[0002] In the operation and maintenance of power systems, live-line work is an important means to ensure the reliability of power supply. Among them, the separation of conductors (such as the separation of lead wires) is a common scenario. Such operations require the use of special tools to separate live conductors from lead wires, while ensuring the personal safety of the workers. Summary of the Invention

[0003] In view of this, this application provides an anti-interference circuit operating lever, the main purpose of which is to improve the safety of separating the live wire from the drain wire.

[0004] To achieve the above objectives, this application mainly provides the following technical solutions:

[0006] A first clamping assembly, comprising a first insulating rod and a first clamp, wherein the first clamp is fixedly disposed on the first insulating rod for locking the live wire;

[0007] The second clamping assembly includes a second insulating rod and a second clamp. The second clamp is movably disposed on the first insulating rod for locking the drain wire. The second insulating rod is connected to the second clamp for pushing and pulling the second clamp to move the second clamp closer to or away from the first clamp.

[0008] Optionally, the second insulating rod is arranged parallel to the first insulating rod.

[0009] Optionally, the anti-interference circuit operating lever further includes:

[0010] A guide sleeve is slidably fitted with the second insulating rod. The guide sleeve is sleeved on the outside of the second insulating rod and fixedly connected to the first insulating rod.

[0011] Optionally, the first chuck includes:

[0012] A first fixing clamp is fixedly connected to the first insulating rod and is used to provide a first fixed support surface for clamping the live wire;

[0013] A first movable clamp is movably connected to a first fixed clamp and is movable relative to the first fixed clamp to cooperate with the first fixed clamp to clamp the live wire.

[0014] Optionally, the first fixing clamp includes:

[0015] A first fixed seat is located on the side of the first fixed support surface away from the second clamping assembly. The first fixed seat is disposed opposite to the first fixed support surface, and a first path for the first movable clamping body to move is formed between the first fixed seat and the first fixed support surface. A first threaded hole is provided on the first fixed seat for threaded connection with a first screw. One end of the first screw passes through the first threaded hole, and the other end is rotatably connected to the first movable clamping body. The first screw is used to drive the first movable clamping body to move along the first path relative to the first fixed support surface by rotation, so as to adjust the clamping distance between the first fixed support surface and the first movable clamping body.

[0016] Optionally, the anti-interference circuit operating lever further includes:

[0017] The rotating ring is provided. The first screw includes a first proximal end rotatably connected to the first movable clamp and a first distal end away from the first movable clamp. The first distal end extends along the axial direction of the first screw in a direction away from the first movable clamp, and the rotating ring is fixedly connected to the first distal end.

[0018] Optionally, the second chuck includes:

[0019] The second fixing clamp is movably disposed on the first insulating rod and is used to provide a second fixing support surface for clamping the drain wire;

[0020] The second movable clamp is movably connected to the second fixed clamp and is movable relative to the second fixed clamp to cooperate with the second fixed clamp to clamp the drainage line.

[0021] Optionally, the second fixing clamp includes:

[0022] The second fixed seat is located on the side of the second fixed support surface away from the first clamping assembly. The second fixed seat is disposed opposite to the second fixed support surface, and a second path for the second movable clamping body to move is formed between the second fixed seat and the second fixed support surface. The second fixed seat has a second threaded hole for threaded connection with the second screw. One end of the second screw passes through the second threaded hole, and the other end is rotatably connected to the second movable clamping body. The second screw is used to drive the second movable clamping body to move relative to the second fixed support surface along the second path by rotation, so as to adjust the clamping distance between the second fixed support surface and the second movable clamping body.

[0023] Optionally, the second insulating rod has a hollow structure, and the second screw includes a second proximal end rotatably connected to the second movable clamp and a second distal end away from the second movable clamp; the second distal end extends along the axial direction of the second screw in a direction away from the second movable clamp and extends through the hollow structure through the second insulating rod to form an operating end for the operator to rotate and operate.

