[0020] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the conception of the present utility model belongs to the scope of protection required by the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a cutting device for power lines in power engineering, including a workbench 1. A pin shaft 2 is rotatably connected to the upper surface of the workbench 1. A rotating frame 3 is clamped outside the pin shaft 2. Both ends of the pin shaft 2 are connected to a first gear 4. Two through grooves 19 are formed in the workbench 1. Two pin rods 6 are connected in the through grooves 19. Two second gears 5 are rotatably connected outside the two pin rods 6. The two second gears 5 are meshed with each other. The two second gears 5 located above are both meshed with the first gear 4. The two second gears 5 located below are meshed with a rack 7. The second gears 5 are arranged in the through grooves 19 and are arranged between the first gear 4 and the rack 7. By setting the second gears 5, the rotating first gear 4 can drive the rack 7 to slide outside the guide rod 8 through the two meshed second gears 5;

[0022] Two guide rods 8 are slidably connected in the two racks 7. The two guide rods 8 are connected to the lower surface of the workbench 1. A first spring 9 is sleeved outside the guide rod 8. Both ends of the first spring 9 are respectively connected to the rack 7 and the guide rod 8. The two racks 7 are connected to the same connecting plate 10 on the side close to each other. By setting the guide rod 8 and the rack 7, the guide rod 8 can limit and fix the rack 7 below the workbench 1, so that the rack 7 can move along the axial direction of the guide rod 8;

[0023] A slide rod 11 is slidably connected in the connecting plate 10. One end of the slide rod 11 is connected to a movable clamping plate 12. A second spring 13 is sleeved outside the slide rod 11. Both ends of the second spring 13 are respectively connected to the movable clamping plate 12 and the connecting plate 10. By setting the second spring 13, the movable clamping plate 12 can fix the power line between the movable clamping plate 12 and the fixed clamping plate 15 under the action of the contracted second spring 13;

[0024] Two sliding grooves 14 are formed in the workbench 1. The movable clamping plate 12 is slidably connected in the two sliding grooves 14. By setting the sliding grooves 14 and the movable clamping plate 12, since the movable clamping plate 12 is slidably connected in the two sliding grooves 14, the sliding grooves 14 can limit the movable clamping plate 12, so that the movable clamping plate 12 is not easy to rotate during the movement, and the movable clamping plate 12 can move smoothly along the direction of the sliding grooves 14;

[0025] Two fixed clamping plates 15 are connected to the upper surface of the workbench 1. A cutting wheel 17 is rotatably connected inside the rotating frame 3. One end of the cutting wheel 17 is connected to the motor 18. Two protective covers 16 are connected to the upper surface of the workbench 1. Both of the first gears 4 are arranged inside the protective covers 16. By providing the protective covers 16, the protective covers 16 can block the first gears 4, making it difficult for the rotating first gears 4 to cause harm to the personnel around them.

[0026] The cutting wheel 17 is arranged between the two fixed clamping plates 15, and the movable clamping plate 12 corresponds to the positions of the two fixed clamping plates 15.

[0027] The working principle and usage process of the present utility model: When the device needs to be used, place the power line between the fixed clamping plate 15 and the movable clamping plate 12, and then press the rotating frame 3. The rotating rotating frame 3 drives the two first gears 4 to rotate through the pin shaft 2. Both of the rotating first gears 4 drive the rack 7 to move forward outside the guide rod 8 through the two meshing second gears 5, so that the two moving racks 7 drive the connecting plate 10 to move. The moving connecting plate 10 drives the movable clamping plate 12 to move in the two sliding grooves 14 towards the direction close to the fixed clamping plate 15 through the sliding rod 11 and the second spring 13, so that the movable clamping plate 12 and the fixed clamping plate 15 cooperate with each other to clamp and fix the power line. Continue to press the rotating frame 3, the rotating rod drives the cutting wheel 17 to move into contact with the power line, and then the working motor 18 drives the cutting wheel 17 to rotate to cut off the power line. During this process, the moving connecting plate 10 slides outside the sliding rod 11, and the second spring 13 contracts.
