Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail puller. 2. Description of the Related Art As shown in FIG. 4, a conventional nail puller is configured such that a pinching edge 21A on both sides of a nail pulling groove 21 for holding a nail 20 has a vertical plane shape. The pinching edge 21A is formed so as to be in surface contact with the peripheral surface of the nail 20. However, in such a structure of the conventional sandwiching edge portion 21A, when the nail 20 is to be sandwiched and disposed in the nail removal groove 21 and the nail 20 is to be pulled out, the nail is not attached to the sandwiching edge portion 21A.
20 peripheral parts slip easily. For this reason, a strong force is required when pulling out the nail 20, and it is difficult to pull it out with a strong force, and it may damage the groundwork or damage the head of the nail 20. was there. SUMMARY OF THE INVENTION The present invention finds such a drawback of the conventional nail puller, and solves the drawback. The gripping edges on both sides of the nailing groove are opposed to each other. By forming it on an inclined surface that is as thin as possible and forming it into a sharp shape, the nail is hardly slipped when the sharp edge is firmly inserted into the peripheral surface of the nail and pulled out. It is intended to provide an epoch-making nail puller that can pull out the nail without removing the base and the nail without damage. The gist of the present invention will be described with reference to the accompanying drawings. In the nail puller provided with a nail pulling groove 3 at the tip of the nail puller main body 1 in which the nail 2 can be pinched, the clipping edges 3A on both opposite sides of the nail pulling groove 3 are formed in a sharp shape. In addition, each of the sandwiching edges 3A is formed into a sharpened shape by forming both of the front and back surfaces of the sandwiching edge 3A on an inclined surface that becomes thinner toward the opposing front edge side. Things. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention (how to carry out the present invention) will be briefly described with reference to the drawings, showing the operation and effects thereof. When the peripheral surface of the nail 2 to be removed is sandwiched between the opposed sandwiching edges 3A of the nail removing groove 3, each of the sandwiching edges 3A moves both the front and back surfaces of the sandwiching edge 3A toward the leading edge. Each of the sandwiching edge portions 3 is formed on a thin inclined surface to have a sharp shape.
A is firmly inserted into the peripheral surface of the nail 2 and is pinched, and the pinched nail 2 is less likely to slip with respect to the pinching edge 3A. Subsequently, the nail 2 is pulled out by operating the nail puller main body 1. At this time, as described above, the pinching edge is the nail 2
Because it is hard to slip against, it can be extracted with a light force, and it can be extracted neatly without damaging the groundwork or nails. A specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a hammer A in which a part of a handle is omitted.
This embodiment shows a case where the present invention is applied to a nail puller provided at one end of the hammer head 4 of the hammer A. More specifically, a nailing groove 3 is provided at one end of the hammer head 4 on one end side of the nailing tool body 1 so that the nail 2 can be disposed in a state of sandwiching the nail 2.
The sandwiching edges 3A on both sides facing each other are formed in a sharpened shape, and the sandwiching edges 3A are formed such that both the front and back surfaces of the sandwiching edge 3A are formed as inclined surfaces that become thinner toward the opposing front edge. It has a sharp shape. Further, the pinching edge 3A will be described in more detail. As shown in FIG.
A front side (upper side in the drawing) and back side (lower side in the drawing)
The figure shows a case where the end portion is inclined at substantially the same angle to form a sharpened shape. FIG. 3 shows another example of the sandwiching edge 3A, in which the front side of the sandwiching edge 3A is greatly inclined, and the rear side is slightly inclined to form a sharpened shape. ing. Therefore, by forming the pinching edge 3A into a sharp shape as in this embodiment or another example, the pinching edge 3A is extremely difficult to be inserted into the peripheral surface of the nail 2 and this pinching is difficult. The edge 3A firmly clamps the nail 2 to obtain an extremely excellent anti-slip effect. In this embodiment, the case where the present invention is applied to the nail puller provided on the hammer A is shown. However, the present invention can be applied to various general nail pullers as well as the present invention. Since the present invention is constructed as described above, when the peripheral surface of the nail to be removed is sandwiched between the sandwiching edges of the nail removing groove, each of the sandwiching edges becomes the same as the sandwiching edge. Because both the front and back surfaces are formed on an inclined surface that becomes thinner as the opposing front edge side, it has a sharp shape, so the gap between these sandwiched edges is firmly cut into the peripheral surface of the nail and the nail is hard to slip When the nail is pulled out by operating the nail puller body, the nail is not slippery against the pinching edge, so it can be pulled out with a light force, and the groundwork and nails may be damaged. It is an epoch-making nail removal tool with excellent practicality that can be pulled out neatly.
