The lock fastener is provided with a movable hole for the fastener head to pass through, and a limiting hole communicated with the movable hole is arranged on the side. The fastener head and the lock fastener are respectively rotatably assembled on the first pull head and the second pull head. When the fastener head passes through the movable hole and relatively moves with the lock fastener to be embedded in the limiting hole, mutual locking can be achieved. However, the above existing double-button anti-theft pull head is relatively inconvenient to operate and has poor mechanism stability when in use. In view of the above problems, the inventor of this case conducted in-depth research on this problem, and thus this case was born.
