  • Patent number: 9206830
    Abstract: A flexible positioning post includes a base, a metal post and a plurality of metal elastic pieces. The base has an upper surface. The metal post has a first end and a second end opposite to each other, and the first end is connected to the upper surface of the base. Each of the metal elastic pieces has a fixed end and a free end opposite to each other. The fixed end is securely assembled at the second end of the metal post, and the free end is adjacent to the upper surface of the base and bent toward the metal post to form a bending portion. Consequently, upon receiving a foreign force, the free end of each of the metal elastic pieces is moved toward the metal post; conversely, once the foreign force is removed, the free end of each of the metal elastic pieces is moved resiliently.
