[0002] Earthing wires are essential protective measures during power industry maintenance and other power operations. Earthing clamps play a crucial role in ensuring the safe operation of the power system and personnel safety. Existing earthing clamps are usually used in conjunction with insulating rods. The earthing clamp includes a lead screw and a clamping plate. By rotating the insulating rod to drive the lead screw to rotate, the clamping plate moves along the extension direction of the lead screw, and finally forces the clamping plate to press the wire tightly, completing the connection between the earthing clamp and the wire, enabling the operator to perform operations safely after earthing protection; however, after the earthing clamp is tightened, the rotation of the lead screw is not restricted, and the earthing clamp is prone to loosening.

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] In order to illustrate the technical solution of the present utility model, it will be described below through specific embodiments.

[0030] As Figures 1-4 shown, an embodiment of the present utility model provides a grounding wire clamp 1 device, including a grounding wire clamp 1 and a driving mechanism. The grounding wire clamp 1 includes a substrate 101, a first clamping member 102 and a second clamping member 103. The first clamping member 102 is fixedly arranged on the substrate 101, and the second clamping member 103 is displaceably arranged on the substrate 101.

[0031] Specifically, as Figure 3 shown, the first clamping member 102 is fixed on the substrate 101, and the second clamping member 103 can move towards the direction close to the first clamping member 102 or away from the first clamping member 102, so that the distance between the first clamping member 102 and the second clamping member 103 is different, so that different diameters of wires can be clamped between the first clamping member 102 and the second clamping member 103 according to actual needs.

[0032] As Figure 3 shown, the first clamping member 102 and the second clamping member 103 are cuboids. It can be understood that the first clamping member 102 and the second clamping member 103 can also be other structures, such as a triangular prism, a structure combined by a cuboid and a cone. The cross-sectional shapes of the first clamping member 102 and the second clamping member 103 can be polygons, or can also be a figure combined by arcs and straight lines.

[0033] The driving mechanism includes a clamping driving assembly 2, a locking assembly 3 and a locking driving assembly 4. The clamping driving assembly 2 includes a rotating member 21 and a lead screw 22. The lead screw 22 is connected to the second clamping member 103, and the rotating member 21 is connected to the lead screw 22. The rotating member 21 is used to drive the lead screw 22 to move, so as to drive the second clamping member 103 to approach or move away from the first clamping member 102.

[0034] The locking driving assembly 4 is connected to the locking assembly 3 and is used to drive the locking assembly 3 to be clamped with the rotating member 21, so as to limit the rotation of the rotating member 21.

[0035] Specifically, after a wire is placed between the first clamping member 102 and the second clamping member 103, the locking assembly 3 is clamped with the rotating member 21, and the locking driving assembly 4 rotates to limit the rotation of the rotating member 21. The lead screw 22 connected to the rotating member 21 moves, pushing the second clamping member 103 to move towards the first clamping member 102. When the wire is clamped, the locking driving assembly 4 and the rotating member 21 no longer rotate, the lead screw 22 and the second clamping member 103 no longer move, and the distance between the first clamping member 102 and the second clamping member 103 no longer changes, realizing the self-locking function of the grounding wire clamp 1 device and preventing the grounding wire clamp 1 from loosening.

[0036] The second clamping member 103 and the lead screw 22 are preferably fixedly connected by bolts.

[0037] In the grounding wire clamp 1 device provided by the present application, a wire is placed between the first clamping member 102 and the second clamping member 103. The locking assembly 3 is clamped with the rotating member 21, and the locking driving assembly 4 drives the rotating member 21 to rotate. The rotating member 21 is connected to the lead screw 22. When the rotating member 21 rotates, the lead screw 22 can be moved. The movement of the lead screw 22 can make the second clamping member 103 move towards the first clamping member 102 to realize the function of clamping the wire. The locking driving assembly 4 no longer drives the rotating member 21 to rotate, and the lead screw 22 no longer moves, so that the distance between the first clamping member 102 and the second clamping member 103 no longer changes, realizing the self-locking function of the grounding wire clamp 1 device and preventing the grounding wire clamp 1 from loosening.

