Abstract

The invention relates to a ratchet wrench structure. The body of the ratchet wrench structure includes a first containing chamber, a second containing chamber, a contact edge, a click chamber, a third chamber and a fourth chamber. A ratchet is disposed in the first chamber. The ratchet includes a ratchet part, a pivot part, a contact part and a top surface. A limiting teeth set is disposed in the third chamber. The limiting teeth set includes an engaging teeth, a concave edge, a connection piece, a button and a limiting block. The limiting block is disposed at the top. The ratchet is limited by the limiting block in the first chamber. A click ring is disposed at the click chamber and in contact with the concave edge to secure the limiting teeth set in the third chamber. A top cover and an elastic element are disposed in the main body and in contact with the back of the limiting teeth set so that the limiting teeth set couples with the ratchet part. When the limiting teeth set is moved backward with button, the displacement distance is greater than the teeth distance of the limiting teeth set so that the limiting block is no longer limited at the click ring chamber and therefore the wretch can be removed.
