Abstract
A ratchet wrench structure includes a first body, a ratchet wheel, a second body, a control rod, and a magnetically attractive block. The first body has a first receiving recess. The ratchet wheel is pivotally mounted in the first receiving recess and has a mounting portion, a second receiving recess, and a first abutting edge. The second body is mounted in the second receiving recess and has a third receiving recess, a fourth receiving recess, and a second abutting edge. The control rod is mounted in the second body and has a third abutting edge, a press portion, a shank, and a push face. The magnetically attractive block is received in the second receiving recess and located between the second body and the first abutting edge.
