Abstract
The invention relates to a keyhole pick-proof device of a lockset, which is divided into two parts, wherein the first part is a plane object with the size of a keyhole, the upper part, the lower part and the left part are both flat objects, the front end and the rear end are provided with the same hook columns, the second part is a key-shaped object corresponding to the keyhole, and the front end is provided with hooks, and the upper part, the lower part, the left part and the right part are both flat surfaces. The specific implementation mode is as follows: the first part is inserted into the keyhole, the key carried by the lock is pushed to the bottom, so that other people are prevented from technically picking the lock through the keyhole, when the door is opened, the second part is inserted, when the second part is pushed to the first part, the hook at the front end of the second part can hook the hook column of the first part to be connected into a whole, the first part and the second part are taken out together when the second part is pulled out, then the lock is normally unlocked by the key carried by the lock, and the fingerprint lock is very suitable for a fingerprint lock with an emergency lock.
