Description

Technical Field

[0001] The invention relates to the field of insulating tools for operating live equipment, and in particular to an insulating baffle for preventing accidental touching during live working. Background Art

[0002] In order to ensure reliable power supply and improve power supply quality, the provincial power grid company is now vigorously promoting distribution network non-stop operation, that is, live operation. The so-called live operation refers to a method of maintenance and testing of high-voltage electrical equipment without power outage.

[0003] Electrical equipment needs to be frequently tested, inspected and repaired during long-term operation. Live working is an effective measure to avoid power outages for maintenance and ensure normal power supply. The content of live working can be divided into live testing, live inspection and live maintenance. The objects of live working include electrical equipment in power plants and substations, overhead transmission lines, distribution lines and distribution equipment. The main items of live working are: live replacement of line tower insulators, cleaning and replacement of insulators, water washing of insulators, crimping and repairing conductors and overhead ground wires, detecting bad insulators, testing and replacing disconnectors and lightning arresters, and testing transformer temperature rise and dielectric loss values.

[0004] Live work can be divided into three categories according to the relationship between the human body and the charged body: equipotential work, ground potential work and intermediate potential work. During equipotential work, the human body directly contacts the high-voltage live parts. A human body in a high-voltage electric field will have dangerous current flowing through it, endangering personal safety. Therefore, all workers entering the high-voltage field should wear a full set of qualified shielding clothing, including clothes, shoes, socks, hats and gloves. The electrical connection between the various parts of the full set of shielding clothing must be good, and the resistance between the farthest ends cannot be greater than 20Ω, so that the human body surface forms an equipotential body. During ground potential work, the human body is on a grounded tower or frame, and live work is performed through insulating tools, so it is also called the insulating tool method. When working with live electricity on electrical equipment of different voltage levels, the minimum distance of the air gap and the minimum length of the insulating tool must be maintained. When determining the safe distance and insulation length, the system operation overvoltage and the lightning overvoltage when the lightning falls in the distance should be considered. Intermediate potential work is to enter a certain area in the high voltage electric field through tools such as insulating rods, but not directly contact the high voltage live body, which is an intermediate condition between the first two operations. Therefore, the corresponding basic safety requirements of the first two operations must be considered during intermediate potential work.

[0005] During live work, especially in ground potential work such as distribution transformer construction, construction workers often climb too high and touch the live wires on the upper layer due to carelessness, resulting in safety accidents. Therefore, a protective device to prevent accidental touching of wires is urgently needed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an insulating baffle to prevent accidental touching of live working, which can prevent construction workers from climbing too high and accidentally touching the live lines on the upper layer of the tower due to carelessness, thereby ensuring the safety of construction work.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: an insulating baffle for preventing accidental touching during live working, comprising an insulating wire clamp and an insulating guard plate, the wire clamp being detachably connected to the guard plate, the wire clamp being located above the guard plate, the number of the wire clamps being more than two and being arranged at intervals along the center line of the guard plate, the wire clamp having a clamping opening, and the clamping opening being aligned along a straight line.

[0008] Further: a connecting ring is arranged on the edge of the guard plate.

[0009] Further: a handle is provided on the midline of the lower surface of the guard plate.

[0010] Further: a boss is provided on the upper surface of the guard plate, a wedge-shaped groove is provided inside the boss, the wire clamp is formed of two clamp bodies through a rotating shaft to form a scissor-type structure, the clamp body includes an end and a wedge-shaped handle, the ends of the two mutually fitting clamp bodies are put together to form the clamping opening, and the handles of the two mutually fitting clamp bodies are put together to form a wedge-shaped body adapted to the wedge-shaped groove.

[0011] Furthermore: a connecting rod perpendicular to the rotating shaft is connected to the rotating shaft, and the handles of the two mutually matching clamping bodies are put together to form a connecting rod groove for accommodating the connecting rod.

