Wire cutter

The present invention relates to a hand tool, and more particularly to a wire cutter.

In general engineering applications, such as hydropower engineering or horticultural engineering, different working situations are often encountered and different hand tools are required to be used. Among them, the clamping and cutting of objects are relatively high frequency actions, such as gardening engineering. The common planting shape in order to shape the shape of the plant to present a special artistic conception and beauty, often uses the metal wire to wrap the stem of the plant to guide its growth direction, and the winding process will repeatedly encounter it. Clamping, shearing action. Therefore, in the course of the conventional application, the engineering staff will also prepare different hand tools accordingly.

However, using different hand tools for different jobs will face the dilemma of replacing hand tools from time to time, especially the frequent and frequent movements such as clamping and cutting, and it will waste extra time due to the replacement of hand tools. It also causes inconvenience and also affects the fluency and efficiency of the work.

Therefore, the purpose of the present invention is to provide a wire cutter that integrates the jaws and the shearing function to improve the ease of use and smoothness of the work.

Therefore, the new wire cutter pliers comprises two pliers shears and a pivot joint.

The pliers members are pivotally connected, each pliers member includes a grip end portion, a working end portion opposite the grip end portion, and a gap between the grip end portion and the working end portion The pivoting portion has a clamping section sequentially along a length direction of each of the pivoting portions, and a pair of scissors segments each having a plurality of jaws formed on the inner side thereof for clamping Each of the scissor segments has a first blade portion on the inner side for cutting, and the pliers shear members are relatively pivotable to a clamping position at which the working end portions abut each other for clamping .

The pivoting member pivotally connects the pivoting portions of the jaws.

The utility model has the advantages that the clamping operation of the clamping segments can be performed by clamping, and the first cutting edge of the scissors segments can be used for cutting work, thereby achieving integrated clamping and shearing. Cut the function in one purpose. On the other hand, especially for the treatment of wire rods (such as steel wire), the clamp segments are disposed at the front ends of the scissors segments, and can be continued as needed during clamping and cutting of the wires. The tongs clamp the ends of the wire to improve the smoothness of the work. In detail, since the wire has a certain restoring force due to its own material characteristics, after pulling it out and cutting the unnecessary part, if the end of the wire is not clamped, the remaining part is easily affected. The aforementioned restoring force is removed from the hand tool, but if the wire is to be further processed, it is necessary to take another effort to pull the pliers out again, and the new type is clamped to the scissors. At the front end of the section, the operator can bend the wire slightly to adjust the position of the wire relative to the working end before cutting the wire, so that the scissors can be cut at the scissors end when the working end is closed At the same time, the clamp segments also clamp the ends of the remaining wires, thereby improving the fluency of the work.

Referring to Figures 1 and 2, a first embodiment of the present invention relates to a second pliers shearing member 10, a pivoting member 20 for attaching the pliers members 10, and a returning resilient member 30.

The pliers members 10 are pivotally connected, and each of the pliers members 10 includes a grip end portion 1, a working end portion 2 opposite to the grip end portion 1, and a grip end portion 1 therebetween. The pivoting portion 3 between the working end portions 2 and a reset portion 4 interposed between the pivoting portion 3 and the grip end portion 1. The pliers members 10 are relatively pivotable along a pivot axis X to a pliers position and an open position. When the pliers members 10 are in the pliers position, the working end portions 2 abut each other. For clamping, when the jaws 10 are in the open position, the working ends 2 are remote from each other. The pivoting member 20 is pivotally connected to the pivoting portion 3 of the clamp members 10.

Each of the working end portions 2 has a clamping section 21, a scissor section 22, and a cutting jaw section 23 in sequence along the longitudinal direction L of each of the pivoting portions 3.

Each of the jaw segments 21 has a plurality of teeth 211 formed on the inner side thereof for clamping. When the pliers 10 are operated in the pliers position, the jaw segments 21 are engaged with each other for clamping, and collectively define a generally conical profile, and thus are suitable for insertion into a tube having a smaller inlet diameter. Or, in a more confined space, clamp the object out.

Each scissor segment 22 has a first edge portion 221 on its inner side for shearing. When the jaws 10 are operated in the jaw-cutting position, the inner edges of the first blade portions 221 overlap each other. Each of the first blade portions 221 has a flat blade surface 222 and a beveled blade surface 223 extending along the longitudinal direction L and disposed opposite to each other. Each of the inclined blade faces 223 is connected to the inner edge of each of the flat blade faces 222. Between the outer sidewalls of each of the scissor segments 22. The flat blade surface 222 of one of the first blade portions 221 faces downward, and the oblique blade surface 223 faces upward, and the flat blade surface 222 of the other of the first blade portions 221 faces upward, the inclined blade surface 223 The inner edge of the flat blade surface 222 of the first blade portion 221 is in an overcut state overlapping each other, so that the material having a relatively tough material can be more completely cut.

Each of the cutter jaws 23 has a second blade portion 231 located on its inner side for cutting. When the pliers 10 are operated in the pliers position, the second blade portions 231 of the pliers segments 23 are in close contact with each other.

It should be noted that the inner edge of each of the first blade portions 221 protrudes inwardly from the inner side surface of each of the jaw segments 21 and the inner edge of each of the second blade portions 231. Therefore, when the clamp members 10 are cut inward, When the nipper position is operative, the inner rims of the first blade portions 221 are offset from each other and overlap each other, and the inner edges of the second blade portions 231 are aligned with each other and opposite each other. Hehe.

Each of the pivoting portions 3 has a surrounding wall 31, and the surrounding wall 31 defines a shaft hole 311 through which the pivoting member 20 is disposed. The surrounding wall 31 of each pivoting portion 3 has an edge. The height at which the pivot axis X extends, and in this embodiment, the height is 5 mm. It should be noted that the height may also be other values between 4 and 7 mm.

The return elastic member 30 is disposed between the reset portions 4 and has a potential energy that pushes against the clamp members 10 opposite to the clamp position. That is, the pliers members 10 are opened toward the open position opposite to the pliers position without being subjected to external force by the user.

Referring to Figures 3 and 4, a second embodiment of the present wire cutter is substantially identical to the first embodiment, and differs from the first embodiment in that the inner side of the jaw segments 21 and thereon The formed ribs 211 have a large area to create a larger clamping area with the article and increase the force of the jaws. Further, the scissors segments 22 have a shorter length and a larger flesh thickness, thereby It can cut objects with heavy loads (such as high hardness, strong toughness, etc.).

Through the above description, the above embodiment has the following advantages, so that the purpose of the present invention can be achieved:

1. The work of clamping by the ribs 211 of the clamp segments 21, and the work of cutting by the first blade portion 221 of the scissors segments 22, can achieve the integrated clamp and shear function. In one purpose.

2. The clamping jaws 21 are disposed at the front ends of the scissors segments 22, and the ends of the wires can be continuously clamped during the clamping and cutting of the wires to improve the smoothness of the work. .

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
