Description

Technical Field

[0001] The invention relates to the technical field of grounding components, and particularly to a multifunctional grounding pin and a using method thereof. Background Art

[0002] Currently, when working on power lines, grounding wires are often used for grounding to ensure the safety of maintenance personnel. The structure of the grounding wire includes: a grounding rod, a multi-strand soft copper core wire, and a grounding pin (or a grounding wire clamp). When in use, the multi-strand soft copper core wire needs to be removed, the grounding pin is driven into the ground as a grounding body, and the clamp on the grounding rod is fixed to the equipment that has been de-energized and confirmed to have no voltage, so that the operator can carry out the operation.

[0003] After the grounding wire is used up, it needs to be stored. There are two ways to store the multi-strand soft copper core wire:

[0004] The first way is to use the grounding rod for winding storage. When storing, only need to wind the multi-strand soft copper core wire around the grounding rod, avoiding the mess of the multi-strand soft copper core wire. With the method of using the grounding rod for winding storage, due to the small diameter of the grounding rod, after the multi-strand soft copper core wire is wound around the grounding rod, the winding and unwinding time of the multi-strand soft copper core wire is long, and it is inconvenient to use. In addition, when storing the grounding rod, it needs to be stored separately from the multi-strand soft copper core wire and the grounding pin. When in use, it needs to be searched and installed, resulting in inconvenient use.

[0005] The second way is to use a grounding wire storage box for storage. When storing, wind the multi-strand soft copper core wire around the fixing bracket inside the grounding wire storage box to complete the storage. With the method of using the grounding wire storage box for storage, due to the large distance between the two brackets on the fixing bracket, although the winding and unwinding time is shorter than that of using the grounding rod for storage, in order to ensure the safety of the multi-strand soft copper core wire, the storage box is made of iron material and is relatively heavy. Each time it is used, the storage box needs to be carried, increasing the burden on the operator.

[0006] In addition, in the existing two ways, during the process of driving the grounding pin into the ground, due to the violent vibration, the position of the grounding wire storage structure will shift, and it is easy to appear the phenomenon of sliding, affecting the normal working process and the user experience is not good; in addition, most of the existing grounding pins have a single function and are only used as a temporary grounding body, while for the multifunctional grounding pin, there is a phenomenon that the spring buckle ages and cannot clamp the grounding rod tightly, resulting in the grounding rod being easily disengaged during transportation, bringing great inconvenience to transportation and use.

[0060] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0061] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0062] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0063] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0064] This embodiment provides a multifunctional grounding pin, which is used in the field of power line operations. As Figure 1 shown, the multifunctional grounding pin includes a grounding body 1, a fixing mechanism 2, a first wire winding bracket 3, and a second wire winding bracket 4. The grounding body 1 is in a needle-shaped structure, and the tail of the grounding body 1 has a tip for inserting into the ground. A connecting plate 11 is welded to the head of the grounding body 1, and two connecting holes are provided on the connecting plate 11 for fixing the terminal lugs of the wire, so that the wire is electrically connected to the grounding body 1. The wire specifically refers to the multi-strand soft copper core wire of the grounding wire.

[0065] A fixing mechanism 2 is sleeved on the head of the grounding body 1. The fixing mechanism 2 is located at the end far from the tip. One side surface of the fixing mechanism 2 is configured to selectively engage with the grounding rod, and the fixing mechanism 2 serves to accommodate the grounding rod. A first wire winding bracket 3 is provided on the other side surface of the fixing mechanism 2 for winding the wire. A second wire winding bracket 4 is sleeved on the grounding body 1. The second wire winding bracket 4 is configured to be slidably engaged with the grounding body 1 and selectively engaged with one end of the grounding body 1 close to the tip and the fixing mechanism 2 respectively. Multiple layers of wires are wound between the first wire winding bracket 3 and the second wire winding bracket 4.

