The invention relates to an interchangeable pen formed by the end of the helical spring itself. He can with displaceable in a housing and around its 45, for example, with an adjacent ball scream longitudinal axis rotatably arranged ballpoint pen refill or with a suitable stop inside and a lead mine insert, the miners of which cooperate in the housing to create a dredge a screw mechanism that can be operated from the front to prevent the coil spring from increasing. Purposefully advanced can be. Sometimes the bent end of the

However, this requirement applies to a large-scale mine.
