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] Example:

[0020] Please see Figure 1-6 This utility model provides a technical solution: an anti-backflow power supply device, including two connecting components. The upper connecting component is rotatably mounted with a first outer shell 1 and a second outer shell 2 via a connecting ear 8. The lower connecting component is snapped into the first outer shell 1 and the second outer shell 2. The two connecting components clamp the two ends of the first outer shell 1 and the second outer shell 2 to ensure that the first outer shell 1 and the second outer shell 2 stably clamp the wire.

[0021] The inner walls of the first outer shell 1 and the second outer shell 2 are respectively fixedly connected with a positive pole magnet 24 and a negative pole magnet 16. The first outer shell 1 and the second outer shell 2 can be clamped onto the wire in advance, so that the anti-backflow power supply device can be clamped onto the wire first, and the anti-backflow power supply device can be slid along the wire to insulate the stripped part of the wire.

[0022] A first connecting seat 10 is rotatably mounted on the surface of the first outer shell 1, and a first fastening head 11 is rotatably mounted on the first connecting seat 10. The first fastening head 11 is fastened to the second outer shell 2, so as to facilitate the fastening of the first outer shell 1 and the second outer shell 2.

[0023] In this embodiment, as Figure 6 As shown, the inner walls of the first outer shell 1 and the second outer shell 2 are both provided with grooves 23. The positive pole magnet 24 and the negative pole magnet 16 are located inside the corresponding grooves 23, keeping the inner walls of the first outer shell 1 and the second outer shell 2 smooth. The first outer shell 1 and the second outer shell 2 are in close contact with the wire, and the insulation effect is good.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the surface of the first connecting seat 10 is provided with a first arc groove 20, the first fastening head 11 is rotatably installed inside the first arc groove 20, and a stop post 21 is fixedly connected to the surface of the first connecting seat 10. The stop post 21 blocks the first fastening head 11. After the first connecting seat 10 and the first fastening head 11 are rotatably connected, the stop post 21 can prevent the first connecting seat 10 and the first fastening head 11 from separating.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the surface of the first outer shell 1 is provided with a first connecting block 9, and the first connecting seat 10 is rotatably connected to the first connecting block 9 through a first pin 22.

Just press the first fastening head 11.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the connecting assembly includes a third housing 3 and a fourth housing 4. The third housing 3 and the fourth housing 4 are respectively provided with a second connecting block 14 and a second fastener 13. The second connecting block 14 is equipped with a second connecting seat 6. The second connecting seat 6 is rotatably connected to the second connecting block 14 through a second pin 19. The second connecting seat 6 has a second arc groove 17. A second fastening head 7 that is fastened to the second fastener 13 is rotatably installed in the second arc groove 17 to ensure that the third housing 3 and the fourth housing 4 can be stably fastened.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the surface of the third outer shell 3 is provided with an elastic clip 15, and the surface of the second connecting seat 6 is provided with an anti-detachment head 18 that is inserted into the elastic clip 15. When the anti-detachment head 18 is inserted into the elastic clip 15, the third outer shell 3 and the fourth outer shell 4 will not be accidentally released after being fastened together.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the third outer shell 3 and the fourth outer shell 4 are rotatably connected by the cylindrical shell 5, and the third outer shell 3 and the fourth outer shell 4 can be rotatably opened.

[0029] Specifically, in use, lifting the second fastening head 7 to separate it from the second fastening seat 13 allows the third outer shell 3 and the fourth outer shell 4 to be opened. Lifting the first fastening head 11 to separate it from the first fastening seat 12 allows the first outer shell 1 and the second outer shell 2 to be rotated open. At this point, the first outer shell 1 and the second outer shell 2 can be placed on the wire. The negative magnet 16 and the positive magnet 24 can first fix the first outer shell 1 and the second outer shell 2 to the wire, ensuring that the first outer shell 1 and the second outer shell 2 will not fall off the wire. This is especially useful for multi-level applications at heights. When insulating a power wire, there is no need to frequently carry the anti-backflow device to prevent it from falling to the ground. Slide the first outer shell 1 and the second outer shell to the stripped part of the power wire, pull the first fastening head 11 and the first fastening seat 12 to align them, so that the first fastening seat 12 and the first fastening head 11 are fastened together. Pull the second fastening head 7 and the second fastening seat 13 to align them, so that the second fastening seat 13 and the second fastening head 7 are fastened together. This ensures that the first outer shell 1 and the second outer shell 2 clamp the power wire, and the third outer shell 3 and the fourth outer shell 4 also clamp the power wire, thus achieving insulation of the power wire.
