Description

Technical Field

[0001] The invention relates to the technical field of grounding ring installation, in particular to an electric installation tool for a grounding ring. Background Art

[0002] In the power outage maintenance project, in order to ensure the safety of the operation, it is often necessary to install grounding wires on the overhead lines in advance. However, from the design and construction of medium and low voltage insulated distribution line projects, most of the insulated wires are installed without grounding rings. When the line is under maintenance, the grounding wire hanging operation cannot be carried out, resulting in serious violations of regulations such as lack of places to hang the grounding wire, which threatens the personal safety of maintenance personnel.

[0003] At present, the installation of grounding rings mainly adopts the method of insulating boom truck + gloves. The operator wears insulating gloves to install the grounding ring on the overhead line, and a lot of shielding work needs to be done before installation. This hanging method requires the configuration of a boom truck, which not only increases the construction cost, but also increases the workload of the operator. In addition, the use of insulating boom trucks is limited by terrain conditions. In fields or narrow road areas, the boom truck cannot reach them, so the insulating rod method is required for installation.

[0004] For example, a grounding hanging ring electric installation tool with publication number CN117954932A includes: an installation module; an impact module, the impact module includes an impact electric wrench and a connecting flange, a countersunk hole is arranged on the outer side of the connecting flange, and a nut is arranged on the inner side of the connecting flange; the beneficial effect is: when the remote control sends a command to loosen the wire clamp, the planetary reduction motor drives the cam to rotate to a specified position, at this time, the locking nut on the grounding hanging ring is placed in the hexagonal hole in the fastening gear, the remote control is controlled to send a command to clamp the wire clamp, the planetary reduction motor drives the cam to rotate to a specified position, the movable clamp block of the grounding hanging ring is fixed, the wire clamp installation tool and the fixed wire clamp are sent to the overhead line to be installed through the insulating operating rod, the remote control is controlled to send a command to install the wire clamp, the impact electric wrench rotates, and finally drives the locking gear to rotate, the locking nut presses the movable clamp block, and locks the wire clamp on the overhead line.

[0005] The above-mentioned prior art realizes that the grounding ring is hung on the electric wire, and the nut is screwed by an electric wrench to realize that the grounding ring is fastened to the electric wire. Although the installation of the grounding ring is realized, it does not mean that the installation of the grounding ring is completed after the grounding ring is fastened to the electric wire. The grounding ring and the wire clamp protective cover are not fastened well, and the above-mentioned prior art does not solve the fastening of the wire clamp protective cover. Therefore, the above-mentioned prior art only completes half of the installation progress of the grounding ring.

[0038] The following is combined with Figures 1 to 14 The present invention is described in further detail.

[0039] The present invention uses the existing hanging tools to install the grounding ring on the overhead line, but at this time the wire clamp protection cover of the grounding ring does not have an effective box cover and the box cover is not fastened. The existing hanging tools can adopt existing technology, such as an electric installation tool for grounding ring with publication number CN117954932A, but the present invention is not limited to the existing technology, and other existing tools that can realize the installation of grounding rings are also acceptable.

[0040] Based on the above, after the grounding ring is installed on the overhead line, the wire clamp protective cover is not covered, which means that the grounding ring is not completely installed. Based on this, the present invention installs the wire clamp protective cover and fastens the cover after the grounding ring is installed, thereby realizing the complete electric installation of the grounding ring on the overhead line.

[0041] See also Figure 1 The grounding hanging ring targeted by the present invention is composed of a U-shaped ring 110, a fixed clamp block 120, a movable clamp block 130, a movable nut 140, a wire clamp protective cover 150 and an insulating sleeve 160. The U-shaped ring 110 is arranged at the lower end of the fixed clamp block 120, and the U-shaped ring 110 is sleeved with an insulating sleeve 160, but the insulating sleeve 160 is not arranged at the middle of the horizontal section at the bottom of the U-shaped ring 110, so as to facilitate the subsequent direct contact between the grounding wire and the U-shaped ring 110. The movable clamp block 130 is slidably matched with the fixed clamp block 120 through a fixed screw, and the movable nut 140 is threadedly connected with the fixed screw. The overhead line is arranged between the fixed clamp block 120 and The movable clamp block 130 is connected with the fixed screw through the movable nut 140, so that the overhead line is clamped and fixed by the movable clamp block 130 and the fixed clamp block 120. The wire clamp protective cover 150 hinged on the upper end of the fixed clamp block 120 is flipped downward, and then the wire clamp protective cover 150 is adapted and fastened with the buckle 180 at the bottom of the fixed clamp block 120 away from the hinge. The wire clamp protective cover 150 is clamped and fixed. The fixed clamp block 120, the movable clamp block 130 and the overhead line clamped in the area between the fixed clamp block 120 and the movable clamp block 130 are protected by the wire clamp protective cover 150.