[0066] When storage is needed, after sliding the second wire winding bracket 4 along the grounding body 1 towards the tip and engaging with it, the wires are respectively wound between the first wire winding bracket 3 and the second wire winding bracket 4, and the grounding rod is clamped inside one side surface of the fixing mechanism 2; when release is needed, slide the second wire winding bracket 4 along the grounding body 1 away from the tip and engage it on the fixing mechanism 2, so that the multi-layer wound wires are separated from the first wire winding bracket 3 and the second wire winding bracket 4 respectively, and the grounding rod is disengaged from one side surface of the fixing mechanism 2.

[0067] For the multifunctional grounding pin provided in this embodiment, the first wire winding bracket 3 and the second wire winding bracket 4 are respectively connected to both ends of the grounding body 1 to realize the winding of multi-layer wires, so that the wire winding and unwinding time is short and it is convenient for winding and unwinding; by providing a fixing mechanism 2 at one end of the grounding body 1 away from the tip, the fixing mechanism 2 realizes the position fixation of the grounding rod, which is more convenient to use and improves the operation efficiency; when in use, the wires and the grounding rod can be quickly combined into a whole, which is convenient for the operator to carry, saves working time and reduces the labor intensity. In addition, through the sliding fit of the second wire winding bracket 4 and the grounding body 1, it is convenient to switch between the storage state and the release state. The second wire winding bracket 4 is respectively selectively clamped at one end of the grounding body 1 close to the tip and on the fixing mechanism 2. Compared with the prior art, the fixing effect of the second wire winding bracket 4 is good, avoiding the situation that the second wire winding bracket 4 slides down due to violent vibration, ensuring the smooth progress of the grounding body 1 driving into the ground, reducing external interference factors and having a high user experience.

[0068] Further, as Figure 1-2 shown, the first wire winding bracket 3 includes a first connecting rod and a first extension rod. One end of the first connecting rod is connected to the grounding body 1, and the other end is connected to the first extension rod. The first connecting rod is used for wire winding, and the first extension rod extends away from the tip. When the wires are wound in multiple layers, the first extension rod is used for wire limiting to prevent the wires from detaching from the first extension rod.

[0069] Further, as Figure 1-2 shown, the fixing mechanism 2 includes a base 21 and a locking component 22. The base 21 includes a body and a protruding portion. A protruding portion protrudes from the middle position of the body. The outer shape of the body is similar to a cuboid structure, so that the body and the protruding portion form a T-shaped structure. A through hole is formed in the protruding portion, and the through hole is used for the penetration of the grounding body 1. An interference fit is preferably provided between the grounding body 1 and the through hole, so that the grounding body 1 and the through hole are tightly fitted. Fixing screw holes are respectively provided on both sides of the protruding portion. The axial direction of the fixing screw holes is perpendicular to the axial direction of the through hole, and the fixing screw holes and the through hole are communicated with each other. The fixing bolts pass through the fixing screw holes and abut against the outer wall of the grounding body 1 to fasten the fixing mechanism 2 to the grounding body 1.

[0070] On one side of the body of the base 21 away from the protruding part, a bayonet 211 is provided. The bayonet 211 is used to store the grounding rod. At least part of a locking component 22 is slidably arranged inside the body of the base 21. A clamping groove can be formed between the locking component 22 and the bayonet 211. The clamping groove is specifically a C-shaped structure, and the clamping groove is clamped to the grounding rod to realize the detachable connection between the grounding rod and the clamping groove. On the other side of the base 21, it is connected to the first wire-winding bracket 3, so that the first wire-winding bracket 3 and the clamping groove are respectively located on both sides of the grounding body 1, avoiding the interference between the wire and the grounding rod, which brings great convenience to the storage process.

[0071] It can be understood that the number of the clamping grooves and the locking components 22 in this embodiment is three. Each locking component 22 corresponds to one clamping groove, and each clamping groove is used to fix one grounding rod, so that the fixing mechanism 2 can fix three grounding rods at the same time. The number of grounding rods stored in this embodiment is not limited and can be adjusted according to actual production needs.

