To materialize simultaneously a thumbtack for gypsum board having a plurality of pins with the function that pins do not come off the board once they are stuck and the function of working on it single handedly without using any tools which has a higher load resistance than an ordinary single pin thumbtack, and has a higher safety quality by integrating slanting pins onto the thumbtack body itself.
The thumbtack for gypsum board connects two plinths in movable condition; one having pins to be stuck perpendicular to the wall (perpendicular pin) and the other having pins to be stuck aslant to the wall (tilting pin). After sticking perpendicular pins of the front plinth to the wall, the tilting pins of the back plinth which penetrates the core of the front plinth are stuck to the wall, thus two kinds of different angled pins are stuck from the front plinth toward the wall.
