[0001] This utility model relates to the field of cable cutting technology, specifically to a line modification and cutting device. Background Technology

[0002] Electricity lines are an important guarantee for ensuring power supply. With social development, residents' demand for electricity is also increasing. Moreover, electricity lines are exposed to the outside world for a long time, which can easily cause damage to the lines. Therefore, it is necessary to upgrade some aging and weakened lines to ensure residents' normal power supply needs. During the line upgrade process, the cables required for line laying need to be cut to a suitable length to meet the laying requirements.

[0003] Chinese utility model patent document CN219247320U discloses a wiring modification tooling. This device, through the arrangement of a first clamping seat, a second clamping seat, a notch, a hinge, a slider, a slide rail, a handle, a fixing block, a connecting plate, and bolts, facilitates back-and-forth sliding to cut cables. The matching of the first and second clamping seats ensures the cable is clamped and fixed, preventing displacement during cutting and resulting in a smoother cut. The device can clamp and fix cables of different models. However, in use, the appropriate notch size must be selected based on the cable diameter, increasing the workflow and affecting efficiency. Furthermore, if the notch size is inappropriate, the cable cannot be stably clamped and fixed, affecting the cutting quality. Utility Model Content

[0004] The purpose of this invention is to provide a circuit modification and cutting device to solve the problems existing in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A line modification cutting device includes a workbench, a cutting component at the rear end of the workbench, a saw kerf in the middle of the workbench, and an inclined clamping bar on each of the left and right sides of the rear end of the workbench, with the inclined surface of each clamping bar facing downward toward the cutting component so that the clamping bar forms a fixed angle with the top side of the workbench. A sliding groove is provided on each of the left and right sides of the saw kerf on the workbench, and a sliding rod is fixedly provided in each sliding groove along its central axis. A locking bar is slidably provided on the outer side of the sliding rod, with the top end of the locking bar vertically protruding from the sliding groove and protruding from the top side of the workbench. A limiting component is provided on the side wall of the workbench to limit the sliding of the locking bar along the sliding rod.

[0006] A further technical solution is that the left and right side walls of the workbench are respectively provided with slots that are connected to the corresponding end slide grooves. The locking bar is slidably placed in the slide groove and has a fixing rod on one end. One end of the fixing rod slides through the slot and protrudes from the side wall of the workbench.

[0007] A further technical solution is that the limiting component includes a tension spring and a fastener. A connecting bolt is rotatably provided on the side wall of the worktable at the end of the strip hole near the cutting component. One end of the tension spring is fixedly connected to the connecting bolt, and the other end is fixedly connected to the fastener. The fastener is provided with a buckle.

[0008] A further technical solution is to have a lever on the fastener.

[0009] A further technical solution is to provide a limiting block at the end of the fixing rod away from the clamping strip, and the width of the limiting block is greater than the width of the buckle.

[0010] A further technical solution is that the clamping bar has a clearance channel running through its central axis, the end of the clearance channel away from the cutting component is open, and the orthogonal projection of the clearance channel coincides with the slide groove.

[0011] A further technical solution is to provide a support spring on the slide bar, with the two ends of the support spring connected to the side of the clamping bar facing the cutting assembly and the groove wall of the slide, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When this device needs to cut a cable, the section of the cable to be cut is placed on the worktable. Then, the cable is pushed into a fixed angle formed between the clamping bar and the top side of the worktable, so that the outer side of the cable simultaneously contacts both the clamping bar and the top side of the worktable. The locking bar is then pushed to slide along the slide rod and contact the outer side of the cable. The locking bar is then limited by the limiting component. At this time, the clamping bar, the worktable, and the locking bar work together to clamp and fix the cable. Finally, the cable is cut by the cutting component and the saw kerf. With the above structure, the existing technology avoids the need to select an appropriate notch according to the diameter of the cable for clamping and fixing, which increases the workflow and affects the work efficiency. At the same time, it avoids the inability to stably clamp and fix the cable due to an unsuitable notch size, which affects the cutting quality. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0018] Example 1 Reference Figure 1 , Figure 2 This utility model discloses a line modification cutting device, including a workbench 1, a cutting component 2 at the rear end of the workbench 1, and a saw kerf 3 in the middle of the workbench 1. The cutting component 2 is a tabletop cutting machine, and its specific working principle is common knowledge to those skilled in the art. Those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge. There is an inclined clamping bar 4 on each of the left and right sides of the rear end of the workbench 1, and the inclined surface of each clamping bar 4 is inclined downward toward the cutting component 2 so that the clamping bar 4 forms a fixed angle with the top side of the workbench 1. There is a sliding groove 5 on each of the left and right sides of the saw kerf 3 on the workbench 1. A sliding rod 6 is fixed in each sliding groove 5 along its central axis. A locking bar 7 is slidably mounted on the outer side of the sliding rod 6. The locking bar 7 slides and fits against the groove wall of the sliding groove 5. The top of the locking bar 7 extends vertically out of the sliding groove 5 and protrudes from the top side of the workbench 1. There is a limiting component on the side wall of the workbench 1 to limit the sliding of the locking bar 7 along the sliding rod 6.