[0038] In an embodiment, the rotating member 21 includes a first ratchet wheel 211, a second ratchet wheel 212 and a nut. The nut is threadedly connected to the lead screw 22, and both the first ratchet wheel 211 and the second ratchet wheel 212 are fixedly arranged on the nut.

[0039] Specifically, the locking drive assembly 4 can drive the first ratchet wheel 211 or the second ratchet wheel 212 to rotate. The first ratchet wheel 211 and the second ratchet wheel 212 are fixedly arranged on the nut. The nut is in threaded connection with the lead screw 22. When the nut rotates, it drives the lead screw 22 to move. The second clamping member 103 connected to the lead screw 22 moves in a direction close to or away from the first clamping member 102, thereby changing the distance between the first clamping member 102 and the second clamping member 103, and realizing clamping or loosening of the wire between the first clamping member 102 and the second clamping member 103.

[0040] In an embodiment, the locking assembly 3 includes a first locking tongue member 31 and a second locking tongue member 32. When the locking drive assembly 4 drives the first locking tongue member 31 to be engaged with the first ratchet wheel 211, the locking drive assembly 4 rotates with the lead screw 22 as the rotation axis to drive the first ratchet wheel 211 to rotate. The first ratchet wheel 211 rotates to drive the lead screw 22 to drive the second clamping member 103 to move in a direction close to the first clamping member 102.

[0041] When the locking drive assembly 4 drives the second locking tongue member 32 to be engaged with the second ratchet wheel 212, the locking drive assembly 4 rotates with the lead screw 22 as the rotation axis to drive the second ratchet wheel 212 to rotate. The second ratchet wheel 212 rotates to drive the lead screw 22 to drive the second clamping member 103 to move in a direction away from the first clamping member 102.

[0042] Specifically, as Figure 4 shown, the first ratchet wheel 211 and the second ratchet wheel 212 have a structure with a round outer and a square inner. The first locking tongue member 31 is engaged with the ratchet teeth on the first ratchet wheel 211, and the second locking tongue member 32 is engaged with the ratchet teeth on the second ratchet wheel 212. The inside of the first ratchet wheel 211 and the second ratchet wheel 212 is a square hole, into which a square nut is sleeved. The thread of the square nut is in threaded cooperation with the lead screw 22. It can be understood that the cross-section of the nut can also be a structure of other polygons, such as a pentagon, a hexagon, etc.

[0043] When it is necessary to clamp the wire between the first clamping member 102 and the second clamping member 103, the first ratchet wheel 211 needs to rotate. At this time, the second ratchet wheel 212 and the second locking tongue member 32 are separated, and the first ratchet wheel 211 and the first locking tongue member 31 are engaged. The locking drive assembly 4 drives the first ratchet wheel 211 to rotate with the lead screw 22 as the rotation axis. The nut connected to the first ratchet wheel 211 rotates, and the lead screw 22 connected to the nut moves, driving the second clamping member 103 to move towards the first clamping member 102. Similarly, when it is necessary to increase the distance between the first clamping member 102 and the second clamping member 103 and take out the wire, the second ratchet wheel 212 needs to rotate. At this time, the first ratchet wheel 211 and the first locking tongue member 31 are separated, and the second ratchet wheel 212 and the second locking tongue member 32 are engaged. The locking drive assembly 4 drives the second ratchet wheel 212 to rotate with the lead screw 22 as the rotation axis. The nut connected to the second ratchet wheel 212 rotates, and the lead screw 22 connected to the nut moves, driving the second clamping member 103 to move away from the first clamping member 102.

