Fence module

Abstract

A fence module includes fence module units each having a first pair of extensions, a second pair of extensions opposite to the first pair of extensions, and a third pair of extensions adapted to extend into a surface to stand the fence module unit upright. Each of the first pair of extensions has a through hole and each of the second pair of extensions has a cone-headed projection to correspond to one of the through holes of the first pair of extensions of an adjacent fence module unit so that connection of the cone-headed projection and the corresponding through hole is able to assemble a fence that is able to adapt to terrain.

What is claimed is:  
     
         1 . A fence module comprising: 
 fence module units each having 
 a first pair of extensions;  
 a second pair of extensions opposite to the first pair of extensions; and  
 a third pair of extensions adapted to extend into a surface to stand the fence module unit upright,  
   wherein each of the first pair of extensions has a through hole and each of the second pair of extensions has a cone-headed projection to correspond to one of the through holes of the first pair of extensions of an adjacent fence module unit so that connection of the cone-headed projection and the corresponding through hole is able to assemble a fence that is able to adapt to terrain.    
     
     
         2 . The fence module as claimed in  claim 1 , wherein the cone-headed projection has a slit defined in a center of the cone-headed projection so that two halves of the cone-headed projection are able to move toward each other by an external force when extending through the corresponding through hole.  
     
     
         3 . The fence module as claimed in  claim 2  further comprising a countersunk hole defined to correspond to the through hole of each of the first pair of extensions such that after the two halves of the cone-headed projection pass through the corresponding through hole, the two halves of the cone-headed projection spring away from each other and then abut a bottom face defining the countersunk hole after extension of the cone-headed projection into the corresponding through hole.  
     
     
         4 . The fence module as claimed in  claim 3 , wherein a holding portion is formed on top of the fence module unit and is opposite to the third pair of extensions to enable the fence module unit to be easily transported.
