[0034] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Embodiment 1:

[0036] Referring to Figure 1 , an embodiment provided by the present utility model: a multi-section replaceable insulated lock rod clamp, including a first round tube 1 and a second round tube 15. The segmented splicing of the first round tube 1 and the second round tube 15 is convenient for increasing the length of the body, meeting the needs of different working scenarios, and effectively enhancing the applicability. A protective sleeve 3 is fixedly connected to the outer side of the first round tube 1. The protective sleeve 3 is made of insulating material, and the inside of the first round tube 1 is filled with insulating material. By insulating the handheld position and the inside of the first round tube 1, electric shock can be effectively prevented.

[0037] Referring to Figure 1 - Figure 2 , a movable part 2 is slidably connected to the outer side of the protective sleeve 3. A connecting block 4 is fixedly connected to the top of the movable part 2. A locking connecting rod 5 is rotatably connected to the top of the connecting block 4. One end of the locking connecting rod 5 away from the connecting block 4 is provided with a connecting rod 6. The structure of the locking connecting rod 5 is similar to that of a turnbuckle tensioner and can rotate by itself. When rotating, its two ends can extend outwards or contract inwards, which is prior art and will not be elaborated here. One end of the connecting rod 6 is rotatably connected to a connecting rod 7. A limiting component is arranged inside the movable part 2 to limit the position of the connecting block 4. The movable part 2 can slide on the outer side of the protective sleeve 3. When sliding, the positions of the locking connecting rod 5 and the connecting rod 6 can be changed, thereby pushing the connecting rod 7. After adjusting the position of the movable part 2, the movable part 2 and the protective sleeve 3 are clamped through the limiting component, thereby realizing the locking of the position of the movable part 2.

[0038] Referring to Figure 2The limit assembly includes a card block 10, which rotates on the outside of the movable part 2. A spring piece 11 is fixedly connected to one side of the card block 10, and a rack 12 is fixedly connected to the outside of the protective cover 3. The rack 12 and the card block 10 are meshed with each other. When the position of the movable part 2 needs to be adjusted, the card block 10 is pressed downward to rotate the card block 10. At this time, the end of the card block 10 is disengaged from the rack 12, canceling the meshing state with the rack 12. Then, the position of the movable part 2 can be changed along the protective cover 3. After adjusting to the appropriate position, the card block 10 is released. Under the action of the spring piece 11, the card block 10 can be reset and re-engaged with the rack 12, thereby completing the locking of the relative position of the movable part 2 and the protective cover 3. The spring piece 11 is set inside the movable part 2, and the card block 10 is reset by the spring piece 11. One end of the circular tube 1 is provided with a sleeve 22, which is used to protect the open end of the circular tube 1 to increase the aesthetics while providing physical protection.

[0039] Reference Figure 1 and Figure 3 One end of the circular tube 1 is fixedly connected to a connecting column 13, and one end of the circular tube 2 15 is fixedly connected to a mounting seat 14. The connecting column 13 and the mounting seat 14 can be snapped together to adjust the length of the entire tool to meet the needs of different scenarios. The outer side of the mounting seat 14 is slidably connected to a movable ring 16, and an inner groove 17 is provided inside the movable ring 16. A steel ball 18 is provided in the middle of the mounting seat 14. The steel ball 18 is slidably connected to the middle of the inner groove 17. A notch is provided on the inner side of the movable ring 16 to act on the steel ball 18. When the movable ring 16 moves, the position of the steel ball 18 can be changed through this notch. The inner side of the movable ring 16 is fixedly connected to a spring 19, which is sleeved on the outer side of the mounting seat 14. One end of the connecting column 13 is fixedly connected to a plug 20, and a groove 21 is provided on the outer side of the plug 20. The steel ball 18 is slidably connected to the middle of the groove 21. When it is necessary to connect the round tube 2 15 and the round tube 1 1 to lengthen the overall length of the tool, it is only necessary to pull the movable ring 16 toward the mounting seat 14 to squeeze the spring 19, and then insert the plug 20 from the end of the mounting seat 14. When the groove 21 reaches the position of the steel ball 18, the movable ring 16 is released. At this time, the spring 19 acts to push the movable ring 16 to reset, and squeezes the steel ball 18 through the notch on the outside of the movable ring 16, so that the inside of the steel ball 18 enters the groove 21 position, thereby completing the connection between the round tube 1 1 and the round tube 2 15. Conversely, after pulling the movable ring 16 apart, the round tube 1 1 and the round tube 2 15 can be separated. The operation is very simple. Through this multi-section replaceable design, the length can be flexibly adjusted according to specific operation requirements, so that it has a larger operating range and is suitable for electrical equipment operations at various heights or long distances.

