[0002] In scenarios such as building construction and power engineering, cables need to be cut according to the actual wiring path and spatial layout to adapt to different installation requirements. For example, during home renovation, electricians need to cut cables to appropriate lengths according to the room size and circuit design to facilitate wiring in walls, floors, or ceilings. Existing cable cutting devices may use simple clamping or pressing methods to fix cables. This method is easily affected by vibration or external forces during the cutting process, causing the cable to move or deviate. For example, when the cutting device's blade applies a large cutting force to the cable, the cable may slip at the clamping point, thus affecting the cutting accuracy and quality. Utility Model Content

[0003] The purpose of this invention is to provide a cable cutting device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a cable cutting device is provided, including a base, a cable placed above the base, a cutting assembly disposed above the base, the cutting assembly reciprocating to cut the cable, a truss fixedly installed above the base, and a positioning device slidably disposed below the truss. The positioning device radially compresses and fixes the cable from both sides of the cutting assembly. When the positioning device slides, it causes the cutting assembly to slide, increasing the distance between the positioning device, the cutting assembly, and the base. A groove is provided above the base, and the cable passes through the positioning device and the cutting assembly and is placed in the groove.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, this embodiment provides a cable cutting device, including a base 32. A cable is placed on top of the base 32, which serves as the basic support structure for the entire device, providing a stable platform for the cable. A groove is designed on the base 32, through which the cable passes. The shape and size of the groove match the outer diameter of the cable, ensuring the cable maintains a stable position during cutting and preventing displacement due to vibration or external forces, thereby improving cutting accuracy and reliability. A cutting assembly 2 is disposed above the base 32, reciprocating to cut the cable. A truss 31 is fixedly installed above the base 32, and a positioning device 1 is slidably disposed below the truss 31. The truss 31 provides additional support and structural stability for the device. The structural strength enhances the stability of the overall device. Its design not only withstands various forces generated during the cutting process, but also provides guidance and support for the installation and movement of the cutting component 2 and the positioning device 1. The positioning device 1 radially compresses and fixes the cable from both sides of the cutting component 2. When the positioning device 1 slides, it drives the cutting component 2 to slide, increasing the distance between the positioning device 1, the cutting component 2 and the base 32. This distance adjustment mechanism allows the cutting component 2 to be appropriately adjusted according to the length of the cable and the cutting requirements, avoiding incomplete cutting or damage due to the distance being too close or too far. When the distance between the cutting component 2 and the positioning device 1 reaches the appropriate position, the cutting component 2 continues to reciprocate to complete the cutting of the cable.

[0024] The positioning device 1 includes a balance plate 12, which is slidably inserted into the lower part of the truss 31. This sliding insertion design allows the balance plate 12 to move flexibly horizontally under the support of the truss 31, facilitating the positioning and fixing of cables. By adjusting the position of the balance plate 12, it can accommodate cables of different diameters and lengths, improving the applicability and flexibility of the device. It also ensures the stability of the cable during the cutting process, reducing cutting errors caused by inaccurate cable positioning. A grooved plate 13 is fixedly connected below the balance plate 12, and a saw blade 24 is installed below the grooved plate 13. The saw blade 24 reciprocates to cut the cable located below it. The reciprocating saw blade 24 can quickly... The saw blade 24 is cut off quickly, reducing the cutting time and improving production efficiency. At the same time, the design of the slotted plate 13 provides guidance and support for the movement of the saw blade 24, ensuring the smoothness and reliability of the cutting process. When the slotted plate 13 moves away from the base 32, it drives the saw blade 24 away from the cable. This design can not only adjust the distance between the cutting device and the cable to adapt to different cutting requirements and cable diameters, but also provide a certain degree of safety protection during the cutting process. When it is necessary to replace the saw blade 24 or perform other maintenance operations, the position of the slotted plate 13 can be adjusted to move the saw blade 24 away from the cable, thereby avoiding damage to the cable or operators during operation, improving the safety and maintenance convenience of the device.

