Description

Technical Field

[0001] The present invention relates to the field of cable steel armor cutters, and more particularly to a cable steel armor quick cutter and a use method thereof. Background Art

[0002] With the development of urban construction and the increase in large-scale residential areas, cable lines have replaced overhead lines in more occasions. The increase in cable mileage and service life has increased the probability of cable failure, especially cable head failure, including the inlet and outlet wire heads of the ring network cabinet, the elbow head of the branch box, the intermediate joint, etc.; in the process of making the cable head, the operator needs to cut the cable armor wrapped around the cable core, but the stripping of the armor is the most time-consuming and labor-intensive, and the process is also the most difficult to master. Commonly used tools include hand saws, scissors shearing and vise jaws tearing, etc. These methods are time-consuming and labor-intensive, and sometimes the working environment on site is inconvenient and the space is relatively narrow. Coupled with the problems of existing tools, this will cause the edges of the stripped armor to be uneven, with burrs, and damage the inner sheath, etc., which also brings certain safety hazards to the cable operation; and especially for cables with larger diameters, the cable core is more compact, which makes it more laborious to strip the cable armor.

[0003] In view of this, this application is hereby made. Summary of the invention

[0004] The object of the present invention is to provide a cable steel armor quick cutter and a use method to solve the problems existing in the above-mentioned background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] In a first aspect, the present application provides a cable armor quick cutter, comprising a small cutter and an annular sleeve for sleeved on the end of a cable to be stripped, wherein the small cutter is movably connected to the annular sleeve; the annular sleeve comprises an outer ring sleeve and an inner ring shrinking member, wherein the annular sleeve and the inner ring shrinking member are connected via a plurality of abutting members, wherein one end of each abutting member is fixedly connected to the inner wall of the outer ring sleeve, and the other end of each abutting member passes through the inner ring shrinking member, and the end after passing through forms an abutting member abutting against the outer wall of the cable to be stripped;

[0007] The inner ring shrinking member includes a strip belt and a connector. The strip belt is surrounded to form an annular structure, and the two ends of the strip belt are connected by the connector to form an inner ring shrinking member of a hoop structure. The diameter of the annular structure formed by the strip belt can be changed by a rotary control in the connector.

[0008] The outer ring set is provided with a notch, the small cutting machine is located in the notch and is movably connected to the strip belt, and when the diameter of the annular structure changes, the small cutting machine can reciprocate in the radial direction of the outer ring set.

[0009] The beneficial effects of the present invention are as follows: in this scheme, through the connection between the small cutting machine and the annular sleeve, the annular sleeve is sleeved on the cable to be stripped when in use, and when sleeved, the end of the cable to be stripped is sleeved in the inner ring shrinkage piece of the annular sleeve, and then the strip belt is shrunk by the rotary adjustment control on the connector, so that each abutment on the strip belt presses the end of the cable to be stripped tightly, and finally the small cutting machine is started and the annular sleeve is rotated, so as to realize cutting off the steel armor to be stripped in the cable to be stripped; and in the process of the diameter of the annular structure formed by the strip belt changing, the abutment and the small cutting machine will move with the diameter of the annular structure, that is, in the annular structure, the abutment is moved. When the diameter of the ring structure becomes larger, the abutment head and the small cutting machine will move away from the center of the ring structure, and when the diameter of the ring structure becomes smaller, the abutment head and the small cutting machine will move toward the center of the ring structure, so that the abutment head can always hold the cable to be stripped tightly, and the distance between the small cutting machine and the strip belt is always fixed, that is, the distance between the cutting blade of the small cutting machine and the strip belt is fixed, so for the same cutting blade, no matter what the diameter of the cable to be stripped in the ring is, after adjusting the diameter of the ring belt, it can be ensured that the cutting depth of the cutting blade is always consistent; and when different cutting depths need to be cut, it is sufficient to replace the cutting blade with a larger or smaller diameter.

