Description

Technical Field

[0001] This utility model relates to the field of wire cutter technology, and in particular to a multi-cutting wire cutter. Background Technology

[0002] In the manufacturing process of metal products, wire cutters can cut raw steel wire into suitable lengths for making various parts. For companies that produce metal wire mesh, wire cutters are an indispensable tool. They can cut steel wire into small segments according to design requirements for weaving wire mesh of different specifications, such as sieves for screening ores, and safety nets for construction protection. In automobile manufacturing, wire cutters are used to cut steel wires used to fix parts or as internal structural reinforcements. In mechanical assembly, steel wire is frequently used for temporary fixing or auxiliary positioning. For example, in the initial assembly of large machinery, steel wire may be used to initially connect some parts to determine their relative positions; after positioning is completed, wire cutters can be used to cut these wires.

[0003] However, existing technologies, such as Chinese Publication No. CN207577312U, "A Multi-Slit Wire Cutter," disclose a multi-slit wire cutter, specifically relating to structural improvements in wire cutters. It includes a base, a fixing plate, a fixed slit, a rotating slit, and a handle. The base is fixed to a workbench with screws. The fixing plate is welded to the base and has two screw holes for fixing the slits. The fixed slit has a 160-degree arc-shaped protrusion; five slits are evenly distributed on the arc, all pointing towards the center. The fixed slit has an 8mm diameter through hole at the center of the arc. The rotating slit has a 315-degree arc-shaped protrusion with slits corresponding to the fixed slits, also pointing towards the center.

[0004] However, this device lacks a movable scissor structure to accommodate wires of different diameters by adjusting the scissor position. It cannot precisely cut the wire, and excessive force may cause wire deformation or scissor damage. It cannot be adjusted to a position that is just right for the wire thickness, and the wire is prone to slipping. The device also lacks a retractable grip structure, which cannot effectively utilize the user's strength. It cannot adapt to the hand strength and size of different users, and the grip may be too short, causing fingers to squeeze together or preventing sufficient force from being applied.

The knob 16 can drive the second threaded rod 15 to rotate inside the liner plate 14. The rotating thread will drive the internal thread. The threaded sleeve 17 is fixed to the inner surface of the pressure rod 12 by the fixing plate 18. The handle 13 can only move along the pressure rod 12 and cannot rotate. Therefore, rotating the thread will drive the handle 13 to move on the outer surface of the pressure rod 12 to adjust to the appropriate length. Place the pressure plate 1 and the device at the target position, and then place the steel wire to be cut inside the cutting groove 5. Fix the cutting blade inside the blade groove 20 of the blade housing 19, and drive the pressure rod 12 to rotate on the outer surface of the force frame 11. The pressure rod 12 will drive one end of the connecting rod 21, and the other end of the connecting rod 21 will push the blade housing 19 and the cutting blade to cut the steel wire.