[0012] Further: the shape of the wedge-shaped groove is trapezoidal.

[0013] Further: a turntable perpendicular to the connecting rod is rotatably connected to the end of the connecting rod, a turntable is fixedly connected to the lower surface of the turntable, a fan-shaped block is arranged at the edge of the turntable, a turning groove for accommodating the turntable is arranged inside the guard plate below the wedge-shaped groove, and a fan-shaped opening slightly larger than the outer contour of the fan-shaped block is arranged between the turning groove and the lower surface of the guard plate.

[0014] Furthermore: the clamping opening is a circular hole, and the inner diameter of the clamping opening is greater than the maximum width of the wedge-shaped body.

[0015] Further: a clamp neck is arranged at the clamp body portion between the clamp opening and the rotating shaft.

[0016] Further: an insulating rubber plate is arranged on the inner wall of the clamping opening.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0018] 1. The inventor of the present invention has keenly discovered the potential safety hazard of accidentally touching live wires at high places when climbing poles during current live working. Because when workers are working on a low-lying work surface, due to the intensity of live working, their attention will unconsciously be highly focused on the work, thus ignoring the live wires that may exist at high places, which can easily lead to safety accidents of accidentally touching live wires when moving, especially when climbing. Therefore, the present invention has innovatively proposed a solution of using practical baffles to prevent workers from accidentally touching live wires at high places, so that even after wearing basic protective equipment, construction workers can further eliminate major safety hazards caused by accidents.

[0019] 2. The present invention provides a technical solution including an insulating wire clamp and an insulating guard plate, the wire clamp and the guard plate are detachably connected, the wire clamp is located above the guard plate, the number of the wire clamps is more than two and they are arranged at intervals along the center line of the guard plate, the wire clamp has a clamping opening, and the clamping opening is aligned along a straight line, so that the device can be hung on the live line above the construction personnel's head. Because the device is provided with a wire clamp and a guard plate, and the wire clamp is located above the center line of the guard plate, the center of the entire device is just below the wire clamp, and after the wire clamp is hung on the cable, the entire device achieves a balanced posture similar to a hanger, and this posture makes the guard plate always face downward. Placed horizontally, it can effectively prevent the personnel below from accidentally touching the live wires above. In addition, even if the operator suddenly climbs up and touches the guard plate, since it is usually not directly below the center of the device, the guard plate will swing accordingly with the personnel's body upward, so as to always push the cable away from the personnel. On the one hand, this protects the personnel from electric shock, and on the other hand, it will not excessively prevent the movement trend of the personnel's body, such as accidental injuries such as bumping the head. When the movement of the body is unexpectedly hindered, the personnel may be frightened, and then other excessive posture adjustments may be made, and such excessive movements may make the center of gravity of the climbers unstable, and then there is a risk of falling. This device can effectively avoid the above problems. When the personnel touches the guard plate, it only generates a warning force feedback, and will not cause injuries or alarm to the personnel due to excessive obstruction, so it effectively improves the safety of the construction personnel's work. In addition, since this device uses a wire clamp to form a closed loop to clamp the cable, compared with hook-type solutions, it can effectively prevent the risk of falling off and falling that may occur after the personnel accidentally touch the guard plate, so it is more reliable.

[0020] 3. The present invention adopts a technical solution of providing a connecting ring on the edge of the guard plate, so that when there are multiple live cables with a distance between them above the head of the operator, multiple devices can be connected horizontally to prevent the situation where the operator is prevented from accidentally touching one cable but may accidentally touch other adjacent cables, thereby further improving the safety performance of the device and eliminating hidden dangers.

[0021] 4. The present invention adopts a technical solution in which a handle is arranged on the center line of the lower surface of the guard plate, so that the device can be held and operated by the handle located below the guard plate. This not only improves the operating convenience of the equipment, but also effectively reduces the possibility that the operator accidentally touches the live cables above the guard plate when installing the device, thereby protecting the safety of personnel and improving the overall safety performance of the equipment.

