Title:
PINCHING-TYPE DRAWING PIN
Document Type and Number:
Japanese Patent JP2004058641
Kind Code:
A
Abstract:

To provide a drawing pin which, once pierced, is difficult to draw after a duration of time, is difficult to draw even if pierced into the same hole, and can be simply pierced/removed.

The drawing pin comprises two needles intersecting at a fulcrum (2) and includes a resilient plate (4) provided so that the needles (1) close by pinching a pinch part (3) and recover to the original state with the needles open if pinching fingers are released. Thus if the pinch part (3) is pinched between the fingers to close the needles (1) and the fingers are released after piercing the needles, securing force occurs as the needles (1) are to open. Therefore, once the drawing pin is pierced, it is hard to draw out even after a duration of time.