[0044] In some embodiments, the locking assembly 3 further includes a first baffle 33. Both the first locking tongue member 31 and the second locking tongue member 32 include a wedge block 311, a connecting rod 312, and an elastic member 313. The first ratchet wheel 211 and the second ratchet wheel 212 are respectively engaged with the wedge block 311. One end of the connecting rod 312 is connected to the wedge block 311, and the end of the connecting rod 312 away from the wedge block 311 passes through the first baffle 33 and is connected to the locking drive assembly 4. The elastic member 313 is sleeved on the outer periphery of the connecting rod 312. One end of the elastic member 313 abuts against the wedge block 311, and the end of the elastic member 313 away from the wedge block 311 abuts against the first baffle 33.

[0045] The elastic member 313 is a spring.

[0046] Specifically, such as Figure 4As shown in the figure, a wedge block 311 is provided at one end of the first locking tongue member 31 close to the first ratchet wheel 211 for engaging with the ratchet teeth of the first ratchet wheel 211. A wedge block 311 is provided at one end of the second locking tongue member 32 close to the second ratchet wheel 212 for engaging with the ratchet teeth of the second ratchet wheel 212. One end of the connecting rod 312 is connected to the wedge block 311 by a thread. Preferably, one end of the connecting rod 312 is fixedly connected to the wedge block 311. The end of the connecting rod 312 away from the wedge block 311 passes through the first baffle 33 and is connected to the second magnetic member 442 in the locking drive assembly 4. An elastic member 313 is provided on the outer periphery of the connecting rod 312. When the first ratchet wheel 211 rotates, the elastic member 313 is used to move the wedge block 311 of the first locking tongue member 31 towards the first ratchet wheel 211, so that the wedge block 311 of the first locking tongue member 31 engages with the ratchet teeth of the first ratchet wheel 211, enabling the first ratchet wheel 211 to continue to rotate under the rotation of the insulating rod 41. Similarly, when the second ratchet wheel 212 rotates, the elastic member 313 is used to move the wedge block 311 of the second locking tongue member 32 towards the second ratchet wheel 212, so that the wedge block 311 of the second locking tongue member 32 engages with the ratchet teeth of the second ratchet wheel 212, enabling the second ratchet wheel 212 to continue to rotate under the rotation of the insulating rod 41.

[0047] As Figures 3-4 As shown in the figure, the locking assembly 3 has two locking tongue members, and correspondingly there are two connecting rods 312. The two connecting rods 312 are defined as the first connecting rod 312 and the second connecting rod 312. The second magnetic member A is connected to the end of the first connecting rod 312 away from the first ratchet wheel 211, and the second magnetic member B is connected to the end of the second connecting rod 312 away from the second ratchet wheel 212. When the second magnetic member A and the first magnetic member 441 attract each other by opposite polarity, the wedge block 311 of the first locking tongue member 31 moves away from the first ratchet wheel 211, and the wedge block 311 of the first locking tongue member 31 does not engage with the ratchet teeth on the first ratchet wheel 211, and the spring on the outer periphery of the first connecting rod 312 is compressed. When the insulating rod 41 is rotated, the rotating shaft 42 rotates, and the first magnetic member 441 on the connecting head 43 moves away from the second magnetic member A. Due to the elasticity, the wedge block 311 moves towards the first ratchet wheel 211, realizing the engagement of the wedge block 311 of the first locking tongue member 31 with the ratchet teeth on the first ratchet wheel 211. At this time, the second magnetic member B and the first magnetic member 441 attract each other by opposite polarity, the wedge block 311 of the second locking tongue member 32 moves away from the second ratchet wheel 212, and the wedge block 311 of the second locking tongue member 32 does not engage with the ratchet teeth on the second ratchet wheel 212, and the spring on the outer periphery of the second connecting rod 312 is compressed.

[0048] In some embodiments, the rotating member 21 further includes a spacer 213. The spacer 213 is fixedly arranged on the nut and is located between the first ratchet wheel 211 and the second ratchet wheel 212.

[0049] Specifically, the spacer 213 is disposed between the first ratchet 211 and the second ratchet 212, serving to isolate the first ratchet 211 and the second ratchet 212.

