Technical Field
[0001] This utility model relates to the field of power maintenance technology, and in particular to a wire cutter for power maintenance operations. Background Technology
[0002] Underground mining operations are complex and highly risky. The power system, as the key to ensuring the operation of various equipment, is of paramount importance for its stability. Inspecting underground power lines can promptly identify problems such as aging lines, short circuits, and equipment malfunctions, preventing serious safety accidents caused by power anomalies and ensuring the safety of miners and the normal operation of production. Wire cutters are indispensable in power maintenance. When encountering old or damaged wires that need replacement, or in emergencies requiring rapid circuit disconnection to prevent the spread of danger, wire cutters can quickly and efficiently cut the wires with their powerful shearing force, creating conditions for subsequent maintenance work to proceed smoothly.

[0023] 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.
[0024] Reference Figure 1-5A type of wire cutter for power maintenance work includes an upper clamp body 1, inside which a lower clamp body 2 is installed. A cutting assembly 3 is provided on the inner wall of the upper clamp body 1 and the top of the lower clamp body 2. The cutting assembly 3 includes a cutting groove 301, a cutting blade 302, a lifting slide 303, a wire support block 304, a lifting slider 305, a transmission slider 306, a transmission slide 307, a limiting groove 308, an adapter groove 309, and a wire inlet groove 310. The cutting groove 301 is formed on the bottom inner wall of the upper clamp body 1, and the cutting blade 302 is fixedly installed inside the cutting groove 301. The slide groove 303 is opened on the side of the upper clamp 1 near the lower clamp 2. The cable support block 304 is slidably connected to the inside of the lifting slide groove 303. The lifting slider 305 is fixedly connected to the side of the cable support block 304 near the lifting slide groove 303. The transmission slider 306 is fixedly connected to the bottom of the cable support block 304. The transmission slide groove 307 is opened on the top of the lower clamp 2. The limiting groove 308 is opened on the top of the cable support block 304. The adapter groove 309 is opened on the inner wall of the limiting groove 308. The cable inlet groove 310 is opened on the upper right side of the cable support block 304 and the lower right side of the upper clamp 1, respectively.
[0025] The adapter groove 309 is adapted to the cutting blade 302, the transmission slide 307 is adapted to the transmission slider 306, the lifting slider 305 is adapted to the lifting slide 303, and the wire support block 304 is adapted to the cutting groove 301.
[0026] The transmission slider 306 and transmission groove 307 are inclined, and the limiting groove 308 is used to limit the wire. With the cutting assembly 3, the operator first holds the device, then guides the wire through the inlet groove 310 into the limiting groove 308. Next, the operator squeezes the lower clamp 2, causing it to rotate counterclockwise. Then, through the adaptation of the transmission slider 306 and transmission groove 307, the wire support block 304 moves upward through the lifting groove 303 and into the cutting groove 301. When the wire support block 304 moves to the appropriate position, the cutting blade 302 cuts the wire inside the limiting groove 308. This invention, by squeezing the lower clamp 2, causes it to rotate while simultaneously raising the wire support block 304, thus cutting the wire at its top. This significantly reduces the operator's physical activity, allowing the device to be used even in confined spaces, effectively improving the convenience of wire cutting and increasing the operator's work efficiency.
[0027] Furthermore, a rotating groove 4 is provided inside the middle of the upper clamp body 1, and a fixed rotating shaft 5 is rotatably connected to the middle of the lower clamp body 2. The lower clamp body 2 is rotatably connected to the inside of the rotating groove 4 through the fixed rotating shaft 5, and support baffles 6 are fixedly connected to the front and rear ends of the wire support block 304.
[0028] The opening of the rotating groove 4 facilitates the rotation of the lower clamp body 2. The fixed rotating shaft 5 is used to rotatably connect the upper clamp body 1 and the lower clamp body 2. The support baffle 6 is used to support the wire.
[0029] Furthermore, a fixing component 7 is provided on the inner wall of the side of the upper clamp body 1. The fixing component 7 includes a movable slide 701, a limiting slide 702, a fixing clamp 703 and a coil spring 704. The movable slide 701 is respectively opened on the inner wall of the front and rear ends of the upper clamp body 1.
[0030] The limiting groove 702 is formed on the inner wall of the movable groove 701. The fixed clamp 703 is slidably snapped into the inside of the movable groove 701. The helical spring 704 is fixedly connected to the side of the fixed clamp 703, and the other end of the helical spring 704 is fixedly connected to the side wall of the movable groove 701.
[0031] The fixing clamp 703 is adapted to the limiting slide groove 702. The side of the fixing clamp 703 away from the helical spring 704 has an arc-shaped groove. The fixing component 7 is set so that when the wire support block 304 moves the wire upward, the wire can be clamped and fixed by the support baffle 6 and the fixing clamp 703. Then, as the wire support block 304 continues to move upward, the support baffle 6 will push the fixing clamp 703, thereby causing the helical spring 704 to retract. The reaction force of the helical spring 704 will push the fixing clamp 703 to clamp and fix the wire, so that the wire can be stable during the cutting process. This utility model, through the cooperation of the support baffle 6, the fixing clamp 703 and the helical spring 704, can clamp the wire at all times when the wire support block 304 moves the wire up and down, preventing the wire from falling before or after cutting, and effectively improving the safety and stability of the wire placement.
[0032] Furthermore, a cable routing slope 8 is provided on the upper right side of the upper clamp body 1, and handles 9 are fixedly connected to the bottom of both the upper clamp body 1 and the lower clamp body 2. A spiral spring 10 is fixedly connected inside the cutting groove 301.
[0033] The opening of the cable ramp 8 facilitates the removal of other excess wires and makes it easier for staff to accurately cut problematic wires. The installation of the handle 9 provides insulation. The other end of the spiral spring 10 is fixedly connected to the cable support block 304. The installation of the spiral spring 10 can reset the cable support block 304.
[0034] In summary:
[0035] When using this utility model, first hold the device, then let the wire enter the limiting groove 308 through the wire inlet groove 310, then squeeze the lower clamp 2 to make the lower clamp 2 rotate counterclockwise, and then drive the wire support block 304 to move upward through the lifting groove 303 through the adaptation of the transmission slider 306 and the transmission groove 307, and enter the cutting groove 301. When the wire support block 304 moves to the appropriate position, the wire inside the limiting groove 308 can be cut by the cutting blade 302.
[0036] Furthermore, when the wire support block 304 moves the wire upward, it can clamp and fix the wire through the support baffle 6 and the fixing clamp 703. Then, as the wire support block 304 continues to move upward, the support baffle 6 will push the fixing clamp 703, thereby causing the spiral spring 704 to contract. The reaction force of the spiral spring 704 will push the fixing clamp 703 to clamp and fix the wire, so that the wire can be stable during the cutting process.
