Abstract

The present invention provides a ratchet spanner body and the manufacturing method thereof. The body comprises a handle and two heads, which is respectively penetrated with a through hole for accommodating ratchet, and has a control chamber for accommodating brake block. One groove chamber is located at one side of the control chamber and orthogonal to the axial direction of the through hole for accommodating elastic member and pushing member. The head has a first face and a second face respectively, and at least one insertion hole is provided between each face and the groove chamber. Each insertion hole is formed by pulling away the slider when drafting the casting mold. Each insertion hole penetrates from one side but does not penetrate through the other side, and each insertion hole is smaller than the elastic member and pushing member accommodated in the groove chamber. The groove chamber is constituted by summing up the occupied volume of each insertion hole extended toward the groove chamber and intersected with adjacent surfaces. Accordingly, this invention is constituted.
