Description

  The present invention is a nail extraction tool that easily pulls out a nail, and more specifically, has a plurality of fulcrum points at the base end of the nail extraction part at the time of nail extraction operation, and prevents slipping of this fulcrum position. The present invention relates to a nail removal tool with improved workability.

  Conventionally, there are various nail removal tools. For example, a head for forming a groove for hooking a nail head driven into a predetermined member is formed at one end of the head, and a head is formed at the other end of the head at a predetermined angle. In the nail extraction having a handle portion of a predetermined length extending in the above-mentioned manner, when the head of the nail is hooked in the groove, the head that constitutes a fulcrum at the time of nail removal by contacting the member into which the nail is driven The bottom surface of the groove is composed of a flat flat surface including the closed end from the open end of the groove, and a curved surface continuous from the flat surface and curved with a predetermined curvature around an axis parallel to the flat surface. A nail extraction bar is disclosed in which the fulcrum of the lip is started from the boundary between the flat surface and the curved surface and gradually transitions to the curved surface (see Patent Document 1).

  In addition, it is formed in a rod shape, and has a distal end portion serving as a point of action or a fulcrum, a base end portion serving as a force point, and a bent portion serving as a fulcrum or a point of action at a predetermined intermediate portion between the distal end portion and the base end portion. In addition, a bar having a non-smooth surface that stops sliding at the bent portion is disclosed (see Patent Document 2).
