Abstract:
A ratchet wrench and lighting circuit arrangement, comprising:a wrench body having first and second opposing ends; a hollow ratchet member formed of metal being mounted in said first end of said wrench body and having a pair of annular grooves formed in an axial passage thereof, said pair of annular grooves defining an upper inside annular groove and a lower inside annular groove, said hollow ratchet member including an externally threaded top neck with a circular hole formed at one end of said axial passage at a corresponding end of said hollow ratchet member, said hollow ratchet member having a polygonally shaped coupling hole at an opposing end of said axial passage, said circular hole being aligned with said coupling hole, said upper inside annular groove being disposed between said circular hole and said coupling hole, said lower inside annular groove being disposed between said upper inside annular groove and said bottom hole; a connector having an axial central through hole formed therein and upper and lower portions, said upper portion being coupled to said hollow ratchet member and having a plurality of transversely extended peripheral holes formed therein, each of said peripheral holes receiving a spring and a steel ball mounted on said spring and partially projecting therefrom, each said steel ball of said upper portion retaining said connector to said hollow ratchet member and said connector being selectively axially displaced between a first position where said steel balls are received within said upper inside annular groove and a second position where said steel balls are received in said lower inside annular groove, said lower portion having a transversely extended peripheral hole formed therein, said peripheral hole of said lower portion receiving a spring and a steel ball mounted on said spring of said lower portion and partially projecting therefrom; a cover plate having an opening formed therethrough and being coupled to said first end of said wrench body, said cover plate securing said hollow ratchet member and said connector to said wrench body; a battery holder formed of metal being threaded onto said externally threaded top neck of said hollow ratchet member, said battery holder including an electrically insulative bush and a set of batteries mounted therein, said battery set having a first terminal disposed in contact with said battery holder and a second terminal spaced from and directed toward said hollow ratchet member; and a lamp holder assembly mounted in said axial central through hole of said connector, said lamp holder assembly being axially displaceable with said connector between said first and second positions, whereby displacement said connector to said first position connects said lamp holder to said battery set and to emit light, and displacement of said connector to said second position disconnects said lamp holder assembly from said battery set and extinguishes the light.
