The invention discloses a bolt type safety guaranteeing structure for an elevator. The bolt type safety guaranteeing structure comprises at least two fixing mechanisms which are transversely arranged in an elevator shaft. The fixing mechanisms are connected with a power mechanism. After an elevator car reaches the floor and stops, the power mechanism drives the fixing mechanisms to transversely extend out to limit the elevator car, and the elevator car is limited from moving upwards or downwards. Fixing pins capable of performing telescopic movement are arranged, and after the elevator reaches the floor, the fixing pins extend out to limit upward or downward movement of the elevator, that the situation that after reaching the floor, the elevator suddenly falls down or rushes upwards is effectively prevented, and the safety of the elevator is greatly improved.
