PURPOSE: Stationery scissors are provided to improve portability because elastic bars are inserted into or drawn out of upper and lower cases depending on the movement of upper and lower sliders. CONSTITUTION: Stationery scissors comprise upper and lower cases(200a,200b), upper and lower sliders(300a,300b), and upper and lower elastic bars(400a,400b). The upper and lower cases are fixed to the ends of upper and lower blades and comprise openings(210a,210b), rail grooves(220a,220b), and multiple locking grooves(230a,230b). The locking grooves are formed on the inner surfaces of the rail grooves at uniform intervals. The upper and lower sliders are moved along the rail grooves of the upper and lower cases. Locking protrusions(330a,330b) of the upper and lower sliders are elastically inserted into the locking grooves. One end of the upper and lower elastic bar are coupled to the upper and lower sliders, and the other ends are coupled to the ends of the upper and lower cases. The upper and lower elastic bars can be elastically deformed depending on the movement of the upper and lower sliders. |
