摘要： Disclosed is a safety knock-type writing utensil capable of maintaining an outer shell (1) in a relatively thin thickness and making a length of a writing lead (2) substantially long by the change of the locking position, thereby allowing a large amount of ink to be stored therein. The safety knock-type writing utensil includes: an outer; a clip (5) assembled on the end portion of the outer; a writing lead (2) inserted into the interior of the outer shell (1) and having ink stored in the interior thereof and a tip on the end of the one side thereof; an elastic member installed in the interior of the outer shell, for applying a force in an opposite direction of the tip (21) against the writing lead; a moving member (6) movably inserted in the top portion of the outer shell and having a predetermined length of safety protrusion inserted into the interior of the moving groove in a length direction thereof, the safety protrusion having a fixed projection extruding outwardly to be locked on the locking projection of the clip; a pressing member having a pressing protrusion inserted movably into the interior of the moving member at the part of the lower portion thereof and being contacted with the upper surface of the moving member at the outer peripheral surface of the center portion thereof; and a knock member (8) inserted movably into the moving member, for maintaining the advanced state of the writing lead if the pressing member is pressed once in the state where the fixed projection of the moving member is locked into the locking projection of the clip, and for operating the writing lead in a backward direction by the elastic force of the elastic member if the pressing member is repressed.
