The invention discloses a keyhole lock rack of an anti-theft lock and relates to the field of lockset strengthening. The problems that the anti-theft lock can be opened easily and a keyhole of the anti-theft lock is liable to be blocked are solved. According to the keyhole lock rack of the anti-theft lock, a keyhole protection bar is used for protecting the keyhole, and the keyhole protection bar is locked through a padlock, so that the keyhole protection bar can not move freely. Besides, the padlock is fixed through a hanger which is fixed to a doorknob. Meanwhile, a cover box is adopted for covering the keyhole protection bar and the padlock, and the cover box is sealed through a sliding slice. The keyhole lock rack of the anti-theft lock is simple in structure and low in cost. Two defense lines are added to an existing A type anti-theft lock, so that further strengthening of the anti-theft lock is ingeniously achieved, and the strengthening effect is very good, accordingly, people do not need to buy an expensive B type or C type lock. In addition, the A type lock is made to be firmer than the B type lock or the C type lock.
