The present invention relates to an anti-loose socket and a pull-out locking mechanism thereof, wherein inside the anti-loose socket, there are a pull-out locking mechanism composed of a bevelled sleeve (15) and two cylinders (16) arranged in a symmetrical manner at two sides within the bevelled sleeve; an inside longitudinal section of the bevelled sleeve has a cone angle in an umbrella shape, the middle portion of the bevelled sleeve allows a plug pin (61) to pass through; the cylinder is mounted on a floating block (14) movable up and down, and can move up and down along the inside conical surface of the bevelled sleeve by the floating block. When the plug (6) is pulled out upwards, the cylingder moves upwards due to the action of a friction force and a elastic force, however due to the limiting action of the bevel surface, the cylingders stick to the two bevel surfures more and more tightly, so as to form a self-locking, such that the plug cannnot be pulled out or cannnot be easily pulled out; when the cylinders drop down, the plug can be conveniently pulled out. |
