[0021] Embodiment:

[0022] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0023] The present utility model provides an insulating rod for live working that can be operated by a single person, including a straight handle insulating operation outer rod 1. A straight handle insulating operation inner rod 2 is rotatably connected inside the straight handle insulating operation outer rod 1. A spring device 202 is installed at the top of the straight handle insulating operation inner rod 2. A limit frame 3 is installed at the top of the spring device 202. A pair of J-shaped wire clips 5 are symmetrically installed on one side of the top of the limit frame 3. On the other side of the top of the limit frame 3, there is a connecting rod 4, and an internal hexagonal sleeve 401 is installed at the top of the connecting rod 4. A limiter 7 is sleeved outside the straight handle insulating operation outer rod 1, and a lead fixing device is installed between one side of the limiter 7 and the J-shaped wire clip 5.

[0024] Among them, a pressing plate 8 is installed on one side of the straight handle insulating operation outer rod 1, and the pressing plate 8 extends above the pair of J-shaped wire clips 5. A pressing plate 8 is arranged on the top of the J-shaped wire clip 5 to cooperate with the lead fixing device to fix the J-shaped wire clip 5. After the lead is inserted, the J-shaped wire clip 5 is fixed by the pressing plate 8 and the lead fixing device.

[0025] Among them, the lead fixing device includes a first connecting rod 701, a second connecting rod 702 and an unlocking rope 703. One end of the first connecting rod 701 is rotatably connected to one side of the stopper 7, the rod body of the second connecting rod 702 is rotatably connected to one side of the pressing plate 8, one ends of the second connecting rod 702 and the first connecting rod 701 are rotatably connected through a rotating pin, and both ends of the unlocking rope 703 are respectively connected to the rotating pin and the stopper 7. Through the lever function, the operator operates the lead fixing device at the bottom of the straight handle insulating operating outer rod 1 to clamp the lead to realize the clamping of the lead.

[0026] Among them, one end of the second connecting rod 702 is fixedly connected with a lead fixing rod 6, and a lead fixing ax 601 is connected to one side of the lead fixing rod 6.

[0027] Among them, the bottom end of the rod body of the straight handle insulating operating inner rod 2 extends to the outside of the straight handle insulating operating outer rod 1 and is fixedly connected with an inner rod rotating handle 201.

[0028] The working principle of this embodiment: First, the operator places the wire clamp in the wire clamp groove of the wire clamp fixing operating rod, places the lead in the J-shaped wire clamp 5, operates the tool to lock the lead, and at the same time fixes the J-shaped wire clamp 5. Lift the straight handle insulating operating outer rod 1, pull the straight handle insulating operating inner rod 2, clamp the upper card slot of the J-shaped wire clamp 5 on the energized main wire, hold up the straight handle insulating operating inner rod 2 upward, so that the wire clamp bolt is sleeved in the upper bolt fastening internal hexagonal sleeve 401 of the connecting rod 4. Subsequently, the operator rotates the straight handle insulating operating inner rod 2 to fasten the lower part of the J-shaped wire clamp 5. Finally, the operator operates the lower handle of the tool to loosen the J-shaped wire clamp 5 and the lead, completing the energized connection operation. Through the integrated structure design composed of the straight handle insulating operating outer rod 1 and the straight handle insulating operating inner rod 2, the inner and outer rods are linked, and the lead can be clamped and fixed through the lead fixing device. At the same time, the J-shaped wire clamp 5 can be fastened through the internal hexagonal sleeve 401 and the straight handle insulating operating inner rod 2. During the fastening operation, the spring device 202 is used to tightly fit the sleeve and the wire clamp bolt, avoiding the phenomenon that the sleeve and the bolt do not match. The limit frame 3 also prevents the situation that the positions of the two split wire clamps are jammed, increasing the smoothness of the operation, thereby realizing single-person operation, with the effects of high efficiency and convenience, and greatly reducing the time cost of the connection operation.