[0010] In this solution, through the cooperation between the small cutting machine and the ring kit, the cable armor can be cut quickly, and faster and better cutting can be achieved in a smaller working space. As for the effect after cutting, the cutting depth can be consistent, and it is not easy to damage the inner sheath of the cable. At the same time, the cut surface is regular and burr-free, avoiding the time wasted by the need for secondary grinding, reducing the probability of safety problems during cable operation due to uneven cut surface, burrs, damage to the inner sheath, etc., and improving the safety of cable use.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the above-mentioned abutment member includes a sliding rod with an opening at one end and a sleeve rod, the sliding rod is located inside the sleeve rod, and the outer wall of the sliding rod is slidably connected to the inner wall of the sleeve rod; a telescopic spring is arranged inside the sliding rod, one end of the telescopic spring is fixedly connected to the top inner wall of the sliding rod, and the other end of the telescopic spring is fixedly connected to the bottom inner wall of the sleeve rod; one end of the sleeve rod away from the sliding rod is fixedly connected to the inner wall of the outer ring sleeve, and one end of the sliding rod away from the sleeve rod is fixedly connected to the abutment head.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the abutment member is composed of a retractable sliding rod and a sleeve rod, so that in actual use, after the cable is inserted into the inner ring contraction member, each abutment joint can tighten the cable to facilitate subsequent operations; and then when the inner ring contraction member is contracted, since each abutment joint has already tightened the cable, the entire device will not move when the inner ring contraction member is operated, and turning the rotary adjustment control unit is also more convenient and easy.

[0014] Furthermore, the abutment joint comprises a hemispherical connecting portion and a spherical sliding member; the arc surface of the connecting portion is arranged toward the center of the outer ring sleeve, and the sliding member is embedded in the top of the arc surface of the connecting portion.

[0015] The beneficial effect of adopting the above further solution is: a spherical sliding piece is embedded in the top of the connecting part, so that the connecting part and the cable are in rolling connection, so as to reduce friction and facilitate the movement of the whole device after the cable is sleeved.

[0016] Furthermore, one end of the connecting portion connected to the abutment member is provided with an arc transition surface that slidably cooperates with the strip belt.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that the arc transition surface set on the other side of the connecting part can be used for sliding between the connecting part and the strip band. Since the connecting part moves inside the arc of the strip band, if the end surface where the connecting part and the strip band are in contact is a horizontal plane, this will undoubtedly hinder the sliding between the two. Setting it as an arc transition surface also makes the sliding between the two smoother.

[0018] Furthermore, the strip belt is provided with a strip groove along its length direction, the small cutting machine is connected to the strip belt via a connecting piece, the connecting piece and a plurality of abutting pieces all pass through the strip groove, and a limiting piece is provided at one end of the connecting piece after passing through.

[0019] The beneficial effect of adopting the above further solution is that the provision of the strip groove ensures that when the diameter of the annular structure formed by the strip belt changes, the positions of the abutment member and the connecting member relative to the outer ring sleeve will not change.

[0020] Furthermore, both side ends of the notch extend radially inward to form guide members, and moving members are slidably connected inside the two guide members, and the moving members are connected to the small cutting machine.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that: by connecting the small cutting machine with the guide part, the small cutting machine can be moved along the radial direction of the outer ring sleeve or the annular structure during the process of the diameter of the annular structure formed by the strip band changing, that is, it moves toward or away from the center of the outer ring sleeve and the annular structure. In this way, the depth of the small cutting machine's cutting into the cable will not change without replacing the cutting blade, thereby avoiding the small cutting machine from moving to the left or right, resulting in a change in the cutting depth of the small cutting machine without replacing the cutting blade, that is, avoiding the situation where the cutting blade cannot cut the cable when the diameter of the annular structure changes, or the cutting depth becomes deeper, causing damage to the inner layer structure of the cable.

[0022] Furthermore, the number of the abutment members is three, and the three abutment members are evenly distributed in the circumferential direction of the outer ring sleeve.

