The invention discloses a bolt anti-theft lock. The bolt anti-theft lock comprises a lock shell, a lock cover, a lock body panel, a main bracket, an upper fluted disc, a lower fluted disc, a cross latch, a transmission mechanism, a lock cylinder and a key, and is further provided with at least one button bolt and an expansion bolt which are both fixed on the main bracket; a latch bucking hole is formed in the button bolt; an ejector pin liner is mounted in the expansion bolt; an ejector pin set is arranged in the expansion bolt; by turning the key, the transmission mechanism drives the main bracket to enable the button bolt and the expansion bolt to extend out, meanwhile enable the transmission mechanism to insert the cross latch on a doorframe side into the latch bucking hole. The bolt anti-theft lock has the effect of prying resistance. The transmission mechanism can not only drive a bolt to extend, but also drive a cross latch mechanism in a doorframe through an internal ejector pin, so as to ensure that the cross latch is inserted into the latch bucking hole in the button bolt, so that the possibility that a door is pried is eradicated.
