[0021] Referring to Figure 2 With Figure 3 As shown in the figure, in the embodiment: the bottom of U-shaped shell 12 is fixedly connected with first spring 13, the bottom of first spring 13 is fixedly connected with the top of base 8, when U-shaped shell 12 moves downward under the thrust of threaded push rod 11, U-shaped shell 12 presses first spring 13 and compresses to store energy, when staff removes the restraint of threaded push rod 11 to U-shaped shell 12, first spring 13 releases the force generated, rebounds and pushes U-shaped shell 12 to move upward, so that U-shaped shell 12 pops out from the two sides of limit plate 9, so as to facilitate staff to control the position of U-shaped shell 12 and remove the position restraint of U-shaped shell 12 to limit plate 9.
[0022] Referring to Figure 5 As shown in the figure, in the embodiment: the inner wall of one end of limit plate 9 is equipped with round corner 14, by the round corner 14, the inner wall surface of the front end of limit plate 9 is smooth, when contacting with T-shaped rod 7, T-shaped rod 7 is more easily slid into the inner wall of limit plate 9 through the characteristics of round corner 14, which is more conducive to the connection between components and improves the smoothness of component operation.
[0023] Reference Figure 4 As shown in this embodiment: a sliding groove 15 is provided inside the sliding rod 5, and a limiting post 16 is slidably connected to the inner wall of the sliding groove 15. The two ends of the limiting post 16 are fixedly connected to the inner wall of the sliding shell 4. When the sliding rod 5 slides on the inner wall of the sliding shell 4, the sliding connection between the sliding groove 15 and the limiting post 16 restricts the movement trajectory of the sliding rod 5 and the charge transfer device 6, ensuring the horizontal movement of the sliding rod 5 and the charge transfer device 6, and preventing the position of the charge transfer device 6 from shifting due to tilting when the sliding rod 5 moves.
[0024] Reference Figure 4 As shown in this embodiment: one end of the slide rod 5 is fixedly connected to a second spring 17, and the other end of the second spring 17 is fixedly connected to one side of the inner wall of the sliding shell 4. When the operator pulls the slide rod 5 to move it inside the sliding shell 4 so that the two charge transfer devices 6 merge, the slide rod 5 moves while pulling the second spring 17 to store force. When the operator releases the restraint of the limiting plate 9 on the position of the T-shaped rod 7, the second spring 17 will release the generated force and rebound to pull the slide rod 5 to move the charge transfer devices 6 to both sides, so that the two charge transfer devices 6 are away from the insulator body 3, so that the operator can quickly open the enclosure of the insulator body 3 by the charge transfer devices 6.

When the first spring 13 retracts and rebounds, the sliding connection between the first spring 13 and the protrusion on the top of the base 8 allows the first spring 13 to stick to the top surface of the base 8 when it rebounds upwards, thereby limiting the rebound trajectory of the first spring 13, preventing the first spring 13 from contracting inwards and causing curling and entanglement, and ensuring the smoothness of the first spring 13 when it moves up and down.
