Abstract
A ratchet spanner comprises a body, a ratchet part, a rotating part, a brake tooth block and a push button, wherein the ratchet part and the rotating part are arranged in the body, the brake tooth block is positioned between the ratchet part and the rotating part, and the push button can be linked with the brake tooth block and accordingly can linearly slide in a reciprocating manner between a first switching position and a second switching position along the central axis parallel to the body under the action of an external force. When the push button is positioned at the first switching position, the brake tooth block is linked to contact with one side of the ratchet part, so that the ratchet part can only rotate along a direction. When the push button is positioned at the second switching position, the brake tooth block is linked to contact with the other side of the ratchet part, so that the ratchet part can only rotate along another direction. By the aid of the push button designed for axially directly pushing, better intuitive operational convenience can be provided.
