[0022] 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.

[0023] Please see Figures 1-5 This utility model provides an electric ring device to avoid electric burns, including a positioning cylinder 1 and a sheath 2 disposed inside the positioning cylinder 1. A pull cable 3 is disposed inside the sheath 2. One end of the pull cable 3 is fixedly connected to a handle 4. The end of the pull cable 3 away from the handle 4 is fixedly connected to a connecting block 5. The end of the connecting block 5 away from the pull cable 3 is fixedly connected to a cutting line 6. A heat insulation sleeve 7 is covered on the surface of the cutting line 6. The heat insulation sleeve 7 is made of ceramic fiber material, which has good heat resistance and flexibility, and can shrink as the cutting line 6 shrinks.

[0024] In this embodiment, two tension spring ropes 8 are symmetrically fixedly connected to the surface of the connecting block 5. The two ends of the tension spring ropes 8 are fixedly connected to the connecting block 5 and the heat insulation sleeve 7, respectively. When the cutting line 6 wraps around the protrusion and retracts, the tension spring ropes 8 are in a relaxed state. When the cutting line 6 retracts to the point of detaching from the heat insulation sleeve 7, the tension spring ropes 8 will be forced to pull the heat insulation sleeve 7 and retract it, so as to prevent the heat insulation sleeve 7 from covering the heat source of the cutting line 6 due to synchronous retraction, which would cause cutting difficulties.

[0025] In this embodiment, a shrinkable mesh 9 is fixedly connected to the surface of the heat insulation sleeve 7. The shrinkable mesh 9 is made of ceramic fiber material, which has good heat resistance and flexibility. It can shrink as the heat insulation sleeve 7 shrinks, and can hold the cut protrusions for easy cleaning.

[0026] In this embodiment, a positioning groove 13 is provided inside the sheath 2. A connecting piece A10 is fixedly connected to the sheath 2 inside the positioning groove 13. A connecting piece B14 is attached to the surface of the connecting piece A10. The connecting piece B14 is electrically connected to the cutting line 6. A moving plate 11 is fixedly connected to the end of the connecting piece B14 away from the connecting piece A10. Two springs 12 are symmetrically fixedly connected to one side of the moving plate 11. The side of the springs 12 away from the moving plate 11 is fixedly connected to the sheath 2.

[0027] In this embodiment, the side of the movable plate 11 away from the galvanized sheet B14 is fixedly connected to a limiting post 15, and the handle 4 is located at the position of the limiting post 15 with a limiting groove 16. The end of the limiting post 15 away from the movable plate 11 is inserted into the limiting groove 16 and is slidably connected to the handle 4.

[0028] In this embodiment, the limiting groove 16 is composed of a rectangular structure and an arc-shaped structure.

[0029] The working principle of this utility model is as follows: When using this device, first place the positioning cylinder 1 in a suitable position, at which point the sheath 2 will be inserted into the body. Then, the cutting wire 6 is placed over the protrusion. At this time, the shrink net 9 will cover the protrusion, and the heat insulation sleeve 7 can prevent other surfaces of the cutting wire 6 from contacting other parts, thus preventing burns to other areas during use. Then, the cutting wire 6 is energized, and then the handle 4 is pulled. The connecting block 5 will pull the cutting wire 6 to retract, thereby cutting the protrusion. After the connecting block 5 slides a certain distance, the tension rope 8 will be forced to pull the heat insulation sleeve 7 to retract. At this time, the cutting wire 6 has been embedded in the protrusion. Inside, the heat insulation sleeve 7 prevents the heat generated by the cutting line 6 from being covered by the heat insulation sleeve 7 due to synchronous shrinkage, which would make cutting difficult. When the heat insulation sleeve 7 shrinks, it will drive the shrink net 9 to shrink, thereby catching the protrusion and making it easy to collect and clean the protrusion. When the handle 4 is pulled, the limiting post 15 will slide inside the limiting groove 16 until the cutting line 6 has finished cutting the protrusion. The limiting post 15 will slide to the arc groove. The spring 12 will push the limiting post 15 into the arc groove due to the elastic potential energy, so that the connecting piece B14 is away from the connecting piece A10 to achieve automatic power cut-off, preventing the operator from being burned if he fails to turn off the power in time.

[0030] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
