ABSTRACT:
A bi-directional ratchet spanner with a ratchet control structure includes a first receiving portion for receiving a ratchet; a second receiving portion for receiving a braking block; and a third receiving portion for receiving a switch unit. The wall of the third receiving portion has a first trench and a second trench. One end of the switch unit in the third receiving portion is formed with a concave portion and a through hole. The concave portion receives one end of a positioning rod. Another end of the positioning rod is received in a sliding trench of the braking block; and a control element is received in the through hole. By moving the switch unit, the positioning rod and control element will control the rotation direction of the ratchet. The conductive wire includes a steel ball, a spring and a top rod.