[0024] Optionally, the anti-interference circuit operating lever further includes:

[0025] A handle, which is fixedly connected to the operating end and threadedly connected to the second insulating rod.

[0026] By employing the above technical solution, this application has at least the following beneficial effects:

[0027] The anti-interference circuit operating lever provided in the embodiments of this application has a first insulating rod and a second insulating rod, both made of insulating material. This effectively isolates the operator from direct contact with live wires and drain wires, preventing electric shock risks and meeting the insulation safety requirements for live-line work. The first clamp and the second clamp are isolated from the operator's hands by the first insulating rod and the second insulating rod, respectively, avoiding safety accidents caused by accidental contact with live parts during operation. The fixed first clamp stably holds the live wire, providing a reference point for subsequent drain wire separation. The second clamp is adjusted in position by pushing and pulling the second insulating rod, facilitating precise alignment with the drain wire and quick locking, simplifying the drain wire separation process. The process involves first and second clamps fixing the live conductor and drain wire respectively. Their relative movement allows for direct mechanical separation of the live conductor and drain wire, avoiding the tedious steps of disassembly or manual stripping required in traditional operations and shortening operation time. The first clamp is fixed to the first insulating rod, and the second clamp transmits thrust through the second insulating rod, forming a stable mechanical structure that ensures uniform clamping force during separation, preventing damage to the live conductor and drain wire due to uneven force. The relative movement of the first and second clamps prevents cross-contamination, precisely controlling the contact state between the drain wire and the live conductor, preventing accidental overlap or arcing during separation, and improving operational reliability.

[0036] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0037] See also Figures 1 to 3As shown, according to an embodiment of this application, an anti-interference circuit operating lever is provided, including a first clamping assembly 1 and a second clamping assembly 2; the first clamping assembly 1 includes a first insulating rod 11 and a first clamp 12, the first clamp 12 being fixedly disposed on the first insulating rod 11 for locking live wires; the second clamping assembly 2 includes a second insulating rod 21 and a second clamp 22, the second clamp 22 being movably disposed on the first insulating rod 11 for locking drain wires, the second insulating rod 21 being connected to the second clamp 22 for pushing and pulling the second clamp 22 to bring the second clamp 22 closer to or away from the first clamp 12.

[0038] The anti-interference circuit operating rod provided in this embodiment, the first insulating rod 11 and the second insulating rod 21 are both made of insulating material, which can effectively isolate the operator from direct contact with live wires and drain wires, prevent the risk of electric shock, and meet the insulation safety requirements for live work.

[0039] In this embodiment, the anti-interference circuit operating lever has a first clamp 12 and a second clamp 22 that are isolated from the operator's hand by a first insulating rod 11 and a second insulating rod 21, respectively, to avoid safety accidents caused by accidental contact with live parts during operation.

[0040] The anti-interference circuit operating lever provided in this embodiment can stably clamp the live wire through the fixed first clamp 12, providing a reference point for subsequent separation of the drain wire.

[0041] The anti-interference circuit operating lever provided in this embodiment allows the second clamp 22 to be adjusted in position by pushing and pulling the second insulating rod 21, which facilitates precise alignment of the drain line and quick locking, simplifying the drain line separation process.

[0042] The anti-interference circuit operating lever provided in this embodiment, after the first clamp 12 and the second clamp 22 fix the live wire and the drain wire respectively, can directly achieve mechanical separation of the live wire and the drain wire through relative movement, avoiding the tedious steps of disassembling or manually peeling off section by section in traditional operations, and shortening the operation time.

[0043] The anti-interference circuit operating lever provided in this embodiment has a first clamp 12 fixed to a first insulating rod 11, and a second clamp 22 transmitting thrust through a second insulating rod 21, which can form a stable mechanical structure to ensure uniform clamping force during separation and avoid damage to the live wires and drain wires due to uneven force.