[0042] It should be noted that the buckle 180 can also be arranged on the wire clamp protective cover 150, and the slot 170 is arranged on the fixed clamp block 120. The specific arrangement method depends on the specific model of the grounding hanging ring. The present invention does not limit this. In order to facilitate the explanation of the technical solution of the present invention, the present invention limits the buckle 180 to the fixed clamp block 120, and the slot 170 to the wire clamp protective cover 150.

[0043] Embodiment 1:

[0044] See also Figure 2A grounding hanging ring electric installation tool includes an insulating rod 2 and an insulating rod 4. The insulating rod 2 is provided with a pressing tool 3 for pressing the wire clamp protective cover 150. The insulating rod 2 is provided with a fastening tool 5 for fastening the groove 170 of the wire clamp protective cover 150 with the buckle 180 of the fixed clamp block 120 to achieve fastening and fastening between the wire clamp protective cover 150 and the fixed clamp block 120.

[0045] The insulating rod 1 2 and the insulating rod 2 4 are both detachably connected by multiple short rods to adapt to the required extension length in different situations.

[0046] A connecting component 6 is provided between the insulating rod 1 2 and the insulating rod 2 4 to connect the insulating rod 1 2 and the insulating rod 2 4 to form a whole, so that the staff can operate the capping tool 3 and the fastening tool 5 at the same time.

[0047] See also Figure 3 and Figure 4 Specifically, the pressing tool 3 includes a pressing vertical bar 31, the lower end of the pressing vertical bar 31 is detachably installed with the top of the insulating rod 2 through a plum blossom head, and the upper and lower ends of the pressing vertical bar 31 are provided with connecting rods 32 extending along the left and right directions. The left and right ends of the upper connecting rod 32 can be detachably installed with a pressing strip 1 33 extending forward and backward, and the left and right ends of the lower connecting rod 32 can be detachably installed with a pressing strip 2 34 extending forward and backward, wherein the lower side of the front end of the pressing strip 1 33 is also set as an arc structure, which is convenient for the pressing strip 1 33 to push the wire clamp protective cover 150 to flip downward.

[0048] During the specific implementation, the staff holds the insulating rod 12 to drive the front end of the pressure strip 133 to push the wire clamp protection cover 150, and the front end of the pressure strip 133 is set to an arc structure, which helps the arc structure at the front end of the pressure strip 133 to form a downward pushing force to achieve the smooth downward flipping of the wire clamp protection cover 150. When the pressure strip 133 drives the wire clamp protection cover 150 to flip downward, the pressure strip 2 34 is placed under the overhead line, and the two pressure strips 2 34 pass through the left and right sides of the wire clamp protection cover 150 respectively until a shape is formed. Figure 3 In the state shown, the wire clamp protective cover 150 is flipped over smoothly.

[0049] It should also be noted that when dealing with different models of grounding hanging rings, the lengths of the wire clamp protective cover 150 in the left and right directions are different. In order to avoid the problem that when the pressing tool 3 flips the wire clamp protective cover 150, the distance between the two pressure strips 34 is smaller than the length of the wire clamp protective cover 150 in the left and right directions, resulting in the two pressure strips 34 being unable to pass smoothly from the left and right sides of the wire clamp protective cover 150, thereby affecting the subsequent fastening tool 5 to fasten the wire clamp protective cover 150 on the fixed clamp block 120.

[0050] To this end, the present invention sets the connecting rod 32 at the lower end of the pressure cover vertical bar 31 as a bidirectional elastic telescopic rod that always drives the connecting rod 32 to move toward the middle of the pressure cover vertical bar 31, so that the pressure strips 34 at both ends of the connecting rod 32 can move in the left and right directions, and the front ends of the two pressure strips 34 are provided with arc sections 341 extending in directions away from each other, which are used to adapt to grounding rings of different lengths on the left and right, so that the two pressure strips 34 can smoothly pass through the left and right sides of the wire clamp protective cover 150.

