ABSTRACT:
The base seat of a dual-directional ratchet wrench has a protective rim enclosing the perimeter of the sandwich parts. The rectangular windows are arranged on the protective rim at the positions corresponding to those of two lugs of the set regulator so as to ensure that the sandwich parts are embraced completely after the disposition of the set regulator in the base seat. The inner side of the protective rim is a smooth surface devoid of the flange so that modifications of molding apparatus for manufacture of sandwich parts, set regulators, etc. are not required.