[0072] Furthermore, as Figure 3 shown, the locking component 22 includes an unlocking part 221, a swinging block 222 and an elastic part 223. On one side of the body close to the bayonet 211 and near the left side of the bayonet 211, a first groove and a second groove are recessed in the inner wall. The first groove, the second groove and the bayonet 211 communicate with each other, and the depth of the first groove is greater than the depth of the second groove. The first groove is used to accommodate the unlocking part 221, so that the unlocking part 221 is slidably arranged in the base 21. An avoidance groove 2211 is opened on the side of the unlocking part 221 close to the bayonet 211. The second groove is used to accommodate the swinging block 222, and the second groove provides a rotating space for the swinging block 222 to rotate in the base 21. By arranging the swinging block 222 to rotate in the base 21, the swinging block 222 can be switched between the unlocking state and the locking state. In the unlocking state, the swinging block 222 is clamped in the avoidance groove 2211. In the locking state, a clamping groove is formed between the side wall of the swinging block 222 close to the bayonet 211 and the bayonet 211. An elastic part 223 is arranged inside the first groove of the base 21. Two ends of the elastic part 223 respectively abut against the unlocking part 221 and the inner wall of the base 21, and the elastic part 223 plays a role of elastic reset.

[0073] Wherein, the cross section of the swinging block 222 is generally a triangular structure, the inner shape of the avoidance groove 2211 is adapted to the outer contour of one corner of the swinging block 222, and the inner part of the avoidance groove 2211 is preferably an arc structure, which is convenient for the swinging block 222 to be clamped into the avoidance groove 2211 or to be disengaged from the avoidance groove 2211.

[0074] As Figure 3-4As shown in the figure, when unlocking is required, press the unlocking member 221, and push the unlocking member 221 in the direction close to the base 21. The unlocking member 221 gradually compresses the elastic member 223. During this process, the swing block 222 rotates relative to the base 21 in the direction away from the bayonet 211 and gradually slides along the opening edge of the avoidance groove 2211 into the avoidance groove 2211, so that the side wall of the swing block 222 close to the bayonet 211 is separated from the side wall of the grounding rod, and the grounding rod can be taken out from the bayonet 211. Under the self-restoring force of the compressed elastic member 223, the elastic member 223 pushes the unlocking member 221 in the direction away from the base 21, thereby realizing the reset of the unlocking member 221; when locking is required, press the unlocking member 221, and push the unlocking member 221 in the direction close to the base 21. The unlocking member 221 gradually compresses the elastic member 223. During this process, the swing block 222 rotates relative to the base 21 in the direction away from the bayonet 211 and gradually slides along the opening edge of the avoidance groove 2211 into the avoidance groove 2211. Then, place the grounding rod in the accommodation space formed by the bayonet 211 and the side wall of the swing block 222. The size of this accommodation space is larger than the size of the card slot, which is convenient for the grounding rod to be placed. After that, release the unlocking member 221. Under the self-restoring force of the compressed elastic member 223, the elastic member 223 pushes the unlocking member 221 in the direction away from the base 21, so that one side of the swing block 222 abuts against the arc-shaped side wall of the avoidance groove 2211 close to the elastic member 223, and the other side of the swing block 222 abuts against the outer peripheral wall of the grounding rod, thereby realizing the clamping of the swing block 222 to the grounding rod.

[0075] Furthermore, the locking assembly 22 further includes a first connecting member 224. The first connecting member 224 is specifically a first bolt. The first bolt penetrates through the body along the height direction of the base 21. The unlocking member 221 is provided with an oblong hole 2212 corresponding to the first connecting member 224. The length direction of the oblong hole 2212 extends along the width direction of the base 21, that is, the pressing direction of the unlocking member 221. The first connecting member 224 is inserted into the oblong hole 2212. During the pressing process of the unlocking member 221, the oblong hole 2212 can slide relative to the first connecting member 224. With this setting, by setting the first connecting member 224, the connection between the unlocking member 221 and the base 21 is realized, ensuring the connection stability of the unlocking member 221. By providing the oblong hole 2212 on the unlocking member 221, the unlocking member 221 can slide along the pressing direction, providing a moving space for the unlocking member 221.

