Description

  The present invention relates to a plier having a tooth portion that can sandwich a split ring, a fishhook, a weight, or the like at a tip end side of a pair of crosses, and can cut a fishing line or the like.

As in the prior art document 1, a pair of long jaws are pivotally attached to each other, and a pair of jaws that taper and extend in a confronting manner on the tip side extending from the pivot center to the opposite side of the handle. A claw projecting toward the other jaw at the tip of one jaw, the length of the other jaw being longer than the length of one jaw, and between the double wound spring rings Pliers that open the doors have been proposed.
This pliers are long when carrying both the handle and chin, and the handle is long. When this handle is opened and closed, hold one handle with four fingers other than the thumb, It is easy to grip when it is necessary to place the thumb on the handle part and operate it, but it is necessary to grip it so that the operation is not cumbersome when performing a light and delicate operation.
JP-A-11-138463

  The problem to be solved is that both the handle part and the jaw part are long, so it is bulky when carrying, and the handle part is long, so when opening and closing this handle part, one handle part is used with four fingers other than the thumb. It is good when holding and holding the thumb on the other handle portion and gripping it powerfully, but there is a drawback that the operation is troublesome when performing a light and delicate operation.

  An object of the present invention is to provide a compact pliers that can be operated lightly with two fingers in view of the above drawbacks.

According to a first aspect of the present invention, there is provided a plier in which a pair of ridges are pivotally mounted so as to intersect with each other, and has a finger contact surface outside a handle portion provided on one end side of the pair of ridges. The gist of the invention is that a spring member for biasing the tip end sides of the pair of scissors to be in an open state is provided inside.
The gist of claim 2 of the present invention is that the shape of the end portion of the finger contact surface of the handle portion is a curved shape protruding in the end portion direction.
The gist of claim 3 of the present invention is that the upper surface of the finger contact surface of at least one handle portion is formed in a concave shape.

  According to the present invention, since the fingertip of two fingers can be operated so as to be pinched, it is easy to apply force even in a fine work, and it is easy to work accurately without being shaken, and a plier that is compact and easy to carry can be obtained.

A pair of rods 1 and 2 intersect, and the intersecting portions 1a and 2a are overlapped and pivotally attached to shaft screws 3 and 4 so as to be pivotable. Handle portions 5 and 6 are fixed.
Both ends of spring members 7 that open and bias the distal ends of the pair of hooks 1 and 2 are provided inside the pair of hooks 1 and 2 to which the handle portions 5 and 6 are fixed.
Finger contact surfaces 5b and 6b are formed outside the handle portions 5 and 6, and the finger contact surfaces 5b and 6b are formed in shallow recesses a and a, and in the drawing, the anti-slip protrusions 5c are formed on the finger contact surfaces 5b and 6b. A plurality of 6c are formed.
The rear end portions 5d and 6d of the handle portions 5 and 6 are formed in a curved shape protruding in the end direction.

  Hereinafter, the present invention will be described with reference to the illustrated embodiments. FIGS. 1 to 4 are the first embodiment, FIG. 1 is a side view of the pliers, FIG. 2 is a plan view of the pliers, and FIG. FIG. 4 is a side view of the pliers that pry between the double wound spring rings.

In the pliers, a pair of ridges 1 and 2 intersect at the center in the longitudinal direction, and the intersecting portions 1a and 2a are overlapped and pivotally attached by shaft screws 3 and 4, respectively.
Handle portions 5 and 6 are fixed to a pair of flanges 1 and 2 on the rear end side of the shaft screws 3 and 4 respectively.
Recesses 1b and 2b are formed inside the pair of flanges 1 and 2 to which the handle portions 5 and 6 are fixed, and the recesses 5a and 6a are also formed in the handle portions 5 and 6 at the same position. Both ends of the spring member 7 that urges the front end sides of the pair of scissors 1 and 2 to be in an open state by pressing the rear end sides of the scissors 1 and 2 are accommodated.
The rear end sides of the pair of ridges 1 and 2 protrude rearward from the handle portions 5 and 6 to become protruding portions 1c and 2c, and large and small through holes 1d and 1e are formed in the protruding portion 1c.
A hooking portion 2d is formed on the protruding portion 2c.
A locking ring 8 is attached to the small through hole 1e so that the locking ring 8 can be locked to the hooking portion 2d.
A pin 10 is fixed to the upper back surface in the cross 1a.
The intersection 2a is formed with a recess 2e that restricts the rotation range of the heel 2 with respect to the heel 1.

Finger contact surfaces 5b and 6b are formed on the outside of the handle portions 5 and 6, and the finger contact surfaces 5b and 6b are formed on the planes a and a, and in the drawing, the anti-slip protrusions 5c and 6c are formed on the finger contact surfaces 5b and 6b. Are formed.
The shape of the rear end portions 5d and 6d of the handle portions 5 and 6 on the finger contact surfaces 5b and 6b is formed in a curved shape projecting toward the end portions, and the finger pads of the fingers applied to the finger contact surfaces 5b and 6b are formed. It matches and hits.
The front sides of the crossed portions 1a and 2a of the pair of ridges 1 and 2 cross in the middle of the tip, and the tip portions 1f and 2f are overlapped on the same plane.
In the side view of FIG. 1, the front end 2 f is on the upper side and the front end 1 f is on the lower side, and the opposing surfaces of the front end 1 f and 2 f of the pair of scissors 1 and 2 hold the object. It has become.
A claw 2g and a concave portion 2h opened downward are formed on the surface of the front end portion 2f facing the front end portion 1f facing downward in the drawing.
The length of the tip portion 1f is shorter than the position of the claw 2g of the tip portion 2f.
The claw 2g, the recessed portion 2h, and the tip portion 1f constitute a function of prying open between the double wound spring rings 9.

  As shown in FIG. 4, when prying between the double-rolled spring rings 9 with a pliers, as shown in FIG. 1, the upper side is held at the tip 2f having the claw 2g and the thumb is placed on the handle 5 The locking ring 8 is removed from the hooking part 2d by pressing the index finger against the handle part 6 and the gap between the tip part 1f and the tip part 2f is opened by the urging force of the spring member 7, and the claw 2g is wound twice. By placing the handle portions 5 and 6 between the spring rings 9 and pressing the handle portions 5 and 6 to push the inner side of the double-winding spring ring 9 toward the claw 2g at the tip 1f, the double-winding spring ring 9 can be easily formed. I can break the gap.

When the pliers are configured as described above, the index finger and the thumb can be placed on the handle portions 5 and 6 to hold the pliers, and can be lightly operated with the fingertips of two fingers, so that the object is a double wound spring It is very easy to apply the tip portion 1f and the tip portion 2f to the ring 9, and it is easy to apply force, and the plier is compact and easy to carry.
At the time of operation, since the thumb is applied to the handle portion 5 so as to face the tip portion 2f side, fine work can be performed accurately.