[0022] 5. The present invention provides a boss on the upper surface of the guard plate, a wedge-shaped groove inside the boss, the wire clamp is formed of two clamp bodies through a rotating shaft to form a scissor-type structure, the clamp body includes an end and a wedge-shaped handle, the ends of the two mutually matching clamp bodies are put together to form the clamping opening, and the handles of the two mutually matching clamp bodies are put together to form a wedge-shaped body matched with the wedge-shaped groove. The technical scheme allows the wire clamp of the device to have a self-locking function. Because the wire clamp has a scissor-type structure, its wedge-shaped handle cooperates with the wedge-shaped groove. Under the action of the gravity of the guard plate itself, the groove wall of the wedge-shaped groove will squeeze the wedge-shaped handle, so that the two handles tend to be closer together. Due to the scissor-type structure, the clamping opening is finally merged more tightly, thereby reducing the risk of the cable escaping from the gap between the two clamp bodies.

[0023] 6. The present invention adopts a technical solution in which a connecting rod perpendicular to the rotating shaft is arranged on the rotating shaft, and the handles of two mutually matching clamping bodies are put together to form a connecting rod groove for accommodating the connecting rod, so that the device can control the opening and closing of the wire clamp through the connecting rod on the lower surface of the guard plate. In particular, because the wire clamp has a self-locking function, when you want to change the wire clamp from a tightened state to an open state, a large force will be required. After the connecting rod is arranged, the wire clamp can be loosened by pulling the connecting rod, which not only increases the operability of the equipment, but also because all operations are performed under the guard plate, it avoids the problem of operators accidentally touching the live wire when disassembling the device.

[0024] 7. The present invention adopts a technical solution of setting the shape of the wedge-shaped groove to be trapezoidal, so that the wire clamp will not rotate arbitrarily because the wedge-shaped groove has no rotation space, and the clamp mouth can always be kept facing the required direction, that is, set along the center line direction of the guard plate, thereby ensuring the balanced posture of the equipment during operation and improving the working reliability of the device; and because the direction of the clamp mouth will not move randomly, it is also convenient for disassembly and assembly operations.

[0025] 8. The present invention further improves the locking firmness of the wire clamp by arranging a rotating disk perpendicular to the connecting rod at the end of the connecting rod, a rotating handle fixedly connected to the lower surface of the rotating disk, a fan-shaped block at the edge of the rotating disk, a rotating groove for accommodating the rotating disk inside the guard plate below the wedge-shaped groove, and a fan-shaped opening slightly larger than the outer contour of the fan-shaped block between the rotating groove and the lower surface of the guard plate. In addition to the self-locking ability of the wire clamp, the corresponding rotating disk and rotating groove are arranged to further clamp the wire clamp, which can prevent the wire clamp from accidentally falling out due to a violent impact. The arrangement of the fan-shaped block and the fan-shaped opening, in conjunction with the operation of the rotating disk and the rotating handle, can quickly open, close, disassemble and assemble the wire clamp, thereby improving the efficiency of the operation.

[0026] 9. The present invention adopts the technical solution of setting the clamping opening as a round hole and the inner diameter of the clamping opening being larger than the maximum width of the wedge-shaped body, so that the clamping opening of the device can be opened automatically. Because the inner diameter of the clamping opening is larger than the maximum width of the wedge-shaped body, the center of gravity of the clamping ring at the clamping opening will be further outward relative to the handle. In the case of relatively uniform material thickness, after the wedge-shaped handle leaves the wedge-shaped groove, the scissor-type wire clamp will open automatically because the center of gravity of the upper end is further outward, thereby improving the ease of use of the device and facilitating operation. In addition, the clamping opening is set as a round hole, which can make the wire clamp have an automatic centering effect after clamping the cable, thereby ultimately making the balance posture of the device more stable.

