We usually come across some situations including that we are easily injured by the pushpin which is bare outside and it’s hard to pull out when the pushpin is knocked in. Aiming at these two problems, we have designed this type of pushpin. This pushpin has a layer of soft materials named silica gel used as a protective jacket avoiding the bare pushpin; The bottom becomes warped outward slightly, only in this way can make us find its edges easily then pull out the pushpin. Meanwhile,for the being of this structure, we also could use this pushpin to hang some things.
