The invention relates to a multifunctional panel anti-theft door lock which is designed for solving the technical problems that according to idle and separation and reunion structures in an existing same-class door lock, a lock cylinder assembly drives to achieve unlocking, and the lock body structure design is poor. The anti-theft door lock comprises a panel assembly and a lock body assembly, a handle of the panel assembly penetrates a panel to be connected with a square rod through a rotating assembly, and the square rod is connected with a rotating shaft in the lock body; the multifunctional panel anti-theft door lock is characterized in that the square block end of the handle penetrates the panel to be sleeved with a square hole of a first rotating block, the handle, a base and the first rotating block are connected into a whole through screws, a second rotating block and the first rotating block are buckled, and the square rod is sleeved with a rod sleeve in the center of the second rotating block; and a connecting block is formed in a block groove in the other side symmetrical to a positioning column of the first rotating block, one end of a motor above the connecting block is connected with one end of a push rod, and the other end of the push rod is connected with the connecting block. When the motor acts on the push rod to drive the connecting block so as to insert the connecting block into the block groove of the first rotating block, separation and reunion of the first rotating block and the second rotating block are achieved.