[0044] The anti-interference circuit operating lever provided in this embodiment can achieve the anti-interference effect through the relative movement of the first clamp 12 and the second clamp 22, that is, to precisely control the contact state between the drain wire and the live wire, prevent accidental overlap or arcing during the separation process, and improve the reliability of operation.

[0045] The first insulating rod 11 serves as a basic support structure, providing a fixed fulcrum for the first clamp 12 and transmitting the operating force of the operator.

[0046] Specifically, the first insulating rod 11 can be made of insulating materials such as epoxy resin or glass fiber, which has high insulation strength and can isolate workers from direct contact with live parts to prevent electric shock.

[0047] The first clamp 12 is used to directly lock the live wire, forming a stable clamping reference point to ensure that the live wire remains fixed during the separation process and avoid operational errors or safety risks caused by shaking.

[0048] Specifically, the first clamp 12 is fixedly installed at the front end of the first insulating rod 11, that is, at the end close to the live wire, and its position cannot be moved.

[0049] The second insulating rod 21 is connected to the second clamp 22 and serves as an operating handle for the operator to push and pull to control the movement of the second clamp 22 through mechanical transmission.

[0050] Specifically, the second insulating rod 21 can also be made of insulating materials such as epoxy resin or glass fiber, and together with the first insulating rod 11, it forms a double insulation protection.

[0051] The second clamp 22 is movably mounted on the first insulating rod 11 and is used to lock the drain wire.

[0052] Specifically, the second clamp 22 is slidably engaged with the first insulating rod 11, and the second clamp 22 is sleeved on the outside of the first insulating rod 11 and connected to the second insulating rod 21. Through the pushing and pulling action of the second insulating rod 21, the second clamp 22 moves along the axial direction of the first insulating rod 11, realizing the movement towards or away from the first clamp 12.

[0053] Understandably, in practical applications, initially, the first clamp 12 holds the live wire, while the second clamp 22 is not in contact with the drain wire. During the clamping phase, the operator pushes the second clamp 22 closer to the first clamp 12 using the second insulating rod 21 until it is aligned and the drain wire is locked. During the separation phase, the operator applies a pulling force to the second clamp 22 using the second insulating rod 21, causing the second clamp 22 to move away from the first clamp 12 along the first insulating rod 11, mechanically separating the drain wire from the live wire. During separation, the operator keeps the live wire fixed using the first clamp 12 and controls the movement trajectory of the drain wire using the second clamp 22 to ensure a smooth separation.

[0054] Furthermore, to improve the insulation performance of the first clamping assembly 1 and the second clamping assembly 2, a SiO2 nanofiber / polyimide gradient insulation layer can be added to the outer wall of the first insulating rod 11 and the second insulating rod 21. This insulation layer can be 80 μm thick, and its nanofiber network structure blocks the carbonization path of the insulating material and possesses self-healing capabilities against arc damage, effectively improving the insulation reliability and durability of the operating rod during live-line operations.

[0055] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the second insulating rod 21 is arranged parallel to the first insulating rod 11.

[0056] In this embodiment, the second insulating rod 21 is arranged parallel to the first insulating rod 11. This structural design ensures that the force line of the second insulating rod 21 pushing and pulling the second clamp 22 is completely consistent with the axial direction of the first insulating rod 11, effectively avoiding lateral force due to angular deviation. This ensures the uniqueness of the force transmission direction, allowing the second clamp 22 to slide smoothly along the axial direction of the first insulating rod 11, thereby improving the stability of the entire mechanical structure.

[0057] From a spatial perspective, the second insulating rod 21 and the first insulating rod 11 are in the same plane and their axial directions are completely parallel.

[0058] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the anti-interference circuit operating lever also includes a guide sleeve 3, which is slidably engaged with the second insulating rod 21. The guide sleeve 3 is sleeved on the outside of the second insulating rod 21 and fixedly connected to the first insulating rod 11.

