发明名称 Shaft section structure of scissors
摘要 Various scissor embodiments feature channel voids or passages defined within the inside surfaces of scissor blades or shaft sections. The channel voids or passages allow foreign matter to be self-expelled by the movement of the scissor blades. Disclosed blades or shafts are pivotally connected by a new connection assembly that expels foreign matter during the normal use of the scissors. Disclosed embodiments include scissors comprising: a pair of blades (1A, 1B) overlapping each other; and a shaft (3) inserted through a shaft support hole (2) in the blades (1A, 1B) and having a tip (4) that is bucked to allow the blades (1A, 1B) to pivot in an abutting state, a passage communicating with the outside to allow inflow and outflow of water, etc. is formed between abutting faces (5) of both blades (1A, 1B) and between the shaft (3) and the shaft support holes (2).

主权项 1. A pair of scissors comprising: a first blade (1A) and a second blade (1B) each having an abutting face (5) overlapping each other; a shaft (3) inserted through a shaft support hole (2) in each of the blades (1A,1B) and having a tip (4) that is bucked to allow the blades (1A,1B) to pivot in an abutting state; a recess (6) and at least one first groove (a) formed in the abutting face (5) of the first blade (1A), the recess (6) being formed around the shaft support hole (2) of the first blade (1A), and the at least one first groove (a) communicating with the recess (6) and the shaft support hole (2) of the first blade (1A); at least one second groove (b) formed in an underside of a head (7) of the shaft (3) that is inserted through the shaft support holes (2) of the blades (1A,1B), at least one receded portion (c) formed in a lateral face of the shaft (3) and extending toward the tip (4) of the shaft (3), the at least one second groove (b) extending laterally and communicating with the at least one receded portion (c); and the recess (6), the at least one first groove (a), the at least one second groove (b), and the at least one receded portion (c) forming a passage communicating with an outside of the scissors.
