Lead-replaceable writing implement with multiple lead channels

摘要

A lead-replaceable writing implement including an outer tube, an inner rod received in the outer tube and formed with multiple lead channels and a push rod, a rotary tube partially inserted into a lower end of the outer tube, and a lead holder received in the rotary tube and partially protruded beyond the lower end thereof, wherein the multiple lead channels respectively contain several series of leads of different hardness, and the rotary tube is formed with a lead stop whereby when rotating the rotary tube to locate the lead stop right above a lead channel and then push the inner rod upward, the lead stop will stop a lowest lead with desired hardness from rising and drop the stopped lead into the lead holder, and when thereafter pressing the inner rod downward, the push rod thereof will partially protrude the dropped lead beyond the lead holder for writing.
