Abstract:
The aim of the present invention is to provide an improved fence jumping detection rod which can solve the problems erroneous alarms caused by unspecified external elements such as approaching animals, strong winds, or the like, and which enables the quick restoration to the original state after the detection of a fence jumping. To accomplish the aim, the fence jumping detection rod of the present invention comprises a support rod having a support portion for supporting a mesh or a line, and a shaft coupling portion extending to one side of the support portion; a shaft support coupled to the shaft coupling portion via a joint shaft to enable the support rod to swirl; an elastic ball (210) which enables the swirling of the support rod only when a torque larger than the torque set about the joint shaft acts on the shaft coupling portion; and a sensing means for sensing the swirling of the support rod. The present invention reduces erroneous alarms caused by unspecified external elements, and achieves improved fence jumping detection using the elastic ball and the elastic means.
