Abstract
A fastening mechanism which is easy to handle and operate. The fastening mechanism includes a bolster, a bolt, at least two elbows, and a support bracket. The bolster is provided with several retainer walls externally disposed, one side thereof being formed into an opening and the inside thereof being formed into a hollow space with a passage through which the bolt can pass. At least two elbows extend from the bottom end of the retainer walls. When the bolt mates with the inner thread formed in the retainer wall, a friction plate formed with the support bracket lodges into a tapered slot between two retainer walls so that the support bracket cannot move against the retainer walls. The at least two elbows angle outwards to retain the support bracket when the bolt is traveling along the inner thread.