[0050] In one embodiment, the locking drive assembly 4 includes an insulating rod 41, a rotating shaft 42, a connecting head 43, and a magnetic assembly. The rotating shaft 42 is rotatably connected to the locking assembly 3; the connecting head 43 is fixedly connected between the rotating shaft 42 and the insulating rod 41;

[0051] The magnetic assembly includes a first magnetic member 441 and two second magnetic members 442. The first magnetic member 441 and the second magnetic members 442 have opposite magnetic polarities. The two second magnetic members 442 are respectively connected to the first locking tongue member 31 and the second locking tongue member 32. The first magnetic member 441 is disposed at one end of the connecting head 43 facing the locking assembly 3. The insulating rod 41 rotates to drive the first magnetic member 441 to be disposed opposite to one of the second magnetic members 442, so that the first locking tongue member 31 is engaged with the first ratchet 211, or the second locking tongue member 32 is engaged with the second ratchet 212.

[0052] Specifically, the two second magnetic members 442 are defined as a second magnetic member A and a second magnetic member B. The second magnetic member A is disposed at one end of the first locking tongue member 31 away from the first ratchet 211, the second magnetic member B is disposed at one end of the second locking tongue member 32 away from the second ratchet 212, and the first magnetic member 441 is disposed at one end of the connecting head 43 facing the locking assembly 3. When the first magnetic member 441 is disposed on one side of the second magnetic member A and is opposite to the second magnetic member A, the second magnetic member A and the first magnetic member 441 attract each other due to opposite magnetic polarities, and the first locking tongue member 31 moves away from the first ratchet 211, and the first locking tongue member 31 is not engaged with the ratchet teeth of the first ratchet 211. The rotating shaft 42 is rotatably connected to the locking assembly 3, the rotating shaft 42 is fixedly connected to the connecting head 43, and one end of the connecting head 43 away from the rotating shaft 42 is fixedly connected to the insulating rod 41. When the insulating rod 41 is rotated, the connecting head 43 fixedly connected to the insulating rod 41 also rotates accordingly, and the first magnetic member 441 disposed at one end of the connecting head 43 facing the locking assembly 3 also rotates. The first magnetic member 441 moves away from the second magnetic member A, and the first locking tongue member 31 moves towards the first ratchet 211, and the first locking tongue member 31 is engaged with the ratchet teeth of the first ratchet 211. When the first magnetic member 441 rotates to the relative position of the second magnetic member B, at this time, the second magnetic member B and the first magnetic member 441 approach each other due to opposite magnetic polarities, and the second locking tongue member 32 moves away from the second ratchet 212, and the second locking tongue member 32 is not engaged with the ratchet teeth of the second ratchet 212.

[0053] When the insulating rod 41 rotates to a position where neither of the two second magnetic members 442 is opposite to the first magnetic member 441, the suction force between the first magnetic member 441 and the two second magnetic members 442 is small and insufficient to cause the two second magnetic members 442 to move towards the direction of the rotating shaft 42. At this time, the first locking tongue member 31 is engaged with the first ratchet wheel 211, and the second locking tongue member 32 is engaged with the second ratchet wheel 212. If the insulating rod 41 stops rotating, the rotating member 21 stops rotating, the lead screw 22 stops moving, and the distance between the first clamping member 102 and the second clamping member 103 no longer changes, enabling the clamping function of the wire between the first clamping member 102 and the second clamping member 103, and simultaneously realizing the self-locking function of the grounding wire clamp 1.

[0054] In some embodiments, the locking assembly 3 includes a housing 34 and a first bracket 35. The first locking tongue member 31 and the second locking tongue member 32 are disposed inside the housing 34. The housing 34 is connected to the first bracket 35, and the rotating shaft 42 is rotatably connected to the housing 34.

[0055] Specifically, the first baffle 33 is fixedly connected to the housing 34. When the wedge block 311 moves away from the first ratchet wheel 211 or the second ratchet wheel 212, the spring between the first baffle 33 and the wedge block 311 is compressed.

