Abstract
A fast self-locking mechanism is characterized by comprising a support arm, connecting elastic plates, a locking block and a rotary shaft. One end of every connecting elastic plate is in connected fit with the support arm through the rotary shaft, and the locking block is disposed at the other end of every connecting elastic plate. An operating arc surface of the locking block is concentric with an operating arc surface of the support arm. The operating arc surface of the locking block and the operating arc surface of the support arm hold an object to be held. An operating method of the fast self-locking mechanism includes: nesting the rotary shaft and the connecting elastic plates into the corresponding hole of the support arm prior to fixing, and rotating the rotary shaft and the connecting elastic plates around the axis of the rotary shaft; mounting the locking block at the other end of every connecting elastic plate, and allowing the operating arc surface of the locking block to be concentric with the operating arc surface of the support arm; placing the object to be held on the arc surface of the support arm; and rotating the connecting elastic plates to hold the object to be held. The fast self-locking mechanism has the advantages that the fast self-locking mechanism is capable of bearing high impact and never automatically opens; and the fast self-locking mechanism is simple in structure and convenient to operate.