[0051] Furthermore, a push protrusion 311 is provided on the front side of the lower end of the pressure cover vertical bar 31, which is used to drive the slot 170 of the wire clamp protective cover 150 to align with the buckle 180 of the fixed clamp block 120, thereby facilitating the subsequent fastening tool 5 to drive the slot 170 and the buckle 180 to fasten.

[0052] See also Figure 3 and Figure 5 The fastening tool 5 includes a threaded rod 51, the lower end of the threaded rod 51 is detachably mounted on the upper end of the insulating rod 24 through a plum blossom head, a hanging frame 52 is threadedly connected to the threaded rod 51, and two hanging hooks 53 distributed on the left and right are provided on the hanging frame 52. The hanging hooks 53 are hung on the horizontal section at the bottom of the U-shaped ring 110, and a push plate 54 is rotatably provided on the top of the threaded rod 51, which is used to push the wire clamp protective cover 150 to realize the fastening of the card slot 170 to the buckle 180 of the fixed clamp block 120.

[0053] During the specific implementation, first hold the insulating rod 24 to drive the hanging hook 53 to hang on the horizontal section at the bottom of the U-shaped ring 110, and then rotate the insulating rod 24 to drive the threaded rod 51 and the hanging frame 52 to cause threaded movement, that is, drive the push plate 54 at the upper end of the threaded rod 51 to move up. It should be noted that the length of the push plate 54 in the left and right directions is greater than the spacing between the two vertical sections of the U-shaped ring 110. Through the limitation of the U-shaped ring 110, the problem of the push plate 54 being driven to rotate synchronously when the threaded rod 51 rotates is avoided. In this way, when the threaded rod 51 rotates, the push plate 54 can be guaranteed to move in the vertical direction until the push plate 54 pushes the slot 170 of the wire clamp protective cover 150 to be fastened to the buckle 180 of the fixed clamp block 120.

[0054] A top block 55 is provided at the rear end of the push plate 54 for sliding along the left and right directions, so that the top block 55 can accurately push the position of the clamp protective cover 150 slot 170. At the same time, since the slot 170 is provided on the clamp protective cover 150, when the slot 170 and the buckle 180 are fastened, the buckle 180 will pass through the slot 170. In order to avoid the upper surface of the top block 55 restricting the buckle 180 from passing through the slot 170, the top block 55 of the present invention is configured as a shell structure with an open upper end, which can ensure that the buckle 180 is in the hollow area in the middle of the top block 55, so that the buckle 180 and the slot 170 can be fastened smoothly.

[0055] Furthermore, for different models of grounding hanging rings, there may be multiple buckles 180 and slots 170 thereon, that is, one, two, or even three. For this reason, the top block 55 of the present invention is slidably installed on the push plate 54, and two, three, or more can be slidably set on the push plate 54 at the same time.

[0056] In addition, the hanging hook 53 of the present invention is also slidably arranged on the hanging frame 52 along the left and right directions to ensure that when it comes to different types of grounding hanging rings, the hanging hook 53 can be hung on the insulating sleeves 160 on both sides of the bottom of the U-shaped ring 110 to prevent the hanging hook 53 from directly contacting the U-shaped ring 110, and the concave surface of the hanging hook 53 is also provided with an insulating layer 56.

[0057] See also Figure 6 and Figure 7 The connecting component 6 includes two longitudinally distributed connecting frames 61 with a hollow shell structure, a two-way telescopic rod 62 is arranged between the two connecting frames 61, and the two telescopic sections of the two-way telescopic rod 62 are both penetrated by the corresponding connecting frames 61. It should be noted that the telescopic section and the fixed section of the two-way telescopic rod 62 can only rotate circumferentially, and cannot slide axially; a fixing ring 63 is provided at the rear end of the connecting frame 61 and is sleeved on the insulating rod 2, and the fixing ring 63 is fastened to the insulating rod 2 by a locking screw, and a winding disk 64 is rotatably arranged in the connecting frame 61, and the winding disk 64 is sleeved and installed on the telescopic section of the two-way telescopic rod 62.