[0027] 10. The present invention provides a clamp neck at the clamp body between the clamp and the shaft, so that the clamp can open wider. In order to open, the clamp needs to be disengaged from the wedge groove downwards, but if the clamp ring is too close to the boss, it will block the clamp's downward movement, making the clamp's opening smaller. Therefore, the clamp neck is provided to increase the distance from the clamp to the shaft, so that the clamp can open wider, and can hold thicker cables, thereby improving the applicability of the device.

[0028] 11. The present invention adopts a technical solution of arranging an insulating rubber plate on the inner wall of the clamping opening, so that the device can enhance the insulation of the wire clamp on the one hand, and because the friction coefficient of the rubber plate is relatively large, the possibility of the device sliding along with the cable after being installed on the cable can be reduced, thereby ensuring the normal working state of the equipment.

[0038] In addition, many specific details are set forth in the following description to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0041] In the description of the present application, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, vertical, horizontal" and "top, bottom" is usually based on the coordinate system shown in the main view of the device itself or the corresponding sub-component, and when discussing other directional views, the coordinate system will not rotate accordingly. In addition, for rod-shaped or long strip-shaped components, "front end" and "head" are nouns with the same meaning, while "rear end" and "tail end", "end" and other nouns have the same meaning. The above-mentioned directional nouns are only for the convenience of describing the present application and simplifying the description. In the absence of contrary or specific instructions, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; in addition, the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0042] In addition, for ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0043] It should also be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meanings, especially there are no specific meanings of "primary" or "secondary" or arrangement order, and therefore cannot be understood as limiting the scope of protection of this application.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] like Figures 1 to 6 As shown, the structure of the present invention is generally plate-shaped, and its basic part includes an insulating wire clamp 1 and an insulating guard plate 4, the wire clamp 1 is detachably connected to the guard plate 4, the wire clamp 1 is located above the guard plate 4, the number of the wire clamps 1 is more than two and they are arranged at intervals along the center line of the guard plate 4, and the wire clamp 1 has a clamping opening, which is aligned along a straight line.

[0046] It should be noted that the protective plate 4 can be made of an insulating material as a whole, or the protective plate 4 can be divided into a main board body 10 and a board insulating layer attached to the upper surface of the main board body 10. In this way, the protective plate 4 as a whole is not limited by the insulating material, so that a preferred material with higher strength or lighter weight can be used to manufacture the protective plate 4, thereby improving the performance of the equipment.

[0047] The present invention makes up for the safety loophole of accidentally touching live wires at high places when climbing poles during current live working. Because when workers are working on a work surface at a low place, due to the tension of live working, their attention will unconsciously be highly focused on the work, thus ignoring the live wires that may exist at high places, which can easily lead to safety accidents of accidentally touching live wires when moving, especially when climbing. Therefore, the present invention innovatively proposes a solution of using practical baffles to prevent workers from accidentally touching live wires at high places, so that even after wearing basic protective equipment, construction workers can further eliminate major safety hazards caused by accidents.

[0048] In addition, since the device is provided with a wire clamp 1 and a guard plate 4, and the wire clamp 1 is located above the center line of the guard plate 4, the center of the entire device is just below the wire clamp 1, so that after the wire clamp 1 is hung on the cable, the entire device obtains a balanced posture similar to a hanger. This posture allows the guard plate 4 to always be placed horizontally facing downward, which can effectively prevent people below from accidentally touching the live wires above. In addition, even if the operator suddenly climbs up and touches the guard plate 4, since it usually does not hit it just below the center of the device, the guard plate 4 will swing accordingly as the person's body moves upward, thereby always pushing the cable away from the person. On the one hand, this protects the person from electric shock, and on the other hand, it will not excessively prevent the person's body movement tendency, such as no accidental injury from hitting the head. When the person's body movement is accidentally hindered, he may be frightened, and then he may make other excessive posture adjustments. Such excessive movements may make the center of gravity of the climber unstable, and then there is a risk of falling. The present device can effectively avoid the above problems. When a person touches the guard plate 4, only a force feedback for warning effect is generated, and the person will not be injured or alarmed due to excessive obstruction, thus effectively improving the working safety of the construction workers.