[0040] Reference Figure 4, an operating assembly is installed at the end of the connecting rod 7 and the second round tube 15. The operating assembly includes a first clamp head 8 and a second clamp head 9. The first clamp head 8 is fixedly connected to the open end of the connecting rod 7. When the moving part 2 moves to drive the connecting rod 6 to move, the connecting rod 7 will drive the first clamp head 8 to rotate. The second clamp head 9 is fixedly connected to the end of the second round tube 15 away from the mounting seat 14. The first clamp head 8 and the second clamp head 9 are arranged crosswise and engage with each other. When the first clamp head 8 rotates, an angle will be formed with the second clamp head 9. By changing the size of this angle, opening and closing can be achieved to perform a clamping operation on an object. After the preliminary adjustment is achieved by changing the position of the moving part 2, fine adjustment within a small range can also be performed by rotating the locking connecting rod 5, thereby ensuring the clamping effect on the object. Through the clamp, the effect of firmly grasping wires, cables or other components without directly contacting the energized equipment can be achieved, and the risk of slipping or falling off is avoided, ensuring the safety of the operator.

[0041] Embodiment 2:

[0042] Refer to Figure 5 , different from the above embodiment, this embodiment provides another usage mode of the multi-section replaceable insulating lock rod clamp. The operating assembly includes a first lock rod head 81 and a second lock rod head 91. The first lock rod head 81 is fixedly connected to the open end of the connecting rod 7. When the moving part 2 moves to drive the connecting rod 6 to move, the connecting rod 7 will drive the first lock rod head 81 to rotate. The second lock rod head 91 is fixedly connected to the end of the second round tube 15 away from the mounting seat 14. The first lock rod head 81 and the second lock rod head 91 are arranged crosswise and engage with each other. When the first lock rod head 81 rotates, an angle will be formed in cooperation with the second lock rod head 91. By changing the size of this angle, opening and closing can be achieved to perform a locking operation on an object. After the preliminary adjustment is achieved by changing the position of the moving part 2, fine adjustment within a small range can also be performed by rotating the locking connecting rod 5, thereby ensuring the locking effect on the object.

[0043] Working principle: First, when clamping, press the block 10. The block 10 squeezes the elastic piece 11, and the block 10 is separated from the rack 12. Slide the moving part 2 up and down. The moving part 2 drives the locking connecting rod 5 to move back and forth. The locking connecting rod 5 drives the connecting rod 6 to move. The connecting rod 6 drives the connecting rod 7 to move. The connecting rod 7 drives the clamp or the lock rod to open and close. When it is opened and closed to the appropriate position, release the block 10. Under the reaction force of the elastic piece 11, the block 10 automatically engages with the rack 12 for locking. If the locking is not firm, the locking connecting rod 5 can be tightened manually. Its clamp and lock rod can firmly grasp wires, cables or other components without directly contacting the energized equipment, avoiding the risk of slipping or falling off, and ensuring the safety of the operator.

[0044] Secondly, during assembly, press down the movable ring 16, and the movable ring 16 squeezes the spring 19, causing the steel ball 18 to slide in the inner groove 17. Insert the connecting post 13 into the mounting seat 14, and the plug 20 squeezes the steel ball 18. Subsequently, the steel ball 18 is engaged with the groove 21. Finally, release the movable ring 16, and the movable ring 16 is reset under the reaction force of the spring 19, causing the inner groove 17 to squeeze the steel ball 18, enabling quick and convenient segmented connection. By using this multi-section replaceable design, the length can be flexibly adjusted according to specific operation requirements, giving it a larger operating range and being applicable to electrical equipment operations at various different heights or long distances.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