[0058] An extension rod 65 is slidably provided at the front end of the connecting frame 61, and a sliding ring 66 is provided at the end of the extension rod 65 facing away from the connecting frame 61. The sliding ring 66 is movably sleeved on the insulating rod 24. The insulating rod 24 can slide axially along the sliding ring 66 and can also rotate circumferentially in the sliding ring 66. A connecting plate 67 that slides in the connecting frame 61 is provided at the rear end of the extension rod 65. A fixing plate 68 is provided in the connecting frame 61 and is located between the winding disk 64 and the connecting plate 67. A pushing spring 69 is connected between the connecting plate 67 and the fixing plate 68 to drive the connecting plate 67 to move toward the insulating rod 24. A through hole is provided in the middle of the fixing plate 68, and a wire rope 610 is wound on the winding disk 64. The end of the wire rope 610 facing away from the winding disk 64 passes through the through hole of the fixing plate 68 and is connected to the connecting plate 67.

[0059] In specific implementation, after the wire clamp protective cover 150 is flipped downward by using the pressing tool 3, the staff first rotates the two-way telescopic rod 62 circumferentially to drive the winding disk 64 to rotate synchronously, so that the wire rope 610 wound on the winding disk 64 begins to be released. At the same time, the pushing spring 69 can push the connecting plate 67 to move toward the direction of the insulating rod 2 4, thereby increasing the distance between the insulating rod 1 2 and the insulating rod 2 4, avoiding the problem that the pushing plate 54 and the hanging hook 53 collide with the U-shaped ring 110 when the staff controls the insulating rod 2 4 to move upward, making it impossible for the hanging hook 53 to be smoothly hung on the U-shaped ring 110, thereby affecting the subsequent top block 55 to drive the card slot 170 and the buckle 180 to be fastened.

[0060] When the hanging hook 53 and the pushing plate 54 move up smoothly and the hanging hook 53 is above the horizontal section at the bottom of the U-shaped ring 110, the two-way telescopic rod 62 is rotated in the opposite direction to drive the winding disk 64 to rotate in the opposite direction to wind the wire rope 610 on the winding disk 64, and the wire rope 610 will pull the connecting plate 67 toward the winding disk 64, so that the extension rod 65 pulls the insulating rod 24 toward the insulating rod 12 through the sliding ring 66 until the hanging hook 53 is directly above the horizontal section at the bottom of the U-shaped ring 110. At this time, the insulating rod 24 is pulled down, so that the hanging hook 53 can be just hung on the horizontal section at the bottom of the U-shaped ring 110.

[0061] Next, the staff only needs to rotate the insulating rod 24 to make the threaded rod 51 rotate synchronously, so as to achieve the upward movement of the push plate 54, so that the push block 55 pushes the slot 170, so that the slot 170 and the buckle 180 are fastened.

[0062] In addition, it should be noted that the insulating rod 2 4 and the threaded rod 51 are located on the same axis, ensuring that the insulating rod 2 4 and the threaded rod 51 rotate coaxially.

[0063] When the pressing tool 3 is used to drive the wire clamp protective cover 150 to flip downward, the insulating rod 2 4 is connected to the insulating rod 1 2 through the connecting component 6. However, because the insulating rod 2 4 and the sliding ring 66 are in a movable sleeve relationship, the insulating rod 2 4 will slide downward along the sliding ring 66. In order to ensure that the sliding ring 66 can smoothly support the insulating rod 2 4 and the fastening tool 5, the present invention is provided with a stop ring 611 located above the uppermost sliding ring 66 on the insulating rod 2 4. Through the interference cooperation between the stop ring 611 and the sliding ring 66, the downward movement of the insulating rod 2 4 can be limited to support the insulating rod 2 4 and the fastening tool 5.

[0064] Embodiment 2:

[0065] On the basis of embodiment one, the hanging hook 53 is directly hung on the horizontal section at the bottom of the U-shaped ring 110. When the staff turns the insulating rod 24, there is a problem of looseness between the hanging hook 53 and the U-shaped ring 110, that is, the hanging hook 53 is separated from the U-shaped ring 110, which will affect the top block 55 pushing the fastening between the slot 170 and the buckle 180. Therefore, on the basis of embodiment one, this embodiment is provided with an auxiliary mechanism 7 between the hanging frame 52 and the insulating rod 2, which is used to realize the connection and fixation between the hanging frame 52 and the insulating rod 2.

[0066] For details, see Figure 8 and Fig. 9 The auxiliary mechanism 7 includes a sliding frame 71 fastened to the insulating rod 2 by two annular clamps, the sliding frame 71 is provided with a support frame 72 for longitudinal sliding toward one side of the insulating rod 4, the support frame 72 is provided with an extension rod 73 for sliding through toward one side of the insulating rod 2, the hanging frame 52 is provided with a longitudinally extending extension bar 74 on the side of the insulating rod 2, the extension rod 73 is slidably sleeved on one end of the extension bar 74 toward the insulating rod 2, and the extension rod 73 is fastened to the extension bar 74 by screws.

