[Problems to be Solved by the Invention]

The conventional pushpin has the following problems. . When removing the thumbtack, usually the head A is pinched with fingers and pulled out, but it is difficult to pick with fingers because the head is flat.
If you try to force it with your finger, your nails may tear. Therefore, in some cases, the head must be pulled out by a driver or the like, and it is difficult to pull out without the driver or the like. . If the thumbtack is deeply inserted into a hard wall or pillar, if you forcibly pull it out, the head of the thumbtack will be removed and you will not be able to use it next time. In addition, the thumbtack could fly and be lost due to the force of pulling it out, or the thumbtack that fell on the floor could get stuck in the foot, which was dangerous. . Since the head of the thumbtack is small, the paper stopped by the thumbtack is easily torn and peeled off. . Because it is small, it is easy to lose unless you put it in the case,
Also, if it is lost, there is a needle and it was dangerous. In addition, it is difficult to sell unless it is put in a box or the like and it is inconvenient to store it.

An object of the present invention is to provide a thumbtack capable of securely stopping a poster, a calendar, etc., and easily removable even with a weak force, and easy to handle during sales and storage.