[0023] The beneficial effect of adopting the above further scheme is that the angle between the three abutments is 120 degrees, so that the cable with a circular cross-section can be better clamped, and the three abutments can achieve the abutment of the top of each abutment head with the clamped cable, and the overall device is easier to move and rotate on the cable.

[0024] Furthermore, the small-sized cutting machine is equipped with a plurality of cutting blades of different diameters.

[0025] The beneficial effect of adopting the above further solution is that cutting blades with different diameters can meet the requirements of cutting depth for different types of cables.

[0026] Furthermore, the above-mentioned annular sets are provided in a group, the two annular sets are symmetrically arranged, the small cutting machine is located in the gaps opened by the two outer annular sets, and the axis of the small cutting machine is parallel to the center line connecting the two annular sets;

[0027] The rotary adjustment controls of the two connectors are coaxially arranged, and a fixing piece is arranged between the outer ring sets of the two ring sets.

[0028] The beneficial effect of adopting the above further solution is that a set of annular sets can improve the stability of the small cutting machine and can avoid the situation of shaking left and right when the annular sets rotate.

[0029] In a second aspect, the present application provides a method for using a cable steel armor quick cutter, which is applied to a cable steel armor quick cutter according to any one of the first aspects, and comprises the following specific steps:

[0030] Obtaining the diameter of the cable to be stripped, and determining the cutting depth of the cable to be stripped according to the diameter of the cable to be stripped;

[0031] According to the cutting depth, the cutting blade of the small cutting machine is replaced with a target blade with a suitable diameter size;

[0032] The diameter of the inner ring shrink piece is adjusted by the rotary control unit of the connection part, the ring set is put into the stripping end of the cable to be stripped, and the ring set is moved to the target stripping position according to the preset stripping length;

[0033] The diameter of the inner ring shrinking piece is reduced by rotating the control unit of the connecting part until each abutting piece is tightly abutted against the outer wall of the cable to be stripped;

[0034] Start the small cutting machine, adjust the stripping end of the cable to be stripped until the stripping end is perpendicular to the end face of the outer ring set, rotate the ring set around the circumference of the cable to be stripped for at least one circle until the cable armor of the cable to be stripped is stripped.

[0035] The beneficial effects of the present invention are as follows: in this scheme, through the connection between the small cutting machine and the annular sleeve, the annular sleeve is sleeved on the cable to be stripped when in use, and when sleeved, the end of the cable to be stripped is sleeved in the inner ring shrinkage piece of the annular sleeve, and then the strip belt is shrunk by the rotary adjustment control on the connector, so that each abutment on the strip belt presses the end of the cable to be stripped tightly, and finally the small cutting machine is started and the annular sleeve is rotated, so as to realize cutting off the steel armor to be stripped in the cable to be stripped; and in the process of the diameter of the annular structure formed by the strip belt changing, the abutment and the small cutting machine will move with the diameter of the annular structure, that is, in the annular structure, the abutment is moved. When the diameter of the ring structure becomes larger, the abutment head and the small cutting machine will move away from the center of the ring structure, and when the diameter of the ring structure becomes smaller, the abutment head and the small cutting machine will move toward the center of the ring structure, so that the abutment head can always hold the cable to be stripped tightly, and the distance between the small cutting machine and the strip belt is always fixed, that is, the distance between the cutting blade of the small cutting machine and the strip belt is fixed, so for the same cutting blade, no matter what the diameter of the cable to be stripped in the ring is, after adjusting the diameter of the ring belt, it can be ensured that the cutting depth of the cutting blade is always consistent; and when different cutting depths need to be cut, it is sufficient to replace the cutting blade with a larger or smaller diameter.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] In the present application, the small cutting machine is connected to the annular sleeve. When in use, the annular sleeve is sleeved on the cable to be stripped. When sleeved, the end of the cable to be stripped is sleeved in the inner ring shrinkage piece of the annular sleeve. Then, the strip belt is shrunk by the rotary adjustment control on the connector, so that each abutment on the strip belt presses the end of the cable to be stripped tightly. Finally, the small cutting machine is started and the annular sleeve is rotated, so as to cut off the steel armor to be stripped in the cable to be stripped. And in the process of changing the diameter of the annular structure formed by the strip belt, the abutment and the small cutting machine will move with the diameter of the annular structure, that is, when the diameter of the annular structure changes, the abutment and the small cutting machine will move with the diameter of the annular structure. When the diameter of the annular structure is large, the abutment head and the small cutting machine will move away from the center of the annular structure; when the diameter of the annular structure becomes smaller, the abutment head and the small cutting machine will move toward the center of the annular structure, so that the abutment head can always hold the cable to be stripped tightly, and the distance between the small cutting machine and the strip belt is always fixed, that is, the distance between the cutting blade of the small cutting machine and the strip belt is fixed. In this way, for the same cutting blade, no matter what the diameter of the cable to be stripped in the annular member is, after adjusting the diameter of the annular belt, it can be ensured that the cutting depth of the cutting blade remains consistent; when different cutting depths need to be cut, it is sufficient to replace the cutting blade with a larger or smaller diameter.

