<p>The present invention relates to a non-tool fixing device for adjusting the direction of a grinder grindstone cover, comprising a protrusion (110) protruded on one side of a grinder gear cover (100); a spring fixing groove (120) tension-formed on a circumferential face of the protrusion (110); a protrusion inserting ring (210) into which the protrusion (110) is inserted, the protrusion inserting ring being formed on a grindstone cover (200); a plurality of hanging holes (220) formed to keep regular spaces along a circumferential direction of the protrusion inserting ring (210); and a fixed spring inserted and fixed into the spring fixing groove (120), and having a hanging unit (320) of which a partial length is elastically hung in the hanging hole (220). In accordance with the present invention, the direction of the grindstone cover can be controlled without using a separate tool, and, accordingly, while working at various angles, the direction cover can be controlled rapidly and conveniently.</p> |
