The invention discloses an anti-theft lock body. The anti-theft lock body is characterized by comprising a lock body, wherein the lock body comprises a casing arranged in an open manner and a cover plate. A returning mechanism is connected between a main lock tongue and a lower cover plate and comprises a sliding plate and a regulating part for regulating the sliding plate. The sliding plate is connected with the main lock tongue. A first sliding groove, a second sliding groove and a clamping and connecting groove communicating with the second sliding groove are formed in the sliding plate. The clamping and connecting groove is perpendicular to the first sliding groove. The regulating part comprises two regulating plates. A fixing groove is formed in each corresponding regulating plate. A regulating column is connected between the two regulating plates. The regulating column penetrates through the second sliding groove and slides along the second sliding groove. A rotating hole is formed in each corresponding regulating plate. A fixing column is fixed on the lower cover plate and penetrates through the rotating holes and the second sliding groove. The regulating plates are connected with the fixing column through the rotating holes in a rotating manner. A fixing plate is also arranged on the lower cover plate. A regulating device is arranged between each regulating plate and the fixing plate. The anti-theft lock body disclosed by the invention can achieve the technical effects of being compact in structure, economical, multi-functional in use, small in center distance and small in edge distance.