[0038] In the present application, through the cooperation between the small cutting machine and the ring kit, the cable armor can be quickly cut, and faster and better cutting can be achieved in a smaller working space. As for the effect after cutting, the cutting depth can also be consistent, and the inner sheath of the cable is not easily damaged. At the same time, the cut surface is regular and burr-free, avoiding the time wasted by secondary grinding, reducing the probability of safety problems caused by uneven cut surface, burrs, damage to the inner sheath, etc. during cable operation, and improving the safety of cable use; the abutment is composed of a retractable sliding rod and a sleeve rod, so that in actual use, after the cable is extended into the inner ring contraction part, each abutment head can tighten the cable to facilitate subsequent operations; and then when the inner ring contraction part is contracted, since each abutment head has tightened the cable, the overall device will not move when the inner ring contraction part is operated, and turning the rotary adjustment control is also more convenient and easy.

[0039] In the present application, a spherical sliding part is embedded in the top of the connecting part to make a rolling connection between the connecting part and the cable, so as to reduce friction and facilitate the movement of the overall device after the cable is sleeved; the arc transition surface arranged on the other side of the connecting part can be used when sliding occurs between the connecting part and the strip belt. Since the connecting part moves on the inner side of the arc of the strip belt, if the end surface where the connecting part and the strip belt are in contact is a horizontal surface, this will undoubtedly hinder the sliding between the two, and setting it as an arc transition surface also makes the sliding between the two smoother; the setting of the strip groove realizes that when the diameter of the annular structure formed by the strip belt changes, the position of the abutment and the connecting part will not change relative to the outer ring kit.

[0040] In the present application, the small cutting machine is connected to the guide member, so that the small cutting machine can move along the radial direction of the outer ring sleeve or the ring structure during the change of the diameter of the annular structure formed by the strip band, that is, move toward or away from the center of the outer ring sleeve and the ring structure, so that the depth of the small cutting machine cutting into the cable will not change without replacing the cutting blade, thereby avoiding the small cutting machine moving to the left or right, resulting in a change in the cutting depth of the small cutting machine without replacing the cutting blade, that is, avoiding the cutting blade from being unable to cut the cable when the diameter of the annular structure is changed, or the cutting depth becomes deeper, causing damage to the inner layer structure of the cable; the angle between the three abutments is 120 degrees, so that the cable with a circular cross-section can be better clamped, and the three abutments can realize the abutment of the top of each abutment head with the clamped cable, and the overall device is more convenient to move and rotate on the cable; cutting blades of different diameters can meet the cutting depth requirements for different types of cables.

