Abstract

The present invention relates to a grinder housing which includes a retainer capable of adjusting a height on a lower portion of a flange adjusting flatness of a ground surface, as well as including a grinding wheel to prevent a byproduct generated when a grinder grinds a processing surface from being scattered, and in which an outlet discharging a byproduct is arbitrarily adjusted in direction. The grinder comprises: a motor generating power; a grinding wheel installed on a rotational shaft of the motor and processing a processing surface; a housing covering and protecting the grinding wheel, a flange integrally formed with the housing, preventing scattering of a byproduct, and determining flatness of the processing surface, and a retainer coupled to a lower end in contact with the processing surface of the flange. When the flange integrally formed with the housing is coupled with the retainer by a fine thread bolt to turn the retainer, an amount of protrusion of the retainer is adjusted according to guide of the fine thread bolt. A plurality of position fixing recesses are formed on the outer circumferential surface of the retainer at an equal interval. A fixing pie is integrally formed with a fixing piece in which a sleeve long hole coupled by an adjustment screw and fixed to be move forwards and backwards is formed on the housing. The fixing pin is coupled to the position fixing recess formed on the outer circumference of the retainer to fix the position of the retainer whose protrusion amount has been adjusted. In coupling a byproduct discharge pipe formed on the housing to the housing, a space of coupling pieces is an equal space to form a square to facilitate change in direction to four directions. A bolt for coupling the housing to the motor is elastically supported by a spring, thereby preventing the bolt from being released even though vibration due to a grinding operation is applied to the bolt.
