Description

Technical Field

[0001] The invention belongs to the field of power distribution tool equipment, and in particular relates to a portable tool for power distribution. Background Art

[0002] The most common operations in power distribution operations are cutting, connecting, and fixing various cables and other metal structures, including various transmission cables, metal wires, metal rods and other structures. These operations are usually performed using pliers such as pliers and wire cutters. Vises are suitable for iron wires or cables with small diameters and low rigidity, while wire cutters are used to cut metal cables or metal rods with high rigidity and large diameters. With the help of the principle of labor-saving levers, the intensity of manual operation can be greatly reduced, and work efficiency can be improved. They are indispensable tools in power distribution work.

[0003] However, people have also found some defects in tools such as pliers and wire cutters during use. On the one hand, due to their X-shaped lever structure, the handle part is long, and most of the cutting directions are perpendicular to the handle operation direction, which leads to the need for a large operating space for such tools, and they cannot be used in some places with narrow spaces or dense pipelines; on the other hand, since the distribution network operation often requires the operation of cables, wires, and other structures in use, these cables and wires are usually pulled at both ends and are under stress. If they are cut directly, they will fall, and the operator needs to hold the cable, which not only consumes a lot of time and energy to operate, but also cannot be directly operated in the case of long and heavy cables, and needs to be operated with the help of other fixed tensioning devices or tools such as tensioners. These tools are complicated to operate and remain unchanged when disassembled, which seriously affects the actual work efficiency. At the same time, these pliers are relatively large in size, but have relatively single functions. Summary of the invention

[0007] A portable tool of the present invention utilizes a rotating extrusion structure to achieve shearing, wherein a support seat is used to connect the overall structure, and the cable and other structures are fixed and clamped together by the through holes and clamping blocks on the support seat and the sliding seat. After being fixed, the tool will be fixed to the cable and other structures, and the cable will not separate and fall off after being cut. It can be conveniently used in a high-altitude power distribution network without worrying about the risk of cables or tools falling. The operating cylinder is pulled to the rear so that the second guide groove on the central axis coincides with the second guide block on the operating cylinder. The central axis assembly can be driven to rotate by rotating the operating cylinder. During the rotation of the central axis, it extends forward in the first threaded hole, pushing the cutting assembly forward, and then performing cutting and other operations by continuously applying pressure. After completing the cutting and other actions, the central axis assembly is rotated in the opposite direction and the cutting assembly is moved away from the cable and other structures, thereby completing the shearing and other operations. At this time, push the operating cylinder forward until the driving tooth at its front end engages with the rack on the guide bar; by rotating the operating cylinder, the two ends of the cut cable or other structure can be brought closer to each other, and the distance between the two breakpoints can be conveniently adjusted through the operating cylinder.

The limit groove can control the position of the cable, etc., to prevent the cable, etc. from rolling and deviating during cutting, resulting in cutting failure. The V-shaped cutting groove improves the cutting ability and prevents the cutter from directly colliding with the limit plate.

[0012] Further optimization of the present invention also includes that the cutter head mounting position includes a mounting arm for clamping the cutter head, and the cutter head and the mounting arm are respectively provided with threaded holes for being fixedly connected by bolts.

[0014] Further optimization of the present invention also includes that the front end of the shaft head and the contact surface are magnetized so that they can attract each other. The principle of magnetized materials attracting each other is used to facilitate the rapid disassembly and assembly of the cutting assembly.

[0015] Further optimization of the present invention also includes a stamp, a punch needle and a plurality of operating cylinders of different lengths that can be connected to the knife holder. The stamp and the punch needle are used to expand the function of the tool to achieve functions such as stamping and punching. Operating cylinders of different lengths are convenient for operating cables that are far away or close to the small space and are inconvenient to operate.