[0057] Embodiment 1: In order to solve the problems that the stripping of cable armor wrapping the cable core is time-consuming, laborious, and difficult to master the process when the operators cut the cable armor, and the current commonly used tools such as hand saws, scissors for cutting and vise-jaw pliers for cutting are time-consuming and laborious, and the on-site working environment is inconvenient and the space is relatively narrow. At the same time, the edges of the stripped steel armor are uneven, there are burrs, and the inner sheath is damaged, which brings certain safety hazards to the operation of the cable. This embodiment provides a cable armor quick cutter, including a small cutting machine 1, and a ring-shaped kit for being sleeved on the end of the cable to be stripped, and the small cutting machine 1 is movably connected to the ring-shaped kit; the ring-shaped kit includes an outer ring kit 2 and an inner ring shrinking piece 3, and the ring-shaped kit and the inner ring shrinking piece 3 are connected by a plurality of abutment members 4, one end of each abutment member 4 is fixedly connected to the inner wall of the outer ring kit 2, and the other end of each abutment member 4 passes through the inner ring shrinking piece 3, and the end after penetration forms an abutment joint 5 that abuts against the outer wall of the cable to be stripped.

[0058] When in use, the annular sleeve is sleeved on the cable to be stripped, and when sleeved, the end of the cable to be stripped is sleeved in the inner ring shrinkage piece 3 of the annular sleeve, and then the strip belt 6 is contracted by the rotary adjustment control 8 on the connector 7, so that each abutment 5 on the strip belt 6 presses the end of the cable to be stripped, and finally the small cutting machine 1 is started and the annular sleeve is rotated, so as to cut off the steel armor that needs to be stripped in the cable to be stripped.

[0059] Optionally, the abutment member 4 includes a sliding rod 10 with an opening at one end and a sleeve rod 11, such as Figure 6As shown, the sliding rod 10 is located inside the sleeve rod 11, and the outer wall of the sliding rod 10 is slidably connected to the inner wall of the sleeve rod 11; a telescopic spring 12 is arranged inside the sliding rod 10, one end of the telescopic spring 12 is fixedly connected to the top inner wall of the sliding rod 10, and the other end of the telescopic spring 12 is fixedly connected to the bottom inner wall of the sleeve rod 11; the end of the sleeve rod 11 away from the sliding rod 10 is fixedly connected to the inner wall of the outer ring sleeve 2, and the end of the sliding rod 10 away from the sleeve rod 11 is fixedly connected to the abutment 5.

[0060] Among them, the abutment 4 is composed of a retractable sliding rod 10 and a sleeve rod 11, so that in actual use, after the cable is inserted into the inner ring contraction part 3, each abutment joint 5 can tighten the cable to facilitate subsequent operations; and then when the inner ring contraction part 3 is contracted, since each abutment joint 5 has already tightened the cable, the entire device will not move when the inner ring contraction part 3 is operated, and turning the rotary adjustment control 8 is also more convenient and easy.

[0061] Optionally, the abutment head 5 includes a hemispherical connecting portion 13 and a spherical sliding member 14 ; the arc surface of the connecting portion 13 is arranged toward the center of the outer ring sleeve 2 , and the sliding member 14 is embedded in the top of the arc surface of the connecting portion 13 .

[0062] A spherical sliding member 14 is embedded at the top of the connecting portion 13. Figure 2 , Figure 3 and Figure 6 As shown, the connection portion 13 and the cable are connected in a rolling manner to reduce friction and facilitate movement of the entire device after the cable is sleeved.

[0063] Optionally, one end of the connecting portion 13 connected to the abutment member 4 is provided with an arc transition surface 15 that slidably cooperates with the strip belt 6 .

[0064] Among them, Figure 3 and Figure 6 As shown, the arc transition surface 15 arranged on the other side of the connecting portion 13 can be used when sliding occurs between the connecting portion 13 and the strip band 6. Since the connecting portion 13 moves inside the arc of the strip band 6, if the end surface where the connecting portion 13 and the strip band 6 are in contact is a horizontal surface, this will undoubtedly hinder the sliding between the two. Setting it as an arc transition surface 15 also makes the sliding between the two smoother.

