The rod 1 is made of insulating plastic. It should be noted that this design makes the rod 1 non-conductive, and the rotating base 11 is also made of insulating plastic.

[0026] like Figs. 1-2 As shown in one embodiment, a connecting plate is integrally formed in the center of the double-sided lock head 2, and is welded to the center of the top of the connector 25 through this connecting plate. It should be noted that the top view of the connector 25 is elliptical, and the height of the side of the connecting plate is greater than the diameter of the high-voltage wire.

[0027] like Figs. 1-2 As shown in one embodiment, the double-sided lock head 2 has two recessed openings of different sizes on the left and right sides near the connector 25. The rod body 1 is rotatably sleeved on the right side of the bottom of the connector 25. The shape and size of the left movable locking block 21 and the right movable locking block 22 match the shape and size of the recessed openings on both sides of the double-sided lock head 2. It should be noted that this design allows the double-sided lock head 2 to pull down the joints at both ends of two high-voltage wires to a low position for live-line connection.

The right lead screw 24 passes through the connector 25 and extends downward within the inner cavity of the rod body 1, where it is fixedly connected to the top center of the rotating base 11. It should be noted that this design allows the rotating base 11 to rotate, thereby causing the right movable locking block 22 to move up and down, enabling it to clamp high-voltage wires or double-ended cable connectors.

[0029] like Figs. 1-2 As shown in one embodiment, the top sections of the left lead screw 23 and the right lead screw 24 extend to the top block of the double-sided lock head 2 and are fixedly connected to a limiting hexagonal nut. The hexagonal nut has a through hole around its circumference. It should be noted that this design allows the operator to rotate the left lead screw 23 and the right lead screw 24 by rotating the two hexagonal nuts.

[0030] like Figs. 1-2 As shown in one embodiment, rollers are provided in the blocks of the left movable locking block 21 and the right movable locking block 22 near the top of the connecting member 25, and these rollers are rotatably connected to the left lead screw 23 and the right lead screw 24, respectively. It should be noted that this design ensures that the left movable locking block 21 and the right movable locking block 22 are not affected by external factors when they move up and down on the left lead screw 23 and the right lead screw 24.

[0031] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
