Description

Composite pliers

Technical Field

The application relates to the technical field of shearing tools, in particular to a pair of composite pliers.

Background

Pliers are hand tools for gripping, twisting, or shearing workpieces. The pliers are generally V-shaped and generally comprise a handle, a pin shaft and a pliers head. The tong head is provided with two vertical side surfaces, an inner cutting edge is arranged on one vertical side surface, and an outer cutting edge is arranged on the other vertical side surface, so that a shearing opening is formed for shearing an object.

At present, water pliers and inclined pliers are commonly used in the market, wherein the water pliers are mainly used for shearing soft objects such as plastic products, so that the pliers heads of the water pliers are basically in a single-cutting-edge structure, namely, the inner cutting edge has a certain angle, and the outer cutting edge is flat so as to shear a smooth shearing surface; the diagonal pliers are generally designed to be double-cutting edges, namely the inner cutting edges have a certain angle, the outer cutting edges also have a certain angle, and the double-cutting edges enable the strength of the cutting edges to be higher, so that the diagonal pliers are mainly used for shearing objects which are long and thin and have relatively high hardness, such as steel wires and iron wires.

But in the in-service use process, it is very arduous to discover that diagonal pliers and water-jet pliers are all when shearing some thicker article to in some complicated operating mode use occasions, operating personnel need frequent change two kinds of pliers at least to adapt to the article shearing work of different materials, further caused the use inconvenience.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

a pair of composite pliers comprises a pair of pliers bodies, wherein each pliers body comprises a pliers handle and a pliers head arranged at one end of the pliers handle in the length direction, one ends of the two pliers handles, which are close to the pliers heads, are hinged, inner inclined surfaces which are matched with each other are arranged on the side faces of the two pliers heads, which are positioned on the same side, one sides of the inner inclined surfaces, which are close to each other, are gradually inclined towards the insides of the pliers heads, an inner cutting edge is formed between the two inner inclined surfaces, the angle of the inner cutting edge is 140 degrees, outer inclined surfaces are arranged on the side faces, which are opposite to the inner cutting edge, of the two pliers heads, one sides of the outer inclined surfaces, which are close to each other, are gradually inclined towards the insides of the pliers heads, an outer cutting edge is formed between the two outer inclined surfaces, and the angle of the outer cutting edge is 130 degrees.

By adopting the technical scheme, compared with the diagonal pliers, the angle of the inner cutting edge of the composite pliers is larger than 90-110 degrees of the diagonal pliers and the water-jet pliers, so that the opening and closing space between the two inner inclined planes is larger, when some thicker objects exceeding more than 6mm are sheared, the two inner inclined planes do not generate conflict on the surfaces of the objects when the objects are sheared to a certain depth, the shearing process can be smoothly carried out, the use is more labor-saving, and the applicability is improved; compared with a water gap clamp, the other vertical side face of the composite clamp is provided with the outer cutting edge, and the existence of the outer cutting edge enables the section of a shearing part formed by the edge of the inner inclined plane and the edge of the outer inclined plane and in contact with an object to be an acute triangle, so that the shearing strength is improved. To sum up, this compound pincers can cut thicker article to this compound pincers have succeeded the advantage of diagonal pliers and water-jet pliers rationally, can also can cut stereoplasm articles such as steel wire simultaneously to cut soft articles such as working of plastics, and the function is comparatively suitable for, and it is more convenient to use.

In a preferred embodiment of the present invention, the side of the binding clip facing away from the inner cutting edge is an inclined surface, and the inclined surface is gradually inclined toward the inside of the binding clip when being away from the handle.

By adopting the technical scheme, the compound pliers can be used for tilting the bound objects such as nails and the like during use, so that the functions of the compound pliers are further increased, and the compound pliers are more convenient to use.

In a preferred embodiment of the present invention, the width of the outer slope is equal to or less than 1/10 of the maximum width of the slope.

Through adopting above-mentioned technical scheme, the area on outer inclined plane sets up less to reduced the area of outer blade, still can keep comparatively level and smooth shear plane when cuting plastic products, thereby suitable advantage between having combined diagonal pliers and the water jet pliers improves convenient to use nature.

As a preferred aspect of the present application, the angle between the inclined surface and the inner inclined surface is 15 to 20 degrees.

As a preferred scheme of this application, two the side that pincers handle is close to mutually has all seted up places the hole, two place and be equipped with the spring between the hole, spring length direction's both ends fixed connection respectively places downtheholely.

Through adopting above-mentioned technical scheme, the spring is used for strutting between two handles, struts the incision relatively easily, and is more laborsaving in the use.

As a preferable scheme of the application, the side surface of the two adjacent clamp handles is also provided with sawteeth for stripping the thread skin.

Through adopting above-mentioned technical scheme, in the wiring work progress, can utilize the sawtooth to peel off the line skin for this combination pliers's function is abundanter, improves convenient to use nature.

As a preferred scheme of the application, the side surface of one of the forceps handles is provided with a pressing line protrusion, and the side surface of the other forceps handle is provided with a pressing line groove used for matching and pressing the protrusion.

Through adopting above-mentioned technical scheme, the protruding cooperation wire pressing groove of line ball can be with end of a thread crimping in binding post, has further richened the function of this compound pincers, has improved the convenience of using.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the inner cutting edge angle of the composite pliers is set to be 130 degrees and 140 degrees, so that the composite pliers can be well adapted when a thicker object is sheared, and the outer cutting edge is arranged on the pliers head of the composite pliers, so that the strength of a shearing opening is improved, a harder object can be sheared, the advantages of the inclined-mouth pliers and the water-jet pliers are integrated, and the composite pliers are convenient to use;

2. the width of the outer cutting edge is smaller than 1/10 of the width of the inclined surface, so that when a plastic product is sheared, the shearing surface can still keep a smooth state, and the using effect is good;

3. through setting up the protruding and wire pressing groove of line ball, sawtooth and inclined plane for this compound pincers can carry out the function of line ball, wire stripping and nail nipping respectively, have further richened the function of this compound pincers, have improved the convenience of using.