[0019] In this embodiment, when the cable needs to be cut, the section of the cable to be cut is placed on the workbench 1. Then, the cable is pushed into a fixed angle formed between the clamping bar 4 and the top side of the workbench 1, so that the outer side of the cable is in contact with both the clamping bar 4 and the top side of the workbench 1. The locking bar 7 is pushed to slide along the slide bar 6 and contact the outer side of the cable. Then, the locking bar 7 is limited by the limiting component. At this time, the clamping bar 4, the workbench 1 and the locking bar 7 cooperate to clamp and fix the cable. Finally, the cable is cut by the cutting component 2 and the saw kerf 3. With the above structure, the existing technology is avoided because it is necessary to select an appropriate notch according to the diameter of the cable to clamp and fix the cable, which increases the workflow and affects the work efficiency. At the same time, it avoids the inability to stably clamp and fix the cable due to the inappropriate selection of the notch size, which affects the cutting quality.

[0020] Example 2 Based on Example 1, referring to Figure 1 , Figure 2 The left and right side walls of the workbench 1 are respectively provided with strip holes 8 that are connected to the corresponding slide grooves 5. The locking bar 7 is slidably placed in the slide groove 5 and has a fixing rod 9 on one end. One end of the fixing rod 9 slides through the strip hole 8 and protrudes from the side wall of the workbench 1.

[0021] In this embodiment, by setting a fixing rod 9, it is easy to slide the locking strip 7 to fit the cable, and together with the clamping strip 4 and the worktable 1, the cable is clamped and fixed.

[0022] As a preferred implementation method, refer to Figure 1 , Figure 2 The limiting component includes a tension spring 10 and a fastener 11. A connecting bolt 12 is rotatably provided on the side wall of the worktable 1 at the end of the strip hole 8 near the cutting component 2. One end of the tension spring 10 is fixedly connected to the connecting bolt 12, and the other end is fixedly connected to the fastener 11. The fastener 11 is provided with a buckle 13.

[0023] Specifically, after the locking strip 7 slides and adheres to the cable, the fastener 11 is pulled, which in turn stretches the tension spring 10, and the buckle 13 on the fastener 11 is fastened to the fixing rod 9. Since the tension spring 10 is stretched and has elastic potential energy, it exerts a pulling force on the fixing rod 9. The fixing rod 9 transmits the tension to the locking strip 7, so that the locking strip 7 exerts pressure on the cable. Together with the clamping strip 4 and the worktable 1, the cable is clamped and fixed. At the same time, the locking strip 7 is subjected to tension, which prevents the locking strip 7 from sliding away from the cable along the slide rod 6, thus affecting the stability of clamping and fixing the cable. The buckle 13 can be set at an angle so that the fastener 11 is set in a hook shape to pull the fixing rod 9.

[0024] As a preferred implementation method, refer to Figure 1 , Figure 2The fastener 11 is equipped with a lever 14, which facilitates the pulling of the fastener 11.

[0025] As a preferred implementation method, refer to Figure 1 , Figure 2 A limiting block 15 is provided at the end of the fixing rod 9 away from the clamping strip 4, and the width of the limiting block 15 is greater than the width of the buckle 13.

[0026] Example 3 Based on Example 1, referring to Figure 1 , Figure 2 The clamping bar 4 has a clearance channel 16 extending through its central axis. The end of the clearance channel 16 away from the cutting component 2 is open, and the orthogonal projection of the clearance channel 16 coincides with the slide groove 5.

[0027] Specifically, by setting the clearance channel 16, when the locking bar 7 slides and fits against the cable, the locking bar 7 moves through the clearance channel 16 and will not collide with the clamping bar 4, ensuring that the locking bar 7 slides and fits against the cable, and works with the clamping bar 4 and the worktable 1 to clamp and fix the cable.

[0028] Example 4 Based on Example 2, referring to Figure 1 , Figure 2 A support spring 17 is fitted on the slide bar 6. The two ends of the support spring 17 are connected to the side of the clamping bar 4 facing the cutting assembly 2 and the groove wall of the slide 5, respectively.

[0029] In this embodiment, by setting a support spring 17, when the locking bar 7 slides against the cable, it will compress the support spring 17. After the cable is cut, the limiting component is unlocked, and under the action of the support spring 17, the locking bar 7 slides away from the cable along the slide bar 6, which makes it easier to remove the cable from the fixed angle formed by the clamping bar 4 and the worktable 1. There is no need to manually push the locking bar 7, which improves the portability of the device. It should be noted that when the fastener 11 is pulled and the tension spring 10 is stretched, and the buckle 13 on the fastener 11 is fastened to the fixed rod 9 to limit the locking rod, the elastic potential energy of the support spring 17 is less than the elastic potential energy of the tension spring 10.

[0030] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
