Embodiment 2

[0025] Refer to Figures 1-8, and on the basis of the first embodiment, it is further obtained that the clamping mechanism 3 includes a base 31, the base 31 is fixedly connected to the top of the support cylinder 21, semicircular seats 32 are respectively arranged at both ends of the top of the base 31, a rotating shaft 33 is rotatably connected inside the semicircular seat 32, a bar 34 is fixedly connected to one end of the rotating shaft 33, a second spring 341 is fixedly connected to one end of the top of the bar 34, a T-shaped rod 35 is fixedly connected to one end of the second spring 341, a limiting rod 36 is fixedly connected to one end of the bottom of the T-shaped rod 35, an L-shaped strip 37 is fixedly connected to the side of the semicircular seat 32, a positioning semi-ring 38 is fixedly connected to the side of the semicircular seat 32, a clamping block 39 is fixedly connected to the surface of the rotating shaft 33, a gear set 391 is fixedly connected to the right end of the rotating shaft 33, a circular hole is opened inside one end of the L-shaped strip 37, and the surface of the limiting rod 36 is slidably connected to the inside of the circular hole. There are two clamping blocks 39, and the two clamping blocks 39 are symmetrically distributed at both ends of the top of the base 31 respectively.

[0026] Furthermore, a positioning hole is opened in the positioning semi-ring 38, the surface of the T-shaped rod 35 matches the inside of the positioning hole, a perforation is opened at one end of the top of the bar 34, the surface of the T-shaped rod 35 penetrates through the perforation opened at one end of the top of the bar 34, and the rotation of the rotating shaft 33 will drive the gear set 391 to rotate together through the connection with the gear set 391. Under the transmission action of the gear set 391, the clamping block 39 fixed on the surface of the rotating shaft 33 will rotate accordingly, thereby realizing the precise clamping action on the graphite grounding wire. The third embodiment

[0027] Refer to Figures 1-8 , and on the basis of the first embodiment, it is further obtained that the disassembly and assembly mechanism 4 includes a U-shaped seat 41, the U-shaped seat 41 is fixedly connected to the top of the base 31, third springs 42 are respectively fixedly connected to both ends of one side of the U-shaped seat 41, a support bar 43 is fixedly connected to one end of the third spring 42, insertion rods 44 are respectively fixedly connected to both ends of one side of the support bar 43, a long strip 45 is fixedly connected to one end of the insertion rod 44, positioning strips 46 are respectively fixedly connected to both ends of one side of the long strip 45, and a support bottom strip 47 is fixedly connected to the middle of the top of the base 31.

[0028] Furthermore, insertion holes are respectively opened at the front and rear ends of the semicircular seat 32, the surface of the positioning strip 46 matches the inside of the insertion hole, a through hole is opened inside the U-shaped seat 41, and the surface of the insertion rod 44 penetrates through the through hole opened inside the U-shaped seat 41. The movement of the long strip 45 will further drive the positioning strips 46 fixedly connected to both ends of its side to displace. When the positioning strip 46 moves to a certain extent, it will disengage from the pre-set clamping position inside the semicircular seat 32, thereby successfully releasing the limiting effect on the semicircular seat 32.

[0029] In the actual operation process, when this device is in use, during the actual use of this graphite grounding wire connecting fitting, when facing a complex and changeable on-site environment and the need to flexibly adjust the height and angle of the clamping mechanism, it can be achieved through a carefully designed operation process. Specifically, since the top inner part of the support 22 is rotatably connected to the gear rack 23, this lays the foundation for subsequent adjustment operations. At this time, pull down the rotating ring 25. Under the limit constraint of the bottom ring 252, the rotating ring 25 must overcome the strong elastic force of the first spring 251. During this process, the downward movement of the rotating ring 25 will drive the connected support rod 24 to move downward synchronously, and the movement of the support rod 24 will further cause the telescopic rods 231 at both ends to act, thereby driving the gear rack 23 to rotate smoothly; Meanwhile, due to the precise meshing relationship between the gear rack 23 and the rack 26, when the gear rack 23 starts to rotate, its strong driving force will push the rack 26 to slide smoothly within the rectangular hole pre-opened inside the support 22. As the rack 26 slides, the clamping rod 27 fixedly connected to one end thereof will also move together. When the clamping rod 27 moves to a certain position, it will disengage from the pre-set clamping position on the surface of the positioning ring 28, thus successfully releasing the limit restraint on the dial ring 29. After this series of operations are completed, the operator can easily turn the dial ring 29. The rotation of the dial ring 29 will drive the connected support cylinder 21 to rotate together, and then drive the base 31 located at the top of the support cylinder 21 to rotate. In this way, during actual operation, the staff can adjust the angle of the clamping mechanism according to the line direction of the grounding wire to ensure that it can accurately and stably clamp the grounding wire; When it is necessary to clamp the graphite grounding wire, another ingenious operation mechanism is involved. At this time, the operator needs to pull the T-shaped rod 35. During this process, the T-shaped rod 35 must overcome the elastic force exerted by the second spring 341, so that the T-shaped rod 35 disengages from the clamping position inside the positioning semi-ring 38. During this operation process, the limiting rod 36 plays a crucial limiting role inside the L-shaped strip 37, which can ensure the stability and accuracy of the T-shaped rod 35 during the movement. When the T-shaped rod 35 disengages from the clamping position of the positioning semi-ring 38, the limiting effect of the rotating shaft 33 is successfully released. At this time, the operator can conveniently turn the dial bar 34. The rotation of the dial bar 34 will drive the closely connected rotating shaft 33 to rotate, and the rotation of the rotating shaft 33 will drive the gear set 391 to rotate together through the connection with the gear set 391. Under the transmission of the gear set 391, the clamping block 39 fixed on the surface of the rotating shaft 33 will rotate accordingly, thereby realizing the precise clamping action on the graphite grounding wire to ensure that the grounding wire will not loosen or fall off during use; In addition, in actual engineering applications, since ground wires of different specifications may need to be paired with clamp blocks 39 of different sizes to achieve the best clamping effect, when encountering such a situation and needing to replace the clamp block 39 according to the specific size of the ground wire, there is also a convenient operation process. Specifically, the staff needs to pull out the insertion rod 44. The movement of the insertion rod 44 will drive the long strip 45 connected to it to move together, and the movement of the long strip 45 will further drive the positioning strips 46 fixed at both ends of one side of it to displace. When the positioning strips 46 move to a certain extent, they will disengage from the pre-set clamping positions inside the semi-circular seat 32, thus successfully releasing the limiting effect on the semi-circular seat 32. After completing this step, the staff can easily disassemble the semi-circular seat 32, and then realize the replacement operation of clamp blocks 39 of different sizes to meet the diverse requirements for ground wire clamping in different engineering scenarios.