[0025] Side plates 14 are fixedly connected to both sides of the slot plate 13. Telescopic rods 15 are slidably inserted into both ends of the side plates 14. This sliding insertion structure allows the telescopic rods 15 to move flexibly with the support of the side plates 14, which facilitates the positioning and fixing of the cable. It also improves the adaptability and flexibility of the device, enabling it to adapt to cables of different diameters and lengths. A pressure plate 16 is fixedly connected to the lower end of the telescopic rod 15. A slot is provided in the middle section of the pressure plate 16. The two pressure plates 16 are located on both sides of the saw blade 24. The two pressure plates 16 press and fix the cable from both sides of the saw blade 24. This pressing and fixing method can effectively fix the cable in the cutting position, prevent the cable from rotating or shifting during the cutting process, and ensure the accuracy and consistency of the cutting. At the same time, the slot design allows the cut position of the cable to be stably fixed between the slot and the groove of the base 32, further improving the cutting accuracy and stability, reducing the cutting error caused by inaccurate cable position, and improving the cutting quality.

[0026] A spring is fitted around the telescopic rod 15, positioned between the side plate 14 and the pressure plate 16. The spring pushes the pressure plate 16 downwards, causing it to press the cable downwards. When the spring is in its natural state, its elastic force pushes the pressure plate 16 downwards, pressing it firmly against the cable and fixing it in the cutting position. This automatic compression fixing method not only improves the efficiency of cable fixing but also ensures the stability of the cable during the cutting process, reducing cable deviation or damage caused by improper human operation and improving cutting accuracy and quality. When the spring is compressed, the top of the telescopic rod 15 slides upwards towards the side plate 14. This design allows the pressure of the pressure plate 16 on the cable to be quickly released by compressing the spring when the position of the pressure plate 16 needs to be adjusted or the cable replaced, allowing the pressure plate 16 to move upwards, thus facilitating the insertion or removal of the cable. At the same time, the sliding of the telescopic rod 15 also provides space for the compression and reset of the spring, ensuring the normal operation of the device. This structural design not only improves the ease of operation of the device but also enhances its flexibility and adaptability, enabling it to better meet different cutting needs.

[0027] A groove is provided in the middle of the groove plate 13. A cutting cylinder 21 is fixedly connected to the top of the groove plate 13. The piston rod of the cutting cylinder 21 is fixedly connected to a sliding rod 22. The sliding rod 22 passes through the groove and is fixedly connected to a blade holder 23. The blade holder 23 is located below the groove plate 13 and slides back and forth. This groove structure not only improves the stability and accuracy of the movement of the cutting component 2, but also reduces friction and wear during the movement, extends the service life of the device, and ensures the continuity and reliability of the cutting process. The saw blade 24 is fixedly installed below the blade holder 23. The cutting cylinder 21 pushes the saw blade 24 to reciprocate through the piston rod to cut the cable, realizing fast and accurate cutting of the cable, improving cutting efficiency and quality, and also reducing the labor intensity of the operator.

[0028] A positioning cylinder 11 is fixedly installed below the truss 31. The piston rod of the positioning cylinder 11 is fixedly connected to the balance plate 12. The positioning cylinder 11 pushes the balance plate 12 and the slot plate 13 downward through the piston rod, providing a stable foundation for subsequent cable fixing and cutting operations, improving the automation level and work efficiency of the device. The downward moving slot plate 13 pushes the pressure plates 16 on both sides downward, so that the pressure plates 16 contact the base 32, which can firmly fix the cable on the base 32 and prevent the cable from moving or shifting during the cutting process.

[0029] In practical use, the cable cutting device of this embodiment places the cable to be cut above the base 32, ensuring that the cable passes through the groove on the base 32 to facilitate subsequent positioning and cutting operations. The positioning cylinder 11 is activated, and its piston rod pushes the balance plate 12 downward, causing the groove plate 13 to move downward synchronously. The downward movement of the groove plate 13 pushes the pressure plates 16 on both sides to move downward as well, until the pressure plates 16 contact the base 32, firmly fixing the cable to the base 32 and preventing the cable from moving or shifting during the cutting process. Driven by the cutting cylinder 21, the saw blade 24 cuts the cable with continuous and stable movements until the cable is neatly cut. After the cutting is completed, the positioning cylinder 11 is closed, causing its piston rod to retract, which drives the balance plate 12, groove plate 13 and pressure plate 16 to move upward, loosening the fixation on the cable and making it easy to take out the cut cable.
