[0002] Low-voltage engineering cables refer to various wires and cable assemblies used in low-voltage systems to transmit low-voltage, low-current information such as signals, data, voice, and images. They are widely used in building intelligence, security monitoring, communication networks, and smart home fields. When using low-voltage engineering cables, it is necessary to cut them.
[0003] A cable cutting device disclosed in CN213645713U has support legs at all four corners of the bottom surface of the workbench; a cutting mechanism is set on the upper surface of the support frame; and a pull-out fixing mechanism is set on the bottom surface of the workbench. The upper end of the pull-out fixing mechanism is slidably connected to a T-slot, and the left side of the pull-out fixing mechanism is fixedly connected to the right end of a return spring. This device can cut multiple cables simultaneously, thereby improving the cutting efficiency of the device.
[0004] This cable cutting device can cut cables through its cutting mechanism, but after cutting the cable, the cutting mechanism cannot be folded and stored, making the device inconvenient for workers to carry. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this utility model is to provide a portable insulated wire cutter for low-voltage engineering, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable insulating wire cutter for low-voltage engineering, comprising a processing table, an insertion limiting mechanism provided on the outer side of the processing table, a wire cutting mechanism provided on the inner side of the insertion limiting mechanism, and a lower blade fixedly connected to the top of the processing table;
[0007] The insertion limiting mechanism includes an insertion component and a limiting component. The insertion component is disposed on the outside of the processing table, and the limiting component is disposed on the outside of the insertion component.
[0008] The plug-in assembly includes a fixed rod, which is fixedly connected to the front and rear sides of the processing table. A rotating frame is rotatably connected to the periphery of the fixed rod. A protective frame is fixedly connected to the front and rear sides of the rotating frame. A first threaded rod is rotatably connected to the inner side of the protective frame. A rotating disk is fixedly connected to the top of the first threaded rod. A threaded plate is threadedly connected to the periphery of the first threaded rod. A plug rod is fixedly connected to the inner bottom side of the threaded plate.
[0009] Preferably, the rotating frame and the inner side of the protective frame are provided with a sliding groove corresponding to the movement trajectory of the threaded plate, and the threaded plate is slidably connected to the inside of the sliding groove. The sliding groove can limit the movement of the threaded plate, making the threaded plate more stable during movement.
[0010] Preferably, the inner side of the processing table is provided with a fixing hole corresponding to the position of the insertion rod, and the insertion rod is inserted into the inner side of the fixing hole. Through the fixing hole, the insertion rod can be inserted into the processing table, which limits the rotation of the frame and makes it difficult for the frame to rotate.
[0011] Preferably, the limiting component includes a fixed frame, which is fixedly connected to the front and rear sides of the processing table. A second threaded rod is rotatably connected to the inner side of the fixed frame. The second threaded rod is rotatably connected to the inner side of the fixed frame. A rotating disk is fixedly connected to the right side of the second threaded rod. A movable plate is threadedly connected to the outer side of the second threaded rod. A linkage plate is fixedly connected to the front of the movable plate. A push plate is fixedly connected to the left side of the linkage plate. A gear is fixedly connected to the left side of the push plate. The gear meshes with a limiting gear on its left side. The limiting gear is fixedly connected to the front and rear sides of the rotating frame.
[0012] Preferably, the inner side of the fixed frame is provided with a limiting groove corresponding to the movement trajectory of the moving plate, and the moving plate is slidably connected inside the limiting groove. The limiting groove can limit the movement of the moving plate, making the moving plate more stable during movement.

[0014] Preferably, the top of the spring is fixedly connected to the bottom of the insulating pressure plate, and the bottom of the spring is fixedly connected to the top of the rotating frame. When the insulating pressure plate is not subjected to a downward force, the elastic force of the spring can drive the insulating pressure plate and the insulating rod to move upward, so that the insulating rod drives the insulating plate and the upper blade to move upward, and the upper blade moves upward to return to its original position.
