Claims

[Scope of utility model registration request]

In the mechanism for inserting and removing the tip of a ballpoint pen, the pen shaft of the ballpoint pen is made of three types of e.g. metal pipes, large, medium and small, with different diameters, and fitted together to form a three-stage shaft of an elastic pipe, and a base pipe, an intermediate pipe, and a tip. As a pipe, connect the threaded part of the tip pipe to the sliding pipe and screw it into the fixed hollow threaded metal fitting.Insert a mekugi between the sliding parts of the sliding part of the sliding pipe, and attach the core holder to the outside of the intermediate pipe. Insert it inside, connect and fix it to the shaft of the mekugi, and assemble it, insert it into the base pipe 5, and insert it into the base pipe 5 so that the ratuparo part of the sliding pipe and the sushi-shaped part of the convex part of the intermediate pipe are on the inner surface of the base pipe. A retractable re-centering ballpoint pen characterized in that it is assembled so that it can slide in sliding contact and that a base fitting is inserted and fixed to the inner end of the base pipe.