[0056] The housing 34 is fixedly connected to the first bracket 35, which serves to support the housing 34. The fixed connection method includes fixedly connecting the housing 34 and the first bracket 35 by bolts. The rotating shaft 42 is rotatably connected to the housing 34, and the connecting head 43 connected to the rotating shaft 42 can also make the first magnetic member 441 on the connecting head 43 opposite to one of the two second magnetic members 442, so that the first locking tongue member 31 is engaged with the first ratchet wheel 211, or the second locking tongue member 32 is engaged with the second ratchet wheel 212.

[0057] In some embodiments, the locking drive assembly 4 further includes a second bracket 45. The second bracket 45 is fixedly connected to the connecting head 43, and the second bracket 45 abuts against the first bracket 35.

[0058] Specifically, the second bracket 45 is fixedly connected to the connecting head 43, and the first bracket 35 abuts against the second bracket 45. When the insulating rod 41 is rotated, the second bracket 45 fixedly connected to the connecting head 43 also rotates with the insulating rod 41, and the rotation angle is 0 - 360°. As the rotation angle changes, the position of the first magnetic member 441 on the connecting head 43 also changes.

[0059] In some preferred embodiments, the cross-sectional shapes of the first bracket 35 and the second bracket 45 are both U-shaped.

[0060] In one embodiment, a receiving groove 411 is provided at one end of the insulating rod 41 facing the locking assembly 3. The connecting head 43 is disposed in the receiving groove 411. A first connecting hole is provided on the circumferential surface of the receiving groove 411. A second connecting hole is provided at one end of the connecting head 43 away from the locking assembly 3. The connecting head 43 is fixedly connected to the insulating rod 41 by sequentially passing a connecting shaft 46 through the first connecting hole and the second connecting hole.

[0061] Specifically, as Figure 2 shown, a receiving groove 411 is provided at one end of the insulating rod 41 facing the locking assembly 3. The cross-sectional shape of the receiving groove 411 is J-shaped. It can be understood that the receiving groove 411 can also be of other structures. As Figure 2 shown, the structure of the receiving groove 411 is a J-shaped groove, including a first straight section, a second bent section, and a third bent section. The second bent section is disposed between the first straight section and the third bent section; a first connecting hole is provided at one end of the third bent section away from the second bent section.

[0062] A first connecting hole is provided on the circumferential surface of the receiving groove 411, that is, a first connecting hole is provided on the groove walls on opposite sides of the receiving groove 411. A second connecting hole is provided on the connecting head 43. The connecting shaft 46 is used to sequentially pass through a first connecting hole, the second connecting hole, and the other first connecting hole to fixedly connect the connecting head 43 to the insulating rod 41. The connecting shaft 46, the receiving groove 411, the first connecting hole, and the second connecting hole can quickly snap the insulating rod 41 and the connecting head 43, realizing quick installation.

[0063] It can be understood that the connecting shaft 46 can be a limit pin shaft or other types of connecting shafts 46.

[0064] In some embodiments, the guide rail 104 is provided on the substrate 101 and is located on the side of the first clamping member 102 facing the second clamping member 103. A sliding groove is provided on the second clamping member 103. The second clamping member 103 is slidably connected to the guide rail 104 through the sliding groove.

[0065] Specifically, as Figure 3 shown, guide rails 104 are respectively provided on both sides of the substrate 101. A sliding groove is provided on the second clamping member 103. The second clamping member 103 slides on the guide rail 104 through the sliding groove, thereby changing the distance between the first clamping member 102 and the second clamping member 103; at the same time, it also ensures that the surface of the second clamping member 103 facing the first clamping member 102 has the largest contact area with the first clamping member 102, and the second clamping member 103 has the largest contact area with the wire.

[0066] The cross-sectional shape of the slide groove can be concave, V-shaped, etc. Different cross-sectional shapes can be set according to actual needs, and this application does not limit it.