[0065] Furthermore, the above-mentioned inner ring shrinkage piece 3 includes a strip band 6 and a connector 7. The strip band 6 is surrounded to form an annular structure, and the two ends of the strip band 6 are connected by the connector 7 to form an inner ring shrinkage piece 3 with a hoop structure, and the diameter of the annular structure formed by the strip band 6 can be changed by the rotary adjustment control 8 in the connector 7.

[0066] Among them, the inner ring shrink member 3 of the hoop structure is formed by the strip band 6 and the connector 7, that is, the inner ring shrink member 3 can be obtained by improving the hoop, and the structure of the strip band 6 is as follows: Figure 4 As shown, in Figure 4 The outer wall of the strip belt 6 has a plurality of teeth and grooves arranged along its length direction to achieve a snap-fit ​​fit with the rotary adjustment control 8, that is, when the rotary adjustment control 8 rotates, the diameter of the annular structure formed by the strip belt 6 can be changed. Its structural principle is the same as that of the clamp, and will not be repeated here. The difference in structure is that the adjustment belt is penetrated by a strip groove 19, and the strip groove 19 is set to achieve the fit with the abutment 4 and the connecting member, that is, the abutment 4 and the connecting member are both penetrated by the strip groove 19, and will not affect the contraction of the strip belt 6. The material of the strip belt 6 here can be a flexible material, such as a deformable rubber belt, or a deformable metal material. For the outer ring kit 2, the annular structure formed by a hard metal material is preferred.

[0067] Optionally, the strip belt 6 is provided with a strip groove 19 along its length direction, and the small cutting machine 1 is connected to the strip belt 6 via a connecting piece, and the connecting piece and multiple abutting pieces 4 all pass through the strip groove 19, and a limiting piece 16 is provided at one end of the connecting piece after passing through.

[0068] The arrangement of the strip groove 19 ensures that the positions of the abutment member 4 and the connection member relative to the outer ring sleeve 2 will not change when the diameter of the annular structure formed by the strip band 6 changes.

[0069] Furthermore, the outer ring set 2 is provided with a notch 9, the small cutting machine 1 is located in the notch 9 and is movably connected to the strip belt 6, and when the diameter of the annular structure changes, the small cutting machine 1 can reciprocate in the radial direction of the outer ring set 2.

[0070] Optionally, both ends of the notch 9 extend radially inward to form guide members 17, and movable members 18 are slidably connected in the two guide members 17, and the movable members 18 are connected to the small cutting machine 1; specifically, the movable member 18 can be formed of an integrated plate structure, such as Figure 5 As shown, the moving member 18 may also be a plate body, which is connected to the small cutting machine 1 through the main body, such as Figure 2 shown.

[0071] Among them, the small cutting machine 1 is connected to the small cutting machine 1 through the guide member 17, so that the small cutting machine 1 can move along the radial direction of the outer ring sleeve or the ring structure during the process of the diameter of the ring structure formed by the strip belt 6 changing, that is, move toward or away from the center of the outer ring sleeve and the ring structure. In this way, the depth of the small cutting machine 1 cutting into the cable will not change without replacing the cutting blade, thereby avoiding the small cutting machine 1 moving to the left or right, resulting in a change in the cutting depth of the small cutting machine 1 without replacing the cutting blade, that is, avoiding the cutting blade from being unable to cut the cable when the diameter of the ring structure is changed, or the cutting depth becoming deeper, thereby damaging the inner layer structure of the cable.

[0072] Optionally, the number of the abutment members 4 is three, and the three abutment members 4 are evenly distributed in the circumferential direction of the outer ring sleeve 2 .