[0059] In this embodiment, the guide sleeve 3 provides a rigid guide path for the movement of the second insulating rod 21 through sliding engagement with the second insulating rod 21. This forces the second insulating rod 21 to move only in a straight line along the axial direction of the first insulating rod 11, preventing the second insulating rod 21 from swinging or tilting laterally due to uneven force during the push-pull process. This ensures that the second clamp 22 is always coaxially aligned with the first clamp 12, improving the positional accuracy of the drain line separation operation.

[0060] The guide sleeve 3 can be made of insulating materials such as epoxy resin or polyimide, and is compatible with the materials of the first insulating rod 11 and the second insulating rod 21 to ensure the overall insulation performance of the anti-interference circuit operating rod.

[0061] The guide sleeve 3 can be a hollow sleeve structure, including a fixed part and a sliding part. The fixed part is fixedly connected to the first insulating rod 11 by bolts or other means, and is used to stably install the guide sleeve 3 on the first insulating rod 11 to ensure that its position remains fixed. The sliding part is sleeved on the outside of the second insulating rod 21 and slides in cooperation with the second insulating rod 21. Specifically, a sliding gap is formed between the inner wall of the sliding part and the second insulating rod 21, allowing the second insulating rod 21 to reciprocate along the axial direction of the first insulating rod 11, while restricting the radial displacement of the second insulating rod 21.

[0062] It is understood that the number of guide sleeves 3 is at least one. When two or more guide sleeves 3 are provided, each guide sleeve 3 is arranged opposite to the first insulating rod 11 along the axial direction and is distributed at intervals.

[0063] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the first clamp 12 includes a first fixed clamp 121 and a first movable clamp 122; the first fixed clamp 121 is fixedly connected to the first insulating rod 11 and is used to provide a first fixed support surface 1212 for clamping the live wire; the first movable clamp 122 is movably connected to the first fixed clamp 121 and can move relative to the first fixed clamp 121 to cooperate with the first fixed clamp 121 to clamp the live wire.

[0064] In this embodiment, the first fixed clamp 121 is fixedly connected to the first insulating rod 11, ensuring that the position of the first clamp 12 will not shift due to external force during operation, providing a stable support point for the clamping action. The first movable clamp 122 can move relative to the first fixed clamp 121. By adjusting the distance between the first movable clamp 122 and the first fixed support surface 1212, it can adapt to live wires of different diameters or shapes, enhancing the adaptability of the first clamp 12 to diverse live wires.

[0065] The first fixing clamp 121 can be a semi-open or U-shaped structure, with one side fixedly connected to the first insulating rod 11 and the other side forming the first clamping surface.

[0066] Specifically, a first fixed support surface 1212 is formed in the first clamping surface near the second clamping component 2. The first fixed support surface 1212 can be a curved surface structure adapted to the shape of the live wire.

[0067] The first movable clamp 122 can be connected to the first fixed clamp 121 by a mechanical structure such as a slide rail or a ball screw, allowing the first movable clamp 122 to move relative to the first fixed clamp 121 on the first clamping surface, thereby moving closer to or away from the first fixed support surface 1212, forming an opening and closing structure for locking the live wire.

[0068] Specifically, the side of the first movable clamp 122 facing the first fixed support surface 1212 can also be a curved surface structure adapted to the shape of the live wire, so as to achieve the purpose of uniformly distributing the clamping force and avoid damage to the insulation layer of the live wire or deformation of the metal conductor due to local stress concentration.

[0069] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the first fixed clamp 121 includes a first fixed seat 1211, which is located on the side of the first fixed support surface 1212 away from the second clamping assembly 2. The first fixed seat 1211 and the first fixed support surface 1212 are arranged opposite to each other, and a first path for the first movable clamp 122 to move is formed between the first fixed seat 1211 and the first fixed support surface 1212. A first threaded hole is provided on the first fixed seat 1211 for threaded connection with the first screw 123. One end of the first screw 123 passes through the first threaded hole, and the other end is rotatably connected to the first movable clamp 122. The first screw 123 is used to drive the first movable clamp 122 to move along the first path relative to the first fixed support surface 1212 by rotation, so as to adjust the clamping distance between the first fixed support surface 1212 and the first movable clamp 122.