[0067] By setting up the sliding frame 71, the support frame 72, the extension rod 73 and the extension strip 74, the hanging frame 52 and the insulating rod 2 can be connected to form a whole, which can effectively avoid the problem of the hanging hook 53 detaching from the U-shaped ring 110; and because the hanging frame 52 needs to move longitudinally, the present embodiment arranges the support frame 72 on the sliding frame 71 by longitudinal sliding, which can effectively avoid the problem of interference between the support frame 72 and the sliding frame 71 when the hanging frame 52 moves longitudinally.

[0068] However, after the hanging hook 53 is hung on the U-shaped ring 110, it is necessary to limit the longitudinal sliding of the support frame 72 on the sliding frame 71. Therefore, in this embodiment, a locking assembly 75 is provided on the side of the support frame 72 facing the sliding frame 71 for locking the support frame 72 on the sliding frame 71.

[0069] For details, see Fig. 9As shown, the locking assembly 75 includes a locking block 751, a storage groove is formed on the side of the support frame 72 facing the sliding frame 71, the locking block 751 is slidably arranged in the storage groove, and a locking pad 752 is provided on the side of the locking block 751 facing the sliding frame 71 to increase the friction between the locking block and the sliding frame 71, a circular hole is formed on the side of the storage groove away from the sliding frame 71 and a locking cavity is provided, a locking rod 753 is slidably provided on the side of the locking block 751 away from the locking pad 752 and passes through the circular hole and enters the locking cavity, an auxiliary plate 754 is provided on the side of the locking rod 753 away from the locking block 751 and slides in the locking cavity, and the auxiliary plate 754 and the side of the locking cavity facing the locking block 751 are connected A locking spring 755 is connected, and a cam 756 is provided on the side of the auxiliary plate 754 that is rotatable away from the locking spring 755. The raised end of the cam 756 cooperates with the auxiliary plate 754 to drive the auxiliary plate 754 to move toward the sliding frame 71. A control rod 757 is slidably provided at the rotation center of the cam 756. The control rod 757 cooperates with the cam 756 in a longitudinal sliding manner and controls the rotation of the cam 756. The upper and lower ends of the control rod 757 are slidably penetrated through the support frame 72, and the lower end of the control rod 757 is connected to a coaxial matching shaft 758. The two-way telescopic rod 62 is a hollow shell structure that passes through the upper and lower parts, and the matching shaft 758 slides through the two-way telescopic rod 62.

[0070] When it is necessary to limit the movement of the support frame 72 on the sliding frame 71 through the locking assembly 75, the staff only needs to rotate the matching shaft 758, and then control the rotation of the cam 756 through the control rod 757, so that the raised end of the cam 756 abuts against the auxiliary plate 754, driving the auxiliary plate 754 to move toward the sliding frame 71, and then the locking rod 753 drives the clamping block 751 and the clamping pad 752 to move toward the sliding frame 71 until the clamping pad 752 abuts against the sliding frame 71, thereby realizing that the movement of the support frame 72 on the sliding frame 71 is restricted, and the matching shaft 758 is twisted in the opposite direction, so that the raised end of the cam 756 no longer abuts against the auxiliary plate 754, and then under the action of the locking spring 755, the clamping block 751 and the clamping pad 752 return to the storage groove, and the clamping pad 752 no longer abuts against the sliding frame 71.

[0071] Embodiment three:

[0072] On the basis of Example 1, after the pressure strip 133 realizes the downward flipping of the wire clamp protective cover 150, the wire clamp protective cover 150 is pushed to move by the pushing protrusion 311, so that the slot 170 of the wire clamp protective cover 150 is aligned with the buckle 180 of the fixed clamp block 120, which is convenient for the subsequent fastening of the slot 170 and the buckle 180. However, the staff controls the movement of the pushing protrusion 311 through the insulating rod 2. When the length of the insulating rod 2 increases according to the height of the overhead line, the staff controls the force of the pushing protrusion 311 to increase, resulting in the pushing protrusion 311 cannot easily push the wire clamp protective cover 150 to move. In order to avoid this situation, the present invention optimizes the design of the two pressure strips 133 on the basis of Example 1.

