tool holder. A guide member can be set on each side of the blade seat 8, and the guide member passes through the inclined slot 9 of the upper fixture 2, so as to limit the sliding direction and sliding track of the blade seat 8. Therefore, when the tool holder moves up and down, the blade seat 8 also has a horizontal movement along the inclined slot 9 of the upper fixture 2.

[0079] Through the above settings, the tool holder can automatically adjust the best feed position for cutting the insulating sheath during the process of clamping the wire, so that the cutting blade 7 can cut into the insulating sheath at a preset inclination angle.

[0080] Preferably, through the collection of a large amount of relevant experimental data, it is obtained that when the preset inclination angle is 22°, the cutting effect of the tool device on the insulating sheath is the best. Therefore, the preset inclination angle can be set to 22°.

[0081] Preferably, a cut - off position can also be provided at a distance of 0.8 mm between the cutting blade 7 and the wire conductor to prevent the cutting blade 7 from cutting too deep and damaging the metal conductor.

[0082] It should be noted that the inclination angle refers to the angle between the starting point where the cutting blade 7 cuts into the insulating layer and the perpendicular line of the wire being 22°. Of course, in the actual application process, the preset inclination angle and the cut - off position can be determined according to the actual situation and actual needs.

[0083] Based on the above-mentioned adaptive wire rotator, preferably, the cutting edge of the blade 7 is inclined relative to the back surface of the blade 7, so that one side of the cutting edge protrudes, and a hook-shaped groove is provided on the other side of the cutting edge to facilitate cutting the insulating sheath. The structural schematic diagram of the blade 7 can be referred to Figure 4 and Figure 5 .

[0084] Preferably, the cutting edge and the back of the knife can be set at an angle of 3°, so that one side of the cutting edge protrudes. The protruding side of the cutting edge can first contact the cutting surface, so as to reduce the cutting resistance and make it easier to penetrate into the insulating sheath. And a groove in the shape of a hook knife is provided on the other side of the cutting edge in order to better cut the insulating sheath through the groove in the shape of a hook knife, so as to effectively separate the insulating sheath and the metal conductor.

[0085] Preferably, the blade 7 with good cutting effect and long service life can be made by machining and quenching the PM30 material, which will be beneficial to improving the peeling effect of the device.

[0086] During the actual operation process, the structure, material, shape, size, etc. of the blade 7 can be determined according to the actual situation and actual needs.

[0087] Based on the above-mentioned adaptive wire rotator, preferably, the fixture constant-torque device 4 includes a U-shaped ring 12 for manual rotation, a constant-torque part 13 for transmitting and restricting the rotation torque, and a steel sleeve 14 for transmitting the torque to the lead screw 5. The U-shaped ring 12 and the steel sleeve 14 are both connected to the constant-torque part 13, and the lead screw 5 and the steel sleeve 14 are non-slidingly connected.

[0088] Preferably, the constant-torque part 13 is a cylindrical ring-shaped component, the steel sleeve 14 is a cylindrical steel sleeve 14 embedded in the inner peripheral surface of the constant-torque part 13. The constant-torque part 13 is provided with a thimble 15 and a spring for pressing the thimble 15. The steel sleeve 14 is provided with a semi-circular groove, and the thimble 15 is clamped with the groove. When the rotation torque exceeds the preset torque range, the thimble 15 disengages from the groove and can slide on the steel sleeve 14, so that the constant-torque part 13 can lock and slip the steel sleeve 14; the steel sleeve 14 is also provided with a ramp tooth. When the U-shaped ring 12 is rotated clockwise, the thimble 15 can cross the ramp tooth. When the U-shaped ring 12 is rotated counterclockwise, the thimble 15 abuts against the right-angle surface of the ramp tooth, so that the thimble 15 no longer slides on the steel sleeve 14. At this time, the constant-torque part 13 can drive the steel sleeve 14 to rotate in the same direction, and the steel sleeve 14 will also drive the lead screw to rotate in the same direction, thus achieving the effect of counterclockwise locking and no longer slipping. The structural schematic diagram of the fixture constant-torque device 4 can be referred to Figure 6 .

[0089] Therefore, the fixture torque fixing device 4 can make the clamping degree between the upper fixture 2 and the lower fixture 3 appropriate, and they will not be clamped to each other indefinitely. When the clamping degree between the upper fixture 2 and the lower fixture 3 is appropriate, when the U-shaped ring 12 is rotated further, it will slip and cannot clamp the upper fixture 2 and the lower fixture 3 any more. In this way, it can ensure that the tool rest is maintained at a preset inclination angle, thus ensuring the feed angle of the blade 7 for cutting the insulating sheath. That is to say, it is beneficial to ensure that during the subsequent cutting process, the blade 7 always cuts the insulating sheath at a preset inclination angle, and finally the peeling effect of the device can be effectively guaranteed.

[0090] During the actual application process, the structure, shape, size, etc. of the fixture torque fixing device 4 can be determined according to the actual situation and actual requirements, so as to ensure that the blade 7 can cut the insulating sheath at a preset inclination angle.

The wire clamping fixture device and the fixture torque fixing device 4 are both fixedly connected to the rim of the large gear 20, and the large gear 20 can drive the wire clamping fixture device and the fixture torque fixing device 4 to rotate in the same direction. The structural schematic diagram of the joint device 1 is as Figure 8 shown.
