The invention discloses a fingerprint coded lock applied to cat eye burglary prevention. The fingerprint coded lock comprises a door inside handle, a lock body, a lock cylinder arranged inside the lock body and an antitheft mechanism. An adjusting block is connected with one end of an ejector rod, and the ejector rod is sleeved with a spring. An inserting hole is formed in the door inside handle. The other end of the ejector rod is connected with a clamping head, and the clamping head penetrates through the inserting hole and the lock cylinder and then makes contact with a clamping block. A rhombus engaging head is mounted at the end of the clamping head. A transition hole is formed in the middle of the clamping block. A blind hole matched with the rhombus engaging head is formed in the bottom of the transition hole. Limiting rods matched with limiting grooves are further arranged on the outer circumferential walls of the limiting grooves. When the limiting rods make contact with the extreme positions of the limiting grooves, the rhombus engaging head aligns the blind hole, at the moment, the adjusting block is pressed downwards, the rhombus engaging head is engaged with the blind hole again, and thus it is guaranteed that the lock body can be opened normally. In this way, the time for users to adjust the position of the adjusting block continuously is shortened, and it is guaranteed that an antitheft door can be opened and closed smoothly.
