FASTENING MECHANISM IN PROPELLING PENCIL

机译:推进铅笔的融合机制

摘要

PURPOSE: To provide a clamping mechanism in a mechanical pencil to guaranteeing an effective function hardly changed even after a relatively long useful life of the pencil irrespective of an influence of a compression spring. CONSTITUTION: A split part 12 is formed with a gap 13 extending substantially in parallel. A width of a gap is specified by a diameter of a lead 8, a clamping groove 16 and depths of protrusions 22, 46. Further, guide rings 24, 43 surround split parts 12, 40 between a clamping head 14 and support flanges 18, 44. Moreover, one end of the ring is brought into contact with the flange and the other end is brought into contact with a compression spring 26.