[0076] Further, the locking component 22 further includes a second connecting member 225. The second connecting member 225 is specifically a second bolt. The second bolt penetrates through the main body along the height direction of the base 21. A rotating hole is provided at the top corner position of the swing block 222 close to the second groove. The second connecting member 225 passes through the rotating hole. The second connecting member 225 acts as a rotating shaft, enabling the swing block 222 to rotate along the second connecting member 225.

[0077] As Figure 2 shown, in order to achieve the storage and detachment of the electric wire, the second wire-winding bracket 4 includes a sliding component 41 and a storage rack 42. The sliding component 41 is sleeved on the grounding body 1 and can be slidably matched with it. A storage rack 42 is provided on the sliding component 41 for winding the electric wire. After the sliding component 41 slides towards the tip of the grounding body 1, the distance between the storage rack 42 and the first wire-winding bracket 3 is increased, so that the electric wire can be wound in multiple layers between the storage rack 42 and the first wire-winding bracket 3. After the sliding component 41 slides away from the tip of the grounding body 1, the distance between the storage rack 42 and the first wire-winding bracket 3 is reduced. At this time, the electric wire is in a relaxed state, enabling the multi-layer electric wire to be taken off from between the storage rack 42 and the first wire-winding bracket 3 at one time, realizing the separation of the electric wire and the multi-functional grounding pin. With the sliding fit between the sliding component 41 and the grounding body 1, it is convenient for the storage and detachment of the electric wire, with a simple structure and convenient operation. Among them, the storage rack 42 and the first wire-winding bracket 3 are located on the same side of the grounding body 1, so that when the electric wire is wound and detached, the interference of the sliding component 41 to it is avoided, providing convenience for the storage and separation of the electric wire.

[0078] At the same time, the sliding component 41 can be selectively clamped to one end of the grounding body 1 close to the tip and the fixing mechanism 2 respectively, so that the sliding component 41 can be well fixed in both the storage state and the release state, avoiding the phenomenon that the sliding component 41 slides down due to the impact of vibration.

[0079] Specifically, the storage rack 42 includes a second connecting rod and a second extension rod. One end of the second connecting rod is connected to the sliding component 41, and the other end is connected to the second extension rod. The second connecting rod is used for winding the electric wire. The second extension rod extends towards the tip direction. When the electric wire is wound in multiple layers, the second extension rod is used for limiting the electric wire to prevent the electric wire from detaching from the second extension rod.

[0080] Further, as Figure 2 and Figure 5As shown, the sliding assembly 41 includes a box body 411, a first unlocking assembly 412 and a second unlocking assembly 413. The box body 411 is a hollow rectangular parallelepiped structure. A through hole for the grounding body 1 to pass through is provided on the box body 411. The box body 411 is connected to the storage rack 42, and the box body 411 plays a role of overall support. The first unlocking assembly 412 is rotatably provided in the middle position of the box body 411, and a first snap-in groove is provided on the side of the grounding body 1 close to the tip. The first unlocking assembly 412 can be selectively snapped into the first snap-in groove. When the sliding assembly 41 slides along the grounding body 1 to a position close to the tip, the first unlocking assembly 412 snaps into the first snap-in groove, thereby ensuring the fixing effect of the sliding assembly 41 in the storage state. The second unlocking assembly 413 is rotatably provided in the upper position of the box body 411. The second unlocking assembly 413 is located above the first unlocking assembly 412. A second snap-in groove 212 (as shown in FIG. 2 ) is provided at the bottom of the base 21 in the fixing mechanism 2. Figure 4 As shown in FIG. 2 , the second unlocking component 413 can be selectively engaged in the second engaging groove 212. When the sliding component 41 slides along the grounding body 1 to a position close to the fixing mechanism 2, the second unlocking component 413 is engaged in the second engaging groove 212, thereby ensuring the fixing effect of the sliding component 41 in the released state.

