The present invention relates to a hanging device for a working rod of a grass cutter. A grass cutter (10) comprises: a body (11) including an engine; a working rod (13) with a grip (12); a rotating blade (14) installed at a tip of the rod (13) to rotate; and a protecting cover (15) surrounding upper and rear side surfaces of the rotating blade (14). The present invention comprises: a rotation support rod (20) installed in a cylindrical groove (22), formed on an upper installation bar (21) of the upper portion of the body (11), to be rotated by a disc bracket (23); a coupling (30); a first vertical rod (40) screwed with the top of the coupling (30); a length control unit (50) combined with the top of the first vertical rod (40); a second vertical rod (60) combined with the upper part of the length control unit (50); an L-shaped coupling (70) combined with the top of the second vertical rod (60); a horizontal rod (80) including a ring (80a) formed in an end part, and a screw thread formed in the other end part, to be horizontally screwed with the L-shaped coupling (70); and an elastic wire (90) connected between the ring (13a) of the working rod (13) and the ring (80a) of the horizontal rod (80). Therefore, the present invention is capable of making grass cutting work safe, convenient, and efficient by equally distributing the weight of the working rod over the human body and making the height of the rotating blade equal, reducing costs for manufacturing by using a convenient and simple structure, and having a good economic feasibility by enabling long use without malfunction. |
