[0002] In power engineering, in order to make electrical components work, it is necessary to provide power or electrical signals to them. Therefore, cables need to be used for connection. Since each signal base station uses a relatively large number of electrical components, the types and lengths of the cables used are different, and the length used also needs to be determined during on-site installation. Therefore, it is necessary to carry a large number of various types of cables. Since the cables are relatively heavy and not easy to move, a cable cutting device that is easy to carry is needed to cut them.

[0003] Publication No. CN217642386U discloses a cable cutting device, including a fixed seat and a guillotine. A groove is opened on the fixed seat, and the guillotine is arranged in the groove.

[0026] Please refer to Figures 1-5 , on the side of the fixed seat 1, a side block 5 is fixedly installed. The side block 5 is a "U" - shaped structure and is made of austenitic stainless steel, having excellent corrosion resistance and high strength, and can be used for a long time in a harsh working environment. Inside the side block 5, a rotating rod 6 is rotatably connected. At one end of the rotating rod 6, a short block 7 is fixedly installed. A plug rod 8 is disposed through the side surface of the short block 7. At one end of the plug rod 8, a round block 9 is fixedly installed. A tension spring 10 is sleeved on the surface of the plug rod 8. One end of the tension spring 10 is fixedly connected to the round block 9, and the other end of the tension spring 10 is fixedly connected to the short block 7. The tension spring 10 can generate a pulling force to pull the round block 9 to move. The tension spring 10 can be made of materials such as spring steel, rubber spring and gas spring. Among them, spring steel has high strength and good elasticity and is suitable for most working environments; rubber spring has good corrosion resistance and flexibility and is suitable for special environments; gas spring can provide stable pulling force and buffering effect and is suitable for occasions that require precise control. On the side surface of the side block 5, a jack A11 and a jack B12 are opened. On the surface of the rotating rod 6, a measuring scale 13 is fixedly installed. The measuring scale 13 is used to measure the length of the cable.

[0027] Embodiment Two

[0028] Please refer to Figures 4-5, an extension mechanism is provided at the top end of the measuring ruler 13. The extension mechanism includes an extension ruler 16 which is disposed through the top end of the measuring ruler 13. A top block 17 is fixedly installed on the surface of the extension ruler 16, and a bottom block 18 is fixedly installed on the surface of the measuring ruler 13. A long rod 19 is fixedly installed on the bottom surface of the top block 17. The long rod 19 is slidably connected to the bottom block 18, and a magnet 20 is fixedly installed at the bottom end of the long rod 19. The extension ruler 16 can be slidably connected to the measuring ruler 13 through a guide rail or a chute, ensuring the smoothness and precision of the extension ruler 16 during sliding. The guide rail connection method can provide good guiding and stability, while the chute connection can adapt to different size requirements.

[0029] Working principle: When the cable needs to be cut, just place the cable in the wire groove 3, and then press the cutter 4 through the pressing handle 15 until the cutter 4 cuts off the cable. At the same time, when the staff cuts the cable, the staff can pull the round block 9, and the round block 9 can then drive the insertion rod 8 to leave the jack A11. Then rotate the measuring scale 13 counterclockwise. At this time, the measuring scale 13 can be laid flat. Then release the round block 9. At this time, due to the pulling force of the tension spring 10, the tension spring 10 can pull the round block 9 to move. The round block 9 can then drive the insertion rod 8 to insert into the jack B12. At this time, the measuring scale 13 can be limited. At this time, the length of the cable can be conveniently measured through the measuring scale 13, so as to mark the position on the cable that needs to be cut. When the measuring scale 13 is not in use, the staff only needs to adjust the measuring scale 13 to the erected position to retract the measuring scale 13, so as to avoid the measuring scale 13 interfering with the normal work. Through the design of the measuring scale 13 in the present utility model, the operator can conveniently measure the length of the cable when cutting the cable and mark the position that needs to be cut, so as to ensure the cutting accuracy and avoid errors. When the length of the cable needs to be measured, only need to pull the round block 9 and rotate the measuring scale 13 counterclockwise to expand the measurement. The operation is simple and convenient without complex steps. At the same time, the design of the measuring scale 13 enables the measurement and cutting to be completed on the same device, reducing the operation steps and the required tools, thereby improving the work efficiency. And when the measuring scale 13 is not in use, the measuring scale 13 can be adjusted to the erected position, and it will not interfere with the normal cutting operation after being retracted, ensuring the simplicity of the device and the smoothness of the operation. When a longer measuring scale 13 is needed, the staff only needs to pull the extension scale 16 upward. At this time, the extension scale 16 can slide upward inside the measuring scale 13. The extension scale 16 can then drive the long rod 19 to move upward through the top block 17. The long rod 19 can then drive the magnet 20 to move until the magnet 20 abuts against the bottom block 18. At this time, due to the magnetic force, the magnet 20 can attract the bottom block 18 made of ferritic stainless steel. Through the design of the extension scale 16 in the present utility model, the device can extend the measurement length when needed to meet the measurement requirements of cables with different lengths and improve the applicability of the device. The design of the extension scale 16 enables the staff to simply pull the extension scale 16 upward to extend the measuring scale 13. The operation is convenient and fast without the need to replace tools or make complex adjustments. And the extension scale 16 drives the long rod 19 and the magnet 20 to move through the top block 17, and finally the magnet 20 attracts the bottom block 18. The magnetic force ensures the stability of the extension scale 16 during use and will not easily slide or come off.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
