[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0040] like Figures 1-3 As shown, this embodiment provides a cable cutting device for electrical engineering, including a workbench body 1, a cutting unit and a clamping unit movably connected and fixed to the workbench body 1. The upper surface of the workbench body 1 is provided with an upward-facing first groove 11, and several limiting holes 12 are provided on both sides of the first groove 11. The limiting holes 12 at different positions can fix the cutting unit or the clamping unit, thereby adapting to the needs of cutting cables at different positions under different working conditions.

[0041] In this embodiment, as Figures 1-2As shown, the workbench body 1 is a rectangular plate-like structure that can be placed on the ground or on a tabletop. A first groove 11 with an upward opening is formed on the upper surface of the workbench body 1. The first groove 11 is elongated and extends along the length of the workbench body 1. Several limiting holes 12, which are threaded holes, are evenly distributed on both sides of the first groove 11. The workbench body 1 also has several downward-recessed receiving positions for accommodating clamping components located below. The limiting holes, separated by the receiving positions, are evenly spaced. The receiving positions include a first receiving groove 13 in the center and second receiving grooves 14 on both sides. The first receiving groove 13 is located within the first groove 11 and is recessed downwards. The second receiving groove 14 is located at the edge of the first groove 11 and is also recessed downwards. When the clamping member located below falls into the receiving position, the upper end surface of the clamping member located below is flush with the bottom surface of the first groove 11, which will not obstruct the movement of other clamping units or cutting units on the workbench body 1, thereby enabling them to move to the required clamping or cutting position. In this embodiment, the design of the first groove 11 provides flexible installation space and working area for the cutting unit and clamping unit, and allows for flexible adjustment of the cable cutting position after clamping and limiting the cable in electrical engineering construction. The design of several limiting holes 12 allows for flexible adjustment and fixed installation of the cutting unit and clamping unit, so that the cutting unit and clamping unit can be stably installed on the workbench body 1, facilitating cable cutting and clamping operations. In this embodiment, the cutting unit includes a cutting base 2 selectively connected to the limiting hole 12 and a cutting frame 3 fixed to the cutting base 2. The cutting frame 3 is adjustablely connected with a cutting blade 4. Specifically, the cutting base 2 includes a base plate 21, on which several sets of first arc-shaped grooves 22 are arranged. In this embodiment, three sets of first arc-shaped grooves 22 are arranged. A platform 23 is evenly arranged in the middle of each set of first arc-shaped grooves 22, wherein the platform 23 is perpendicular to the central axis of the first arc-shaped groove 22 and the platform 23 penetrates through the middle of each first arc-shaped groove. First mounting plates 24 are respectively arranged on the top of both sides of the base plate 21. In this embodiment, the base plate 21 and the first mounting plates 24 on both sides are integral structures. First through holes 25 are arranged on the first mounting plates 24, which are adapted to the limiting holes 12. The cutting base 2 is fixed to the corresponding limiting holes 12 of the workbench body 1 by bolts 5.

[0042] To go further, such as Figures 3-4As shown, the cutting frame 3 includes a gantry frame 31 and a rotating handle 32 threadedly connected to the top plate of the gantry frame 31. A threaded hole 33 is provided in the center of the top plate of the gantry frame 3, and the rotating handle 32 is threadedly connected to and passes through the threaded hole 33. The rotating handle 32 is T-shaped, and its vertical section has matching threads on its outer side wall. A connecting plate 34 is connected to the bottom end of the vertical section of the rotating handle 32, and a cutting blade 4 is fixedly attached to the lower end face of the connecting plate 34. Rotating the rotating handle 32 can drive the connecting plate 34 and the cutting blade 4 to move up and down. When the cutting blade moves to the first arc-shaped groove 22 of the cutting base, it can cut the cable. As the cutting blade 4 continues to move downwards along the table opening 23, it can cut the cable completely. The bottom ends of both sides of the portal frame 31 are integrally provided with second mounting plates 35. The second mounting plates 35 are provided with second through holes 36, which are respectively adapted to the first through holes 25. By passing bolts 5 through the corresponding second through holes 36 and first through holes 25, the cutting frame 3 is fixed to the cutting base 2, and the cutting unit is fixed to the workbench body 1. In order to maintain stability during the cutting process, sliders 37 are provided on both sides of the connecting plate 34. Correspondingly, a sliding groove 311 is provided on the inner side of the side plate of the portal frame 31. The sliders 37 can move up and down along the sliding groove 311, thereby limiting the cutting blade and preventing the cutting blade from wobbling back and forth during the cutting process.

