Pliers can be divided into: clamp twist type according to performance; Shear type; Clamp torsional shear type. It can be divided into: hydraulic tongs; Crimping pliers; Hydraulic conductor pliers; Wire stripper; Rechargeable hydraulic cable clamp. According to the shape, it can be divided into: sharp nozzle; Flat mouth; Round mouth; Curved mouth; Inclined nozzle; Needle mouth; Top cut; Wire pliers; Flower gill forceps, etc. It can be divided into DIY, industrial pliers, special pliers, etc. According to the structure, it can be divided into two types: penetrating gill and overlapping gill. The general specifications are: 4.5 "(mini pliers), 5", 6 ", 7", 8 ", 9.5", etc.
The main categories are as follows:
Wire pliers
The steel wire clamp is a kind of clamp and cutting tool, and its shape is shown in Figure 1 on the right.
The steel wire pliers are composed of a tong head and a tong handle, and the tong head includes a tong mouth, a tooth mouth, a knife edge, and a cutting mouth. The functions of each part of the pliers are: ① The tooth mouth can be used to fasten or loosen the nut; ② The knife edge can be used to cut the rubber or plastic insulation layer of the flexible wire, and can also be used to cut the wire and iron wire; ③ The cutting mouth can be used to cut hard metal wires such as wires and steel wires; ④ The insulated plastic pipe of the pliers can withstand voltage of more than 500V, with which the electric wire can be cut. In use, do not litter. To avoid damaging the insulated plastic pipe. The wire cutters commonly used by electricians include 150mm, 175mm, 200mm and 250mm.
Needle nose pliers
Sharp nose pliers, also called mouth repair pliers, are mainly used to cut single strand and multi strand wires with thin wire diameter, bend single strand conductor joints, strip plastic insulation layer, etc. It is also one of the tools commonly used by electricians (especially interior line electricians). The utility model is composed of a sharp head, a knife edge and a clamp handle. The handle of needle nose pliers for electricians is sheathed with insulating sleeve with rated voltage of 500V. Due to the sharp head of the needle nose pliers, the use of the needle nose pliers is related to the operation in a narrow space. The operation method of bending the wire connector with the needle nose pliers is: first turn the wire head to the left, and then turn it to the right in a clockwise direction close to the screw.
Wire stripper
Wire stripper is one of the tools commonly used by internal electricians, motor repair and instrument electricians. Its appearance is shown in Figure 2. The utility model is composed of a knife edge, a crimping mouth and a clamp handle. The handle of wire stripper is sheathed with insulating sleeve with rated working voltage of 500V.
Wire stripper is suitable for peeling plastic and rubber insulated wires and cable cores.
