[Technical field to which the invention belongs]

 The present invention relates to a plier, and more particularly to a plier suitable for clamping and processing a wire rod or the like.

[0002]

[Problems to be solved by the device]

 Conventionally, as this type of pliers, a pair of handle bodies having a holding portion having a holding surface having a plurality of fine linear irregularities formed laterally on the tip side and a handle on the base end side are provided as the holding portion. It has been used that is rotatably pivoted by a joint mechanism on the base end side of. And, it was used for processing such as bending by sandwiching a wire material between the sandwiching surfaces having a plurality of irregularities.

By the way, applications of such pliers include, for example, production and repair of cages for shellfish such as pearl oysters and scallops. As shown in FIG. 8, the cage for pearl shells and scallops has a frame 13 made by bending a covered wire 12 installed on a bag 11 made of synthetic resin and placed inside the net 11. The pearl shells are put in and the net 11 is hung on a raft provided in a farm, and after 1 to 3 years of aquaculture, it is fried at the beach for aquaculture. The frame 13 used for such a cage for pearl shells and scallop shells is manufactured by the farmer himself by bending the coated wire rod 12 with pliers according to the size of the net 11 used. Further, when the sea becomes rough, the frame 13 is deformed or damaged, but even in such a case, the covered wire 12 was bent and extended by pliers for repair.

However, in the frame body 13 that constitutes the aquaculture basket, there is a portion 13A where the coated wire rod 12 is bent at about 90 degrees, and a portion 13B where the coated wire rod 12 is bent so as to be folded back. Moreover, in the case of repair, the intricately curved covered wire 12 may be once straightened and then bent again into a predetermined shape. Further, the coated wire rod 12 may be curved at an intermediate portion or may be bent at an end portion thereof, and thus the coated wire rod 12 may be curved in various ways. Nevertheless, in the conventional pliers, linear concavities and convexities are formed on the clamping surface in the lateral direction, and the covered wire 12 is clamped along the linear concavities and convexities. The problem is that it is not suitable for greatly bending the wire rod 12, for straightly extending the covered wire rod 12 that is complicatedly curved, and then bending it again into a predetermined shape, or for bending only the tip of the covered wire rod 12. was there. In addition, since the linear irregularities on the pinching surface of the pliers are formed finely, the covered wire rod 12 is thicker, so it is difficult to hold it firmly, and if a large force is applied, the covered wire rod 12 will come off and workability will increase. Was not good enough.

Further, not only in the shellfish cage as described above, but also in pliers for gardening and work, when a wire such as a wire is bent into a desired shape and used, the same problem occurs. is there.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a plier suitable for clamping and processing a wire rod or the like.

[0007]

[Means for Solving the Problems]

 The pliers according to claim 1 of the present invention include a pair of handle bodies each having a curved gripping portion having a gripping surface abutting each other at a tip end thereof and a handle on a proximal end side thereof, and between the gripping portion and the handle. The pliers are rotatably and pivotally attached to a support shaft portion formed in the above, and lateral and vertical groove portions are formed on at least one holding surface of the pair of handle bodies. By adopting such a configuration, when the handle is grasped, the holding surface comes into contact with the wire rod and the wire rod is firmly held by holding the wire rod in one of the lateral and vertical grooves formed in the holding surface. can do. In addition, since the groove portion that holds the wire rod can be selected in the horizontal direction or the vertical direction depending on the position, degree or direction of bending the wire rod, it is suitable for bending the wire rod into various shapes.

Further, in the pliers of claim 2, the lateral and vertical groove portions are formed on both of the sandwiching surfaces of the pair of handle bodies, and the groove portions have a semicircular shape, and the sandwiching surfaces are mutually connected. When abutting, the groove portions of the pair of handle bodies are aligned with each other to form a circular through hole. By adopting such a configuration, the wire rod is sandwiched by the circular holes formed by the groove portions in the horizontal direction and the vertical direction, so that the stability when sandwiching the wire rod is improved and the work efficiency is improved. be able to.

According to a third aspect of the pliers, at least one of the handles of the pair of handle bodies has a base end portion which is sharp and flat. By adopting such a configuration, when the tip of the wire is in close contact with another member, the tip of the wire is formed by penetrating the base end of the sharp and flat handle as a wedge. By lifting the wire, the tip of the wire can be held by the holding surface.

The pliers according to claim 4 are made of stainless steel. Therefore, it is unlikely to rust and is particularly suitable for applications where it is exposed to water, salt, and the like.