[0067] Figure 3 A guide rail is set on each side of the substrate 101. It can be understood that the present application does not limit the number of guide rails on the substrate 101. One, two or more guide rails can be set according to actual needs. When one guide rail is set, it is preferred that the guide rail is set in the middle of the second clamping member 103, and a slide groove is set in the middle of the second clamping member 103.

[0068] In some embodiments, a limiting pin 105 and a plurality of limiting holes 106 are provided on the substrate 101. The plurality of limiting holes 106 are arranged at intervals along the moving direction of the second clamping member 103. The limiting pin 105 is arranged in the limiting hole 106 and is located between the first clamping member 102 and the second clamping member 103.

[0069] Specifically, Figure 3 As shown, a plurality of limiting holes 106 are arranged on the substrate 101, and the plurality of limiting holes 106 are arranged between the guide rails on both sides. The plurality of limiting holes 106 are arranged at intervals along the moving direction of the second clamping member 103. The limiting holes 106 at different positions have different distances from the first clamping member 102. On the side of the substrate 101 away from the guide rail, the positions of the limiting holes 106 at different positions have different numbers. When it is necessary to clamp wires of different diameters, the corresponding limiting pins 106 can be placed in the corresponding limiting holes 106, and the limiting pins 105 are arranged between the first clamping member 102 and the second clamping member 103.

[0070] For wires of different diameters, such as commonly used wires with diameters of 120, 90, 75, 69, 35, etc., when the first clamping member 102 and the second clamping member 103 are to clamp wires of different diameters, the limiting holes 106 can be inserted into the corresponding limiting holes 106.

[0071] The limit pin is arranged between the first clamping member 102 and the second clamping member 103. When a wire is placed between the first clamping member 102 and the second clamping member 103 and the wire needs to be clamped, the second clamping member 103 moves toward the first clamping member 102. When the second clamping member 103 moves to abut against the limit pin 105, the limit pin 105 limits the movement of the second clamping member 103 toward the first clamping member 102. At this time, it means that the second clamping member 103 and the first clamping member 102 have clamped the wire in place and the twisting operation can no longer be continued, thereby preventing the first clamping member 102 and the second clamping member 103 from clamping the wire core with too much force, causing destructive damage to the wire, and preventing accidents.

[0072] In some embodiments, a ground wire hole and a ground wire bolt are further provided on the substrate 101, and the ground wire bolt is connected to the ground wire hole. The ground wire is connected to the substrate 101 through the ground wire bolt.

[0073] In some embodiments, the ground wire clamp 1 is made of a metal material, and the metal material is required to be conductive.

[0074] In some embodiments, the ground wire clamp 1 further includes two side plates, the two side plates are arranged on both sides of the substrate 101, and the screw rod 22 passes through one of the side plates and is rotatably connected to the side plate.

[0075] In some embodiments, an anti-slip insulating sleeve 412 is provided at one end of the insulating rod 41 away from the connection head 43, and the anti-slip insulating sleeve 412 is sleeved on one end of the insulating rod 41 away from the connection head 43.

[0076] Specifically, the anti-slip insulating sleeve plays an insulating role, protects the risk of electric shock to the operators, and at the same time increases the frictional resistance during operation.

[0077] The working principle of the ground wire clamp 1 device provided by this application is as follows:

[0078] Place the limit pin 105 in the corresponding limit hole 106 according to the diameter of the corresponding wire, where the limit hole 106 is placed between the first clamping member 102 and the second clamping member 103. Align the receiving groove 411 with one end of the connection head 43 away from the rotation shaft 42, pass the connection shaft 46 through the first connection hole, the second connection hole and another first connection hole in sequence, and fixedly connect the connection head 43 and the insulating rod 41.

