Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0016] like Figures 1-4 As shown, this embodiment proposes an insulating operating rod, including a first connecting rod 1, and also includes a fixed sleeve 2, a connecting groove 3, a connecting block 4, a movable sleeve 5, a fixed frame 6, a movable block 7, a plug-in block 8, a tightening spring 9, a plug-in rod 10, and a movable frame 11; like Figure 3 and Figure 4 As shown, the fixed sleeve 2 is fitted onto the outer surface of the first connecting rod 1. A connecting groove 3 is provided inside the first connecting rod 1. A connecting block 4 is slidably connected inside the connecting groove 3. A movable sleeve 5 is installed on the outer side of the connecting block 4. The operator can slide the movable sleeve 5 according to the usage situation, so the operator's hands can change position and adjust posture at will. The fixed frame 6 is installed at the top of the first connecting rod 1. A movable block 7 is slidably connected inside the fixed frame 6. A movable groove is provided inside the fixed frame 6. The movable groove is slidably connected to the movable block 7. A plug-in block 8 is installed on the upper surface of the movable block 7. A tightening spring 9 is installed on the outer side of the plug-in block 8. The outer end of the tightening spring 9 is installed inside the fixed frame 6. A plug-in rod 10 is installed on the inner side of the plug-in block 8. A movable frame 11 is installed on the upper surface of the plug-in block 8.
[0017] like Figure 1 and Figure 2As shown, a connector 12 is inserted inside the fixed frame 6. A connector hole is provided inside the fixed frame 6, the diameter of which matches the diameter of the connector 12. The connector 12 passes through the connector hole. A second connecting rod 13 is mounted on the upper surface of the connector 12. The outer surface of the connector 10 passes through the interior of the second connecting rod 13. A fixing tube 14 is mounted on the outer surface of the second connecting rod 13. An adjusting tube 15 is rotatably connected inside the fixing tube 14. A connecting ring 16 is mounted on the outer surface of the adjusting tube 15. The connecting ring 16 is used to suspend the grounding wire. To protect the operator's first line of defense, the adjusting tube 15 can rotate along the interior of the fixing tube 14 with the pull of the grounding wire, allowing the connecting ring to... 16. During the use of this device, it is always vertically downward to avoid the grounding wire getting tangled on the first connecting rod 1. The upper surface of the second connecting rod 13 is equipped with a threaded post 17, and the outer surface of the threaded post 17 is threaded with a third connecting rod 18. The upper surface of the third connecting rod 18 is equipped with a support seat 19, and the upper surface of the support seat 19 is equipped with an auxiliary frame 20. The auxiliary frame 20 is used for pulling the switch. The first connecting rod 1, the second connecting rod 13, the third connecting rod 18, the support seat 19, and the auxiliary frame 20 are all made of insulating material. The grounding wire and the quick-release plug-in piece 12 are provided to enhance the protective function of the device and reduce the probability of safety accidents.
[0018] In this embodiment, the movable frame 11 is moved outward, causing the plug-in block 8 to move outward. The plug-in block 8 moves outward, causing the movable block 7 to move outward. The movable block 7 moves outward along the fixed frame 6. The plug-in block 8 moves outward, compressing the top spring 9. The plug-in block 8 moves outward, causing the plug-in rod 10 to move outward. The second connecting rod 13 is manipulated to insert the plug-in piece 12 into the fixed frame 6. The movable frame 11 is released, causing the top spring 9 to rebound and drive the plug-in block 8 to move inward. The plug-in block 8 moves inward, causing the plug-in rod 10 to move inward. The plug-in rod 10 moves inward and inserts into the second connecting rod 13. At the same time, the insertion block 8 moves inward, driving the moving block 7 to move inward. After the moving block 7 moves inward along the fixed frame 6, it puts the third connecting rod 18 on the outer surface of the threaded column 17 and tightens the third connecting rod 18 clockwise to complete the assembly. The grounding wire is suspended on the connecting ring 16, so that the adjusting tube 15 rotates along the inside of the fixed tube 14 under the influence of gravity. The connecting ring 16 is rotated to the bottom of the fixed tube 14. The operator holds the fixed sleeve 2 with his left hand and operates the moving sleeve 5 with his right hand to slide along the connecting groove 3 through the connecting block 4. Alternatively, the operator holds the fixed sleeve 2 with his right hand and operates the moving sleeve 5 with his left hand to slide along the connecting groove 3 through the connecting block 4. This is used to adjust the support point of the device for the operator before the switch is pulled. In an emergency, the connecting wire serves as the first line of defense for the operator. The current conducted by the device is directed to the ground, and the movable frame 11 is moved outward, causing the plug block 8 to move outward as well. The plug rod 10 is then pulled out from inside the second connecting rod 13. This serves as the second line of defense for the operator, preventing penetration from a distance. At this time, the second connecting rod 13 is affected by gravity, causing the plug piece 12 to be pulled out from inside the fixed frame 6 and fall to the ground, preventing injury to the operator.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