Further, in the pliers according to the fifth aspect, the groove portions in the horizontal direction and the groove portions in the vertical direction have substantially the same width and are orthogonal to each other. Therefore, when the wire rod is sandwiched by the circular holes, it can be similarly stably clamped regardless of whether it is sandwiched by the groove portions in the horizontal direction or the vertical direction. Further, since the groove portions in the horizontal direction and the groove portions in the vertical direction are orthogonal to each other, workability in bending the wire rod into various shapes is further improved.

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4, reference numeral 1 denotes a plier, and the plier 1 is composed of a pair of stainless steel handle bodies 2 and 2A pivotally mounted on a support shaft portion 3 by a pivot member 4. The pedestals 2 and 2A include a holding portion 5 formed in a curved shape from the distal end side, a flat plate-shaped supporting shaft portion 3 having a continuous pivot hole 3A narrowing from the holding portion 5, and the support. It comprises a rod-shaped handle 6 on the base end side of the shaft 3. The tip of the sandwiching portion 5 is a sandwiching surface 7, and a semicircular first groove portion 8 is sandwiched in the sandwiching surface 7 in the lateral direction with respect to the axis S direction of the handle bodies 2 and 2A. A second groove portion 9 which is formed across the surface 7 and is orthogonal to the first groove portion 8 and has substantially the same width as the first groove portion 8 is formed in the vertical direction, that is, the axis of the handle body 2 or 2A. It is formed by vertically cutting the holding surface 7 in the S direction. The base end of the handle 6 of one of the handle bodies 2 is sharp and flat to form a wedge-shaped portion 6A. Then, the pair of handle bodies 2 and 2A are superposed on the support shaft portion 3 so that the holding surfaces 7 face each other, and the positions of the pivot holes 3A are aligned and fixed by the pivot member 4. When assembled and brought into contact with the sandwiching surfaces 7 of the pair of handle bodies 2 and 2A, a circular hole 8A is formed which is aligned with the first groove portion 8 and penetrates in the lateral direction, and the second groove portion 9 is formed. Are formed so that a circular hole 9A penetrating in the vertical direction is formed.

The operation of the above configuration will be described. For example, when bending the middle portion of the covered wire rod 12 of the covered wire rod 12, as shown in FIG. 5, the middle portion of the covered wire rod 12 is sandwiched between the first groove portions 8 of the holding surfaces 7 of the pair of handle bodies 2 and 2A. It suffices to clamp and to apply a force so as to bend with the lateral ends of the clamping surfaces 7, 7 as fulcrums. At this time, since the first groove portions 8 and 8 are semicircular and the holding surfaces 7 and 7 are brought into contact with each other, the first groove portions 8 and 8 are aligned with each other to form a circular hole 8A in the lateral direction. Since the covered wire rod 12 is sandwiched between the holes 8A, the covered wire rod 12 can be stably and firmly held without derailment, and the workability is good.

When the tip of the covered wire 12 is folded back, as shown in FIG. 6, the end of the covered wire 12 is held between the second groove portions 9 of the holding surfaces 7 of the pair of handle bodies 2 and 2A. It suffices to clamp and to apply a force so as to bend with the tips of the clamping surfaces 7, 7 as fulcrums. At this time, the second groove portions 9 and 9 have a semicircular shape, and when the holding surfaces 7 and 7 are brought into contact with each other, the second groove portions 9 are aligned with each other to form a circular hole 9A in the vertical direction. Since the coated wire rod 12 is sandwiched between 9A, the coated wire rod 12 can be stably and firmly held without derailment, and the workability is good.

Further, as shown in FIG. 7 (a), when the end of the covered wire 12 is in close contact with another portion of the covered wire 12, it is difficult to hold the tip as it is. As shown in Fig. 7 (b), after inserting the wedge-shaped portion 6A to lift the end portion with the handle 6 as a fulcrum, the pair of handle bodies 2 and 2A of the clamping surfaces 7 and 7 It suffices to hold the end portion of the covered wire 12 between the groove portions 9 and 9 and apply a force so as to bend the tip end portion of the holding surface 7 or 7 as a fulcrum.

As described in detail above, the pliers 1 of the present embodiment have the curved holding portion 5 having the holding surfaces 7, 7 that abut each other on the tip side and the handle 6 on the base end side. A pair of handle bodies 2 and 2A are rotatably pivotally attached by a support shaft portion 3 formed between the holding portion 5 and the handle 6, and a holding surface 7 of the pair of handle bodies 2 and 2A. , 7 has a first groove portion 8 formed in the horizontal direction and a second groove portion 9 formed in the vertical direction. Therefore, when the handle 6 is grasped, the holding surfaces 7, 7 come into contact with each other, By sandwiching the covered wire rod 12 in either the first groove portion 8 or the second groove portion 9 formed in 7, 7, it can be firmly held. Further, the groove portion that holds the covered wire rod 12 can be selected by the first groove portion 8 or the second groove portion depending on the position, degree, direction, etc. of bending the covered wire rod 12, so that the covered wire rod 12 can be variously used. It is suitable for bending into a shape.