[0073] The angle between the three abutting members 4 is 120 degrees. Figure 1 and Figure 3 As shown, in this way, the cable with a circular cross-section can be better clamped, and the three abutting members 4 can achieve the abutment of the top end of each abutting head 5 with the clamped cable, and the overall device is more convenient to move and rotate on the cable.

[0074] Optionally, the small cutting machine 1 is equipped with a plurality of cutting blades with different diameters.

[0075] Among them, cutting blades with different diameters can meet the needs of cutting depth for different types of cables.

[0076] Optionally, the above-mentioned annular kit is provided in a group, and the two annular kits are symmetrically arranged, the small cutting machine 1 is located in the gap 9 opened by the two outer ring kits 2, and the axis of the small cutting machine 1 is parallel to the center line of the two annular kits; the rotary adjustment controls 8 of the two connectors 7 are coaxially arranged, and a fixing part is arranged between the outer ring kits 2 of the two annular kits.

[0077] Among them, Figure 1 As shown, a set of annular sets can improve the stability of the small cutting machine 1 and prevent the annular sets from shaking left and right when rotating.

[0078] Embodiment 2: This embodiment provides a method for using a cable steel armor quick cutter, which is applied to a cable steel armor quick cutter of any one of the first aspects, and comprises the following specific steps:

[0079] S1, obtaining the diameter of the cable to be stripped, and determining the cutting depth of the cable to be stripped according to the diameter of the cable to be stripped.

[0080] S2, according to the cutting depth, the cutting blade of the small cutting machine 1 is replaced with a target blade with a matching diameter.

[0081] S3, adjust the diameter of the inner ring shrinkage piece 3 by the rotary adjustment control 8 of the connecting part 13, insert the annular sleeve into the stripping end of the cable to be stripped, and move the annular sleeve to the target stripping position according to the preset stripping length.

[0082] S4, reducing the diameter of the inner ring shrinking member 3 by rotating the adjusting knob 8 of the connecting portion 13 until each abutting member 4 abuts against the outer wall of the cable to be stripped.

[0083] S5, start the small cutting machine 1, adjust the stripping end of the cable to be stripped until the stripping end is perpendicular to the end face of the outer ring sleeve 2, and rotate the ring sleeve around the circumference of the cable to be stripped for at least one circle until the stripping of the cable armor of the cable to be stripped is completed.

[0084] Specifically, through the connection between the small cutting machine 1 and the annular set, in actual use, when the sleeve is performed, the end of the cable to be stripped is sleeved in the inner ring shrinking piece 3 of the annular sleeve, and then the strip belt 6 is shrunk by the rotary adjustment control 8 on the connector 7, so that each abutment 5 on the strip belt 6 presses the end of the cable to be stripped tightly and then cooperates by tightening the strip belt 6, and finally the small cutting machine 1 is started and the annular set is rotated, so as to realize the cutting of the steel armor that needs to be stripped in the cable to be stripped; and especially for the problem that the current tools are difficult to operate on cables with large diameters, through this cutter and the corresponding use method, the steel armor can be easily and conveniently cut; wherein, in the process of the diameter of the annular structure formed by the strip belt 6 changing, the abutment 5 and the small cutting machine are The cutting machine 1 will move with the diameter of the annular structure, that is, when the diameter of the annular structure becomes larger, the abutment head 5 and the small cutting machine 1 will move away from the center of the annular structure, and when the diameter of the annular structure becomes smaller, the abutment head 5 and the small cutting machine 1 will move toward the center of the annular structure, so that the abutment head 5 can always press the cable to be stripped tightly, and the distance between the small cutting machine 1 and the strip belt 6 is always fixed, that is, the distance between the cutting blade of the small cutting machine 1 and the strip belt 6 is fixed, so for the same cutting blade, no matter what the diameter of the cable to be stripped in the annular member is, after adjusting the diameter of the annular belt, it can be ensured that the cutting depth of the cutting blade is always consistent; and when different cutting depths need to be cut, a cutting blade with a larger or smaller diameter can be replaced.