[0073] For details, see Figures 10 to 12 The upper end and front side of the pressure strip 33 are both open hollow shell structures, and the front side of the pressure strip 33 is provided with an auxiliary strip 81 through a rotating shaft 80. When the auxiliary strip 81 is received in the pressure strip 33, the lower side of the front end of the auxiliary strip 81 is set to have the same arc structure as the lower side of the front end of the pressure strip 33, and the auxiliary strip 81 is a hollow shell structure with an open lower end. A rotating shaft 82 rotatably installed through a bracket is provided inside the pressure strip 33, and the rotating shaft 82 is placed in the opening area at the lower end of the auxiliary strip 81, and the transmission is carried out between the front end of the rotating shaft 82 and the rotating shaft 80 through the meshing of bevel gears.

[0074] When the rotating shaft 82 rotates, the rotating shaft 80 is driven to rotate through the meshing of the bevel gear, and then the rotating shaft 80 drives the rear end of the auxiliary bar 81 to flip upward until the rear end of the auxiliary bar 81 rotates to a vertical downward state. At this time, the rotating shaft 82 can continue to be rotated to reduce the distance between the bottom of the auxiliary bar 81 in the vertical state and the push protrusion 311, which helps to promote the alignment between the position of the wire clamp protective cover 150 slot 170 and the fixed clamp block 120 buckle 180. After completion, you only need to drive the rotating shaft 82 in the reverse direction to rotate and reset the auxiliary bar 81.

[0075] Since the auxiliary bar 81 needs to rotate around the rotating shaft 80, in order to prevent the rotating shaft 82 from colliding with the front end of the auxiliary bar 81 and interfering with the rotation of the auxiliary bar 81, a clearance gap 83 is provided at the front end of the auxiliary bar 81 of this embodiment to ensure that the rotating shaft 82 can be exactly placed in the clearance gap 83 when the auxiliary bar 81 rotates.

[0076] An internally hollow middle bar 84 is provided between the rear ends of the two pressure bars 33, and a dual-axis motor (not shown in the figure) is provided in the middle bar 84. Both ends of the dual-axis motor are provided with drive shafts 85 that rotate and pass through the middle bar 84, and both ends of the middle bar 84 are provided with inverted L-shaped plates 86. The pressure bar 33 and the auxiliary bar 81 are provided with a square opening on the side facing the middle bar 84 for the vertical section of the L-shaped plate 86 to pass through. The vertical section of the L-shaped plate 86 is installed in the square opening of the auxiliary bar 81, and the horizontal section of the L-shaped plate 86 is fastened to the top of the auxiliary bar 81 by bolts and nuts. The end of the drive shaft 85 away from the dual-axis motor is passed into the auxiliary bar 81, and is connected to the rear end of the rotating shaft 82 through a bevel gear meshing transmission connection.

[0077] By starting the dual-axis motor, the driving shaft 85 is driven to rotate, and the driving shaft 85 drives the rotating shaft 82 to rotate through the bevel gear meshing, so that the rotation of the auxiliary bar 81 can be controlled, and the rotation of the auxiliary bar 81 will drive the middle bar 84 to rotate, so that the middle bar 84 can resist and push the fixed clamp block 120, ensuring the alignment of the wire clamp protective cover 150 slot 170 and the fixed clamp block 120 buckle 180.

[0078] A rubber cushion 87 is disposed on the top of the middle bar 84 , and the middle bar 84 is in direct contact with the fixing clamp 120 through the cushion 87 .

[0079] See also Fig.13 and Fig.14 A vertical groove is provided at the front end of the pressure cover vertical bar 31, and a push block 90 with a hollow shell structure with a rear end opening is rotated at the bottom of the vertical groove through a rotating shaft. A rotating gear 91 is installed on the rotating shaft, and a rack 92 meshing with the rotating gear 91 is provided in the vertical groove for longitudinal sliding, and an electric push rod 93 with an output end connected to the rack 92 is installed in the vertical groove.

[0080] When the auxiliary bar 81 rotates to a vertical downward position, the electric push rod 93 is started to drive the rack 92 to move, and then the rack 92 drives the rotating shaft to rotate, so as to drive the push block 90 to rotate forward, thereby realizing that the push block 90 pushes the wire clamp protective cover 150 to move, ensuring that the slot 170 and the buckle 180 are aligned and fastened.

[0081] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
