description The invention provides an automatic bidirectional ratchet wheel tightening mechanism. The automatic bidirectional ratchet wheel tightening mechanism comprises a head part and a driving mechanism, wherein the head part comprises a wrench head; a first extending end and a second extending end which are staggered horizontally and vertically are arranged at one end of the wrench head; a first arc-shaped groove is formed in the other end of the wrench head; an opened ratchet wheel is arranged in the first arc-shaped groove; the circular arc surface of the inner side of the opened ratchet wheel is matched with the outer contour of a bolt head to be tightened; ratchets are distributed on the circular arc surface of the outer side of the opened ratchet wheel; and two axial ends of the opened ratchet wheel are connected with the wrench head through snap rings. The automatic bidirectional ratchet wheel tightening mechanism can liberate labor force, realizes large-angle circulated quick tightening, realizes reverse tigh