[0049] In addition, since the device uses a wire clamp 1 to form a closed loop to clamp the cable, compared with hook-type solutions, it can effectively prevent the risk of falling off or falling that may occur after a person accidentally touches the guard plate 4, and is therefore more reliable.

[0050] like Figures 3 to 5 As shown, the present invention may further provide a connecting ring 9 on the edge of the guard plate 4 .

[0051] This arrangement allows the device of the present invention to be able to connect multiple devices horizontally when there are multiple live cables with spaces between them above the heads of operators, thereby preventing the operator from accidentally touching one cable but accidentally touching other adjacent cables, further improving the safety performance of the device and eliminating hidden dangers.

[0052] like Figure 3 and Figure 5 As shown, the present invention can further provide a handle 6 on the midline of the lower surface of the guard plate 4 .

[0053] This arrangement allows the device of the present invention to be operated by holding the handle 6 located below the guard plate 4, which not only improves the operating convenience of the equipment, but also effectively reduces the possibility of operators accidentally touching the live cables above the guard plate 4 when installing the device, thereby protecting personnel safety and improving the overall safety performance of the equipment.

[0054] like Figures 1 to 6As shown, the present invention can further be provided with a boss 12 on the upper surface of the guard plate 4, and a wedge-shaped groove 16 is provided inside the boss 12. The wire clamp 1 is formed of two clamp bodies through a rotating shaft 13 to form a scissor-type structure. The clamp body includes an end and a wedge-shaped handle 3. The ends of the two mutually fitting clamp bodies are put together to form the clamping opening, and the handles 3 of the two mutually fitting clamp bodies are put together to form a wedge-shaped body adapted to the wedge-shaped groove 16.

[0055] Such a configuration enables the wire clamp 1 of the device of the present invention to have a self-locking function, because the wire clamp 1 has Figure 6 In the scissor-type structure shown, the wedge-shaped handle 3 cooperates with the wedge-shaped groove 16. Under the action of the gravity of the guard plate 4 itself, the groove wall of the wedge-shaped groove 16 will squeeze the wedge-shaped handle 3, so that the two handles 3 tend to be closer together. Due to the scissor-type structure, the clamps are eventually merged tighter, thereby reducing the risk of the cable escaping from the gap between the two clamps.

[0056] like Figure 1 and Figure 6 As shown, the present invention can further connect a connecting rod 2 perpendicular to the rotating shaft 13 to the rotating shaft 13 , and the handles 3 of the two mutually matching clamping bodies are put together to form a connecting rod groove 19 for accommodating the connecting rod 2 .

[0057] Such an arrangement enables the device of the present invention to control the opening and closing of the wire clamp 1 through the connecting rod 2 on the lower surface of the guard plate 4. In particular, because the wire clamp 1 has a self-locking function, a large force is required when the wire clamp 1 is to be changed from a tightened state to an open state. After the connecting rod 2 is provided, the wire clamp 1 can be loosened by pulling the connecting rod 2, which not only increases the operability of the equipment, but also because all operations are performed under the guard plate 4, it avoids the problem of operators accidentally touching the live wires when disassembling the device.

[0058] like Figures 3 to 5 As shown, the present invention can further set the shape of the wedge-shaped groove 16 to a trapezoid. It should be noted that the trapezoid should be distinguished from the truncated cone shape. Here, the trapezoid refers to a trapezoid with a larger upper part and a smaller lower part in the longitudinal section and is not a shape of a rotating body.

