[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: an insulated drain wire connection device for live-line electrical work, including a T-shaped frame 1. Two sets of upper arc-shaped clamping blocks 2 are fixedly welded to the upper two sides of the T-shaped frame 1. Threaded rods 3 are threadedly installed on the lower two sides of the T-shaped frame 1. The upper arc-shaped clamping blocks 2 are rotatably installed on the upper part of the threaded rods 3. Rotating the threaded rods 3 can drive the lower arc-shaped clamping blocks 4 to move up and down, cooperating with the upper arc-shaped clamping blocks 2 to clamp the drain wire or main line. Limiting grooves 5 are opened on both sides of the middle of the T-shaped frame 1. A limiting plate 6 is fixedly welded to one side of the upper arc-shaped clamping block 2. The limiting grooves 5 restrict the limiting plate 6 to move only in the vertical direction, preventing the lower arc-shaped clamping block 4 from shifting. To ensure clamping stability, the limiting plate 6 is fixedly welded to the limiting groove 5 with a first locking tooth 7. The front side of the T-shaped frame 1 is threadedly connected to the mounting box 8. Two sets of sliding rods 9 are slidably installed inside the mounting box 8. A connecting plate 10 is fixedly welded to one end of the sliding rod 9. A second locking tooth 11 that engages with the first locking tooth 7 is fixedly welded to one side of the connecting plate 10. A connecting piece 14 is fixedly welded to the outside of the sliding rod 9. A spring 15 is fixedly welded between the connecting piece 14 and the mounting box 8. The spring 15 is sleeved on the outside of the sliding rod 9. The elastic force of the spring 15 pushes the second locking tooth 11 to engage with the first locking tooth 7, thereby locking the position of the lower arc-shaped clamping block 4.

[0020] A pull plate 12 is fixedly welded to the other end of the sliding rod 9. An insulating sleeve 13 is fitted on the outside of the pull plate 12. When it is necessary to adjust the lower arc-shaped clamp 4, the operator pulls the pull plate 12, which causes the sliding rod 9 to compress the spring 15, so that the second locking tooth 11 is separated from the first locking tooth 7. At this time, the threaded rod 3 can be rotated to adjust the height of the lower arc-shaped clamp 4. After the adjustment is completed, the pull plate 12 is released, the spring 15 returns to its original position and pushes the second locking tooth 11 to engage again, thus completing the locking.

[0021] An isolation plate 16 is fixedly welded inside the T-shaped frame 1. The isolation plate 16 is set between the two limiting plates 6 to prevent the two limiting plates 6 from interfering with each other.

[0022] The T-shaped frame 1 has alignment lines 17 on both sides that are directly opposite the second locking teeth 11. The alignment lines 17 facilitate observation of the engagement state of the second locking teeth 11.

[0023] A protective shell 21 is fitted over the connecting piece 14 and the spring 15. One end of the protective shell 21 has a connecting groove 22 that engages with the pull plate 12. When the second locking tooth 11 engages with the first locking tooth 7, the pull plate 12 enters the connecting groove 22 and protrudes outwardly. This not only closes the connecting groove 22 but also facilitates the operation of the pull plate 12. Mounting pieces 23 are fixedly welded to the upper and lower sides of the protective shell 21. Threaded holes 24 are provided inside the mounting pieces 23 and on the upper and lower sides of the mounting box 8. The protective shell 21 is fixed by the mounting pieces 23, which protects the connecting piece 14 and the spring 15 and extends the service life of the device. The mounting box 8 can be removed through the threaded holes 24 and replaced with the spring 15 and other structures.

[0024] A rotating shaft 18 is rotatably mounted on the middle of one side of the pull plate 12. A baffle 19 is fixedly welded to the other end of the rotating shaft 18. A torsion spring 20 is fixedly welded between the baffle 19 and the pull plate 12. The torsion spring 20 is sleeved on the outside of the rotating shaft 18. When the pull plate 12 is fully pulled out, the baffle 19 is brought to a horizontal position by rotating the rotating shaft 18. The spring 15 pulls the connecting piece 14, which in turn causes the baffle 19 to press against the protective shell 21. The side of the baffle 19 facing the protective shell 21 is set as a high-friction surface, which can lock the spring 15 and facilitate the operation of the threaded rod 3. After the threaded rod 3 is operated, the baffle 19 is pushed with force. The baffle 19 is brought to a vertical position under the pull of the torsion spring 20, which facilitates the smooth passage of the connecting groove 22.

[0025] Working principle: When using this utility model, the operator pulls the pull plate 12, which drives the sliding rod 9 to compress the spring 15, causing the second locking tooth 11 to separate from the first locking tooth 7. Rotating the threaded rod 3 can drive the lower arc-shaped clamping block 4 to move up and down, cooperating with the upper arc-shaped clamping block 2 to clamp the drain line or main line. After adjustment, the pull plate 12 is released, and the elastic force of the spring 15 pushes the second locking tooth 11 to mesh with the first locking tooth 7, realizing the position locking of the lower arc-shaped clamping block 4.