[0043] In this embodiment, the first arc-shaped groove 22 and the table opening 23 allow the cutting blade 4 to better adapt to the curvature of the cable when cutting, improving cutting accuracy and quality. The first mounting plate 24 and the first through hole 25 facilitate the fixed connection between the cutting base and the workbench body, ensuring the stability of the cutting unit during operation. Correspondingly, along with the design of multiple limiting holes 12 on the workbench body 1, the installation position of the cutting unit can be flexibly adjusted according to the actual working conditions of the electrical engineering.

[0044] In the cutting frame 3, the gantry frame 31 has a simple and stable structure, providing good support for the cutting blade. The cooperation between the rotating handle 32 and the threaded hole 33 makes the up-and-down movement of the cutting blade more convenient and flexible. The feeding and retraction operations of the cutting blade 4 can be realized by rotating the rotating handle 32. The sliders on both sides of the connecting plate 34 and the sliding grooves 311 on the inner side of the side plate of the gantry frame 31 guide the movement of the connecting plate 34, ensuring that the cutting blade 4 remains stable during up-and-down movement and preventing the cutting blade 4 from deviating during the cutting process, thereby improving the cutting accuracy and quality.

[0045] In this embodiment, as Figure 1 , Figures 5-7As shown, the clamping unit includes two sets of clamping members 6 arranged vertically opposite each other for clamping cables. Specifically, the clamping member 6 is a plate 61 with several second arc-shaped grooves 62. Third mounting plates 63 are fixed to the top of both sides of the plate 61. Third through holes 64 are provided on the third mounting plates 63, which are adapted to the limiting holes 12. The clamping member 6 is fixed to the limiting holes 12 of the workbench body 1 by bolts 5. A limiting sleeve 65 is fixed inside the second arc-shaped groove 62. A connecting rod 63 is arranged inside the limiting sleeve 65. A cable tie 67 is fixed to the top of the connecting rod 66, and a spring 68 is fixed to the bottom of the connecting rod 63. The bottom of the spring 68 is fixed to the inner wall of the second arc-shaped groove 62. In this embodiment, the receiving position in the workbench body 1 can accommodate the clamping member 6 located below. When the clamping member 6 falls into the receiving position, its upper end surface is flush with the bottom surface of the first groove 11. This avoids the clamping member 6 protruding too high on the workbench body, affecting the movement of the cutting unit and the cutting operation. It also makes the surface of the workbench body 1 flatter, facilitating the placement and movement of cables. To facilitate the movement of each clamping member 6, a handle 69 is also provided on the outer side of the third mounting plate 63 to facilitate the movement of each clamping member 6.

[0046] In the clamping component, the second arc-shaped groove 62 can fit against the outer surface of the cable, improving clamping stability. The third mounting plate 63 and the third through hole 64 facilitate the fixed connection between the clamping component and the main body of the workbench, ensuring the stability of the clamping unit during operation. The limiting sleeve 65 can limit the connecting rod 63, ensuring the stability of the connecting rod 63 during movement. When the two clamps 6 are interlocked, the cable clamp 67 at the top of the connecting rod 63 is used to clamp the cable. Through the elastic action of the spring 68, the cable clamp can apply a certain clamping force to the cable, thereby achieving reliable clamping of the cable.

[0047] The electrical engineering cable cutting device provided in this embodiment has equal spacing between the limiting holes 12 on the main body 1 of the workbench. The cutting unit and the clamping unit can be fixed by selecting different limiting holes 12 according to the actual cable cutting needs, thereby realizing the position adjustment of the cutting unit and the clamping unit to adapt to the cutting needs of cables of different lengths and diameters. This improves the applicability and versatility of the device, reduces production costs, and also makes it convenient for workers to use it flexibly according to different work scenarios.

[0048] The electrical engineering cable cutting device provided in this embodiment has a cutting unit and a clamping unit that can be movably connected and fixed to the workbench body 1. The cutting blade 4 of the cutting unit can be easily moved up and down by rotating the handle 32, and the clamping part 6 of the clamping unit can be quickly fixed and disassembled by bolts 5. This makes the operation of the entire device simple and quick, and facilitates the cutting and clamping of cables by the staff.

[0049] The design of the first arc groove 22 and the table opening 23 of the cutting base 2, as well as the cooperation between the sliders 37 on both sides of the connecting plate 34 and the slide groove 311 in the cutting frame 3, can ensure that the cutting blade 4 remains stable during the cutting process and can better adapt to the curvature of the cable, thereby improving the cutting accuracy and quality, ensuring that the cut cable end face is flat and smooth, and meeting the requirements for cable cutting accuracy in electrical engineering.

[0050] The clamping unit 6, through the second arc groove 62, fits against the outer surface of the cable, and with the cooperation of the limiting sleeve 65, connecting rod 63, cable tie 67 and spring 68, can apply a stable clamping force to the cable and play a buffering role in the cutting process, preventing the cable from loosening or being damaged during the cutting process, ensuring the smooth progress of the cutting process, and improving the safety and reliability of the cutting.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