[0059] Such an arrangement ensures that the device of the present invention does not have any rotation space because the wedge-shaped groove 16 does not have any rotation space, so that the wire clamp 1 will not rotate arbitrarily, and the clamp mouth can always be kept facing the desired direction, that is, along the center line direction of the guard plate 4, thereby ensuring the balanced posture of the equipment during operation and improving the working reliability of the device; and because the direction of the clamp mouth will not move randomly, it is also convenient for disassembly and assembly operations.

[0060] like Figure 1 , Figure 2 and Figure 6As shown, the present invention can further be provided with a turntable 7 rotatably connected to the end of the connecting rod 2 and perpendicular to the connecting rod 2, a turn handle 5 is fixedly connected to the lower surface of the turntable 7, a fan-shaped block 15 is provided at the edge of the turntable 7, a rotation groove 8 for accommodating the turntable 7 is provided inside the guard plate 4 located below the wedge-shaped groove 16, and a fan-shaped opening 14 slightly larger than the outer contour of the fan-shaped block 15 is provided between the rotation groove 8 and the lower surface of the guard plate 4.

[0061] With such arrangement, the device of the present invention further improves the locking firmness of the wire clamp 1. In addition to the self-locking ability of the wire clamp 1, the corresponding rotating disk 7 and rotating groove 8 are arranged to further lock the wire clamp 1, which can prevent the wire clamp 1 from accidentally falling out due to a violent impact. And the arrangement of the fan-shaped block 15 and the fan-shaped opening 14, in conjunction with the operation of the rotating disk 7 and the rotating handle 5, can quickly open, close, disassemble and assemble the wire clamp 1, thereby improving the working efficiency.

[0062] like Figure 1 and Figure 6 As shown, the present invention can further configure the clamping opening to be a circular hole, and the inner diameter of the clamping opening is greater than the maximum width of the wedge-shaped body.

[0063] The device of the present invention can realize the automatic opening of the jaws. Because the inner diameter of the jaws is larger than the maximum width of the wedge, the maximum width of the wedge is Figure 1 The width of the bottom of the middle handle 3 after merging. In this way, the center of gravity of the clamp ring 17 at the clamping mouth will be further outward relative to the handle 3. In the case of relatively uniform material thickness, after the wedge-shaped handle 3 leaves the wedge-shaped groove 16, the scissor-type wire clamp 1 will automatically open because the center of gravity of the upper end is further outward, which improves the ease of use of the device and facilitates operation. In addition, the clamping mouth is set as a round hole so that the wire clamp 1 has an automatic centering function after clamping the cable, thereby making the balance posture of the device more stable.

[0064] like Figure 1 and Figure 6 As shown, the present invention can further provide a clamp neck 20 at the clamp body portion between the clamp opening and the rotating shaft 13 .

[0065] The device of the present invention configured in this way can make the opening range of the clamp larger, because in order for the wire clamp 1 to open, the wire clamp 1 needs to be disengaged downward from the wedge-shaped groove 16, but if the clamp ring 17 is too close to the boss 12, it will block the downward movement of the wire clamp 1, making the opening range of the wire clamp 1 smaller. Therefore, the clamp neck 20 is provided to increase the distance from the clamp to the rotating shaft 13, so that the opening range of the clamp can be larger, and thicker cables can be supported, thereby improving the applicability of the device.

[0066] like Figure 1 and Figure 6As shown, the present invention can further provide an insulating rubber plate 18 on the inner wall of the clamping opening.

[0067] With such arrangement, the device of the present invention can enhance the insulation of the wire clamp 1 on the one hand, and because the friction coefficient of the rubber plate is relatively large, the possibility of the device sliding along with the cable after being installed on the cable can be reduced, thereby ensuring the normal working state of the device.

[0068] It is emphasized again that the embodiments described here are only part of the embodiments of the present invention, not all of the embodiments, and the specific embodiments described here are only used to explain the present invention, and are not used to limit the claims of the present invention. Based on the embodiments of the present invention, any obvious changes made by ordinary technicians in this field under the design concept of the present invention are within the scope of protection of the present invention.