Further, the first groove portion 8 and the second groove portion 9 are formed on both of the sandwiching surfaces 7, 7 of the pair of handles 2, 2A, and the first groove portion 8 and the second groove portion 9 are formed. 9 is a semi-circular shape, and when the holding surfaces 7 and 7 are brought into contact with each other, the respective groove portions are matched with each other to form circular holes 8A and 9A, so that the holes 8A and 9A are covered with these holes. By sandwiching the wire rod 12, the stability when the wire rod 12 is sandwiched is improved, and the work efficiency can be improved.

Further, since the wedge-shaped portions 6A are formed at the base ends of the handles 6 of the pair of handle bodies 2, when the tip of the covered wire rod 12 is in close contact with another portion of the covered wire rod 12, By inserting the wedge-shaped portion 6A and lifting the tip of the covered wire rod 12, the tip of the covered wire rod 12 can be held by the holding surface.

Moreover, since the horizontal and vertical grooves 8 and 9 have substantially the same width and are orthogonal to each other, when the covered wire 12 is sandwiched by the circular holes 8A and 9A, Even if it is sandwiched between the groove portions 8 and 9 in both the vertical and vertical directions, the covered wire rod 12 can be stably sandwiched similarly. Further, since the horizontal and vertical grooves 8 and 9 are orthogonal to each other, workability in bending the covered wire rod 12 into various shapes is further improved.

Since the pliers 1 are made of stainless steel, they are unlikely to rust and are suitable for applications that are exposed to water, salt and the like.

The present invention has been described above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the curved holding portions 5 and 5 have blade portions. May be provided, and a function of cutting the covered wire rod 12 and the like with this blade portion may be added. Furthermore, although the first groove portion 8 and the second groove portion 9 are formed on both the sandwiching surfaces 7, 7 of the pair of handle bodies 2 and 2A in the present embodiment, either one may be formed depending on the case. The shape, size, etc. can be appropriately changed according to the shape and size of the covered wire 12. Further, in the above-mentioned embodiment, the case where the coated wire rod 12 is curved has been described, but the present invention is not limited to this, and it can be suitably used for ordinary wire rods, thin rods and the like.

The pliers of the present invention as described above are suitable not only for processing the wire rod in manufacturing and repairing the frame 13 of the aquaculture basket, but also for gardening and work. Needless to say, it can be used not only for processing wire rods, but also for pulling out nails and bending plate materials as with ordinary pliers.

The handle is rotatably and pivotally attached by a support shaft portion formed on the above-mentioned handle, and at least one sandwiching surface of the pair of handle bodies has a groove portion formed in the horizontal direction and the vertical direction. When the wire is grasped, the holding surface comes into contact with the wire, and the wire can be held tightly by holding the wire rod in one of the groove portions formed in the holding surface in the horizontal direction and the vertical direction. In addition, the groove for holding the wire rod can be selected in the horizontal direction or the vertical direction according to the position, degree or direction of bending the wire rod, which is suitable for bending the wire rod into various shapes.

Further, in the pliers according to claim 2, the lateral and vertical groove portions are formed on both of the sandwiching surfaces of the pair of handle bodies, and the groove portions are semicircular, and the sandwiching surface is formed. When abutting against each other, the groove portions of the pair of handle bodies are matched with each other to form a circular hole. Therefore, sandwich the wire between the circular holes formed by the horizontal and vertical groove portions. As a result, the stability when the wire rod is clamped is improved, and the work efficiency can be improved.

In the pliers according to claim 3, since at least one of the handles of the pair of handle bodies has a base end portion formed into a flat shape with a sharp tip, the tip of the wire rod is closely adhered to another member. In this case, the distal end of the wire can be clamped by the clamping surface by penetrating the base end of the sharp and flat handle as a wedge and lifting the tip of the wire.

Since the pliers of claim 4 are made of stainless steel, they are rust-resistant and are particularly suitable for applications where they are exposed to moisture, salt and the like.

Further, in the pliers according to claim 5, since the groove portions in the horizontal direction and the groove portion in the vertical direction have substantially the same width and are orthogonal to each other, when the wire rod is sandwiched by circular holes, the horizontal direction is set. Even if it is sandwiched by either the vertical groove portion or the vertical groove portion, the wire rod can be stably sandwiched similarly. Moreover, since the groove portions in the horizontal direction and the groove portions in the vertical direction are orthogonal to each other, workability in bending the wire into various shapes is further improved.
