Ice auger

Abstract

An ice auger includes a drive member, an upright bar, and a saw barrel. The drive member is coupled with a top end of the bar, and a bottom of the bar is coupled with a top center of the saw barrel, which is circular mug-shaped with a downward opening. The saw barrel has pores at its top side, saw blades on its bottom fringe, and a chipping-ejecting blade upward spirally extended from an outer sharp edge of each said saw blade along its outer periphery. Whereby, the ice auger of a preferably simplified structure is provided.

What is claimed is:  
     
         1 . An ice auger comprising: 
 a bar;    a drive member coupled with a top end of said bar; and    a boring member, which is circular mug-shaped with a downward opening, having a top side coupled with a bottom of said bar, pores positioned at the top side thereof, saw blades disposed around a bottom periphery thereof, and a chipping-ejecting blade upward spirally extended from an outer sharp edge of each said saw blade along the outer periphery of said boring member.    
     
     
         2 . The ice auger as defined in  claim 1 , wherein said bar is rail-shaped and formed a T-shape with said bar.  
     
     
         3 . The ice auger as defined in  claim 1 , wherein said drive member is steering-wheel-shaped.  
     
     
         4 . The ice auger as defined in  claim 1 , wherein said drive member is arched and has an end coupled with the top end of said bar, the other end provided with guide pad, and a middle section provided with a rotatable handle.  
     
     
         5 . The ice auger as defined in  claim 1 , wherein said bar is detachably coupled with said drive member.  
     
     
         6 . The ice auger as defined in  claim 5 , wherein said bar has a polyangular connecting post, and said drive member is substantially rail-shaped and has a cylindrical coupler at the center thereof, said coupler having an axial polyangular hole for said connecting post to be inserted in.  
     
     
         7 . The ice auger as defined in  claim 6 , wherein said connecting post of said bar horizontally has a through hole, and said coupler of said drive member has two radial opposite vents for corresponding to and communicating with said through hole of said connecting post, said two vents and said through hole being inserted through by a pin.  
     
     
         8 . The ice auger as defined in  claim 1 , wherein said bar is fixedly fastened with said drive member.  
     
     
         9 . The ice auger as defined in  claim 1 , wherein said bar is detachably coupled with said boring member.  
     
     
         10 . The ice auger as defined in  claim 9 , wherein said bar has a threaded post at its bottom and said boring member has a connecting tube with an inner thread at its top center for coupling said threaded post of said bar.  
     
     
         11 . The ice auger as defined in  claim 1 , wherein said bar is fixedly fastened with said boring member.