[0079] First, connect the ground wire to the ground wire clamp 1 through the ground wire bolt. Define the initial state as that the ratchet teeth of the first ratchet wheel 211 are engaged with the wedge block 311 of the first locking tongue member 31, and the ratchet teeth of the second ratchet wheel 212 are not engaged with the wedge block 311 of the second locking tongue member 32. Hold the anti-slip insulating sleeve of the insulating rod 41 and rotate the insulating rod 41 with the screw rod 22 as the rotation axis, driving the first ratchet wheel 211 to rotate. The nut fixedly connected to the first ratchet wheel 211 drives the screw rod 22 to move, driving the second clamping member 103 fixedly connected to the screw rod 22 to move towards the first clamping member 102; when the ratchet teeth of the first ratchet wheel 211 rotate, it will compress the wedge block 311 that restricts the first locking tongue member 31 to retreat away from the first ratchet wheel 211, the spring in the first locking tongue member 31 is compressed, and at the same time the wedge block 311 of the first locking tongue member 31 slides to the next ratchet tooth, and then under the action of the spring force, the wedge block 311 in the first locking tongue member 31 moves towards the first ratchet wheel 211, so that the wedge block 311 in the first locking tongue member 31 engages with the ratchet teeth of the first ratchet wheel 211; according to the same movement process, the first ratchet wheel 211 continues to move until the second clamping member 103 abuts against the limit pin 105, thereby locking the wire.

[0080] If it is necessary to take out the wire between the first clamping member 102 and the second clamping member 103, first, it is necessary to rotate the insulating rod 41 (rotation not around the lead screw 22 as the rotation axis), so that the rotating shaft 42 rotates, and the first magnetic member 441 is rotated to the position of the second magnetic member A, and the first magnetic member 441 is arranged opposite to the second magnetic member A. At this time, the first magnetic member 441 and the second magnetic member A attract each other with opposite polarities, the second magnetic member A approaches the direction of the connector 43, the wedge 311 of the first locking tongue member 31 moves away from the first ratchet wheel 211, and the wedge 311 of the first locking tongue member 31 does not engage with the first ratchet wheel 211; at the same time, under the action of the spring force of the second magnetic member B, the wedge 311 of the second locking tongue member 32 moves eastward in the direction close to the second ratchet wheel 212, so that the wedge 311 of the second locking tongue member 32 engages with the second ratchet wheel 212. Similarly, hold the anti-slip insulating sleeve of the insulating rod 41 and rotate the insulating rod 41 around the lead screw 22 as the rotation axis, drive the second ratchet wheel 212 to rotate, the nut fixedly connected to the second ratchet wheel 212 drives the lead screw 22 to move, and drives the second clamping member 103 fixedly connected to the lead screw 22 to move away from the first clamping member 102; when the teeth of the second ratchet wheel 212 rotate, it will compress and limit the wedge 311 of the second locking tongue member 32 to retract in the direction away from the second ratchet wheel 212, the spring in the second locking tongue member 32 is compressed, and at the same time the wedge 311 of the second locking tongue member 32 slides to the next tooth. Under the action of the spring force, the wedge 311 in the second locking tongue member 32 moves in the direction close to the second ratchet wheel 212, and at the same time the wedge 311 in the second locking tongue member 32 will engage with the teeth of the second ratchet wheel 212. According to the same movement process, the second ratchet wheel 212 continues to move until the second clamping member 103 is far away from the first clamping member 102, and the wire becomes loose, so as to take out the guide wire.

[0081] For the grounding wire clamp 1 device provided in this application, the structures of the grounding wire clamp 1, the locking component 3 and the locking drive component 4 can prevent the wire clamp from exerting excessive torque and pinching the wire. At the same time, the locking component 3 can prevent the grounding wire clamp 1 from loosening, ensure reliable grounding of the tightened grounding wire clamp 1, and greatly reduce the operation risk; a receiving groove 411 is arranged at one end of the insulating rod 41, a first connection hole is arranged on the peripheral surface of the receiving groove 411, a second connection hole is arranged at the end of the connector 43 close to the insulating rod 41, and the connecting shaft 46 passes through the first connection hole and the second connection hole in sequence to quickly connect the insulating rod 41 and the connector 43, and at the same time, the grounding wire clamp 1 and the insulating rod 41 can be separated for operation.
