A normal anti-theft lock is divided into three main parts, namely the panel handle (door handle), the lock cylinder, and the lock body. Generally, they are purchased separately when they are purchased. The three parts are related, but not all belong to each other.
The mechanical structure of the lock body tube is opened and closed, the lock core tube is for safety protection, and the main panel of the panel is manually opened and closed. Therefore, when buying anti-theft door locks, they are usually purchased separately. The indoor door locks generally do not take the initiative to indicate that they are purchased as a set.