[0081] Furthermore, an axial hole 4113 is provided in the box body 411 along the axial direction of the grounding body 1. Specifically, the box body 411 includes a bottom shell 4111 and a cover plate 4112. Fixing holes are provided at the four corners of the bottom shell 4111 and the cover plate 4112. Fixing bolts are respectively passed through the fixing holes of the bottom shell 4111 and the fixing holes of the cover plate 4112 to form an integral structure of the bottom shell 4111 and the cover plate 4112. The bottom shell 4111 is provided with an opening on one side close to the storage rack 42. A first axial hole is provided at the center of the bottom shell 4111 along its axial direction. The first axial hole is connected to the opening. A cover plate 4112 is provided at the upper end of the bottom shell 4111. A second axial hole is provided at the center of the cover plate 4112 along its axial direction. The first axial hole and the second axial hole are connected to each other to form an axial hole 4113.

[0082] A limiting groove 4114 is arranged on the top of the cover plate 4112. The limiting groove 4114 is a T-shaped structure. A T-shaped limiting plate 4115 is arranged in the limiting groove 4114. The T-shaped limiting plate 4115 is fixed in the limiting groove 4114 by screws. The axial hole 4113 and the T-shaped limiting plate 4115 form a through hole. The through hole is a D-shaped structure. A concave platform 12 is provided on the side of the grounding body 1 away from the first winding bracket 3. The through hole and the concave platform 12 are slidably matched, so that the box body 411 can only perform directional movement on the concave platform 12 of the grounding body 1, which plays a role of limiting, and prevents the cylindrical grounding body 1 from rotating easily during the working process and affecting the working effect.

[0083] Further, the first unlocking component 412 includes a first rotating shaft 4121, a first buckle 4122 and a first resetting member 4123. First mounting holes are respectively provided on two side walls of the opening. The first rotating shaft 4121 passes through the two first mounting holes respectively. The first buckle 4122 is sleeved on the first rotating shaft 4121. The first buckle 4122 can rotate relative to the first rotating shaft 4121 and is clamped in the first clamping groove. The first resetting member 4123 is specifically a torsion spring. The first resetting member 4123 is sleeved on the first rotating shaft 4121 and is located between the first buckle 4122 and the first rotating shaft 4121. The first resetting member 4123 abuts against the inner wall of the first mounting hole.

[0084] Specifically, the first buckle 4122 includes a first handle, a first rotating portion and a first clamping portion. The first rotating portion is located between the first handle and the first clamping portion and is respectively connected thereto. The first rotating shaft 4121 passes through the first rotating portion. The first handle is the driving end. An operator holds the first handle and rotates the first rotating portion relative to the first rotating shaft 4121, so that the first clamping portion rotates in a direction close to or away from the first clamping groove. When the first handle is pressed down, the first clamping portion is driven by the first rotating portion to rotate away from the first clamping groove, realizing the unlocking between the box body 411 and the grounding body 1; when the first handle is lifted, the first clamping portion is driven by the first rotating portion to rotate towards the first clamping groove, realizing the locking between the box body 411 and the grounding body 1. The structure is simple and easy to implement.

[0085] Further, the second unlocking component 413 includes a second rotating shaft 4131, a second buckle 4132 and a second resetting member 4133. A mounting seat is provided on the top of the box body 411. Specifically, two lugs are convexly provided on the top of the cover plate 4112 to form the mounting seat. Second mounting holes are respectively provided on the two lugs. The second rotating shaft 4131 passes through the two second mounting holes respectively. The second buckle 4132 is sleeved on the second rotating shaft 4131. The second buckle 4132 can rotate relative to the second rotating shaft 4131 and is clamped in the second clamping groove 212. The second resetting member 4133 is specifically a torsion spring. The second resetting member 4133 is sleeved on the second rotating shaft 4131 and is located between the second buckle 4132 and the second rotating shaft 4131. The second resetting member 4133 abuts against the inner wall of the second mounting hole.

[0086] Specifically, the second buckle 4132 includes a second handle, a second rotating portion, and a second engaging portion. The second rotating portion is located between the second handle and the second engaging portion and is respectively connected thereto. The second rotating shaft 4131 passes through the second rotating portion. The second handle is the driving end. An operator holds the second handle and rotates the second rotating portion relative to the second rotating shaft 4131, so that the second engaging portion rotates in a direction close to or away from the second engaging groove 212. When the second handle is pressed down, the second engaging portion is driven by the second rotating portion to rotate away from the second engaging groove 212, realizing the unlocking between the box body 411 and the grounding body 1; when the second handle is lifted, the second engaging portion is driven by the second rotating portion to rotate towards the second engaging groove 212, realizing the locking between the box body 411 and the grounding body 1. The structure is simple and easy to implement.

