Quadrangular ice

According to the technical scheme, the quadrangular ice comprises an ice body and a rod body, ice teeth are arranged on the upper portion of the ice body, connecting trousers are arranged on the lower portion of the ice body, and the connecting trousers are connected with the rod body; each ice tooth comprises two triangular tooth plates, and the two tooth plates are fixedly installed on the top of the ice body in a crossed mode. The quadrangular ice is simple in structure, high in strength, obvious in drilling and ice crushing effects on an ice layer, and time-saving and labor-saving. 本实用新型采用的技术方案是：一种四棱冰镩，包括冰镩本体和杆体，冰镩本体的上部为冰镩齿，下部为连接裤，连接裤与杆体连接；所述冰镩齿包括两块三角形齿板，两齿板呈十字交叉形式固定安装在冰镩本体的顶部。这种四棱冰镩结构简单，强度大，在冰层上的钻孔、碎冰效果明显，省时省力。
