The invention discloses a single-cylinder double-safety lock. The single-cylinder double-safety lock comprises a lock body, a main lock holding ring and a secondary lock holding ring, wherein the main lock holding ring comprises a main movable connection end; the main movable connection end is movably connected with the lock body; a first limit part is arranged at the main movable connection end; the secondary lock holding ring comprises at least one secondary movable connection end; the secondary movable connection end is movably connected to the lock body; a second limit part is arranged at the secondary movable connection end; a lock cylinder and a lock catch unit are arranged on the lock body; a clamping part matched with the first limit part and the second limit part is arranged on the lock catch unit; when the lock is locked, the clamping part of the lock catch is matched with the first limit part and is used for limiting the main lock holding ring to not to be opened; the clamping part is matched with the second limit part and is used for limiting the secondary lock holding ring to not to be opened. According to the single-cylinder double-safety lock, the main lock holding ring and the secondary lock holding ring share the same lock cylinder, so that the lock is capable of locking vehicle, locking the fixed objects except the vehicles, preventing the thieves from carrying the vehicles away and improving the anti-theft effect.