[0070] In this embodiment, the rotational motion of the first screw 123 can be converted into the linear motion of the first movable clamp 122 by the cooperation of the first screw 123 and the first threaded hole. The distance between the first fixed support surface 1212 and the first movable clamp 122 can be precisely adjusted to ensure that the first fixed support surface 1212 and the first movable clamp 122 are in close contact with the live wire, so as to avoid unstable clamping due to excessive gap or excessive squeezing of the live wire due to excessive gap.

[0071] The first fixed seat 1211 and the first fixed support surface 1212 are located on both sides of the moving path of the first movable clamp 122.

[0072] The first fixed base 1211 can be a block structure or a plate structure, which is fixedly connected to the main body of the first fixed clamp 121 or integrally formed, and serves as the base for the transmission of the first screw 123, providing a rotation support point.

[0073] The first fixed support surface 1212 is used to form the initial clamping reference surface for the live wire. The first fixed support surface 1212 and the first fixed base 1211 together define a first path, that is, the range of movement trajectory of the first movable clamp 122. This first path is straight, ensuring that the first movable clamp 122 moves in a direction perpendicular to the axis of the live wire, avoiding skewness.

[0074] The distance between the first fixed seat 1211 and the first fixed support surface 1212 is the maximum travel distance of the first movable clamp 122.

[0075] The first fixed base 1211 has a first threaded hole, and the first screw 123 passes through the first threaded hole to form a first threaded pair. The first threaded pair can be a conventional thread structure or a ball screw structure, and the axial movement of the first movable clamp 122 is achieved by rotating the first screw 123.

[0076] The first screw 123 and the first movable clamp 122 are connected by a first rotating joint. The first rotating joint can be a structure of locking pin combined with thrust bearing, which allows the first movable clamp 122 to translate only along the first path when the first screw 123 rotates, without rotating with the first screw 123.

[0077] Understandably, in the initial state, the first movable clamp 122 is located at the farthest point of the first path, close to the first fixed base 1211. At this time, the clamping distance is at its maximum, facilitating the placement of the live wire between the first fixed support surface 1212 and the first movable clamp 122. During the clamping process, the live wire is aligned along the curvature of the first fixed support surface 1212 to ensure it is centered and in close contact with the first fixed support surface 1212. Then, the operator rotates the first screw 123, driving the first movable clamp 122 to move along the first path towards the first fixed support surface 1212. When the resistance to rotating the first screw 123 increases significantly, it indicates that the first movable clamp 122 has contacted the live wire and begun to apply clamping force.

[0078] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the anti-interference circuit operating lever also includes a rotating ring 4. The first screw 123 includes a first proximal end rotatably connected to the first movable clamp 122 and a first distal end away from the first movable clamp 122. The first distal end extends along the axial direction of the first screw 123 in a direction away from the first movable clamp 122, and the rotating ring 4 is fixedly connected to the first distal end.

[0079] In this embodiment, by setting the rotating ring 4, the distance between the point of force application of the operator's hand and the axis of the first screw 123 can be increased, so that the operator can drive the screw to rotate with less force.

[0080] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 3As shown, the second clamp 22 includes a second fixed clamp 221 and a second movable clamp 222; the second fixed clamp 221 is movably disposed on the first insulating rod 11 and is used to provide a second fixed support surface 2212 for clamping the drain wire; the second movable clamp 222 is movably connected to the second fixed clamp 221 and can move relative to the second fixed clamp 221 to cooperate with the second fixed clamp 221 to clamp the drain wire.

