[0002] An electric wire is a conductor that carries electric current. It usually consists of one or more flexible conductors covered with a soft outer sheath. When installing, using, or processing electric wire products, the wires are usually cut to suit different usage scenarios.

[0003] Currently, most wire cutting methods use wire cutters. However, wire cutters can only easily cut thinner wires. Cutting thicker wires is laborious and troublesome, causing inconvenience to operators and making them impractical. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wire cutting device that can cut wires of different thicknesses, making it more convenient and labor-saving to cut thicker wires, bringing convenience to operators and improving practicality.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting device, comprising a base, a cutting mechanism, and a clamping mechanism. The cutting mechanism includes a fixed frame, which is fixedly connected to the center of the top of the base. A guide post is slidably mounted on the top of the fixed frame, and a cutter holder is fixedly connected to the bottom of the guide post. A wire cutting blade is mounted on the cutter holder. A support plate is fixedly connected between the inner walls of the left and right sides of the fixed frame, and a cutting groove is formed through the support plate. Two sets of brackets are symmetrically fixedly connected to the top of the fixed frame, and a rotating shaft is rotatably mounted on each set of brackets. A turntable is fixedly connected to each set of rotating shafts. The inner sides of the two sets of turntables are positioned near the edge. A connecting shaft is fixedly connected, and a transmission rod is rotatably mounted on the middle of the connecting shaft. A hinge seat is fixedly connected to the top of the guide column, and the bottom end of the transmission rod is rotatably connected to the hinge seat. A pressure handle is fixedly connected to the outer right side of each of the two sets of turntables, and a handle sleeve is fixedly fitted on the pressure handle. The clamping mechanism includes a motor, which is fixedly mounted on the top of the base. A bidirectional threaded rod is fixedly connected to the output end of the motor. The bidirectional threaded rod is rotatably mounted on a fixed frame. Two sets of clamping plates are screwed onto the bidirectional threaded rod. Each set of clamping plates has a guide opening. The two sets of clamping plates are symmetrically slidably mounted on the support plate through the cooperation of the guide openings, and the top of the clamping plates has a notch communicating with the guide opening.

[0007] Preferably, the top of the cutting blade is integrally connected to a docking plate, which has two sets of screw holes symmetrically opened. Two sets of wing bolts are symmetrically screwed onto the cutting blade holder. The docking plate is snapped onto the cutting blade holder, and the two sets of wing bolts are screwed into the two sets of screw holes respectively.

[0008] Preferably, the base has upright plates fixedly connected to both the front and rear sides at the top, and the top of each of the two upright plates is integrally connected to an arc-shaped support, with the top and bottom of the arc-shaped support flush with the top of the support plate.

[0009] Preferably, two sets of anti-slip pads are fixedly connected to the inner side of each of the two sets of clamps, and the two sets of anti-slip pads on the clamps are symmetrically distributed on both sides of the notch.

[0010] Preferably, the top two sides of the fixing frame are provided with clearance openings.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, by starting the motor, the distance between the two sets of clamping plates can be adjusted. This adjustment allows wires of different thicknesses to be clamped and fixed on the support plate. The notch design on the clamping plates allows them to clamp the wire from both sides of the cutting position without affecting the feed of the cutting blade, ensuring stable wire clamping. Rotating the turntable clockwise with the pressure handle provides sufficient downward force for the operator, offering a large torque. This allows the turntable to push the guide column downwards through the connection shaft and transmission rod, causing the guide column to push the cutter holder downwards. The cutter holder then pushes the cutting blade downwards, cutting the wire. The guide column's stroke allows the cutting blade to move into the cutting groove without hitting the bidirectional threaded rod, enabling the cutting of wires of different thicknesses. Cutting thicker wires is more convenient and labor-saving, improving operator convenience and practicality. Attached Figure Description

