1, pinching pliers
This kind of pliers is the most common pliers, mainly used to clamp objects for drawing, bending, rotating, and: turning or assisting the processing of other tools. The heads of crucian carp are generally flat jaws (commonly known as Laisya or Sesame Laisya, which are two planes with rows of square tapered teeth like the surface of a file) and concave jaws (commonly known as walnut teeth, which means two have A curved surface with a triangular tooth pattern).
2. Pliers for cutting
This kind of pliers is mainly used to cut strips, such as gold wire, rods, nails or screws…etc. There are cutting jaws on the pliers heads, but the cutting jaws of this kind of cutting jaws are different from the cutting edges of ordinary scissors. The two blades of the scissors are interlaced, while the blades of the pliers are not interlaced with each other but only in contact with each other on the same plane, and the blades of the pliers are not only inclined on one side but double as the blades of scissors. Face tilt
Oblique, the angle of the cutting edge is also larger than that of scissors (the scissors are generally less than 30°, while the pliers are about 60°). Therefore, the cutting ability of the cutting pliers is much greater than that of scissors, and can cut hard or thick objects without chipping.
Three, composite pliers
This kind of skeletal has many uses, namely it can be pinched and cut or other uses. The shape of the pliers head is more complicated. In addition to the flat jaws and the middle jaws, it also has cutting jaws, jaws and other shapes of jaws. The function of this kind of pliers is basically the same as one of the above three functions. It is just to prevent the transmission of electricity. The handle of the pliers is covered with insulating materials, such as bakelite, rubber or other plastics, to protect the safety of users. It is a special tool for electricians.
The use of pliers is very complicated, so there are many types of samples, but the specifications are relatively simple. Generally, the straight line length from the tip of the pliers head to the tail of the pliers handle is used as the specification of the pliers. Commonly used specifications are from 100 mm M (4″) to 200 mm (8″). There are many varieties of pliers, but not all of them can be purchased from the market. Many special purpose ones are available. Special pliers need to be specially designed and manufactured according to the requirements of the messenger.