[0081] In this embodiment, the second fixed clamp 221 is movably disposed on the first insulating rod 11, allowing the position of the second fixed clamp 221 to be adjusted along the axial direction of the first insulating rod 11. The second movable clamp 222 is movable relative to the second fixed clamp 221. By adjusting the distance between the second movable clamp 222 and the second fixed support surface 2212, it can accommodate drainage lines of different diameters or shapes, enhancing the adaptability of the second clamp 22 to diverse drainage lines.

[0082] The second fixing clamp 221 can also be a semi-open or U-shaped structure, with one side slidingly engaged with the first insulating rod 11 and the other side forming a second clamping surface.

[0083] Specifically, a second fixed support surface 2212 is formed in the second clamping surface near the position of the first clamping component 1. The second fixed support surface 2212 can be a curved surface structure adapted to the shape of the drain line.

[0084] The second movable clamp 222 can be connected to the second fixed clamp 221 through a mechanical structure such as a slide rail or a ball screw, allowing the second movable clamp 222 to move relative to the second fixed clamp 221 on the second clamping surface, thereby moving closer to or away from the second fixed support surface 2212 to form an opening and closing structure for locking the drainage line.

[0085] Specifically, the side of the second movable clamp 222 facing the second fixed support surface 2212 can also be a curved surface structure adapted to the drain line, so as to achieve the purpose of uniformly distributing the clamping force and avoid damage to the insulation layer of the drain line or deformation of the metal conductor due to local stress concentration.

[0086] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 3As shown, the second fixed clamp 221 includes a second fixed seat 2211, which is located on the side of the second fixed support surface 2212 away from the first clamping assembly 1. The second fixed seat 2211 and the second fixed support surface 2212 are arranged opposite to each other, and a second path for the second movable clamp 222 to move is formed between the second fixed seat 2211 and the second fixed support surface 2212. A second threaded hole is provided on the second fixed seat 2211 for threaded connection with the second screw 223. One end of the second screw 223 passes through the second threaded hole, and the other end is rotatably connected to the second movable clamp 222. The second screw 223 is used to drive the second movable clamp 222 to move along the second path relative to the second fixed support surface 2212 by rotation, so as to adjust the clamping distance between the second fixed support surface 2212 and the second movable clamp 222.

[0087] In this embodiment, the rotational motion of the second screw 223 can be converted into the linear motion of the second movable clamp 222 by the cooperation of the second screw 223 and the second threaded hole. This allows for precise adjustment of the distance between the second fixed support surface 2212 and the second movable clamp 222, ensuring that the second fixed support surface 2212 and the second movable clamp 222 are in close contact with the drain line. This avoids unstable clamping due to excessive gaps or excessive squeezing of the drain line due to excessively small gaps.

[0088] The second fixed seat 2211 and the second fixed support surface 2212 are located on both sides of the moving path of the second movable clamp 222.

[0089] The second fixing seat 2211 can be a block structure or a plate structure, which is fixedly connected to the main body of the second fixing clamp 221 or integrally formed, and serves as the base for the transmission of the second screw 223, providing a rotation support point.

[0090] The second fixed support surface 2212 is used to form the initial clamping reference surface for the drainage line. The second fixed support surface 2212 and the second fixed base 2211 together define the second path, that is, the range of movement trajectory of the second movable clamp 222. This second path is straight, ensuring that the second movable clamp 222 moves in a direction perpendicular to the axis of the drainage line, avoiding deflection.

[0091] The distance between the second fixed seat 2211 and the second fixed support surface 2212 is the maximum travel distance of the second movable clamp 222.

[0092] The second fixed base 2211 has a second threaded hole, through which the second screw 223 passes, forming a second threaded pair. The second threaded pair can be a conventional thread structure or a ball screw structure, and the axial movement of the second movable clamp 222 is achieved by rotating the second screw 223.

[0093] The second screw 223 is connected to the second movable clamp 222 via a second rotating joint. The second rotating joint can be a structure combining a locking pin and a thrust bearing, allowing the second movable clamp 222 to translate only along a second path when the second screw 223 rotates, without rotating with the second screw 223.