[0087] The working process of the multifunctional grounding needle provided in this embodiment is as follows:

[0088] When storage is required, the box body 411 is slid along the grounding body 1 towards the tip, and the first buckle 4122 of the first unlocking assembly 412 is engaged in the first engaging groove of the grounding body 1. At this time, the storage rack 42 of the second wire winding bracket 4 is in a fixed state, and the maximum distance exists between the storage rack 42 and the first wire winding bracket 3. The wires are respectively wound between the first wire winding bracket 3 and the second wire winding bracket 4. At the same time, the unlocking member 221 is pressed, and the unlocking member 221 is pushed towards the base 21. The unlocking member 221 gradually compresses the elastic member 223. The swing block 222 rotates away from the bayonet 211 relative to the base 21 and gradually slides along the opening edge of the avoidance groove 2211 into the avoidance groove 2211. Then, the grounding rod is placed in the accommodation space formed by the bayonet 211 and the side wall of the swing block 222 for easy placement of the grounding rod. After that, the unlocking member 221 is released. Under the self-restoring force of the compressed elastic member 223, the elastic member 223 pushes the unlocking member 221 to move away from the base 21, so that one side of the swing block 222 abuts against the arc-shaped side wall of the avoidance groove 2211, and the other side of the swing block 222 abuts against the outer peripheral wall of the grounding rod, thereby realizing the engagement of the swing block 222 with the grounding rod, and thus realizing the storage of the grounding rod by the fixing structure;

[0089] When release is required, the first buckle 4122 of the first unlocking component 412 is disengaged from the first clamping groove of the grounding body 1 to unlock the box body 411. Then the box body 411 is slid along the grounding body 1 in a direction away from the tip, so that the multi-layer wound wires are separated from the first wire winding bracket 3 and the second wire winding bracket 4 respectively. After that, the box body 411 is continuously slid along the grounding body 1 in the direction away from the tip, and the second buckle 4132 of the second unlocking component 413 is clamped into the second clamping groove 212 of the fixing mechanism 2 to fix the second wire winding bracket 4. At the same time, the unlocking member 221 is pressed, and the unlocking member 221 is pushed in a direction close to the base 21. The unlocking member 221 gradually compresses the elastic member 223. The swinging block 222 rotates relative to the base 21 in a direction away from the bayonet 211 and gradually slides along the opening edge of the avoidance groove 2211 into the avoidance groove 2211, so that the side wall of the swinging block 222 close to the bayonet 211 is separated from the side wall of the grounding rod, facilitating the removal of the grounding rod from the bayonet 211.

[0090] This embodiment also provides a method for using a multi-functional grounding pin for operating the above multi-functional grounding pin. The method for using the multi-functional grounding pin includes: when storage is required, after sliding the second wire winding bracket 4 along the grounding body 1 in a direction close to the tip and engaging with it, the wires are respectively wound between the first wire winding bracket 3 and the second wire winding bracket 4, and the grounding rod is clamped into one side surface of the fixing mechanism 2; when release is required, the second wire winding bracket 4 is slid along the grounding body 1 in a direction away from the tip and clamped on the fixing mechanism 2, so that the multi-layer wound wires are separated from the first wire winding bracket 3 and the second wire winding bracket 4 respectively, and the grounding rod is disengaged from one side surface of the fixing mechanism 2.

[0091] For this method of using the multi-functional grounding pin, sliding the second wire winding bracket 4 along the grounding body 1 in a direction close to or away from the tip facilitates the storage and separation of the wires between the first wire winding bracket 3 and the second wire winding bracket 4. Connecting or disconnecting the fixing mechanism 2 to or from the grounding rod facilitates the installation and fixation of the grounding rod, with convenient operation and good user experience.
