Abstract:
The present invention relates to a hand grinder coupler structure that can more simply and quickly attach/detach a machining disk coupled to a rotary shaft of a grinder main body so as to be used for polishing the surface of an object to be machined, trimming, cutting or the like. The present invention simplifies a linking component of a coupler mounted on the rotary shaft of the grinder main body, so that manufacturing costs can be greatly reduced, and enables the consumable disk to be easily attached to or detached from the coupler with one touch so that a replacement operation is quickly performed during machining, and thus efficiency can be greatly improved.