[0094] Understandably, in the initial state, the second movable clamp 222 is located at the farthest point of the second path, close to the second fixed seat 2211. At this time, the clamping distance is at its maximum, facilitating the placement of the drain line between the second fixed support surface 2212 and the second movable clamp 222. During the clamping process, the drain line is aligned along the curvature of the second fixed support surface 2212 to ensure it is centered and in close contact with the second fixed support surface 2212. Then, the operator rotates the second screw 223, driving the second movable clamp 222 to move along the second path towards the second fixed support surface 2212. When the resistance to rotating the second screw 223 increases significantly, it indicates that the second movable clamp 222 has contacted the drain line and begun to apply clamping force.

[0095] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the second insulating rod 21 has a hollow structure, and the second screw 223 includes a second proximal end that is rotatably connected to the second movable clamp 222 and a second distal end that is away from the second movable clamp 222; the second distal end extends along the axial direction of the second screw 223 in a direction away from the second movable clamp 222, and extends through the hollow structure through the second insulating rod 21 to form an operating end for the operator to rotate and operate.

[0096] In this embodiment, the operating end of the second screw 223 is extended to the outside of the second insulating rod 21, allowing the operator to directly rotate the second screw 223 at a position away from the drain line on the second insulating rod 21. This meets the safety distance requirements for live work and prevents the operator's hands from getting close to the live area.

[0097] The second insulating rod 21 has a hollow interior, forming an axial channel that runs through both ends of the rod. The diameter of this axial channel is slightly larger than the outer diameter of the second screw 223, ensuring that the second screw 223 can pass through and rotate freely.

[0098] When the second screw 223 passes through the axial channel of the hollow structure, the outer wall of the second screw 223 has no contact with the inner wall of the second insulating rod 21 or only a very small gap, which can avoid friction affecting the smoothness of rotation and maintain the integrity of the second insulating rod 21.

[0099] The operating end of the second screw 223 extends completely out of the second insulating rod 21, so the operator does not need to contact the inside of the second insulating rod 21 and can directly apply force to rotate the second screw 223 from the outside of the second insulating rod 21.

[0100] Understandably, during the clamping phase, the live wire is fixed by rotating the first screw 123, and then the operating end of the exposed second screw 223 is rotated to quickly clamp the drain wire. During the separation phase, the second insulating rod 21 is gripped and pulled backward, causing the second clamp 22 and the drain wire to move away from the first clamp 12 along the axial direction of the first insulating rod 11, achieving mechanical separation. The entire process does not require manual contact with the wire, making it safe and efficient.

[0101] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the anti-interference circuit operating lever also includes a handle 5, which is fixedly connected to the operating end and threadedly connected to the second insulating rod 21.

[0102] In this embodiment, the handle 5 has the dual functions of rotating and driving the second screw 223 and pushing and pulling the second chuck 22, eliminating the need for additional tools and simplifying the operation process.

[0103] The handle 5 can be directly connected to the operating end of the second screw 223 through keyway mating, pin fixing or integral molding, etc., to ensure that when the handle 5 rotates, the torque can be 100% transmitted to the second screw 223, driving the second screw 223 to rotate synchronously.

[0104] The handle 5 is threadedly connected to the second insulating rod 21, so that the handle 5 moves along the axial direction of the second insulating rod 21 when rotating, while maintaining the connection between the two.

[0105] Understandably, the operator can quickly adjust the distance between the second movable clamp 222 and the second fixed support surface 2212 by rotating the handle 5 with one hand, while holding the first insulating rod 11 stably with the other hand; when the drain line needs to be separated, the operator can hold the first insulating rod 11 stably with one hand and push and pull the handle 5 with the other hand to realize the axial movement of the first clamp 12, and the whole process does not require contact with the live area.

[0106] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

The above are merely preferred embodiments of this application.
