Door lock prying-resistant alarm device and door lock adopting same

The utility model relates to a door lock prying-resistant alarm device which comprises an opening and closing selection module, a sensing module, an alarm module and a power supply module which are connected in series to form a trigger loop. The on-off selection module is used for controlling the on-off of the anti-prying alarm circuit; the sensing module is used for monitoring the relative distance between the door lock and the door body, and when the relative distance reaches or exceeds a critical value, the sensing module switches on the anti-prying alarm circuit; and the alarm module is used for sending out an alarm signal or an alarm sound. The induction module obtains relative distance information between the door lock and the door body, when a thief destroys the door lock and the relative distance between the door lock and the door body reaches a critical value, an internal circuit of the induction module is conducted, then the trigger loop is conducted, the alarm module is powered on to work, and the
