Pencil with writing-core feeding mechanism and continuous use

The utility model relates to a continuous application pencil that can be filled refills repeatedly, belonging to the pencil producing field. The technical problem solved is that: the refills in the pencil can be rotated and shifted by a spire device, pushed forward linearly and used in writing. The utility model is characterized in that the refill 3 is lifted and stabilized in a rotary drum 5 by an elastic module 2 combined with a pen mouth 1 and an outer sleeve 4. When a stem 8 is rotated, a shifting top 6 in the rotary drum 5 does spiral motion along a spiral orbit 7 and shifts down along a rotary drum pipeline 9, and the refill 3 is pushed forward. The utility model has the advantages of different specifications and being used in writing, painting, drawing and other ways according to a plurality of needs.