[0015] Compared with the prior art, this utility model provides a portable insulated wire cutter for low-voltage engineering, which has the following advantages:
[0016] 1. In this portable insulated wire cutter for low-voltage engineering, the plug-in assembly uses a rotating disc to move a threaded plate via a first threaded rod. The threaded plate then moves the plug rod into the processing table, which limits the rotation of the rotating frame and makes the rotating frame more stable when the device cuts low-voltage engineering cables.
[0017] In the limiting assembly, when the rotating frame rotates to the left and is flush with the processing table, the operator manually rotates the rotating disk, which drives the second threaded rod to rotate. The second threaded rod then drives the linkage plate and push plate to move through the moving plate. The push plate then drives the shaping teeth to move, causing the shaping teeth to mesh with the limiting gear, thus limiting the rotation of the rotating frame. This makes the device easy for the operator to fold and store, and convenient for carrying after storage.
[0018] 2. In this portable insulated wire cutter for low-voltage engineering, when it is necessary to cut the cables for low-voltage engineering, the operator manually presses down the insulating pressure plate, so that the insulating pressure plate can move the insulating plate downward through the insulating rod, so that the insulating plate can move the upper blade downward, so that the upper blade and the lower blade can work together to cut the low-voltage engineering cables.

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.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] This utility model provides the following technical solution:
[0029] Example 1
[0030] Please see Figure 1-5 This utility model provides a technical solution: a portable insulating wire cutter for low-voltage engineering, including a processing table 1, an insertion limiting mechanism 2 is provided on the outside of the processing table 1, a wire cutting mechanism 3 is provided on the inside of the insertion limiting mechanism 2, and a lower blade 4 is fixedly connected to the top of the processing table 1.
[0031] The insertion limiting mechanism 2 includes an insertion component 21 and a limiting component 22. The insertion component 21 is disposed on the outside of the processing table 1, and the limiting component 22 is disposed on the outside of the insertion component 21.
[0032] The plug-in assembly 21 includes a fixed rod 211, which is fixedly connected to the front and rear sides of the processing table 1. A rotating frame 212 is rotatably connected to the periphery of the fixed rod 211. A protective frame 214 is fixedly connected to the front and rear sides of the rotating frame 212. A first threaded rod 213 is rotatably connected to the inner side of the protective frame 214. A rotating disk 215 is fixedly connected to the top of the first threaded rod 213. A threaded plate 216 is threadedly connected to the periphery of the first threaded rod 213. A plug rod 217 is fixedly connected to the inner side of the bottom of the threaded plate 216.
[0033] Furthermore, the inner sides of the rotating frame 212 and the protective frame 214 are provided with a sliding groove corresponding to the movement trajectory of the threaded plate 216, and the threaded plate 216 is slidably connected to the inside of the sliding groove. The sliding groove can limit the movement of the threaded plate 216, making the threaded plate 216 more stable during movement.
[0034] Furthermore, a fixing hole corresponding to the position of the insertion rod 217 is provided on the inner side of the processing table 1, and the insertion rod 217 is inserted into the inner side of the fixing hole. Through the fixing hole, the insertion rod 217 can be inserted into the processing table 1, which limits the rotation frame 212 and makes it difficult for the rotation frame 212 to rotate.
[0035] Example 2
[0036] Please see Figure 1-5 Furthermore, based on Embodiment 1, the limiting component 22 further includes a fixed frame 225, which is fixedly connected to the front and rear sides of the processing table 1. A second threaded rod 222 is rotatably connected to the inner side of the fixed frame 225. A rotating disk 224 is fixedly connected to the right side of the second threaded rod 222. A moving plate 223 is threadedly connected to the outer side of the second threaded rod 222. A linkage plate 226 is fixedly connected to the front of the moving plate 223. A push plate 227 is fixedly connected to the left side of the linkage plate 226. A toothed gear 228 is fixedly connected to the left side of the push plate 227. A limiting gear 221 meshes with the left side of the toothed gear 228. The limiting gear 221 is fixedly connected to the front and rear sides of the rotating frame 212.
