  Hereinafter, embodiments of the present application will be described in detail based on specific examples with reference to the accompanying drawings.

  Fig.1 (a) shows the state between the forests where the conductive wire 5 was stretched using the wire support for electric fences of this invention. The conductive wire 5 can be easily passed between trees by being held by the electric fence wire support 4 of the present invention attached to the nail member 3 driven into the trunk 2 of the tree 1. A region surrounded by (hereinafter simply referred to as wire 5) can be formed. Embodiments of the wire support 4 for an electric fence of the present invention attached to the nail member 3 will be described below based on some examples.

  FIG. 1B shows an operation of attaching the first embodiment of the wire support 4 for an electric fence of the present invention to the trunk 2 of the tree using a nail member 3 made of hard synthetic resin. It is assumed that a wire 5 is preliminarily wound around the trunk 2 of the tree with a predetermined tension. In this state, the nail member 3 is driven in the vicinity of the trunk 2 where the wire 5 is locked. Since the nail member 3 is long, the nail member 3 may be inserted into the electric fence wire support 4 as shown in the drawing.

  FIG. 1B shows an electric fence wire support 4 according to the first embodiment of the present invention, which includes a cylindrical main body 10. The main body 10 is shown in detail in FIG. 2A as a single body, but is a cylindrical body having a predetermined thickness and includes an insertion hole 14 for inserting the nail member 3. The main body 10 is attached to the nail member 3 and has two wire holes 11 for penetrating the wire 5 in the vicinity of the end portion 15 far from the trunk portion 2 and the end portion 15 of the wire 5. A groove 12 leading from the side to the wire hole 11) is provided. In the first embodiment, the diameter of the wire hole 11 is equal to the width of the groove 12, and the groove 12 is smoothly connected to the wire hole 11 in the longitudinal direction of the main body 10. Usually, the nail member 3 is first driven and fixed to the trunk 2 of the tree, and the insertion hole 14 of the main body 10 is inserted into the nail member 3.

  When the nail member 3 is driven and fixed to the trunk portion 2 of the tree and the electric fence wire support 4 is attached to the nail member 3, the wire 5 stretched over the trunk portion 2 shown in FIG. Then, it is pulled up from the trunk 2 and inserted into the groove 12 of the wire support 4 for electric fence attached to the nail member 3. This state is shown in FIG. Here, FIG. 2 shows the inner diameter of the insertion hole 14 with respect to the diameter of the nail member 3, the positions of the wire holes 11 and the grooves 12, and the state of the wire 5 held by the main body 10 in the first embodiment of the present invention.
