PURPOSE:To provide a component for holding a writing instrument on a position where the instrument can be gripped by the movement of a thum only (on the side of a forefinger) by bonding two cylindrical rings with adjustable diameter in a manner of varying the angle freely. CONSTITUTION:A cylindrical ring A1 (for forefinger) and another cylindrical ring B2 (for writing instrument), both of which are expandable or with adjustable diameter, are bonded together by a movable or an elastic material in the same direction or at different angles. When the bonded rings are used, the cylindrical ring A is put on the forefinger, and a writing instrument is inserted into the cylindrical ring B to fix them thereon so that the writing or other works can be performed by moving the thumb only. As a result, the necessity of changing the manner of holding the writing instrument is eliminated and also the necessity of looking for the spot where the writing is discontinued to save the working process and lessen the mental fatigue, and also the trouble of looking for a spot of placing the writing instrument and missing the same when writing is carried out at a busy site is eliminated. |