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0019] Please see Figures 1-5This utility model discloses a wire cutting device, comprising a base 1, a fixing frame 2, and a motor 7. The fixing frame 2 is fixedly connected to the center of the top of the base 1. A guide post 3 is slidably mounted on the top of the fixing frame 2. A cutter frame 4 is fixedly connected to the bottom of the guide post 3. A wire cutting blade 5 is mounted on the cutter frame 4. A support plate 6 is fixedly connected between the inner walls of the left and right sides of the fixing frame 2. A cutting groove is formed through the support plate 6. Two sets of brackets 19 are symmetrically fixedly connected to the top of the fixing frame 2. A rotating shaft 20 is rotatably mounted on each of the two sets of brackets 19. A turntable 21 is fixedly connected to each of the two sets of rotating shafts 20. A connecting shaft 22 is fixedly connected to the inner side of the base 1. A transmission rod 23 is rotatably mounted on the middle of the connecting shaft 22. A hinge seat 24 is fixedly connected to the top of the guide column 3. The bottom end of the transmission rod 23 is rotatably connected to the hinge seat 24. A pressure handle 25 is fixedly connected to the outer right side of each of the two sets of turntables 21, and a handle sleeve 26 is fixedly fitted on the pressure handle 25. A motor 7 is fixedly installed on the top of the base 1. A bidirectional threaded rod 8 is fixedly connected to the output end of the motor 7. The bidirectional threaded rod 8 is rotatably mounted on the fixed frame 2. Two sets of clamping plates 9 are screwed onto the bidirectional threaded rod 8. Guide openings 10 are opened on both sets of clamping plates 9. Two sets of clamping plates 9 are symmetrically slidably mounted on the support plate 6 through the cooperation of guide ports 10, and the top of the clamping plates 9 has a notch 11 communicating with the guide ports 10. In use, the distance between the two sets of clamping plates 9 can be adjusted by starting the motor 7. By adjusting the distance between the two sets of clamping plates 9, wires of different thicknesses can be clamped and fixed on the support plate 6. The notch design on the clamping plates 9 allows the clamping plates 9 to clamp both sides of the wire cutting position without affecting the feed of the wire cutter 5, ensuring the stability of the wire clamping. The turntable 21 is rotated clockwise by the pressure handle 25, and the pressure handle 25 is of sufficient length. The design facilitates downward force application by the operator, providing a larger torque. This allows the turntable 21 to push the guide column 3 downward through the cooperation of the connecting shaft 22 and the transmission rod 23. The guide column 3 then pushes the cutter holder 4 downward, which in turn pushes the wire cutter 5 downward. The downward movement of the wire cutter 5 cuts the wire. The travel of the guide column 3 allows the wire cutter 5 to move into the cutting groove without hitting the bidirectional threaded rod 8. This enables the cutting of wires of different thicknesses, saving time and effort when cutting thicker wires, providing convenience for the operator, and improving practicality.

[0020] The top of the cutting blade 5 is integrally connected to a docking plate 12. The docking plate 12 has two sets of screw holes 13 symmetrically opened. The cutting blade holder 4 is symmetrically screwed with two sets of wing bolts 14. The docking plate 12 is snapped onto the cutting blade holder 4, and the two sets of wing bolts 14 are screwed into the two sets of screw holes 13 respectively. In use, the cutting blade 5 is fixedly installed by snapping the docking plate 12 into the cutting blade holder 4 and then screwing the wing bolts 14 into the screw holes 13. This detachable structure allows the cutting blade 5 to be disassembled, repaired or replaced when the blade becomes dull.

[0021] The base 1 has upright plates 15 fixedly connected to the front and rear sides of the top. The top of each of the two upright plates 15 is integrally connected to an arc-shaped support 16. The top arc bottom of the arc support 16 is flush with the top of the support plate 6. When cutting the wire, the wire can be passed under the wire cutter 5 and placed on the arc support 16 to support the two sides of the wire cut, so that the wire is kept straight when it is cut.

[0022] Two sets of anti-slip pads 17 are fixedly connected to the inner side of both sets of clamping plates 9. The two sets of anti-slip pads 17 on the clamping plates 9 are symmetrically distributed on both sides of the notch 11. By setting the anti-slip pads 17, the clamping plates 9 can clamp the wires more tightly and securely.

[0023] Both sides of the top of the fixed frame 2 are provided with clearance openings 18; when the cutter frame 4 drives the cutting blade 5 to rise, the clearance openings 18 can be provided to avoid the cutting blade 5 and prevent the cutting blade 5 from colliding with the fixed frame 2.

[0024] This utility model discloses a wire cutting device. Its working principle is as follows: Initially, the wire cutter 5 is positioned in the cutting groove under gravity, while the pressure handle 25 is tilted downwards to the right. During use, the pressure handle 25 is used to rotate the turntable 21 counterclockwise, causing the wire cutter 5 to lift and disengage from the notch 11. The wire is then passed under the wire cutter 5 and rests on the support plate 6 and the arc-shaped support 16. The motor 7 is then activated, causing the clamping plates 9 to slide inwards along the support plate 6, bringing the two sets of clamping plates 9 closer together and securing the wire to the support plate 6. The notch design on the clamping plates 9 allows them to clamp the wire from both sides of the cutting position without affecting the wire cutter's feed, ensuring stable wire clamping. After the wire is secured, the pressure handle 25 is used to rotate the turntable 21 clockwise, allowing the turntable 21 to pass through the connecting shaft 22. The guide post 3 slides downward in cooperation with the transmission rod 23, which in turn pushes the cutter holder 4 downward. The cutter holder 4 then pushes the wire cutter 5 downward, and the wire cutter 5 cuts the wire by moving downward. The notch 11 allows the wire cutter 5 to pass through smoothly without interfering with its downward cutting. The stroke of the guide post 3 allows the wire cutter 5 to move down into the cutting groove on the support plate 6 without hitting the double-threaded rod 8. Thus, the wire is cut by the cooperation of the wire cutter 5 and the cutting groove. The pressure handle 25 is long enough to provide the operator with sufficient torque, making it easy for the operator to apply downward force and cut thicker wires smoothly. When the blade of the wire cutter 5 becomes dull, the wing bolt 14 is unscrewed from the screw hole 13, and the wire cutter 5 is disassembled for grinding, repair or replacement to ensure the cutting effect of the wire cutter 5.

[0025] The wire cutting device of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect; the motor 7 of the wire cutting device of this utility model is purchased from the market, and technicians in this industry only need to install and operate it according to the accompanying instruction manual.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