[0037] Furthermore, a limiting groove corresponding to the movement trajectory of the moving plate 223 is provided on the inner side of the fixed frame 225, and the moving plate 223 is slidably connected to the inside of the limiting groove. The limiting groove can limit the movement of the moving plate 223, making the moving plate 223 more stable during movement.
[0038] Example 3
[0039] Please see Figure 1-5 Furthermore, based on Embodiment 1, the wire cutting mechanism 3 further includes an insulating rod 33, an insulating plate 32 fixedly connected to the bottom of the insulating rod 33, an upper blade 31 fixedly connected to the bottom of the insulating plate 32, an insulating pressure plate 34 fixedly connected to the top of the insulating rod 33, and a spring 35 sleeved around the insulating rod 33.
[0040] Furthermore, the top of the spring 35 is fixedly connected to the bottom of the insulating pressure plate 34, and the bottom of the spring 35 is fixedly connected to the top of the rotating frame 212. When the insulating pressure plate 34 is not subjected to downward force, the elastic force of the spring 35 can drive the insulating pressure plate 34 and the insulating rod 33 to move upward, so that the insulating rod 33 drives the insulating plate 32 and the upper blade 31 to move upward, so that the upper blade 31 moves upward and returns to its original position.
[0041] In actual operation, when this device is used and it is necessary to cut low-voltage engineering cables, the processing table 1 is placed in the working position, and the rotating frame 212 is pulled upward so that the rotating frame 212 is at a 90-degree angle to the processing table 1. The operator manually rotates the rotating disk 224, which drives the second threaded rod 222 to rotate. The second threaded rod 222 drives the linkage plate 226 and the push plate 227 to move through the moving plate 223. The push plate 227 drives the pick 228 to move, so that the pick 228 meshes with the limit gear 221, making it difficult for the rotating frame 212 to rotate. The operator manually rotates the rotating disk 215, which drives the first threaded rod 213 to rotate. The first threaded rod 213 drives the insert rod 217 to move through the threaded plate 216, so that the insert rod 217 can be inserted into the inside of the processing table 1, which plays a limiting role on the rotating frame 212.
[0042] Place the low-voltage engineering cable on the top of the processing table 1, so that the low-voltage engineering cable is between the upper blade 31 and the lower blade 4. The operator manually presses the insulating pressure plate 34 and moves it downward, so that the insulating pressure plate 34 drives the insulating rod 33 and the insulating plate 32 to move downward, so that the insulating plate 32 drives the upper blade 31 to move downward. When the insulating pressure plate 34 moves, it can squeeze the spring 35, so that the upper blade 31 moves downward to squeeze the low-voltage engineering cable. The upper blade 31 and the lower blade 4 work together to cut the low-voltage engineering cable.
[0043] After the device has cut the low-voltage cables, the operator rotates the rotating disk 215, causing the first threaded rod 213 to move the threaded plate 216 upwards. The threaded plate 216 then moves the insertion rod 217 upwards, allowing the insertion rod 217 to move away from the inside of the processing table 1. This allows the threaded plate 216 to move to the top inside the protective frame 214. The operator then rotates the rotating disk 224 again, causing the second threaded rod 222 to move. The second threaded rod 222, through the moving plate 223, moves the linkage plate 226 and the push plate 227, causing the push plate 227 to move. The tooth 228 is moved away from the limiting gear 221, allowing the rotating frame 212 to rotate to the left and be horizontal with the processing table 1. The operator then rotates the rotating disk 224, which drives the second threaded rod 222 to move the moving plate 223. The moving plate 223, through the linkage plate 226, drives the push plate 227 and the tooth 228 to move, so that the tooth 228 meshes with the limiting gear 221, limiting the rotating frame 212. This prevents the rotating frame 212 from rotating when the device is stored, making the device easy for the operator to carry.
