RETRACTABLE TYPE WRITING TOOLS FOR PREVENTING DRYNESS

摘要

The anti-drying writing instrument of the present invention has a mechanism and a spring of any one of a push type O-ring, a belt type, a wire ball type, a film type, and a fixed O-ring combined chain type inside the hollow shaft, thereby minimizing the number of assembly parts. Can provide a simplified assembly environment and improved confidentiality.;A hollow shaft 100 having a nip hole 101 of the present invention; A cartridge (110) coupled to the inside of the hollow shaft (100) so as to match the axis of the nip hole (101); A fixing plate 128 coupled to the extension shaft 112 of the cartridge 110 corresponding to one side fixing point, a fixing end 124 fixed to the hollow shaft 100 corresponding to the other fixing point, the fixing end ( A belt-shaped mechanism portion (120) having a pulley strip (121) formed between the 124 and the fixing plate (128), and a nip through hole (122) formed in the pulley strip (121); A spring (130) coupled to the extension shaft (112) located inside the belt-shaped mechanism portion (120) to couple the elastic repulsive force to the belt-shaped mechanism portion (120); And a first pushing o-ring 140 coupled to the reciprocating movement along the extension shaft 112 in a manner of operation of the pulley to move between the spring 130 and the pulley strip 121.;Belt, Writing utensils, Haunting, Dry, Pushing O-ring, Spring
