The support insulators 22 and 24 may have a ring shape as in the present embodiment, but it is necessary to pass the end portion of the conductive wire W through the holes of the support insulators 22 and 24. Therefore, the support insulators 22 and 24 can be formed into a pigtail shape as shown in FIG. 10 (c). Then, the conductive wire W that has passed through the support insulator 22 is connected to the repeater 25 provided on the side surface of the support column 4, and is connected to the power unit that generates a high voltage pulse from the repeater 25 and supplies it to the conductive wire W. The repeater 25 may be provided with a switch that cuts off the energization of the high voltage pulse to the conductive wire W when the connecting fence 20 is opened.

When the support insulators 22 and 24 are formed into a pigtail shape, as shown in FIGS. 11 (a) to 11 (c), the conductive wire W is slid from above to below the support insulators 22 and 24 and then bent to support. The support insulators 22 and 24 can be supported by passing through the tips of the insulators 22 and 24. FIG. 11D shows a state in which the connecting fence 20 to which the casters 50 are attached is folded. As described above, since the mounting position of the caster 50 of the reference fence 10A is different from the mounting position of the caster 50 of the reference fence 10C, when the connecting fence 20 is folded, the caster 50 of the reference fence 10A and the reference fence 10C Does not interfere.

Further, when the conductive wire W is stretched between the lower frame 15 and the ground, it is necessary to stretch the conductive wire W in a pulled state. Therefore, in this embodiment, as shown in FIG. 10A, a pulley 86 is provided at the lower end of the vertical frame 14L closest to the support column 3, and the direction of the conductive wire W is changed to the direction along the vertical frame 14L. It is connected to the tension tool 80 provided on the vertical frame 14L. The tensioning tool 80 tensions the conductive wire W by pulling the conductive wire W with the force of a spring. An example of the structure for tensioning the conductive wire W will be described with reference to FIG.

FIG. 12A is a partially enlarged view of the structure of the connecting fence 20 shown in FIG. 10A that tensions the conductive wire W provided on the vertical frame 14L. A pulley 86 is provided at the lower end of the vertical frame 14L closest to the support column 3, and the direction in which the conductive wire W is stretched is changed from the horizontal direction to the direction along the vertical frame 14L. A hooking portion 85 is provided on the vertical frame 14L, and a U-shaped terminal 84 protruding from one of the tensioning tools 80 shown in FIG. 12B is hooked on the hooking portion 85. The end of the conductive wire W turned by the pulley 86 is attached to a wire attachment hook 83 protruding from the other side of the tensioner 80.

FIG. 12 (c) shows an example of the internal structure of the housing 81 of the tensioning tool 80. A compression spring 82 is housed inside the housing 81. Then, the base portion of the wire mounting hook 83 passes through the inside of the compression spring 82 and reaches the opposite side of the compression spring 82, and the end portion thereof is hooked on the end portion of the compression spring 82. Similarly, the base of the U-shaped terminal 84 passes through the inside of the compression spring 82 and reaches the opposite side of the compression spring 82, the end of which is hooked on the end of the compression spring 82. Therefore, when both the wire mounting hook 83 and the U-shaped terminal 84 are pulled out from the housing 81, they tend to return to the inside of the housing 81.

Therefore, if the tensioning tool 80 is attached to the hook portion 85, and the end of the conductive wire W is connected to the wire mounting hook 83 with the wire mounting hook 83 and the U-shaped terminal 84 pulled out from the housing 81, the conductive wire W can be formed. It is supported in a tense state between the lower frame 15 of the connecting fence 20 and the ground. In this way, the conductive wire W stretched between the lower frame 15 of the connecting fence 20 and the ground is connected to the electric fence power unit via the repeater 25 shown in FIG. 10 (a), and is raised from the power unit. By applying a voltage pulse to the conductive wire W, an electric fence can be formed on the connecting fence 20.

In addition, the size of the reference fence forming the connecting fence for livestock according to the present invention may be appropriately changed according to the type of livestock and the size of the doorway that are blocked from moving by the connecting fence. Further, the structures of the rotation holding member, the connecting member and the engaging / disengaging member are not limited to the above-described embodiment.
