In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model relates to an earth auger which comprises an operating handle 101, a drill rod and a three-way connecting part 103, wherein the operating handle 101 is arranged on the three-way connecting part 103, the drill rod is arranged on the three-way connecting part 103, and the earth auger is simple in structure.

The drilling rod comprises a first connecting portion 102 and a drill bit portion, wherein the first connecting portion 102 and the drill bit portion are integrally formed, the strength of the drilling rod is enhanced, the drilling rod is of a hollow tubular structure, and bending is avoided during soil taking. Furthermore, the drill rod is arranged to be a carbon fiber member, and the carbon fiber member has the advantages of being high in strength, light in weight, low in cost, strong in toughness and the like. It is to be understood that the operating handle 101 may also be provided as a carbon fiber member. Further, the operating handle 101 is provided as a hollow tubular structure, avoiding bending.
