US 2025/0375858 A1 · RATCHET WRENCH ASSEMBLY

Abstract

A ratchet wrench assembly includes a ratchet installed in a through hole of a head. The ratchet includes a through hole, an annular groove and a side opening. The through hole communicates with the annular groove via the side opening. One of two open ends of the through hole is a star-shaped opening with twelve points. Another one of the two open ends of the through hole is a hexagonal opening with six points. A C-clip is secured in the annular groove. A part of the C-clip located at the side opening is located inside the through hole. A working component has a hexagonal cross section and is inserted from the star-shaped opening end. When the working component matches with the hexagonal opening, it is movable through the through hole. When the working component is not matched with the hexagonal opening, the rod part cannot pass through the through hole.
